Apart from this, there have been the usual bogus users that have been removed last month, I’ll clean the wiki cache so I get rid of these disabled accounts.

Disk full
Before I was able to check the results of the montly maintenance job yesterday – done remotely this time – I found out the system didn’t respond at all. I could acess the router and that showed me a number of connections on the different ports, but hardly any traffic. I could start a VPN session to the home network, but all I could do was ping. No other access was possible. Would it again be a problem with the quorum disk, that I had some weeks ago – no way to tell….
This evening, it turned out there was nothing worng with the quorum disk, but the DecWindows sessions that I have opened didn’t show up after I switched on the monitor. I would expect the unlock panel top show up, but it was just the background of the window and the system was not responsive at all.
After having started my other node in the cluster, it happily joined the cluster, and there seemed nothing wrong with the disks. Bot any of them. Now I tried to mount the system disk of the main system – but that failed. Not any disk could be mounted….So the systen ran, but was unable to react.
Not even CTRL-P on the console…So the only option was to use the reset button.
Next, I rebooted. The process continues as usual – until, in the end, the main part is started in batch.
Now the real issue was obvious: the queue manager couldn’t start because free space was exhausted.
The procedure ended normally, but again, the system did not respond to teh keyboard, but now I knew what caused the problem.
So I started the system in MIN mode, but once mre, I couldn’t enter the system because it didn’t respond to the keyboard….
The last resort: Start from CD, choose option 8 to do some DCL, Mounted the system disk to find out what caused it. It must have been files created since yesterday after 18:00 system time, so
$ DIR/SIN=yes/SIZE/unit=byte DKB100:[...]
woud show what caused it.
BINGO. Almost immediately.

Cleaning up
I removed all ‘new users’ in this blog where I suspect them to be bogus; there has been two spam attempts using comment blocks, but comments are to be approved first, so these have never made it to being published 
And since I’ve been messing around with MoinMoin, there have been no more abuse attempts there either; no more new ‘users’ have been signalled.

Quite a lot of “job offers” in the last weeks. Most quarantained, some discarded, and what’s over 200 points is simply rejected. The number of relay attempts has not changed a lot…
What’s more irritating are the bogus wiki “users”: posting spam, almost every day I find a few new “users” and some do post some linking page. Inappropiate to the contents…Some seem to think they can do similar on this blog, but I wonder what they think they can do. No-one writes a post or page, but me

The usual maintenance
Now in time 
.
There is nothing in particular to mention, just that the number of relay attempts has decreased to a minimum, there hasn’t been a logfile over 4 blocks in size – there were just a few that exceed zero blocks.

It might be worthwhile to have a closer look over past months – but the internal statistics show the same level of decrease.
The only thing that is annoying at the moment are the bogus users created on the VMSwiki that create spam entries. There may be one of two at some days, requiering me to take action: disable all notifications, shut down the account permanently, and removeing spam. It takes just a few minutes, so it’s not a big issue – at least, for now.
What’s more: JeanFrançois Piéronne has released Pothon 2.7.2 on VMS, including MoinMoin 1.9. It’s time to update! Same applies to PHP – Mark Berryman has done 5.3, and WordPress should be upgraded as well….but that requires a re-thinking of the mapping…I’ve neem busy with that – but seem to have lost the workinmg example and so I;ll have to redo it all. What a luck I’m using WASD, because of the Watch utility!

Maintenance – at last
Once again, it has taken quite some time to do the monthly maintenance. That is: checking whether the batch job has done it’s work. Well, it seems. I got the mail stats for September:
PMAS statistics for September
Total messages : 979 = 100.0 o/o
DNS Blacklisted : 340 = 34.7 o/o (Files: 30)
Relay attempts : 34 = 3.4 o/o (Files: 30)

Rejected : 148 = 24.4 o/o (processed), 15.1 o/o (all)

Discarded : 75 = 12.3 o/o (processed), 7.6 o/o (all)
Quarantained : 150 = 24.7 o/o (processed), 15.3 o/o (all)
Delivered : 41 = 6.7 o/o (processed), 4.1 o/o (all)
A significant decrease of spam. I’ve observed this in the last month anyway. But still, it’s still a low percentage of valid mail….Moreover, the number of relay attempts have dropped to a low level. Could that be related to the fact I moved to another ISP?
Next, I need to install a number of updates, the last I made was about a year ago. So at the moment the system disk is being backed up, and after that, I’ll do the updates. They may require more time than I have available, it could well be I’ll have to wait until tomorrow to get them installed….These were all updates released until February this year, so I’ll have to get the next ones as well. There has been some trouble (again) with SAID’s but it should now be solved.
I’ll notice in a while

Maintenance
This month’s maintenance-run yieled no problems – except that the next morning, there was a list of logfiles but none was available for review. A known issue – matter of wrong order, unless I decide to keep the files available for a few more days. Anyway – I got the mail stats:

The vast majority of relay attemps have been on then 18th and 19th, in a somewhat lesser extent there have been attemps on the 8th and 27th, and even less (but still substantial) on the 25th.
