Installation - DNS error

[mveerdon]

I'm preforming a reinstall of Scallix, but now I get suprised by a DNS/FQDN error.

can somebody help?

My etc/hosts file:
83.96.151.195 vandeveerdonk.net, hostedby.vpshoster.com
127.0.0.1 localhost

installation log :

Your /etc/hosts must contain the name assigned to your machine. To find this, do a

hostname -s
hostname -f

Both these must be listed next to the IP address in /etc/hosts. It is best if there are no other hostnames attached to the IP. In addition, your DNS server must return the same information for both forward (A record) and reverse (PTR record) lookups.

you main like this?

1.2.3.4 name name.domain.com

[Valerion]

Normally I do it the other way around

1.2.3.4 name.domain.com name

hello there

i just have problems to get scalix working again

first i had some problems with my fedora 7, i did a mistake while trying some things, after this mistakes i did an upgrade to fedora 9, everything except Scalix is working fine, before upgrading to f9 and the mistakes everything including scalix works fine

so i decided to upgrade scalix from 11.4.1 to 11.4.2 but get the network error as described by mveerdon

the commands as described by Valerion result exactly the names they should result and the hosts file contains both names with the ip-adress

so what am i doing wrong...please help

greets luke

What exactly is in your hosts file?

[Luke512]

Code: Select all

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
#192.168.1.11   hostname.domainname.home hostname


i also tried without # before the ip adress but get the same result...
as i told in my previous message before my mistake everything works fine without the line 192.168.1.11 ......

[schmoe90]

And:

Code: Select all

# hostname -a
# hostname -f
# hostname -i


[Luke512]

hostname -a = no result/blank
hostname -f = hostname.domainname.home
hostname -i = 192.168.1.11

[schmoe90]

The hosts file should be:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.1.11 hostname.domainname.home

I'd expect that to work.

hello schmoe90

i tried that way but no success

what me gets wondering that the log-file (in this case messages) is empty...when i restart the network service there should be a message in the file...but nothing

i think i have to make a fresh install of the os on my server, because theres something else wrong...maybe or not.. i don't know

[kool4caats]

I found that the problem was just that the hostname provided by the command 'hostname' was uppercase, and in my hosts file it was lowercase.

I did:

#hostname <<hostname in lowercase>>

and the system check worked!

[Luke512]

still no success...

i also tried installing scalix on a fresh centos 5.2 and get the same error

PS: i even tried so set hostname in lower and uppercase but no success... here is what i get at the moment

Code: Select all

hostname               hostname
hostname -f            hostname.domainname.home
hostname -a           hostname localhost.localdomain localhost

Check with ifconfig that you're using the IP address that's in /etc/hosts?

I can't make this _not_ work
