Hi I downloaded 2.6.9-1.11_FC2smp in early January but have only just tried it. Previously the box was in FC2 but using various bespoke 2.4 kernels although 2.6.8-1.521smp had been used without problem. Booting this kernel has switched sshd into dual-listen mode so that all IP numbers are reported as ::ffff:n.n.n.n. This makes a monkey of my BF protection as the apf firewall doesn't parse it correctly. When I boot back into 2.4, sshd mode is retained in dual-listen, despite being dropped on bootup. I have explicitly switched ipv6 off in /etc/sysconfig/network but this problem is still there. (NETWORKING_IPV6=no). IPV6 is enabled in the 2.4 kernel by modules but none of them are loaded. Can someone tell me please how do I stop sshd from working in dual-listen mode?
