An office workstation, real.nook.net, is on 216.47.28.76. It
uses interface eth0.
I created a virtual interface for it as eth0:0, on 216.47.28.90
and called it virtue.nook.net.
Here is my routing table:
216.47.28.0 0.0.0.0 255.255.255.0 u 0 0 21 eth0:0
216.47.28.0 0.0.0.0 255.255.255.0 u 0 0 3 eth0
127.0.0.0 0.0.0.0 255.0.0.0 u 0 0 2 lo
0.0.0.0 216.47.28.1 0.0.0.0 UG 0 0 7 eth0
It answers to ping on both interfaces, but there are some
anomalies *within* the network:
1. If I telnet from this box to another box, the other box
registers the login as "virtue", rather than "real".
2. DNS services and httpd are now deaf on the 216.47.28.76
interface (real), even though it anwers to pings there.
3. I configured a virtual server for Apache on the virtual
interface; that works fine, but the port on "real" is deaf.
4. NFS to/from other boxes died until I enabled "virtue" rather
than "real" the client in the /etc/exports of other machines.
OK, what am I missing here? Is there a way to prioritize
these interfaces so the "real" one is used for all services
and the virtual one for the virtual web server on "virtue"?
