Hey Folks,
I am running DNS on a DEC200 operating on Digital Unix 3.2g.
Question:
Why is it that when I set an IP Alias Address onto a given interface that
the last Alias IP Address with a Valid DNS or "/etc/host" entry is used by
the machine to identify itself to the rest of the NET? It seems to reason
that the primary IP Address of the machine should be used for
identification. Right?
For instance:
The machine has been configured with primary IP Address --> 10.10.10.1
1. I issue the command --> # netsat -I tu0 ...with results....
Name Mtu Network Address Ipkts Ierrs
Opkts Oerrs Coll
tu0 1500 <Link> 08:00:2b:xx:xx:xx 11593 0
8093 0 3
tu0 1500 10.10.10 ns 11593
0 8093 0 3
2. I set an IP address Alias using --> ifconfig tu0 alias 10.10.10.2
3. I then re-issue the command --> # netsat -I tu0 ...with results....
Name Mtu Network Address Ipkts Ierrs Opkts
Oerrs Coll
tu0 1500 <Link> 08:00:2b:xx:xx:xx 11593 0
8093 0 3
tu0 1500 10.10.10 ns.otherdomain.com 11593 0 8093
0 3
NOTE: "ns" equates to 10.10.10.1
and ....
"ns.otherdomain.com" equates to 10.10.10.2
Any ideas?
Regards,
