DHCP: hostnames of clients not resolving after update v1.2.3 -> 1.2-rolling
Closed, ResolvedPublicBUG

Description

From forum: https://forum.vyos.io/t/dhcp-hostnames-of-clients-not-resolving-after-update-v1-2-3-1-2-rolling/4393

using set service dhcp-server hostfile-update

VyOS should be able to resolve hostnames of clients supplied with an IP address using DHCP. with v1.2-rolling-201911170217 VyOS fails to resolve these hostnames. this worked when using v1.2.3

the hosts file (VyOS 1.2-rolling-201911170217) seems to be correct:

[email protected]:~$ cat /etc/hosts
