Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I just set up IPv6 on Debian Squeeze on a hosted root server. Since I rebooted I can't connect to the server anymore. Ping is fine, but HTTP and SSH won't work. When I try to connect with SSH using the domain name I get "No route to host", when I use the IP I get "Connection refused". I think it has to be some DNS problem due to the different error messages. Perhaps wrong AAAA records or the reverse domain for IPv6 is wrong (which is the same as IPv4)? Any help would be appreciated.

So you can't ssh in via either IPv6 or IPv4? You're in trouble... –  Michael Hampton Nov 15 '12 at 1:58
I used the rescue system to get access to the hard disk and removed the IPv6 interfaces and tried to roll everything back, but nothing helped –  Flexx Nov 15 '12 at 2:01
If you even can't connect with ssh to the IPv4 address directly then something else is wrong which has nothing to do with IPv6. Probably some firewall filtering... –  Sander Steffann Nov 15 '12 at 6:39
paste the output of "ip addr", "ip route" and "ip -6 route" (requires iproute2 package) –  Olipro Nov 21 '12 at 9:37
