[RMI] SocketTimeoutException: Read timed out

[Andre Raue]

Hello,

I just started to build a small RMI example for testing purpose.
everything works fine on Windoze. But when I try to start the Server
on Linux I get the exception shown below. I'm using Java SDK 1.4.2_04
on both machines. You'll find my server class and policy file below.

I would be glad about some help...

Greetings

Andre

Hello,

as I am still having trouble to get my RMI-Server started on Linux, I
would like to see, what is happening on port 1099 on Linux and on Win NT.

Does anybody know how to do this. Which software do I need? Any proposals?

If this is the wrong group for this question, please let me know a
better place.

Greetings

Andre

Ethereal is the best tool, a GUI driven packet dump/analyser.
Tcpdump is a similar command line tool.
