Installing and Administering PPP

34 Chapter 2
Setting Up PPP Connections
Configuring Outbound Connections
Refer to the ppp.Dialers(4) man page for more information.
In our example, the Dialers file is already installed on robin. Here is
what the entry for the Telebit model 1600 looks like:
T1600 ABORT NO\sCARRIER ABORT NO\sDIALTONE ABORT BUSY \
ABORT RRING\r\n\r\nRRING\r\n\r\nRRING ABORT ERROR \
TIMEOUT 5 "" AT OK-AT-OK ATS111=0DT\T TIMEOUT 60 CONNECT
his elaborate dialer string will cause pppd to abort the connection
attempt if anything goes wrong with the telephone call, then will disable
UUCP spoofing in the modem before dialing the destination telephone
number. Look through the Dialers file for modem entries for your type of
modem. If none are defined, use the dialer entry “GENERIC”.
You can create a separate list of modem descriptions in a file named
Dialers.local. Entries in Dialers.local take precedence over
entries in Dialers. You can use the entries from the Dialers file to
guide you as you create new entries in Dialers.local. See the
ppp.Dialers(4) man page for more information about setting up
dialer entries.
Since your modem may be used for other purposes besides PPP (for
example, UUCP or for interactive users), it is best to set the modem’s
default parameters to accommodate dial-in applications and have
outgoing UUCP or PPP dialers change them if necessary. The
PPP-specific register settings in Dialers or Dialers.local ensure
that an otherwise general-purpose modem will work as well as possible
with PPP for the duration of the PPP session.
/etc/ppp/Systems
The Systems file contains the hostname or IP address of peer systems
and how to connect to them. Entries in the file have the following format:
name when device speed phone_number chat_script
Refer to the ppp.Systems(4) man page for more information.
For our example, the following line is added to the Systems file on robin
to connect to lark:
lark Any ACU 19200 5551212 in:--in: Probin word: mypasswd
This line provides this configuration for robin's connection to lark:
Call what host: lark
When: Any (any day and at any time).
