Hello, Could you tell me with version of jpcap and jdk you currently use with Pyxida ? Because I've tried compiling with jpcap 0.5.1 source and there's some errors with (with the lastest code of pyxida), I tried the jpcap.rar file (I dont know what version it is) on the CVS repository, no error on compiling but there's a runtime error : "Exception in thread "Thread-2" java.lang.NoSuchMethodError: setRoutingOption at jpcap.JpcapCaptor.nativeOpenLive(Native Method) at jpcap.JpcapCaptor.openDevice(JpcapCaptor.java:68) at edu.harvard.syrah.pyxida.ping.JpcapPinger$1.run(JpcapPinger.java:107) I tried with both jpcap 0.6 and 0.7 on its site but there's the same error. (I use jdk1.6.0_13). Thank you very much for your help. Jonathan Ledlie wrote: > > Yeah, that's not going to work as is.
