MOLLY-GUARD(8) [FIXME: manual] MOLLY-GUARD(8)NAME
molly-guard - guard against accidental shutdowns/reboots
SYNOPSIS
shutdown [-hV] [--molly-guard-do-nothing] [-- script_options]
halt [-hV] [--molly-guard-do-nothing] [-- script_options]
reboot [-hV] [--molly-guard-do-nothing] [-- script_options]
poweroff [-hV] [--molly-guard-do-nothing] [-- script_options]
DESCRIPTION
molly-guard attempts to prevent you from accidentally shutting down or rebooting machines. It does this by injecting a couple of checks
before the existing commands: halt, reboot, shutdown, and poweroff. This happens via scripts with the same names in /usr/sbin, so it only
works if you have /usr/sbin before /sbin in your PATH!
Before molly-guard invokes the real command, all scripts in /etc/molly-guard/run.d/ have to run and exit successfully; else, it aborts the
command. run-parts(1) is used to process the directory.
molly-guard passes any script_options to the scripts, and also populates the environment with the following variables:
o MOLLYGUARD_CMD - the actual command invoked by the user.
o MOLLYGUARD_DO_NOTHING - set to 1 if this is a demo-run.
o MOLLYGUARD_SETTINGS - the path to a shell script snippet which scripts can source to obtain settings.
molly-guard prints the contents of /etc/molly-guard/messages.d/COMMAND or /etc/molly-guard/messages.d/default to the console, if either
exists. This is due to /etc/molly-guard/run.d/10-print-message.
GUARDING SSH SESSIONS
molly-guard was primarily designed to shield SSH connections. This functionality (which should arguably be provided by the openssh-server
package) is implemented in /etc/molly-guard/run.d/30-query-hostname.
This script first tests whether the command is being executed from a tty which has been created by sshd. It also checks whether the
variable SSH_CONNECTION is defined. If any of these tests are successful, test script queries the user for the machine's hostname, which
should be sufficient to prevent the user from doing something by accident.
You can pass the --pretend-ssh script option to molly-guard to pretend that those tests succeeds. Alternatively, setting
ALWAYS_QUERY_HOSTNAME in /etc/molly-guard/rc causes the script to always query.
The following situations are still UNGUARDED. If you can think of ways to protect against those, please let me know!
o running sudo within screen or screen within sudo; sudo eats the SSH_CONNECTION variable, and screen creates a new pty.
o executing those command in a remote terminal window, that is a XTerm started on a remote machine but displaying on the local X server.
You have been warned. You can use the --molly-guard-do-nothing switch to prevent anything from happening, e.g. halt
--molly-guard-do-nothing.
OPTIONS --molly-guard-do-nothing
Cause molly-guard to print the command which would be executed, after processing all scripts, instead of executing it.
