Try running mount with the "-v" (verbose) switch.
If this still doesn't solve the problem, let's see a representative NFS entry from /etc/fstab.
I added the address to the /etc/host file. I then ran the mount command as you suggested. Here are the results:
Code:
sudo mount -v -all
[sudo] password for butch:
none : ignored
/media/Data_Three : already mounted
/media/Data_Two : already mounted
/media/Data_One : already mounted
/media/Data : already mounted
/media/butch/Ubuntu_Data_Back: already mounted

I then tried to ping cp2 using its address and received the following:
Code:
ping 192.168.1.102
PING 192.168.1.102 (192.168.1.102) 56(84) bytes of data.

Finally, I tried the following:
Code:
nmap -Pn 192.168.1.102
Starting Nmap 7.60 ( https://nmap.org ) at 2020-08-27 13:13 EDT
Nmap scan report for cp2 (192.168.1.102)
Host is up (0.047s latency).
All 1000 scanned ports on cp2 (192.168.1.102) are filtered
Nmap done: 1 IP address (1 host up) scanned in 5.89 seconds
I also restarted rpcbind on the server in the order that TheFu suggested. So all I have ascertained (as far as my limited knowledge goes) to this point is that my NFS server is on the network, but it is unreacheable.
One final point. I checked /run/resolvconf/resolv.conf, and it contains the following:
Code:
Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 127.0.0.53
search triad.rr.com[/QUOTE] triad.rr.com is an old URL. How can I change this? I also ran the following:[QUOTE]systemd-resolve --status
