Any Good TCP/IP Book Out There?

[Paralyse]

does anyone know of a good programing book for tcp/ip, lang c++. i have a basic understanding for the osi model along with c++ in gerneral. is there a good step by step, a book that will hold my hand, through the process of writing programs that use tcp/ip? i'm looking to writing my own program that will ping address, or string of address. i've made my own program that will create a batch file, that when run, will ping a string of ip address, that creates a *.txt file on the results. very tedious looking throught the txt file to see which hosts are alive. i will post my source code for further understanding.

in no way do i entend to use my knowledge, or any knowledge gained, for malicous intent.

Paralyse, other members may help you better than I do.

I have one comment tho... While SOMETIMES it is really necessary to use goto to simplify the code and/or to speed up the runtime process, I don't see goto is needed here. It even (I think) complicates your code.

Try using if ... else ... blocks. I see you have used while, that's good. Then you can use system() to execute ping.exe directly. Have fun!

Peace always,

thank you for your comments and insight. i used the goto command becuase i wanted to have all the error messages all together. i guess i'm lazy. maybe i'll tweek it when i get a good tcp/ip book, if anyone knows of one

[harbir]

do u need the book for Network Programmig?

[harbir]

this is considered to be a good book for Unix network programming, i personnaly have not started reading it, but will start soon.

Author Stevens, W. Richard.
Title : UNIX network programming / W. Richard Stevens, Bill Fenner, Andrew M. Rudoff.
Imprint : Boston, MA : Addison-Wesley, c2004
i hope this helps u mate, if u need more information let me know we can search it out.

Hands down the best book about TCP/IP is TCP/IP Illustrated by W. Richard Stevens.

I can recommend all three volumes. The last volume is more programmers based and talks about ways to setup services and using the protocols in C.
