The weird part is this works in Windows perfectly but not Linux. I've looked all over the place for a possible solution but none of them worked. Below is a sanitized version of the code which exploits the bug, however, with a higher success rate. Normally http://stackoverflow.com/questions/24874894/yet-another-connection-reset-by-peer-error it never works. Hopefully this is still enough information. Thanks!

Is it a fatal error or just a notification? sockets tcp share|improve this question edited Apr 19 '13 at 2:04 Nick Caplinger 278310 asked Sep 16 '09 at 17:38 Soubok 5,636113962 add a comment| 2 Answers 2 active oldest votes up vote 413 connection reset by down vote accepted It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description: "Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging.

It sounds like it should be "connection reset by the host", or "connection reset by the server" –Robert Sep 26 '14 at 13:57 12 @Robert Because that's where the reset came from. The peer sent an RST packet. –EJP Dec 17 '14 at 22:44 16 ... Robert, your concern makes no sense to me. Peer is just strictly more general than that. In a typical client-server model, the server can just as easily receive this notification from the "client". The machine that initially requests the connection has just as muc
