2 IPs and domains
 

Stupid newbie question here

1) I just recently set up RH9.
2) I have an external router/firewall that handles one-to-one NAT on my external IP addresses (i.e. EXTERNALIP1 --> 192.168.254.10 and EXTERNALIP2 --> 192.168.254.11).
3) Both external IPs are registered domain names that I own (domainname.com)
4) OK - here's the question... both of the mentioned internal IPs need to point to my linux machine. I have 1 configured so far and here is the ifconfig for my single NIC:

eth0 Link encap:Ethernet HWaddr 00:04:5A:64:62:51
inet addr:192.168.254.10 Bcast:192.168.254.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:13212 errors:0 dropped:0 overruns:0 frame:0
TX packets:10375 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:12378958 (11.8 Mb) TX bytes:2735929 (2.6 Mb)
Interrupt:11 Base address:0x4000

5) not sure if this helps, but here is my IP routing table.

Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.254.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.254.254 0.0.0.0 UG 0 0 0 eth0

6) So (A) how do I set up 192.168.254.11 on the same NIC??
7) And (B) I get messages on FQDN's not being configured: i.e when I start Apache:

Starting httpd: httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

Thanks in advance!

Mapping the domain names to ip addresses in /etc/host might solve the fqdn problem

You'll need to configure an ethernet device alias. Here's a link to the RH9 manual page that describes how to do that :

http://www.redhat.com/docs/manuals/l...k-aliases.html

For the Apache problem you might need to set up the ServerName directive in your httpd.conf file. If you plan to host 2 web sites from the same machine you'll need to be using VirtualHost directives.
