Answer to fun questions

This is just my answer template for "Fun questions" section on sysadmin interview repo:

A careless sysadmin executes the following command: chmod 444 /bin/chmod - what do you do to fix this?

First of all, I'd get the root privileges from that person away. As answer, I have 2 solutions:

  1. I'd create a dumb FS (like fat) on a loopback device and copy this file to there, since every file will have executable rights there.
  2. There is no problem, system is running without problems, so no need to fix.

I've lost my root password, what can I do?

Things to do to get fired (Linux version)
  • Set id:6:initdefault in /etc/inittab file
  • Write a script for system to randomly delete a single file without telling you every time you made a typographical error (wrong command).
  • chattr +i /etc/passwd or shadow, actually saw this on a server
  • add export PROMPT_COMMAND="cd" to profile file
  • chmod -x $(which chmod) or chmod -x $(readelf --header /bin/ls | grep interpreter | awk '{print $4}' | sed 's/]//')
  • upside-down-ternet
  • export EDITOR=$(which rm)
