With my connection, I noticed that the circuit would disconnect and reconnect periodically. It corresponded to the timeout in my firewall causing the UDP association to be lost. When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable. Unfortunately, my firewall (a SonicWALL NSA 240) is also stupid in that it *must* randomize the source port for outgoing packets, so I'm not able to connect to HECnet because MultiNet insists that the source port must also be 700 and mine are coming through with random port numbers. --Marc

HP Integrity

by md.benson＠gmail.com

If anyone has a HP Integrity zx6000, rx2600 or a similar machine that takes DDR2100 Registered ECC RAM I have 2x spare pairs of 2GB RAM sticks available pulled fresh working from my zx6000. I also have a 1.3GHz/3MB cache CPU module that I might be persuaded to part with. This is more an FYI than a 'I must get rid of these for cash now' - I figured a few people were running Integrity machines and might want he parts. I took mine down to 1 CPU and 8GB of RAM to cut down the power consumption and heat output (it's down from 480W to 200W at idle now :) ). Now to install VMS 8.4 on it! -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.

I see these message about every 20 minutes from random nodes. The error message is almost always: "Unexpected packet type" So where do we go from here? -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Saturday, June 09, 2012 01:15 To: hecnet at Update.UU.SE Subject: Re: [HECnet] netowrk flapping....

LAT works fine in TOPS-20. In TOPS-10 LCP tells me LAT is active, but it does not work (does not even announce itself). How do I enable LAT in TOPS-10? Don't knew. 3) And, spealking of LAT... How do I change the service identification in TOPS-20? What do you mean with service identification? The stuff in "sh exec char?" I mean, how do I change it PERMANENTLY? I guess I have to put it in some sort of auto-executing file. SYSTEM.CMD? Something in 7-1-CONFIG.CMD? Again, any pointer to docs would be very appreciated. I don't want to bug you with the thousands of questions I've got :) Right There is nothing permanent, unless you poke it in to the monitr.exe file....

I've got a rack of DSSI drives (RF7x and RF3x) that'd love to have a little tape drive for a cousin :-) I too would like to find any TF or RF drives, also would like to find a KFQSA so I can try out my KA655 CPUs.

I don't know how much truth there might be to it, but I have been trying to find a TF drive for a long time, they just don't seem to come up. Are they as rare as they seem? I didn't think they were all that rare, but now that you mention it, I have seen many more TK50s and TK70s than Tx85 drives. Not sure why. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
