remote debugging - remote server is different OS from local server

[Loreton]

• VSCode Version: 1.17.2
• OS Version: Windows 7

Steps to Reproduce:

1. prepare code on linux using netiface module
   2.run debug from windows to remote linux
   When the local module (windows), in my case "netifaces", has different characteristics from remote module (linux) we get error reading the network interface caracteristics. Why? It should run remote code and not local code.

@Loreton How does your launch config look like?

myLibName = ['LnPyLib', 'DDNS_v2018-02-27.zip']   **_<=== BreakPoint_**
LnLib     = Prj.SPE.LibPath(myLibName, fDEBUG=False)

Problem

When I start the debugger I can STEP just the first two line and the I get an error regarding a missing feature of netifaces module (AF_PACKET).

File "y:\GIT-REPO\Python3\DDNS_main_.py", line 79, in
Prj.Main(gv.args.firstPosParameter)
File "y:\GIT-REPO\Python3\DDNS\Source\Main\DDNS_Main.py", line 83, in Main
interfaces = Ln.getInterfaces(dictType=Ln.Dict)
File "y:\GIT-REPO\Python3\DDNS\LnPyLib\Net\InterfacesCl.py", line 418, in getInterfaces
ifc = Interfaces(ifcName)
File "y:\GIT-REPO\Python3\DDNS\LnPyLib\Net\InterfacesCl.py", line 116, in init
self.arpPing(self._gatewayIpAddress)
File "y:\GIT-REPO\Python3\DDNS\LnPyLib\Net\InterfacesCl.py", line 319, in arpPing
macAddressHex = bytes.fromhex(self._MAC_address.replace(':',''))
AttributeError: 'NoneType' object has no attribute 'replace'

But this feature is missed just in windows module and not in linux one.
In any case:

1. it doesn't stop in the breakpoint line.
2. the TCP connection to remote machine NOT starts

launch extract configuration

   "configurations": [
        {
            "name": "Python",

            ]
        },
    ....
    i have the following tunnel ssh -L 3001:destMaschine:3000 
        {
