configuration error DNS
I have Red Hat linux 9. I am running a APACHE wbserver on the same machine as I am running my DNS server. But when i try to connect to my website, i get a message like " can not connect to host". I can surf for all pages on the net except my own. And everybody else can connect to my website. I have a USrobotics router/firewall, but i don't think that the problem relates to it.

I'd start by making sure your Apache is listening where you think it is. 'netstat -na' would get you started... look for a port 80 listener on the IP wherey ou expect you web server. If no listerner, check apache config. If you have a listener, make sure a "dig www.whatever.com" from your command line returns the IP its listening on. If that's wrong, you have a DNS config error.

Can you view your webpages by using http://localhost from the machine the server is on? OR Can you view your webpages using http://your-machine-name from inside your network? If everyone else can connect to your website, it's neither a dns or router issue. You might substitute http://127.0.0.1 for localhost, if neither works try installing a loopback adapter.

Sorry for replying so late, but i had a accident (broke a leg)

This is what i found after typing
[root@server root]# netstat -na

I don't see my ip (192.168.1.1) with a port 80 bound to it. So this means that the apache config is wrong, but what and where?!!!?!?
I can see my page when i type in http://localhost

This line:

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

Means that apache is listening on all interfaces port 80. So whether you're connecting to 127.0.0.1 or 192.168.1.1 or your public IP, you will always connect to apache.

configuration error DNS
So what could be the problem? I am also running a ftpserver on the same machine. And when i try to connect to the ftp server from the same machine, i get this error message:" could not connect to server. Temporary error in resolving the name."
This is highly peculiar, because my resolv.conf reads:

domain mydomain.com
search mydomain.com
nameserver 192.168.1.1 ' this my server adress

You need to follow freemans-web's advice and follow those diagnostic tests. Then let us know how things went.

You don't need to install a loopback device. You already have one cause localhost works and most undoubtedly uses 127.0.0.1.

I think I know what may be wrong. I want you to test something for me. Since I don't know what your IP is, go to the following URL and click the link and tell me if you get exactly the same response as when you connect to your own domain.

****

IF IP WORKS...

Then you need to do 1 of 2 things. Either configure BIND to use "Views" so that it returns the LAN IP for local requests, and the public IP for public requests.... or.... add the following line to your "/etc/hosts" file:

192.168.1.1 www.mydomain.com mydomain.com

IF IP DOESN'T...

This has got to be either a resolv.conf error or a DNS error, but since the resolv.conf file looks fine, and your site IS accessible from the internet, I really don't see how either one could be wrong.

er. I think I got the IP WORKS/DOESN'T instructions switched up. But glad you got it working. I'm removing the link from my previous post now so that I don't have to keep the file there.
