I am not going to bore you with old Linux one-liner jokes that you might have come across several times already. It’s 2021 and we still don’t have a decent compilation of new funny Linux jokes.
So, I took some time and searched on various social media platforms for some really witty Linux humor.
If you are an intermediate to experienced Linux user with some knowledge of networking, you’ll have no difficulties in understanding the jokes at all. If you are a sysadmin, even better. I am not a sysadmin but I studied in-depth about computer networking during my masters, so it was easy to grasp the underlying fun.
Don’t worry, if you are a novice to Linux or have no previous knowledge of networking protocols, I have included some hints to the jokes here. I know that the best jokes are the one that need no explanation, but when geek humor is involved, a little explanation doesn’t harm. I mean, that’s the reason why there is a website dedicated for explaining xkcd geek jokes.

Explanation
- When there is a change in DNS, it needs to be propagated to all other servers. This process takes up to 24 hours in completion.
- IP addresses are scarce. NAT (Network Address Translation) protocol is the way in which all devices connected to the router have private IP address while the router is connected to the real networked world. Ducks are supposed to be sound like nat-nat.
- UDP (User Datagram Protocol) is a networking protocol which doesn´t guarantee the delivery of data packets. Normally, we use TCP protocol to communicate with the internet. UDP is mostly used in real-time systems.
- Open a terminal and use the command ¨ping www.google.com¨. You´ll understand the joke.
- There are limited number of IP addresses available in IPv4. With the rapid expansion of the internet, IP addresses have been exhausted. Read this for more info.
- CIDR was introduced to mitigate the IPv4 exhaustion.
- Read this to know about how SYN flood is used for DDoS attacks.
- Read this to know about Foo bar.
- In RAID, an additional parity bit is added to detect error. If this parity bit is off (i.e. 0), it indicates an error.
- Every networking devices, your smart phone, computer etc, has a MAC address that is often represented in hexadecimal format and looks like 01:23:45:67:89:ab. These MAC address are used to determine which device would receive the data packet.
MAC address FF:FF:FF:FF:FF:FF is used for broadcasting the data packet to all the devices. This FF:FF:FF:FF:FF:FF is also called big MAC in networking world. - Self explanatory
