jailtest - Simple utility program to test running sandboxes
sudo jailtest [OPTIONS] [directory]
WORK IN PROGRESS! jailtest attaches itself to all sandboxes
started by the user and performs some basic tests on the sandbox
filesystem:
1. Virtual directories
jailtest extracts a list with the main virtual directories
installed by the sandbox. These directories are build by
firejail at startup using --private* and --whitelist
commands.
2. Noexec test
jailtest inserts executable programs in /home/username,
/tmp, and /var/tmp directories and tries to run them from
inside the sandbox, thus testing if the directory is
executable or not.
3. Read access test
jailtest creates test files in the directories specified
by the user and tries to read them from inside the
sandbox.
4. AppArmor test
5. Seccomp test
The program is started as root using sudo.
--debug
Print debug messages.
-?, --help
Print options and exit.
--version
Print program version and exit.
[directory]
One or more directories in user home to test for read
access. ~/.ssh and ~/.gnupg are tested by default.
For each sandbox detected we print the following line:
PID:USER:Sandbox Name:Command
It is followed by relevant sandbox information, such as the
virtual directories and various warnings.
