You can connect to her machine remotely via ssh . . . very similar to telnet but strongly encrypted. You can install programs for her via the command line and even run X11 applications via x-forwarding.

(of course, ssh, both client and server, are included with slackware. Just "chmod 755 /etc/rc.d/rc.sshd" as root to ensure that the server is started at boot time.)
Edit the file /etc/ssh/sshd_config on your mother's machine. Make sure that the line . . .
is present.
Post your mom's IP with
www.no-ip.org or some similar service.
Now, you can ssh into your mom's box from your machine with a simple
Code:
ssh username@host.domain.com
command. Or,
Code:
username@197.45.223.12
if you don't set up a hostname.
Either way, if you plan on invoking any GUI apps, you'll want to give her machine permission to create windows on your display before you ssh over there with a command like . . .
Code:
xhost + your.moms.IP.or.domain.name
If you don't include a username, and just use the command 'ssh host.domain.com', you'll be logging straight in as root.
I hope this helps . . .
Of course, there's always the old phone tech support method. Hehehe
