Other people have mentioned console tools so I won't bother.

But did you know that with ssh access you have access to every port on the 
remote machine?

SSH(1)

  -L [bind_address:]port:host:hostport
          Specifies that the given port on the local (client) host is to be
          forwarded to the given host and port on the remote side.  This
          works by allocating a socket to listen to port on the local side,
          optionally bound to the specified bind_address.  Whenever a con-
          nection is made to this port, the connection is forwarded over
          the secure channel, and a connection is made to host port
          hostport from the remote machine.

ssh -L 8080:localhost:80 your-nagios-box

http://localhost:8080/

So here you're hitting port 8080 on your desktop machine and the packets 
are getting sent over your SSH connection to the HTTP port on the nagios 
server.

If the HTTP server on the nagios box isn't bound to localhost you'll have 
to specify (in the ssh command) the hostname or IP that it is bound to.
('netstat -tnl | grep :80' can help you find out)

Windows ssh clients such as PuTTY can also do port forwarding.
