# Working on multiple computers

By default, your ticket is valid only for the IP address of the computer from which you logged in. If you use P4 Server from multiple computers that share a home directory (typical in many UNIX environments), log in with:

    p4 login -a

Using `p4 login -a` creates a ticket in your home directory that is valid from all IP addresses, enabling you to remain logged into P4 Server from more than one computer.

To log out from all computers simultaneously, issue the following command:

    p4 logout -a

To learn more, see `p4 login` and `p4 logout`.
