We can mount a remote filesystem (username@servername:/remotefilesystem) in a local mountpoint (/local_mountpoint) with SSHFS:
sshfs -C -o idmap=user username@servername:/remotefilesystem /local_mountpoint
-C use compression
-o idmap=user translate user ID of connecting user to allow local editing/saving of remote files.
To unmount use:
fusermount -u /local_mountpoint
you may have to use administrative privileges.
