[Uaflug] Need 'mail' help.

[Dayne Broderson]

You probably need to configure the box to had the mail to your mom's ISP. 
They should have an SMTP server, and that is what you'd have to configure 
the box to use for mail delivery.

You could do the scp using ssh-keys so it doesn't prompt for a password.. 
but I'd avoid that.. since that would be passwordless keys to your account 
sitting on a machine you don't fully control.

A better option would be to write a tiny little CGI/php app on Mod0 that 
allowed a machine to submit its 'name' and 'ip'.  Then have it store that 
for you to go and check to see what IP that machine's name is.

Another option is to get a dynamic DNS provider and setup their script.. 
then just use that domain name.  Might have to tweak the script to pull 
the IP from your script instead of ifconfig.
