(RADIATOR) Some errors with VPN and POPTOP

Hi!

I was trying to use Radiator with POPTOP and despite the fact that it works
(having to wait for a couple of minutes for the accounting procedure to
timeout) it comes up with these errors:

VPN LOGs
--------
Jun  8 12:27:24 fw pppd[23742]: rc_ip_hostname: couldn't look up host by
addr: C0A80105
Jun  8 12:27:24 fw pppd[23742]: rc_send_server: no reply from RADIUS server
unknown:1813
Jun  8 12:27:24 fw pppd[23742]: Accounting START failed for XXXXXXXXX



What do you think the problem is?
In
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/radiusclient-ng/radiusclient-ng/li
b/ip_util.c?rev=1.5 in function rc_ip_hostname, is says something about
reverse dns "gethostbyaddr"...


Thank you,

António Fernandes
