Hi Salva,
Ssh is a very fine tool for port forwarding. Core Server Slime REPL server
usually listens 127.0.0.1:4005 which is stated in
~/core-server/etc/start.lisp.
(FUNCALL (FIND-SYMBOL "CREATE-SERVER" (FIND-PACKAGE 'SWANK)) :PORT 4005
:DONT-CLOSE T)
which should be read as:
(swank::create-server :port 4005 :dont-close t)
This link
http://www.ssh.com/support/documentation/online/ssh/adminguide/32/Port_Forwarding.html
discusses ssh port forwarding.
ssh -L 4005:localhost:4005 user...@core-server.net
command will make all connections to your local 4005 forwarded to remote
boxes' 4005. So you can connect via
M-x slime-connect
Host: 127.0.0.1
Port:4005
Evrim.
