Random line

[mrn]

I'm writting a script to do an inital config of a HP-UX server, I've got to the NTP part and want to randomize the prefered server selection from 1 of 3 I.P's so all servers don;t have the same prefered NTP server.

I could do it with a count (1st IP, 2nd IP, 3rd IP) but wondered if anyone else could help with the random bit?

ok bit messy but could do this

a=`echo $RANDOM|cut -c 1`

if [ $a = "1" -o $a = "4" -o $a = "7" ]
then
IP1=192.168.1.1
elif [ $a = "2" -o $a = "5" -o $a = "8" ]
then
IP1=192.168.1.2
elif [ $a = "3" -o $a = "6" -o $a = "9" ]
then
IP1=192.168.1.3
fi

repeat for secondary IP

r=$RANDOM
IP1=$((  r%3    + 1 ))
IP2=$(( (r+1)%3 + 1 ))
IP3=$(( (r+2)%3 + 1 ))

I neglected to include the "192.168.1." part, but you get my drift...
