I have a proxy server configured to proxy to the NULL realm. This has worked fine until recently when it has started to silently drop RADIUS requests rather than forward them. The NAS does not recieve any response and so rejects users.
My hypothesis is that the RADIUS server it is proxying to becomes unresponsive temporarily, and so the proxy server marks it dead. Thus, when the next RADIUS requests comes along it has no server to proxy it to, thus it returns an error about the realm. Would this hypothesis be consistent with the "No such realm NULL" error? A possible flaw in this hypothesis is that the "dead time" is configured at ten minutes (dead_time = 600) yet the server continues to drop RADIUS packets beyond this time. I would be interested in any ideas or suggestions to fix this. many thanks, josh. -- ----------------------------------------------------------- Josh Howlett, Networking & Digital Communications, Information Systems & Computing, University of Bristol, U.K. 'phone: 0117 928 7850 email: [EMAIL PROTECTED] ------------------------------------------------------------ - List info/subscribe/unsubscribe?
