Configuring UUCP for dynamic outgoing links
Dynamic outgoing SLIP links
use the UUCP facilities as the physical media over which
the link is made.
These media usually consist of modems at the remote and local
hosts, and the telephone lines connecting the modems.
After you configure a dynamic outgoing SLIP link with the Network Configuration Manager, you must edit the UUCP Systems and Devices files to define information about the remote site. You can also use uuinstall(ADM) to perform this task.
A dynamic outgoing SLIP link, defined in /etc/tcp, must specify the UUCP name for the remote site (uucp_sitename) as the argument to the -d option. (slattach will fail if you specify -d but not uucp_sitename. If you do not specify -d, slattach erroneously tries to configure a dedicated link instead of a dynamic outgoing link.) uucp_sitename must exist as a ``sitename'', listed in the UUCP file /usr/lib/uucp/Systems, which identifies the remote host. This forms the link between SLIP and UUCP.
An entry for uucp_sitename may be entered in the /usr/lib/uucp/Systems file (see Systems(F)) by manually editing this file or by running uuinstall(ADM), which prompts you for the necessary information. The login name and password associated with the account must match those defined by the SLIP configuration at the remote end.
SLIP's use of UUCP in establishing a connection requires that UUCP can be used alone to connect the local and remote hosts without using SLIP. When a dynamic outgoing SLIP link is brought up, SLIP requests a UUCP link to the remote host. UUCP must be able to establish a UUCP link using only UUCP information, such as that found in the files /usr/lib/uucp/Systems, /usr/lib/uucp/Devices, and /usr/lib/uucp/Dialers. During UUCP link establishment, characteristics such as baud rate and flow control are determined by the UUCP information and not by the SLIP link configuration. Once UUCP has established a link, it informs SLIP of the tty to use for that link. At this point SLIP takes over the link. Therefore, it is best to test a UUCP link between the local and remote hosts before trying to run SLIP over the link.
For complete information on configuring a UUCP link, see Chapter 7, ``Connecting to other computers with UUCP'' in the System Administration Guide.
