I want to know more (about... networking)

Hail, how are you gentlemen ?

I am looking for someone who will point me to a guide or whatever will help me understand somethings about networking, etc, for example:

1- What does this mean ""It doesn't seem a good idea to me to share your drives on your ISP's network. You mentioned you have your PC's connected with a second NIC, I suggest you only enable file-sharing on this NIC and not on the one that's connected to the internet." (http://www.antionline.com/showthread...0&pagenumber=1)

2- Whats the difrence with the cable connection ? it seems like i have a network with the rest of the people wich use my provider ?

3- I also want to learn about ip things, i know there are some that start xxx.xxx and you can see that they are local\internet\network, whatever... i need to learn the basic

4- Also about ports... i dont much about

5- How does sharing work... if i share a folder will i share it to my network, to my provider, to all the internet ? i would like to know how computers set this to work.

I know they are basic questions... but i need to start somewhere, anyone cares to tell me where to find info ? i also have other questions, that will come later, for exemple about equipment those things that give internet access to 2 computers (router or whatever) how would the ips work, would each computer have his own ?

I know im messed with this post because it isn't intressing, etc... but well i need info, maybe someone cares :) i know i shoul search this forum and the internet for this info, but with this post i can get a link to the good place and not get bad information.
Thanks

Farewell

If this comes across as flippant, then my apologies in advance, as it is not intended. You are a student-yes? I do not know what you are studying, but if is not a computing discipline, the I would suggest that you change your course of direction, as everything you want to know cannot be learned and fully undestood in a short space of time. there is masses of information on this site alone covering what you want to know to say nothing of the resources on the www. in general. If you arer really that interested then I would seriously look at your educational options

hello there,

I think you should have posted this to the networking forum.

Thank you.

Cheers

1) Number one is a bit hazy to me, but the best I can explain it, don't let the computer thats directly connected to the internet have file sharing options turned on, but rather just the second computer that your networked with (which is what the NIC card is used for)

2) The difference between cable and what...you didn't give anything to compare it with.

3) IP Tutorial A nice simple site that teaches you the basics of an IP

4) Ports are basically like holes in your computer that a program needs to go through in order to access the internet, with a firewall, you can filter whether or not the program can go through to hole. A nice list of ports can be found Here

5) Sharing works by having your Share files and folders option turned on, depending on your OS this option can be found in different places, from what I know you just share your temporary folders, so if you want to share anything else you would just put it in your Temp folder. You do share it to all the internet unless you password protect the files.

If I've been mis-clear anywhere, just say so and I'll try to clarify myself. Hope this helped.

[edit] heh I took so long writing this I see everyone else has got here before me [/edit]

umm.. well I don't know if it's me or what but I can't follow the link you've posted. Before I go any further

consider revising this attitude a little - yes we do care and yes a lot of folks are willing to help, but we aren't really into doing ALL of your spadework for you!

ok to make a start on this
1) having not read the thread (see above) I'm not entirely sure of the contect this was said in. However I would infer that the computer in question is connected to a cable modem and a LAN (or at least on a peer to peer with another computer) and that it has 2 NIC's (network interface card). Ok one of the purposes of a LAN is to share resources (e.g. hard drive space, printers, files, programs etc), so assuming that you want to have a useful LAN then you want to enable file and printer sharing on the NIC connected to your LAN (commonly goes thru ports 137- 139 and one other I can't remember - 445??) - I'm assuming you know how to do that - if you don't some more info as to what OS your using would be helpful (I'm guessing Windows of some form?). However you don't want to be sharing your resources with everyone else do you (do you??) - so you do not want file and printer sharing enabled on the NIC which your cable modem is attached to - if it is then you're sharing your files with everyone else who gets hold of your IP address. If those files include sensitive or private information (credit card number, bank statement, love letter to girlfriend etc) then you want to keep them to your self - i.e. turn off file and printer sharingon the NIC attached to your cable modem. If you don't know how to do that just say and someone here (including myself) can tell you what to do (or you can look on the net don't forget). At this point if you don't already have a firewall on your system - I'd REALLY look into getting one - especially as you seem to be using a cable modem.
2.Difference with a cable connection - as opposed to a connection with what??? If you have a cable modem then yes you are technically part of a large network it's normally referred to as the Internet and yes you will be sharing that 'network' with other people on your ISP (this is the reason you don't want file and printer sharing on the NIC attached to the cable modem) Maybe this question is bound up in the earlier thread but like I say I can't read that at the moment.
3. Basically an IP address is like a postal address for your computer.. it can be 'static' (as your postal address is) or it can be 'dynamic' i.e. changes everytime you connect to your ISP (probably not like your postal address unless you move around a lot). This link
http://www.wikipedia.org/wiki/IP_address
might be of interest to you if you just want basic info. If you want to know more then take a look at O'Reilly's books on IP, TCP and Networking (http://www.oreilly.com/).
4. Port can be quite a nice drink on a autumnal evening :-) .... seriously a port is like a door to your computer - data passes through it. Again a quick search on the wikipedia will give you the following basic info
http://www.wikipedia.org/wiki/Port_(computing)
5.If you share a folder.... well you share it to everyone who is able to log on to your computer over a network... it's up to you to decide who to share it with (at least nominally - I'm not going to talk about illegal accessing etc). Normally you'd want to share a folder to your network i.e. your LAN and no one else (this goes back to the first question)... you do not want to be sharing your files to your ISP or the rest of the internet... incidentally in case you use P2P sharing programs then you are sharing your resources with the rest of the world... that's why things like Kazza are a breeding ground fro virus, trojans and every other piece of malicious s**t under the sun.

Well theres some basics (and I know the answers are basic) but really... you can find this info out from anywhere on the net or by purchasing a few decent books (like I say look at O'Reillys website cos they produce some of the best books in the world IMHO). Have a look around first.

Hehe of course i don't study computers, i had to make a option, or i would be even more nerdish and geek and study computers, and at this time i would already know lots of things, the other option was stop to make more things about computers, what i mean, i already wasted all my day in front of a computer, should even work more and study computers ? or should i do something else, now i study the opposite hehe.

I did waste lots of time i had to read and learn about security.

Thanks zonewalker!

1- Damn dude you write too much, you just had to read the post wich i linked, arghhh didn't work, sorry! http://www.antionline.com/showthread...hreadid=244120
I really wanted to know about this, because now each time i want to access the other computer, i have to share and then unshare... is there any way that i can leave it ALWAYS shared and only with the network ?

2- People say that there is something special about a cable connection, because it is like a "network" and not directly to a terminal or whatever.

3- Hehe i know that about ip address, what i wanted to know is for example people say xxx.xxx are for network, etc etc etc... thats the kind of thing i would like to understand

Sorry i really see that i can't get all this info and learn, i also have lots of questions about proxys, etc about how all this works.
Tell me what can somone who doesn't study computers and lives in a town where there are no real computer meetings to explain things do ? i found it hard to start understanding this things.

Ok I'll try and keep this short then :D

1. disable netBIOS over TCP/IP (file and printer sharing) on ANY connection to the internet, enable netBIOS on the connections to your LAN. If you are still using Win98 then this page might interest you;
http://grc.com/su-bondage.htm
Once you have disabled netBIOS on ALL internet connections then you can simply go into windows explorer and map a drive to the shared resources on your LAN - make sure you tick the 'reconnect at logon' boxes this will allow you to keep sharing your drives over your LAN but not over the internet (assuming you follow the instructions on Gibson's Bondage page properly!)
2. Cable connections are always on connections to the internet via your ISP - essentially what you have done with a cable connection is hooked yourself up to a large network (i.e. a wide area network [WAN] - as opposed to LAN - local area network). But there's nothing 'special' as such - it doesn't work any differently from a LAN
3. I don't understand what you are interested in. Are you talking about class A/B/C network designations?? Could you be a bit more specific?

If you don't have any local user groups around and you really are on your own then really your only options are to search the internet, buy some books and come to places like AO.

Like I said earlier a book from O'Reilly would be your best bet... either use the link I gave you before or search on amazon. For a beginners guide to LAN's you might want to have a look here
