I'm presently only using Radiator in a fairly new network (but working to extend that to many other locations). This new network has six sites, one directly on the Ethernet with the servers and five remote via frame-relay. Radiator has been working like a charm on the Ethernet site for more than a month, but the remote sites just came up last week. What I see for these sites is a lot of failed access requests. The NAS, a PortMaster 3, sends the request, Radiator approves it and sends back an accept, then the NAS sends a duplicate access request about three seconds later. Radiator ignores the duplicate request, but the NAS sends another one a few seconds after that which is also ignored. This is repeated several times before the user gives up. However, it isn't consistent. About 40% of the accepts are successful, no duplicate requests are received, and the caller is connected. Looking at the Radiator log, it seemed clear that the accept was not making it back to the NAS for some reason. I changed the DupInterval parameter for Radiator to zero and now all valid callers are authenticated successfully. The log file still indicates that there are duplicate requests but now they are being ignored. Eventually, usually after two or three failures, the NAS hears the accept and the caller is connected. This makes no sense to me. We are using PortMaster 3s in over a hundred sites around the world and have never seen this problem. But only in this one network are we using Radiator. The network itself does not seem a candidate for the problem; it is almost completely unloaded still and the accepts did sometimes work. BTW, I saw no failures of accounting requests. Maybe the NAS doesn't care about getting a reply for those? What problems will we experience if I leave the DupInterval set to zero? Or, alternatively, are there any other suggestions for how to solve this problem? -- Dave Close Quik Internet +1 949 548 2171 Costa Mesa California [EMAIL PROTECTED] http://www.quik.com/ === Archive at http://www.thesite.com.au/~radiator/ To unsubscribe, email '[EMAIL PROTECTED]' with 'unsubscribe radiator' in the body of the message.
