Thread: adding static host to /etc/hosts

Hello,

I've checked man pages and documentation and I've not been able to find an answer for this:

How do I add a line to genconfig's /etc/hosts? I need to specify the short and long names as well as the IP address of my license server.

Peter

Peter,

You can use addhost to add an unmanaged host:

Code:

[root@master genconfig]# addhost -x 192.168.1.100 -s example.com

Thanks!

During boot, NFS mounts fail from our NAS appliance with host can not be found. I can bypass that by mounting later via /etc/rc.local on head node.

I tried adding the NAS host with -x but this implies adding an unmanaged node.

Is there a way to just add an external host entry?

Hi

An unmanaged node for is simply a node that is not managed by Kusu. It can be a switch or a NAS appliance, in your case.

Is the NAS appliance hostname resolvable in your lan DNS? Can you provide the output of /etc/resolv.conf and /etc/named.conf.

These files are looking good. Again, once the head node boots, mount -a has no problem. I think it has to do with the timing of when NFS mounts are done in the boot sequence. I could reorder that but the save bet is to just add that mount command in /etc/rc.local

Can you also provide the original fstab before the mount entry has been moved to rc.local?
