We support some legacy PHP code for several clients. Because of this, we have been strongly suggesting that they upgrade their code to PHP 7.3 so they can get off of older PHP 5.6 (and some even older – yikes!) servers.
I currently help support several CentOS 7 servers for various clients. I admit that I am not a Linux guru by any stretch. But I can setup a server, install Apache, PHP and MariaDB, install SSL certs, update firewall rules, etc. Basic server needs.
Today, I needed to see what the downstream was like for a server I help maintain. Usually in Windows I would go to SpeedTest.net and see what it was, but this isn’t going to easily work on a CentOS server. What to do?
Today I had a 13 MB WSDL file that I had to diagnose what HTTP(S) calls were made by the service. Because the file was so large, it made it difficult. Grep to the rescue!
