Skype was a videotelephony, videoconferencing, and voice calls application that ran on various platforms including Linux. In 2010 Microsoft purchased Skype. In May 2025, they retired Skype and suggested their Skype users move to Teams. A Teams-for-Linux was provided for free. It has moved from a gui application to being a browser based app. I used Teams by entering on my Linux/Ubuntu system the address in the Firefox browser of: https://teams.live.com/v2/ With Teams videotelephony I found that, as well as a propagation delay, there was about a half second delay between the arrival of the video and the matching audio arriving. i.e. The lips were not in-sync. I looked for alternatives and wondered about Whatapp, but was told it couldn't do "share-screen", which is a feature I frequently use on Skype. I have now installed the Linux version of the free and open-source Jami software. See: https://en.wikipedia.org/wiki/Jami_(software) https://jami.net/ I initially found that it was unstable and I had to keep open a terminal window and type $ killall jami from time-to-time. However once I had the video camera resolution sorted out, and I no longer needed to be tweaking set-up parameters, it seems to be much more stable. I find communication propagation time and the video/audio sync much improved over Teams in one-to-one videotelephony. Jami has a group conferencing feature. When I set up a group conference and got someone to join, to me it seemed that my computer and router were doing all the processing and they couldn't cope. Those that joined the conference found there was an unacceptable amount of propagation delay. When Jami is launched then it places an icon in the system tray which gives the option of "Show Jami" and "Quit". Note that if you click on the Jami application screens "close" button, the screen does close but Jami continues in the background until you click on the "quit". The Jami wikipedia entry states: By adopting distributed hash table technology (as used, for instance, within the BitTorrent network), Jami creates its own network over which it can distribute directory functions, authentication, and encryption across all systems connected to it. I am interested to observe how much network traffic to and from my computer is due to Jami. In the case of the bit torrent application Transmission, you can see the bytes sent and bytes received. The Jami application does not provide this feature. Does anyone know a bash command that would continuously show the jami processes' network traffic? cheers, Ian.
