disable_exec

Description

Type integer READ/WRITE

Use disable_exec to prevent the runcommand process from executing new UNIX processes. For example, you can prevent a vi session from executing shell commands. This variable is only supported if the underlying operating system supports the noexec feature; that is, Linux, Solaris, HP-UX, and AIX. If set to true(1), Safeguard sets the LD_PRELOAD environment variable, which causes the runcommand to be loaded with a Safeguard library that overrides the system exec functions, and thus prevents the runcommand from using exec to create a new process.
