[SOLVED] vSphere Client Hostname Issue

Rory Glenn Pascua · 03-08-2012, 09:59 AM

I can access some of my stacks via hostname and some via IP address like so:
1. ssh root@stack1.vm.org.net
2. ssh root@130.72.86.13

What config changes do I need to make so I can access all my stacks via Hostname? I get this error message when trying to access a stack using option 1 above. "Could not resolve hostname stack1.vm.org.net: Name or service not known"

Here's what I've done so far:

1. I looked at an old stack and compared network settings with a new stack
2. I checked firewall settings

The easiest way is to add each of the stacks to /etc/hosts on the system from which you're doing the ssh. More complicated would be to setup DNS or NIS to keep track of all the hosts in your domain then modify /etc/nsswitch.conf (to tell it to use DNS or NIS) and /etc/resolv.conf if you go the DNS route.

It depends on how many systems you have as to whether it makes sense to do DNS or NIS. In most commercial shops there are dozens or hundreds of systems so setting up DNS is what most folks do.

Thanks. I figured it out. I went the hard way on this one and modified the DNS. This issue has been resolved. Sadly I can't post my solution because it's way too long and complicated and would require more time to explain than the amount of time I spent solving the problem. I'd be more than happy to help anyone though.. do a walk through, gchat and so forth.
