I'm not sure what the hostname on my main machine is. How do I check in Linux?

Easy one 👍 In Linux, you can check the hostname a few different ways:

Quick commands

hostname

→ prints the current hostname (e.g. maindesk or ubuntu-pc).

hostnamectl

→ shows more detail (static hostname, pretty hostname, machine ID, etc.).

cat /etc/hostname

→ just the stored hostname.

Example

darren@maindesk:~$ hostname
maindesk

So in your NFS mount command you’d use:

sudo mount -t nfs maindesk:/home/darren /mnt/home_remote

If the hostname doesn’t resolve on your LAN (sometimes home routers don’t share them), just use the IP address instead:

ip addr show

Look for your main network interface (enp*, eth0, wlan0). You’ll see something like:

inet 192.168.254.23/24

Then mount with:

sudo mount -t nfs 192.168.254.23:/home/darren /mnt/home_remote

Want me to show you a quick way to make the hostname resolvable on your LAN (so you don’t have to remember the IP each time)?

Oh, it was main disk. Look at you and your awesome memory.

Haha — perfect 😄 so your hostname really is maindesk (not “main disk” 😉). That means your mount line on the client is as simple as:

sudo mount -t nfs maindesk:/home/darren /mnt/home_remote

If your LAN’s DNS/Bonjour doesn’t resolve maindesk, just fall back to the IP address (192.168.254.xx).

Since this is a fresh setup, do you want me to give you a one-liner to make the mount permanent (so /mnt/home_remote is always there after reboot), or would you rather keep it manual for now while you test?
