[Uaflug] Need 'mail' help.

[Erik Gregg]

I recommend the dyndns option.  I have a little apt installable daemon on my
laptop that refreshes the entry rura-penthe.ath.cx with my current IP.  That
way, if it's ever stolen, I have a name to watch the trail of if the machine
goes online at any point.

hank at rura-penthe ~ $ host rura-penthe.ath.cx
rura-penthe.ath.cx has address 66.223.247.194

It's very nice.  Get the package ddclient.  Then, set up your
/etc/ddclient.conf like this:

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf

pid=/var/run/ddclient.pid
protocol=dyndns2
use=web
server=members.dyndns.org
login=<your login>
password='<your Password>'
<your dynamic name>

Where my dynamic name is rura-penthe.ath.cx.  Then, just run ddclient as
root.  It also has an initscript in /etc/init.d/ddclient.  You can use this
to schedule your updates.  There's a ton more information here:

http://ddclient.sourceforge.net/?page=1

Good luck.

- Hank
