I am working on my VMWare based installation.

I have recompiled the kernel with the web100 patches:

# grep Web /var/log/dmesg
Web100: initiailizing hash table of size 32768 (order 5)
Web100 2.5.12 200609221010 net100: Initialization successful

# cat /proc/web100/header
2.5.12 200609221010 net100
<snip>

When I am trying to perform the test, I get the following output:
TCP/Web100 Network Diagnostic Tool v5.5.1
click START to begin
Connected to: 192.168.213.128 -- Using IPv4 address
Checking for Middleboxes . . . . . . . . . . . . . . . . . ..Protocol error!

C2S throughput test FAILED!
running 10s inbound test (server-to-client [S2C]) . . . . . . Protocol error!
S2C throughput test FAILED!
Protocol error!

The following ports are opened up on the firewall:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3001 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3002 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3003 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 7123 -j ACCEPT

And the services are being ran as such:

/usr/local/sbin/web100srv -a -l /var/log/web100/web100srv.log
/usr/local/sbin/fakewww -l /var/log/web100/fakewww.log

I removed the -m option to keep the issue of random ports needing to be opened for multiple connections while I am still in this initial testing phase.

I am using the following software versions:

web100-2.5.12-200609221010
web100_userland-1.6
ndt-3.4.1

Any help would be appreciated, if I'm needing to run some debug I'd be happy to do so, but I'm just curious what I should be looking for at this point.
