NAME

Net::Async::Ping::ICMPv6

VERSION

version 0.003003

DESCRIPTION

This is the ICMPv6 part of Net::Async::Ping. See that documentation for full details.

ICMPv6 methods

This module will first attempt to use a ping socket to send its ICMPv6 packets, which does not need root privileges. These are only supported on Linux, and only when the group is stipulated in /proc/sys/net/ipv4/ping_group_range (yes, the IPv4 setting also controls the IPv6 socket). Failing that, the module will send standard RAW packets, which will fail if attempted from a non-privileged account.

Additional options

To disable the attempt to send from a ping socket, set use_ping_socket to 0 when initiating the object:

my $p = Net::Async::Ping->new(
  icmpv6 => {
     use_ping_socket => 0,
  },
);

Return value

Net::Async::Ping::ICMPv6 will return the hires time on success. On failure, it will return the future from IO::Async::Resolver if that failed. Otherwise, it will return as a future failure:

"ICMPv6 Unreachable"

ICMPv6 response was ICMPv6_UNREACHABLE

"ICMPv6 Timeout"

ICMPv6 response was ICMPv6_TIME_EXCEEDED

"Receive error"

An error was received from IO::Async::Socket.
