Why does not java support raw sockets?

800670Dec 27 2010 — edited Jan 2 2011
Java does not have support for raw sockets, that means it cannot receive the packet header, just the payload data.
But the header data of an ICMP packet consists of 20 bytes, and you can still write single bytes in Java, so why isn´t is possible to write a header for an ICMP packet in Java?

Can someone explain how it all works?

Thanks!

Unless you are working with a multi-record, single message input in real-time processing, you should not be using message handling script for this.

Unfortunately, it is not very clear what your requirement is.

Try with Group and Merge processor. Group by common value and Take Highest Value in merge sub processor.

It is not advisable to group huge numbers of records (e.g. a whole data set) with Group and Merge.

To determine the max values for each attribute in a data set, you should stage results output of the Max/Min Profiler.
