I've just been doing some research on the net and found this link on the GNU radius client reference page:

It looks as if the radtest client has reserved characters.

The characters are *escaped*, not *reserved*.

Does anyone know if this applies to shared secrets with the Freeradius server as well???

The shared secrets in FreeRADIUS have *no* reserved characters. They *can* be double-quoted strings, with all of the usual conditions for escaping characters. This is less of a FreeRADIUS-specific issue than a standard Unix way of doing things. Alan DeKok.
