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

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”

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

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.

I made some performance charts from the output of sar and custom scripts, check them out!
http://www.kraftek.com/perf/
The source is in
http://www.kraftek.com/perfsrc/
open flash chart
and my own php/ksh scripts.

if you need to know where, for instance is “qfe0” in your e25k, so someone can connect a cable there… you can use sun
doc #202571, which i have transformed to a script called “pos.ksh”:
#!/bin/ksh
echo “Expander Slot Device”
grep pci /etc/path_to_inst |while read nic;do
A=`echo $nic | awk -F”@” ‘{ print $2 }’ | awk -F”,” ‘{print $1}’`
O=`echo $nic | awk -F”,” ‘{print $2}’| awk -F”/” ‘{ print $1 }’`
T1=`grep ” $A” t1.txt`
E=`echo $T1 | awk ‘{ print $2 }’`
C=`echo $T1 | awk ‘{ print $1 }’`
S=`grep “^$C…$O” t2.txt | awk ‘{ print $2 }’`
echo “$E $S $nic”
done
You will need t1.txt:
IOC Expander AgentID
0 0 1c(28)
1 0 1d(29)
0 1 3c(60)
1 1 3d(61)
0 2 5c(92)
1 2 5d(93)
0 3 7c(124)
1 3 7d(125)
0 4 9c(156)
1 4 9d(157)
0 5 bc(188)
1 5 bd(189)
0 6 dc(220)
1 6 dd(221)
0 7 fc(252)
1 7 fd(253)
0 8 11c(284)

0 16 21c(540)
1 16 21d(541)
0 17 23c(572)
1 17 23d(573)
and t2.txt
IOC Slot Offset
0 0 600000
0 1 700000
1 2 600000
1 3 700000
So basically, inside any given domain you can do:
#./pos.ksh > slotmap.txt
then, if you want to know where your Quad Fast Ethernet “qfe” cards are, you can do:
bash-2.03# egrep “qfe|Expander” slotmap.txt
Expander Slot Device
2 3 “/pci@5d,700000/pci@1/SUNW,qfe@0,1” 0 “qfe”
2 3 “/pci@5d,700000/pci@1/SUNW,qfe@1,1” 1 “qfe”
2 3 “/pci@5d,700000/pci@1/SUNW,qfe@2,1” 2 “qfe”
2 3 “/pci@5d,700000/pci@1/SUNW,qfe@3,1” 3 “qfe”
17 3 “/pci@23d,700000/pci@1/SUNW,qfe@0,1” 4 “qfe”
17 3 “/pci@23d,700000/pci@1/SUNW,qfe@1,1” 5 “qfe”
17 3 “/pci@23d,700000/pci@1/SUNW,qfe@2,1” 6 “qfe”
17 3 “/pci@23d,700000/pci@1/SUNW,qfe@3,1” 7 “qfe”
And you’ll find out you have 2 quads, one is at IOBoard 2 slot 3, the other is at IOBoard 17 slot 3
A typical IOBoard has 4 slots, numbered from 0-3,
|—–|—–|
| | |
| slot|slot |
| 3 | 1 |
| | |
| | |
|—–|—–|
| | |
| | |
| slot|slot |
| 2 | 0 |
| | |
|—–|—–|
118/433
So Both cards are at the upper left, one on IOBoard 2 the other on IOBoard 17
Qfe0 is at IOBoard 2 slot 3

If you get obfuscated about grub’s disk device numbering, in the grub prompt you can do:
“root (” + tab
like:
grub > root ( <press the tab key>
Possible disks are: fd0 hd0 hd1

When you want to run a vncserver session on a non-root user from a solaris sparc machine, it just ends with this
message:
_XSERVTransSocketCreateListener: failed to bind listener
After going around some places i found something to fix this at
http://www.webservertalk.com/archive100-2004-2-131777.html
That involves creating a script in /usr/bin/fixXdir.ksh and putting it at the crontab, like this:
#!/usr/bin/ksh
PATH=”
IFS=’ ‘
ice_dir=/tmp/.ICE-unix
x11_dir=/tmp/.X11-unix
for dirname in $ice_dir $x11_dir
; do
{
if (! [ -d $dirname ] )
then
/usr/bin/mkdir $dirname
if [ $? != 0 ];
then
/usr/bin/echo “Warning: $0: cannot
mkdir $dirname.”;
fi
fi
if ([ -d $dirname ] )
then
/usr/bin/chown root:root $dirname
if [ $? != 0 ];
then
/usr/bin/echo “Warning: $0: cannot chown $dirname.”;
fi
/usr/bin/chmod 1777 $dirname
if [ $? != 0 ];
then
/usr/bin/echo “Warning: $0: cannot chmod $dirname to 1777.”;
fi
fi
}
done
289/433
The crontab line is this:
0,5,10,15,20,25,30,35,40,45,50,55
/usr/bin/fixXdir.ksh

Needed to rename all directories and files in a deep directory structure to remove spaces and ugly characters in their
names, in order to build a playlist, take a look at this recursive bash shell:
#!/usr/bin/bash
DIR=/200gb/MP3
FTYPE=mp3
renamedir ()
{
cd
find . -type d -maxdepth 1 -name “??*” | while read d; do
DN=`echo “$d” | sed “s/&/And/g;s/-//g;s/ //g;s/(//g;s/)//g;s/[/
/g;s/]//g;s/’//g” | tr -s ‘_’`
if [ “$d” != “$DN” ];then
echo “— `pwd` $d”
mv “$d” $DN
fi
renamedir
$DN
cd ..
done
}
echo ” —- Recursively clean directories”
renamedir $DIR
echo ” —- Now clean files”
cd $DIR
find . -type f -iname “*.$FTYPE” | while read f;do
FN=`echo “$f”| sed “s/&/And/g;s/-//g;s/ //g;s/(//g;s/)//g;s/[//g;s/]/
/g;s/’//g” | tr -s ‘_’`
if [ “$f” != “$FN” ];then
echo “— $f”
mv “$f” $FN
fi
done
echo “done.”
