I wanted to generate a call from a script, and deliver a voice message, through a DAHDI channel, to a pots line.
This class does it, it tells you in the end if the line was busy, if it was never answered or if the call succeeded.
This is, if you trust dahdi callprogress, which is really broken… this example works better for SIP calls.

To add an hagui admin user you do:
# haconf -makerw
# hauser -add rdircio
# hauser -addpriv rdircio Administrator
# haconf -dump -makero

You basically get “/bin/sh: scripts/basic/fixdep: No such file or directory”
Using 2.6.x kernel build system.

If you don’t have a .config file in your kernel source you can:
# make cloneconfig
Then it might complain that
“scripts/modpost: No such file or directory”
So you just copy it according to the kernel you’re running:
89/433
# uname -a
Linux imdalapp300b 2.6.5-7.314-smp #1 SMP Mon Sep 15 16:43:00 UTC 2008 i686 athlon i386 GNU/Linux
# cp /usr/src/linux-2.6.5-7.314-obj/i 386/smp/scripts/modpost /usr/src/linux-2.6.5-7.314
Now you can run again “vmware-config-tools.pl”

I’ve written a detailed procedure on how to migrate a server using SAN disks as intermediate storage.
Read it!
it is fun.

# cp /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.annotated /etc/multipath.conf
# chkconfig –add multipathd
# chkconfig multipathd on
# reboot
For each lun assigned to you a device under /device/mapper will apear, do a fdisk to each one:
# fdisk /dev/mapper/360060e80047656000000765600000e43
# fdisk /dev/mapper/360060e80047656000000765600000e44
# fdisk /dev/mapper/360060e80047656000000765600000e45
# fdisk /dev/mapper/360060e80047656000000765600000e46
# fdisk /dev/mapper/360060e80047656000000765600000e47
# fdisk /dev/mapper/360060e80047656000000765600000e48
# fdisk /dev/mapper/360060e80047656000000765600000e49
In each case do a “p” and then a “w” to overwrite the volume label, you will have to restart the server.
# reboot
Once back, open the lvm assistant:
# /usr/bin/system-config-lvm
once there initialize each block device found at:
# ls /dev/dm*
after that you can create a volume group and volumes 🙂

A good practical command to take a look on how your TSM jobs are running is to use:
# egrep -i “Schedule Name|Finished” /var/tivoli/dsmsched.log

To check kernel set open files limit
% cat /proc/sys/fs/file-max
8192
To increase kernel set to 65535 (as root)
# echo “65535” > /proc/sys/fs/file-max
If you want this new value to survive across reboots add it to /etc/sysctl.conf
fs.file-max = 65535
You can load these values live from the sysctl.conf file.
# sysctl -p /etc/sysctl.conf
The previous settings will only be for root, we need to adjust some files for all
the users to have them inherited.
To increase this to 65535 for all users (as root)
add two lines to /etc/security/limits.conf
kraftek.html POSTS rescue rescued.html rescued.txt x y z soft nofile 65535
kraftek.html POSTS rescue rescued.html rescued.txt x y z hard nofile 65535
Now add the next entry to /etc/pam.d/login
session required /lib/security/pam_limits.so
Relogin as your non-root user and check the new file open limit with:
$ ulimit -n

If your HP rilo,rib,ilo card (i don’t get these names) is not accessible, and the server is booted up to linux, you can
configure its address using “hponcfg”
theserver:~ # hponcfg -f rdpm.xml
Firmware Revision = 1.91 Device type = iLO Driver name = cpqci
Script succeeded
Where rdpm.xml has contents:
<RIBCL VERSION=”2.0″>

Still on the performance+sysstat topic, I found useful to use “sar -ruq” to obtain memory, cpu and runqueue stats in one
command

Nmon
To add to our previous performance post, we can equip our linux server with nmon, from IBM.
I’m not an IBM fan, this is free, but closed source!!!, despite this, it looks good, get it at:
