Well, I currently use /etc/ppp/ip-up.local to:

  install specific ipchains rules
  change my hostname to the correct one for the IP address I have been given
    (a little shell scripting does it)
  restart sendmail
  fix my /etc/resolv.conf
  restart fetchmail

What I wanted was something similar for when an ethernet interface comes up.

If you look at /sbin/ifup on RedHat, Mandrake or any RedHat derived distro,
you will see that it invokes /etc/sysconfig/network-scripts/ifup-post. The
last thing this last script does is invoke /sbin/ifup-local, if it exists
and is executable. (if [ -x /sbin/ifup-local ] ...)

It passes the device name to the script. So, if eth0 has come up,
/sbin/ifup-local will be called as:

  /sbin/ifup-local eth0

You can then do all sorts of magic in the script ...
