To get music-on-hold from a live source, i made a script (/scripts/streamx.ksh):
#!/bin/ksh
/usr/bin/ogg123 -q -b 128 -p 32 -d wav -f – http://kraftek.com:8000/stream.ogg| sox -t wav – -r 8000 -c 1 -t raw
- vol 0.10
27/433
and configured /etc/asterisk/musiconhold_additional.ksh with:
[default]
mode=custom
application=/scripts/streamx.ksh
And that is it!, just dial a conference room and you’ll get live music on hold while waiting for your friends to
join

Use the queryformat modifier to print more info about your rpm
# rpm -qa –queryformat %-{name}-%{version}-%{release}-%{arch}”n”
You can grep for something there, because it is a full listing

/dev/systemvg/swapvol (deleted) partition 4095992 0 -3
According to http://kbase. redhat.com/faq/FAQ_79_4331.shtm we need to
add “swapoff -a && swapon -a” to the end of /etc/rc.d/rc. sysinit
We can also run
#swapoff -a && swapon -a
To fix it live, and we’ll see:

If your slice 2 is empty and you got partitions 0-9 in your disk when checkign it in “format”, you have an EFI label.
If you want to change it to a SMI label, you need to use “format -e” and when prompted for the label type,
choose SMI
partition> label
[0] SMI Label
[1] EFI Label
Specify Label type[1]: 0
Warning: This disk has an EFI label. Changing to SMI label will erase all
current partitions.

I already have a script like this in “miniexplorer”, but it generates html and that may be overkill, so this is a quickie one to
query all network card ports in your solaris server about NIC speed.

Say you want a random Gnome wallpaper from google each 60 seconds, but if your machine is not connected, just take
the backdrop from a local directory ~/Desktop/backdrops. you can put up a couple of scripts to do this, the main one
would be /scripts/changewall.ksh
#!/bin/bash
mkdir -p /tmp/wallpapers
E=`ps -ef | grep -i changewall | grep -i $USER | grep -iv grep | wc -l`
if [ $E -gt 2 ];then
echo “wallpaper changer already running for $USER”
exit 1
fi
i=120
while true;do
i=`cat /scripts/time.txt`
rm -fR /tmp/wallpapers/*
RANGE=10
number=$RANDOM
let “number %= $RANGE”
number=$(($number))
ping -w 10 -c 2 www.google.com > /dev/null 2>&1
R=$?
if [ $R -eq 0 ] && [ $number -lt 9 ];then
/scripts/wallpaper.ksh > /dev/null 2>&1
F=`ls /tmp/wallpapers`
N=`echo $F | wc -c`
if [ $N -gt 1 ];then
gconftool-2 -t string -s /desktop/gnome/background/picture_filename “/tmp/wallpapers/$F”
# cp “/tmp/wallpapers/$F” $HOME/Desktop/backdrops/
else
cd $HOME/Desktop/backdrops
ls -1 *.jpg | head -n`expr $RANDOM % \`ls -1 *.jpg | wc -l\“ | tail -n1 | echo `pwd`/`xargs` | gconftool-2 -t string -s /desktop/gnome/background/picture_filename “`xargs`”
fi
else
cd $HOME/Desktop/backdrops
ls -1 *.jpg | head -n`expr $RANDOM % \`ls -1 *.jpg | wc -l\“ | tail -n1 | echo `pwd`/`xargs` | gconftool-2 -t string -s /desktop/gnome/background/picture_filename “`xargs`”
fi
sleep $i
done
Then you would need the support script, to get images from google according to a random word that comes
from /scripts/wallpaper-subjects.txt program: /scripts/wallpaper.ksh
#!/bin/ksh
cat /scripts/wallpaper-subjects.txt | head -n`expr $RANDOM % \`cat /scripts/wallpaper-subjects.txt | wc -l\“ | tail -n1 > /tmp/subject
QUERY=`cat /tmp/subject | sed ‘s/ /%20/g’`
RANGE=10
number=$RANDOM
let “number %= $RANGE”
number=$(($number + 1))
IMG=`curl -m 10 -A “Mozilla/3.0 (compatible; AvantGo 3.2)” “http://images.google.com/images?as_q=${QUERY}&as_filetype=jpg&biw=1680&bih=1024&safe=active&as_st=y&tbs=isch:1,itp:photo,islt:2mp,isz:l,ift:jpg” 2>/dev/null |sed -e ‘s/>/>\n/g’ | awk ‘{s=substr($0,index($0,”http”),index($0,”jpg”));print substr(s,1,index(s,”.jpg”)+3)}’ | grep jpg |egrep -v ‘starkeith|gstatic|scaredmonkeys|tripod|flickr’|sed ‘s/2520/20/g’ | head -$number | tail -1`
mkdir -p /tmp/wallpapers
cd /tmp/wallpapers
wget –timeout=10 $IMG
you can add /scripts/changewall.ksh to your autostart stuff in gnome, going to system –> preferences –>
startup applications
ENJOY!

if you need to make a copy of your boot disk, and you don’t have
disksuite, and you only have one slice as “/”, and this is solaris 10,
you can do:
#prtvtoc /dev/rdsk/c0t0d0s0 | fmthard -s – /dev/rdsk/c0t1d0s0
#newfs /dev/dsk/c0t1d0s 0
#mount /dev/dsk/c0t1d0s0 /a
#cd /
#find . -mount | cpio -pmdv /a
#installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0
#vi /a/etc/vfstab
(change references from c0t0d0s0 to c1)
#mkdir /a/tmp
#mkdir /a/dev
#mkdir /a/proc
#touch /a/etc/mnttab
#mkdir /a/etc/svc/volatile
#mkdir /a/system/object
#mkdir /a/system/contract
#umount /a
#init 0
#boot otherdisk -r
And the system will boot fine from the other disk.
Remember it should be better to do this in single user mode, and with apps down.

This is basic ssh port forwarding, but i always forget…
so, you have hosta, hostb and yourpc.
you’re not in the same network as hostb, so you need to connect this way
yourpc –> hosta —> hostb
and you have a vnc session at hostb:1 (5901)
you want to connect to hosta:11 (5911) and get your vnc screen at hostb:1 (5901)
All you have to do is, from hosta
rdircio@hosta $ ssh -g -C hostb -L 5911:localhost:5901
then point the vnc client on yourpc to hosta:11.

if you get that error while trying to boot from a USB disk, and you’re 100% sure it is the right disk and partition, then
pass:
rootdelay=10
to your grub parameters. That will make the kernel wait a bit until your usb drive appears.

You want to know for the latest N days who was able/unable to su, in solaris. Sulog is in /var/adm/sulog, and we don’t
have the niceties of GNU date, so we use perl inside a shell… “suentries.ksh”
#!/bin/ksh
#— n has how many days ago we want
n=$1
today=`/usr/bin/perl -e ‘printf “%dn”, time;’`
x=$n
while [ $x -gt -1 ];do
ago=$(($today-86400*${x}))
export ago
DAY=`perl -e ‘($a,$b,$c,$d,$e,$f,$g,$h,$i) =localtime($ENV{‘ago’});printf”%02d/%02dn”,$e+1,$d’`

to unpack on the fly:
# gunzip < filename.tar.gz | tar xvf -
to pack on the fly:
# tar cvf – files_to_tar | gzip -c > filename.tar.gz

If sendmail starts only using local.cf and something like this appears:
# ps -ef | grep -i sendmail
root 22616 1 0 11:13:11 x y z 0:00 /usr/lib/sendmail -bd -q15m -C /etc/mail/local.cf
smmsp 22614 1 0 11:13:10 x y z 0:00 /usr/lib/sendmail -A
And you want it not to run only local, you can do:
# svccfg -s svc:/network/smtp:sendmail setprop config/local_only = false
# svcadm refresh svc:/network/smtp:sendmail
# /usr/bin/svcprop -p config/local_only svc:/network/smtp:sendmail
false
# svcadm disable sendmail
# svcadm enable sendmail
And now it runs without local.cf
# ps -ef | grep -i sendmail
root 24465 1 0 11:18:13 x y z 0:00 /usr/lib/sendmail -bd -q15m
