Labeless No connection could be made because the target machine actively refused it.

[hpvip161]

I use IDA 7.2 and labeless 1.1.12.85. When I test connect in setting tab, the error message : Test failed, error: Labeless::connectToHost: connect() to 192.168.37.129:3852 failed. Error: 0x0000274d No connection could be made because the target machine actively refused it. Pls help me

Hi @hpvip161, thanks for submitting the issue. Make sure you set up Labeless in debugger, could you show your log from debugger?

I followed the instructions at https://github.com/a1ext/labeless and https://research.checkpoint.com/installing-labeless/. How to check my set up Labeless in debugger. I tested connection was not successful, so i didn't debug.

Start the debugger first, open logs window and make sure there is a line about Labeless. Which debugger do you use? OllyDbg has L button to open logs window, the copy whole table and paste here. x64dbg has Log tab, do the same if you use it. P.S. on OS, starting from win 7 (vista) the OS Firewall will ask you to allow the debugger to listen.

If you see an error like the following:

make sure you installed labeless python module:

c:\python27\python.exe -m pip install labeless
c:\python27x64\python.exe -m pip install labeless

The error appears after I have followed the instructions video your refer. Labeless was already installed in IDA and python module.

@hpvip161 Show me please log from your debugger, not from IDA.
