Using environment variables

To configure connection settings using environment variables, set P4PORT to protocol:host:port, as in the following examples:

If the server runs on	and listens to port	supports encryption protocol	set P4PORT to
your computer	1666	nothing (plaintext)	localhost:1666
perforce	1666	SSL	ssl:perforce:1666
houston	3435	nothing (plaintext)	tcp:houston:3435
example.com	1818	SSL	ssl:example.com:1818

If you do not specify a protocol in your P4PORT setting, tcp: (plaintext communication over TCP/IP) is assumed. If the Helix Server has been configured to support SSL, you can encrypt your connection to Helix Server by using ssl: as the desired protocol.

Other protocols (for example, tcp4: to require a plaintext IPv4 connection, or ssl64: to require an encrypted connection, but to prefer the use of the IPv6 transport instead of IPv4) are available for use in mixed networking environments.

See Configure for IPv6 networks, and the Helix Core Server Administrator Guide, for details.
