Hi all, I'm pretty new to CentOS. I am working with a newly set-up server: [cbearden at host ~]$ lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.3 (Final) Release: 6.3 Codename: Final I'm trying to solve this problem (X11 forwarding) http://thread.gmane.org/gmane.linux.centos.general/119342/focus=119347 for myself. But disabling ipv6 and adding AddressFamily inet to my sshd config didn't fix the problem. Oddly enough, the output of netstat -an suggests that ipv6 is still enabled: tcp 0 0 :::22 :::* LISTEN even though [cbearden at PostgreSQL ~]$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6 1 This is after a reboot. Am I right that the /proc file suggests that ipv6 is disabled while netstat suggests that it isn't?
