configure a second IP to a ethernet card

[uadm26]

Hi,

How con configure a second ip to an ethernet card?
I need only to use ifconfig?
Not in lan0 but in lan1.

[Gopi Sekar]

I believe you can use ethernet alias.

just check alias options in ifconfig (lan0:1)

Hope this helps,
Gopi

Add it to the /etc/rc.config.d/netconf file:

Example:

IP_ADDRESS[1]=192.168.164.97
SUBNET_MASK[1]=255.255.248.0
INTERFACE_NAME[1]=lan1:1
BROADCAST_ADDRESS[1]=192.168.167.255
INTERFACE_STATE[1]=up


ifconfig lan1:1 up

Using Geoff's suggestion would make the network configuration permanent and would automatically configure the new IP on a reboot. This is more than likely what you want to do.

If you're looking to test it out or for a more temporary solution, you can configure it manually via ifconfig command:

ifconfig lan1:1 inet ${ip} netmask ${nm} broadcast ${bc} up

HTH;

ok, I have done, but now I have, for example:
# traceroute alfa

traceroute: Warning: Multiple interfaces found; using 172.20.192.133 @ lan0:1
traceroute to alfa (172.20.102.123), 30 hops max, 40 byte packets
1 alfa (172.20.102.123) 0.270 ms 0.138 ms 0.135 ms


But I want to use lan1:1 :
# traceroute alfa

traceroute: Warning: Multiple interfaces found; using 172.20.102.169 @ lan1:1
traceroute to alfa (172.20.102.123), 30 hops max, 40 byte packets
1 alfa (172.20.102.123) 0.270 ms 0.138 ms 0.135 ms

How?

[Geoff Wild]

man traceroute

Specify the interface with -i

[uadm26]

ok, but traceroute -i just do it in that time not permanently, I want to change use lan0:0 to use lan1:1.

Hi

Try

route add command this may solve your problem.

route add "dest ip" "lan1:1 ip"

bye bye
