Hi Rob at al. Im having problems to run modules of oflops. I had a NetFPGA in a PC with openflow switch and other pc with netfpga running oflops. I connect with direct cable the two machines and start openflow in the first.
My output is there. # ./oflops -c eth0 -d nf2c1 -d nf2c0 -p 6633 -g nf2 -t ./example_modules/openflow_mod_flow/.libs/ libopenflow_mod_flow.a libopenflow_mod_flow.so mod_flow.o libopenflow_mod_flow.la libopenflow_mod_flow.so.0 libopenflow_mod_flow.lai libopenflow_mod_flow.so.0.0.0 [root@cobrowser oflops]# ./oflops -c eth0 -d nf2c1 -d nf2c0 -p 6633 -g nf2 -t ./example_modules/openflow_mod_flow/.libs/libopenflow_mod_flow.so Initializing pkt gen library Found net device: nf2c0 counter: 47323b5aade1 4732 be00e5a0 Setting control channel to eth0 Adding a data channel on nf2c1 Adding a data channel on nf2c0 Setting Control listen port to 6633 traffic generator 0 is invalid Sending probe interval : 114 usec (pkt_size: 1500 bytes, rate: 100 Mbits/sec ) Sending probe interval : 114 usec (pkt_size: 1500 bytes, rate: 100 Mbits/sec ) Creating server socket...

Should be used cross connect cables ? What's wrong? The openflows netfpga switch is working fine. Is a problem with the Oflops or with the stupid user? :)
