Hello
let me cut to the chase and get on the subject...
I'm running FreeBSD 4.3-STABLE (used to 4.3-RELEASE)
I already had ip 66.92.98.145
su-2.05# host 66.92.98.145
145.98.92.66.IN-ADDR.ARPA domain name pointer oXyeTb.com
su-2.05#
and I wanted to bind ip 66.92.98.151
su-2.05# host 66.92.98.151
151.98.92.66.IN-ADDR.ARPA domain name pointer MbI.PyCCKuE.com
su-2.05#
I bind another ip (2nd) to my existing interface as an alias using command
ifconfig fxp0 alias 66.92.98.151 netmask 255.255.255.255
su-2.05# uname -a

as you can see I have 2 interfaces fxp0 used for external (internet) ips and
dc0 for internal (intranet) network
let me show you my routing table without dc0 interface
su-2.05# netstat -rn | grep -v dc0

... now the problem that i'm having for some reason whenever i'm trying to
IRC w/ my 2nd ip and for some reason it rolls over to first ip
i've tryed following clients
su-2.05# BitchX -v
BitchX - Based on EPIC Software Labs epic ircII (1998).
Version (BitchX-1.0c18) -- Date (20010108).
Process [9357]
BitchX version BitchX-1.0c18 (20010108)
su-2.05#
BitchX with -H
ircII with -h
su-2.05# irc --version
ircII version 4.4Z (20000831)
su-2.05#
and eggdrop 1.6.6
su-2.05# grep "set my" /home/alexus/eggdrop/bot.conf
set my-hostname "MbI.PyCCKuE.com"
set my-ip "66.92.98.151"
su-2.05#
I also copy my binary to another box to see maybe something wrong with
client(s) .. nope they all workin fine
I was able to irc using 2nd ip on another box using same software
...
to make sure that ip is working itself
i'm able to telnet/ssh/www/ftp to that 2nd ip so it works.. although i'm not
quite sure if its rolls over to first ip or not..
i'd assume it is.. but i dont know for sure
