Greetings! I've been struggling for a few days now with something that gives me a headache 'cause I'm not really an iproute expert, nor even an advanced user. I've browsed through the archives, HOWTO's and such but didn't pick up anything particularily useful to help me with my little problem. I have two network cards installed on a single RedHat8 Linux (2.4.18-14) box, each interface has it's own dedicated IP address, both have the same mask and gateway. Now, what I'm trying to do is dedicate eth1 to icecast (a stream server) only, so that any other outgoing/incoming traffic (HTTP, FTP, SSH, ICMP etc) would use eth0. I managed to set up my firewall (with fwbuilder, iptables) so that only icecast answers on eth1 and the rest of the allowed services on eth0. But clearly whether you connect to http on eth0 or icecast on eth1, there is traffic only on eth1 (at least when you look at "netstat -i" or Tx_Bytes & Rx_Bytes in /proc/net/PRO_LAN_Adapters/eth*.info). That's probably because "ip route ls" shows that Red Hat has set eth1 as my default gw. So.. I guess what I'm asking is what would the right "ip" commands be that'd allow me to set up my routes in such a way that would make all this possible? .. and moreover, how do I get Red Hat scripts not to mess with those settings.. ;-) Thanks in advance! Excuse me if my explanation is not very clear, too much monitor tan for today.
Jesper.... (Sorry for brief reply...work, work, work...) Try something like this # echo 5 icecast >> /etc/iproute2/rt_tables # ip rule add from $ETH1_IP table icecast # ip route add default via $ETH1_GW table icecast Does that make sense?
