When I suggested SSH I didn't mean SSHFS, I never used that.
What I meant was:
- Machine A:
sudo apt install ssh (or install openssh server from software boutique)
- Machine B:
sudo apt install ssh
cd ~/.ssh
ssh-keygen -t rsa -b 4096
ssh-copy-id you@MachineA_IP
[enter your password on Machine A]
Then you should be able to connect to Machine A from Machine B using the rsa key.
Go to Caja, hit CTRL+L and enter:
ssh://you@MachineA:/home/you/
Then you should see your home folder on Machine A inside Caja.
Bookmark it to complete the procedure.
