I can forward port from Cygwin to Debian: cygwin# nc -l -p 6000
debian1# ssh -L 7000:cygwin.host:6000 u...@cygwin.host debian2# telnet localhost 7000 But if do same in inverse direction I got: debian# nc -l -p 6000 cygwin1# ssh -L 8000:debian.host:6000 u...@debian.host bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 8000 Could not request local forwarding. I don't understand what this mean... netstat under Cygwin is Windows utility: debian# netstat -l -n | grep 6000 tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN cygwin2# netstat -n -a -n TCP 127.0.0.1:8000 0.0.0.0:0 LISTENING 2308 [ssh.exe] Note that ssh.exe is not "ssh -L" but that I run to connect to debian.host for "nc -l -p 6000". To resolve issue I comment this line in ~/.ssh/config: # ControlPath ~/.ssh/sock_%r@%h_%p # ControlMaster auto -- Best regards! -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
