Cam Manager under Debian Like

After my latest install, i discover the WebCam can’t be disable except in CLI. I have write a small Python program, to have a graphical “action” instead load/unload the module from the command line.

You can use/fork/update. The project is available on GitHub.

FreeRadius and Dnsmasq

I use DNSmasq to manage my local DHCP/DNS server, but unfortunatly there is no plugin’s or wrapper for FreeRadius. I have coded a quick and dirty Python program to do this:

  • Generate an authorize file
  • Generate and authorized_macs file (no more require with my settings)

My next step is use the “tag” with the “set:” section from dnsmasq for mark the vlan ID (for exemple set:vlan10).this code is also available on GitHub.

After launching the script, copy the authorize_conf file in the files folder in the freeradius 3.0 directory.

i use the $INCLUDE value in the default.conf for include it.
