cmdiag is a Docsis cable modem diagnostic tool. It can get information from Docsis 1.0, 1.1, and maybe 2.0 cable modems. The cmdiag project gathers information from the cable modem via SNMP and displays various cable parameters in real time.
· To successfully install and run this tool you will need these two libraries, Ncurses and Net-SNMP installed on your system.
· Those two libraries have packages for most every Linux distro so don't worry.
