dhcpserver and dhcperf on same machine - still not working

[Marc Perea]

Hi Rajitha,
 
It's a good step to install dhcperf on the same host as the dhcp daemon runs on - that indicates to me that your DHCP server doesn't want to give addresses to random clients perhaps? Our DHCP server only responds to known hosts, so when I want to run dhcperf I have to add another network, define a class of hosts to test with (so that they'd be known), and allow the class within the range for load testing (implicitly denying the rest of my known clients). The config looks something like this:
 
class "loadtest" { match if (option agent.remote-id = 6d:61:72:63:63:70); }
        subnet 10.170.0.0 netmask 255.255.0.0 { #LOAD TEST
                authoritative;
                option routers 10.170.0.1;
                option subnet-mask 255.255.0.0;
                option broadcast-address 10.170.255.255;
                pool { authoritative; range 10.170.1.1 10.170.254.255; allow members of "loadtest";}
        }

you could also make a host entry (by mac or other identifier) to match with instead of using a class, if that's easier.
 
This is based on the assumption that your DHCP server is somewhat locked down to the clients that it supports - if that's not the case, what are you seeing in the logs when you attempt the dhcperf?
 
dhcperf should work against any DHCP server - it simply pretends to be many dozens/hundreds/thousands of clients coming from a certain network segment - it just so happens that all that happens as emulation from a single host.
 
HTH,
