Join them; it only takes a minute: Sign up recvfrom: Bad address, sendto: Address family not supported by protocol up vote 0 down vote favorite i'm trying to implement a little UDP-Server/Client Application in C and got two errors on Server-side: recvfrom: Bad address && sendto: Address family not recv error bad address supported by protocol. I searched for the mistake and googled for answers but, unfortunately, they wasn't really helpfully... maybe i'm casting a parameter in a wrong way and don't get it.

I am using send and recv to pass messages. I have a pointer to an array of char pointers... Code: char* args[3]; /* * Fill the array with strings appropriately... */ Later, I try to send this pointer from my client to my server like so: Code: int send_status = send(socket_descriptor, args, sizeof(args), FLAGS); On the server side, I am receiving the message like this: Code: char** str; message_length = recv(c

Bad address. #16 Closed JeremyGrosser opened this Issue Feb 4, 2013 · 3 comments Projects None yet Labels None yet Milestone No milestone Assignees No one assigned 2 participants JeremyGrosser commented Feb 4, 2013 When I start statsite and send UDP messages to it (eg. "cn.nginx.latency:45|ms\n"), I see the following message on stdout: statsite[7686]: Failed to recv() from connection [7]! Bad address. Digging in a bit more, these start once statsd receives a malformed stat on the udp port. For example: my.stats.are.bad With no value causes close_client_connection(handle->conn); to be called on the UDP socket in conn_handler.c:308. This causes all further recv() calls to that socket to fail. JeremyGrosser commented Feb 4, 2013 Seeing the same issue with malformed values as well as missing ones. [pid 18891] recvfrom(7, "dispatch.production.foo:undefined|g", 262143, 0, NULL, NULL) = 53 [pid 18891] sendto(3, "<132>Feb 4 22:46:16 statsite[18890]: Failed value conversion! Input: undefined", 79, MSG_NOSIGNAL, NULL, 0) = 79 Owner armon commented Feb 4, 2013 Thanks for reporting. I added an integration test to confirm this and sure enough it's there. The fix and the test for it are now in master. Please give that a try. I think the issue is closed now. Owner armon commented Feb 5, 2013 Marking this as closed now. armon closed this Feb 5, 2013 Sign up for free to join this conversation on GitHub. Already have an account?
