Ken, I first setup webmin on the server - this listens on port 10000 by
default (https).
Then from a remote location I can
ssh servername -L 8081:localhost:10000
This will capture local port 8081 and tunnel to the remote server port
10000.
Then with firefox I enter https://localhost:8081/
and I get the remote server's webmin.
HTH
