If you can connect locally, but not remotely, it has nothing to do with
power management.  It could be a firewall problem or the ports may be
blocked somewhere.

Really,

Have you heard of a program called nmap well it has indicated to me that all
the ports used for the services I connect to are open. And unless RedHat 7.0
installs a firewall automatically.... I think your theory holds no ground
whatsoever. Does Caldera install a firewall automatically I highly doubt it.

Where are you running nmap and where are you trying to access home
from?  If trying to access your home computer from a corportate network,
you may find many ports are blocked.  Some cable companies also block
some ports.  Without further info, it's hard to say where the problem
lies.

As for Redhat, if a service is available locally, it has to be available
remotely, unless something in between is blocking access.  As I
mentioned, that could be a firewall, at either end or be blocked by the
cable company.  What's between that RH box and your ISP?  Have you tried
using different port numbers?  Are you trying from work?  Can you access
other systems?

Hi Andrew,

What sort of message are you getting when you try to connect to the services. 
Is it a case of connection accept and then the connection is closed, 'no route
to host', or just nothing happens.

If you get a connection and then it closes, you might like to check your tcp
wrappers (/etc/hosts.allow and /etc/hosts.deny) and make sure that you are
permitted to connect from that host without any problems.  If you get a 'no
rote to host' then it might be the result of a network error in existence
between the network that the machine is on that you are trying to connect from
and the machine at the remote end, and if it is a case of your packets going
no where, then I would think that for some reason there is a firewall which is
preventing you access from your box.

If you can provide some more information about the behaviour that you are
getting, it should help us track down the problem.

See ya

The hosts.* are setup correctly for remote access ?
