Well, if the interface isn't being configured in /e/n/i then either it's
using NetworkManager or it's using systemd-networkd. Or something that
you set up by hand.
westk@westkent:~$ ps as | grep NetworkManager

'systemd-resolved' will handle your DNS.
Is /etc/resolv.conf a symlink (if yes, to where)?
westk@westkent:~$ ls -lah /etc/resolv.conf
lrwxrwxrwx 1 root root 31 Jul 13 11:22 /etc/resolv.conf ->
/run/NetworkManager/resolv.conf
What is the output of:
$ cat /etc/resolv.conf
westk@westkent:~$ cat /etc/resolv.conf
# Generated by NetworkManager
search acu.local
nameserver 150.252.131.127
nameserver 150.252.134.8
nameserver 150.252.134.159
(this is after I manually removed the bad entry and replaced it with the
good)
Is there a way to test, from my client, what my ord's DHPC server is giving
me for DNS entries, to double-check my network admin's findings?
Possibly, but I don't know how NM works.
Some hints:
The best way is to be sure of what the dhcp server is dishing out
assuming you can access it.
If you are ready to get dirty and break your "system":
1) Empty /etc/resolv.conf (clear the content of the file, that way, you
don't remove the symlink)
2) Remove any configuration relative to DNS (/etc/network/interfaces ...)
3) Restart NM
4) The file /etc/resolv.conf should be populated with the DNS given by
your dhcp server
You might have some luck looking in the directory:
/var/lib/dhcp
