I expected UDP datagrams to be sent on both sockets. What did you see instead? More often than not, this test fails on Linux: c1 send failed 0: write udp 127.0.0.1:47716->127.0.0.1:34183: sendmsg: operation not permitted It's either the first or the second connection that fails, but...

Because UDP has no real connection and there is no ACK for any packets sent, the best a "connected" UDP socket can do to simulate a send failure is to save the ICMP response, and return it as an error on the next write. So the first packet is sent, an ICMP unreachable message is...

Go UDP socket example UDP is a communication protocol that transmits independent packets over the network with no guarantee of arrival and no guarantee of the order of delivery. One service that used UDP is echo. The Echo Protocol is a service in the Internet Protocol Suite defined in RFC 86...
本程序是通过发送UDP广播,实现网络开机(WOL)的程序,使用 Golang 编写,只编译了Linux AMD64下的版本,其它平台可以自行编译。使用方法:./wakeup -h 11:22:33:44:55:66,唤醒MAC地址为11:22:33:44:55:66的机器。 我以前用C#/Winform写过一个在 Windows的开机编程,位于 http://download.csdn.net/detail/hei...
UDP:支持std net packageDNS消息解析器:根据特定协议处理来自线路的数据包将需要一些工作,为了快速实现,我们将使用golang.org/x/net/dns/dnsmessage转发:除了让我们使用Cloudflare公共解析器1.1.1.1缓存:内存和持久性,对于持久性写入,我们将使用std gob包对数据进行编码HTTP处理程序:应该创建,读取,更新和删除DNS记录。
