After upgrading a workstation from 14.04 LTS to 16.04 LTS, it is unable to connect to the ypserver/NIS. Nothing eventful happened during the upgrade.
Everything is correct as far as the ypbind.conf and nsswitch.conf goes.
The workstation functions fine otherwise, with full view of the network (except the files shared by the server it's supposed to connect with).
The server is running a fully-maintained Ubuntu Server 14.04.5.
When I run:
It gives me:
Test 1: domainname Configured domainname is "mycompanydomain" Test 2: ypbind Can't communicate with ypbind
(obviously "mycompanydomain" is just a substitute for the actual domain we use here)
Also, I have also tried a clean (bare metal, different hard drive) 18.04 install on this same hardware (as opposed to just an in-place upgrade) and I am getting the same results. This same machine runs fine on 14.04.5. And it runs 18.04 fine too, except I just can't seem to connect to the server.
Is there something inherently not NIS/NFS-friendly about versions 16.04 and 18.04; how should I go about troubleshooting this further?
