sin_addr is the IP address in the socket (the socket structure also contains other data, such as a port). The type of sin_addr is a union, so it can be accessed in three different ways : as s_un_b (four 1-byte integers), s_un_w (two 2-bytes integers) or as s_addr (one 4-bytes integer). inet_addr converts an IPv4 … Read more
This usually means that there was a network error, such as a TCP timeout. I would start by placing a sniffer (wireshark) on the connection to see if you can see any problems. If there is a TCP error, you should be able to see it. Also, you can check your router logs, if this … Read more
You have two options: Use Cygwin (Unix emulation library). Port to Winsock (Windows standard library). Cygwin: lets you compile your Unix sources mostly untouched, but ties you to the Cygwin emulation library. This have two implications: general performance -no only network- will probably be less than optimal; and the target environment must have (at run … Read more
This error can occur when the local network system aborts a connection, such as when WinSock closes an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket). See this MSDN article. See also Some information about ‘Software caused connection abort’.
I’m looking at functions such as connect() and bind() in C sockets and notice that they take a pointer to a sockaddr struct. I’ve been reading and to make your application AF-Independent, it is useful to use the sockaddr_storage struct pointer and cast it to a sockaddr pointer because of all the extra space it … Read more
So I am working on an iPhone app that requires a socket to handle multiple clients for online gaming. I have tried Twisted, and with much effort, I have failed to get a bunch of info to be sent at once, which is why I am now going to attempt socket. My question is, using … Read more
adds all the names without leading underscores (or only the names defined in the modules __all__ attribute) in foo into your current module. In the above code with from socket import * you just want to catch timeout as you’ve pulled timeout into your current namespace. from socket import * pulls in the definitions of everything inside of socket but doesn’t add socket itself. Many people consider import * problematic and try … Read more
This way works well when there are multiple network interfaces. It always returns the preferred outbound IP. The destination 8.8.8.8 is not needed to be reachable. Connect on a UDP socket has the following effect: it sets the destination for Send/Recv, discards all packets from other addresses, and – which is what we use – transfers the socket … Read more
I came across the same error. I provided the below command and the issue got solved. COMMAND :- taskkill /f /im adb.exe
Unexpected end of file” implies that the remote server accepted and closed the connection without sending a response. It’s possible that the remote system is too busy to handle the request, or that there’s a network bug that randomly drops connections. It’s also possible there is a bug in the server: something in the request … Read more
