Fedora 16: intranet DNS problem: FQDN don't resolve

[Sagari]

Hello,

Operating system: Fedora 16 x86_64

I am trying to understand the problems of the following. We have a local domain in our intranet (.local). The names are resolved correctly with and without .local:

$ host portal
portal.local has address 10.22.33.17
$ host portal.local
portal.local has address 10.22.33.17

However, trying to access FQDN fails:

$ ping portal
PING portal.local (10.22.33.17) 56(84) bytes of data.
64 bytes from portal.local (10.22.33.17): icmp_req=1 ttl=64 time=0.171 ms
^C
--- portal.local ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.171/0.171/0.171/0.000 ms

$ ping portal.local
ping: unknown host portal.local

/etc/resolv.conf:

search local
nameserver 10.22.33.1
nameserver 8.8.8.8
nameserver 8.8.4.4

Where can be the origin of this?
Thanks

Update: a solution was found. In /etc/nsswitch.conf I replaced

hosts:      files mdns4_minimal [NOTFOUND=return] dns mdns4

with

hosts:      files mdns4_minimal dns [NOTFOUND=return] mdns4

That solved the problem.

What does dnsdomainname report ?
I believe that without a defined "domain local" in the /etc/resolv, then the resolv library uses your dnsdomainane or equivalent (hostname after the 1st period).

My hunch is you set your hostname to 'foo' instead of 'foo.local' so then the resolve on that system has to create a domain name from the search strings. So your system is trying to resolve
portal.local.local
which of course fails.


If the command
dnsdomainname
returns "(none)". Then edit /etc/sysconfig/network do you have something like
NETWORKING=yes
HOSTNAME=yourhost.local

then reboot or manually set the hostname
