Uptime Robot SMTP check is not service-specific (yet) but a TCP check…

Posted by jpluimers on 2018/04/11

When you use the check on the SMTP port, note that [WayBack] Uptime Robot on Twitter: “Yes, it is not service-specific (yet) but a TCP check.… “.

It does to full DNS protocol checks from IP address though, so I am glad about that.

via: [WayBack] Jeroen Pluimers on Twitter”@uptimerobot I have the impression that the SMTP port check does not really check anything but the port being open. Had a flaky mail server that would react on the TCP level, but timed out on the SMTP level. Uptimerobot did not notice that.”

Posted by jpluimers on 2018/04/11

So we are all doomed: on debian, beep was an issue leading into a CVE. The fix is an issue too, and also has a CVE.

CLIFF Electronic Components – Quicktest; Resistance wheel

Posted by jpluimers on 2018/04/11

[WayBackCLIFF Electronic Components – Quicktest:

The Quicktest is ideal for electrical shops, factories, labs and service departments.

With its lid open the wires of a plugless lead can be inserted into the insulated clips. When the lid is closed, current passes to the equipment being demonstrated or tested.

A neon light shows that the connector is live and ready to use. The fuse (BS 1362) is easily accessible for replacement.

The connector is made of tough, safe materials. The base is phenolic moulded for insulation and rigidity. The lid is flame retardant glass filled thermo plastic.

The insulated clips are colour coded for easy identification. The flexible cable grip will take any normal mains cable. Only one small screwdriver is needed for both the base entry and the terminal screws.

Another handy tool is this: [WayBackResistance Wheel | Jaycar Electronics, but it’s hard to get so you can build similar devices yourself with a few hours of work:
