External Tool "issues" and high difficulty to use

[mwiegand]

Hi @carstenhaubold,

Apologize that I am replying delayed. I had to finish of two other tasks first. Your solution, which is awesome, partially works but also reinforces the findings from:

Bash Node: Command not found

Hi there, the Bash – KNIME Hub form the KNIME NGS tools – KNIME Hub works well on commands like curl. However, other commands, which can be executed w/o issues directly in the terminal, like the following, cause an error to be thrown: “Execute failed: Cannot execute command” nmap -v -F google.com Does Knime has its own file which references executables? I checked the preferences but could not find anything, though. Best Mike

The regular commands like ping or nc do work, however nmap fails with the error:

ERROR Python Script 4:852 Execute failed: FileNotFoundError: [Errno 2] No such file or directory: 'nmap'

Reason for that seems that Knime does not use the users PATH variable which is baffling but might have a reasonable / simple explanation. Do you happen to know anything or have an idea which could resolve this mystery?

Best
Mike
