helping each other. Join them; it only takes a minute: Sign up C++ connect function error - Invalid argument up vote 1 down vote favorite I'm trying to make a simple socket client (using debian 6 and g++ http://stackoverflow.com/questions/886782/c-sockets-raises-error-code-22-einval-invalid-argument compiler) and when I'm calling "connect" function, it returns error code 22 - Invalid argument. Tell me, what am I doing wrong, please. I've read the man page for this function and it says that the 3 arguments must be as followed: int, struct sockaddr* and socklen_t. My code is: int serverPort; u_long serverHost; struct sockaddr_in serverAddress; socklen_t serverAddressLength; int clientSocket; serverPort = 44444; serverHost = inet_addr ( "88.198.237.65" ); serverAddress.sin_family = AF_INET; serverAddress.sin_port = htons http://stackoverflow.com/questions/11797365/c-connect-function-error-invalid-argument ( serverPort ); serverAddress.sin_addr.s_addr = htons ( serverHost ); serverAddressLength = sizeof ( serverAddress ); clientSocket = socket ( AF_INET , SOCK_STREAM , 0 ); connect ( clientSocket , (sockaddr*)&serverAddress , serverAddressLength ) c++ sockets arguments connect share|improve this question edited Aug 3 '12 at 14:22 asked Aug 3 '12 at 14:08 Kolyunya 2,29121947 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted serverAddress.sin_addr.s_addr = htons ( serverHost ); An IPv4 address is a long, not a short, so htons is right out. The data is in network byte order already anyway, so no conversion is needed. The inet_addr() function converts the Internet host address cp from IPv4 numbers-and-dots notation into binary data in network byte order. Also: char serverHost; How's it supposed to fit in a char? share|improve this answer answered Aug 3 '12 at 14:11 David Schwartz 108k899163 wrt to your final question - Luck?! –Ed Heal Aug 3 '12 at 14:17 Thank a lot, David! May i ask you, why if I don't apply htons to serverHost on the server side, bind function returns "Cannot assign requested address" and returns "Socket binded successfully" if I DO use htons? Thanks a lot again! –Kolyunya Aug 3 '12 at 14:30 @Kolyunya: Don't try to understand known buggy code. It will just make you cra
a specific error. There are various reasons for an error message, and we troubleshoot each situation differently. For your convenience we gathered a list of common errors, explain what they mean, https://incapsula.zendesk.com/hc/en-us/articles/209074918-Common-Incapsula-Errors-and-Their-Solutions- and suggest how to troubleshoot them. Connectivity errors: Error code 20 Error code 8 Security errors: Error codes 14-17 SSL errors: Error codes 29 Error code 26 Resolving error: Error codes 22 Violation of terms: https://forums.sabnzbd.org/viewtopic.php?t=2437 Error codes 18 Error code 20 General description : Request was not completed due to a failure to connect to the server - TCP Timeout error 22 The Error code 20 is a timeout connection error, which indicates that Incapsula was not able to connect to the origin server. As a result the user will see an Error code 20. This problem may happen due to these reasons: The Incapsula IPs are not whitelisted on the connect error 22 origin server or firewall, as a result that a server or firewall may block or perform a rate limiting on the Incapsula IPs. Please read this article for more information. The server is malfunctioning and dropping requests. The origin server is taking too long to respond to the request. There’s a local issue with an upstream provider. There are network issues between Incapsula and the origin server. You may monitor the Incapsula network here. Solution: Making sure that Incapsula IPs are whitelisted and the origin server is restricted to direct access in most cases will resolve the issue. You may find the list of Incapsula IPs here. Please also make sure that the origin server is up and running with no faults. Check with your hosting provider to assist you with applying the required restrictions and whitelists. We’ve listed the reasons that are the most common causes for triggering an Error code 20, but they are not the only reasons. If you require any assistance, please contact Incapsula support for further investigation.

Best bet - remove the ipv6 servers, OR get in on some .50 lovin' where you can make servers optional Further edit - instead of removing, I just the # of connections to 0 for eweka, newzilla works fine. The beta apparently gets around this by allowing some servers to be optional, instead of killing all connections if one can't connect. Last ed
