Dan Tran commented on KARAF-1149:
---------------------------------



dan:  do you mean external firewall or the internal linux iptables?

JB:

I saw the issue today with a customer, with a hardware firewall:

- Karaf is installed on host A
- jconsole is on my laptop

Between A and my laptop, we have a firewall (Cisco IoS) on which I opened the 
required port.

But the JVM bind a random port for the jconsole/JMX communication (specific to 
Sun JVM). A simple workaround is to create a JMX agent.

Regards
JB

> If network administrator opens the network ports to use Karaf MBean server 
> (for instance, by default, 1099 for the RMI Registry and 44444 for the RMI 
> server), the JVM open random port for JMX communication.
> It could be helpful to provide a JMX agent or at least to document how to use 
> Karaf MBean server behind firewalls.
