Routing table

Currently, i have 2 NIC for 2 different segments, segment 1 and segment 2. segment 1 connect to switch 1 and segment 2 connect to siwtch 2. Therefore , i want to know how to configure that all my server can talk each other. segment 1 can talk to segment 2. Purpose of segment 1 is production and segment 2 is for backup purpose. thanks.

/etc/rc.config.d/netconf
set up ip, mask, and default router for interface [0] and [1],

add aliases for the nic cards in /etc/hosts.

check /etc/rc.config.d/namesvrs for any name configurations, (yp, etc)
good luck

Hiya.

Assuming seg1 is 192.168.1.x and seg2 is 192.168.2.x, switch IP is ...1 and machine IP is ...100

configure lan0 to be 192.168.1.100
configure lan1 to be 192.168.2.100

configure default route to be switch 1

root@myserver> route add default netmask 255.255.255.0 192.168.1.1

configure backup route to use switch 2

root@myserver> route add net 192.168.2.0 netmask 255.255.255.0 192.168.2.1

Edit the /etc/rc.config.d/netconf file to reflect above changes.

I think that's all.

Cheers!
James

Sounds more like you want the server with 2 nic's to be a router/gateway between the networks.

All you need to do is have ip_forwarding enabled on the server with 2 nics.
ndd -set /dev/ip ip_forarding 1

On your clients, they will have to either know this machine then as a default router, or make static routes to each network using this host as the gateway.
