It was necessary to monitor once at one of the stations with servers when power supply disappears. At the station, the UPS was installed, and there was a generator in front of them, which turned on automatically when there was no power supply, so there were cases when the generator could not start, and the UPS was discharged and everything turned off.Continue reading “I connect sensors to UniPing v3”

Once a friend from Ukraine asked me to help her with the closing of the account in the Polish bank Pecao.
She was not going to go to Poland and therefore could not visit the bank, so I started correspondence with employees by email, which was specified in the contract, and also is on the official website.
In the first message, I asked how you can close the bank account and the employee replied that you need to visit the bank for this, but you can also write a written request and send it along with the bank card by the postal service to the bank branch where the account was opened.
I will share information on this issue that has arisen from me.
I noticed recently on one of the computers that the mail stopped loading in Mozilla Thunderbird and the following message was displayed:
The IMAP server “…” does not support the selected authentication method. Please change the “Authentication Method” in “Account Settings | Server Settings”.
Before that, the mail was successfully downloaded, nothing changed in the Thunderbird configuration and on the mail server.
On a neighboring computer with similar parameters, there was no problem.
As I found out, the problem was in ESET NOD32 Internet Security and after turning off its protection (not a firewall) – the problem disappeared.
It’s amazing that the problem did not appear right away, during mail setup for example.
Since this computer was changing hardware and reinstalling the OS, and also mistakenly installed ESET NOD32 Internet Security, I did not investigate the reason for the blockage, deleted it and installed ESET NOD32 Antivirus, which was always on this computer, with the hope to continue to investigate the problem if it repeats itself, but after that it disappeared and did not appear.
