Thread: TCP_NODELAY - Problem with Reverse SSH Tunnel

trying reverse ssh tunnel going mac osx 10.6.6 ubuntu server 11.04 .

on mac use following command:
ssh -r 19999:localhost:22 user@remoteip

on server use:
ssh localhost -p 19999

on server following message in terminal:
identification: connection closed remote host

on osx following message:
setsockopt tcp_nodelay: invalid argument

can't tell if issue osx or ubuntu. ideas or thoughts great.

just clear command means,

listen on port 19999 on localhost on remoteip machine , forward connections mac on localhost port 22.

before connect localhost port 19999 on server need have listening on mac on localhost port 22. presumably want sshd doing need make sure case. on mac can run "sudo netstat -lntp" check sshd (or whatever want) listening on localhost port 22.

can check on server ssh indeed listening on port 19999 using same command. default listens on localhost , not on "*" (any interface). can connect within server itself, not external location. in order connect remotely server:19999 need override config of ssh on server gatewayports option.
