putting NIC in promiscuous mode

[FurqanAhmed]

Hi,

I'm looking into the possibility of making a network management software, so naturally it should include a network monitor. But the basic requirement of a network monitor is to be able to put the NIC of the local machine in promiscuous mode. Anyone here know how to put the NIC into promiscuous mode in Java? Even if you know any means like using JNI, let me know.

Thanks
Furqan

perhaps the openSource apache/jakarta-commons -lib has something to say to this issue?

You are unlikely to get that done from pure java. What you want to do is low-level, system dependant and you won't find a native java package to do that for you. What you will need to do is to write a native library (possibly in C) to do the low-level stuff and then pass the captured data up to your java class.

For more information, see the JNI tutorials on java.sun.com
