• Internet Explorer / Windows 7 does not want to show HTML file from local network drive

  - by Jaanus

  Setup: I have Windows 7 running inside VirtualBox on Mac OS X host. I have a shared drive with some HTML files, that I am mounting as a local drive W: in Windows, from the VirtualBox server \VBOXSVR. I want to look at them with a browser in Windows. Chrome in Windows 7 opens and shows those HTML files just fine (file:///W:/welcome.html). But Internet Explorer does not, and shows this error instead of the files: Internet Explorer cannot display the web page What you can try: [button Diagnose Connection Problems] More information This problem can be caused by a variety of issues, including: Internet connectivity has been lost. The website is temporarily unavailable. The Domain Name Server (DNS) is not reachable. The Domain Name Server (DNS) does not have a listing for the website's domain. If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. For the internet zone in the status bar, it shows: Internet | Protected Mode: On IE settings are a mystery to me, and I could possibly get it to work by tweaking IE settings, but I don't know which ones. How do I make IE show the same files that Chrome is happy to show? (Chrome showing them means that the files themselves are fine, there is something about the setup that just makes IE be a diva.)

• Apache MaxClients reaching max and locking the server

  - by Rodrigo Sieiro

  Hi. I currently have an Apache2 server running with mpm-prefork and mod_php on a OpenVZ VPS with 512M real / 1024M burstable RAM (no swap). After running some tests, I found that the maximum process size Apache gets is 23M, so I've set MaxClients to 25 (23M x 25 = 575 MB, ok for me). I decided to run some load tests on my server, and the results left me puzzled. I'm using ab on my desktop machine requesting the main page from a wordpress blog. When I run ab with 24 concurrent connections, everything seems fine. Sure, CPU goes up, free RAM goes down, and the result is about 2-3s response time per request. But if I run ab with 25 concurrent connections (my server limit), Apache just hangs after a couple of seconds. It starts processing the requests, then it stops responding, CPU goes back to 100% idle and ab times out. Apache log says it reached MaxClients. When this happens, Apache keeps itself locked up with 25 running processes (they're all in "W" if I check server status) and only after the TimeOut setting the processes start to die and the server starts responding again (in my case it's set to 45). My question: is that expected behaviour? Why Apache just dies when it reaches MaxClients? If it works with 24 connections, shouldn't it work with 25, just taking maybe more time to respond each request and queueing up the rest? It sounds kinda strange to me that any kid running ab can alone kill a webserver just by setting the concurrent connections to the servers MaxClients.

• How can I get MySQL 5.5 to log warnings to one of the log files?

  - by Wodin

  I have found various things that say that you can log warnings to the MySQL error log, but I have not been able to actually make it happen. I do have the error log working, and MySQL prints stuff to it on startup and shutdown and occasionally at other times, but if I e.g. SELECT CAST('123' AS DATE); and then SHOW WARNINGS; I can see the warning, but it does not show up in any logs. I've also tried enabling the general log and the slow query log, but these don't show the warnings either. I've tried with log_warnings = 1 and log_warnings = 2, but still no warnings are logged. What am I doing wrong? mysql> show variables like '%error%'; +--------------------+--------------------------+ | Variable_name | Value | +--------------------+--------------------------+ | error_count | 0 | | log_error | /var/log/mysql/mysql.err | | max_connect_errors | 10 | | max_error_count | 1024 | | slave_skip_errors | OFF | +--------------------+--------------------------+ mysql> show variables like '%warn%'; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | log_warnings | 1 | | sql_warnings | OFF | | warning_count | 0 | +---------------+-------+ 3 rows in set (0.06 sec) mysql> show variables like '%log%'; +-----------------------------------------+-------------------------------+ | Variable_name | Value | +-----------------------------------------+-------------------------------+ ... | general_log | ON | | general_log_file | /var/log/mysql/general.log | ... | log | ON | ... | log_error | /var/log/mysql/mysql.err | | log_output | FILE | | log_queries_not_using_indexes | ON | ... | log_warnings | 1 | ... | slow_query_log | ON | | slow_query_log_file | /var/log/mysql/mysql-slow.log | ... +-----------------------------------------+-------------------------------+ Edit: mysql> show global status like 'Aborted%'; +------------------+-------+ | Variable_name | Value | +------------------+-------+ | Aborted_clients | 24 | | Aborted_connects | 15 | +------------------+-------+ 2 rows in set (0.08 sec) Edit: Clarification: I do get [Warning] Aborted connection 1 to db... and [Warning] Access denied for user... messages logged, but not the warnings that you can see via SHOW WARNINGS after e.g. inserting something or running LOAD DATA INFILE... which is what I'm looking for.

• Disabling CPU management

  If I add the following processor.max_cstate=0 to the kernel command line for boot up, does that disable all CPU power management and throttling?

• Grant access for users on a separate domain to SharePoint

  - by Geo Ego

  Hello. I just completed development of a SharePoint site on a virtual server and am currently in the process of granting users from a different domain to the site. The SharePoint domain is SHAREPOINT, and the domain with the users I want to give access to is COMPANY. I have provided them with a link to the site and added them as users via SharePoint, which is all I thought I would need to do. However, when they go to the link, the site shows them a SharePoint error page. In the security event log, I am showing the following: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:11:49 AM User: COMPANY\ThisUser Computer: SHAREPOINT Description: Object Open: Object Server: Security Account Manager Object Type: SAM_ALIAS Object Name: DOMAINS\Account\Aliases\00000404 Handle ID: - Operation ID: {0,1719489} Process ID: 416 Image File Name: C:\WINDOWS\system32\lsass.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: ThisUser Client Domain: PRINTRON Client Logon ID: (0x0,0x1A3BC2) Accesses: AddMember RemoveMember ListMembers ReadInformation Privileges: - Restricted Sid Count: 0 Access Mask: 0xF Then, four of these in a row: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:12:08 AM User: NT AUTHORITY\NETWORK SERVICE Computer: SHAREPOINT Description: Object Open: Object Server: SC Manager Object Type: SERVICE OBJECT Object Name: WinHttpAutoProxySvc Handle ID: - Operation ID: {0,1727132} Process ID: 404 Image File Name: C:\WINDOWS\system32\services.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: NETWORK SERVICE Client Domain: NT AUTHORITY Client Logon ID: (0x0,0x3E4) Accesses: Query status of service Start the service Query information from service Privileges: - Restricted Sid Count: 0 Access Mask: 0x94 Any ideas what permissions I need to grant to the user to get them access to SharePoint?

• smartctl not actually running self tests?

  - by canzar

  I want to run the smartctl self tests to check the health of the drives in my RAID array (PERC 5/i). The array is on sda and comprises six drives. I can check the status using sudo smartctl /dev/sda -d megaraid,0 -a And I see that SMART is available and enabled on all the drives. I have tried to run self tests using sudo smartctl /dev/sda -d megaraid,0 -t short and sudo smartctl /dev/sda -d megaraid,0 -t long I have also tried it on all of the drives 0-5. No matter what I try, when I run: sudo smartctl /dev/sda -d megaraid,0 -l selftest I always get the same result, which seems to always report that I have never run a self test. /dev/sda [megaraid_disk_00] [SAT]: Device open changed type from 'megaraid' to 'sat' ===START OF READ SMART DATA SECTION === SMART Self-test log structure revision number 1 No self-tests have been logged. [To run self-tests, use: smartctl -t] From what I read, I should have no problem running the short and long self tests on the array while it is mounted. Does anyone else have experience running these tests on a PERC 5/i raid array who could lend some insight into what is causing the problem?

• Smart Array P400 battery failure

  - by RobIII

  The P400 Smart Array controller in my HP DL380G5 is indicating: Battery Status: Failed, Replace Battery 1 in the System Management Homepage. Also the IML indicates: POST Error: 1794-Drive Array - Array Accelerator Battery Charge Low I do have several replacement batteries (actually, several controllers including batteries) lying around at work but never had to actually replace one. I am wondering if the battery replacement (swap) could be done hot or if I need to take down my server to do the battery replacement. I have replaced other spare parts like fans and drives before and all those can be replaced hot. I just don't know about the battery of the P400 Smart Array controller. Any help would be appreciated. EDIT1 For those interested: straight from the horse's mouth: With thanks to Frands Hansen pointing it out here. EDIT2 In the end I did just power down, to be on the safe side and because the manual says so, and replace the battery. Couldn't be easier. Unplugged the old one of the end of the cable (not the end connected to the controller) and reconnected a spare one. The replaced battery is now in the server for about an hour and currently (still) recharging. I'm assuming all will end wel.

• IPv4 not enabled in Windows 7

  - by RidDeBakTiYar

  I have a Netbook with Win 7 Starter edition. I am not able to get IPv4 enabled/installed in the Netbook and hence not able to network/connect to Internet. It says "Limited access" when I check connections. It all began when my system crashed and I was not able to get thro beyond the boot screen. The system advice me to try repair with the original OS cd and I did the same. After that the Netbook has booted, but is not able to network. On a detailed study I found that the Network adapter has both IPv4 and IPv6 Protocols, but there are some differences. The IPv4 is not having the "Properties" enabled to configure, while the IPv6 is having "Properties" enabled. I have only a IPv4 Wired and Wireless at home and its not able to get the Netbook connected as it cannot I had tried uninstalling the Adapter to allow windows to automatically detect and install. Using the "netsh" command to uninstall and install, but not having any change in status. There is a option to "Have disk" under add Protocol, but I don't know how to give the standard IPv4 for installation (asking for *.inf). Any help in solving the issue will be very much appreciated

• ZFS - Impact of L2ARC cache device failure (Nexenta)

  - by ewwhite

  I have an HP ProLiant DL380 G7 server running as a NexentaStor storage unit. The server has 36GB RAM, 2 LSI 9211-8i SAS controllers (no SAS expanders), 2 SAS system drives, 12 SAS data drives, a hot-spare disk, an Intel X25-M L2ARC cache and a DDRdrive PCI ZIL accelerator. This system serves NFS to multiple VMWare hosts. I also have about 90-100GB of deduplicated data on the array. I've had two incidents where performance tanked suddenly, leaving the VM guests and Nexenta SSH/Web consoles inaccessible and requiring a full reboot of the array to restore functionality. In both cases, it was the Intel X-25M L2ARC SSD that failed or was "offlined". NexentaStor failed to alert me on the cache failure, however the general ZFS FMA alert was visible on the (unresponsive) console screen. The zpool status output showed: pool: vol1 state: ONLINE scan: scrub repaired 0 in 0h57m with 0 errors on Sat May 21 05:57:27 2011 config: NAME STATE READ WRITE CKSUM vol1 ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c8t5000C50031B94409d0 ONLINE 0 0 0 c9t5000C50031BBFE25d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c10t5000C50031D158FDd0 ONLINE 0 0 0 c11t5000C5002C823045d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c12t5000C50031D91AD1d0 ONLINE 0 0 0 c2t5000C50031D911B9d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c13t5000C50031BC293Dd0 ONLINE 0 0 0 c14t5000C50031BD208Dd0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c15t5000C50031BBF6F5d0 ONLINE 0 0 0 c16t5000C50031D8CFADd0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c17t5000C50031BC0E01d0 ONLINE 0 0 0 c18t5000C5002C7CCE41d0 ONLINE 0 0 0 logs c19t0d0 ONLINE 0 0 0 cache c6t5001517959467B45d0 FAULTED 2 542 0 too many errors spares c7t5000C50031CB43D9d0 AVAIL errors: No known data errors This did not trigger any alerts from within Nexenta. I was under the impression that an L2ARC failure would not impact the system. But in this case, it surely was the culprit. I've never seen any recommendations to RAID L2ARC. Removing the bad SSD entirely from the server got me back running, but I'm concerned about the impact of the device failure (and maybe the lack of notification from NexentaStor as well). Edit - What's the current best-choice SSD for L2ARC cache applications these days?

• Cannot connect to server via SSH

  - by Rayne

  I'm running RHEL 6.0, and I accidentally moved the /bin, /boot, /cgroup, console.txt, /data, /dev, /etc to another folder. I think I managed to move these folders back, but now I'm having trouble connecting to the server using SSH, but am able to access the server via VNC. When I tried to connect to the server using a terminal from another server, I get the error ssh_exchange_identification: Connection closed by remote host I'm currently still connected via SSH to the server (haven't closed the window yet), and am still able to access it normally. But if I try to open a new SSH terminal from my current session, I see /bin/bash: Permission denied If I try to open a new SSH File Transfer window from my current session, I get the error File transfer server could not be started or it exited unexpectedly. Exit value 0 was returned. Most likely the sftp-server is not in the path of the user on the server-side I checked and I have Subsystem sftp /usr/libexec/openssh/sftp-server which is the same path as the output of locate sftp-server Also, when I tried to restart sshd, I get the error Couldn't open /dev/null: Permission denied But my /dev/null has the permissions crw-rw-rw- for root,root. How can I resolve this? ETA: Thanks for all your help! I was able to start ssh by running the application directly /usr/sbin/sshd Even though the status of the openssh-daemon is still "stopped".

• sql developer cannot establish connection to oracle db with listener running

  - by lostinthebits

  I am working from home and connected to my work's vpn. I have tried to connect to the work db with sql developer (the latest version and the previous version) on the following environments: mac os x 10.8.5 (with sql developer launched and installed directly on the iMac. sql developer launched and installed directly on a vm on same computer (guest Ubuntu 12.04 LTS) sql developer launched and installed directly on a vm on same computer (guest Windows 7.0 Professional) I get Status Failure Test Failed : IO Error - The Network Adapter could not establish the connection. I have read dba forums and googled and the most common suggestion is that the oracle listener is not up and running. I can conclusively say this is not the case because I have the option of using remote desktop and accessing the oracle db in question on my work computer. If the listener was down, according to my DBA, no one would be able to connect. My sysadmin and dba are stumped so I assume it is something unique to my home system. The reason I do not want to continue with the remote desktop workaround is because remote desktop has an annoying (infuriating often) lag.

• Whitelist IP from google-authenticator in sshd pam

  - by spudwaffle

  My Ubuntu 12.04 server uses the google-authenticator pam module to provide two step authentication for ssh. I need to make it so that a certain IP does not need to type the verification code. The /etc/pam.d/sshd file is below: # PAM configuration for the Secure Shell service # Read environment variables from /etc/environment and # /etc/security/pam_env.conf. auth required pam_env.so # [1] # In Debian 4.0 (etch), locale-related environment variables were moved to # /etc/default/locale, so read that as well. auth required pam_env.so envfile=/etc/default/locale # Standard Un*x authentication. @include common-auth # Disallow non-root logins when /etc/nologin exists. account required pam_nologin.so # Uncomment and edit /etc/security/access.conf if you need to set complex # access limits that are hard to express in sshd_config. # account required pam_access.so # Standard Un*x authorization. @include common-account # Standard Un*x session setup and teardown. @include common-session # Print the message of the day upon successful login. session optional pam_motd.so # [1] # Print the status of the user's mailbox upon successful login. session optional pam_mail.so standard noenv # [1] # Set up user limits from /etc/security/limits.conf. session required pam_limits.so # Set up SELinux capabilities (need modified pam) # session required pam_selinux.so multiple # Standard Un*x password updating. @include common-password auth required pam_google_authenticator.so I've already tried adding a auth sufficient pam_exec.so /etc/pam.d/ip.sh line above the google-authenticator line, but I can't understand how to check an IP adress in the bash script.

• How to I make my bootcamp partition bootable again?

  - by KJFMusic

  I'm having a similar problem as everyone else in this posting. I have 5 partitions. 3 of which I created for my Mac OS Lion installation, Windows 7 installation and a 3rd for storage. Everything was running fine for quite sometime until recently. My Windows 7 installation has suddenly stopped booting. Instead of a start up screen I get: Windows failed to start. A recent hardware or software change might be the cause. File: \BOOT\BCD Status: 0xc000000d Info: An error occurred while attempting to read the boot configuration data Mac OS Lion starts up fine. I'm unable to mount my "Bootcamp" partition nor the "Storage" partition. On top of that "Storage" has been renamed to "disk0s5". When I installed Windows 7 it didn't recognize the "Storage" partition that was created in Lion so it merged what it thought was free diskspace (I'm assuming the same space that Mac OS recognized as Storage) to the Root Drive of Windows 7 (Bootcamp). Are you able to assist?

• openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

  - by JoJoeDad

  I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

• Recommended programming language for linux server management and web ui integration

  - by Brendan Martens

  I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects that already integrate management of many systems into a single cohesive web ui, except Landscape (not free,) Ebox (ebox control center not free) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo. Also, only manages one system.) Thanks for any ideas! Update: I am not looking to reinvent the wheel of systems management, I just want to "glue" many preexisting and excellent tools together where possible and appropriate; this is why I wonder about what languages can interact well with pre-existing command line tools, while making them manageable with a web ui.

• SSH dynamic port forwarding, "Connection refused"

  - by crodjer

  I am trying to do dynamic portforwarding using openssh through a remote computer following this command: ssh -D 6789 rohan@<remote_ip> -p <remote_port> This should set up a socks server on my comp as I assume. I am able to use this for normal browsing but can't connect to IRC or remote ssh (through proxychains).

• Browsing Playstation 3 from Ubuntu Box

  - by zfranciscus

  Hi, My Goal here is to be able to transfer files from my Ubuntu 10.04 box to my PS3 over a wireless network. My PS3 and my Ubuntu Box is on the same home network. These are some stuff that I tried: I can't see my PS 3 from 'Places ? Network' nor other computer that is running on windows. I am still puzzled by this fact. I have not tried ping-ing my PS3. I'll try that later today and post the result in the forum I install PS3MediaServer (http://code.google.com/p/ps3mediaserver/). Someone in the PS3 chat forum (http://www.ps3chat.com/playstation-3...lp-please.html) claims that it will enable your ubuntu box to browse PS3. So I downloaded PS3MediaServer, and ran the software. The status tab keep showing "Waiting ...". It seems that PS3MediaServer can't find my PS3. Some how I feel that 1 and 2 are related somehow.Perhaps that there is something wrong with my Ubuntu network settings that is preventing my ubuntu box from looking up other device on the network. I can go to the Internet fine, but I can't see other device on my network. Does anyone have any experience in this area. I would like to hear your experience and perhaps some solution. Any kind of hints or help will be greatly appreciated. Cheers

• org-sort multi: date/time (?d ?t) | priority (?p) | title (?a)

  - by lawlist

  Is anyone aware of an org-sort function / modification that can refile / organize a group of TODO so that it sorts them by three (3) criteria: first sort by due date, second sort by priority, and third sort by by title of the task? EDIT: I believe that org-sort by deadline (?d) has a bug that cannot properly handle undated tasks. I am working on a workaround (i.e., moving the undated todo to a different heading before the deadline (?d) sort occurs), but perhaps the best thing to do would be to try and fix the original sorting function. Development of the workaround can be found in this thread (i.e., moving the undated tasks to a different heading in one fell swoop): How to automate org-refile for multiple todo EDIT: Apparently, the following code (ancient history) that I found on the internet was eventually modified and included as a part of org-sort-entries. Unfortunately, undated todo are not properly sorted when sorting by deadline -- i.e., they are mixed in with the dated todo. ;; multiple sort (defun org-sort-multi (&rest sort-types) "Multiple sorts on a certain level of an outline tree, or plain list items. SORT-TYPES is a list where each entry is either a character or a cons pair (BOOL . CHAR), where BOOL is whether or not to sort case-sensitively, and CHAR is one of the characters defined in `org-sort-entries-or-items'. Entries are applied in back to front order. Example: To sort first by TODO status, then by priority, then by date, then alphabetically (case-sensitive) use the following call: (org-sort-multi '(?d ?p ?t (t . ?a)))" (interactive) (dolist (x (nreverse sort-types)) (when (char-valid-p x) (setq x (cons nil x))) (condition-case nil (org-sort-entries (car x) (cdr x)) (error nil)))) ;; sort current level (defun lawlist-sort (&rest sort-types) "Sort the current org level.

Here is an excerpt from the current org.el included within Emacs Trunk (as of July 1, 2013): (defun org-sort (with-case) "Call `org-sort-entries', `org-table-sort-lines' or `org-sort-list'.
