<br></div></blockquote><div><br>Apparently you can still bind a socket to IPv6 even if it is turned off with sysctl - see this <a href="http://askubuntu.com/a/381623/254957" target="_top" rel="nofollow" link="external">http://askubuntu.com/a/381623/254957</a> and similar stories about sshd etc. Maybe unloading a kernel IPv6 module (if it is compiled as a module) would help but I do not need it so much to mess with my server's kernel.<br>
