Cisco Removed Its Seventh Backdoor Account This Year, and That’s a Good Thing
Here’s one of the several reason why you cannot rely on proprietary software: you can’t never be sure your systems don’t have a backdoor.
Note: the same holds for its main competitor Juniper.

Some months ago I’ve set up a Debian 9 virtual machine on the VMWare server of the SME I work for. I planned to enable several services on it:
I picked Debian 9 as the operative system as it allows for a leaner and lighter installation when you start from its netinstall version. Knowing that the 40Gb I provisioned for 4 users will surely require to be expanded sometime in the future I used Logical Volume Manager.
Everything looked fine and ran smoothly for some weeks then I started to find the machine hanged.
As I’m the only full-time employee with some proficiency in IT I am the de-facto help desk for anything “computer related”: remote banking issues, updating Java on Windows 10, maintaining installed the latest Firefox version that still support the Java Applets required by the remote banking, handling anti-viruses, non-administrative applications updates and so on. All this listing to say that I have root access on the VMWare console. I needed to reset this VM (called posta)
I had to Disable screen blanking on text console (thanks, Stack Exchange!) to catch the bug as I just can’t stare at a console for several hours hoping to catch it. So, after having removed the timeouts I left the console opened for a while.
I hadn’t to wait too long. The day after I’ve finally got a clue to follow :
Finally something to look for: the bug is in the kernel driver vmxnet3_rq_rx_complete. Luckily it seems a fairly common bug; excluding the bug reports from RedHat that are – rightly so! – available only to the subscribers of their services there is an interesting bug report in VMWare Knoledge Base titled «Linux VM fails with the error “kernel BUG at drivers/net/vmxnet3/vmxnet3_drv.c:1413!” (2151480)».
As the VMWare also runs the main administrative applications I think it wasn’t worth a call to the remote management so I’ve applied the workaround on posta.
As this bug showed somehow randomly I can only leave the console open and keep an eye on it.
I’ll let you know if it worked.

Fira code is not the only programmers font. Its web page also lists:
they are all free-as-in-freedom. Personally I prefer Fira
