[OT] munin



Hey all,

I installed munin on my network, and wrote a puppet module to push out
the munin-node.conf to each machine. Everything seems to work fine,
and 9 machines are reporting in and generating graphs, but 5 are not.
The configs are identical with the exception of the hostname. Here's
the rub. Of the 5 machines, 4 are openvz containers, and one is a
physical machine. 3 are running sid and 2 are running wheezy. (the 9
that are reporting are a mix of lenny, squeeze, wheezy and sid, and
are both physical and openvz containers.)

When I telnet to localhost 4949, it gives me connection refused on all
5 servers, but munin-node is running on all 6. Now here is something
interesting. On all of the nodes I have checked, it appears to be
listening on the ipv6 address:

netstat -pant | grep 4949
tcp6       0      0 :::4949                 :::*
LISTEN      27585/munin-node

this is on both the working and non-working nodes. My network is not
running ipv6. In fact, net-pf-10 is commented out on all the hosts
that I have checked. Here is a snippet from my
/var/log/munin/munin-node.log. This was a /etc/init.d/munin-node
restart, a telnet localhost 4949 (nothing written to the logs) and a
telnet ::1 4949

Can anyone tell me why these 5 nodes will not connect to the server
and refuses connections to localhost and ::1?

Thanks,
--b
