zabbix on Windows: check the configuration before restarting the Zabbix Agent service

Posted by jpluimers on 2019/09/27

If the Zabbix configuration on Windows (especially mismatches in C:\zabbix\zabbix.agentd.conf.d), then the Zabbix Agent will not start at all:

C:\zabbix\bin\win64>zabbix_agentd.exe --start
zabbix_agentd.exe [4711]: ERROR: cannot start service [Zabbix Agent]: [0x0000041D] The service did not respond to the start or control request in a timely fashion.

This is how to check it before starting the service:

C:\zabbix\bin\win64\zabbix_agentd.exe --config C:\zabbix_agentd.conf
zabbix_agentd.exe [43]: ERROR: cannot add user parameter "MyDuplicate[*],PowerShell.exe -File C:\zabbix\UniquePowerShellScript.ps1 "$1"": key "MyDuplicate" already exists

The problem is that in the C:\zabbix\zabbix.agent.conf.d directory, two files had a similar config:

UserParameter=MyDuplicate[*],PowerShell.exe -File C:\zabbix\FirstPowerShellScript.ps1 "$1"
UserParameter=MyDuplicate[*],PowerShell.exe -File C:\zabbix\SecondPowerShellScript.ps1 "$1"

The problem is that the first part of UserParameter (before the [*])  is a key which needs to be unique over all configuration files.

If everything is fine, you will see this:

C:\zabbix\bin\win64\zabbix_agentd.exe --config C:\zabbix_agentd.conf
zabbix_agentd.exe [1581]: use foreground option to run Zabbix agent as console application

If you need to manually start Zabbix as a service, then perform this (the first step is not needed if the service has already been stopped):

C:\zabbix\bin\win64>zabbix_agentd.exe --stop
zabbix_agentd.exe [1642]: service [Zabbix Agent] stopped successfully

C:\zabbix\bin\win64>zabbix_agentd.exe --start
zabbix_agentd.exe [1642]: service [Zabbix Agent] started successfully

Skin effect – Wikipedia

Posted by jpluimers on 2019/09/23

Skin effect – Wikipedia:

Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductorsuch that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor. …

At high frequencies the skin depth becomes much smaller. … Because the interior of a large conductor carries so little of the current, tubular conductors such as pipe can be used to save weight and cost.

Outlook 2013 cannot logon to gmail any more

Posted by jpluimers on 2019/09/20

A problem on a PC I did not use often: as of a sudden, Outlook 2013 could not access a gmail account any more.

Luckily, Outlook showed me this message in a dialog box:

Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)

This directed me to [WayBack] Use IMAP to check Gmail on other email clients – Gmail Help

In turn that pointed to [WayBack] Let less secure apps access your account – Google Account Help

Finally that one indicated the configuration page changed to https://myaccount.google.com/lesssecureapps

This is similar to the cause of “the user name or password for imap.gmail is incorrect” – iPad, iPod or iPhone with iOS < 7

It all comes down to gmail forcing OAUTH2: [WayBack] tls – Why doesn’t outlook 2013 meet modern security standards? – Information Security Stack Exchange

Dieser Artikel beschreibt, wie man einen eigenen Mechanismus für DNS-Updates als DynDNS-Alternative aufbaut.

This article describes how you can create your own mechanism for DNS-updates as alternative for DynDNS.

The above post disappeared, but this one (which adds calling the DynDNS server from a Fritz!Box) is still up: [WayBack] Eigener DynDNS mit Bind, Apache und PHP | onderka.com with an update at [WayBack] Eigener DynDNS mit dnsmasq, Apache und PHP | onderka.com.

Blast from the TomsHardware past – Stress Test: Power Supplies Under Full Load

Posted by jpluimers on 2019/09/16

Blast form the past, as I just found out I had archived the (moved) pages where the original link wasn’t:

We put PC power supplies from 300 to 850 watts under continuous load to see if they can satisfy the power appetite of potent Athlon and P4 systems. Are they efficient and stable? Click into the THG Laboratory to find out!

Sources: the “Stress Test: Power Supplies Under Full Load” series:

The original page was not archived (likely because they dislike WayBack), but linked from [WayBack] Using PC power supplies in things other than PCs which I linked to in Convert/adapt an old ATX Power Supply into a Bench Power Supply with (or without) 3D Printed Parts

Note that [Archive.is] Data Collection And Live Upload refers to the – now gone – Inadequate and Deceptive Product Labeling : Comparison of 21 Power Supplies , which I found back as well:

In spite of the high end-user retail prices, our lab technicians were surprised by the test results. No fewer than 6 power supplies struggled under full load: 3 of the candidates simply went up in smoke, while the other 3 shut down prematurely. The “black sheep” among all the test participants was Maxtron, with the TOP-520P4. According to the manufacturer’s specifications, this power supply is represented to be capable of withstanding 520 watts – divided up over the corresponding voltage ranges. However, in our test, it ceased working at 446 watts. Completely dead!
