2NICs 2 IP's 1 network
Got a Dual 1GB NIC server running salckware 10.1
this is a replacement server for a couple of existing machines and as such I'd like it to keep both the existing IP's i.e. old Server 1 [192.168.1.10 ] old server 2 [192.168.1.20 ] becomes newserver : nic 1 [192.168.1.10] - done and working : nic 2 [192.168.1.20] - I'm using webmin to configre stuff though can hand edit anything that is needed with one NIC enabled :- routing seems to work and I can get to the internet :- Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface localnet * 255.255.255.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default ipcop 0.0.0.0 UG 1 0 0 eth0 When I enable the 2nd NIC Destination Gateway Genmask Flags Metric Ref Use Iface localnet * 255.255.255.0 U 0 0 0 eth0 localnet * 255.255.255.0 U 0 0 0 eth1 loopback * 255.0.0.0 U 0 0 0 lo default ipcop 0.0.0.0 UG 1 0 0 eth0 then routing does not work and I cannot see the internet :( how can I make both NIC's work and respond ? as this will give me [theretically x2 bandwith to server also] |
OK -- have got things running
ifconfig eth1 192.168.2.10 netmask 255.255.255.0 broadcast 192.168.2.255 mtu 1500 up route add -host 192.168.1.20 dev eth1 route del -net 192.168.1.0 netmask 255.255.255.0 dev eth1 route add -host 255.255.255.255 dev eth0 seems to do the trick and I can connect on either IP number now. now to get the services running that I need. error #1 - don't confuse your Broadcast number with your gateway |
