if you take a look in http://matt-massie.com/ganglia/ you will see the latest 3.0.0. distribution.
the biggest change is the way that IPv6 addresses are handled (thanks to feedback from brooks). the tcp_accept_channel and udp_recv_channel documentation have the following addition.
The family address is set to inet4 by default. If you want to bind
the port to an inet6 port, you need to specify that in the family
attribute. Ganglia will not allow IPV6=>IPV4 mapping (for
portability and security reasons). If you want to listen on both
inet4 and inet6 for a particular port, explicitly state it with
the following:
udp_recv_channel {
port = 8666
family = inet4
}
udp_recv_channel {
port = 8666
family = inet6
}
If you specify a bind address, the family of that address takes
precedence. f your IPv6 stack doesn't support IPV6_V6ONLY, a
warning will be issued but gmond will continue working (this
should rarely happen).
unfortunately, linux kernels around 2.4.20 have ipv6 support but don't have IPV6_V6ONLY option support. unfortunate. i have it setup to give the person a warning but gmond will still continue.
by default the family is assumed to be "inet4".
udp_recv_channel {
port = 8649
}
will listen for inet4 traffic alone on port 8649.
feedback very welcome.
