[gentoo-user] One host, two NIC's...
Hey all. Linux question - I have this nice big dual Xeon server, with two NIC's. Where, how, when, why, can I configure this beast, not as a router, but just as a host with two ways to get in. eth0 is 192.168.0.39 eth1 is 192.168.1.139 I would like to be able to associate both NIC's to the same hostname, 'foo' - how is this accomplished? Thanks much! -- gentoo-user@gentoo.org mailing list

Hi Jeff, I think you should try to adjust your /etc/hosts and put in it :192.168.0.39 192.168.1.139 fooYou may also need to adjust your routes : [EMAIL PROTECTED] add default gw 192.168.0.X 192.168.0.39[EMAIL PROTECTED] add default gw 192.168.1.X 192.168.1.139 On 2/5/06, Jeff <[EMAIL PROTECTED]> wrote: Hey all.

Thanks much! cd /etc/init.d/ ln -sf net.lo net.eth1 rc-update add net.eth1 default vi /etc/conf.d/net config_eth0=( "192.168.0.39/24 brd 192.168.0.255" ) config_eth1=( "192.168.1.39/24 brd 192.168.1.255" ) routes_eth0=( "default via 192.168.0.1" ) If you want more than one gw you'll need to turn on advanced routing in the kernel and then add a routes_eth1 line as well. In DNS I'd do something like this server IN A 192.168.0.39 server IN A 192.168.1.39 eth0.server IN A 192.168.0.39 eth1.server IN A 192.168.1.39 And map reverse DNS to the eth0 and eth1 names as well. It'll make troubleshooting easier if you have issues later on. kashani -- gentoo-user@gentoo.org mailing list
