NOTES:
Don't forget to create %%PREFIX%%/etc/frox.conf 
from %%PREFIX%%/etc/frox.conf.sample and then run frox by 
%%PREFIX%%/etc/rc.d/frox.sh start

Or you can run frox with inetd this way:
* uncomment 'FromInetd yes' in your %%PREFIX%%/etc/frox.conf (so frox
would not run on startup by %%PREFIX%%/etc/rc.d/frox.sh)
* add this line in /etc/inetd.conf:
frox     stream  tcp     nowait  nobody    %%PREFIX%%/sbin/frox    frox
* and assign port number for frox you want in /etc/services (e.g. 2121):
frox	2121/tcp
