Hi, just created bug #445 against radwho .c of version 1.1.6: option -D allows to specify the radutmp file directly. AFAICT, this is the only information that is actually used by reading radiusd.conf, so specifying -D would make reading config file and/or -d obsolete. Has the additional advantage that multiple radutmp instances can be read without pain (i.e. creating different raddb-like directories to tell radwho where to look) and that radwho can be executed as non-root respectively non-sticky bit: only the permissions of radutmp have to be taken into account, not the entire raddb directory.
