I've got the aglets-2.0.1
I've got the java runtime environment j2sdk1.4.1

I've one Linux red hat 7.0 Guinness, Kernel 2.2.16-3smp
on a 2-processor i686 -> machine A

I've one Linux red hat 7.0 Guinness, Kernel 2.2.16-22 on
an i686 -> machine B

when I dispatch one agent from A to B, i've the following
errors :

on machine A :

code = 400

    check ur java policy file, to see whether remote aglets have
    permission to do the things u r trying to do in the aglet

    First of all check that the two machines can see each other. In this sense try the DNS resolution (I see the destination machine is called jade) and nmap the machines to see if the aglet platform is running and is not behind a firewall that is blocking connections.
    I've tried the same experiment with the new 2.0.2 platform between two linux and even between linux and windows machines and it worked for me.
