Hello together,

When I run Nmap I see that Advanced Digi Discovery Protocol Port 2362 is open and I want to close that port. Is that possible?

I only found this:  
“You can enable or disable access to ADDP service, but you cannot change the network port number for ADDP from its default.”, but there is no API in the C code.

Can you help me with that?

PS: I am using netos7.5

Thanks

are you trying to completely disable ADDP? in that case, just do not start the service. in bsp\_services.h:

/\*

- ENABLE\_ADDP\_SERVER is used to activate the ADDP server.
- 
- Set ENABLE\_ADDP\_SERVER to FALSE to disable the ADDP server.
- 
- @external
- @category Networking:ADDPConfiguration
- @since 6.2  
\*/  
#define ENABLE\_ADDP\_SERVER FALSE
