Configuring Outbound Connections
The following files are used for outbound calls:
• /etc/ppp/Devices associates dialer types with physical devices
and speeds. pppd examines the file when it places a call. If no suitable
speed is found or if all devices associated with that speed are busy,
pppd tries again later.
• /etc/ppp/Dialers describes how to dial each type of modem
attached to the HP-UX system that is to be made available for
outbound calls.
• /etc/ppp/Systems contains the hostname or IP address of peers
and how to connect with peers.
• /etc/ppp/Autostart starts pppd for on-demand outbound calls.
/etc/ppp/Devices
The Devices file associates dialer types with physical devices and
speeds. Entries in the file have the following format:
dialer device speed [optional_parameters]
If the PPP connection is a direct connection, the dialer field should be
“Direct.” Refer to the ppp.Devices(4) man page for more information.
In our example, the following entry is made to robin's Devices file:
T1600 cuh00 19200
This line provides this configuration for robin's connection to lark:
Use what modem: T1600 (Telebit model 1600)
On which system device: cuh00 (outbound device)
At what speed: 19200 (19200 bps)
/etc/ppp/Dialers
The Dialers file describes how to dial each modem that is attached to
the local system. The file Dialers is installed with PPP. Entries in the file
have the following format:
