Any good books on "Linux Socket prog", also on "Linux Network prog"?

Guys:

Any good books on "Linux Socket programming", also on "Linux Network
programming"?. Any valuable on-line tutorials. Appreciated.

I have never seen one, but since sockets on Linux are basically standard BSD or
Unix sockets, try searching for "Unix socket programming" or "Berkeley socket
programming".

Does "Unix socket programming" by Richard Stevens book can be used for
Linux socket programming too?.

Thanks.

Especially looking for beginner who wants to enter into Linux
programming (Network side), looking for some books which tells basics

I don't want to put a dampener on your enthusiasm, but if you are
wanting to do it properly the POSIX way, I wouldn't even consider it
unless you are comfortable programming 'C' at the level of understanding
how pointers work.

You could always consider Java - piece of cake in Java!

Is there any on-line text books available?. I did serach, but didn't
find any good ones?. Thanks.

Nope.

There are a number of really good books, and they are not cheap, but all
the POSIX sockets stuff is freely available - just download the source
code

If you are cool with this following bit of code, then you shouldn't have
a problem:

serveradd.sin_family = AF_INET;
serveradd.sin_port = htons(portnum);
memcpy(&serveradd.sin_addr,
host->h_addr_list[0],
sizeof(serveradd.sin_addr));
err = connect(mysock, (sockaddr *)
&serveradd, sizeof(serveradd));

On the other hand, if you look at this bit of code and think `WTF?',
don't even think about it!

Steve,

Great, I understand, assign portnum and open a socket. What I couldn't
able to understand is, what is the port number I have to assign. For
example, I wanted to run server on one Linux machine and client on
another machine, both are on LAN (one is 192.168.1.2 and other one is
192.168.1.3), can I use any port number? or Is there any fixed port
number. I am little bit confuse what port number I have to use?. Also
whether I have to use STREAM or DATAGRAM kind of service?.

Thanks in advance.

For a client program you typically don't assign a port. What you do is
let the system select a source address based on it's routing tables and
the host you're trying to talk to, and let it select a random
unprivileged port from the pool of available ones. Stevens covers this
in detail, it's done by using special constants for the source address
and port. The book you want is:
