VNC ssh tunneling problem: getsockopt TCP_NODELAY error
Figured I'd start with my FreeBSD friends first before bugging the VNC community. I used to have VNC tunneling over ssh just fine, but then had to redo my system drive. I used FreeBSD 5.1 before and still do now, however it's not working. I'm using the same PuTTY system so the config is the same as from before when it worked. So something is different at the FreeBSD end. The PuTTY log shows: 2003-09-04 11:26:28 Opening forwarded connection to localhost:5901 2003-09-04 11:26:28 Forwarded connection refused by server And /var/log/messages shows: Sep 4 11:26:28 scott sshd[37213]: error: getsockopt TCP_NODELAY: Connection reset by peer Maybe I'm just dumb and missed something I configured before, but I can't figure out what.
