SANDBOX(8) User Commands SANDBOX(8)NAME
sandbox - Run cmd under an SELinux sandbox
SYNOPSIS
sandbox [-C] [-c] [-s] [ -d DPI ] [-l level ] [[-M | -X] -H homedir -T tempdir ] [-I includefile ] [ -W windowmanager ] [ -w windowsize ]
[[-i file ]...] [ -t type ] cmd
sandbox [-C] [-c] [-s] [ -d DPI ] [-l level ] [[-M | -X] -H homedir -T tempdir ] [-I includefile ] [ -W windowmanager ] [ -w windowsize ]
[[-i file ]...] [ -t type ] -S
DESCRIPTION
Run the cmd application within a tightly confined SELinux domain. The default sandbox domain only allows applications the ability to read
and write stdin, stdout and any other file descriptors handed to it. It is not allowed to open any other files. The -M option will mount
an alternate homedir and tmpdir to be used by the sandbox.
If you have the policycoreutils-sandbox package installed, you can use the -X option and the -M option. sandbox -X allows you to run X
applications within a sandbox. These applications will start up their own X Server and create a temporary home directory and /tmp. The
default SELinux policy does not allow any capabilities or network access. It also prevents all access to the users other processes and
files. Files specified on the command that are in the home directory or /tmp will be copied into the sandbox directories.
If directories are specified with -H or -T the directory will have its context modified with chcon(1) unless a level is specified with -l.
If the MLS/MCS security level is specified, the user is responsible to set the correct labels.
-h --help
display usage message
-H --homedir
Use alternate homedir to mount over your home directory. Defaults to temporary. Requires -X or -M.
-i --include
Copy this file into the appropriate temporary sandbox directory. Command can be repeated.
-I --includefile
Copy all files listed in inputfile into the appropriate temporary sandbox directories.
-l --level
Specify the MLS/MCS Security Level to run the sandbox with. Defaults to random.
-M --mount
Create a Sandbox with temporary files for $HOME and /tmp.
-s --shred
Shred temporary files created in $HOME and /tmp, before deleting.
-t --type
Use alternate sandbox type, defaults to sandbox_t or sandbox_x_t for -X.
Examples:
sandbox_t - No X, No Network Access, No Open, read/write on passed in file descriptors.
sandbox_min_t - No Network Access
sandbox_x_t - Printer Ports
sandbox_web_t - Ports required for web browsing
sandbox_net_t - All network ports
-T --tmpdir
Use alternate temporary directory to mount on /tmp. Defaults to tmpfs. Requires -X or -M.
-S --session
Run a full desktop session, Requires level, and home and tmpdir.
-w --windowsize
Specifies the windowsize when creating an X based Sandbox. The default windowsize is 1000x700.
-W --windowmanager
Select alternative window manager to run within sandbox -X. Default to /usr/bin/matchbox-window-manager.
-X Create an X based Sandbox for gui apps, temporary files for $HOME and /tmp, secondary Xserver, defaults to sandbox_x_t
-d --dpi
Set the DPI value for the sandbox X Server. Defaults to the current X Sever DPI.
-c --cgroups
Use control groups to control this copy of sandbox. Specify parameters in /etc/sysconfig/sandbox. Max memory usage and cpu usage
are to be specified in percent. You can specify which CPUs to use by numbering them 0,1,2... etc.
-C --capabilities Use capabilities within the
sandbox. By default applications executed within the sandbox will not be allowed to use capabilities (setuid apps), with the -C
flag, you can use programs requiring capabilities.
