Multi-Client TCP Server with pthreads Mutex Synchronized - Code-walk of viewer code - Sekhar Pariga ↗
Saturday' 26-Sep-2020
Here is a code-walk of a git-hub source submitted by a viewer Sekhar Pariga, which is a Multi-client TCP Server with pthreads Mutex synchronized. Basically it is a Directory Listing Server, that serves ls, cd, pwd of directory functions to connecting TCP clients which are remotely (locally) executed by the server. Server is implemented using multi-thread pthread library, to serve multiple clients simultaneously. Server keeps the each accepted client session details in the queue data structure. Client session queue contains each clients socket-fd and present working directory as a queue node.

Adding your own Kernel Modules into Linux Kernel Source | Linux Kernel Programming ↗
Saturday' 26-Sep-2020
Whenever you do custom kernel modules, you can optionally make it a part of existing Linux Kernel source. This does not mean you are submitting your kernel module to the mainline kernel source (i.e kernel.org Linux Kernel Foundation). What I meant is, you can make your kernel module(s) part of Linux Kernel source so that when you compile your kernel you can automatically compile your kernel module(s) too. As well when you create/modify kernel .config configuration file (such as via make menuconfig, etc), you can enable or disable your kernel module(s) too.
To do the same you have to register (and include) your custom Kernel Module's Kconfig and Makefile to the existing Kconfig and Makefile of the Linux Kernel source Here is a detailed multi-episode video of mine which gives the overall idea and the big-picture.

Roadmap - How to become Linux Kernel Developer - Device Drivers Programmer and a Systems Software Expert ↗
Saturday' 26-Sep-2020
Many viewers and even sometimes my students ask me how I can become a kernel programmer or just device driver developer and so on. So I shot this video (and an add-on video) where I summarized steps and a roadmap to become a full-fledged Linux Kernel Developer.

IP-in-IP Tunneling Demystified - VPN Tunnels ↗
Saturday' 26-Sep-2020
There can be many ways one can architect VPN Networks. The end objective is to tunnel private IP (typically LAN subnets) within public IP Networks (such as Internet). You can establish such a tunnel in various creative ways, such as Transport Mode, Tunnel Mode, IP-in-IP tunneling, etc. Also you can choose any transport layer protocol of your choice such as send VPN traffic via TCP, or via UDP and so on.
