How to manually turn on/off Xorg screen
Posted on May 2nd, 2012
It can be useful for example if you have a display that you need to be on for a period of time from 9-00 to 18-00 when you on desk.
I use that feature for Nagios management station which is running all the time but turn head display only when I’m on duty and can see what is on it.
nagios@nms-host$ crontab -l 0 18 * * * DISPLAY=:0 xset dpms force off 0 9 * * * DISPLAY=:0 xset dpms force on

Rebooting linux remotely when “reboot” command is not working
Posted on March 10th, 2012
If you got the system which cannot be rebooted traditional way for some reason (for example reboot command gives you “bus error”) you can use sysrq.
echo 1 > /proc/sys/kernel/sysrq echo s > /proc/sysrq-trigger echo u > /proc/sysrq-trigger echo b > /proc/sysrq-trigger
First command enables sysrq functionality, 2nd tries to sync filesystems, 3d to umounts them read-only (to avoid fsck during boot) and the last reboots the machine
Read Documentation/sysreq.txt in linux source directory for more options.

NetBackup: set exclude_list on Windows clients
Posted on November 30th, 2011
You need to set an exclude list for windows client using Unix Netbackup server.
# bpgetconfig -M win_client EXCLUDE EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\*.lock EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\bprd.d\*.lock EXCLUDE = C:\Program Files\Veritas\NetBackup\bin\bpsched.d\*.lock EXCLUDE = C:\Program Files\Veritas\Volmgr\misc\* EXCLUDE = C:\Program Files\Veritas\NetBackupDB\data\*
Then just append desired path to exclude and save the list back to client:
# bpgetconfig -M win_client EXCLUDE > /tmp/exclude_list.txt echo "H:\oracle\NWO\sapdata*" >> /tmp/exclude_list.txt # bpsetconfig -h win_client /tmp/exclude_list.txt

How to reset iLOM root password on Sun/Oracle X server
Posted on November 17th, 2011
if you’ve lost root password on Sun/Oracle X server, you can recovery it using ipmitool. This was tested on Sun X4600 M2, Solaris 10 installed.
# ipmitool user list 1 ID Name Callin Link Auth IPMI Msg Channel Priv Limit 1 false false true NO ACCESS 2 root false false true ADMINISTRATOR 12 radproxy true true true OPERATOR 13 ilomint true true true ADMINISTRATOR 14 ldapproxy true true true OPERATOR 15 pamproxy-admin true true true ADMINISTRATOR 16 pamproxy-oper true true true OPERATOR # ipmitool user set password 2 new-password
Now you can login using new-password.
