Configuring services for unusual ports

How would I go about configuring my xinetd's kr5-telnet server on my red hat
Linux 8.0 box to respond to a port other than the standard port 23? (As you
can see from my signature file below, I've already got port 23 on my network
being answered by a different machine.)

I'm getting ready to take a trip and will need to be able to remotely access
my machine while gone, but my laptop doesn't have a SSH client on it. My
firewall already blocks or forwards all the ports that I might use except
for an odd one that I have open for another service that will not be running
during this time. Any help on this will be greatly appreciated. (I did check
the man pages and info pages without luck, though I don't mind reading them
if someone can point me to one that will answer this.) You may also be able
to tell by now that I'm fairly new at Linux, if you need more info to be
able to answer this, please let me know.

I apologize for the cross-posting, but I'm hoping that by including a single
newsgroup for follow-up this post may get seen by enough people to get an
answer for me reasonably quickly while not spamming a bunch of newsgroups,
if I've done this wrong, I'll take the flames that I know some folks are
just dying to dish out without complaint.

I can't offer any suggestions about configuring xinetd but as for an ssh
client how about putty? There are both Windows and Linux versions around,

I could try putty, that would give me the ability to use ssh instead of
telnet, but I still really need to be able to set up the service in
question, be it telnet or ssh, to listen to a non-standard port as ports 22
and 23 are not available to me for this "project". :(

SSH allows you to do this :)

In the config there is a line specifying the port to listen on. This
defaults to "Port 22", you just need to change it to your non-standard
port.

I'm not sure where the config is located in RedHat but in Debian it is:
/etc/ssh/sshd_config.

I'll check there and see if it's the same, hang on... it is! Ok, I changed
that and restarted sshd, it seems to work, now I have to find putty and
install it so I can see if it actually works, eh?
