/etc/resolv.conf

[coffee23]

Hi,

I was just going through emails that could not be sent and noticed one saying something about it could not find the DNS for the server (host), and that i should look at /etc/resolv.conf to determin the problem.

When i enter the above commant it comes up with the following:

/etc/resolv.conf: line 1: nameserver: command not found
/etc/resolv.conf: line 2: nameserver: command not found
/etc/resolv.conf: line 3: nameserver: command not found
/etc/resolv.conf: line 4: nameserver: command not found
/etc/resolv.conf: line 5: nameserver: command not found
/etc/resolv.conf: line 6: nameserver: command not found

i edited the file to the following:

nameserver: 00.00.000.00
nameserver: 00.00.000.00
nameserver: 00.00.000.00
nameserver: 00.00.000.00
nameserver: 00.00.000.00
nameserver: 00.00.000.00

And it came up with the following when /etc/resolf.conf was called:

/etc/resolv.conf: line 1: nameserver: command not found
/etc/resolv.conf: line 2: nameserver: command not found
/etc/resolv.conf: line 3: nameserver: command not found
/etc/resolv.conf: line 4: nameserver: command not found
/etc/resolv.conf: line 5: nameserver: command not found
/etc/resolv.conf: line 6: nameserver: command not found

Can someone please tell me why it is doing that ?

Also everytime when i log into WHM it comes up with "Hostname A Entry Missing!" so i click the "click here" button and all i get is the following:

Found your hostname to be: host 
Found your short hostname to be: host 
Found your domain name to be: 
Found your main ip to be: 00.00.000.00
If this looks correct,

notice how the "domain" is blank ??? therefore i just cross off as last time i done that and changed the hostname i got a "licence invalid" error or something like that and i just had Cpanel/WHM reinstalled but now i have got 10 users on there and i dont want to risk there accounts, if you get me.

I hope someone can help as i have spent just over a month trying to get it sorted and going through here (forum) and nothing seems to fix it.

My details are:
WHM 9.9.8
cPanel 9.9.8-R119
Fedora i686 - WHM X v3.1.0

First off you should be using an editor like pico, nano or vi. So for example nano /etc/resolv.conf.

Then resolv.conf should look something like this:
domain "server name"
domain search "server name"
nameserver "Main/Virtual IP of your server"
nameserver "IP of name server 1"
nameserver "IP of name server 2"

Restart Bind after making changes.

As far as "A" name host entry- what does /etc/hosts have in it?

Hi,

Thanks for the reply.

I use "PuTTY" to view/edit the files.

I entered what you said "should" be in the /etc/resolv.conf file and then went onto WHM and i no longer get the "A" name Host Entry Missing popup.

When i run /etc/hosts i get the following:

/etc/hosts: line 3: 00.00.000.00: command not found
/etc/hosts: line 4: 127.0.0.1: command not found

Again thanks for your help with this

When i run /etc/hosts i get the following

Post the contents of that file.

[coffee23]

# that require network functionality will fail.
# Do not remove the following line, or various programs
00.00.000.00            host host
127.0.0.1                 localhost

The above is what it comes up with

[sawbuck]

Should look something like this:

127.0.0.1 localhost
"Server IP address" "Server name" (2nd line)

[coffee23]

Hi,

Done that to look like the following and it still has not sorted out the "A entry for hostname".

127.0.0.1 localhost
"00.00.000.00" "Server name"

I dont get the annoying "popup" anymore (thanks) but if i goto DNS then "Add an A Entry for your Hostname" it still shows the following:

Found your hostname to be: host 
Found your short hostname to be: host 
Found your domain name to be: 
Found your main ip to be: 00.00.000.00 
If this looks correct,

After changing /etc/hosts you need to reboot your server for changes to take effect. If that doesn't solve your problem then I would say you have 2 choices. Either go step by step thru your setup in WHM and confirm by checking the corresponding files in putty or just hire someone to sort it for you. Chirpy on this forum can make short work of resolving your problem.

EDIT: I believe I was wrong. Reboot after seems to make things go more smoothly at least.

At any rate, coffee, here's an example hosts file for you. Use it as an example, and substitute the name of your server and your own main ip

127.0.0.1 localhost
123.345.456.678 coffee.coffeedomainname.com coffee

So by this example...
your hostname to be: coffee.coffeedomainname.com
your short hostname to be: coffee
your domain name to be: coffeedomainname.com
your main ip to be: 123.345.456.678

Hi,

Done that but it still shows the same as before however the /etc/hosts file now displays the updated.

Thanks for all your help trying to get it sorted.

I think i will get someone to take a look into it (see some peeps under the "ads" forum).

You dont have to reboot the server!
a simple killall -HUP named should solve this.

Dont reboot the server before changes...
This is linux, not windows!

Also...
Dont use the
127.0.0.1 localhost
line.

Read the reason here:
what should /etc/resolv.conf look like?
