Small Debugging HowTo

Extended debugging output

Two options here:

• Run the whole script with --debug=<number> --log. Then tar -cvzf mydebug.tgz /tmp/ssltester.<randomstring> <nameoflogfile>
• Run the section where the problem is (see --help): script -c "bash -vx testssl.sh optionfortherightsection>"

For <number> see man page.

Debug yourself

1. YMMV

2a) For a full debug output

• (all-in-one output): run script -a mydebug.script -c "SETX=true bash -x testssl.sh <CMDLINE>"
• (separate debugging file): or run "bash -x testssl.sh " and look for last file in /tmp/testssl.s-XXXX.log

2b) spot the section where the bug is

• edit the script and put after the section an exit 0
• switch on debugging either by
  • editing the program and add before a set -x, run the section of the script
  • run the script with bash -x testssl.sh <<optionfortherightsection>>
