Re: binding to particular IP on multi-ip machine failed with 2.2.0

Hi,

yes, I can confirm that it works with all 2.0.x including 2.0.9, but does not with 2.2.x

FreeBSD specific is that you specify IP address aliases with netmask 255.255.255.255.

For example:
# ifconfig
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=3<RXCSUM,TXCSUM>
        inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
        inet 10.0.0.2 netmask 0xffffffff broadcast 10.0.0.2
        inet 10.0.0.3 netmask 0xffffffff broadcast 10.0.0.3
        inet 10.0.0.4 netmask 0xffffffff broadcast 10.0.0.4

This worked in 2.0.9 and we are still using pretty much the same calls
to PWLib. How come this broke ?

Since we don't do anything special for FreeBSD, is this broken on other
Unix versions as well ?

Is it FreeBSD system? I noticed, that 2.2 has problems

I was just trying to set gnugk 2.2.0 on machine with multiple IP
addresses (for multi-gk setup) to bind to particular IP address.
However, all possible configurations always ended up with gnugk
listening to machine's default Ip address AND localhost address.

Example:
machine default address: 10.0.0.1
aliases:                 10.0.0.2 and 10.0.0.3

we want particular gnugk instance to listen to 10.0.0.2

config is like this:

[Gatekeeper::Main]
Fourtytwo=42
Name=gnugk
StatusPort=7000
Home=10.0.0.2
NetworkInterfaces=10.0.0.2/32
UseBroadcastListener=0

it gives following debug at startup:
2004/12/02 22:21:27.587 2 singleton.cxx(28) Create instance: Toolkit(1)
2004/12/02 22:21:27.587 5 Toolkit.cxx(592) Try name /tmp/gnugk.ini-2052
2004/12/02 22:21:27.589 4 Toolkit.cxx(113)

InterfaceTable:> 10.0.0.1 (sis0)

127.0.0.1 (lo0)

2004/12/02 22:21:27.591 2 Toolkit.cxx(83) Network=10.0.0.0/255.255.255.0, IP=10.0.0.1
2004/12/02 22:21:27.591 2 Toolkit.cxx(83) Network=10.0.0.1/255.255.255.255, IP=10.0.0.1
2004/12/02 22:21:27.591 2 Toolkit.cxx(83) Network=10.0.0.3/255.255.255.255, IP=10.0.0.1


.... and so on for all interfaces on machine, then localhost....

2004/12/02 22:21:27.591 2 Toolkit.cxx(83) Network=127.0.0.1/255.255.255.255, IP=127.0.0.1

2004/12/02 22:21:27.592 2 Toolkit.cxx(84) Default IP=10.0.0.1
2004/12/02 22:21:27.594 2 Toolkit.cxx(83) Network=0.0.0.0/0.0.0.0, IP=10.0.0.2
2004/12/02 22:21:27.594 2 Toolkit.cxx(84) Default IP=10.0.0.2
2004/12/02 22:21:27.591 2 Toolkit.cxx(83) Network=63.208.156.113/255.255.255.255, IP


so it kind of detects Home address, but also detects all other
addresses on machine and decides to listen to main and localhost:

Anyone has idea how to make it listen to "home" only? Needless to

say,> that till 2.0.9 it worked as expected
