[erlang-questions] Fwd: newbie distel / general node help

Following the notes at http://www.erlang.org/faq/x982.html, which for
some reason I had not managed to stumble across before, I restarted
epmd with "-d -d" and watched the output while starting two nodes on
the same machine with snames, and trying to ping each other. It did
show relevant output while starting the nodes (see excerpt below).
However, when I tried various forms of ping, nothing at all appeared
from epmd.

I will try to see if I can use tcpdump or nc or something to find any packets.

As I (briefly) mentioned in my original post, this is all running in
OpenVZ which is a virtualization system. I wonder if networking
addresses or something get screwy? But I would have expected anything
doing the equivalent of "localhost" to work fine (it does for other
unixy things).
