Socket Error 13 Description


See also readBufferSize() and read(). [virtual] bool QAbstractSocket::setSocketDescriptor(qintptr socketDescriptor, SocketState socketState = ConnectedState, OpenMode openMode = ReadWrite) Initializes QAbstractSocket with the native socket descriptor socketDescriptor. Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. Why are my prints low quality when screenshotting a PDF? See also socketDescriptor(). [protected] void QAbstractSocket::setSocketError(SocketError socketError) Sets the type of error that last occurred to socketError. weblink

Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP. See also setProxy(), QNetworkProxy, and QNetworkProxyFactory. [signal] void QAbstractSocket::proxyAuthenticationRequired(const QNetworkProxy &proxy, QAuthenticator *authenticator) This signal can be emitted when a proxy that requires authentication is used. They signal unusual error conditions for which there's no WinSock error equivalent. Examples shown are compiled using the GNU C++ compiler on Linux: Basic steps in using a socket: Socket include files: Include FileDescription sys/types.hTypes used in sys/socket.h and netinet/in.h netinet/in.hInternet domain address http://stackoverflow.com/questions/24001147/python-bind-socket-error-errno-13-permission-denied

Socket.error Errno 13 Permission Denied Port 80

This reset could be generated locally by the network system when it detects a connection failure, or it might be received from the remote host (in TCP terms, the remote host The default value for this idle period is 2 hours. Functionless Errors There are a total of fifty unique WinSock error values. See "Tips and Best Practices" below.

  1. If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet
  2. try to ping the server(s)).
  3. We took the text of the errno manual page in BSD 4.3, filled in gaps and embellished, completing the information.
  4. Is it good to call someone "Nerd"?
  5. The Nagios log shows the following after a fresh reboot but nothing if I try to run that command manually. [1371152186] ndomod: NDOMOD 1.5.2 (06-08-2012) Copyright (c) 2009 Nagios Core Development
  6. A reasonable value is 10.

This book is a must for any serious UNIX/Linux programmer. This means that you must: Send fixed message sizes of a known number of bytes where all messages sent are of the same size or Send a message with a header File: serverFork.cpp #include #include #include #include #include #include #include #include #include #include #include #include #define MAXHOSTNAME 256 using namespace Socket Error 10054 WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error.

QAbstractSocket::HostLookupState1The socket is performing a host name lookup. Return Getattr(self._sock,name)(*args) Socket.error: [errno 13] Permission Denied WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available"). In this case, the 2nd application will fail with WSAEADDRINUSE. why not try these out waitForDisconnected() blocks until the connection has closed.

Also see the connect man page The sockaddr_in data structure: /usr/include/linux/in.h /* Internet address. */ struct in_addr { __u32 s_addr; /* Defined as 32 or 64 bit address (system dependent) */ Tcp Socket Error Codes Socket BSD API man pages: Sockets API: socket: establish socket interface gethostname: obtain hostname of system gethostbyname: returns a structure of type hostent for the given host name bind: bind a Does a natural 20 on an animal handling check do anything special? The specified socket parameter refers to a file, not a socket.

Socket Error Codes Linux Developer suggestion: are you trying to use an optional feature?

For instance, even if you request to send() a few bytes of data on a newly created TCP connection, send() could fail with WSAEWOULDBLOCK (if, say, the network system has a have a peek at these guys The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections. When this signal is emitted, the socket may not be ready for a reconnect attempt. No more file handles are available, so no more files can be opened. What Is A Socket Error

If the signal handler performs a normal return, the interrupted function call will seem to have returned the error condition. Setting the SO_REUSEADDR option explicitly allows a process to bind a port in the TIME_WAIT state. Looking at netstat, I see this: unix 2 [ ACC ] STREAM LISTENING 841374 /var/run/saslauthd/mux unix 2 [ ACC ] STREAM LISTENING 840356 @/com/ubuntu/upstart unix 2 [ ] DGRAM 840610 @/org/kernel/udev/udevd check over here WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links.

No data verification. Python Socket Error Errno 98 Address Already In Use As you can see from the comprehensive list of WinSock functions, this error is the catch-all. Berkeley description: Normally results from an attempt to create a socket with an address not on this machine.

Close the socket when done: TCP/UDP #include ...

WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported. Typically their descriptions are similar. The function will timeout after msecs milliseconds; the default timeout is 30000 milliseconds. Socket Error 10049 WinSock functions: getpeername(), recv(), recvfrom(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAENOTEMPTY (10066) Directory not empty.

a "high-level" protocol). C++ Get min / max value of a static array at compile time How could a language that uses a single word extremely often sustain itself? If not, check with your WinSock vendor to see if they have a newer WinSock available. this content you didn't call setsockopt(SO_BROADCAST)).

Note that the above compile/link commands apply to Linux (and Cygwin which includes socket and network libraries in cygwinl.dll). timeToWait.tv_sec = 0; timeToWait.tv_usec = _lWaitTimeMicroseconds; FD_ZERO(&readSetOfSockets); FD_SET(_socketHandle, &readSetOfSockets); if(_socketHandle > fd_max) { fd_max = _socketHandle; } iSelectReturn = select(fd_max + 1, &readSetOfSockets, (fd_set*) 0, (fd_set*) 0, &timeToWait); // iSelectReturn -1: When it occurs, it could indicate a serious failure of your network system (i.e. The server application might need to call htons() to translate the port to network byte order in the sockaddr structure.
