safe_asterisk — A wrapper to run the asterisk executable in a loop


safe_asterisk [ asterisk_params ]


safe_asterisk is a script that runs asterisk in a loop, which can be useful if you fear asterisk may crash.

The script does not run in the background like a standard service. Rather, it runs in its own linux virtual console (9, by default). It also uses the option '-c' of asterisk(8) to avoid detaching asterisk from that terminal.

safe_asterisk also runs asterisk with unlimited core file size, and thus asterisk will dump core in case of a crash.

To get a "picture" of console 9, from another terminal (e.g: from a remote shell session) you can use:

screendump 9

The init script of the Debian package should be able to run safe_asterisk as the asterisk service, if so configured. See coments in /etc/default/asterisk



safe_asterisk runs in that directory, rather than in / as usual.


If core files were generated there, they may be


Files in this directory will be 'source'd by the safe_asterisk script before it starts Asterisk proper, allowing them to set additional environment variables or run any other steps that are needed for your system.


While showing the output on a console is useful, using screen(1) as the terminal may be better.

The script does not read configuration from standard location under /etc

It uses fixed locations under /tmp , and thus may be exposed to a symlink attacks.
