NAME adsl-connect - Shell script to manage a PPPoE link

SYNOPSIS adsl-connect [config_file]

adsl-connect interface user [config_file]

DESCRIPTION adsl-connect is a shell script which manages an ADSL connection using the Roaring Penguin user-space PPPoE client. If you omit config_file, the default file /etc/sysconfig/network-scripts/ifcfg-ppp0 is used. If you supply interface and user, then they override the Ethernet inter- face and user-name settings in the configuration file.

Note that normally, you should not invoke adsl-connect directly. Instead, use adsl-start to bring up the ADSL connection.

adsl-connect first reads a configuration file. It then brings up a PPPoE connection. If the connection ever drops, a message is logged to syslog, and adsl-connect re-establishes the connection. In addition, each time the connection is dropped or cannot be established, adsl-con- nect executes the script /etc/ppp/adsl-lost if it exists and is exe- cutable.

The shell script adsl-stop causes adsl-connect to break out of its loop, bring the connection down, and exit.

TECHNICAL DETAILS adsl-connect uses the following shell variables from the configuration file:

ETH The Ethernet interface connected to the ADSL modem (for example, eth0).

USER The ADSL user-id (for example,

PIDFILE A file in which to write the process-ID of the adsl-connect pro- cess (for example, /var/run/ Two additional files ($PIDFILE.pppd and $PIDFILE.pppoe) hold the process-IDs of the pppd and pppoe processes, respectively.

By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections. Just specify the configura- tion file as an argument to adsl-start and adsl-stop.
