Notes

Perforce users can use the Host: field of the p4 client form to specify that a particular client workspace can be used only from a particular host machine. When this field has been set, the P4HOST variable can be used to fool the server into thinking that the user is on the specified host machine regardless of the machine being used by the user. As this is a very esoteric need, there's usually no reason to set this variable.

The hostname must be provided exactly as it appears in the output of p4 info when run from that host.
