Hi, I am using SSH to do X forwarding and saw an interesting problem: for some applications, even when I closed the application itself, the SSH session is still not closed. For other applications, SSH sessions closed whenever I closed the application. For example, if I do: ssh -X <host> xclock then I close the xclock app, the ssh session exits. but if I do: ssh -X <host> firefox then I close the firefox app, the ssh session does not exit. In the latter case, I can see the corresponding sshd process is still running at <host>. Is such behavior caused by the application? any insights are appreciated. my SSH version is: OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g thanks Han
