Ok, put the following on your router: access-list 1 permit 216.15.64.181 snmp-server community <community name> rw 1 Choose an unused access-list of course. :) This will allow only me to access your read/write snmp community. Give me the community string you've used. I'll add it to the db and everytime a new config is generated it'll autoload that on your router. Keep in mind that I'm not doing a 'wr mem'/'copy run start' yet as I haven't quite figured that one out yet so if you reload your router you'll lose the latest version uploaded. -brian

Cisco Tunnel Config

by wonko＠4amlunch.net

Ok, more progress being made. Now when a row gets updated a trigger function is set off which auto-generated the new configs. Once happened last night, but I didn't have it passing info through so I had no idea what caused it. I can guess that it was Cory's IP changing because the only cron-ed task right now is to check and update dynamic IPs. That caused me to re-write the db trigger that handles catching the updates to pass info through the payload function of LISTEN/NOTIFY. It now also auto-matically loads the config on my router so as soon as something is updated mine router is good to go. Anyone else who wants this to happen please let me know and please make sure bart.4amlunch.net has access to a RW snmp community on your router and I'll have it load the new configs on the fly for you. -brian

Download a PDP-11 w/o Ethernet?

Kind of like doing MOP over Ethernet, but without the Ethernet. Yes. Exactly what interfaces is something I'd need to check up, though.

Cisco Config Tool Update

by ian＠platinum.net

Florian, Thank you for this list - very helpful. The problem I now see is that I don't have enough RAM - I only appear to have 32Mb and all of these images want 64Mb. In the morning, I'll try some of the images in the emulator - if they have the features I need, then I will go ahead and get a RAM upgrade for the router. Thanks again.

Download a PDP-11 w/o Ethernet?

by Paul_Koning＠Dell.com

Others already answered the boot ROM part. As for the protocol, MOP arrived first on DDCMP, and yes, that includes load/dump. If anything, it's primarily load/dump. The Sysid stuff is specific to Ethernet. I think DDCMP MOP also has MOP level loopback, using MOP packets which are different from the 90-00 Ethernet loop protocol. In DDCMP, MOP is a mode ("maintenance mode") -- same basic frame format but it's a datagram service as opposed to a connection oriented service. It's all spelled out in the specs ("maintop" which is MOP, and the DDCMP spec). paul On Feb 4, 2013, at 5:49 PM, Bob Armstrong wrote: An off the wall question that I m sure somebody on HECnet will know was it ever possible to download a boot image (e.g. RSX-11S) to a PDP11 over a DDCMP serial interface (e.g. a DUP/DMR/DMC or whatever)?

It was fine until the VM host moved to vmware... I have three news for you: 1: It's a known bug (good) 2: It has a workaround (good) 3: You won't like it (baad!) The bug is related with the async timer implementation in KLH10. It has been discussed in the TOPS-20 mailing list and someone (IIRC was the late Mark Crispin himself) said it was not fixable. The relevant details (and the workaround) are here: Ahh. I wonder why the bug just suddenly appeared for me... https://groups.google.com/forum/?hl=en&fromgroups=#!msg/alt.sys.pdp10/xndbq… Now the bad news. The KLH10 idling "device" is based on the asynch timer implementation, and DOES NOT WORK with synch timers. That means KLH10 will use all your available CPU, all the time. There is ANOTHER workaroud for that (I'm using it with my KHL10 simulator running in a rasp-pi). If you are going to use Linux search for a nifty utility called cpulimit. It does just what you think it does :). In a crude way, but it works. Hmm. I think I might look in to that, thanks!

Are these ROMs for an M9312 boot/terminator? They weren't on the DMC/DUP card? Correct, they appear to be M9312 ROMs. De
