You might try the following. Determine the Windows pid of your sshd process, then use netstat to see if that process is listening on the sshd port. Here's what a successful check looks like: ~ ps -as|grep sshd 42834 ? Jan 16 /usr/sbin/sshd ~ ps -lp 42834 PID PPID PGID WINPID TTY UID STIME COMMAND 42834 42832 42834 5972 ? 197612 Jan 16 /usr/sbin/sshd ~ netstat -ao|grep 5972 TCP 0.0.0.0:22 zotac:0 LISTENING 5972 TCP [::]:22 zotac:0 LISTENING 5972 If the two output lines aren't there, I'd suspect a Windows firewall has TCP port 22 walled off. ("zotac" is my machine name; you'll see something different there.)
