I think I figured out the problem
This computer has two NICs..- the onboard one (en0) and a PCI GigE
one (en1). The system is only connected to our LAN via en1.. en0 has
nothing tied to it - it would appear that ganglia is talking /
listening on en0, and not en1
somehow I need to get it to talk out en1 (or swap my network cables
around....)

I ran into a similar problem with some of our systems. The issue
(in our case) was that different hosts had different IP filter
settings. Depending on your OS, this might be done with the
ipchains, iptables or ipfilter tools (among many other ways of
doing it).
Can you telnet to 192.168.181.83 port 8649 from the original host
you ran gstat from?

Hi..
I have an odd problem (I think).
When I try to run gstat -i, the answers I get back
[Chris-AlBook:~] cmyip% gstat -i 192.168.181.83
gexec_cluster() XML_ParseBuffer() error at line 1:

Unable to get hostlist from 192.168.181.83 8649!

Seem to depend on what machine I'm using to get the information...
- this even happens for two identical machines that are connected
identically
to a switch - one machine will get the "no element" found message,
the other
will get the right information. Oddly enough - this was working
before I
relocated my lab - the only change has been the installation of
GigE switch...
I'm not sure what the problem is - has anyone run into similar
problems?
Thanks
Chris
