Open Zimbra & Ubuntu 8.04LTS - can't receive external emails

[bbarrons]

but I made the change this morning only after I tried host `hostname`
and got the message...... so put it back to the way I had it. I must have something else wrong then if it still cant resolve hostname correctly.... right?
thanks
Bill B
p.s


what do I restart to accept the change after I make it to the hostfile..... bind?

You shouldn't need to restart anything after making the hosts file change - with the qualifier that I don't know much about Ubunt.

How about the usual questions? Let's see the output of the following:

cat /etc/hosts
cat /etc/resolve.conf

dig barronsfamily.net mx
dig barronsfamily.net any

Did you also make the change to the /etc/nsswitch.conf mentioned above?

[bbarrons]

but when i had made changes and saw no difference I thought maybe something needed to be restarted. so here is my info:
bbarrons@ms2:~$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.120 ms2.barronsfamily.net ms2

bbarrons@ms2:~$ cat /etc/resolv.conf

Bill, thanks for taking the time to help me sort this out. I didnt mean to hijack this thread and maybe should have started a new one but it was right in line with what I was working on.
I am heading into work now so I wont be back to try anything until late.
again, thanks for your time

I noticed your start of authority is your local machine. Do you actually have Bind up and running properly? Silly question but I'm at a loss. Either way, I can't understand why you're not resolving from the hosts file.

Is it possible that you need to flush your DNS cache as you have to in Windows.

I'll second that, from the information you've posted I don't understand why it's not resolving correctly either.

A restart or reload of BIND should reload all your files correctly but I'd suggest the next step would be a reboot. I assume you have forwarders specified in BIND (or are you using root servers)? If you have, I'd suggest removing the additional DNS servers from your resolv.conf and just leave your local DNS server.

[bbarrons]

first, thank you both for your replies... it helps greatly to talk things thru to a conclusion.
I logged into my server at the school to run some tests. It is virtually the same setup as my home server. I ran host `hostname` and it resolved to the host name of the server so I then started to look at the files involved. In /etc/resolv.conf my school server looked like this:

bbarrons@ms1:~$ cat /etc/resolv.conf
nameserver 192.168.3.5
domain stmarysstclair.org

here is how my home server looked:

bbarrons@ms2:~$ cat /etc/resolv.conf
### BEGIN INFO
#
# Modified_by:  NetworkManager
# Process:      /usr/bin/NetworkManager
# Process_id:   6883
#
### END INFO
nameserver 192.168.1.120
nameserver 68.94.156.1
nameserver 68.94.157.1

So I did as you suggested and removed the forwarders because as you said they are already setup in bind.
It still didnt work so I then added this line to my file:

domain barronsfamily.net

so that it now looks like this:

bbarrons@ms2:~$ cat /etc/resolv.conf
nameserver 192.168.1.120
domain barronsfamily.net

worked as it should. thank you for being persistent.

Ah, that would explain it. I was assuming (always a fatal mistake) that you had that in there and just posting details of the DNS IP addresses earlier. My mistake for not spotting that. The 'domain' keyword tells the search what to append to the hostname when you do a query, that why it was failing as no domain name was added. Glad you've fixed it.

Otherwise, i think i have exhausted all my resources. I was thinking of trying another distribution. Which one can you recommend?

Thanks,

mbossmanh, have you ever knew what was the problem in your server configuration?
