Services only available on IPv6

freaky@

Regular Pleskian
Hi there,

just installed Plesk 11.0.9 on CentOS 6.3 and I noticed I can't connect to the majority of the services over IPv4. I haven't added any IPv6 addresses in Plesk yet (the machine does have a link-local address). Didn't forcefully disable it either as we do want to use it in the future.

Anyways, I can access plesk through a little SSH trickery (ssh -L 8443:<local ipv4!! address>:8443 <user>@<host>) and then connect my browser to https://localhost:8443. The odd thing is this uses IPv4 too thus.

Anyone have some tips? If this is how it's supposed to work, what's going to happen once I do enable IPv6? I really don't want to tell most, if not all, of my users that still only have IPv4 they won't be able to access the control panel until they get IPv6 which will probably be years away for most of them.

With exception of a few, most are not accessible thus. Basically anything that's only bound to :::<port> and not to 0.0.0.0:<port> (as SSH is) as well is unreachable.

TIA

If you havent added IPv6 then how are you able to tell you can't connect via IPv4? How else would you be connecting to the server?

Am trying to drive to the point that the problem might not be the IPs, but rather something with the services, blocked ports or a strict Firewall on the server ...

Am also assuming its a new plesk default installation..
