Hello all,

I am currently running QNX 6.4.1 on our product.

I am looking at some packet traces and see the product (call A) is trying to establish connection to a device(running 
ubuntu, call B) in our network on TCP port 2001. 
This happens when power cycle A. I also saw some ARP broadcast sent from A. it is trying to know the IP of B in the 
network. Then, after B tells A its IP, A is trying to establish handshake on B's port 2001. 

I am very sure all the applications we create do not have used tcp port 2001. 2001 port is used by hackers to open the 
backdoor in the past. malware usually is trying to connect on port 2001.

I am post here in qnx community. QNX experts perhaps could help me to understand what application/service in QNX is 
trying to connect to 2001 port.
