TCP/IP tutorials/resources?

[Larkfellow]

I'm wondering what type of resources (maybe libs?) come with Linux (specificly RH6.1 and Helix Gnome) for TPC/IP programming. Maybe even something with a tutorial/examples with it? I'm just looking for more basic stuff right now, something like, oh lets say a mail client. Thanks for any info you can provide.

You probably want to learn about sockets first. Search around this forum for sockets stuff and there is PLENTY. Internet sockets are what C uses to establish TCP streams from one host to another, so you'll need to learn that first. In fact, start simpler - try a simple chat client or echo server or something like that.

Yes, I realized later, after looking at another post on sockets, that is what I need to start with. And I did get that one page that was referanced as a tutorial on another post.
And as for something "simple" I had been under the impression that a mail client was one of the more simpler ones of TCP/IP... and since you mentioned it anyways, what exactly is an echo server? heh. But thanks for the suggestions.

An echo server is pretty much what it sounds like. It sits and accepts connections and then sends back everything it gets sent to it. So, if I were to connect to an echo server and type "hello", I would get a "hello" back.

A mail client can't be any easier than that http://www.linuxnewbie.org/ubb/smile.gif Besides, if you want to create a mail client that actually complies with Internet standards, you have to create one that will do either POP3 or IMAP or SMTP protocols, I believe. Not sure, though, as I've never bothered to create one.

I plan to work on socket programming myself and found a book at the bookstore Linux Socket Programming by Example. The publisher is Que. I had a chance to browse it and it seems to be pretty good. Hell its the only book of its kind for linux that I know of.

finally, after weeks of waiting for someone to return it, my university library got Unix Network Programming vol 1by Richard Stevens. read chapter one tonight and i dig it so far.

starts off very simple and seems to progress to much more complicated stuff. as a matter of fact, the first socket created was almost as easy a the echo, it was a time-of-day client.

from what ive seen and heard about Richard Stevens' books, i would highly recommend any of them. http://www.linuxnewbie.org/ubb/biggrin.gif

Yeah, "Unix network programming" is the only networking book you'll _ever_ need...

His other book TCP/IP Illustrated is also a *very* good book. I would recommend any of Richard Steven's books, they are truly good books. Steven was one my favorite Technical authors.

See I have a problem with getting books as there are no good book stores around here. And the university library is pretty empty when it comes to tech. books like that. And I don't to the on-line shopping thing. In fact I don't do the credit card thing. Anywho... I'll see what I can manage for now.
