Dial-Up links are the most commonly used PPP links. This section includes the following information:
Planning information for a dial-up link
Explanation of the sample link that is used in Setting Up a Dial-Up Point-to-Point Protocol Link
Typically, you only configure the system at one end of the dial-up PPP link, the dial-out system, or the dial-in server. For an introduction to dial-up PPP, refer to Dial-Up PPP Overview.
Before you configure a dial-out system, gather the following information:
Maximum modem speed – Refer to documentation that was provided by the modem manufacturer.
Modem connection commands (AT commands) – Refer to documentation that was provided by the modem manufacturer.
Name to use for dial-in server at the other end of the link – Create any name that helps you identify the dial-in server.
Login sequence that was required by dial-in server – Contact the dial-in server's administrator or ISP documentation if dial-in server is at the ISP.
Before you configure a dial-in server, gather the following information:
Maximum modem speed – Refer to documentation that was provided by the modem manufacturer.
User names of people who are permitted to call the dial-in server – Obtain the names of the prospective users before you set up their home directories, as discussed in How to Configure Users of the Dial-In Server.
Dedicated IP address for PPP communications – Obtain an address from the individual at your company who is responsible for delegating IP addresses.
The tasks to be introduced in Setting Up a Dial-Up Point-to-Point Protocol Link address a small company's requirement to let employees work at home a few days a week. Some employees require the Oracle Solaris OS on their home systems. These workers also need to log in remotely to their work systems on the corporate Intranet.
The tasks set up a basic dial-up link with the following features:
The dial-out systems are at the houses of employees who need to call the corporate intranet.
The dial-in server is a system on the corporate intranet that is configured to receive incoming calls from employees.
A style of login found in UNIX systems is used to authenticate the dial-out system. Stronger Oracle Solaris PPP 4.0 authentication methods are not required by the company`s security policy.
The following figure shows the link that is set up in Setting Up a Dial-Up Point-to-Point Protocol Link.
Figure 5 Sample Dial-Up Link
In this figure, a remote host dials out through its modem over telephone lines to Big Company's Intranet. Another host is configured to dial out to Big Company but currently is inactive. The calls from remote users are answered in the order received by the modem that is attached to the dial-in server at Big Company. A PPP connection is established between the peers. The dial-out system can then remotely log in to a host system on the Intranet.
