Package: ircii

Severity: important


Hi Darren,

I noticed recently that I can not initiate DCC SEND and DCC CHAT from
ircII on my home computer. Epic4 works fine. After some investigation
I found the reason:

I use iptables-base firewall and ip-conntrack-irc kernel module (from
kernel-patch-irc package). The computer works as a router between the
home network and the cable modem, and therefore it has two IP
addresses - 192.168.2.1 (eth0) and 62.252.23.99 (eth1). Unlike epic4,
ircII always uses 192.168.2.1 in DCC SEND and CHAT commands.
Obviously, ip-conntrack-irc module gets confused, reports this as
forged DCC command, and refuses to accept the reverse connection. 

I have not made the patch yet, but I think the problem is in the
connect_to_server_direct() functon inside server.c. When it figures
out the local IP address of a server connection, it should use
the address reported by getsockname() rather than rely on gethostname(). 

When I rebuilt ircII with --disable-ipv6, the problem has gone, so
must be inside that #ifdef INET6 block (lines 894-910 of server.c).

Regards,
Dima.

The code in question seems to have been rewritten
for version 20020912, so I guess this bug should
be fixed since version 20020912-1. (Or there is
a new unrelated bug). Thus closing this one.
