Hi Everyone, What are the best resources to learn Linux for networking. Anything will work - books, tutorials, videos. Where should one start considering one is having CCNA level knowledge.

P.S Also do share some of the advantages in learning linux. where in the production world can we use linux Thanks.

A web search fo "networking linux" will turn up many helpful articles and links.

I would suggest you research some of them. When you have done some basic research, we will be quite happy to help you with more specific questions.

I do commend this site to your attention. Despite its HTML v. 3.x look, it is without question the best thing I've ever read about how subnetting works.

Linux can be used literally anywhere in the production world. Quite possibly your needs are already met or figured out by someone with similar usage.
One of its biggest advantages aside from $ cost (free) is the flexibility to tailor things to fit your desires and needs instead of being locked into what the other guy thinks will work best for you (and charges $ for).
There are a very few situations where I still need a windows machine because specialized apps only work on windows, but those are niche situations and over 99% of everything I need is done on Linux.

I'd think that the subject of networking is more important. You learn processes and then you can apply to any OS.

Probably also need to be a little clearer on what "Linux for networking" actually means. When I think of "networking", I think routers, switches, firewalls. Personally in my home set up, I buy commercial network equipment because it is specifically designed for the purpose of networking and is easy to set up. You can probably roll your own but I have no clue how to do this, other than maybe for a firewall, plus I am lazy and don't want to put in the time - I want it to just work.

In industry, in my experience anyway, networking equipment is all 100% commercial (Cisco, Fortinet, etc) and 0% open source. Servers, yes for Linux, but I have personally never seen it in networking equipment like routers, etc. That's my experience though, I am sure others have different experiences.

Look up the likes of OpenWRT, DD-WRT or Tomato. These are Linux distros for routers. And not just hobby systems; at least DD-WRT is found in commercial products as well.

I have used all three of those on home routers. I guess I’ve never seen them in commercial use like in a big enterprise. I probably have limited exposure though since my last contracting gig was with the government. They only buy big commercial vendor equipment.

The big hardware could be mostly dedicated real hardware devices that use their own ios as opposed to a purely software solution. Most of the tasks that are used will be familiar to any good networking tech I'd think.
