That will only be echoed to the console.

No there is no need to touch anything in sendmail, simply pipe the output to
"mail" like.
/sbin/ifconfig ppp0 | grep inet | awk '{print $2}' | cut -f2 -d: | mail
host@machine
Be careful when using 'cut' and awk together as sometimes fields can shift,
which "could" result in the wrong information being gained, or at worst no
info will be shown. Simply do ifconfig ppp0 | mail host@machine
On the otherhand i ask myself why all this is nessacary.? I presume by
reading the message that the users of that machine have physical access, all
they need to do under normal curcumstancies is just hit the ctrl-alt-delte
keys simultainiously which will reboot the machine, then at the lilo prompt
the user just types windows or whatever the keyword is for booting into that
particular system.
Having LILO boot Linux as default will result in Linux being booted upon
leaving windows.
Surely if everyone is on campus then there would be a local LAN, so if the
owner was on the otherside of campus, then all he would need to do is telnet
to his hostname, but i might be taking to much for granted by saying that.
