Hi,

Is it possible to redirect network port traffic from the port of one mac to another port on a different machine??

Trying establish secure port connections, ssl, and such.. but for now, just trying to redirect the port 24/7. So if the user disconnects, the port stays open for him to reconnect. I've done this in java believe that there has to be a way to do this in unix..

thanks
tim

It's easy to setup port forwarding using SSH, so that ports are forwarded while the SSH session is open.

ssh -R host_port:target_host:target_port host

will open a SSH session to machine 'host', and instruct it to listen to port 'host_port'. Any connections to 'host_port' are forwarded to port 'target_port' on machine 'target_host'.

so

ssh -R 8080:www.apple.com:80 home_ip_address

will connect to the machine at home_ip_address. Connecting to http://home_ip_address:8080/ will proxy the request to www.apple.com:80

Setting up a permanant port forwarder involves running some kind of proxy service on your machine. Certainly possible, and may be easier for you - it depends on whether you want the port to be open all the time or just at specific times you control (by opening a SSH session to the machine)

Very cool, your example worked great..

never would have thought that ssh had such a feature built in.
How do I turn that off, or change the ip address it goes to? if I try to execute the function twice, it says that the port is already open.

So it can do web traffic.. if the web site forwards to a secure port, does it keep transmitting through the port 80 connect?

Thanks
