- I wonder if anyone might be able to shed some light on a strange
- problem I'm seeing.
-
- I've got about 100 Macs (variety of models) and a few PCs on my local
- network. The local network consists of 3 zones, 1 ethernet and 2
- LocalTalk. The ethernet is used for a few UNIX workstations, Mac mail
- and file servers, and as a local backbone for the 2 LocalTalk
- segments. The LocalTalk segments each consist of 4 interconnected
- Farallon StarController hubs, and a Cayman GatorBox CS gateway. The
- ethernet segment is connected through a cisco router and 57Kb
- dedicated line to the corporate network.
-
- In one of the 2 local LocalTalk segments I've got an SE/30 with 8 MB
- RAM running 7.0.1 + Tune-up 1.1.1, KeyServer 3.0.5 (50 clients), and
- Meeting Maker Server 1.5. This machine is a dedicated
- KeyServer/Meeting Maker host, and I've enabled file sharing so that I
- can occasionally access the disk from remote for administrative
- purposes.
-
- I recently began using TrafficWatch II 1.0A to analyze network
- utilization, and I noticed that this SE/30 was sending a substantial
- number of packets to a nonexistent device in the same zone. I can't
- resolve the recipient address to any device. This mysterious device
- receives packets only from the SE/30, and never sends packets to the
- SE/30, or any other device.
-
- Upon closer inspection (using LocalPeek), I noticed that the packets
- being sent by the SE/30 to the mystery device consist entirely of
- lapRTS.
-
- Does anyone have any insight into this strange anomaly? Please e-mail
- me and I'll summarize in this newsgroup.
