• Offline MySQL installation (Using deb file and no internet connection)

  - by Muhammad Gelbana

  I downloaded MySQL's installation package and ran the following command after installing a fresh Ubuntu server. dpkg -i mysql-5.5.28-debian6.0-x86_64.deb It installed fine and then I tried starting up the server manually /opt/mysql/server-5.5/bin/mysqld And the following error came up /opt/mysql/server-5.5/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory How can I install that library in an offline way ? I have no means whatsoever to an internet connection from that server and I can't even relocate it to have internet connection temporarily ! Thank you.

Thanks. FYI: Dell Latitude D630, Intel Centrino processor. Also, the updater is currently running what seems to be the update. I will report back when it is done going through its process to let you know if it is in fact the 13.10 update. Update 2: System went through an update, but it wasn't for the OS. I think it was an update for the error message mentioned above. Now the OS update is currently running the 'distribution upgrade' portion of the update. This is further than it had gone before. Again I will report back once this is done to let you know whether or not the update was successful. Final Update: Don't know for sure what happened, but I'm almost sure that the error mentioned above was resolved in the first update prior to the 13.10 update. All set.

• MSR Issue on 12.1 Enterprise Controllers

  - by Owen Allen

  We've noticed a problem with MSR initialization and synchronization on Enterprise Controllers that are using Java 7u45. If you're running into the issue, these jobs fail with Java errors. Java 7u45 is bundled with Oracle Solaris 11.1 SRU 12, so if you're using that version or if you plan to use it, you should be aware of this issue. There's a simple fix. You can do the fix before upgrading to SRU 12, but you can't do it before you install the Enterprise Controller. First, log on to the Enterprise Controller system and stop the EC using the ecadm command. This command is in the /opt/SUNWxvmoc/bin directory on Oracle Solaris systems and in the /opt/sun/xvmoc/bin directory on Linux systems: ecadm stop -w Then run this command to fix the issue: cacaoadm set-param java-flags=`cacaoadm get-param -v java-flags -i oem-ec | sed 's/Xss256k/Xss384k/'` -i oem-ec And then restart the EC: ecadm start -w Once you apply this fix, you should be set.

• Server being used to send spam mail. How do I investigate?

  - by split_account

  Problem I think my server is being used to send spam with sendmail, I'm getting a lot of mail being queued up that I don't recognize and my mail.log and syslog are getting huge. I've shutdown sendmail, so none of it is getting out but I can't work out where it's coming from. Investigation so far: I've tried the solution in the blog post below and also shown in this thread. It's meant to add a header from wherever the mail is being added and log all all mail to file, so I changed the following lines in my php.ini file: mail.add_x_header = On mail.log = /var/log/phpmail.log But nothing is appearing in the phpmail.log. I used the command here to investigate cron jobs for all users, but nothing is out of place. The only cron being run is the cron for the website. And then I brought up all php files which had been modified in the last 30 days but none of them look suspicious. What else can I do to find where this is coming from? Mail.log reports Turned sendmail back on for second. Here is a small sample of the reports: Jun 10 14:40:30 ubuntu12 sm-mta[13684]: s5ADeQdp013684: from=<>, size=2431, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:30 ubuntu12 sm-msp-queue[13674]: s5ACK1cC011438: to=www-data, delay=01:20:14, xdelay=00:00:00, mailer=relay, pri=571670, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdp013684 Message accepted for delivery) Jun 10 14:40:30 ubuntu12 sm-mta[13719]: s5ADeQdp013684: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=local, pri=32683, dsn=2.0.0, stat=Sent Jun 10 14:40:30 ubuntu12 sm-mta[13684]: s5ADeQdr013684: from=<[email protected]>, size=677, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:31 ubuntu12 sm-msp-queue[13674]: s5AC0gpi011125: to=www-data, ctladdr=www-data (33/33), delay=01:39:49, xdelay=00:00:01, mailer=relay, pri=660349, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdr013684 Message accepted for delivery) Jun 10 14:40:31 ubuntu12 sm-mta[13721]: s5ADeQdr013684: to=<[email protected]>, ctladdr=<[email protected]> (33/33), delay=00:00:01, xdelay=00:00:00, mailer=local, pri=30946, dsn=2.0.0, stat=Sent Jun 10 14:40:31 ubuntu12 sm-mta[13684]: s5ADeQdt013684: from=<[email protected]>, size=677, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:31 ubuntu12 sm-msp-queue[13674]: s5ACF2Nq011240: to=www-data, ctladdr=www-data (33/33), delay=01:25:29, xdelay=00:00:00, mailer=relay, pri=660349, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdt013684 Message accepted for delivery) Jun 10 14:40:31 ubuntu12 sm-mta[13723]: s5ADeQdt013684: to=<[email protected]>, ctladdr=<[email protected]> (33/33), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30946, dsn=2.0.0, stat=Sent Ju Further Investigation Spotted 4 spam accounts registered in the past day, which is suspicious however all have normal user privileges. There are no contact forms on the site, there are a number of forms and they take either filtered text input or plain text input. Mail is still being queued up having switched the website to maintenance mode, which blocks out everyone but the admin. Ok more investigation, it looks like the email is being send by my websites cron which runs every 5 minutes. However there are no cron jobs I've set-up which run more than once an hour and show on the website log so presumably someone has managed to edit my cron somehow.

• Why doesn't Wolfram Workbench work on 64-bit Ubuntu?

  - by Ian Hincks

  I have downloaded the shell script (Workbench_2.0.0_LINUX.sh), I have run it as root with it giving no complaints, relevant looking files have appeared in /usr/local/Wolfram/WolframWorkbench/2.0/ and it has created the executable "WolframWorkbench" in /usr/local/bin. However, when I run WolframWorkbench from terminal it spits out /usr/local/bin/WolframWorkbench: 46: exec: /usr/local/Wolfram/WolframWorkbench/2.0/WolframWorkbench: not found That file does indeed exist, and is executable. I have also tried running it directly, and I have also tried running the /usr/local/Wolfram/WolframWorkbench/2.0/Executables/WolframWorkbench too. Is there something I'm missing? (I am running Ubuntu 12.04 64bit with openjdk7)

• Remote Display Config.sh Using SSH

  - by john.graves(at)oracle.com

  How often I see people look to VNC, NXMachine, RDP, etc to get a windowing environment on a remote system.  These products are great and I use them too, but there is a fancy feature in SSH to help. ssh –X remoteserver This is a great feature for hooking into headless VirtualBox machines and remote displaying an install wizard. The remote server must have some lines put in the /etc/ssh/sshd_conf file: X11Forwarding yes X11DisplayOffset 10 The second line is optional, but the first is required.  Restart sshd (sudo /etc/init.d/ssh restart). Now I can ssh –X remote server Then run /opt/app/wls10.3.4/wlserver_10.3/common/bin/config.sh to build a new domain. Note: For some reason, the jdk that comes with WebLogic often fails to work on the remote display.  In that case, I modify the config.sh to just use /usr/bin/java (from openjdk-6-jre package).

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• How to open a MIB file in tkmib?

  - by l0b0

  I've tried to open several MIB files in tkmib without success. For example: $ sudo apt-get install tkmib $ wget http://www.mibsearch.com/vendors/Compaq/download/CPQHLTH-MIB $ tkmib CPQHLTH-MIB Click "walk", then you should get an error message like this: setting opts getaddrinfo: CPQHLTH-MIB No address associated with hostname error:snmp_new_session: Couldn't open SNMP session at /usr/lib/perl5/SNMP.pm line 475. unable to create session at /usr/lib/perl5/SNMP.pm line 547.

• Symbolic Link: No such file or directory

  - by Sehe

  i created a symbolic Link from a File at "/opt/bladir/bla" to "bla". So "bla" is now in "/usr/bin/bla". But if i want to call "bla" at terminal, there comes the No such file or directory error. I looked up at "/usr/bin/bla" and the file is linking correctly at "/opt/bladir/bla". What can be the error? P.S. here is my terminal "entry": sudo ln -s /opt/bladir/bla bla Thanks! €: Problem solved. According to the Feature List, 12.04 should have Multiarch support... 'should'. I got the ia32-libs from synaptic and now the program wents just fine. As it looks, my symbolic links where correct. Thank you for all the answers!

• Digikam: What's the problem?

  - by Unapiedra

  I installed Digikam by using the Philip5-PPA. When I run it I get the error below. This is by running it through gdb: Starting program: /usr/bin/digikam /usr/bin/digikam: error while loading shared libraries: libcxcore.so.2.1: cannot open shared object file: No such file or directory [Inferior 1 (process 29894) exited with code 0177] What should I do to find the error and fix it? I can see that somehow libcxcore.so.2.1 is wanted but not found. Is this an error of the PPA, or can I simply point it in the right direction? Can I raise an issue with the PPA creator through launchpad? Some next steps would be quite helpful.

• VPN disconnected: resolv.conf not refreshed

  - by cwall

  I connect to VPN using vpnc. When VPN disconnects, either via time out or the session limit is reached, VPN is terminated, but resolve.conf continues to contain references to my VPN network. resolv.conf before VPN is connected: nameserver 127.0.0.1 search mylocalnetwork resolv.conf after VPN is connected and remains once VPN is lost: nameserver X.X.X.X nameserver X.X.X.Z nameserver 127.0.0.1 search internal.mycompany.com mylocalnetwork In 10.04, when VPN lost, I'd run this script to refresh resolve.conf: 7$ cat bin/refreshResolvconf.sh #!/bin/bash #if [ -e /etc/resolvconf/run/interface/tun0 -a "`pidof vpnc`" == "" ]; then /sbin/resolvconf -d tun0; fi if [ -e /etc/resolvconf/run/interface/tun0 -a "`pidof vpnc`" == "" ] then /sbin/resolvconf -d tun0; echo "Refreshed resolv.conf" fi But, resolveconf changed in 12.04 changed, so this script is no longer applicable. To resolve, I manually edit resolve.conf or turn off/on my connection via "gnome-control-center network". Anyone else have the same problem? How can resolv.conf be updated post-VPN disconnect?

• Insane load average after reboot

  - by Gazzer

  After doing a reboot of Ubuntu server 12.04 LTS (after an apt-get dist-upgrade) my server load (on a 16GB) machine goes insane (around 80) for about 10 or 15 minutes The only things I can think of are these two processes: /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names --batch -e ? select concat('select count(*) into @discard from `',? TABLE_SCHEMA, '`.`', TABLE_NAME, '`') ? from information_schema.TABLES where ENGINE='MyISAM' /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names --silent --batch --force -e select count(*) into @discard from `information_schema`.`PARTITIONS` Is this normal?

• Why is this by passing the SUDO password?

  - by John Isaacks

  I have a bash script I am using to automate a SVN checkout. The contents of the file were: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ Then when I double click the file it would ask me what to do, I would click the button "Run In Terminal" and then a terminal would pop up and ask me for the SUDO password. I would enter it, the script would execute and the terminal would close. I wanted to give some sort of indication that the script ran successfully so I edited my file to look like: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ echo "Head revision has been pushed to live server" I expected the terminal to now stay open and tell me the message afterwards. To my surprise it now opens and immediately closes. The script does execute and I no longer have to put in the SUDO password. Is this right? I do not understand why this is happening, seems like a security issue.

• What You Said: Giving an Old Laptop a New Life

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your tips and tricks for breathing life into an old laptop, now we’re back to share your junk-bin sparing methods. Many of you worked to keep old laptops from getting scrapped by dusting them off and donating them. Mark writes: My acquaintances & friends give me their old computers when they buy a new one. So I disassemble, clean, install an opsys,and get internet working. I also upgrade memory, wireless, etc. from my parts bin. Then I give it to a poor person who needs a computer. Usually a single working mom with kids. I also do the same with old desktops as well. They really appreciate them and It gives me the satisfaction of resurrecting an old computer.

• CentOS - Configuring Puppet to play nice with SELinux

  - by Mike Purcell

  I am running into an issue every time I attempt to start the puppetmasterd service, for which I receive the following error message: root@service1 ~ # -> /etc/init.d/puppetmaster start Starting puppetmaster: Could not prepare for execution: Got 1 failure(s) while initializing: change from absent to directory failed: Could not set 'directory on ensure: Permission denied - /etc/puppet/ssl [FAILED] Apparently there was a known issue with this scenario as outlined in this bug report, however in the bug report it states the issue has been resolved in selinux-policy-3.9.16-29.fc15, but the latest CentOS default upstream version is 3.7.19-155.el6_3.4. So I am trying to figure out the best solution. I can either create a local security policy to allow puppetmasterd the access it needs, or keep researching and install a newer version of selinux-policy outside of the default upstream channel. Anyone have any recommendations? Please don't recommend disabling SELinux... ----- Update ----- Here is the puppet.conf: [main] # The Puppet log directory. # The default value is '$vardir/log'. logdir = /var/log/puppet # Where Puppet PID files are kept. # The default value is '$vardir/run'. rundir = /var/run/puppet # Where SSL certificates are kept. # The default value is '$confdir/ssl'. ssldir = $vardir/ssl [master] certname=puppetmaster.ownij.lan dns_alt_names=puppetmaster.ownij.lan [agent] # The file in which puppetd stores a list of the classes # associated with the retrieved configuratiion. Can be loaded in # the separate ``puppet`` executable using the ``--loadclasses`` # option. # The default value is '$confdir/classes.txt'. classfile = $vardir/classes.txt # Where puppetd caches the local configuration.

• Pronunciation in programming?

  - by Xepoch

  How do you correctly or erroneously pronounce programming terms? Any that you find need strict correction or history into the early CS culture? Programming char = "tchar" not care? ! = bang not exclamation? # = pound not hash? Exception #! = shebang * = splat not star? regex = "rej ex" not "regg ex"? sql = "s q l" not "sequel" (already answered, just i.e.) Unixen | = pipe not vertical bar? bin = bin as in pin , not as in binary? lib = lib as in library , not as in liberate? etc = "ett see" , not "e t c" (as in /etc and not "&c") Annoyance / = slash not backslash LaTeX = "laytek" not "lay teks"

• Offline apt-get update to age of cache

  - by James Haigh

  I have a script to quickly upgrade a Live or fresh system from cached files on a flash drive. In essence, it looks like this: # *Code to remove and symlink /var/cache/apt/ if currently empty of packages.* sudo apt-get dist-upgrade # Quick offline cached upgrade; not limited by slow WANs. echo $'\nMake sure Internet is reachable and press enter for complete online upgrade.'; read sudo apt-get update sudo apt-get dist-upgrade # Complete online upgrade. The problem is that the ‘cached upgrade’ seems to ignore the cached pkgcache.bin and srcpkgcache.bin which is where I assume apt-get update stores its changes, so the upgrade completes as if the system is up-to-date. Useless. So in that case, I need some code to apt-get update to the age of the package cache on my flash drive. This code would be placed between the 1st and 2nd lines of the code above.

• "Backup Intervals" in rsnapshot.conf?

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily
