dhcpserver and dhcperf on same machine - still not working

[Rajitha Chinnapu]

Hi,

I installed dhcperf on red hat linux. Here is what i see when i run dhcperf.

/usr/local/nom/bin$ sudo ./dhcperf --server opah --one-discover
Sending DHCPDISCOVER.

No response after 4 seconds: failed to acquire address.
/usr/local/nom/bin$
====================================================================

/usr/local/nom/bin$ sudo ./dhcperf --server opah --discover --clients 20  
--retain-leases
Beginning DHCPDISCOVER load test.
Initial probe complete: High-water mark is 1 clients/second.
0 four-way handshakes per second.
/usr/local/nom/bin$

And then, to account for the drawback in the following post in the groups, i 
installed dhcperf on the same machine that has the dhcp server. but still, it 
gives the same problem. That means, something else is wrong here. any help is 
appreciated.

======================================================================================

dhcperf works really well.  It allows you to test DHCPDISCOVER tps as 
well as RENEW tps.  It starts with 30 clients/sec and then keep working 
its way up.  The one downfall is that it is extremely picky about when 
it needs to receive a response from the server.  I believe it needs to 
receive a response within .1 seconds, if it doesn't it considers that a 
failure.  This is not a real world test by any means, as clients will 
retransmit their requests.  dhcperf does not take this into account. 
======================================================================================


thanks,
rajitha.
