I have checked it out. Seems like there is absolutely no way to configure the source port gdb uses for the udp connection. So one must invoke a "target remote udp:ip:port" command, see what was the chosen source port (tcpdump/netstat), and reconfigure kgdb on the target. While this works, it is rather awkward. Do you think there is/can be another way to solve this issue (like allowing NETPOLL to listen to a wildcard udp source port) ? thank you naziir > > -- > Mathematics is the supreme nostalgia of our time. > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
