I tried this sshfs without shell access, but I realized I should ask opposite way
I would love to mount remote file system automatically, over encrypted tunnel preferably using private/public keys.
It should not mean any security risk (no ssh login or so), only reading/writing to remote sub-folder (like NFS over openVpn / unlike sshfs)
It should preserve user, groups, permissions
It should be easy to configure (like sshfs / unlike NFS overVpn)
It should be in standard repositories (linux)
It should reconnect if connection drops (or ip change)
Is there such thing or am I asking too much ?
