Configure a third DNS entry?

[Andre Lahrmann]

Hey,

I want to configure more than 2 DNS servers for a ESXi 5.1 host.

Per vSphere-Client, or per DCUI I only can set 2 entries for that.

Is it possible to implement a third DNS server??

Best Regards,

Andre

You can add a third DNS server by using esxcli. Enable SSH on the host and connect to it. Then use the command:

esxcli network ip dns server list

To show your current DNS servers

esxcli network ip dns server add --server=<ip>

To add a third DNS server.

Then check the current DNS servers again by using the first esxcli command. Example:

DNSServers: 172.20.31.10, 192.168.1.1, 192.168.1.2

It will be used, so this is possible.

Maybe when using esxcli..

But don't know if it actually will be used in case the first two doesn't respond.. 

~ # esxcli network ip dns server add -s 8.8.8.8

~ # esxcli network ip dns server list

   DNSServers: 10.xxx.xxx.xxx, 10.xxx.xxx.xxx, 8.8.8.8

~ # cat /etc/resolv.conf

nameserver 10.xxx.xxx.xxx

nameserver 10.xxx.xxx.xxx

nameserver 8.8.8.8

search who.gives
