prompt, type the command PPP and press enter. Send the terminal server a “BREAK” from your terminal communication package and await notification that a PPP link has been established. When conformation has been received, you may open up a telnet window and establish a PPP link directly to the terminal server.
When connecting to a remote host via PPP, the are two standard options of authentication: PAP (Password Authentication Protocol) and CHAP (Challenge-Handshake Authentication Protocol). In the PAP authentication process, the terminal server sends the username and the password to the remote host. The remote host then determines whether or not the user is allowed to establish the PPP link.
The CHAP option of authentication offers a higher-level of security since the authentication process is encrypted. In this process, the terminal server and the remote host have a shared secret key. The terminal server transmits the local host name and the remote host responds with a “challenge” number (random number). The “challenge” number is then encrypted with a response back to the remote host, which encrypts the challenge using the same secret key. If the responses match, the PPP session is established.
