FYI - Guys, I'm back from the desert, areas 8 and 47 are alive again...

by sampsa＠mac.com

Just thought I'd let you know that CHIMPY:: and HILANT:: are finally back up again, had some hardware trouble with my hosting box, but was stuck in the Sinai desert... All is well now, and CHIMPY, GORVAX and HILANT are back online.. sampsa

Network change stuff

by b4＠gewt.net

Hello all, Hey Brian...in the next week or so I'll be simplifying the tunnel and moving to a (mostly) static IP through cable. I will also be replacing the current DECnet router (a Cisco 2524) with a much more recent 1841 running IOS 15.1. ;) Maybe tftp will work now? ;););) -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Adjacencies Keep Bouncing

by robert.jarratt＠ntlworld.com

Ah, the changes once per second would explain those sequences one second apart coming from 8.400. I had not noticed that in the specs. I guess those updates could be coming because 8.400 is not seeing some packets (or they are being delayed), so it is changing its mind about the liveness of some adjacencies and so sending out updates. My router does not send updates as they change, it waits for the hello timer. As for my pacing of the Level 1 Router updates, the spec does anticipate some issues because it wants you to stagger the starting point (para 6 of section 4.8.1). My pacing should not affect other nodes, the problem seems to occur when I *send* a lot of packets all at once, it seems to affect the receive side. If other nodes send me lots of updates in a burst, that seems to be OK.

In the extract above it is repeated 3 times, then 3 times, then 5 times. The rule is that router hellos are sent every hello time, or whenever the content of the message changes (different DR, different router list, change in router priority, etc.). Hellos sent when a change occurs are limited to one per second. 3. For a node to decide to drop an adjacency (ie to exclude it from the Ethernet Router Hello message), it must fail to see an Ethernet Router Hello for 3xHello Timer (Hello Timer is 15 seconds by default, so 45 seconds).

If this was UDP dropping packets, then I would have hoped that it would not drop my particular ones 3 times in a row over a period of 45 seconds. So, somehow, my Ethernet Router Hello messages are being dropped on their way to 8.400. However, this can t be outbound from 5.1023, because if that was the case then all my adjacencies would all go down at the same time. At any one time, only adjacency goes down. This suggests that the packet is somehow getting lost towards the end of its journey to 8.400. What kind of node is 8.400? 47.556 is another one that appears to have this problem, I see that one is SIMH. I am wondering if pcap/winpcap might be implicated here. The reason is that I noticed winpcap seems to drop incoming packets if you have sent a burst of outbound packets. In my router I was sending all the DECnet Level 1 Routing messages, all at the same time and getting some problems similar to this with a node local to my network, because my router did not see the packets coming from the other node, even though the sniffer could see them. I changed my router code to send the Level 1 Routing messages with a 1-second delay between them, and that problem went away. So, I am wondering if the remote nodes I have this problem with are SIMH nodes? Yikes. DECnet assumes that data links don t have defects like that. If you need a workaround like that, chances are things won t work anyway, because the nodes you re talking to will not do packet pacing like that. paul

Quick cluster question

by Dave＠TheLennons.Net

Cory, If you want to share the SYSUAF.DAT (and you technically don't have to in a VMS cluster, but it gets a bit hairy with multiple ones), you would put it on a common disk directly mounted by all nodes and pointed to by the SYSUAF system logical name, oh and usually a bunch of other files are included with this, There is a template command procedure in SYS$STARTUP that describes them, I believe SYLOGICALS. A quorum disk is only needed to provide a vote, and usually only used in a two node cluster. Recent VMS versions do have external authentication capabilities but you still have a SYSUAF.DAT as a backup... - Dave On 6/12/2014 5:40 PM, Cory Smelosky wrote: Got a (hopefully) quick question regarding clustering I've got a VAX<---->Alpha cluster rolling (VAX for booting VAX satellites, Alpha for Alpha satellites) and I'm running in to an issue with the SYS$UAF stuff. Only the password/user DB...nothing else needs shared. What's the easiest way to share it between the VAX and Alpha nodes WITHOUT a using a quorum disk? 1). Kerberos or something? (I could have both query active directory...) 2). Shove SYS$UAF on MOIRA$dka100, mount in SYLOGICALS on all nodes? 3). Other
