Strange Apache Problem

[becatlibra]

Okay - I've tried my local LUG and haven't found the answer - I've look on the internet all morning and nothing seems to fit my specific issue.

Here goes - I have a server running FC6 (due to a software requirement) that has a mailserver package installed.

I wanted to host another server on this same machine. Now the mailserver doesn't use apache or anything but I was told I can set it to listen to it's own IP so here is where I am at.

Using Fedora's 'tools' I setup another IP on the same nic so now ifconfig shows:

[root@mercury /]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:13:72:0B7:5A

So the mailserver is listening on the correct IP. However, when I try to start httpd I get this error:
[root@mercury /]# httpd
(9Address already in use: make_sock: could not bind to address 192.168.1.205:80
no listening sockets available, shutting down
Unable to open logs
[root@mercury /]#


I had to modify the /etc/httpd/conf/httpd.conf file so the listen specified 192.168.1.205:80 (the fedora utility creates a conf file in /etc/httpd/conf.d/) -- without that it kept saying something about 0.0.0.0:80 which was screwy because the /etc/httpd/conf.d/system-config-httpd.conf specified the correct IP.

Anyway - does ANYONE have ANY ideas?

nmap shows that 192.168.1.200 is open and listening and 192.168.1.205 isn't

Please help if you can

Thanks

Well - I went into the /etc/httpd/conf/httpd.conf file and removed the line I changed. Originally it was Listen *:80, which gave an error about 0.0.0.0:80 (even though the Fedora System Generated file /etc/httpd/conf.d/system-config-httpd.conf specified Listen 192.168.1.205:80) so I changed it to Listen 192.168.1.208:80 in that file (httpd.conf)

I just commented that out and it seems to have started fine and the test page is up. My only question is WHY?

Guessing got it working but I really want to understand what the problem was. Is it that the IP is mentioned in two files so it was trying to 'double allocate'??
