Hi all, I seem to be having some problems with iperf and I'm not sure where to begin with debugging. To start, it appears that the iperf daemon dies when running a simple tcp test with the dualtest flag enabled. After the test is run, I see iperf as a defunct process.
Next, tradeoff testing isn't reporting the results back to the client: Client Side: [EMAIL PROTECTED] ~]$ iperf -c 10.34.93.168 -r ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 10.34.93.168, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 5] local 10.34.93.105 port 48703 connected with 10.34.93.168 port 5001 Waiting for server threads to complete.
