今天遇到同样问题，简单搜索了一下，go 1.11 发布后事情简单了点，net 的 dialer 里增加了 Control 的 handler 方便对 socket 进行操作，如下：
---------------------------------
net.Dialer{
Control: func(network, address string, c syscall.RawConn) error {
return c.Control(func(fd uintptr) {
err := syscall.SetsockoptString(int(fd), syscall.SOL_SOCKET, 25, "ppp0")
if err != nil {
log.Printf("control: %s", err)
return
}
})
},
}
---------------------------------
net.Dialer{
Control: func(network, address string, c syscall.RawConn) error {
return c.Control(func(fd uintptr) {
err := syscall.SetsockoptString(int(fd), syscall.SOL_SOCKET, 25, "ppp0")
if err != nil {
log.Printf("control: %s", err)
return
}
})
},
}
