ndt-users list created

I am unable to start web100srv on a fedora core5 system linux version 
2.6.15.1 with an ndt configured kernel:  we installed kernel patch 2.5.8 for 
Linux 2.6.15, userland Version 1.5 and ndt-3.1.13.

The installation process seemed to work fine

Syslog shows:

Linux version 2.6.15.1-web100

Fakewww starts successfully at boot time but web100srv does not.  When I 
attempt to start it manually I get the following error:

Server fault: new routine can't bind to IPv4 addresses: Invalid argument

netstat -n -a -A inet –p shows nothing listening on any of the web100srv 
ports (3001, 3002, 3003)

I see the v6 socket references but because of the mention of bind problems 
with IPv4 I wondered what would happen if I disabled  v6 by removing modules 
from the kernel.  

Per something I read I created a file called:
/etc/modprobe.d/00local which contains two lines

alias net-pf-10 off
alias ivp6 off
~

After a boot I no longer see v6 references in the ifconfig 

eth0      Link encap:Ethernet  HWaddr 00:B0:D0:B6:CF:F9
          inet addr:128.173.240.137  Bcast:128.173.243.255  Mask:255.255.252.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1


and I get a different message when I try to start the server:

Server Failed: cannot open socket: Address family not supported by protocol.

I would appreciate any advice about what might be  causing these web100srv 
failures. 

Thanks,
