Intel NIC 82579LM install on ESXi 5.1

Posted on by Andy

Hello,

i had recently the problem that i installed ESXi 5.1 on the local network. Installation and configuration went smoothly but the network card was not recognized. After some reading i found the answer, install a community-compiled driver for that card.

Here a quick how i've got the Intel 82579LM to work:

  1. Download the needed driver here. net-e1000e-2.1.4.x86_64.vib and put it on the disk
  2. Go to your ESXi and make sure that at least your ESXi Shell is enabled then go to the terminal using CTRL+ALT+F1
  3. Login with your root password
  4. Go to the folder you where you stored the driver
  5. Copy the driver to another place
    # cp /path/to/net-e1000 /tmp
  6. Put ESXi into maintenace mode
    # esxcli system maintenanceMode set -e true -t 0
  7. Set the host software level to community
    # esxcli software acceptance set –level=CommunitySupported
  8. Now install the driver
    # esxcli software vib install -v /tmp/net-e1000e-2.1.4.x86_64.vib (path must be absolute)
  9. And exit the maintenance mode
    # esxcli system maintenanceMode set -e false -t 0
  10. That's it, reboot the machine.

Enable TRIM with Non-Apple SSD

Posted on by Andy

DO NOT USE THIS ON OSX 10.10 (YOSEMITE)!!!

Apple enabled TRIM support with OSX Lion (10.7) but there is a catch: apple enabled it only on apple-chosen-SSDs. So if you upgraded your hard drive to a 3rd party manufacturer chances are big that TRIM isn't enabled. Here is how to enable it from commandline:

  1. open terminal
  2. make yourself root
    # sudo su
  3. then change into the needed directory and backup a file
    # cd /System/Library/Extensions/IOAHCIFamily.kext
    # cd Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS
    # cp IOAHCIBlockStorage IOAHCIBlockStorage.backup
  4. than patch the file for Mavericks 10.9.4-10.9.5
    # perl -pi -e 's|(^\x00{1,20})[^\x00]{9}(\x00{1,20}\x54)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' IOAHCIBlockStorage
  5. OR for Mountain Lion 10.8.3 – Mavericks 10.9.3
    # perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00{1,20})[^\x00]{9}(\x00{1,20}\x54)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' IOAHCIBlockStorage
  6. OR for Mountain Lion 10.8.1-10.8.2 and Lion 10.7.5
    # perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00{1,20})[^\x00]{9}(\x00{1,20}\x4D)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' IOAHCIBlockStorage
  7. OR for Mountain Lion 10.8.0 and Lion 10.7.4 BELOW
    # perl -pi -e 's|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00{1,20})[^\x00]{9}(\x00{1,20}\x51)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x00$2|sg' IOAHCIBlockStorage
  8. # touch /System/Library/Extensions/
  9. reboot your machine

In the system report (system information > serial-ata device) the TRIM support should list YES. The patch has to be re-applied everytime there's an OS update.

Locale problem in CentOS

Posted on by Andy

hello,

when executing some programs like bash, python, perl or yum you can sometimes encounter messages like these:

"-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8)"

or

"Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8""

The fix for this bug is quite simple, just add following line to your /etc/sysconfig/i18n:

LC_CTYPE="en_US.UTF-8"

and the world is nice again 🙂

Update:
If using the MacOSX Terminal you can also deactivate the option "Set locale environment…" in the Terminal -> Settings -> Advanced tab.
