Lack of IPv6 support

What steps will reproduce the problem? 1. Start the samplicator on some port
2. Send UDP packets to that port over IPv6 What is the expected output? What do you see instead? Expected: The packets should be replicated to the configured destinations.
Instead, they are dropped by the host's network stack, because the
samplicator process uses an IPv4-only socket.

Similarly, when IPv6 addresses are specified as destinations, the
samplicator complains about malformed addresses.

Ideally, the samplicator should even be able to receive datagrams over IPv4
and distribute them over IPv6 and vice versa.

IPv6 support could be added as follows:

• In all places where IPv4 addresses are accepted (-s option, receiver addresses on
  the command line or in configuration files, and source address ranges in
  configuration files), we will accept IPv4 addresses, IPv6 addresses, or hostnames.
• In source address range specifications in configuration files, the current (old)
  code understands IPv4 netmasks with the syntax 1.2.3.0/255.255.255.0. We will extend
  the syntax to accept CIDR prefix lengths, e.g. 1.2.3.0/24. For IPv6, only prefix
  lengths will be permitted.
• There will be additional command-line options -4' and-6', which will select a
  specific address family when hostnames are used, or when the default (unspecific)
  listening address is used.
• Source address spoofing will be implemented in a different way for IPv6, namely
  using IN6_PKTINFO. This requires the spoofed source address to be configured as a
  local address on the machine.

I have some code, but I'm not quite happy about it: The IPv6 code may have portability
issues, and I'm not sure about the usefulness of the new limited spoofing, where the
spoofed source addresses must be configured on the machine samplicator runs on. In
addition, I reorganized the code throughly, so it'll be a while until I get to commit
this to the trunk. If anyone wants a pretest snapshot to help me weed out obvious
bugs, please let me know.

Basic support for IPv6 has finally been checked in. Please review revision r126 : https://code.google.com/p/samplicator/source/detail?r=126

Status: Fixed

Any chance of getting spoofing for IPv6? I don't need this yet, but I eventually might. Thanks!

Good question, and maybe I shouldn't have closed this issue so fast. Let's discuss IPv6 spoofing mode support in issue #17 .
