ndt-users list created

All,
We're getting odd errors at the end of testing that indicate a client
timeout.
Code being executed is specifically line 1265 of Tcpbw100.java.
Furthermore, the Stats and More Information fields occasionally have scant
information after running tests. 
Throughput tests do seem to work, however, which makes things a bit
perplexing. 

OS is Ubuntu 9.04 running kernel 2.6.28
web100-2.5.23
web100_userland-1.7
ndt-3.5.0

We do run a firewall on the ndt server, but have ICMP, and TCP/3001-3003
open.  I have tested with the firewall turned off with the same results.
Any help would be greatly appreciated.
Thanks,
Tate
