Where'd you learn networking?

HarmonyHarmony Member

Where did you guys learn networking? Looking for some good online courses for L3 and some basics L2 networking enough for what you would need to know to get some colocation hosting setup.

Seen some courses on Udemy but looking for suggestions

    Not too much expert in networking, but can handle my hosting problems myself. learned from Google, YouTube.

  • I think the best way is learning by tinkering with an application or necessity you have in mind.
    Like hosting a Mastodon instance etc.

    Networking is actually a fairly large subcategory of IT.

    I'm not sure anyone really know all or most of it. For example its both physical and software based. There is the pratical implementations of standards, the people who develop the standards and the manufacture of hardware.

    For example how many of us have laid fiber? How many of us can name different standards of fiber connectors without googling it? Then there is stuff like DNS which I still have trouble understanding sometimes even though I use it every day. How many of us ever looked into the source code for BIND?

    There are all kinds of specific network programs that were in use for decades that we should be aware of.

    This hasn't even mentioned telephony which many of us will never touch. What about satellite?

    With that being said CCNA is probably one of the best places to start. Then keep learning and specializing in more areas.

    Also there's a PHD Asian dude that's bound to appear on this thread soon talking about pushups I bet.

    I'm not really looking to learn everything from scratch I don't see the point in learning the base layer of networking I will only ever be operating routers/switches at a colo provider. Anything else the DC handles.

    mentally strong people learn networking by laying fibers in the mud.

    ...or by plugging and unplugging RJ45 connectors to Ethernet socket until you feel the "tick" sound by your soul while simultaneously hitting on F5 to refresh LET.

    That’s not ”networking” that’s ”net works, king”

    Edit: also a lot of networking and web security research was done in the name of winning arguments with other 14-year-olds on neopets
