peer_system_name Keyword

The peer_system_name keyword takes a slightly different argument for a dial-in machine than a dial-out machine. For a dial-in server, this argument is the login name used by the remote host when it tries to establish communications with the server. This user name must already be present in the server's /etc/passwd file. When the login service reads this name, it verifies the user name in the /etc/passwd and /etc/shadow files enabling communications.

In this excerpt from Example 24-2:

path
    interface ipd0
    peer_system_name scarlett
    peer_ip_address nomadc

the argument to peer_system_name is scarlett, indicating that when nomadc logs in to nubian-ppp, it uses the login name scarlett.
