Compressed Serial Line Internet Protocol (CSLIP) and Serial
Line Internet Protocol (SLIP) are serial protocols which are used
to facilitate TCP/IP networking over an asynchronous line. A common
use is for a local system to dial in over modems to a DTC, which
completes the connection to a remote HP 9000 system on the network.
Here are the steps required to set up an HP 9000 dial-in connection
using the DTC, CSLIP or SLIP and Telnet Port Identification. Refer
to the appropriate product documentation for how to configure specific
parts of the connection.
Set up the DTC port using the OpenView DTC Manager. (The connection
must have binary mode enabled on the DTC modem port. This can only
be done on a DTC that is managed by a PC-based DTC Manager.)
Assign a dedicated pty for the incoming connection
by configuring the dp entry in the /etc/ddfa/dp
file. Run dpp on the dp
file to activate the changes. This step must be done on the remote
host.
Fill in the entries in the CSLIP or SLIP configuration
files (ppl.remotes) on both the local and
remote hosts. In the ppl.remotes file on
the remote host, for the serial line parameter, enter the name of
the dedicated device file, as defined in the previous step. Remember
that this device entry need not contain a pcf.
Use the Using Serial Line IP Protocols
manual for examples of configuring local and remote ppl.remotes
files.
Configure the HAYES-compatible modem attached to
the DTC according to manufacturer's instructions. The maximum dial-in
speed supported by HP for CSLIP or SLIP over DTC connections is
9600 baud. The modem should also be configured for flow control
off.
Run ppl on the local host
on the IP address of the remote host, as described in the SLIP
manual.
CSLIP/SLIP dial-in connections over DTCs are supported in
binary mode, at speeds of up to 9600 baud for HP 9000 Series 700
and 800 hosts running either HP-UX 9.x or 10.0. They are only supported
in DIAL-IN mode, since DTC ports cannot be used to dial out. See
the SLIP manual for other applications, such
as dialing in and out over HP-MUXes.
