Hi,
I am presently setting up a server for a gamin event I am planning to run. I
have a Linux box running Debian and a 2.2.20 custom kernel. I have IP alias
compiled in and can create the aliased interfaces. My ifconfig output as
shown below proves this :
eth0 Link encap:Ethernet HWaddr 00:40:95:30:73:83

The game client has however been unable to connect to the server, using
tcpdump I can see the request from the server going to the broadcast address
as shown below.
11:53:01.315928 kryten.1480 > 255.255.255.255.27015: udp 16
The server however, never replies. When pinging the broadcast address, the
ip address of the interface replies as shown below but none of the aliased
addresses reply to the broadcast ping. Is this normal behaviour? Should
aliased addresss reply to pings?
64 bytes from 192.168.0.101: icmp_seq=2 ttl=255 time=0.0 ms
One other observation that may or may not effect this is that there is no
/proc/net/aliases file. Aliases is compiled into the kernel rather than as a
module.
Thanks for any help
