I have Arris router with DNS enabled and IP address reservation so all boxes get static IPs. Windows 10 boxes can resolve all local hostnames. The gentoo box cannot resolve any other hostnames. zenithU is the gentoo box. panther is the windows box. Please help.

Code:
$cat /etc/resolv.conf
# Generated by net-scripts for interface enp6s0
search myhomenet.com
nameserver 192.168.0.1


Code:
$cat /etc/conf.d/net
config_enp6s0="192.168.0.2 netmask 255.255.255.0 brd 192.168.0.255"
routes_enp6s0="default via 192.168.0.1"
config_enp5s0="192.168.22.1/24 brd 192.168.22.255"


Code:
$cat /etc/nsswitch.conf

Hi,

first off, please use code tags next time!

second: Windows usually use NetBIOS or WINS for resolving names in a local network first, before using DNS. You should either setup a DNS server in your local network which will be asked for local hostnames or you add all hosts (since you have static dhcp) to your /etc/hosts.

greets, bb

Unless you actually own the domain name "myhomenet.com" (74.117.114.119, which is correct), you probably shouldn't configure your system to blindly trust it to handle all relative hostnames (those without a dot at the end).

Yep changed that domain named to one with dot at the end.

Starting winbindd resolves the internal hostnames now. It had to be configured in /etc/conf.d/samba

Thanks all
