I'm using NDT from SourceForge's CVS
(http://ndt.cvs.sourceforge.net/ndt/ndt/src/web100clt.c?view=log) on FreeBSD
4.11-STABLE and it fails with the following error:

read failed read 'Go' flag

Here is the debug output:

$ ./web100clt -dddddd miranda.ctd.anl.gov
Testing network path for configuration and performance problems -- Using
IPv4 addresses
read 1 octets '0'
Test port numbers not received, read 2nd packet to get them
Testing will begin using port 3003 and 3002
connecting to 146.137.222.101:3003

Checking for Middleboxes . . . . . . . . . . . . . . . . . . CWND limited

read failed read 'Go' flag


Is there a better version of NDT that I should be using? I tried the version
linked from the E2EPI website (3.1.4b), but that fails with an EPIPE error.

$ ./web100clt -dddddd miranda.ctd.anl.gov

Thanks in advance for your help.
