The most important part of Linux user interaction is the console. Met here with a wonderful script to check the speed of the Internet connection.
All you need is to go to the project page and perform a couple of simple operations, I did not use the most affordable many options.
curl -Lo speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
chmod +x speedtest-cli
or
wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
chmod +x speedtest-cli
With these commands we will download the script and allow its execution. Additional flags to run in the sequel.
If you need to see SIP messages coming from the peer, and what messages your server sends to it, then on the server you need to run the following command: "asterisk -rx "sip set debug peer SIPuserID"" SIPuserID, respectively, change the name of the SIP user account. It is important to take into account that the Asterisk server must know the user's IP, in other words, the user must be registered or have an IP registered in its settings.
Actually for the last 2 days this program for an exchange of messages on the PC at me fell not less than one hundred times. I use it intensively, there are too many contacts there, of course I would like to switch to an alternative, but so far it is impossible. If you also often closes WhatsApp like me, then look how to overcome the constant restart and sudden shutdown. To be fair, the developers do not declare support for windows 7, but thank God do not prevent the use of its program on this operating system. Update from 2019-01-28.
Something recently often, there are questions in the style of "I'm lost", "loading with a temporary profile" and then decided to keep at hand a solution to the problem. And so the system is loaded with a temporary profile, because when you load with a local profile, it does not work. This is not the worst option, it happens worse when the profile does not load or immediately gives an error. I hope you have at least 2 profiles on the computer Administrator and your account. Because:
"You are logged in with a temporary profile" - this means that all if, make changes to the registry with a temporary profile is possible, but to fix the problem you will need a different account. Run the administrator account that generates the errors. It is for such situations, I have a separate account of the administrator is always there, which I advise you.
Then write what needs to be done.
