net: ListenIP doesn't support Linux-specific ICMP echo-only socket #9166
Labels
Comments
Thanks but no thanks. it's a protocol stack inside Linux kernel specific feature, also it cannot receive/send other ICMP type messages. You can make your Linux+ICMP echo-specific socket using syscall.Socket and make it run with runtime-integrated network poller by using net.FilePacketConn. Labels changed: added repo-main. Status changed to Unfortunate. |

fwiw, now golang.org/x/net/icmp supports non-privileged datagram-oriented icmp socket. see http://godoc.org/golang.org/x/net/icmp for further information. |

I want to open a ping socket, but I can't because `net.ListenIP("ip4:icmp", ...)`[1] always uses type=SOCK_RAW. However, for "ip4:icmp" / "ip6:ipv6-icmp" it should use type=SOCK_DGRAM. I also can't work around it by using `net.ListenUDP` because that always uses proto=0 (= default = UDP for SOCK_DGRAM).
