FreeRADIUS dies

Wouldn't it be nice to have a dedicated process that constantly watches another process and the moment it dies, simply restarts this dead process. The deamontools package contains such a program called supervise. If you want to minimize downtime, the following URL describes in detail how to incorporate a check on the radiusd process using the supervise program:

After you have discovered that FreeRADIUS has died unexpectedly, go through the various system log files in order to try to determine what has caused this to happen.

Up till now, we have discussed problems that can prevent FreeRADIUS from starting and performing, and also how to keep it running. The rest of the chapter will look at common problems when clients interact with a running FreeRADIUS server.
