Are you connecting as a specific user from the external network. If
your logged in username is the same as the SSH valid username then you
are ok. If you are using the same username on all your machines
internally (or at least the same username on your SSH box and the one
you are using to connect with) then that would work no problem. But
if you are trying to connect and your username is one not found on the
FC5 SSH server, it will not work. You must specify the username. I
am wondering if you are trying to connect externally under a username
not found on the remote machine (and you are not specifying a specific
username to connect as). That would not work.
Example: Your FC5 SSH server has users john, mary, steve, and paul.
You are logged in on your remote machine as john. When you issue the
command ssh xxx.xxx.xxx.xxx it will try and connect to your SSH server
using the username john and prompt you for that username's password.
Where that is a valid username on the SSH server, it works. But if
you are logged in as nancy for example, then it won't work. You have
to use the command:
ssh username@xxxxxxxxxxxxxxx
where username is a valid user on the SSH server. Of course you can
do this even when logged in as john for example on your local machine
but you want to ssh to the user mary on the remote server. Then you'd
issue
ssh mary@xxxxxxxxxxxxxxx
Telnet would still provide the output you experienced above (but it's
an excellent tip to remember to check if a port is listening).
If you are already doing this then disregard my suggestion. Maybe it
will benefit someone else.
