HAM access not working to remote node entity in QNX 6.5.0 and QNX 6.5.0 SP1
We have functional HAM access to a node in QNX 6.3.0 over qnet.
This worked in QNX 6.3.0 but is not working in QNX 6.5.0 and QNX 6.5.0 SP1
We have two machines, "machine 1" and "machie 2", that can see each other over qnet.
"app1" , running on "machine 1" with entity name "app1_e" attaches to the ham on "machine1" and can be seen as "/net/
machine1/proc/ham/app1_e" directory.
"app2" , running on "machine 2"with entity name "app2_e" attaches to the ham on "machine2" and can be seen as "/net/
machine2/proc/ham/app2_e" directory.
"app2" is able to connect to "machine1" ham using ham_connect_node("machine1", 0);
However it is not able to then get the entity handle for "app1" on "machine1" using:
ham_entity_handle_node("machine1","app1_e", 0);
Debugging the issue revearled that we get an errno of 2, when the function returns from the above call, which means that
it could not find the entity name. We also verified that "app2" running on "machine 2" is able to access the directory
"/net/machine1/proc/ham/app1_e" using the access function.
1) Any idea why we are having this issue on QNX OS 6.5.0?
2) Why can it not find the entity handle on a remote node?
