Configuring eggdrop with IPv6

IPv6 support

This document provides information about IPv6 support which is eggdrop feature since version 1.8.0.

About

Eggdrop can be compiled with IPv6 support. To make use of this, you need an IPv6-enabled OS and IPv6 connectivity. Every possible type of TCP connection can be established over IPv6 now, which includes IRC connections, DCC connections, file transfer, botnet connections, Tcl script connections initiated with the listen/connect commands, telnet and ident lookups.

Installation

./configure and install as usual, the configure script will detect if your system supports IPv6 and will enable it automatically. You can override this behavior and manually enable or disable IPv6 with ./configure --enable-ipv6 or ./configure --disable-ipv6. Older operating systems may have limited or no support for IPv6. Linux 2.4 & 2.6, FreeBSD, NetBSD, OpenBSD and Mac OS X all have full IPv6 support. MS Windows has proper support beginning with Windows Vista. XP's IPv6 stack has some limitations and needs to be manually installed and enabled. Cygwin includes IPv6 only since version 1.7. Unofficial patches are available for 1.5.x.

Usage

You can use IPv6 addresses wherever you could specify IPv4 ones. IPs and hostnames are interchangeable everywhere. For certain settings and commands, you can enclose IPv6 addresses in square brackets to prevent the colon character (:) from being interpreted as a port separator. These are documented in the help files and the html documentation, so you can consult them when in doubt.

CTCP CHAT/CHAT4/CHAT6

When a user sends a CTCP chat request, the request is passed to the bot via the IRC server, hiding the user’s IP. Since Eggdrop is unable to ‘see’ the type IP of the user is using (IPv4 or IPv6), it is thus unable to determine whether it should send back an IPv4 or an IPv6 address for the user to connect to. To work around this problem, the CHAT4 and CHAT6 commands were added to Eggdrop to force it to present an IPv4 or IPv6 address for use with a DCC connection, respectively. Otherwise, the traditional CHAT command will likely result in the Eggdrop presenting an IPv4 address to the user. So in short, if you’re on an IPv6 address and want to use CTCP CHAT to initiate a DCC session for the partyline, use CHAT6, not CHAT as the CTCP argument.

Settings

There are four new IPv6 related config variables:

vhost4

set this to use a specific vhost with IPv4 connections. Can contain either an IP address or a hostname.

vhost6

set this to use a specific vhost with IPv6 connections. Can contain either an IPv6 address or a hostname.

prefer-ipv6

when a connection can be established through both IPv4 and IPv6. You can set this to 1 to prefer IPv6 or to 0 to prefer IPv4.

listen-addr

the address to bind to for listening (telnet/bot ports, /ctcp chat, file send, script listen, etc.). Can be either an IPv4/IPv6 IP or a hostname. If a hostname resolves to both type of addresses, prefer-ipv6 will determine which to be used.

Other affected variables:

my-ip and my-hostname are removed now. Their function is split between vhost4 and listen-addr.

nat-ip works with IPv4 as it used to. It has no meaning for IPv6 and is not queried for IPv6 connections.

 

Edit  /home/sisrv/MyBot/eggdrop.conf and set the IPv6 hostname to use:

set vhost6 "sisrvrocks.net"

To make sure IPv6 is the preferred protocol:

set prefer-ipv6 1

Now, add irc servers with IPv6 support and you're good to go!
