4.5 Gateway methods

Gateway methods are for proxy host declarations (see Multi-hops) so as to pass through firewalls and proxy servers. They are not like the other methods that declare direct connections to a remote host.

A gateway method always comes with a port setting. TRAMP targets the port number with the gateway method localhost#random_port from where the firewall or proxy server is accessed.

Gateway methods support user name and password declarations for authenticating the corresponding firewall or proxy server. Such authentication can be passed through only if granted access by system administrators.


This method implements an HTTP tunnel via the CONNECT command (conforming to RFC 2616, 2817 specifications). Proxy servers using HTTP version 1.1 or later protocol support this command.

For authentication, this protocol uses only Basic Authentication (see RFC 2617). When no port number is specified, this protocol defaults to 8080.


The socks method connects to SOCKSv5 servers (see RFC 1928) and supports Username/Password Authentication.

The default port number for the socks server is 1080, if not specified otherwise.
