Full Discussion: Force ssl/ssh to use the hosts file
Operating Systems Linux Red Hat Force ssl/ssh to use the hosts file Post 302897604 by rbatte1 on Tuesday 15th of April 2014 05:26:55 AM

Inside [CODE] and [/CODE] tags, an you paste the contents of /etc/nsswitch.conf and /etc/resolv.conf so we can look at all the settings. It sounds to me like you are still going DNS first and there is a problem on the DNS servers. I assume that the name you are using is not in DNS, but the DNS should recognise it and return a "not found" sort of response much faster.

Do you have multiple DNS servers and is one broken? Can you do the following to each configured DNS server IP:-
Code:
nslookup known.good.name dns.server.ip.address

Do you get a response in a suitable time? It is possible that you need to adjust your time-out values for your DNS query. There are different ways of implementing the TIMEOUT and RETRY values so you get a sensible response.


Regards,
Robin
