redundancy in domain or hostname ?

[Walter Jansen]

The router connected to my server reports DNS inquiries like
"myserver.example.com.example.com" which obviously leads nowhere

 

The server is in a SOHO situation connected to a router which is connected
to DSL; the server runs 6.3 Release and will serve as mailserver for the few
in-house employees  and as a webserver. The domain "example.com" is
registered with Dyndns.org who also run the "Custom DNS service".  The DNS
entries were checked with Dyndns.org staff and found in accordance with the
purpose.  

During installation  of the server, the hostname "myserver.example.com" and
the domain name "example.com" were entered in the appropiate Sysinstall
dialog

. 

/etc/hosts shows:

 

::1                     localhost.example.com localhost

127.0.0.1               localhost.example.com localhost

192.168.1.13            myserver.example.com myserver

192.168.1.13            myserver.example.com.

 

192.168.1.13 is allocated to the server by the DHCP of the router; this IP
address is fixed though!!

 

 

Table /etc/resolv.com reads:

 

domain  example.com

nameserver      192.168.1.1  (my router's IP address

 

 

I postponed installation of Postfix and Apache as I feel that host- and
domainname should be configured correctly to prevent accumulating trouble.

 

Remarks a most appreciated.
