[Server configuration] ubuntu8.10 server sets multiple IP addresses

Two methods:
1> Modify/etc/Network/interface
The original interface file is as follows:

1. Auto Lo
2. Iface lo Inet loopback
4. Auto eth0
5. Iface eth0 Inet static
6. Address 192.168.7.72
7. Netmask 255.255.255.0

Now you need to add an IP address 192.168.53.75 with a mask of 255.255.255.128. In the above file, add the following content:

1. 1. Auto eth0: 0
2. 2. iface eth0: 0 Inet static
3. 3. Address 192.168.53.75
4. 4. netmask 255.255.255.255.128

You can add eth0: 1 eth0: 2 ......

2> in the above method, after the ubuntu8.10server is restarted, the 2nd IP addresses cannot be added.
You can also use the command line: ifconfig eth0: 0 192.168.53.75 netmask implements 255.255.255.128 up
Add/etc/rc. Local
