— Function: url-open-stream name buffer host service

Open a stream to host, possibly via a gateway. The other arguments are as for open-network-stream. This will not make a connection if url-gateway-unplugged is non-nil.

— Variable: url-gateway-local-host-regexp

This is a regular expression that matches local hosts that do not require the use of a gateway. If nil, all connections are made through the gateway.

— Variable: url-gateway-method

This variable controls which gateway method is used. It may be useful to bind it temporarily in some applications. It has values taken from a list of symbols. Possible values are:

telnet

Use this method if you must first telnet and log into a gateway host, and then run telnet from that host to connect to outside machines.

rlogin

This method is identical to telnet, but uses rlogin to log into the remote machine without having to send the username and password over the wire every time.

socks

Use if the firewall has a socks gateway running on it. The socks v5 protocol is defined in RFC 1928.

native

This method uses Emacs's builtin networking directly. This is the default. It can be used only if there is no firewall blocking access.
