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

ipa-dns-install

ipa-dns-install(1)						 IPA Manual Pages						ipa-dns-install(1)

NAME

       ipa-dns-install - Add DNS as a service to an IPA server

SYNOPSIS

       ipa-dns-install [OPTION]...

DESCRIPTION

       Adds DNS as an IPA-managed service. This requires that the IPA server is already installed and configured.

OPTIONS

       -p DM_PASSWORD, --ds-password=DM_PASSWORD
	      The password to be used by the Directory Server for the Directory Manager user

       -d, --debug
	      Enable debug logging when more verbose output is needed

       --ip-address=IP_ADDRESS
	      The IP address of the IPA server. If not provided then this is determined based on the hostname of the server.

       --forwarder=FORWARDER
	      A  forwarder  is a DNS server where queries for a specific non-resolvable address can be directed. To define multiple forwarders use
	      multiple instances of --forwarder

       --no-forwarders
	      Do not add any DNS forwarders, send non-resolvable addresses to the DNS root servers.

       --reverse-zone=REVERSE_ZONE
	      The reverse DNS zone to use

       --no-reverse
	      Do not create new reverse DNS zone. If used on a replica and a reverse DNS zone already exists for the subnet, it will be used.

       --zonemgr
	      The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN

       -U, --unattended
	      An unattended installation that will never prompt for user input

EXIT STATUS

       0 if the installation was successful

       1 if an error occurred
