Ruby Socket to Java Socket
Hello ! I have some problem trying to establish dialog between a Ruby socket(client) and a Java server socket (java.net.ServerSocket). Everytime I try to write on the server socket I get an "Invalid stream header" error from the server... s = TCPSocket.open("host", 9061) s.write("test \n"); => Error Can someone give a little hint on how to start inthe right way on this ? Thx a lot ! Seurdge -- Posted via http://www.ruby-forum.com/. Ok, I have experiment a lot and found that : When the Java Server use : in = requestSocket.getInputStream(); It wo...

C socket to Ruby socket
Hello What is the correct way to convert a C socket (int) to a Ruby Socket object in a C extension? Something like int s = socket(...); VALUE sock = rb_some_func(s); In my extension there's a callback function that receives a socket as an argument, and I'd like to pass that socket as an argument to a ruby block, so I need to convert it to a Socket object first.

socket.sendall(), non-blocking sockets, and multi-threaded socket sending
My application requires sending a large piece (~2MB) of data to several devices on a network via TCP sockets. I have experimented with different methods for doing this and this has raised some questions about the implementation of Python sockets. (both methods use blocking sockets) Method 1: Calls socket.sendall(data) for each device in sequence, all in a single thread. Method 2: Each socket has its own thread that calls socket.send(datachunk) iteratively until all data is sent. So Method 1 sends all data to device1, then send all data to device2, etc... until all data is sent to all devic...

socket/sendmsg seems to drop packets socket/sendmsg seems to drop packets socket/sendmsg seems to drop packets socket/sendmsg seems to drop packets socket/sendmsg seems to drop packets... how to
Hi, I am using the function sendmsg to send for example 1000 packets over a socket from one computer to another. The function call always succeedes, i.e., -1 is never returned. However, when using tcpdump on the sending computer, I see that only 984 out of 1000 packets are actually sent out from the computer (I see the same 984 packets with tcpdump on the receiving computer). How should I debug this to see where the 16 packets are dropped? It seems as if they are dropped somewhere in the Linux kernel.

Socket#gets and Socket#puts
We really ought to think about documenting the Socket class tree. :) Okay, I'm learning with a little "Trial by Fire" over here. I'm building a threaded server. I'm using Socket#gets for reading and that's going fine. I've learned that it returns nil, when the connection is closed. Does it throw exceptions under any conditions and if so, which ones? What about Socket#puts? If it's waiting to send something, what happens if the connection is closed? Should I expect any exceptions on this end of the equation? Thanks. James Edward Gray II On ...

Socket operation on non-socket
Sometimes I get an error message when I try to check my mail that says "Socket operation on non-socket." Can anyone tell me what could be causing it? Thanks, Cliff Lewis Your email server was too busy to respond within the alloted time out. It happens sometimes when the server is too busy. If you try again it probably works?

Uncatchable socket.error in socket.py (?)
Hi, I've written a very simple 'kill-server' to help me shut down processes through Telnet or HTTP. The kill-server is a function and is launched as a thread. I use the module socket.py on Python v2.3 (Windows) I can use telnet host:port and enter the secret killword or use a broser with http://host:port/secret_killword The 'kill-server' validates the secret_killword and writes a file to /tmp. The main process regularly checks for the existence of that file, and ends the loop if it does exist. It works well. But most for the fun (because this will probably never be ex...

Reconnect socket without close/socket?
I am writing a program that needs to read some data from a server via a TCP socket every few seconds. (The server is the hddtemp program, running in daemon mode.) Documentation is somewhat sparse, but AFAICT the server simply accepts connections, writes its output to the socket, and immediately closes it. So every time I want to poll the server, I need to reconnect. Is there any way to accomplish this without doing a close()/socket() cycle every time? I've tried using shutdown(fd, SHUT_RDWR), but I get a "Transport endpoint is already connected" error. Thanks! ...

Socket 478 to Socket 775 adapter?

With Intel now not producing the 478 anymore, if I wanted to upgrade the chip to a higher speed such that there was not any 478's produced at that speed, I am looking at buying a new MoBo which is a definate no at the moment with my system just having a new board in it (ASUS P4S800).

Why bother? recv will return EBADF if the descriptor is invalid anyway. However you are correct - using fstat you can check the st_mode field for the file type.

Socket programming: Command and Data socket
Hi all, I am learning about socket programming from the books from Richard Stevens. I just started, but browsing thru the books I didn't find an example of how one could implement a program that uses two sockets for communication (like for example the FTP command, which uses a data and a command socket). I am trying to write such a program myself, but I can't really get around the design of the program. My questions is relatively simple (I think). How would I go about setting up communication with two sockets? I just need ideas on how to do this. I've been trying to get this work...
