You sometimes want to check if a program that you've installed is doing anything funky. While you could install a full-blown packet analyser like WIreshark, sometimes, that is overkill. A quicker and handier option would be to just rely on good old netstat. Like so:
netstat -bn 10
as well as
netstat -bf 10
-b: displays the program name (executable)
-n: displays the IP address
-f: displays the resolved form of the IP address
This is how you can send a message from the commandline using the mailx (mailutils) package.
Adapting a solution for switching windows between displays in XFCE / Xubuntu 20.04
The command to use is route. Use route --help and route print for information and then use the following command to change the gateway from 192.168.0.1 to 192.168.1.1.
route change 0.0.0.0 MASK 0.0.0.0 192.168.1.1
Good luck :)
So, I've been facing some DNS issues with my Ubuntu box and needed to do some debugging. While I was certain that my router was assigning the Google DNS servers (8.8.8.8 and 8.8.4.4) via DHCP to my machine, I needed to make sure that they were actually being used. Usually, I would be able to tell by looking at the output of /etc/resolv.conf oslt. However what I found in resolv.conf was
So I have a Xubuntu box, an old PC that was running Windows previously. All is peachy with the Linux install bar one thing: every time I shutdown the system, it shuts down fine, but immediately restarts again. This wasn't happening with Windows and appeared to be an issue particular to Linux or Ubuntu.
Freeplane, a fork of the mind-mapping program, Freemind, works really well. Except for the fact that in my (K)Ubuntu installation, it sometimes hangs in the middle of editing a node. Once it becomes non-responsive, the only fix is to kill the process and restart the program. The version of Freeplane in Ubuntu 18.04 is 1.6.13. However, the current version (March 2019) of Freeplane is 1.7.7. So, it's highly possible that upgrading Freeplane to the latest version will fix this issue.
So I have a couple of routers connected to my network each linking to a different ISP. When an ISP goes down, I want to easily switch ISPs from the command line and these are the couple of lines I use to do so:
Today, I started dabbling in doing some screen recording in Linux and while I could find programs to record the screen, I couldn't get the audio working as I wanted. By default, the programs record either the system audio, or the mic audio (or if the program is shit, neither); they don't record both the system audio and the mic audio. The fix for this on my Kubuntu 16.04 (Xenial) system which uses the Pulseaudio system to manage audio is as follows:
