New versions of Mosquitto and Paho installed
I got new versions of Mosquitte and Paho, aside a number of exampled files in Fortran and Cobol, to work on for the fecility I’m working on. I installed them more compressed than before, but there are some things missing – I may have to install one more package that uses MQTT for communication as well: RabbitMQ. Samples.com had to be redone because there are new files in this pack, but as I found out, the library misses a number of routines that are referenced – or seem to be referenced.

Certificates updated
The renewal of the site certificates by the WCME-overseer has been completed successfully – and the transfer to the correct position has also been done. Though the email message was sent before the certificate files have been moved to the right position, and been loaded.
www.grootersnet.nl however is still a problem – still have to drill down why, but it is less of a concern for the moment.
MQTT developments
Tested the samples, using the MQTT dashboard app on my (Android) mobile phone. It took some time after checking what the examples used for naming both sender and receiver. but in the end I got my two connectors: One subscriber and one publisher. With this configuration, I could run both directions.
There are two flavors: synchronous and asynchronous.
Asynchronous works in both directions: Published a message on the VMS system, it was received by the app; Publishing in the app is received on the VMS box.
Synchronous however shows a problem: a message published on the VMS box will be received by the app, but the subscriber on VMS will never show a message published in the app: My guess is that the callback function is never triggered.
To find out, I built the subscriber program with debug, but couldn’t start it in debug mode – since it needs to be started as a foreign command ($ Sub :== $stdoutsub, and start it with $ sub MQTT*) it will not start the debugger – I forgot how to get it in the debugger….($ run stdoutsub works, starts in the DBG> prompt, but the program will request parameters – you cannot pass this way).
Ok: asked Brett Cameron for some hints .
Will now first create code so I can publish (and subscribe) from other programs – if Brett hasn’t created them already.

Worpress update
First action today was an update of WordPress, top version 4.2.9. I could of course do the normal stuff first, but since the EU regulation of data protection has been activated on may 25th, and being an EU citizen, I may be obliged to be compliant and tell you (no matter where you reside) what I do with your data, and why, and – more or less – how. Rest assured: I never have, and never will, share data with others except there is a suspicion of abuse, or an official, legal request to hand over your data – no matter what. Anyway, I changed the page that WordPress hands over as a default.
That is: for this blog, to begin with. The other ones will have a similar page. Since it’s in the database, I will have to copy the contents – or I create one in a generic place and refer to that one.
Maintenance.
Well, the normal stuff. No surprises, as you may expect.

It is just on 12-May-2018 that there have bee relay attempts from an address hosted by Hostwind.com (23.254.215.49), between
12-MAY-2018 03:10:05.60 and 03:13:08.59 (193 attempts), sending for a bogus user on my domain, to a gmail account that has bee attempted several times before (1029mandaditos@gmail.com). Of course Hostwinds.com has (again) be notified and the network will be blocked (I think it already was – but it may be made a mistake there).
However, there is another problem arising I cannot handle: mail sent using my email address (faked) as sender or as reply-to address. At times I receice messages from postmasters from everywhere in the world that a message cannot be delivered because the recipient does not exist, mailbox is fuill or whatever reason there may be. Luckily I have an easy proof that such a message cannot be sent by me; this page Is still valid.
Signalling on smartphone/font>
Something I am thinking of for quite some time: Signalling of whatever is needed, on my smartphone – and, if possible, a (limited) set of commandprocedures I can start from the same device. Started this – I have Mosquitto (MQTT broker) running on Daphne, and code to send (and receive) messages: thinks to Brett Cameron. I wonder if he took his sources from GitHub – I got them from there – so I’ll ask him if there is any change I should incorporate; but since this one works, I can start with this version. Hopefully i’ll be noted earlier of relay attempts so I can notify Hostwinds at that very moment…
Database problems – again
It has bee quite on this for a while, but I’m plagues with “Connection lost” errors at this moment – each time I edited this page, the connection to the database is lost – and reconnection seems to be failing…
