Problems with IPv6 support

Post by deki »

Hi!

I'm trying to run UnrealIRCd 3.2.4 on FreeBSD 6.0 with IPv6 support.
But after starting the IRCd there are no open ports (even nmap can't detect any)
and there is nothing unusual in the log files.
There is also no firewall running.

After compiling UnrealIRCd without IPv6 support, everything works fine.
But I need IPv6 support. Always after compiling with IPv6 support it doesn't wor
k any longer.

Has anybody an idea?

Hi,

Try "sysctl -w net.inet6.ip6.v6only = 0" as root

or add

net.inet6.ip6.v6only=0

to /etc/sysctl.conf and reboot

Then restart the irc daemon and see how it goes.

There are potential security issues with this setting
(hence why it's disabled in Open/Net/FreeBSD by default).

If it works this probably belongs in the Unreal FAQ somewhere.

adrian.
