How to bind multiple IP addresses to an SCO Nic

In SCO Unix systems, multiple IP addresses are set through the alias address of the network interface.
The procedure is as follows: (for example, the IP address of the net0 Nic is 192.168.1.2 and the mask is 255.255.255.0)

1. edit the/etc/tcp file. Vi/etc/tcp
2. find the ifconfig command line that contains the Nic device file name net0.
3. add the ifconfig command line after the command line to set another IP address (the second IP address and the third IP address…) for the NIC ......). If you set the 2nd IP addresses of the network adapter to 192.168.1.3 and the mask to 255.255.255.0, you can add the following lines: ifconfig net0 alias 192.168.1.3 netmask 255.255.255.0 broadcast 192.168.1.255 perf 24576 24576 1
4. run the reboot command to restart the machine.
5. use netstat? The rn Command lists the address information.
6. run the ping command to test network connectivity.
When configuring IP addresses of different CIDR blocks, you need to modify the broadcast addresses and add routes to access different CIDR blocks.
