Peter,
Thanks for the reply.
I waited to respond until I had a chance to sit down and
mess with this.
I went into this with the understanding that I can use
the dhclient-script file to run my own scripts in.
I tried and experiment to see if I can get a simple test script to run
and I haven't had any luck.
In dhclient.conf I added :
interface "vr0" {
script "/etc/dhclient-script";
}
In dhclient-script I added
echo 'this is a test' > testecho
dhclient-script had permissions 744
My output was:
# sh /etc/netstart
execve (/etc/dhclient-script, ...): Exec format error
exiting.
DHCPREQUEST on vr0 to 255.255.255.255 port 67
DHCPACK from 67.236.64.1 (00:30:88:03:62:b5)
bound to 67.236.124.195 -- renewal in 1800 seconds.
AM WRONG in the idea that I can run shell scripts in
dhclient-script?
My idea had been to run
# ifconfig vr0 > presentIP
then email presentIP back to me.
thanks, Ed
