• Selenium server causes crazy load on server - how to prevent?

  - by Eric

  I'm running this linux: Linux host.themepark.com 2.6.32-220.4.1.el6.x86_64 #1 SMP Tue Jan 24 02:13:44 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux And I run the Selenium stand-alone server on my box with this command: java -jar /home/l/cron/selenium-server-standalone-2.24.1.jar > /logs/selenium.log 2>&1 & Here's the problem: as soon as I do that, the server load starts skyrocketing. I even went back and downloaded older versions of the Selenium server, but same results with 2.23.1, 2.23.0, and 2.19.0. Note that the server load starts going nuts before I issue ANY commands to Selenium or do anything else. All I'm doing is firing up the server, per the command above. This used to work perfectly on my server without causing massive server load, so something has changed, but I'm not sure what. My server is a managed VPS so I don't know if there is some kind of auto-update script that kicked in or what... but it's a problem. (Incidentally, even though the server load climbs like crazy, everything still works: after firing up Selenium, my server creates a screen with Xvfb so Firefox will be happy, then a PHP script talks to Selenium to do what it needs to do before shutting everything down. It takes a LONG time, and the load gets all the way up to 8 [!!!] before it is finished, which kills my web server and makes the main site horribly unresponsive... but it does get everything done.) Any suggestions for what is going on, why it's started doing this and/or, most importantly, how I can make Selenium not kill the server when it starts up... would be GREATLY appreciated!

• Drop database on DB2 9.5 - SQL1035N The database is currently in use

  - by Tommy

  I've never got this working the first time, but now I can't seem to do i at all. There is a connection pool somewhere using the database, so trying to drop the database when an application is using the database should give this error. The problem is there are no connection to the database when I issue these commands: db2 connect to mydatabase db2 quiesce database immediate force connections db2 connect reset db2 drop database mydatabase This allways give: SQL1035N The database is currently in use. SQLSTATE=57019 running this command shows no connections/applications DB2 list applications I can even deactivate the database, but still can't drop it. db2 => deactivate database mydatabase DB20000I The DEACTIVATE DATABASE command completed successfully. db2 => drop database mydatabase SQL1035N The database is currently in use. SQLSTATE=57019 db2 => Anyone got any clues? I'm running the cmd-windows as the local administrator (windows 2008) and this is also the admin for DB2. The connectionpool-user cannot connect during quiesce-state.

• How to list rpm packages/subpackages sorted by total size

  - by smci

  Looking for an easy way to postprocess rpm -q output so it reports the total size of all subpackages matching a regexp, e.g. see the aspell* example below. (Short of scripting it with Python/PERL/awk, which is the next step) (Motivation: I'm trying to remove a few Gb of unnecessary packages from a CentOS install, so I'm trying to track down things that are a) large b) unnecessary and c) not dependencies of anything useful like gnome. Ultimately I want to pipe the ouput through sort -n to what the space hogs are, before doing rpm -e) My reporting command looks like [1]: cat unwanted | xargs rpm -q --qf '%9.{size} %{name}\n' > unwanted.size and here's just one example where I'd like to see rpm's total for all aspell* subpackages: root# rpm -q --qf '%9.{size} %{name}\n' `rpm -qa | grep aspell` 1040974 aspell 16417158 aspell-es 4862676 aspell-sv 4334067 aspell-en 23329116 aspell-fr 13075210 aspell-de 39342410 aspell-it 8655094 aspell-ca 62267635 aspell-cs 16714477 aspell-da 17579484 aspell-el 10625591 aspell-no 60719347 aspell-pl 12907088 aspell-pt 8007946 aspell-nl 9425163 aspell-cy Three extra nice-to-have things: list the dependencies/depending packages of each group (so I can figure out the uninstall order) Also, if you could group them by package group, that would be totally neat. Human-readable size units like 'M'/'G' (like ls -h does). Can be done with regexp and rounding on the size field. Footnote: I'm surprised up2date and yum don't add this sort of intelligence. Ideally you would want to see a tree of group-package-subpackage, with rolled-up sizes. Footnote 2: I see yum erase aspell* does actually produce this summary - but not in a query command. [1] where unwanted.txt is a textfile of unnecessary packages obtained by diffing the output of: yum list installed | sed -e 's/\..*//g' > installed.txt diff --suppress-common-lines centos4_minimal.txt installed.txt | grep '>' and centos4_minimal.txt came from the Google doc given by that helpful blogger.

• Outside VPN traffic not able to ping site-to-site VPN remote site

  - by Siriss

  we have two ASA 5510s running 8.4 in a site-to-site VPN setup. All internal traffic is working smoothly. Site/Subnet A: 192.100.0.0 - local Site/Subnet B: 192.200.0.0 - remote VPN Users: 192.100.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible. Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise. I know I am missing a NAT rule, and in 8.2, it was easy as pie to setup using ASDM, but now I can't get it for the life of me as 8.4 apparently made a lot of changes to NAT rules. I am not too comfortable in the ASA command line, but if there is a command I need to add or if you could direct me where I can add this in 8.4 ASDM I would really appreciate it. I have tired NAT Exempt, Static NAT, Static NAT Policies, etc... I think I tried all the options. I also might have my interfaces confused with the new look at feel of ASDM. Thank you much in advance and I hope I have been thorough enough.

• How to transition to Comcast with static IP address [migrated]

  - by steveha

  I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

• upstart config to start sync daemon as non-root user

  - by Rudiger Wolf

  I am planning to use inosync to sync data from master server to several client servers. I have created a user called rsyncuser in both master and slaves with access permissions and passwordless ssh access from master to slave servers. Inosync is working when I use it from the command line as rsyncuser. Next I want this to start automatically when server is turned on. I figured upstart is the way to get this working. I am unable to find the right upstart command to get this working. Here is my upstart conf file. The problem seems to be around running "inosync -d -c /etc/inosync/inosync_rsyncuser.py" as a given user. As you can see I have tried a number of various options! description "start inosync to sync data to other CDN Servers as rsyncuser" console output #start on startup #stop on shutdown start on (net-device-up and local-filesystems) stop on runlevel [016] #start on runlevel [2345] #stop on runlevel [!2345] #kill timeout 30 env RUN_AS_USER=rsyncuser expect fork script echo "Inosync updtart job seems to have started" /tmp/upstart.log # exec sudo -u rsyncuser -c "ls -la" /tmp/upstart.log 2&1 # LOGFILE=/var/log/logfile.`date +%Y-%m-%d`.log # exec su - $RUN_AS_USER -c "inosync -d -c /etc/inosync/inosync_rsyncuser.py" $LOGFILE 2&1 # exec su -c "ls -la" /tmp/upstart.log 2&1 # emit inosync_running end script

• Can't successfully run Sharepoint Foundation 2010 first time configuration

  - by Robert Koritnik

  I'm trying to run the non-GUI version of configuration wizard using power shell because I would like to set config and admin database names. GUI wizard doesn't give you all possible options for configuration (but even though it doesn't do it either). I run this command: New-SPConfigurationDatabase -DatabaseName "Sharepoint2010Config" -DatabaseServer "developer.mydomain.pri" -AdministrationContentDatabaseName "Sharepoint2010Admin" -DatabaseCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "%h4r3p0int" -AsPlainText -Force) Of course all these are in the same line. I've broken them down into separate lines to make it easier to read. When I run this command I get this error: New-SPConfigurationDatabase : Cannot connect to database master at SQL server a t developer.mydomain.pri. The database might not exist, or the current user does not have permission to connect to it.

• Problem running mysql client, cannot connect to mysql server

  - by ehsanul

  Edit3: Thanks for the help everyone. Sorry for wasting anybody's time, but it seems like a simple reboot solved it. I should've known better, but I just had the assumption that the "restart" solution is mostly valid just for MS Windows (no offense). I'll keep this in mind before I ask a question here again. I installed the mysql-client-5.0 and mysql-server-5.0 packages on Ubuntu 8.04, using sudo apt-get install. When I try to run the "mysql" command, I get the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) To verify that mysql server is running, I tried this, and it does seem to be running, with the correct socket too: $ ps aux | grep mysql root 13388 0.0 0.0 1772 528 ?

Note that I'm completely new to mysql. Edit: As requested in comments, the exact command that is returning the error is simply "sudo mysql". And when I check netstats for active networks services, I do see an entry for port 3306, with Protocol: tcp, IP Source: 127.0.0.1, State: LISTEN Edit2: It appears as if the /var/run/mysqld/mysqld.sock socket doesn't exist (if I'm interpreting the following output correctly): $ ls -al /var/run/mysqld/ total 0 drwxr-xr-x 2 mysql root 40 2009-08-06 06:36 . drwxr-xr-x 20 root root 860 2009-08-06 06:25 ..

• Solaris: detect hotswap SATA disk insert

  - by growse

  What's the method used on Solaris to get the system to rescan for new disks that have been hot-plugged on a SATA controller? I've got an HP X1600 NAS which had 9 drives configred in a ZFS pool. I've added 3 disks, but the format command still only shows the original 9. When I plugged them in, I saw this: cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=12 cpqary3: [ID 479030 kern.notice] Configured Drive ? ....... NO cpqary3: [ID 100000 kern.notice] cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=11 cpqary3: [ID 479030 kern.notice] Configured Drive ? .......

NO But can't figure out how to get the format command to see them so I know they've been detected by the system.

• Fedora distribution update pop-up after fresh installation

  - by Sayan Ghosh

  Hi, We do a kickstart installation of FC-10 at our place. I am quite intimidated by the distribution update pop up that comes up after the O/S installation. I want a keyword to put into the kickstart file that would stop Fedora from intimating with an update pop-up. Is it possible to include such a switch in the kickstart OR a script that could be added to post.bash? Thanks, Sayan

• How often is CRL refreshed, and how to force it to be?

  - by lockstock

  I have a web service running under IIS 7 that requires an X509 client certificate. I know that the server that it rus on needs access to DigiCert.com in order to be able to get the CRL (Certificate Revocation List). There is a need to change our proxy so I am attempting to investigate the impact of doing so. I have removed the global proxy settings using the command netsh winhttp proxy refesh, and also deleted the CRL cache using the command certutil -URLcache CRL delete. However, after doing this, all calls to the web service still succeed. This suggests to me that I am missing something here. So; If the CRL cache is cleared and the server has no way of refreshing the CRL, why do web service requets not return http 403?. I have been unable to find adequate information from googling nor from my colleagues. The reason I want it to fail is that I will not be confident that the new proxy settings work until I can see it broken first, if that makes sense. I would also like to be able to force the CRL to be refeshed in order to ensure that the new proxy settings work

• How to push configurations to multiple Cisco Switches

  - by nixda

  Assume I have around 50 Cisco IE2000 Switches connected together and I want to reconfigure some settings, the same settings for every switch. Normally I would open a command line session via Putty and paste the commands. But as the number of switches is growing, even this method takes its time. I am aware of Kiwi CatTools. Unfortunately it's not free so I'm wondering if there are other efficient ways to configure a large number of Cisco switches.

• If spaces in filenames are possible, why do some of us still avoid using them?

  - by Chris W. Rea

  Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. NamingThingsLikeThis.txt -- despite most modern operating systems supporting spaces in filenames. Non-technical people must look at filenames created by geeks and wonder where we learned English. So, what are the reasons that spaces in filenames are avoided or discouraged? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant reasons, other than the practice being a vestigial preference? UPDATE: Thanks for all your answers! I'm surprised how popular this was. So, here's a summary: Six Reasons Why Geeks Prefer Filenames Without Spaces In Them It's irritating to put quotes around them when referenced on the command line (or elsewhere.) Some older operating systems didn't used to support them and us old dogs are used to that. Some tools still don't support spaces in filenames at all or very well. (But they should.) It's irritating to escape spaces when used where spaces must be escaped, such as URLs. Certain unenlightened services (e.g. file hosting, webmail) remove or replace spaces anyway! Names without spaces can be shorter, which is sometimes desirable as paths are limited.

• Configuring vsftpd with nginx on Ubuntu 12.04 LTS

  - by arby

  I've attempted to configure a nginx / vsftpd server on Ubuntu 12.04 LTS (via amazon ec2) a couple times now, but I seem to keep making a mistake along the way. Currently, when I try to connect to my ftp server it takes a minute or so before it connects. Then when I issue a command, they all timeout with an operation failed error. Aside from these issues, I'm not completely confident with the file ownership & permissions or the configuration / settings. So, I think it's best if I just re-install and re-configure correctly. I believe the nginx installation comes with a default user of www-data:www-data and web root directory ownership by root:root. Vsftpd, however, needs to have a user created with the same group as the nginx user (www-data), and the same home directory as the nginx server (/usr/share/nginx/www), with g+w chmod permissions granted on that directory. The vsftpd.conf file should disable anonymous logins and enable local logins, file writing, and chroot local users. In my previous config, I had /bin/false set for the ftp user's shell and pam_shells.so disabled. I also had local_umask set to 0027. So, starting with a fresh ec2 instance, I've got: sudo apt-get install vsftpd sudo apt-get install nginx For the firewall I issued the command (not sure if necessary): sudo ufw allow ftp Which commands / config is recommended from here? I only need 1 ftp user that I can use to login with my ftp client to modify the single nginx web domain, which will need php & sql for WordPress.

• VMware Workstation executes nonexisting and outdated File

  - by RED SOFT ADAIR-StefanWoe

  I execute a command line program from a VM (VMware 7.1.1) with Windows XP. The executable file is located on the host machine. If i start a command line in the VM, using a drive mounted as .host\SharedFolders i see the following: D:\projects\myProgram\WinRel>dir myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe D:\projects\myProgram\WinRel>myProgram.exe Processing BuildFeb 26 2009 This is wrong! The whole execution of the program behaves like the version that is outdated more than one year! I triple checked that there is no confusion or anything If i start the Program on the host or if i even start it from the VM using a UNC Path, it shows the last build date and executes as expected: C:\>dir \\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe C:\>\\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe Processing Build: Sep 2 2010 Can this behavior somehow be explained? There MUST be a cache for the host mounted drive. The program it executes does not exist anymore! If i remove it from the host, the VM can not execute it anymore. If i restore it, the behavior becomes the same again.

• configuring vsftpd anonymous upload. Creates files but freezes at 0 bytes

• 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.

• How do I use postfix aliases in cyrus?

  - by Nick

  I have a cyrus mailbox called user/nrahl. If I use the 'mail' command, from the server itself, and type: mail nrahl to send a message, the message magically shows up in my Thunderbird IMAP inbox. But I need to get message from a POP3 account into Cyrus for delivery, and the messages comming in are addressed to "[email protected]". I have fetchmail setup and running, and it's downloading messages from the POP3 account, and passing them into Postfix. Postfix (now that I've got aliases set up in /etc/alias) is accepting the message, and passing it to the Cyrus socket. But here's the problem: Cyrus is rejecting the message with a 550 - mailbox unknown error. The actual message in /var/log/mail.log is: Apr 17 16:56:57 IMAP cyrus/lmtpunix[5640]: verify_user(user.fetchmail) failed: Mailbox does not exist Apr 17 16:56:57 IMAP postfix/lmtp[5561]: CFFD61556BD: to=, relay=localhost[/var/run/cyrus/socket/lmtp], delay=0.08, delays=0.07/0/0/0.01, dsn=5.1.1, status=bounced (host localhost[/var/run/cyrus/socket/lmtp] said: 550-Mailbox unknown. Either there is no mailbox associated with this 550-name or you do not have authorization to see it. 550 5.1.1 User unknown (in reply to RCPT TO command)) It looks like it's trying to forward all of nrahl's mail to postfix@localhost, instead of nrahl@localhost, and I don't know why. I need it to forward mail addressed to [email protected] into Cyrus's "nrahl" mailbox.
