Apache Help

I am running red hat 8 and everything is great, but my httpd won't start and I am not sure why. The error log states:

[alert] (22002)Name or service not known: mod_unique_id: unable to find IPv4 address of "dhcppc9"

I have an ip address, though it is dynamically assigned . Will this cause a conflict? Any help would be appreciated. Thanks!

Try if adding the entry (w/o quotes) " dhcpp9" in your /etc/hosts works, then restart the /etc/initd./network works.

Thanks a bunch for your help!

That entry into the hosts file worked like a charm. I can now reference my site by typing "dhcppc9" in my browser. I am not sure I understand why it worked though. Why would a ip address of allow my httpd service to start?

This is also probably a stupid question, but where did "dhcppc9" come from? Does it mean the 9th pc on DHCP?.

I also put an entry for localhost in there with an ip of so I can also use localhost to access my test pages. I am psyched, things are beginning to come together for me!

Before moving to this town, I was using dialup. Given that finding packages on the net using dialup sucks bigtime, I used Windows 2000 Server. When I came to town and got on cable, I immediately jumped back to Linux, specifically RH8.0. For a long time, everything was fine. My hostname resolved to "" (numbers and hostnames changed to protect the innocent, of course).

One morning, I woke up to find my machine offline due to my cable ISP redoing something or other overnight. The machine had completely locked for some reason. I rebooted to find that my hostname had been changed from to simply... "alopa". Beats me as to why, but I noticed that I could not start httpd.

Your solution worked wonders, but I find myself wanting to know more... not just that it works, but WHY. Could you share this info?
