Hi !

Since my ISP is a big m*thfscker sun of a beach, im trying to forward a remote port to home. Im login from home to the remote host like

ssh -g -R 10000:home.addr.ip.mine:20000 remote.host.forward.net

ok, im assuming that this is going to:

each connection into remote.host.forward.net:10000 will be forwarded directly to my home.addr.ip.mine:20000. Is this correct?

so i can intended to connect to home from anywhere like

ssh remote.host.forward.net:10000

and welcome home, isnt it?

anyways, when i try this i get the following error:


ssh_exchange_identification: Connection closed by remote host


what this error means? thansk a lot!

From memory - try:

maybe i have to say to sshd at home to listen at 20000? or is this handled directly by the forwarding command?

I assumed that you already had the required srevice running on port 20000? What service are you trying to run? ssh? To check if it is running on port 20000:
netstat -nlp | grep 20000

If it isn't then you need to add a Port option for all ports you want sshd to listen on to sshd_config and restart sshd- eg:
Port 22
Port 20000

yippie!


thanks!!

in order to forward ports also for http, sftp, etc.. must i do this for each desired service, or can i handle it somehow to forward any connections to port 10000 to the intended address (which would be my home address) with subport information that would connect to a specific service in home?

dunno if that even makes sense hopes someone understand what im saying, but maybe this is simply not possible

If you want to do it via ssh you need to forward each port individually.

what other ways are to forward ports, besides ssh?

You can use iptables to forward ports too but they aren't encrypted.
