Important File Locations

The Digi CM 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 is booted. The file is /usr/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 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.
