Virtual IP/IP Aliasing...
Posted on 2000-03-16
Can I assign 2 IP addresses to one interface? We are moving some systems around, and one box is now taking on the responsibility of what was previously 2 boxes. I want all the PCs on the network trying to hit the old IP address to hit the new box, although the new box has a new IP... that sounds confusing. Here's an example:
Machine A = 192.168.1.1
Machine B = 192.168.1.40
Machine B is now out of service. Machine A has taken over it's duties. People hit this machine by IP address. In the interim, we'd like anyone going to 1.1 OR 1.40 to hit Machine A, 192.168.1.1
Is this possible? Under linuxconf (Using RedHat 6.1 btw) I saw a section for IP Aliasing, and I added the new address to it, but I cannot ping/telnet to/etc the new 'aliased' address. Any ideas?
