Hello all,

My server name is centos.linux.local. The httpd service is running. I can access the webserver via IP address on the browser 10.0.0.25. But when I type localhost or linux.local or centos.linux.local I get server not found error. Does anyone have any suggestion what I am missing here?

The content of the /etc/hosts file;
[root@centos /]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.25 linux.local

The DNS and named is running also.

Where did you type that text? on what host, using what app .....?

When I open a browser firefox or IE. On the browser url. When I type www.linux.local or linux.local

on the same host or on another one?

The Linux OS with Apache web server is on a laptop. I am trying to access it from another computer within the same network LAN. Is there any other configurations needed to be done on the router? In my router there is a section for Tertiary DNS. There is another section in my router called port forwarding/port triggering and services to select such as FTP, HTTP, ICUII, IP Phone, Net Meeting, News etc. Do I have to configure this option? Maybe I am off and I need to do something on the Linux box? Thanks

Ok.... sounds like you need to set up that other computer (the one that you are using FF or IE on... for sure IE you are not using on gnu/linux) to use the linux server as its DNS server. Plus enable access to dns service on the linux server.

What is the output (on the guindous computer) of this?

yes, it looks like you need to configure the DNS service. (just a remark: localhost will never work, do not try that)

How do you do it? I mean what and where do I configure the server side? Do I need to do something on the client computer also? I want simply to be able to connect to the local LAN Apache web server using domain name instead of typing IP address at the browser url yet I want to be able to have my regular Internet access also. Is it doable? Where to configure DNS service? On the Linux box?

the most simple solution would be to edit your hosts file: http://helpdeskgeek.com/windows-7/windows-7-hosts-file/
add the following line at the end:
<ip of your linux server> <name of that host>

I guess you need to set up your linux server as the DNS server of the guindous client (remember to open access to named on the firewall of the linux server). That should take care of name resolution on the guindous box.

I'm assuming your Linux box's host name is linux and the domain is local (from your hosts file entry).

If so, you've got a number of configuration errors:

your search line in resolv.conf should be:
search local

Your Windows machine's nameservers should be pointing to your Linux box. It appears that you are using DHCP on your router/gateway so you'll have to figure out how to configure that.

Your reverse zone should be:
$ORIGIN 0.0.10.in-addr.arpa.
not
$ORIGIN 25.0.0.in-addr.arpa.
...and also check your named.conf file for the proper matching entry.

In your 'ifcfg-eth0' file, the DOMAIN should be 'local'

Oh, and host names in the forward DNS file should be like 'centos.local'.
That should be a good start....

Thank you all.
