[SOLVED] ERROR LOG: Name or service not known

[emcampos]

Sir;


If the error below appears, does it mean that I have configured my Zimbra wrong or that it's lacking some support for the said service?

How do I fix it?

( tail -f /var/log/zimbra.log )

You have something wrong with your system configuration so please post

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes

hosts, resolv.conf and DIG tests are okay now.

but what could be reason for this "hostname company1.com verification failed: Name or service not known"?

Please post the information I asked for so that we can validate it for you

[emcampos]

only this failed;

admin@mail2:~$ host `hostname`
Host mail2 not found: 3(NXDOMAIN)

i tried adding an entry in the Reverse Lookup on the local DNS but same thing.

where am i wrong here?

this is the whole test result;

admin@mail2:~$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.253 mail2.mydomain.net mail2 mail2.mydomain.net

Add to the top of /etc/resolv.conf

search mydomain.net

And change your /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.1.253 mail2.mydomain.net mail2

Your DNS results are not correct. You should do a dig on the domain name not the FQDN of your server, like this:

dig mydomain.net mx
dig mydomain.net any

[uxbod]

Doh! Missed that again Phoenix
