Can't resolve hostname in local network

Hello,

I got a new router from my ISP and ever since I installed it my pc with arch installed cant resolve hostnames in the local network anymore. Specifically I want to connect to my NAS with a browser or mount a nfs share, neither is possible using the hostname of my NAS, it works with the IP address however.

Here is what happens when I try to ping it:

[stefan@belegost ~]$ ping 10.0.0.11
PING 10.0.0.11 (10.0.0.11) 56(84) bytes of data.

[stefan@belegost ~]$ ping nargothrond
ping: unknown host nargothrond

My resolv.conf just looked liked this (before I started trying out things):

# Generated by resolvconf
nameserver 10.0.0.138

I've tried using Googles DNS server or add the ones of my ISP directly, but neither worked.

I'm sorry I can't provide more informations, but I don't know if I'm looking in the right spot, since I have no problems with anything outside my LAN, so I'm not even sure this problem is DNS related.

Re: Can't resolve hostname in local network

Have you added "nargothrond" and it's IP address to /etc/hosts ?

Thanks for the reply, adding the NAS to /etc/hosts works, but since the NAS doesn't have a static IP, this would mean I'd have to change /etc/hosts every time it changes it's IP address.

Re: Can't resolve hostname in local network

You should login to your router and assign a static address to your NAS using the hardware address of the NAS or set a fixed IP address on the NAS.

If this is sorted, you should prepend "[SOLVED]" to your first post.

Re: Can't resolve hostname in local network

You could also use avahi and nss-mdns to enable local hostname resolution using MDNS. You wouldn't need to set static IPs that way : https://wiki.archlinux.org/index.php/Av … resolution
