What about her linksys router? does IT allow port 22 traffic
in and out?

And your machine? Is IT on a router? If yes, have you check
the router to see if it has a firewall that does not allow port 22
I am really suspecting only firewall issues, and not F13 issues.
Changing the port number on which your sshd daemon listens
could work if some firewall is blocking port 22 traffic.
You change the sshd port number by editing

In /etc/ssh/sshd_config you will see lines like:

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a
# default value.

#Port 22
#AddressFamily any
#ListenAddress ::

Uncomment Port 22
and change it 22 to say ... 2222

and restart your sshd.

On your sister's machine, ssh to your machine like so:

ssh -p 2222

and let us know if that worked.

If it does work, then your problem is indeed a firewall setting.

Good luck.
