With sshfs you can mount remote filesystem locally via ssh. It uses FUSE underneath. Very quick and convenient.
On server:
You need to enable sftp from /etc/ssh/sshd_config.
Uncomment following line if it’s commented:
Subsystem sftp /usr/libexec/sftp-server
And restart sshd.
On client:
Create a mountpoint:
mkdir mount_shared
sshfs user@server:/home/user/share mount_shared/
I am using 9.0 stable on server and 10.0 current on client.
sysctl vfs.usermount=1 is not needed as suggested by others.
sshfs_debug is useful to get debugs.
