Hello,
My linux machine is not happy with dns.
I have a NAS, and if I try ping NAS there is no correct response.
if I enter dig NAS:

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> NAS
;; global options: +cmd

In fact, the server as a static address and I enter the internet router address as a DNS server in the etc/network/interfaces file.
Is that correct ? is a home internet router DNS ?
With a window computer if I enter ping NAS, the resolution is ok, but I know windows can use multipls strategys to make the name resolution.

Many thanks for your help.
Best regards

actually it depends on how your router configured. You can use the DNS service of the router, in that case it is ok. Also your NAS can request an IP from the router, and register itself on the router (and NAS will be known)

Hello,
Many thanks for your reply.

In the router the DHCP is enabled but I use static adress.
The NAS is set with fixed address.

From windos I can ping the NAS using the name but not with the linux server.

In this condition is the Netgear 4000 home router acting as a DNS server ?

Must I install a DNS service for the linux server ?

Best regards

Thierry

I have not looked at the manual for your router yet but mostly likely name resolution is being handled by SMB/CIFS which is the windows file and printer networking protocol.

This is why ping works for windows but not linux. It is possible to configure samba for SMB/CIFS name resolution but the easiest fix would be to add a entry in your /etc/hosts file for the NAS.

You do not need to install dns service for linux, you need to use that service on the router (if there was a checkbox to switch it on/off). But you can do what michaelk suggested, just add it to /etc/hosts on your linux.
