  • I am unable to connect to my netbook from any machine on my network until the netbook has pinged it

    - by Samuel Husky
    I have a rather strange issue with my netbook on my local network. When trying to connect to it in any way from a remote system it does not appear to find it. However if I get the netbook to ping the machine trying to connect it mystically appears to work. Below is the ping test from my main PC to the netbook.

  • Help debugging Sendmail/Mailman configuration issue

    - by inxilpro
    Hi folks, I'm trying to configure a server with Sendmail and Mailman. I've been getting "Broken pipe" errors for a while, and have slowly been debugging. I fixed some permission issues, and changed the user that Mailman expects to be called from, among other things. Finally, I'd gone through everything I could think of, so I added a new test to see if it's the Mailman script or Sendmail that's causing the problem. Here's the error I'm getting now (stripped of timestamps and identifying information): <-- MAIL FROM:[email protected] Authentication-Warning: xxxxx.org: xxxxxxxxxxxxxx.net [xx.xx.xxx.xxx] didn't use HELO protocol --- 250 2.1.0 [email protected]...

  • Can't get virtual desktops to show up on RDWeb for Server 2012 R2

    - by Scott Chamberlain
    I built a test lab using the Windows Server 2012 R2 Preview. The initial test lab has the following configuration (I have replaced our name with "OurCompanyName" because I would like it if Google searches for our name did not cause people to come to this site, please do the same in any responses) Physical hardware running Windows Server 2012 R2 Preview full GUI, acting as Hyper-V host (joined to the test domain as testVwHost.testVw.OurCompanyName.com) with the following VM's running on it VM running 2012 R2 Core acting as domain controller for the forest testVw.OurCompanyName.com (testDC.testVw.OurCompanyName.com) VM running 2012 R2 Core with nothing running on it joined to the test domain as testIIS.testVw.OurCompanyName.com A clean install of Windows 7, all that was done to it was all windows updates where loaded and sysprep /generalize /oobe /shutdown /mode:vm was run on it A clean install of Windows 8, all that was done to it was all windows updates where loaded and sysprep /generalize /oobe /shutdown /mode:vm was run on it I then ran "Add Roles and Features" from testVwHost and chose the "Remote Desktop Services Installation", "Standard Deployment", "Virtual machine-based desktop deployment". I choose testIIS for the roles "RD Connection Broker" and "RD Web Access" and testVwHost as "RD Virtualization Host" The Install of the roles went fine, I then went to Remote Desktop Services in server manager and wet to setup Deployment Properties. I set the certificate for all 3 roles to our certificate signed by a CA for *.OurCompanyName.com. I then created a new Virtual Desktop Collection for Windows 7 and Windows 8 and both where created without issue. On the Windows 7 pool I added RemoteApp to launch WordPad, For windows 8 I did not add any RemoteApp programs. Everything now appears to be fine from a setup perspective however if I go to https://testIIS.testVw.OurCompanyName.com/RDWeb and log in as the use Administrator (or any orher user) I don't see the virtual desktops I created nor the RemoteApp publishing of WordPad. I tried adding a licensing server, using testDC as the server but that made no difference. What step did I miss in setting this up that is causing this not to show up on RDWeb? If any additional information is needed pleas let me know. I have tried every possible thing I can think of and I am just groping around in the dark now. The virtual machines running on testVwHost The configuration screen for RD Services The Windows 7 Pool The Windows 8 Pool This is logged in as testVw\Administrator

  • Event ID 9331 MSExchangeSA & Event ID 9335 MSExchangeSA

    - by George
    I get this two Exchange 2010 Global Address book related event IDs: Event ID 9331 MSExchangeSA OABGen encountered error 80004005 (internal ID 50101f1) accessing the public folder database while generating the offline address list for address list '/'. -\Default Offline Address List and Event ID 9335 MSExchangeSA OABGen encountered error 80004005 while cleaning the offline address list public folders under /o=xxxxx xxxx/cn=addrlists/cn=oabs/cn=Default Offline Address List. Please make sure the public folder database is mounted and replicas exist of the offline address list folders. No offline address lists have been generated. Please check the event log for more information. -\Default Offline Address List It is Exchange 2010 SP2 sitting on Windows 2008 enterprise edition. Essentially the issue is that the global address book is not being updated on Outlook clients. We are using Outlook 2007 and 2010. So far I have tried running the following command: Update-FileDistributionService -Identity ExchangeServer -Type "OAB" And I tried this solution as well: 1) Make sure the Microsoft Exchange System Attendant is running. It will be set to start automatically by default, but it doesn't. This is a known issue. Start this service manually. When running, you will not get an error when trying to update the GAL. 2) "Apply" any changes made to any address lists before the GAL will update Outlook properly. In Organization Configuration - Mailbox in EMC, view the properties of the Default Global Address Book in the Offline Address Book tab. In the properties window, select the Address Lists tab. This shows which address lists makes up the GAL. 3) Close the properties window and select the Address Lists tab in the Organization Configuration - Mailbox. Right-click each address list used by the Def GAL and click "Apply" (make sure the "Immediately" radio button is checked). 4) Last, go back to the Offline Address Book tab, right-click the GAL and select "Update". After a few send/receives in the Outlook clients, their Glogal Address List should update to show the latest changes. Neither one of those solutions helped. So I am not really sure what to do here. Also, I am aware of changing registry on each local computers, but it would be close to impossible as we have 8 offices in 3 different countries. Any suggestions? EDIT 7.XII.2012 @ 10.35 I forgot to mention that we did rebuild the address book and that didn't help.

  • Why is mount -a not mounting fuse drive properly when executed remotely (via Fabric)?

    - by Jim D
    This is a weird bug and I'm not sure where it's coming from. Here's a quick run down of what I'm doing. I'm trying to mount a FUSE drive to an Amazon EC2 instance running Ubuntu 10.10 using s3fs (FUSE over Amazon). s3fs is compiled from source according to the instructions etc. I've also added an entry to /etc/fstab so that the drive mounts on boot. Here's what /etc/fstab looks like: # /etc/fstab: static file system information. # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 LABEL=uec-rootfs / ext4 defaults 0 0 /dev/sda2 /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 /dev/sda3 none swap sw,comment=cloudconfig 0 0 s3fs#mybucket /mnt/s3/mybucket fuse default_acl=public-read,use_cache=/tmp,allow_other 0 0 So the good news is that this works fine. On reboot the connection mounts correctly. I can also do: $ sudo umount /mnt/s3/mybucket $ sudo mount -a $ mountpoint /mnt/s3/mybucket /mnt/s3/mybucket is a mountpoint Great, right? Well here's the problem. I'm using Fabric to automate the process of building and managing this instance. I noticed I was getting this error message when using Fabric to build s3fs and set up the mount process: mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected I isolated it down the the problem and built a fabric task that reproduces the problem: def remount_s3fs(): sudo("mount -a") Which does: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: mount -a [And yes, I was sure to unmount it before running this task.] When I check the mount using mountpoint I get: $ mountpoint /mnt/s3/mybucket mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected Done. But if I run sudo mount -a at the command line, it works. Hrm. Here is that fab task output again, this time in full debug mode: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a" Again, I get that transport endpoint not connected error. I've also tried copying and pasting the exact command run into my ssh session (i.e. sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a") and it works fine. So...that's my problem. Any ideas?

  • php-fpm or nginx: bad gateway

    - by John Tate
    I'm getting a bad gateway error all the sudden for a site. I didn't change the configuration for the site, I just added a new server config where I put them under /etc/nginx/servers and it stopped working. The new server works, and there is no conflict between the php-fpm listen addresses. server { listen 80; server_name obfuscated.onion; location = / { root /var/www/sites/obfuse; index index.php; } location / { root /var/www/sites/obfuse; index index.php; if (!-f $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } if (!-d $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } } error_page 404 /index.php; location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ { root /var/www/sites/obfuse; access_log off; expires 30d; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/sites/obfuse$fastcgi_script_name; 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_param PATH_INFO $fastcgi_script_name; include fastcgi_params; } } There is nothing unusual in php-fpm's log even when I raised the level to debug.

  • Anyone else experiencing high rates of Linux server crashes during a leap second day?

    - by Bron Gondwana
    POSTMORTEM Anticlimax: only thing that died was my VPN (openvpn) link to the cluster, so there was an exciting few seconds while it re-established. Everything else was fine. Starting back ntp everywhere. If you look at Marco's blog at http://my.opera.com/marcomarongiu/blog/2012/06/01/an-humble-attempt-to-work-around-the-leap-second - he has a solution for phasing the time change over 24 hours using ntpd -x to avoid the 1 second skip. Give that a go if it matters to you. For the systems I run, the jump isn't a problem. Just today, Sat June 30th - starting soon after the start of the day GMT. We've had a handful of blades in different datacentres as managed by different teams all go dark - not responding to pings, screen blank. They're all running Debian Squeeze - with everything from stock kernel to custom 3.2.21 builds. Most are Dell M610 blades, but I've also just lost a Dell R510 and other departments have lost machines from other vendors too. There was also an older IBM x3550 which crashed and which I thought might be unrelated, but now I'm wondering. The one crash which I did get a screen dump from said: [3161000.864001] BUG: spinlock lockup on CPU#1, ntpd/3358 [3161000.864001] lock: ffff88083fc0d740, .magic: dead4ead, .owner: imapd/24737, .owner_cpu: 0 Unfortunately the blades all supposedly had kdump configured, but they died so hard that kdump didn't trigger - and they had console blanking turned on. I've disabled console blanking now, so fingers crossed I'll have more information after the next crash. Just want to know if it's a common thread or "just us". It's really odd that they're different units in different datacentres bought at different times and run by different admins (I run the FastMail.FM ones)... and now even different vendor hardware. Most of the machines which crashed had been up for weeks/months and were running 3.1 or 3.2 series kernels. The most recent crash was a machine which had only been up about 6 hours running 3.2.21. THE WORKAROUND Ok people, here's how I worked around it. disabled ntp: /etc/init.d/ntp stop created http://linux.brong.fastmail.fm/2012-06-30/fixtime.pl (code stolen from Marco, see blog posts in comments) ran fixtime.pl without an argument to see that there was a leap second set ran fixtime.pl with an argument to remove the leap second NOTE: depends on adjtimex. I've put a copy of the squeeze adjtimex binary at http://linux.brong.fastmail.fm/2012-06-30/adjtimex - it will run without dependencies on a squeeze 64 bit system. If you put it in the same directory as fixtime.pl, it will be used if the system one isn't present. Obviously if you don't have squeeze 64 bit... find your own. I'm going to start ntp again tomorrow. As an anonymous user suggested - an alternative to running adjtimex is to just set the time yourself, which will presumably also clear the leapsecond counter.

  • Pxe net install Centos with Static IP

    I seem to be unable to perform a kickstart installation of centos5.8 with a netinstall. It correctly gets into the text installer, but keeps sending out a request for the dhcp server and failing.

Perhaps there is an error in of my files? My dhcp server is set to ignore client-updates, and is set to only works with one mac address whilst testing.

  • Suspicious process running under user named

    - by Amit
    I get a lot of emails reporting this and I want this issue to auto correct itself. These process are run by my server and are a result of updates, session deletion and other legitimate session handling reported as false positives. Here's a sample report: Time: Sat Oct 20 00:00:03 2012 -0400 PID: 20077 Account: named Uptime: 326117 seconds Executable: /usr/sbin/nsd\00507d27e9\0053\00\00\00\00\00 (deleted) The file system shows this process is running an executable file that has been deleted. This typically happens when the original file has been replaced by a new file when the application is updated.

  • Postfix flow/hook reference, or high-level overview?

    - by threecheeseopera
    The Postfix MTA consists of several components/services that work together to perform the different stages of delivery and receipt of mail; these include the smtp daemon, the pickup and cleanup processes, the queue manager, the smtp service, pipe/spawn/virtual/rewrite ... and others (including the possibility of custom components). Postfix also provides several types of hooks that allow it to integrate with external software, such as policy servers, filters, bounce handlers, loggers, and authentication mechanisms; these hooks can be connected to different components/stages of the delivery process, and can communicate via (at least) IPC, network, database, several types of flat files, or a predefined protocol (e.g. milter). An old and very limited example of this is shown at this page. My question: Does anyone have access to a resource that describes these hooks, the components/delivery stages that the hook can interact with, and the supported communication methods? Or, more likely, documentation of the various Postfix components and the hooks/methods that they support? For example: Given the requirement "if the recipient primary MX server matches 'shadysmtpd', check the recipient address against a list; if there is a match, terminate the SMTP connection without notice". My software would need to 1) integrate into the proper part of the SMTP process, 2) use some method to perform the address check (TCP map server? regular expressions? mysql?), and 3) implement the required action (connection termination). Additionally, there will probably be several methods to accomplish this, and another requirement would be to find that which best fits (ex: a network server might be faster than a flat-file lookup; or, if a large volume of mail might be affected by this check, it should be performed as early in the mail process as possible). Real-world example: The apolicy policy server (performs checks on addresses according to user-defined rules) is designed as a standalone TCP server that hooks into Postfix inside the smtpd component via the directive 'check_policy_service inet:127.0.0.1:10001' in the 'smtpd_client_restrictions' configuration option. This means that, when Postfix first receives an item of mail to be delivered, it will create a TCP connection to the policy server address:port for the purpose of determining if the client is allowed to send mail from this server (in addition to whatever other restrictions / restriction lookup methods are defined in that option); the proper action will be taken based on the server's response. Notes: 1)The Postfix architecture page describes some of this information in ascii art; what I am hoping for is distilled, condensed, reference material. 2) Please correct me if I am wrong on any level; there is a mountain of material, and I am just one man ;) Thanks!

  • filtering itunes library items by file location

    - by Cawas
    3 answers and unfortunately no solution yet. The Problem I've got way more than 1000 duplicated items in my iTunes Library pointing to a non-existant place (the "where" under "get info" window), along with other duplicated items and other MIAs (Missing In Action). Is there any simple way to just delete all of them and only them? From the library, of course. By that I mean some MIAs are pointing to /Volumes while some are pointing to .../music/Music/... or just .../music/.... I want to delete all pointing to /Volumes as to later I'll recover the rest. Check the image below. Some Background I tried searching for a specific key word on the path and creating smart play list, but with no result. Being able to just sort all library by path would be a perfect solution! I believe old iTunes could do that. PowerTunes can do it (sort by path) but I can't do anything with its list. I would also welcome any program able to handle this, then import and properly export back the iTunes library. Since this seems to just not be clear enough... AppleScript doesn't work That's because AppleScript just can't gather the missing info anywhere in iTunes Library. Maybe we could use AppleScript by opening the XML file, but that's a whole nother issue. Here's a quote from my conversation with Doug the man himself Adams last december: I don't think you do understand. There is no way to get the path to the file of a dead track because iTunes has "forgotten" it. That is, by definition, what a dead track is. Doug On Dec 21, 2010, at 7:08 AM, Caue Rego wrote: yes I understand that and have seem the script. but I'm not looking for the file. just the old broken path reference to it. Sent from my iPhone On 21/12/2010, at 10:00, Doug Adams wrote: You cannot locate missing files of dead tracks because, by definition, a dead track is one that doesn't have any file information. If you look at "Super Remove Dead Tracks", you will notice it looks for tracks that have "missing value" for the location property.

  • Why do some games randomly turn my screen a random solid color?

    - by Emlena.PhD
    When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems. Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120305-1505) System Manufacturer: Gigabyte Technology Co., Ltd.

  • LACP : Cisco ASA 5515 & Switch ProCurve 2920

    - by user979276
    I've two ASAs 5515 connected in failover Active/Stand by (on Gi0/5) My two ASAs are connected to two Switch ProCurve 2920 to have HA if something happens. So I plug something like that (don't pay attention to the arrows) : So one the ASA, I created a Port-Channel like that : interface GigabitEthernet0/0 nameif outside security-level 0 ip address 192.168.1.3 255.255.255.0 standby 192.168.1.4 ! interface GigabitEthernet0/1 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface GigabitEthernet0/2 speed 1000 duplex full channel-group 1 mode passive no nameif no security-level no ip address ! interface Port-channel1.1 vlan 1 nameif inside security-level 100 ip address 192.168.8.1 255.255.255.0 standby 192.168.8.2 ! interface Port-channel1.10 vlan 10 nameif guest security-level 50 ip address 172.16.100.2 255.255.255.224 standby 172.16.100.3 ! interface Port-channel1.16 vlan 16 nameif dmz security-level 50 ip address 192.168.16.1 255.255.255.0 standby 192.168.16.2 On the switch, I created a trunk LACP capable with the port 1 and 2 on each switch, force the speed to 1000 and put the port un full duplex mode. BUT this is not working... I tried many things and I can't make it work. In this configuration, I can't ping anything between my ASA and my Switch (or any object connected). Here what I get on my ASA : Channel group 1 LACP port Admin Oper Port Port Port Flags State Priority Key Key Number State ----------------------------------------------------------------------------- Gi0/2 SP not-bndl 32768 0x1 0x1 0x3 0xc Gi0/1 FP not-bndl 32768 0x1 0x1 0x2 0x6 And on the Switchs : PORT LACP TRUNK PORT LACP LACP NUMB ENABLED GROUP STATUS PARTNER STATUS ----- ------- ----- ------ ------- ------ 1 Active trk1 Broken Yes Failure 2 Active trk1 Broken Yes Failure If I change the Cisco interface to LACP mode On, I can ping the switch from the ASA but nothing other objects conneted on the switch. If I look at the statut of LACP on the switch I see this : PORT LACP TRUNK PORT LACP LACP NUMB ENABLED GROUP STATUS PARTNER STATUS ----- ------- ----- ------ ------- ------ 1 Active trk1 Up No Success 2 Active trk1 Up No Success I don't have any clue on what's going on so If someone have any idea and help me on this, it would be great ! Feel free to ask me anything if you need any more information ! Thanks a lot !

  • Microsoft Office 2003 document (Excel and Word) intermitently, takes 30 seconds to load

    - by Julio Nobre
    I am trying to figure out why a simple .XLS EXCEL workbook is taking, randomly, 30 seconds to open. Before answering: Please, bear mind the following: Problem symptoms Hanging is intermitent and it takes exactly 30 seconds; During hanging there is no cpu or disk activity; It only happens during document load. Every runs smooth after that; Windows Explorer.exe hangs on folder, but all other folders, system and applications are still responsive; There are no consecutive hangings. I have to wait for while to reproduce this behaviour; All samples documents are located on a local drive (C:\BPI); The no document has has macros and have any addins usage; The problem does occurs on others files extensions like .PDF, for example; Office 2003 is being used for several years; The computer is running Windows XP; Computer has several network mapped drives, all addressed to main file server; Recently, main fileserver was replaced by Windows 2011 SBS Standard Edition What I have done so far I have traced machine Explorer.exe, using Process Monitor, added Duration column, and filtered by Duration 1. That's is how I found that hanging was taking exactly 30 seconds. For further information, please refer to Oliver Salzburg tutorial. Using Process Monitor, I have also figured out than five operations were taking most of sample collecting duration. Looking at sample image below, column Operation below you will notice that one single operation was taking 29 seconds; I have tried different documents (.xls and .doc), all of them smaller than 30 KB; I have, temporarily, removed all shortcuts on User Document's folder that were pointing to network drives or shares; I have runned CCleaner to fix registry issues; I made sure that there were no external links on tested workbook or word documents; I have reproduced this behaviour for hours; I have extensivelly researched for hours on the web; Process Monitor's collected and filtered data

  • Looking for Fiddler2 help. connection to gateway refused...just got rid of a virus?

    - by john mackey
    I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed. Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

  • Google Apps For Business, SSO, AD FS 2.0 and AD

    - by Dominique dutra
    We are a small company with 22 people in the office. We had a lot of problems with e-mail in the past so I decided to change over to Google Apps for Business. It is the perfect solution for us, except for one thing: I need to be able to control the access to the mailboxes. Only users inside the office, authenticated to AD, or users authenticated to our VPN can connect to gmail. From what I've read it is possible using the SSO (Single Sign On) solution provided by Google - but i am having some trouble finding consistent information about it. First of all, our infrastructure: Windows Server 2008 R2 Active Directory, one domain only. Kerio Control for QoS and VPN. That's about it on our side. On Google Apps' side, I have one account, and 03 domains that my users use to log in. The main domain has most of the users, but the are a couple of people that login using one of the subdomains. I have a 03 domains because I run mail for 03 companies and wanted all to be in within the same control panel. Well, I found some guides on the internet but none of them cover the AD FS installation part. I've read somewhere that I needed to download AD FS 2.0 directly from Microsoft.com, because the one that came with Windows Server was a old version. I downloaded it (adfsSetup.exe) and tried to install but got an error, saying that I needed a Windows Server 2008 Sp2 for that program. My Windows Server 2008 is R2. I really need some help here, this is very importand, I dont want to have to pay $1000 for a SSO solution when i have an AD set up. Can someone please point me out to the right direction? Where can I find an AD FS 2.0 setup compatible with R2 would be a good start, or the one that came with r2 is already the 2.0 version. After the initial setup, there are some guides on the internet about the Google Apps part. It seems to be really easy. I also tried adding AD FS role, but there are a bunch of options wich I have no idea what means, and I coudn't find any guide covering that on the internet. I dont have a lot of experience with Windows Server, but I have a company wich is certificated and provide us with support. I can ask for their help in the later setup, but I dont think ADFS is a very common thing to deal with.

  • How to recover a MySQL InnoDB table?

    - by Kau-Boy
    When I try to launch the Plesk administration page of you server I get the following error: ERROR: PleskMainDBException MySQL query failed: MySQL server has gone away The MySQL Server is working well. Although it seems that the plesk database is somehow corrupt and any action on this database results in a restart of the mysql process, so even queries to other databases on the same MySQL server will be lost. If I try to connect to the plesk database using phpMyAdmin, I can only see the number of tables, the database had originally. But I am not able to open the tables listing. As soon as I try it, the mysql process crashes again. Trying to connect to the database using ssh works. I can even run a SELECT statement against any table an get a result. I don't know if it is an plesk error or an error of the psa database or even the MySQL server. Can you give me any tips on how to recover the plesk system. Should I try to repair the Plesk installation before. And if so, how can I do it and will all my settings get lost doing it? EDIT: Trying to dump the database, I get the following error: mysqldump: Got error: 2013: Lost connection to MySQL server during query when using LOCK TABLES EDIT: I could find out, that the table 'data_bases' is responsible for the crash of the MySQL server process. But trying to repair it using a REPAIR TABLE statement doesn't work. EDIT: I now dropped the whole database and restored it from a dump. But why I try to recover the data_bases table I get the following error: ERROR 1005 (HY000) at line 24: Can't create table './psa/data_bases.frm' (errno: 121) I am not able to create the table again. Somewhere in the MySQL system there is still some information about this table. I tested the same thing locally. If I just delete the table files and then try to create the table again I get the same error. If I drop the table through MySQL, I can create the table again afterwards. But trying to drop the table using MySQL the whole MySQL system crashed. Is there any way to solve that issue?

It is not just rkhunter, i am not able to install anything.

  • How do large blobs affect SQL delete performance, and how can I mitigate the impact?

    - by Max Pollack
    I'm currently experiencing a strange issue that my understanding of SQL Server doesn't quite mesh with. We use SQL as our file storage for our internal storage service, and our database has about half a million rows in it. Most of the files (86%) are 1mb or under, but even on fresh copies of our database where we simply populate the table with data for the purposes of a test, it appears that rows with large amounts of data stored in a BLOB frequently cause timeouts when our SQL Server is under load. My understanding of how SQL Server deletes rows is that it's a garbage collection process, i.e. the row is marked as a ghost and the row is later deleted by the ghost cleanup process after the changes are copied to the transaction log. This suggests to me that regardless of the size of the data in the blob, row deletion should be close to instantaneous. However when deleting these rows we are definitely experiencing large numbers of timeouts and astoundingly low performance. In our test data set, its files over 30mb that cause this issue. This is an edge case, we don't frequently encounter these, and even though we're looking into SQL filestream as a solution to some of our problems, we're trying to narrow down where these issues are originating from. We ARE performing our deletes inside of a transaction. We're also performing updates to metadata such as file size stats, but these exist in a separate table away from the file data itself. Hierarchy data is stored in the table that contains the file information. Really, in the end it's not so much what we're doing around the deletes that matters, we just can't find any references to low delete performance on rows that contain a large amount of data in a BLOB. We are trying to determine if this is even an avenue worth exploring, or if it has to be one of our processes around the delete that's causing the issue. Are there any situations in which this could occur? Is it common for a database server to come to the point of complete timeouts when many of these deletes are occurring simultaneously? Is there a way to combat this issue if it exists? (cross-posted from StackOverflow )

  • Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

    - by Alexander
    I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

  • windows 2008 R2 TS printer security - can't take owership

    - by Ian
    I have a Windows 2008 R2 server with Terminal server role installed. I'm seeing a problem with an ordinary user who is member of local printer operators group on the server. If the user opens a cmd window using ‘run as administrator’ they can run printmanager.msc without needing to enter their password again. In printmanager they can change the ownership of redirected (easy print) printers without problems. If, from the same cmd window, they use subinacl to try and change the onwership of the queue to themselves they get access denied: >subinacl.exe /printer "_#MyPrinter (2 redirected)" /setowner="MyDom\MyUsr" Elapsed Time: 00 00:00:00 Done: 1, Modified 0, Failed 1, Syntax errors 0 Last Done : _#MyPrinter (2 redirected) Last Failed: _#MyPrinter (2 redirected) - OpenPrinter Error : 5 Access denied so, same context, same action but one works and one doesn't. Any ideas for this odd behaviour? I'm using subinacl x86 on an x64 server as I can't find anything more up to date. I've tried with icacls and others but couldn't get them to do anything with printers. EDIT: added after Gregs comments regarding setacl below If I log into the TS server as Testusr and open Admin Tools Printer Admin (as administrator) and then type mydomain\testusr and the testusr's password, then I can change the ownership of the printer queue and set testusr as the owner. However if I open cmd as administrator and, again, type mydomain\testusr and the users password when I try to change the ownership of my redirected printer I get the following: C:\>setacl -on "Bullzip PDF Printer (12 redireccionado)" -ot prn -actn setowner -ownr n:mydom\testusr WARNING: Privilege 'Back up files and directories' could not be enabled. SetACL's powers are restricted. WARNING: Privilege 'Restore files and directories' could not be enabled. SetACL's powers are restricted. INFORMATION: Processing ACL of: <Bullzip PDF Printer (12 redireccionado)> ERROR: Enabling the privilege SeTakeOwnershipPrivilege failed with: No todos los privilegios o grupos a los que se hace referencia son asignados al llamador. [meaning not all referenced privs or groups are assigned to the caller] SetACL finished with error(s): SetACL error message: A privilege could not be enabled maybe I'm getting something wrong but if the built in windows tool can do it with just membership of the 'print operators' group then setacl should be able to as well, no? However setacl seems to depend on other privileges, which in reality are not required to do this.

  • How much did it cost our competitor to DDoS us at 50 Gbps for two weeks?

    - by MiniQuark
    I know that this question may sound like an invalid serverfault question, but I believe that it's quite valid: the amount of time and effort that a sysadmin should spend on DDoS protection is a direct function of typical DDoS prices. Let me rephrase this: protecting a web site against small attacks is one thing, but resisting 50 Gbps of UDP flood is another and requires time & money. Deciding whether or not to spend that time & money depends on whether such an attack is likely or not, and this in turn depends on how cheap and simple such an attack is for the attacker. So here's the full story: our company has been victim to a massive DDoS attack (over 50 Gbps of UDP traffic, full-time during 2 weeks). We are pretty sure that it's one of our competitors, and we actually know which one, because we were the only two remaining competitors on a very big request for proposal, and the DDoS attack magically stopped the day we won (double hurray, by the way)! These people have proved in the past that they are very dishonest, but we know that they are not technical at all, so we believe that they simply paid for some botnet DDoS service. I would like to know how much these services typically cost, for such a large scale attack. Please do not give any link to such services, I would really hate to give these people any publicity. I understand that a hacker could very well do this for free, but what's a typical price for such an attack if our competitors paid for it through some kind of botnet service? It is really starting to scare me (if we're talking thousands of dollars here, then I am really going to freak off: who knows, they might just hire a hit-man one day?). Of course we filed a complaint, but the police says that they cannot do much about it (DDoS attacks are virtually untraceable, so they say), and our suspicions are not enough to justify them raiding our competitor's offices to search for proofs. For your information, we now changed our infrastructure to be able to sustain such attacks: we now use a major CDN service so that our servers are not directly affected by DDoS attacks. Requests for dynamic pages do get proxied to our servers, but for low level attacks (UDP flood, or Syn floods, for example) we only receive legitimate trafic, so we're fine. If they decide to launch higher level attacks (HTTP flood or slowloris attacks for example), most of the load should be handled by the CDN... at least I hope so! Thank you very much for your help.

  • Mixed sessions with Classic ASP on IIS 7.5 and Windows 2008 R2 64 bit

    - by Marcin
    Recently had an issues with a server upgrade from IIS 6 on Windows 2003 to IIS 7.5 on Windows 2008 R2 64 bit. We have a number of websites running on Classic ASP. All the sites sit under a particular site, e.g. www.example.com/foo and www.example.com/foobar. On IIS 6 each site was set up as a virtual directory and things worked fine. Since moving to the new set up, a lot of websites seem to have mixed Sessions. To be clear, this is not a app pool recycling issue; rather the sessions are populated with information when the user hits the site and while browsing they get sessions from different sites. We've determined this based on - a few customers called up and reported having their shopping cart with items with names of items belonging to a different site - also our own testing showed that some queries being run would try to bring products in from a different site We've tried - disabling dynamic caching - converting each site to be a virtual application (if I understand correctly, the virtual directory/application concepts were changed/refined somewhat in IIS 7 although to be honest, I'm not clear what the difference is) - various application pool changes (using .NET 2 framework), classic and integrated modes, changing the Process model to NetworkIdentity), all to no avail. The only thing we haven't tried is changing it to run as a 32 bit application. We're not using http only cookies, so when I open up a browser and type document.cookie into the dev console in Firefox/Chrome/IE that there will be multiple ASPSESSIONID=... values whereas previously I believe there was only one. Finally, we use server side JScript for the classic ASP pages, not VBScript, so we have code similar to the below. //the user's login account as a jscript object Session("user") = { email : "[email protected]", id : 123 }; and if we execute a line of code like below: Response.Write( typeof(Session("user")) ); When things are running correctly, we get "object" - as expected. When the Session gets trashed, the output is "unknown" and we are also unable to access the fields within the JScript object (e.g. the .email or .id fields). Much appreciated if anyone can provide any pointers about how to resolve this, everything on google seems to point to different issues.
