• "Error in the Site Data Web Service." when performing crawl

  - by Janis Veinbergs

  Installed SharePoint Services v3 (SP2, october 2009 cumulative updates, Language Pack), attached to a content database I had previously (all works). Installed Search server 2008 Express (with language pack) on top of WSS and crawl does not work. However it works for newly created web application + database. Was playing around with accounts, permissions to try get it working. Currently I have WSS_Crawler account with such permissions: Office Search Server runs with WSS_Crawler account Config database has read permissions for WSS_Crawler Content database has read permissions for WSS_Crawler WSS_Crawler is owner of search database. Added WSS_Crawler to SQL server browser user group and administrator Yes, i'v given more permissions than needed, but it doesn't even work with that and i don't know if its permission problem or what. Crawl log says there is Error in the Site Data Web Service., nothing more. There were known issues with a similar error: Error in the Site Data Web Service. (Value does not fall within the expected range.), but this is not the case as thats an old issue and i hope it has been included in SP2... Logs are from olders to newest (descending order). They don't appear to be very helpful.

• nagios NRPE: Unable to read output

  - by user555854

  I currently set up a script to restart my http servers + php5 fpm but can't get it to work. I have googled and have found that mostly permissions are the problems of my error but can't figure it out. I start my script using /usr/lib/nagios/plugins/check_nrpe -H bart -c restart_http This is the output in my syslog on the node I want to restart Jun 27 06:29:35 bart nrpe[8926]: Connection from 192.168.133.17 port 25028 Jun 27 06:29:35 bart nrpe[8926]: Host address is in allowed_hosts Jun 27 06:29:35 bart nrpe[8926]: Handling the connection...

• SSL / HTTP / No Response to Curl

  - by Alex McHale

  I am trying to send commands to a SOAP service, and getting nothing in reply. The SOAP service is at a completely separate site from either server I am testing with. I have written a dummy script with the SOAP XML embedded. When I run it at my local site, on any of three machines -- OSX, Ubuntu, or CentOS 5.3 -- it completes successfully with a good response. I then sent the script to our public host at Slicehost, where I fail to get the response back from the SOAP service. It accepts the TCP socket and proceeds with the SSL handshake. I do not however receive any valid HTTP response. This is the case whether I use my script or curl on the command line. I have rewritten the script using SOAP4R, Net::HTTP and Curb. All of which work at my local site, none of which work at the Slicehost site. I have tried to assemble the CentOS box as closely to match my Slicehost server as possible. I rebuilt the Slice to be a stock CentOS 5.3 and stock CentOS 5.4 with the same results. When I look at a tcpdump of the bad sessions on Slicehost, I see my script or curl send the XML to the remote server, and nothing comes back. When I look at the tcpdump at my local site, I see the response just fine. I have entirely disabled iptables on the Slice. Does anyone have any ideas what could be causing these results? Please let me know what additional information I can furnish. Thank you! Below is a wire trace of a sample session. The IP that starts with 173 is my server while the IP that starts with 12 is the SOAP server's.

• Why does DEP kill IE when accessing Microsoft FTP?

  - by Sammy

  I start up IE (9.0.8112.16421) with about:blank and I go to ftp://ftp.microsoft.com/ I press Alt, click View and then Open FTP Site in Windows Explorer. At this point IE stops responding and eventually crashes (though the window is still active, sometimes) and I get the usual Windows dialog box saying that the program has stopped working. From this dialog box I click on the option to try to find solutions to the problem and the progress bar just keeps scrolling without giving me any result page whatsoever, so I have to abort by clicking Cancel. Then I get the bubble type of pop-up message from the system tray saying that DEP has stopped the program from executing. What gives? Why would DEP (part of Microsoft Windows) be preventing IE (a Microsoft product) from performing a perfectly legitimate action from Microsoft's own FTP site? The OS is Windows Vista HP SP2, Swedish locale. Screenshots as follows... Update: I normally have UAC disabled, but I have discovered that enabling it has an effect on IE when I click the FTP option from the View menu, just as I suspected. I basically tried starting IE in its 32-bit and 64-bit version, with and without add-ons, and switching UAC on and off, and then trying to go to View and the FTP option (as shown above). Here are the results. With UAC off and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: information & warning message This is the information and warning message I get if I use IE 64-bit: The first message is an FTP proxy warning. It says that the folder ftp://ftp.microsoft.com/ will be write-protected because proxy server is not configured to allow full access. It goes on to say that if I want to move, paste, change name or delete files I must use another type of proxy, and that I should contact the system admin for more information (the usual recommendation when they have no clue of what's going on). What the heck is all this about? I don't even use a proxy server, as you can see from the next screenshot (Internet Options, Connections, LAN settings dialog). That second message only states that the FTP site cannot be viewed in (Windows) Explorer. With UAC off, I always get these two messages when running the 64-bit version of IE. With UAC on and DEP on Action: IE 32-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: crash Action: IE 32-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, normal start, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action Action: IE 64-bit, extoff, go to ftp://ftp.microsoft.com/, view menu, FTP option. Result: security warning message, prompts to allow action As you can see from this list, if I have UAC enabled I actually get rid of these messages and opening the FTP site in Windows Explorer (from IE) actually works (except for 32-bit version which still crashes). Here is the security warning message: The fact that the 32-bit IE still crashes could be an indicator that this has something to do with one or several add-ons in that bit-version of IE. The 32-bit IE doesn't crash if it's started with the extoff flag. If this is affecting only the 32-bit IE then it's only normal that the 64-bit IE doesn't have this problem because it would not be using any of the add-ons used by the 32-bit version, they are not compatible with 64-bit (although some add-ons work both with 32-bit and 64-bit IE). Figuring out which add-on (if any) is causing this problem is a whole new question... but I seem to be closer to an answer now, and a possible solution. I could of course just add IE (32-bit) in the exclusion list of DEP. In fact, I have already tested this and it causes IE to perform this task without hiccups. But I don't really want to disable DEP, or force it on all Windows programs and services (except the ones I strictly specify in the exception list). (In other words DEP can't really be completely disabled, you can only switch between two modes of operation.) Update 2: This is interesting... I start 32-bit IE, go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. The result is a crash!! Then I start 32-bit IE with extoff flag to disable add-ons, I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. I get the security warning, as expected with UAC enabled, and it opens up in Windows Explorer. Now... I close Windows Explorer, and I close IE. I then start 32-bit IE (normal start, with add-ons), I go to ftp://ftp.microsoft.com/ and click on View, and Open FTP Site in Windows Explorer. Now this time it doesn't crash! Instead, I get the screenshot number 5 as seen above. This is the FTP proxy warning message. Now get this... if I click the close button to get rid of this message, what happens is that Firefox starts up, and it goes to ftp://ftp.microsoft.com/ The fact that this works with 32-bit IE (with add-ons) the second time around, is because I am still logged in as anonymous to the FTP server. The log-in has not timed out yet. Standard log-in timeout for FTP servers is usually 60 to 120 seconds. I got logged in to it the first time I ran 32-bit IE with the extoff flag (no add-ons) which actually works and connects using Windows Explorer. Update 3: The connection to the FTP server has timed out by now. So now if I run 32-bit IE (with add-ons) and repeat the steps as before it crashes, just as expected... In conclusion: If I have already been connected to the FTP server via Windows Explorer, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu to open it in Windows Explorer, it gives me a FTP proxy server warning and then opens the address in default web browser (Firefox in my case). If I have not been connected to the FTP server via Windows Explorer previously, and I go to this FTP address in 32-bit IE and I pick the FTP option from the view menu top open it in Windows Explorer, then it crashes IE! This is just great... It's not that I care much for using Internet Explorer or the Windows Explorer to log in to FTP servers. This just shows why IE is not the best browser choice. This reminds me of the time when Microsoft was enforcing the use of Internet Explorer as default browser for opening web links and other web resources, despite the fact that the user had installed an alternative browser on the system. Even if the user explicitly set the default browser to be something else and not Internet Explorer in the Windows options, IE would still pop up sometimes, depending on what web resources the user was trying to access. Setting default browser had no effect. It was hard-coded that IE is the browser of choice, especially when accessing Microsoft product or help pages. The web page would actually say that you are not using IE, and that you must open it in IE to view it. Unfortunately you would not be able to open it manually in a different browser by simply copying and pasting the URL from the address bar, because it would show a different URL, and the original URL would re-direct to the "you are using the wrong browser" page so you would not have the time to cut it to clipboard. Thankfully those days are over. Now-days Microsoft is forced to distribute IE and WMP free versions of Windows for the EU market. The way it should be! These programs have to be optional, not mandatory.

• saslauthd + PostFix producing password verification and authentication errors

  - by Aram Papazian

  So I'm trying to setup PostFix while using SASL (Cyrus variety preferred, I was using dovecot earlier but I'm switching from dovecot to courier so I want to use cyrus instead of dovecot) but I seem to be having issues. Here are the errors I'm receiving: ==> mail.log <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.info <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.warn <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure I tried $testsaslauthd -u xxxx -p xxxx 0: OK "Success." So I know that the password/user I'm using is correct. I'm thinking that most likely I have a setting wrong somewhere, but can't seem to find where. Here is my files.

So, I'm now at a loss... I have no idea where to go from here or what steps I need to do to get this working =/ Anyone have any ideas? EDIT: Here is the error that is coming from auth.log ... I don't know if this will help at all, but here you go: Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql auxprop plugin using mysql engine Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: begin transaction Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin create statement from userPassword user xxxxxx.com Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin doing query select crypt from users where id = '[email protected]'; Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin create statement from cmusaslsecretPLAIN user xxxxxx.com Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin doing query select crypt from users where id = '[email protected]'; Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: commit transaction Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1' Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: begin transaction Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin create statement from userPassword user xxxxxx.com Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin doing query select crypt from users where id = '[email protected]'; Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin create statement from cmusaslsecretPLAIN user xxxxxx.com Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin doing query select crypt from users where id = '[email protected]'; Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: commit transaction Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin Parse the username [email protected] Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin try and connect to a host Aug 11 17:19:56 crazyinsanoman postfix/smtpd[9503]: sql plugin trying to open db 'maildb' on host '127.0.0.1'

• JSF Portlets in Liferay on JBoss

  - by JBirch

  I'm currently looking at working with and deploying JSF portlets into Liferay 6.0.5, sitting on JBoss 5.1.0. I ran into a lot of trouble trying to port some JSF-y/Seam-y/EJB-y stuff I had lying around, so I thought I'd start simple and work my way up. I could generate generic portlets using the NetBeans Maven archetype for Liferay portlets absolutely fine, but it's rather irrelevant because I wanted JSF portlets I took an example JSF portlet from http://www.liferay.com/downloads/liferay-portal/community-plugins/-/software_catalog/products/5546866 and attempted to deploy into a clean, vanilla installation of Liferay 6.0.5/JBoss 5.1.0 to no avail. The log messages are reproduced at the end of this. This particular example was actually tested for GlassFish and Tomcat, so it's not particularly helpful considering I'm deplying into JBoss. I tried ripping it apart and removing the jsf implementation contained within as there is a jsf implementation shipped with JBoss (Mojarra 1.2_12, in this case). 03:16:17,173 INFO [PortletAutoDeployListener] Copying portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war Expanding: /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war into /tmp/20110201031617188 Copying 1 file to /tmp/20110201031617188/WEB-INF Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 1 file to /tmp/20110201031617188/WEB-INF/classes Copying 47 files to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Copying 1 file to /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/jboss-5.1.0/server/default/deploy/richfaces-sun-jsf1.2-facelets-portlet.war Deleting directory /tmp/20110201031617188 03:16:20,075 INFO [PortletAutoDeployListener] Portlets for /usr/local/[REDACTED]/liferay/liferay-portal-6.0.5/deploy/richfaces-sun-jsf1.2-facelets-portlet-1.2.war copied successfully.

• --log-slave-updates is OFF but some updates are still logged to the slave binary log?

  - by quanta

  MySQL version 5.5.14 According to the document, by the default, slave does not log to its binary log any updates that are received from a master server. Here are my config. on the slave: # egrep 'bin|slave' /etc/my.cnf relay-log=mysqld-relay-bin log-bin = /var/log/mysql/mysql-bin binlog-format=MIXED sync_binlog = 1 log-bin-trust-function-creators = 1 mysql> show global variables like 'log_slave%'; +-------------------+-------+ | Variable_name | Value | +-------------------+-------+ | log_slave_updates | OFF | +-------------------+-------+ 1 row in set (0.01 sec) mysql> select @@log_slave_updates; +---------------------+ | @@log_slave_updates | +---------------------+ | 0 | +---------------------+ 1 row in set (0.00 sec) but slave still logs the some changes to its binary logs, let's see the file size: -rw-rw---- 1 mysql mysql 37M Apr 1 01:00 /var/log/mysql/mysql-bin.001256 -rw-rw---- 1 mysql mysql 25M Apr 2 01:00 /var/log/mysql/mysql-bin.001257 -rw-rw---- 1 mysql mysql 46M Apr 3 01:00 /var/log/mysql/mysql-bin.001258 -rw-rw---- 1 mysql mysql 115M Apr 4 01:00 /var/log/mysql/mysql-bin.001259 -rw-rw---- 1 mysql mysql 105M Apr 4 18:54 /var/log/mysql/mysql-bin.001260 and the sample query when reading these binary files with mysqlbinlog utility: #120404 19:08:57 server id 3 end_log_pos 110324763 Query thread_id=382435 exec_time=0 error_code=0 SET TIMESTAMP=1333541337/*!*/; INSERT INTO norep_SplitValues VALUES ( NAME_CONST('cur_string',_utf8'118212' COLLATE 'utf8_general_ci')) /*!*/; # at 110324763 Did I miss something? Reply to @RolandoMySQLDBA: If replication brought this over, then the same query has to be in the relay logs. Please go find the relay log that has the INSERT query with the same TIMESTAMP (1333541337). There is no such query with the same TIMESTAMP in the relay logs. If you cannot find it in the relay logs, then look and see if Infobright is posting the INSERT query. In that instance, the INSERT should be recorded in the binary logs of the Slave. Looking more deeply into the binary logs, I see that almost of the queries are CREATE/INSERT/UPDATE/DROP "temporary" tables, something like this: # at 123873315 #120405 0:42:04 server id 3 end_log_pos 123873618 Query thread_id=395373 exec_time=0 error_code=0 SET TIMESTAMP=1333561324/*!*/; SET @@session.pseudo_thread_id=395373/*!*/; CREATE TEMPORARY TABLE `norep_tmpcampaign` ( `campaignid` INTEGER(11) NOT NULL DEFAULT '0' , `status` INTEGER(11) NOT NULL DEFAULT '0' , `updated` DATETIME, KEY `campaignid` (`campaignid`) )ENGINE=MEMORY /*!*/; # at 123873618 #120405 0:42:04 server id 3 end_log_pos 123873755 Query thread_id=395373 exec_time=0 error_code=0 SET TIMESTAMP=1333561324/*!*/; DROP TABLE IF EXISTS `norep_tmpcampaign1` /* generated by server */ "temporary" here means that they are dropped after calculation is done. I also tells the slave not to replicate any statement matches the norep_ wildcard pattern: replicate-wild-ignore-table=%.norep_% But there is an exception table in the binary logs: # at 123828094 #120405 0:37:21 server id 3 end_log_pos 123828495 Query thread_id=395209 exec_time=0 error_code=0 SET TIMESTAMP=1333561041/*!*/; INSERT INTO sessions (SessionId, ApplicationName, Created, Expires, LockDate, LockId, Timeout, Locked, SessionItems, Fla gs) Values('pgv2exo4y4vo4ccz44vwznu0', '/', '2012-04-05 00:37:21', '2012-04-05 00:57:21', '2012-04-05 00:37:21', 0, 20, 0, 'AwAAAP////8IdXNlcm5hbWUGdXNlcmlkCHBlcm1pdGlkAgAAAAQAAAAGAAAAAQABAAEA', 0) /*!*/; Description: mysql> desc reportingdb.sessions; +-----------------+------------------+------+-----+---------------------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------------+------------------+------+-----+---------------------+-------+ | SessionId | varchar(64) | NO | PRI | | | | ApplicationName | varchar(255) | NO | | | | | Created | timestamp | NO | | 0000-00-00 00:00:00 | | | Expires | timestamp | NO | | 0000-00-00 00:00:00 | | | LockDate | timestamp | NO | | 0000-00-00 00:00:00 | | | LockId | int(11) unsigned | NO | | NULL | | | Timeout | int(11) unsigned | NO | | NULL | | | Locked | bit(1) | NO | | NULL | | | SessionItems | varchar(255) | YES | | NULL | | | Flags | int(11) | NO | | NULL | | +-----------------+------------------+------+-----+---------------------+-------+ I'm sure all these queries are posting by MySQL, not Infobright: $ mysql-ib -u root -p Enter password: Welcome to the MySQL monitor.

• BSOD Before Windows Will Loads - Graphics Related

  - by Brian

  Alright deep breath here: (Windows 7 Home Premium 64 bit btw) Today I installed Star Craft 2 Beta. After trying to log in, it had some issues where it said my device stopped working (referring to my video device I have to imagine). After I force quit the game there were some random "hot" (various colors if i remember correctly) pixels on the screen. I decided to reboot and try again with similar results. I figured that maybe my display drivers could stand to be updated (I don't frequently update them as I don't often run into problems). I went out to nVidia's website and grabbed the latest drivers for Windows 7 64 bit GeForce 9 series. (I have SLi-ed 9800 GTs). Everything seemed to install fine and I performed the restart. This is when things went from bad (can't play SC2 beta ;) ) to worse (can't boot into windows!). Initially the very first splash screen - I think it's the bios splash screen - had lines of colored pixels covering it. It then displayed a screen that had lots of "(" on it. After that it showed the normal windows 7 splash screen as if it were going to load into Windows. Before getting much further, it BSODed on me. It was a 0x0000003B stop error. At nvlddmkm.sys. A little digging let verified that this was a problem with an nVidia graphics device, not a real shocker. Windows decided it would try to help me diagnose the problem, which it's only answer to was a System Restore, which did nothing to alleviate the problem. I was able to boot up fine in safe mode and was not able to roll back the driver, however I did uninstall the driver and reboot. I still had the graphical anomalies during the first two screens (same colored "."'s and weird "("'s), but there was NOT a stop error. Windows loaded up, found a default driver for the device and installed it and I restarted to let it load - and had yet another BSOD Stop error. Repeat driver uninstall, this time I reloaded the same version (I think it's possible that I was running a 32 bit version or a vista versus windows 7 version, but I don't have that information handy) of the nVidia driver from their website. Restart, same anomalies, same Stop Error. I am at a loss - At this point all I can think is that the firmware for the Video cards got fried or there's actual damage to the cards which I sincerely hope is not the case but the sooner I know the better. Any insight into what I might be able to do to troubleshoot/fix this problem would be most helpful. Attached below is a dump from DxDiag.

• SQL Server 08 Express error when connecting to localhost - "Timeout expired". Works with ::1 or 127

  - by Adam A

  EDIT New info: Navigating to localhost:1434 in Chrome gives me an "ERR_EMPTY_RESPONSE", while other ports give me an "Oops! This link appears to be broken". So it seems to binding ok there? So here's my setup so far: I've configured Windows Firewall to allow TCP on 1433 and UDP on 1434. I've set up SQL Server to use any IP on Port 1433 (using the SQL Server Configuration Manager). My hosts file contains the default entries ("127.0.0.1 localhost" and "::1 localhost"). I sometimes have a debug session of Visual Web Developer running a webserver, but it's on a specific port (localhost:5XXXX). What I've tried: I CAN ping localhost in a cmd prompt. I CAN connect to the database through SSMS if I specify 127.0.0.1 or ::1 as the server name. I CAN'T connect to the database through SSMS (or ADO.NET) if I specify localhost as the server name. I've tried both Windows and SQL Authentication The error I get is the standard Can't connect to localhost. Additional Information -- Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft Sql Server) Other considerations: Stopping the Visual Web Developer web server from the taskbar doesn't affect the sql problem. The SQL error log says that it's listening on some piped name url at start up (I don't see how this would affect localhost but not 127.0.0.1 though). I could probably just use 127.0.0.1 everywhere, but it scares me that localhost isn't working and I'd like to figure out why. I'm not much of a networking or sql server guy so I'm stuck. If you want me to try anything to help diagnose just put it in a comment and I'll give it a go.

• webserver horrible slow, sometimes incredible fast

  - by dhanke

  i am running a small community ( 6000+ Members ) on a non-virtual 64-bit ubuntu 11.04 system. I am not a Linux-pro, not even advanced, i just tried to setup a webserver, which does nothing special actually. Delivering some dynamic PHP and RoR websites is its task. So it might be that my configuration files do look horrible bad. Also, i might use the wrong vocabulary, so in doubt, please ask. Having a current all-time record of 520 registered users (board-accounts, no system-users) online at same time, average server-load is about 2.0 - 5.0. Meantime (~250 users) average server load value is at about 0.4 - 0.8, sometimes, on some expensive searches a bit higher. everything fine. From time to time however, the load increases up to 120 (120.0, not 12.0 ;) ). In this time, its hard to even connect via SSH, but when i reach the server, and use top/htop/iotop to see whats happening, i cannot identify any process causing high CPU load. iotop tells me about a current reading/writing speed of about approx. 70kb/s, which is quite equal to power-off i think. Memory-Usage is max. at ~ 12GB of 16GB, so swap remains empty. now the odd (at least for me:) waiting some minutes ( since i always get a bit into a panic when this happens, it feels like 5 minutes, but i suppose its more like 20-30 minutes) and the server is back to normal. everything continues as normal. another odd fact: when i run hdparm -tT /dev/sda, i get answer like: /dev/sda: Timing cached reads: 7180 MB in 2.00 seconds = 3591.13 MB/sec Timing buffered disk reads: 348 MB in 3.02 seconds = 115.41 MB/sec when i run the same command while the server is "frozen", the answer is like /dev/sda: <- takes about 5 minutes until this line appears Timing cached reads: 7180 MB in 2.00 seconds = 3591.13 MB/sec <- 5 more minutes Timing buffered disk reads: 348 MB in 3.02 seconds = 115.41 MB/sec <- another 5 minutes so the values are the same, but the quoted time is completely wrong. using time command as prefix also tells me that ~ 15 minutes were used. I searched in dmesg, /var/log/[messages|syslog] - nothing found. /var/log/errors however tells me that: Jul 4 20:28:30 localhost kernel: [19080.671415] INFO: task php5-fpm:27728 blocked for more than 120 seconds. Jul 4 20:28:30 localhost kernel: [19080.671419] "echo 0 /proc/sys/kernel/hung_task_timeout_secs" disables this message. multiple times. now that message does tell me that php5-fpm task was blocked or did block ? - but not if that is the cause or just one of the results of that "freeze". Anyone? to cut the long story short, i dont know where even to start analyzing. So if you can give me any advice by looking at following specs and configs, or ask me to provide more information, i`d be glad. Specs: 6 Core AMD Phenom(tm) II X6 1055T Processor * 16 Gigabyte Ram 2x 1.5 TB Seagate ST1500DL003-9VT16L via SATA 3 via SoftwareRaid (i suppose) Services: (due to service --status-all, those with [ + ]) nginx Webserver 1.0.14 mySQL 5.1.63 Server Ruby on Rails 2.3.11 ( passenger-nginx-module ) php5-fpm 5.3.6-13ubuntu3.7 SSH ido2db Further services: default crontab + nightly backup. syslog-ng Website consists of 2 subdomains, forum. and www. where forum is a phpBB3.x PHP-Board, and www a Ruby on Rails 2.3.11 application (portal). Mini-Note: sometimes i notice that the forum is pretty slow, in contrast to the always-fast (except for this "freeze") portal. Both share the same Database, but the portal is using it read-only. The Webserver is nginx, using phusion passenger module to communicate with the ruby-application. Also, for the forum it communicates with php5-fpm via socket: relevant nginx configuration parts ( with comments/questions starting by ; ) ; in case of freeze due to too high Filesystem activity, maybe adding a limit? #worker_rlimit_nofile 50000; user www-data; ; 6 cores, so i read 6 fits. maybe already wrong? worker_processes 6; pid /var/run/nginx.pid; events { worker_connections 1024; } http { passenger_root /var/lib/gems/1.8/gems/passenger-3.0.11; passenger_ruby /usr/bin/ruby1.8; ; the forum once featured a chat, which was working w/o websockets. ; so it was a hell of pull requests (deactivated now, freeze still happening) keepalive_timeout 65; keepalive_requests 50; gzip on; server { listen 80; server_name www.domain.tld; root /var/www/domain/rails/public; passenger_enabled on; } server { listen 80; server_name forum.domain.tld; location / { root /var/www/domain/forum; index index.php; } ; satic stuff to be handled by nginx location ~* ^/style/.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ { access_log off; expires 30d; root /var/www/domain/forum/; } ; now the php magic, note the "backend"-fcgi_pass location ~ .php$ { fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_pass backend; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/domain/forum$fastcgi_script_name; include fastcgi_params; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_intercept_errors on; fastcgi_ignore_client_abort off; fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 256 16k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_max_temp_file_size 0; } location ~ /\.ht { deny all; } } ;the php5-fpm socket. i read that /dev/shm/ whould be the fastes place for this. bad idea in general? upstream backend { server unix:/dev/shm/phpfpm; } ... } php5-fpm settings (i changed this values due to php5-fpm error log messages higher and higher..

One additional Fact: my MYSQL-database is at 12GB size. i dont know if that does matter, but mytop sometimes shows me 4-5 seconds long insert queries, some are 20-30 seconds long. Its just a feeling that i am unable to prove (because i dont know how), but when i disable the database, the freeze seems not to happen. Example: i created a dummy rails application to see the development log. the app made some sql-queries, reads and inserts. the log quite often was like: DbTest Load (0.3ms) SELECT * FROM `db_test` WHERE (`db_test`.`id` = 31722) LIMIT 1 SQL (0.1ms) BEGIN DbTest Update (0.3ms) UPDATE `db_test` SET `updated_at` = '2012-07-04 23:32:34' WHERE `id` = 31722 - now the log stands still for 5-60 seconds. SQL (49.1ms) COMMIT - SQL-Update time in the log does not include freeze time Rendering test/index Completed in 96ms (View: 16, DB: 59) | 200 OK [http://localhost:9000/test] Bad part is: this mini-freeze here only happens from time to time as well. note: meanwhile i cannot even upload files via scp. I currently feel like running form bad to worse and back by googling for my server-problem due to immense lack of knowledge regarding server configurations. It still makes me wonder, why those problems even appear, since 250 users a time is not such a high amount, right? So my questions: whats wrong and how to fix? ;) or: what information can i provide to make the situation more clear? can you point at some critical bad configuration-line which i should consider to catch up in the documentation? are there any tools i can run to see some possible bottlenecks? any further advice? (next to: "pay someone who knows what he does" - its a private project, server costs enough already. :)) Thanks for your time and help. Best Regards, Daniel P.S.: i renamed the configfiles to domain.tld since i dont want to have any % more load to the server until its fixed. might be a exaggeratedly thought.. P.P.S: if i asked a complete duplicate question, sorry. my search results seemed to be quite specific in their own way.

• qemu-kvm virtual machine virtio network freeze under load

  - by Rick Koshi

  I'm having a problem with my virtual machines, where the network will freeze under heavy load. I'm using CentOS 6.2 as both host and guest, not using libvirt, just running qemu-kvm directly as follows: /usr/libexec/qemu-kvm \ -drive file=/data2/vm/rb-dev2-www1-vm.img,index=0,media=disk,cache=none,if=virtio \ -boot order=c \ -m 2G \ -smp cores=1,threads=2 \ -vga std \ -name rb-dev2-www1-vm \ -vnc :84,password \ -net nic,vlan=0,macaddr=52:54:20:00:00:54,model=virtio \ -net tap,vlan=0,ifname=tap84,script=/etc/qemu-ifup \ -monitor unix:/var/run/vm/rb-dev2-www1-vm.mon,server,nowait \ -rtc base=utc \ -device piix3-usb-uhci \ -device usb-tablet /etc/qemu-ifup (used by the above command) is a very simple script, containing the following: #!/bin/sh sudo /sbin/ifconfig $1 0.0.0.0 promisc up sudo /usr/sbin/brctl addif br0 $1 sleep 2 And here's the info on br0 and other interfaces: avl-host3 14# brctl show bridge name bridge id STP enabled interfaces br0 8000.180373f5521a no bond0 tap84 virbr0 8000.525400858961 yes virbr0-nic avl-host3 15# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff 3: em2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff 4: em3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:03:73:f5:52:1e brd ff:ff:ff:ff:ff:ff 5: em4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:03:73:f5:52:20 brd ff:ff:ff:ff:ff:ff 6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff inet6 fe80::1a03:73ff:fef5:521a/64 scope link valid_lft forever preferred_lft forever 7: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff inet 172.16.1.46/24 brd 172.16.1.255 scope global br0 inet6 fe80::1a03:73ff:fef5:521a/64 scope link valid_lft forever preferred_lft forever 8: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 52:54:00:85:89:61 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 9: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500 link/ether 52:54:00:85:89:61 brd ff:ff:ff:ff:ff:ff 12: tap84: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500 link/ether ba:e8:9b:2a:ff:48 brd ff:ff:ff:ff:ff:ff inet6 fe80::b8e8:9bff:fe2a:ff48/64 scope link valid_lft forever preferred_lft forever bond0 is a bond of em1 and em2. virbr0 and virbr0-nic are vestigial interfaces left over from CentOS's default installation. They are unused (as far as I know). The guest runs perfectly until I run a large 'rsync', when the network will freeze after some seemingly-random time (usually under a minute). When it freezes, there is no network activity in or out of the guest. I can still connect to the guest's console via vnc, but it is unable to speak out its network interface. Any attempt to 'ping' from the guest gives a "Destination Host Unreachable" error for 3/4 packets and no reply for every fourth packet. Sometimes (perhaps two thirds of the time), I can bring the interface back to life by doing a "service network restart" from the guest's console. If this works (and if I do it before the rsync times out), the rsync will resume. Usually it will freeze again within a minute or two. If I repeat, the rsync will eventually finish, and I presume the machine goes back to waiting for another period of heavy load. Throughout the whole process, there are no console errors or relevant (that I can see) syslog messages on either guest or host machine. If the "service network restart" doesn't work the first time, trying again (and again and again) never seems to work. The command completes normally, with normal output, but the interface stays frozen. However, a soft reboot of the guest machine (without restarting qemu-kvm) always seems to bring it back. I am aware of the "lowest mac address" assignment problem, where the bridge takes on the mac address of the slave interface with the lowest mac address. This causes temporary network freezes, but is definitely not what's happening for me. My freezes are permanent until manual intervention, and you can see from the 'ip addr show' output above that the mac address being used by br0 is that of the physical ethernet. There are no other virtual machines running on the host. I've verified that each virtual machine on the subnet has its own unique mac address. I have rebuilt the guest machine several times, and I have tried this on three different host machines (identical hardware, built identically). Oddly, I do have one virtual host (the second of this series) which never seemed to have a problem. It never had its network freeze when it was running the same rsync during its build. It's particularly odd because it was the second build. The first, on a different host, did have the freezing problem, but the second did not. I assumed at the time that I had done something wrong with the first build, and that the problem was resolved. Unfortunately, the problem reappeared when I built the third VM. Also unfortunately, I can't do many tests with the working VM, as it's now in production use, and I'm hoping I can find the cause of this issue before that machine starts having problems. It's possible that I just got really lucky while running the rsync on the working machine, and that one time it didn't freeze. Of course it's possible that I somehow changed the build scripts without realizing it and re-broke something, but I can't find any such thing. In any case, I'm hoping someone has some idea what could cause this. Addendum: Preliminary tests suggest that I don't have the problem if I substitute e1000 for virtio in the first -net flag to qemu-kvm. I don't consider this a solution, but it is suitable for a stopgap. Has anyone else had (or better yet, solved) this problem with the virtio network driver?

• Bacula & Multiple Tape Devices, and so on

  - by Tom O'Connor

  Bacula won't make use of 2 tape devices simultaneously. (Search for #-#-# for the TL;DR) A little background, perhaps. In the process of trying to get a decent working backup solution (backing up 20TB ain't cheap, or easy) at $dayjob, we bought a bunch of things to make it work. Firstly, there's a Spectra Logic T50e autochanger, 40 slots of LTO5 goodness, and that robot's got a pair of IBM HH5 Ultrium LTO5 drives, connected via FibreChannel Arbitrated Loop to our backup server. There's the backup server.. A Dell R715 with 2x 16 core AMD 62xx CPUs, and 32GB of RAM. Yummy. That server's got 2 Emulex FCe-12000E cards, and an Intel X520-SR dual port 10GE NIC. We were also sold Commvault Backup (non-NDMP). Here's where it gets really complicated. Spectra Logic and Commvault both sent respective engineers, who set up the library and the software. Commvault was running fine, in so far as the controller was working fine. The Dell server has Ubuntu 12.04 server, and runs the MediaAgent for CommVault, and mounts our BlueArc NAS as NFS to a few mountpoints, like /home, and some stuff in /mnt. When backing up from the NFS mountpoints, we were seeing ~= 290GB/hr throughput. That's CRAP, considering we've got 20-odd TB to get through, in a <48 hour backup window. The rated maximum on the BlueArc is 700MB/s (2460GB/hr), the rated maximum write speed on the tape devices is 140MB/s, per drive, so that's 492GB/hr (or double it, for the total throughput). So, the next step was to benchmark NFS performance with IOzone, and it turns out that we get epic write performance (across 20 threads), and it's like 1.5-2.5TB/hr write, but read performance is fecking hopeless. I couldn't ever get higher than 343GB/hr maximum. So let's assume that the 343GB/hr is a theoretical maximum for read performance on the NAS, then we should in theory be able to get that performance out of a) CommVault, and b) any other backup agent. Not the case. Commvault seems to only ever give me 200-250GB/hr throughput, and out of experimentation, I installed Bacula to see what the state of play there is. If, for example, Bacula gave consistently better performance and speeds than Commvault, then we'd be able to say "**$.$ Refunds Plz $.$**" #-#-# Alas, I found a different problem with Bacula. Commvault seems pretty happy to read from one part of the mountpoint with one thread, and stream that to a Tape device, whilst reading from some other directory with the other thread, and writing to the 2nd drive in the autochanger. I can't for the life of me get Bacula to mount and write to two tape drives simultaneously. Things I've tried: Setting Maximum Concurrent Jobs = 20 in the Director, File and Storage Daemons Setting Prefer Mounted Volumes = no in the Job Definition Setting multiple devices in the Autochanger resource. Documentation seems to be very single-drive centric, and we feel a little like we've strapped a rocket to a hamster, with this one. The majority of example Bacula configurations are for DDS4 drives, manual tape swapping, and FreeBSD or IRIX systems. I should probably add that I'm not too bothered if this isn't possible, but I'd be surprised. I basically want to use Bacula as proof to stick it to the software vendors that they're overpriced ;) I read somewhere that @KyleBrandt has done something similar with a modern Tape solution..

• Problem using a public key when connecting to a SSH server running on Cygwin

  - by Deleted

  We have installed Cygwin on a Windows Server 2008 Standard server and it working pretty well. Unfortunately we still have a big problem. We want to connect using a public key through SSH which doesn't work. It always falls back to using password login. We have appended our public key to ~/.ssh/authorized_keys on the server and we have our private and public key in ~/.ssh/id_dsa respective ~/.ssh/id_dsa.pub on the client. When debugging the SSH login session we see that the key is offered by the server apparently rejects it by some unknown reason. The SSH output when connecting from an Ubuntu 9.10 desktop with debug information enabled: $ ssh -v 192.168.10.11 OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading

• Varnish default.vcl grace period

  - by Vladimir

• Why is Windows Update trying to install an update I don't need?

  - by Oliver Salzburg

  I have a Windows 7 system that currently has a single update pending: Windows Internet Explorer 9 for Windows 7 for x64-based Systems If I try to install the update, Windows Update will: Create a restore point Fail with the error: Code 9C48 Windows Update encountered an error. The event log for the event reads: Installation Failure: Windows failed to install the following update with error 0x80070643: Windows Internet Explorer 9 for Windows 7 for x64-based Systems. If you search the web for that error, there are many other people with the exact same issue. Sadly, I am unable to apply the proposed solutions to my case, because I just installed this system. There is nothing on it, except Windows 7. I installed the system and ran through the updates. I also did the exact same process with this machine several times over the past few days due to a long-term test we just started. I didn't have any problems with any Windows Update on the previous installation runs and I know I didn't do anything different this time because I followed the installation procedures instructions which are to be used during the test. How did this happen and how do I solve it? Further Investigation So, as I always like to do, I ran the update again while running Process Monitor and dug up further details. WindowsUpdate.log First of all, there is a Windows Update log file located at C:\Windows\WindowsUpdate.log which I didn't know about. But I fail to see any significant entry in it, maybe you're more lucky: 2012-04-10 22:46:58:017 956 728 AU AU received approval from Ux for 1 updates 2012-04-10 22:46:58:017 956 728 AU AU setting pending client directive to 'Progress Ux' 2012-04-10 22:46:58:095 956 728 AU BeginInteractiveInstall invoked for Download 2012-04-10 22:46:58:095 956 728 AU Auto-approving update for download, updateId = {B33ACEC1-3265-4D01-9C37-AC0892E95ED9}.100, ForUx=1, IsOwnerUx=1, HasDeadline=0, IsMinor=0 2012-04-10 22:46:58:095 956 728 AU Auto-approved 1 update(s) for download (for Ux) 2012-04-10 22:46:58:110 956 728 AU UpdateDownloadProperties: 0 download(s) are still in progress. 2012-04-10 22:46:58:110 956 728 AU ############# 2012-04-10 22:46:58:110 956 728 AU ## START ## AU: Download updates 2012-04-10 22:46:58:110 956 728 AU ######### 2012-04-10 22:46:58:110 956 728 AU # Approved updates = 1 2012-04-10 22:46:58:110 956 728 AU AU initiated download, updateId = {B33ACEC1-3265-4D01-9C37-AC0892E95ED9}.100, callId = {35DF928B-B428-4BAC-8C63-55295967EFBB} 2012-04-10 22:46:58:110 956 728 AU Setting AU scheduled install time to 2012-04-11 01:00:00 2012-04-10 22:46:58:110 956 728 AU Successfully wrote event for AU health state:0 2012-04-10 22:46:58:110 956 728 AU Currently showing Progress UX client -

• tmux: Suddenly, cannot horizontally split

  - by A__A__0

  As root, using a reasonably default .profile and .shrc and an empty tmux.conf, I am unable to split the window horizontally. There are a number of cases to consider so I'll list them clearly. Using the keybinding + empty configuration: nothing happens Using the keybinding + my configuration: a bell is generated, nothing else; occasionally, the split will appear and disappear immediately

root's .profile and .shrc, tmux works perfectly. Occasionally (twice out of the 50 or so times I've tested it), the splitting will work fine once in a session. (This happened for example when I ran ktrace on tmux, which I can also post) To explain the 'suddenly' part of the title: when I started my newly updated mysql56-server, tmux immediately exited and lost the session. Recently I changed architectures, from FreeBSD 10.0 i386 to amd64, and I am still working through shared library incompatibilities. I suspect that this could be involved, but I can't imagine how an incompatibility of this sort could result in such a specific, isolated failure.

• How mod_cache working with "must-revalidate" and "max-age"?

  - by Dmitriy Sosunov

  Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

Is't right? Let's check it:) Within 30 sec, the Google Chrome didn't perform any requests to the origin server to revalidate a request and has return the response from local cache. When max-age is expired, the Google Chrome perform a request to revalidate: GET http://origin.lo/testpage HTTP/1.1 Host: origin.lo Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Accept: application/xml If-None-Match: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 and response: HTTP/1.1 304 Not Modified Cache-Control: must-revalidate, proxy-revalidate, max-age=30 ETag: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Sun, 04 Nov 2012 10:16:20 GMT As you can see, all works as expected.

N.B. Apache 2.4.3 Thanks, I would be grateful for any help.

• Problem using a public key when connecting to a SSH server running on Cygwin

  - by binary255

  We have installed Cygwin on a Windows Server 2008 Standard server and it working pretty well. Unfortunately we still have a big problem. We want to connect using a public key through SSH which doesn't work. It always falls back to using password login. We have appended our public key to ~/.ssh/authorized_keys on the server and we have our private and public key in ~/.ssh/id_dsa respective ~/.ssh/id_dsa.pub on the client. When debugging the SSH login session we see that the key is offered by the server apparently rejects it by some unknown reason. The SSH output when connecting from an Ubuntu 9.10 desktop with debug information enabled: $ ssh -v 192.168.10.11 OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading

• Cisco ASA: Allowing and Denying VPN Access based on membership to an AD group

  - by milkandtang

  I have a Cisco ASA 5505 connecting to an Active Directory server for VPN authentication. Usually we'd restrict this to a particular OU, but in this case users which need access are spread across multiple OUs. So, I'd like to use a group to specify which users have remote access. I've created the group and added the users, but I'm having trouble figuring out how to deny users which aren't in that group. Right now, if someone connects they get assigned the correct group policy "companynamera" if they are in that group, so the LDAP mapping is working. However, users who are not in that group still authenticate fine, and their group policy becomes the LDAP path of their first group, i.e. CN=Domain Users,CN=Users,DC=example,DC=com, and then are still allowed access. How do I add a filter so that I can map everything that isn't "companynamera" to no access? Config I'm using (with some stuff such as ACLs and mappings removed, since they are just noise here): gateway# show run : Saved : ASA Version 8.2(1) ! hostname gateway domain-name corp.company-name.com enable password gDZcqZ.aUC9ML0jK encrypted passwd gDZcqZ.aUC9ML0jK encrypted names name 192.168.0.2 dc5 description FTP Server name 192.168.0.5 dc2 description Everything server name 192.168.0.6 dc4 description File Server name 192.168.0.7 ts1 description Light Use Terminal Server name 192.168.0.8 ts2 description Heavy Use Terminal Server name 4.4.4.82 primary-frontier name 5.5.5.26 primary-eschelon name 172.21.18.5 dmz1 description Kerio Mail Server and FTP Server name 4.4.4.84 ts-frontier name 4.4.4.85 vpn-frontier name 5.5.5.28 ts-eschelon name 5.5.5.29 vpn-eschelon name 5.5.5.27 email-eschelon name 4.4.4.83 guest-frontier name 4.4.4.86 email-frontier dns-guard !

• CentOS Client - Unable to Establish iSCSI connection with multiple interfaces on the initiator

  - by slashdot

  So after upgrading to CentOS 6.2, I am seemingly no longer able to login into my iSCSI targets. I have multiple interfaces on different subnets on the system, and I first thought that it had to do with the fact that I may not be binding correct interfaces, which seems to be the case when looking at netstat, as this is clearly wrong: [root]? netstat -na|grep .90 tcp 0 1 10.10.100.60:42354 10.10.8.90:3260 SYN_SENT tcp 0 1 10.10.100.60:40777 10.10.9.90:3260 SYN_SENT I then went ahead and disabled all but one interface, and so as a result netstat appears to be correct, but the issue with login remains. I am positive that the target never sees a packet, because I see nothing by SYN_SENT. I know the problem is on my client, because the target is servicing multiple systems, none of which are CentOS 6.2. At this point I am pretty confident that some things changed between CentOS 6.0/6.1 and 6.2. So, if anyone have any thoughts, or ran into this, I would very much like to hear your thoughts.

I went a few weeks back and grabbed a snapshot of this system from before upgrading to 6.2. I spun up a new system from the snapshot, and reconfigured interface info and host keys, as well as iSCSI initiator and iscsi interface info to match new MACs. Changed nothing else. Then, I attempted to connect to my targets, and no issues at all. I cannot say that this was unexpected. I then went ahead and compared sysctl settings from both systems and there were differences after the upgrade, but nothing seemingly relevant to iSCSI or IP that could contribute to this. I also noticed that by default now two sessions per connection were enabled after the upgrade, but I changed it back to 1 session in /etc/iscsi/iscsid.conf. On the problematic system we can see that source interface is seemingly wrong, but even when I disable the 10.10.100 interface, problems persist. So, while this may be relevant, I could not validate it for certain. Needless to say, further research is necessary. Something is clearly different between releases. Working system is on 6.1, and non-working is 6.2. ::Working System:: tcp 0 0 10.10.8.210:39566 10.10.8.90:3260 ESTABLISHED tcp 0 0 10.10.9.210:46518 10.10.9.90:3260 ESTABLISHED [root]? ip route show 10.10.8.0/24 dev eth2.6 proto kernel scope link src 10.10.8.210 10.10.9.0/24 dev eth3.7 proto kernel scope link src 10.10.9.210 10.10.100.0/22 dev eth0 proto kernel scope link src 10.10.100.210 169.254.0.0/16 dev eth0 scope link metric 1002 169.254.0.0/16 dev eth2.6 scope link metric 1006 169.254.0.0/16 dev eth3.7 scope link metric 1007 default via 10.10.100.1 dev eth0 ::Non-working System:: tcp 0 1 10.10.100.60:44737 10.10.9.90:3260 SYN_SENT tcp 0 1 10.10.100.60:55479 10.10.8.90:3260 SYN_SENT [root]? ip route show 10.10.8.0/24 dev eth2.6 proto kernel scope link src 10.10.8.60 10.10.9.0/24 dev eth3.7 proto kernel scope link src 10.10.9.60 10.10.100.0/22 dev eth0 proto kernel scope link src 10.10.100.60 169.254.0.0/16 dev eth0 scope link metric 1002 169.254.0.0/16 dev eth2.6 scope link metric 1006 169.254.0.0/16 dev eth3.7 scope link metric 1007 default via 10.10.100.1 dev eth0 And the result is still same: [root]? iscsiadm: Could not login to [iface: sw-iscsi-0, target: iqn.2011-12.dom.homer:01:lab-centos-servers-00001, portal: 10.10.8.90,3260]. iscsiadm: initiator reported error (8 - connection timed out) iscsiadm: Could not login to [iface: sw-iscsi-1, target: iqn.2011-12.dom.homer:02:lab-centos-servers-00001, portal: 10.10.9.90,3260]. iscsiadm: initiator reported error (8 - connection timed out) iscsiadm: Could not log into all portals Update 01/08/2012: I believe I have been able to figure out the answer to my issue. It is quite obscure and I doubt this will happen to anyone else any time soon. It turns out that setting iface.iscsi_ifacename and iface.hwaddress in the interfaces configuration file is not legal. When one manually adds an iscsi target, such as below, all settings from the interface config file are copied into the node config file, that gets created by the below command. Result is parameters iface.iscsi_ifacename and iface.hwaddress together in the same config file. These parameters are seemingly mutually exclusive, which does not exactly make sense, or there is perhaps an oversight in the codepath. Perhaps I will investigate further. # iscsiadm -m node --op new -T iqn.2011-12.dom.homer:01:lab-centos-servers-00001 -p 10.10.8.90,3260,2 -I sw-iscsi-0 # iscsiadm -m node --op new -T iqn.2011-12.dom.homer:02:lab-centos-servers-00001 -p 10.10.9.90,3260,2 -I sw-iscsi-1 Notice, below I commented out iface.hwaddress and iface.ipaddress, after which I re-added targets, with same command as above. All works just fine. [root]? cat * # BEGIN RECORD 2.0-872.33.el6 iface.iscsi_ifacename = sw-iscsi-0 iface.net_ifacename = eth2.6 #iface.hwaddress = XX:XX:XX:XX:XX:XX #iface.ipaddress = 10.10.8.60 iface.transport_name = tcp iface.vlan_id = 6 iface.vlan_priority = 0 iface.iface_num = 0 iface.mtu = 0 iface.port = 0 # END RECORD # BEGIN RECORD 2.0-872.33.el6 iface.iscsi_ifacename = sw-iscsi-1 iface.net_ifacename = eth3.7 #iface.hwaddress = XX:XX:XX:XX:XX:XX #iface.ipaddress = 10.10.9.60 iface.transport_name = tcp iface.vlan_id = 7 iface.vlan_priority = 0 iface.iface_num = 0 iface.mtu = 0 iface.port = 0 # END RECORD Again, chances of this happening to someone else are slim to none, so likely waste of time typing this up. But, if someone does encounter this issue, I hope this post will help.

• Troubleshooting latency spikes on ESXi NFS datastores

  - by exo_cw

  I'm experiencing fsync latencies of around five seconds on NFS datastores in ESXi, triggered by certain VMs. I suspect this might be caused by VMs using NCQ/TCQ, as this does not happen with virtual IDE drives. This can be reproduced using fsync-tester (by Ted Ts'o) and ioping. For example using a Grml live system with a 8GB disk: Linux 2.6.33-grml64: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 5.0391 fsync time: 5.0438 fsync time: 5.0300 fsync time: 0.0231 fsync time: 0.0243 fsync time: 5.0382 fsync time: 5.0400 [... goes on like this ...] That is 5 seconds, not milliseconds. This is even creating IO-latencies on a different VM running on the same host and datastore: root@grml /mnt/sda/ioping-0.5 # ./ioping -i 0.3 -p 20 . 4096 bytes from . (reiserfs /dev/sda): request=1 time=7.2 ms 4096 bytes from . (reiserfs /dev/sda): request=2 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=3 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=4 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=5 time=4809.0 ms 4096 bytes from . (reiserfs /dev/sda): request=6 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=7 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=8 time=1.1 ms 4096 bytes from . (reiserfs /dev/sda): request=9 time=1.3 ms 4096 bytes from . (reiserfs /dev/sda): request=10 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=11 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=12 time=4950.0 ms When I move the first VM to local storage it looks perfectly normal: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 0.0191 fsync time: 0.0201 fsync time: 0.0203 fsync time: 0.0206 fsync time: 0.0192 fsync time: 0.0231 fsync time: 0.0201 [... tried that for one hour: no spike ...] Things I've tried that made no difference: Tested several ESXi Builds: 381591, 348481, 260247 Tested on different hardware, different Intel and AMD boxes Tested with different NFS servers, all show the same behavior: OpenIndiana b147 (ZFS sync always or disabled: no difference) OpenIndiana b148 (ZFS sync always or disabled: no difference) Linux 2.6.32 (sync or async: no difference) It makes no difference if the NFS server is on the same machine (as a virtual storage appliance) or on a different host Guest OS tested, showing problems: Windows 7 64 Bit (using CrystalDiskMark, latency spikes happen mostly during preparing phase) Linux 2.6.32 (fsync-tester + ioping) Linux 2.6.38 (fsync-tester + ioping) I could not reproduce this problem on Linux 2.6.18 VMs. Another workaround is to use virtual IDE disks (vs SCSI/SAS), but that is limiting performance and the number of drives per VM. Update 2011-06-30: The latency spikes seem to happen more often if the application writes in multiple small blocks before fsync. For example fsync-tester does this (strace output): pwrite(3, "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 1048576, 0) = 1048576 fsync(3) = 0 ioping does this while preparing the file: [lots of pwrites] pwrite(3, "********************************"..., 4096, 1036288) = 4096 pwrite(3, "********************************"..., 4096, 1040384) = 4096 pwrite(3, "********************************"..., 4096, 1044480) = 4096 fsync(3) = 0 The setup phase of ioping almost always hangs, while fsync-tester sometimes works fine. Is someone capable of updating fsync-tester to write multiple small blocks? My C skills suck ;) Update 2011-07-02: This problem does not occur with iSCSI. I tried this with the OpenIndiana COMSTAR iSCSI server. But iSCSI does not give you easy access to the VMDK files so you can move them between hosts with snapshots and rsync. Update 2011-07-06: This is part of a wireshark capture, captured by a third VM on the same vSwitch. This all happens on the same host, no physical network involved. I've started ioping around time 20. There were no packets sent until the five second delay was over: No. Time Source Destination Protocol Info 1082 16.164096 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1085), FH:0x3eb56466 Offset:0 Len:84 FILE_SYNC 1083 16.164112 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1086), FH:0x3eb56f66 Offset:0 Len:84 FILE_SYNC 1084 16.166060 192.168.250.20 192.168.250.10 TCP nfs > iclcnet-locate [ACK] Seq=445 Ack=1057 Win=32806 Len=0 TSV=432016 TSER=769110 1085 16.167678 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1082) Len:84 FILE_SYNC 1086 16.168280 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1083) Len:84 FILE_SYNC 1087 16.168417 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1057 Ack=773 Win=4163 Len=0 TSV=769110 TSER=432016 1088 23.163028 192.168.250.10 192.168.250.20 NFS V3 GETATTR Call (Reply In 1089), FH:0x0bb04963 1089 23.164541 192.168.250.20 192.168.250.10 NFS V3 GETATTR Reply (Call In 1088) Directory mode:0777 uid:0 gid:0 1090 23.274252 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1185 Ack=889 Win=4163 Len=0 TSV=769821 TSER=432716 1091 24.924188 192.168.250.10 192.168.250.20 RPC Continuation 1092 24.924210 192.168.250.10 192.168.250.20 RPC Continuation 1093 24.924216 192.168.250.10 192.168.250.20 RPC Continuation 1094 24.924225 192.168.250.10 192.168.250.20 RPC Continuation 1095 24.924555 192.168.250.20 192.168.250.10 TCP nfs > iclcnet_svinfo [ACK] Seq=6893 Ack=1118613 Win=32625 Len=0 TSV=432892 TSER=769986 1096 24.924626 192.168.250.10 192.168.250.20 RPC Continuation 1097 24.924635 192.168.250.10 192.168.250.20 RPC Continuation 1098 24.924643 192.168.250.10 192.168.250.20 RPC Continuation 1099 24.924649 192.168.250.10 192.168.250.20 RPC Continuation 1100 24.924653 192.168.250.10 192.168.250.20 RPC Continuation 2nd Update 2011-07-06: There seems to be some influence from TCP window sizes. I was not able to reproduce this problem using FreeNAS (based on FreeBSD) as a NFS server. The wireshark captures showed TCP window updates to 29127 bytes in regular intervals. I did not see them with OpenIndiana, which uses larger window sizes by default. I can no longer reproduce this problem if I set the following options in OpenIndiana and restart the NFS server: ndd -set /dev/tcp tcp_recv_hiwat 8192 # default is 128000 ndd -set /dev/tcp tcp_max_buf 1048575 # default is 1048576 But this kills performance: Writing from /dev/zero to a file with dd_rescue goes from 170MB/s to 80MB/s. Update 2011-07-07: I've uploaded this tcpdump capture (can be analyzed with wireshark). In this case 192.168.250.2 is the NFS server (OpenIndiana b148) and 192.168.250.10 is the ESXi host. Things I've tested during this capture: Started "ioping -w 5 -i 0.2 ." at time 30, 5 second hang in setup, completed at time 40. Started "ioping -w 5 -i 0.2 ." at time 60, 5 second hang in setup, completed at time 70. Started "fsync-tester" at time 90, with the following output, stopped at time 120: fsync time: 0.0248 fsync time: 5.0197 fsync time: 5.0287 fsync time: 5.0242 fsync time: 5.0225 fsync time: 0.0209 2nd Update 2011-07-07: Tested another NFS server VM, this time NexentaStor 3.0.5 community edition: Shows the same problems. Update 2011-07-31: I can also reproduce this problem on the new ESXi build 4.1.0.433742.
