Exclamation Network commands?


I believe this belongs in here (newbie) and not in Networking.

I'm completely starting out with networking. I have done some research, but I never ran networking commands in a serious way.

Is there an all purpose beginner guide to getting around a network, and learning basic troubleshooting skills? I'm using Ubuntu 14.04 in VirtualBox running on Windows 7 Professional.

I would like to get an understanding of statistics, how to map out my home network and networks I connect to and so on. So I'm interested in any help, any tips and etc.

Thanks!

It would help if you stated what exactly you want to do. But you can start here:
http://www.tldp.org/HOWTO/HOWTO-INDEX/networking.html

Some basic commands you may want to look into (using the man pages)
ifconfig
ifup
ifdown

A nice package for network analysis is nmap (can do port scans etc. in your network environment).
You probably need to install it with

Code:
sudo apt-get install nmap

Man pages are not the easiest things to read, man man gives something of an explaination.
Note that static addressing is different than that supplied by nat addressing so what appears to the outside world is different to that which appears to be your 'gateway' as defined by netsat -r.
what happens within your 'home' network is much more easy to work out and based on the 'inet addr:' details given by ifconfig.

Have fun.

Fred.

I suggest Cisco Networing CNAA (title is something like that). This a set of vdeo lectures. What is network, what is OSI, how tcp/ip protocol works, where are they come from these strange numbers 192.168.0.1, and finally how to create your own network - home or small bussines. In short. It is pleasure to watch - each lecture last 40 min. and well, there is no that strange feeling that all this is too much difficult to understand - so it must be for superhuman beings. And you can watch doing other things. Don't ask me where to get this. On this you are on your own.

CBTNuggets has a good series on this too... although not "free" like:
http://www.openculture.com/freeonlinecourses
http://www.extension.harvard.edu/ope...ing-initiative
http://ocw.mit.edu/index.htm
http://oyc.yale.edu/
...etc., or, a little less deep?: http://www.google.com/cse?cx=0176442...ork&gsc.page=1

Graphical network simulator that allows simulation of complex networks
GNS3 is a graphical network simulator that allows simulation of complex
networks.

To allow complete simulations, GNS3 is strongly linked with :

* Dynamips, the core program that allows Cisco IOS emulation.
* Dynagen, a text-based front-end for Dynamips.
* Pemu, a Cisco PIX firewall emulator based on Qemu.

GNS3 is an excellent complementary tool to real labs for Cisco network
engineers, administrators and people wanting to pass certifications such as
CCNA, CCNP, CCIP or CCIE.

It can also be used to experiment features of Cisco IOS or to check
configurations that need to be deployed later on real routers.
