| Summary | 0002741: listen *:port on IPv6 enabled UnrealIRCd only listens on INET6 | ||||
| Description | When UnrealIRCd is compiled with IPv6, adding a "listen *:6667;" to unrealircd.conf will ONLY listen on INET6 Looking for a way to listen on IPv4 aswell without having to specify each address. | ||||

you get connection refused if telnetting to your ipv4 addr on that port? Most likely freebsd specific then I think... maybe you need to tweak a sysctl ? (I know there's one for ipv4 to ipv6 mapping [eh, or reverse], but don't know if that's the one...). |
|

If I try telnetting I get connection refused. I attempted this with Linux, and I did not get the same problem. It seems its just a FreeBSD specific issue. Perhaps if anyone knew of a fix for this? |

For general interest purposes, using the same config files (listen *:6667;) : FreeBSD: # telnet 127.0.0.1 6667 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host # telnet ::1 6667 Trying ::1... Connected to ::1 Escape character is '^]'. :irc.xxx.xxx NOTICE AUTH :*** Found your hostname Linux: # telnet 127.0.0.1 6667 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. :irc.xxx.xxx NOTICE AUTH :*** Found your hostname # telnet ::1 6667 Connected to ::1. Escape character is '^]'. :irc.xxx.xxx NOTICE AUTH :*** Found your hostname Same arguements passed to ./configure and same unrealircd.conf so it seems its definately a freebsd related issue. Ideas please? |

I think I've found a solution: When binding to an IPv6 wildcard socket FreeBSD doesn't accept IPv4 connections on that port. This can be changed by sudo sysctl -w net.inet6.ip6.v6only=0 or add net.inet6.ip6.v6only=0 to /etc/sysctl.conf and reboot. |

Yes this was definately the solution. All is now working as it should be. :) |

|
Thanks montarotech, that's probably something we should document/mention somewhere then ;). |
|
|
:) Glad i could help |
