Networker Client: A host address mismatch is detected

Hello,

We are currently in the process of installing 8.2.2.0 clients onto our centos 7 and Red Hat 7 boxes. We are at comfortable point but trying to figure out why we are running into a couple of issues. We are running an internal bind server which also happens to be the machine we are placing the client onto. First off we have client 'A' and nsr server 'B', client 'A' uses the internal dns while the nsr server 'B' does not and uses all /etc/hosts configs.

So here are the error logs produced on client 'A'.

03/17/2016 01:52:31 PM  2 1 13 1384093504 3855 0 client'A' nsrexecd SYSTEM warning Cannot resolve host nsrserver'B' to '10.18.1.17', the DNS or client may be misconfigured.

03/17/2016 01:52:31 PM  2 5 0 1056954112 3855 0 client'A' nsrexecd NSR warning A host address mismatch is detected for nsrserver'B''.

We have confirmed that dns works fine, when performing an nslookup on nsrserverB all resolves fine. When pinging all resolves fine. On the nsrserverB side where you have the /etc/hosts configured we have client 'A' within able to ping etc.

We did make a change in /etc/nsswitch.conf

#hosts:     db files nisplus nis dns

hosts:      dns files myhostname

which fails, so we reverted back to files dns myhostname

The issue is using this setup produces the above logs, however the momment we place 10.18.1.17 nsrserverB into client 'A's /etc/hosts file the issue instantly goes away and we are able to browse it's save set via NMC.

*Additional info*

    100000    2   udp    111  portmapper

We have also disabled firewalld throughout these tests, also disabling selinux.

Although we technically have a working client here, can anyone provide any insight into why this implementation only works when Client 'A' has an /etc/hosts entry for nsrserver 'B' even though the dns resolves fine?

Also for reference when installing this we had to create the servers file located in /nsr/res/

Thanks,

Justin
