Important File Locations

The Digi CM unit has several files that are important for administrative use.

Below is a brief listing of some files that the root user or system administrator

might desire to either monitor or edit.

Default Script

The default script file is executed whenever the Digi CM unit is booted. The file

is /usr2/rc.user and can be modified with the vi editor. The modified script

becomes effective when the system is rebooted.

Booting Sequence

When the Digi CM unit boots, it decompresses the /cnf/cnf.tar.gz file to /tmp/

cnf/* and unmounts the /cnf file. If the configuration files are modified in the /

tmp/cnf file and the configuration is saved to flash (saveconf), the unit mounts

the /cnf file and compresses the /tmp/cnf/* to /cnf/cnf.tar.gz.
