KD5EOC-10 RMS Gateway

Submitted by KD7CAO on Mon, 12/07/2009 - 15:46.

In the process of building a new RMS Gateway for the Denton County EOC. The current RMS has been plagued with unauthorized changes or closing of the RMS Software. Will be moving the RMS Gateway to a new computer and placing it behind a locked door. Hopefully, this will alleviate the issue we've experienced.

RMS Packet Status Report Lag (Why ?)

Submitted by kb9byp on Fri, 01/22/2010 - 16:50.

Hello All:

My system has been online for several years. I started out as a TelPac node and when required migrated to an RMS Winlink node. My question is as follows: When I check my RMS Packet Status online, it sometimes says "current" & at other times says "2 hours old" and so on. It currently says "14 hours old" at this time and I'm sure if I check back later it will say "current". I believe everything is setup properly, and am wondering why at times it shows it has not checked in or seems to be AWOL for no apparent reason? I guess I still don't know how the system works...

Thanks,
Jeff

RMS software periodically sends small status reports using the UDP protocol to the Winlink Servers. UDP is a protocol that does not guarantee delivery. Unlike TCP, it has no "connect", "Ack" and resend capability, but it takes little bandwidth and is efficient by simply sending "beacons".

Somewhere between you and the Wl2K server is congestion or something causing the server not to hear your packets regularly. It may be within your LAN, at your router, at your ISP, or anywhere, including at the WL2K server and it's LAN. We check performance hourly and know when we have an issue at our end. You can do the same, too, by using a protocol analyzer to see what your system's traffic looks like. Check out "Wireshark" a free program you can run on your machine. Get ready for an advanced networking education to make sense of it, however.
