With your 3.1.13 tarball...

$ ./web100clt -dddddd -llllll 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

Send buffer set to 32768, Receive buffer set to 57344
Checking for Middleboxes . . . . . . . . . . . . . . . . . .  CWND  
limited speed = Inf Kbps
Done

And then nothing.  I did an strace on the process and all I see is  
"read(3, ".
