Any people here with computer networking skills?

[zerox 1,050]

just wondering if we have any networking people here.

I know the following stuff: LAN, MAN, WAN, IP, TCP/IP, HOSTS file, DNS, DHCP, FTP, SMTP, POP, ports, IMAP, IPCONFIG, PING, TRACERT, NAS, PROXY,...etc stuff that I forgot mention.

sucks for me that I always think that I don't know enough. I know people going to computer/tech universities and don't know how to clone a HDD. :/

Not much, but I do know a few things about it,

I'm actually currently on a Computer Networks and Security degree at Staffordshire University. However I'm only in my first year and I'm only really familiar with the design and configuration of networks based off of Cisco kit. Come back to me in a couple of years and maybe I'll be able to hold an actual conversation about it.

how does that look anyway?

all I had to learn computer networks was a 112 page PDF, wikipedia, google and ~1month of school. it took a lot of effort but I passed the test.

I'm not 100% sure what you mean by this. Do you want to know what Cisco kit looks like? How the topologies look, the configuration? Because whatever you learnt was likely tailored around Cisco, they have something around an 80% marketshare in computer networks. The only other networking company I'm familiar with is Juniper, and I only know of them by name, haven't gotten around to messing with their kit yet.

I'm just interested how in general does the thing look like because I never heard about it/never seen it.

[Verily British 144]

Well, there are many different pieces of Cisco kit:

You've got their Switches:

(Here we have some of their Catalyst switches)

 

You've got their routers:

Firewalls:

Layer 3 Switches:

 

You've got topologies, which I think are the same regardless of the brand you're using.

And you've got some basic configuration for some switches: (This was taken from a piece of my own case study work about a simple hospital network)

As a Computer Science major I should learn it at some point, but currently I know very little.

Oh and something interesting. some time ago a warned one of my friends that running a website and forum on port 80/HTTP is not safe as people can sniff people's usernames and passwords but he ignored that. I found it odd that he didn't care yet he made 300-500eur from adsense every month.

Interestingly enough, I know a ton about networking in general but most of my experience is with Linux and with Mikrotik devices. I've never touched a Cisco device in my life, and I never plan to if I don't absolutely have to (Don't want a job in this field, prefer it as a hobby as it is far too stressful.)

All I have work with is Javascript and Putty.
