How to delete SMS messages from SIM card with SHR, freesmartphone.org, GTA02

Posted on November 6th, 2012

Once you get a message that your SMS storage on SIM is full and you can’t receive any messages. So, you have to clear your SIM from old messages.
In this example we are using GTA02 device with SHR as of 20120730233813.
First, we open a freesmartphone docs on SIM API and have some fun.

root@om-gta02:~# mdbus2 -s org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device  org.freesmartphone.GSM.SIM.GetSimInfo
({'slots': <20>, 'imsi': <'XXXXXXXXXXXX'>, 'issuer': <'unknown'>, 'used': <20>, 'phonebooks': <'emergency aux:BD fixed aux:DC dialed received aux:LR aux:MT aux:AD contacts aux:SD missed aux:LM aux:AF own aux:UD'>},)

So, we are going to purge 20 messages as we have used 20 of 20 slots.
But if you want to read them first, issue the command

root@om-gta02:~# mdbus2 -s org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.SIM.RetrieveMessage 1
('read', '1095', 'this is a private sms message', {'pid': <byte 0x00>, 'sri': <false>, 'rp': <false>, 'udhi': <false>, 'mms': <false>, 'dcs': <byte 0x01>, 'udl': <byte 0x46>, 'timestamp': <'12/11/06,16:16:24+16'>})

When done, delete it.

root@om-gta02:~# mdbus2 -s org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device  org.freesmartphone.GSM.SIM.DeleteMessage 1

Next call to GetSimInfo wil show ‘used': <19>.

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

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
