DNS Issue - nslookup works ping and ssh don't

SteveDennis-OracleOct 25 2012 — edited Oct 30 2012
Hi,

I have a weird situation on a development system I am building.

I have set up the DNS client in resolv.conf, giving the search order (three options, separated by spaces) and the IP addresses for the three available DNS naming servers.

When I perform an nslookup for a specified IP address, the correct fully qualified hostname is returned. However, when I perform an nslookup on the hostname, fully qualified and short, the IP address is not found.

When I try and ping or ssh to a hostname, I get the message 'Could not resolve hostname, Name or service not known'

Does anyone have a suggestion as to why this seems to be a one way lookup only???


Many thanks,


Steve Dennis
