Configuring the Serial Line Internet Protocol (SLIP)

Configuring an incoming link

An incoming SLIP link permits the local system to accept an incoming SLIP connection request from a remote host. This type of link requires a login account in the /etc/passwd file on the local host. A remote host wishing to initiate a SLIP link with the local host must use an outgoing type of link, and must specify this account name and its associated password in the chat script in the entry for the local system in the remote system's UUCP Systems(4bnu) file.

When you use the Network Configuration Manager to configure this type of link, it creates a SLIP login account which uses a special shell script instead of a standard shell. The shell script must execute an slattach command to establish the SLIP link. You must configure the remote side to use an outgoing link type for its end of the link.

Provide the following information to configure an incoming link:

Login name for SLIP: The name of the account used to service SLIP sessions.
Login shell script: The name of the script containing the slattach command that is used to establish the link.

You must create the login shell script for the user that you name. The script should be owned by the SLIP user and it must be executable by them. It should contain a line to start slattach similar to the following:

   /usr/sbin/slattach /dev/term/00 132.147.118.6 132.147.246.12 255.255.0.0 38400 &

In this example, SLIP accepts incoming requests from the system 132.147.246.12 via the interface 132.147.118.6 on a modem connected to /dev/term/00. The baud rate in this example is 38400. For more information, see slattach(1Mtcp).
