The connection methods described in this section are based on GVFS http://en.wikipedia.org/wiki/GVFS. Via GVFS, the remote filesystem is mounted locally through FUSE. TRAMP uses this local mounted directory internally.
The communication with GVFS is implemented via D-Bus messages. Therefore, your Emacs must have D-Bus integration, see (dbus)D-Bus.
This method provides access to WebDAV files and directories. There exists also the external method davs, which uses SSL encryption for the access.
Both methods support the port number specification as discussed above.
OBEX is an FTP-like access protocol for simple devices, like cell phones. For the time being, TRAMP only supports OBEX over Bluetooth.
As you might expect, this method uses
sftp in order to
access the remote host. Contrary to the ssh and scp
methods, it doesn’t open an
ssh session for login.
Therefore, it could be used to access to remote hosts which refuse
ssh for security reasons.
The synce method allows communication with Windows Mobile devices. Beside GVFS for mounting remote files and directories via FUSE, it also needs the SYNCE-GVFS plugin.
This customer option, a list, defines the external methods which shall be used with GVFS. Per default, these are dav, davs, obex, sftp and synce. Other possible values are ftp and smb.
