Hello!

I have problem in communication between subsystems through VPN. Tunnel between subsystems is established and I can ping other server. When i run NodeManager, it sends UDP packages to address 224.1.0.1, source and destination ports are jaus(from Wireshark).
Is this a VPN router problem and why NodeManager sending messages to that unknown address?

Sorry, could not upload .conf file, so it's here:

# This subsection defines the9 JAUS characteristics of the node
[JAUS]
SubsystemId: 110
NodeId: 1
Subsystem_Identification: OJSubsystem110
Node_Identification: OJNode1

# This subsection defines the interfaces and their options for component communication
[Component_Communications]
JAUS_OPC_UDP_Interface: true
OpenJAUS_UDP_Interface: true

# This subsection defines the interfaces and their options for node communication
[Node_Communications]
Enabled: false
#JUDP_Interface:
#JUDP_IP_Address:
#JAUS_OPC_UDP_Interface:
#JAUS_OPC_UDP_IP_Address:

# This subsection defines the interfaces and their options for subsystem communication
[Subsystem_Communications]
Enabled: true
JUDP_Interface: true
JUDP_IP_Address: 172.25.26.10
#JAUS_OPC_UDP_Interface: false
#JAUS_OPC_UDP_IP_Address:



br,

jv

And now we get error "ERROR (void JudpInterface::recvThredRun():755) Invalid JUDP version number in received message" when running Node Manager.
.conf file is still same and we are using Linux version.

-jv

We have also had problems with using VPNs in the past. The issue has to do with the Heartbeat Messages that are sent out to the Multicast address "224.1.0.1". These messages allow the Node Managers to discover each other. Many VPNs do not allow routing of Multicast packets. If your's does, then it might need special configuration to allow these packets. Also, another problem has to do with the Time-To-Live (TTL) value on the packets. This is a value that indicates how many times the packet is allowed to be passed on through a network. When routing over VPN or the Internet, the packet may need to be relayed many times. In which case, you need to manually increase the TTL value by modifying the code. First check to make sure your VPN will allow the Multicast packets, then make sure it is configured properly to do so (if there is a special configuration). Finally, when you're confident those issues are resolved, we can show you how / where to modify the TTL value in the OpenJAUS Node Manager.
