Review comment:
       Just as a side-note: I usually added also `-e` as a parameter getting "extended" output. Not sure whether it helps in that case but it's just nice to read for someone who knows German: `netstat -tulpen` 😄

Review comment:
       Are you sure that you want to use `sudo -E sudo #...`? I couldn't test it quickly but it looks strange.
