CMG-DCM

You can specify additional options for each serial port separately using the serial.x.ppp configuration option, which can be found on the Serial port configuration page for that port.

chap-secrets

The file /etc/ppp/chap-secretscontains secrets for pppd to use when it authenticates itself to other systems, and also when it authenticates other systems to itself. Each line in a secrets file contains (at least) the name of a client, the name of the server, and a secret specific to that particular combination of client and server.

For a full explanation of the format and usage of the /etc/ppp/chap- secrets file, see the Linux manual page for pppd(8).

mgetty

This submenu allows you to alter the mgetty configuration files,

/etc/mgetty+sendfax/mgetty.configand /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.

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
