why shutdown report error?

view story
linux-howto

http://stackoverflow.com – on Linux I tried the steps below: create TCP socket, and connect to any HTTP server send HTTP request data shutdown write with SHUT_WR read from socket to get the HTTP response shutdown read with SHUT_RD close the socket here error occurred in step 5, with errno=ENOTCONN. The same error hit me when I tried shutdown Write after reading EOF. Is this expected? (HowTos)

Stories similar to why shutdown report error?

Consider a TCP connection is established between two TCP endpoints and one of them invokes either:

close(): Here, no further read or write is permitted. shutdown(fd, SHUT_WR): This converts full duplex connection to simplex where the endpoint invoking SHUT_WR can still read.

However, in both the cases FIN is sent on the wire to the peer endpoint.

I'm trying to create a client socket to send a http request to a server, but an error is occurring in the function connect, in turn primeir returned this error: "connect: Socket operating on non-socket 'and' connect: no such file or directory 'I did not find anything wrong in my code so I went looking two examples of client sockets, and they tanbem returned this error.

my code is this:

Hello

I am trying to communicate with a server that is ready to accept HTTP GET requests and send back data per the request. However, I have very little experience in socket programming and I don't really know how to debug this. Googling on the web hasn't yielded much, except people saying I need to read the HTTP 1.1 spec which is the last thing I want to do.

I have web server with OS RHEL 6.2 and Mysql 5.5.23 on another server and the web server can read from Mysql server without problem, but some time I got this error:

[Sun Sep 23 06:13:07 2012] [error] [client XXXXX] DBI connect('XXXX:192.168.1.2:3306','XXX',...) failed: Can't create TCP/IP socket (24) at /var/www/html/file.pm line 199.

my question :

What does this error mean (Can't create TCP/IP

Shutdown problem 49 weeks 18 hours ago

Hi, I'm using Mythbuntu 12.04 (although I had the same issue with 11.10 which is why I did a fresh install of 12.04 with db export/import). I have set it up with mythwelcome to shutdown when idle and start up for recordings according to:

http://http://www.mythtv.org/wiki/ACPI_Wakeup

For the most part it all works well. However, occassionally the system hangs when shutting down.

I have written below multi-threaded TCP client which basically spawns a separate thread for receiving the data however the data is being written in the main thread only having taken input from the user on standard input.

Now, having pressed ctrl^D then implementation comes out of the loop (around the getline () call) and closes the socket descriptor but no FIN is seen on the wire.

I have a server that receives a continuous stream of data. As opposed to reading multiple times from a socket, I would like to read the entire data in socket receive buffer with one system call to read().

Of course I can pass a large buffer and read() will try to fill it with all available data.

I'm struggling here...

I'm trying to determine if data was successfully sent to the server through a TCP socket using the OutputStream object. For testing on emulator socket communications is loss after 30 sec. For write data OutputStream.write(); its doesn't throw an exception , and local server continuously running its not crashing, only tcp socket connection is loss after some time.

How are you, good afternoon, I do not speak and I do not write in English, and I'm iniciandome in unix / linux on my own, I am using the google translator, my question is this, know what are the shutdown command to change user State:

# shutdown -y -g0 -i0 (completely off my system) # shutdown -y -i1 (switch to single-user state) but when I switch to another state like 2 or 3 or 4 or 5 can not
