Quick note, this is the favored incantation to prevent too many instances of lost connections.

mkdir /local/mount/point
sshfs -o allow_root,reconnect,ServerAliveInterval=15,ServerAliveCountMax=3  user@remotelocation:/path/to/folder /local/mount/point

The extra arguments are the real magic here. If you notice, some of those help reestablish the connection - in practice, this means that sometimes it will come back after putting your laptop to sleep. I tend to put specific commands for specific mounts into scripts. However, you can also just put the first part with the ‘incantations’ into a bash alias.

nano ~/.bashrc

Add this to the end:

alias shfs='sshfs -o allow_root,reconnect,ServerAliveInterval=15,ServerAliveCountMax=3 '

Then you can simplify mounting, and make it very similar to scp and ssh:

mkdir /local/mount/point
shfs user@remotelocation:/path/to/folder /local/mount/point
