[SSHFS] how to mount

just a note

Mount synology user folder, view this.

sshfs -o idmap=user user@host:/ local_directory -p 22

Mount synology user folder,

sshfs admin@[IP]:/debug tttt

Umount, view this.

fusermount -u PATH

Current I want log in with user key,

sshfs  -o IdentityFile=/root/.ssh/id_rsa [IP]:/debug tttt

but get:

remote host has disconnnected

still don’t know why
