News from the Blog 2021-05-22

  • The company has provided me and the members of my Team with unlimited Cloud capacity for testing and developing. That’s very nice. I plan to run some nice workloads to asses the performance of several solutions.
  • I’ve had tons of assignments from the university and with the classes to my students I had no much time.
  • The Health Department and the universities (CIT and UCC) offered free PCR for the students. I can only say Kudos again for Ireland.
  • They also offered certain more vulnerable students to vaccinate with Pfizer. More Kudos.
  • I bought some cases for Raspberry Pi 4.
  • I’ve bought a Wi-fi Mesh TP-Link to repeat the Wifi signal to zones of the house it was arriving weak. I’m very satisfied with this signal repeater.

This little buddy also provides an Ethernet to connect to a laptop or to a switch.

So far I have only tested with a laptop and works great.

  • I’ve written one article about the GUI Software I use on Linux Desktops.
  • I wrote another article about cloning applications you’ve working in other Linux Desktops under Wine.
  • I also released CTOP TAG v.0.8.4 and fixed some bugs in upcoming CTOP v.0.8.5 and added a new feature to display the File Descriptors in use and the Max FDs set in the Kernel. This feature needed some work as I did calculating all the FDs per process but Kernel has another value that comes from /proc/sys/fs/file-nr so I finally implemented this last value, fixed a bug in conversion of units with decimals (KBs without the decimal part) and added Unit Testing to check this cases. I was satisfied to release v. 0.8.5.

Fixing Wifi not enabled in Linux Kali with Dell XPS laptop

This is a trick I share, as I see many students having problems with this.

Assuming that your Kali distribution is recent (Linux Kernel bigger than Kernel 5.3), the most typical problem student have is that laptops xps from Dell and other brands have a combination of keys to enable or disable the Wifi.

On the Dell xps is on the key PrtScr, so if your Wifi is disabled, you can enable it in Kali Linux press:

CTRL + ALT + Fn + PrtScr

As you can see in the PrtScr the is an icon of Wifi Signal.

The Fn key is on the bottom left, next to Ctrl.

This is a very simple to fix problem, but many people suffer this problem and go crazy trying to update drivers or even having to use an external USB dongle.
