Adding Search to resolv.conf Prevents FQDN Searches – Fix

domain-name-systemresolv.conf

I added the following line to my resolv.conf to allow for shorthand querying servers on my local domain.

search local.

If I have a server named myserver.local I can ping the server using "ping myserver", however if I try to "ping myserver.local" it stalls and fails to return an IP address. Pinging other hosts, such as google.com works as expected.

Is there a way that I can make both "ping myserver.local" and "ping myserver" work correctly?

You need to remove the . after local:

search local

Assuming you have a dns resolver setup for your local domain, it should work as you're describing.

Do entries in local ‘hosts’ files override both forward and reverse name lookups

Generally the hosts file will be used for both forward and reverse lookups. The preference on a Unix system this will depend on the order of entries in you nsswitch.conf file.

e.g. the line below will make the hosts file override DNS. Reversing the entries will make DNS override the hosts file.

hosts:      files dns

I am not sure if you can tune to order of preference on a windows system.

I have had a look at the source for ping in inetutils-20071127 (the version installed on my Ubuntu 9.04 box) and the source seems to enable numeric only mode if you ping an IP address rather than a hostname:

                if (inet_aton(target, &whereto.sin_addr) == 1) {
                        hostname = target;
                        if (argc == 1)
                                options |= F_NUMERIC;

This could explain why you don't get a reverse lookup when you ping your host by IP address.

Named on AIX (5.3) – DIG won’t find hosts without FQDN

Don't you just need to update your resolv.conf file?

# cat /etc/resolv.conf
domain intranet.domainname.com
search intranet.domainname.com
Nameserver 127.0.0.1
