Since it is very nasty trying to add this
ourselves, please add an API to the ICMP
protocol so we can ping and traceroute, etc
from Java applets

I want to create a distributed network resource management tool using Java and CORBA. I require the ability to discover the topology of a network. Current methods use DNS, ICMP and SNMP. ICMP is part of IP datagram. There is no ability to modify IP packets or use raw sockets in Java. I have encountered many programmers who wish that tools such as ping and traceroute can be implemented in pure Java, thus making it trully portable and also to give the desired/correct results.

We absolutely need some sort of ICMP and TCP packet access
from java.net.*

Without this, it is *impossible* to write any non-trivial
network monitoring, control or reporting application.
If I need to monitor machines on my network to see if they
are up or the network status/saturation, well, I cannot do
this without ICMP.

This is a major major drawback with java.net.*
Why not just add this support with the appropriate security
permissions ?

There is NO reason why an application, in java, cannot access
ICMP. More and more network tools, servers etc are written
in java. Without support for just a core function, these
tools are never going to be anything else than toy applications.
