+.TH SANDBOX "8" "May 2009" "chcat" "User Commands"

+.SH DESCRIPTION

+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
+.I policycoreutils-sandbox
+package installed, you can use the -X option.
+package installed, you can use the -X option and the -M option.
+.B sandbox -X
+allows you to run sandboxed X applications. These applications will start up their own X Server and create a temporary homedir and /tmp. The default policy does not allow any capabilities or network access. It also prevents all access to the users other processes and files. Any file specified on the command line will be copied into the sandbox.
+
+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 directories need to have a matching label.
