Description of problem: X11 forwarding doesn't function with IPv4 by default Version-Release number of selected component (if applicable): openssh-3.9p1-8.RHEL4.12 How reproducible: Steps to Reproduce: 1. Make entries in /etc/ssh/sshd_config: X11Forwarding yes X11UseLocalhost no 2. restart sshd, e.g., sudo /etc/init.d/sshd restart 3. attempt to start an X client Actual results: Client gets "connection refused". Netstat -tan shows tcp 0 0 :::6010 :::* LISTEN Expected results: Client get successful connection. Netstat -tan shows tcp 0 0 0.0.0.0:6010 0.0.0.0:* LISTEN Additional info: Successful workaround: in /etc/sysconfig/sshd, put OPTIONS=-4
The problem is not with the :::6010 output but with the fact that sshd sets incorrectly IPV6_V6ONLY socket option on the socket.
