The interface to bind to, can now be specified on the command line

If you specified `y' (yes) to the configuration question during `make config' whether or not you wanted VIRTUAL HOSTING, then now you can specify the interface that you want the daemon to bind to by IP-number on the command line.

Example:

$ ircd -w 123.456.789.012

The given parameter must resolv with gethostbyname(3).

You can use the UNIX command `ifconfig -a' to find out which interfaces you have and what the IP-number of these interfaces is. For example:

$ ifconfig -a

Shows that I have four interfaces with three different the IP-numbers: 127.0.0.1, 194.109.13.237 and 192.168.1.1. If no -w command line option is given, the daemon falls back to trying to resolve the server name as specified in the M: line.
