=> ↺ Maybe we shouldn't default to allowing logins on machines
For this reason and others, we have been slowly making more and more servers be 'staff only' servers, where all non-staff logins get rewritten to have a 'you can't log in to this server' shell. At this point we have more staff-only servers than unrestricted servers, although an unrestricted server is still the default. Given how pervasive this restriction has become in our environment, quite possibly it should become the default, and the few unrestricted machines be specifically set up for that.
=> ↺ Testing iperf through an SSH tunnel
So in my case, I wanted to run iperf through an SSH tunnel. This isn't ideal, because you're testing the TCP performance through an encrypted connection. But in this case both the server and my computer are extremely new/fast, so I'm not too worried about the overhead lost to the connection encryption, and my main goal was to get a performance baseline.

We should all be doing these. Backing up ensures that if something happens to your virtual machine(s), you have a second unaffected copy that you can restore.
=> ↺ LFCS #2: How to Install and Use Vi/Vim as a Full Text Editor in Linux
A couple of months ago, the Linux Foundation launched the LFCS (Linux Foundation Certified Sysadmin) certification in order to help individuals from all over the world to verify they are capable of doing basic to intermediate system administration tasks on Linux systems.
The Linux administration tasks involve first-hand troubleshooting and maintenance, plus intelligent decision-making to know when it’s time to raise issues to upper support teams.
