In perl socket programming how to send a data from client and receive it from server.

Perl Socket Programming What is Socket Programming? A socket is a procedure which helps to establish a virtual connection between different processes over a network. A computer receives and sends information by the various applications running on it. This information is routed to the system by a unique IP address assigned to it.

Perl Socket Programming Examples It's always a pleasure to run private courses - for when a questions that's a little bit away from the normal comes up, I can take time to provide a full answer and demonstration without fear of loosing delegates from other companies who have no interest. Basically a socket is a mechanism of creating a virtual duplex connection between the different processes. Using socket programming with perl, a typical computer system on a network receives and sends the information as desired by the various applications that are running on it. makes the socket non-blocking, but a friend of mine just laughed and said that I'm wrong He said that I better use Fcntl, but it still could be done with IO::Socket... I'm confused. Let's say according to me, a non-blocking socket allows other parts of the code to be executed in the same time where the socket is being read or wrote.

Perl sockets work like file handles that can span across a network or the entire Internet. Some would make the case that Perl is the most used and most capable scripting language on the Internet today, and this is probably true.

The first, master, holds all the socket descriptors that are currently connected, as well as the socket descriptor that is listening for new connections. The reason we have the master set is that select() actually changes the set you pass into it to reflect which sockets are ready to read.

Re: Network Programming With Perl example 1 by jasonk (Parson) on May 01, 2005 at 17:55 UTC In addition to the good suggestions everyone else gave you, it's also entirely likely that this problem has nothing to do with the fact that you are running it on windows, and everything to do with the location of the windows server you are running it on. Sockets are a software methodology to connect different processes (programs) on the same computer or on different computers. The name "socket" reminds us that once we "plug in" one process into another process's socket, they can talk to each other by reading and writing the socket. Sockets are a huge and diverse subject.

For this we use the Perl select function, which sets the file handle to use for standard output. Note in Listing 2 that the socket file handle is selected; then the special variable $| is set to 1 to force a buffer flush after every write; then STDOUT is re-selected. Now our client can send a request to the server.
