when it authenticates itself to other systems, and also when it

(at least) the name of a client, the name of the server, and a secret

For a full explanation of the format and usage of the /etc/ppp/chap-

6.12 mgetty configuration
The next two entries in the menu allow you to alter the mgetty
configuration files, /etc/mgetty+sendfax/mgetty.config and
/etc/mgetty+sendfax/login.config.
Clicking on either of these entries brings up a page in the work area
which enables you to edit the file and its attributes directly, in the
same manner as the PPP configuration files above.
The Web interface does not check that the content of the files will be
understood. You should ensure that the file is valid before committing
any changes, referring to the Linux manual page for mgetty(8) if you
are unsure.
When you have finished editing a file, clicking Save changes will write
the changes to disk. The changes will not take effect, however, until all
mgetty services are restarted. You can restart all running mgetty
services by clicking Restart mgetty; whilst this occurs, the network will
be briefly unavailable.
mgetty.config
The file /etc/mgetty+sendfax/mgetty.config is the main
configuration file for mgetty.
For full details on the format of the file and the options available, see
the explanatory comments within the file, or the Linux info
documentation for mgetty.
login.config
Normal user logins are handled by the program /bin/login. However,
you may want to run a different program to handle logins by certain
users. You can do this by editing the file
/etc/mgetty+sendfax/login.config.
For full details on the format of the file, see the explanatory comments
within the file, or the Linux info documentation for mgetty.
