Excuse the noise, but I?ve got a fragmented recollection of a strange unit of time, and my faulty memory seems to equate this with VAX and/or VMS. My google-fu has failed me (or confirmed that this is some sort of fake memory) however I thought I?d run it past the experts in here. Does anyone know of anything strange about the unit of time, or possibly the epoch, or something else associated with time measurement (or the TOY clock or basically anything to do with time) in the DEC world? Sorry for the vagueness of the question, but hopefully someone can help :) Ian

Asymmetric connectivity in a cluster

by dwe-6006＠philtest.org

I'm not sure that asymmetric is the correct description but I can't think of a better term. I am using SIMH and I have a two node cluster (with a quorum disk) the two nodes have a common system disk. The two nodes are RODNEL (1.1) booting from SYS0 and ADV2 (1.3) booting from SYS2. Both are running DECnet Plus both are running Multinet for the IP stack. At one time there was also a node (never actually a member of the cluster called HCBVAX (1.2) it booted from SYS1 but it no longer exists. The nodes are connected over an Ethernet and the MAC addresses are the ones that I would expect AA-00-04-00-01-04 (1.1) and AA-00-04-00-03-04 (1.3) HCBVAX was AA-00-04-00-02-04 (1.2) I can login to RODNEL and "set host adv2" with no problem, I can login to ADV2 and "set host rondel" with no problem. On each of the nodes I can "show cluster" and I see what I expect to see with no errors. While logged in to RODNEL the command "moni cluster" works fine. While logged in to ADV2 the wheels seem to fall off the bus - "show cluster" is fine but "moni cluster" isn't Any help would be appreciated. This is the information that I have gathered so far (I am not happy with the forwarding address in the error message from "moni proc" on ADV2 which seems to arise from RODNEL --Dave View of Cluster from system ID 1027 node: ADV2 22-APR-2018 22:24:50 +-----------------------------+ | SYSTEMS | MEMBERS | +-------------------+---------| | NODE | SOFTWARE | STATUS | +--------+----------+---------| | ADV2 | VMS V7.3 | MEMBER | | RODNEL | VMS V7.3 | MEMBER | +-----------------------------+ ^Z $ $ moni cluster %MONITOR-I-ESTABCON, establishing connection to remote node(s)... %%%%%%%%%%% OPCOM 22-APR-2018 22:24:56.75 %%%%%%%%%%% Message from user SYSTEM on RODNEL Event: Address Unreachable PDU Discard from: Node LOCAL:.RODNEL Routing, at: 2018-04-22-23:24:56.740-04:00Iinf Discard Reason=Destination Addrs Unknown, Source Address=49::00-01:AA-00-04-00-03-04:21, Forwarding Address=49::00-01:AA-00-04-00-02-04:21 eventUid FC95D640-467B-11E8-99E1-AA0004000104 entityUid 5683CC80-467B-11E8-8004-AA0004000104 streamUid 5A113900-467B-11E8-8004-AA0004000104 Still on ADV2 - NCP is odd as well: $ mcr ncp NCP>sho exec char Node Volatile Characteristics as of 22-APR-2018 22:31:17 Executor node = 1.3 (ADV2) Identification = DECnet-OSI for OpenVMS Management version = V4.0.0 Incoming timer = 0 Outgoing timer = 0 NSP version = V4.1.0 Maximum links = 0 Delay factor = 0 Delay weight = 0 Inactivity timer = 0 Retransmit factor = 0 Routing version = V2.0.0 Type = nonrouting IV Routing timer = 0 Subaddresses = 0 Broadcast routing timer = 0 Maximum address = 0 Maximum circuits = 0 Maximum cost = 0 Maximum hops = 0 Maximum visits = 0 Maximum area = 0 Max broadcast nonrouters = 0 Max broadcast routers = 0 Maximum path splits = 0 Area maximum cost = 0 Area maximum hops = 0 Maximum buffers = 0 Segment buffer size = 0 Buffer size = 0 Pipeline quota = 0 Alias maximum links = 0 Path split policy = Normal Maximum Declared Objects = 0 NCP>show know nodes Known Node Volatile Summary as of 22-APR-2018 22:31:29 Executor node = 1.3 (ADV2) State = on Identification = DECnet-OSI for OpenVMS NCP>def node rodnel Node address (1.1-63.1023): 1.1 Node name (1-6 characters): rodnel NCP>set node rodnel all %NCP-W-UNRCMP, Unrecognized component NCP>set node rodnel Node address (1.1-63.1023): 1.1 Node name (1-6 characters): rodnel %NCP-W-UNRCMP, Unrecognized component , Node NCP>exit Whereas RODNEL seems happier: NCP>sho exec char Node Volatile Characteristics as of 22-APR-2018 20:15:29 Executor node = 1.1 (RODNEL) Identification = DECnet-OSI for OpenVMS Management version = V4.0.0 Incoming timer = 0 Outgoing timer = 0 NSP version = V4.1.0 Maximum links = 0 Delay factor = 0 Delay weight = 0 Inactivity timer = 0 Retransmit factor = 0 Routing version = V2.0.0 Type = nonrouting IV Routing timer = 0 Subaddresses = 0 Broadcast routing timer = 0 Maximum address = 0 Maximum circuits = 0 Maximum cost = 0 Maximum hops = 0 Maximum visits = 0 Maximum area = 0 Max broadcast nonrouters = 0 Max broadcast routers = 0 Maximum path splits = 0 Area maximum cost = 0 Area maximum hops = 0 Maximum buffers = 0 Segment buffer size = 0 Buffer size = 0 Pipeline quota = 0 Alias maximum links = 0 Path split policy = Normal Maximum Declared Objects = 0 NCP>sho kno node Known Node Volatile Summary as of 22-APR-2018 20:15:37 Executor node = 1.1 (RODNEL) State = on Identification = DECnet-OSI for OpenVMS Node State Active Delay Circuit Next node Links 1.3 (ADV2) 1.1 (RODNEL) NCP>sho node adv2 char Node Volatile Characteristics as of 22-APR-2018 20:16:02 Remote node = 1.3 (ADV2) Service password = 0000000000000000

Handful of points: * the idling is done by modifying the idle loop in the guest operating system to interact with the KLH10 idler device, not by identifying the idle loop like SIMH does. * until the OS is up and running, there is no idling. In other words, while at the BOOT> prompt there will be a loop consuming 100% CPU waiting for terminal input. This is normal, and it has always been that way. * if you have had the same TOPS20 system running, with idling, earlier everything points at your host os (ubuntu) no longer cooperating with KLH10. I myself run (mostly) FreeBSD, and I have never had problems with idling the TOPSxx systems. * for TOPS10, there are a couple of more things to consider, one of them is that the idler device by default is at device code 700, which can't be accessed from the mode the -10 idle code runs in. Using 740 works. I would look for what has changed in your host os (ubuntu) regarding system timers and such. Your setup *should* work. > Thanks, > Mark --Johnny

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

Time for a new release announcement of TCP/IP for RSX-11M-PLUS. This release contains a lot of fixes and improvements in many areas. There are a couple of very serious bugs in TCP that is fixed in this release which is why I really encourage people to upgrade. (They do not happen often, but if they happen, they have a high chance of crashing the system.) Highlights: - Stability and reliability improvements in TCP. - Improved HTTPD - Improved MAILD Magica.Update.UU.SE, which is a real PDP-11/70, have now run with the latest release for over 3 weeks without any issues, so I think it's safe to say that this product is now very stable. Mim.Update.UU.SE (an emulated 11/74) have in the same time served over 7Gb of data over FTP, HTTP and other lower volume channels. (And both of these machines are more or less fully exposed to the internet, so they see a *lot* of connections and random attempts to compromise them all the time.) Detailed information on things that have been done since the last release: TCP: - Improved handling of received TCP push packets. - Improved TCP ACK handling under lost packet recovery. - Improved TCP window update handling. - Bugfix for the condition that a socket was closed while there was outstanding sends and the remaining window was 0 and the transmission was not ACKed. This would cause the socket to get stuck in a pending state. - Improved TCP write handling. The second IOSB word was previously not set to reflect how much data was written. - Added new TCP option for sockets to optionally return available data at read if push was set. - Bugfix in TCP. An internal data structure was sometimes modified when it should not be, which could cause a system crash under rare circumstances. HTTPD: - Improved error handling for CGI pages. - Improved subprocess handling for CGI module. MAILD: - Improved MAILD to handle broken Linux MAIL11 server. - Improved MAILD error handling. - Bugfix in MAIL. When composing mails, the temporary file is now created under SYS$LOGIN. - Added timeouts for various parts of MAIL11 processing. Libraries: - Improved subprocess handling in BASIC+2 library. - Updated F77 library and documentation. Multinet: - Improved performance. As usual, the distribution is available from: ftp://mim.update.uu.se/bqtcp.dsk ftp://mim.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Mim, or also at http://mim.update.uu.se/tcpipdoc The firewall for Mim have now been removed, so no need for the alternate ports, but Mim is still listening to the alternate ports as well. ftp: 10021 telnet: 10023 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

KLH10 not idling host CPU

by phiber＠phiber.com

I'm posting this here in the hopes that there are other KLH10 emulator users on HECnet. I've been using KLH10 with the tap patches for years and years, and idling has always worked fine. At some point over the recent couple of years, idling stopped working for me on linux (I run ubuntu 16.04.4 LTS with latest updates as of yesterday, on a 64-bit intel machine). My CPU is stuck at 100% utilization, without even starting an emulated OS (I run TOPS-20). In fact, as soon as I type "GO" in KLH10 and before doing anything else, the CPU immediately shoots to 100%. Is anyone else seeing this? In older versions of ubuntu/linux this didn't happen. Thanks, Mark

Weird bridge problem

by sampsa＠mac.com

Hi, I?m running the bridge with the following bridge.conf: ?? SNIP --- local eth0 update psilo.update.uu.se:4711 hilanet 84.231.64.229:4711 maguro 38.130.230.105:4711 [decnet] local update hilanet maguro [lat] local update hilanet maguro ? SNIP ? But when I run the bridge using ?./bridge 4711? I keep getting these weird errors: Dumped packet from 38.130.230.105 (1024). Any ideas? Sampsa

Public Services over DECnet

by fsword007＠gmail.com

Yes I am interested in that. Let me know when done. Also you can send scanned docs to bitsavers. I put each package funetnje and hujinje into git together and uploaded it into my github account. For decent for Linux, I converted CVS repo into git repo and uploaded it into my github too. So you can now apply fixes to that repo. If you find JNet 2.x software, please let me know. There is programming guide doc in JNet package through 3.2. It was removed on 3.3 or above. No they are not in funet and can?t find them through google so far. Does anyone have JNet for Alpha? I have only JNet 3.5 to 3.7 for VAX.
