SANDBOX(8) User Commands SANDBOX(8)
sandbox - Run cmd under an SELinux sandbox
sandbox [-C] [-s] [ -d DPI ] [-l level ] [[-M | -X] -H homedir
-T tempdir ] [ -R runuserdir ] [-I includefile ] [ -W
windowmanager ] [ -w windowsize ] [[-i file ]...] [ -t type ] cmd
sandbox [-C] [-s] [ -d DPI ] [-l level ] [[-M | -X] -H homedir
-T tempdir ] [ -R runuserdir ] [-I includefile ] [ -W
windowmanager ] [ -w windowsize ] [[-i file ]...] [ -t type ] -S
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 $HOME and /tmp, before
deleting.
-t --type
Use alternate sandbox type, defaults to sandbox_t or
sandbox_x_t for -X.
Examples:
sandbox_t - No X, No Network Access, No Open,
read/write on passed in file descriptors.
sandbox_min_t - No Network Access
sandbox_x_t - Ports for X applications to run
locally
sandbox_web_t - Ports required for web browsing
sandbox_net_t - Network ports (for server
software)
sandbox_net_client_t - All network ports
-T --tmpdir
Use alternate temporary directory to mount on /tmp.
Defaults to tmpfs. Requires -X or -M.
-R --runuserdir
Use alternate temporary directory to mount on
XDG_RUNTIME_DIR (/run/user/$UID).
-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/openbox.
-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 --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.
