ssh tunnelling

On the receiving server edit the /etc/ssh/sshd_config file. Replace AllowTcpForwarding yes. restart sshd (or reboot) for this setting to take effect.

On the receiving server say
ssh -L:localhost: @ -N

On the sourcing/originating/'client' machine say
sh -L:localhost: @ -N

Now you can use any tool on the 'client' machine as though the server is running locally - only caution is to know that you have to use the credentials of the remote machine as needed. For example, if you want to use MySQL query browser on the client, you have to give the credential of the username of the machine on which the MySQL server is running. This will be the machines account - not mysql account.
