I've gotten PPP to work using dynamically assigned IP addresses and
hostnames, but I'm wondering how to automatically change my hostname to
the dynamically assigned name once the connection is up. I need to do
this because some e-mail servers that I use insist on knowing my real
hostname. If I make something up, those servers reject mail from me on
the basis that my machine needs to have a real name and domain. Thanks
for any info!
