pmshell_cmdtype

Description

Type integer READONLY

pmshell_cmdtype is only defined if the command is a shell subcommand running from a Privilege Manager shell.

This variable is only applicable to the pmsh, pmcsh, pmksh, and pmbash programs.

It is set to one of these constant values: pmshell_builtin, pmshell_script, or pmshell_exe.

Example
if (defined pmshell_cmd){ 
   if (user !in safe_shell_list) 
   { 
      #check builtins 
      pmshell_checkbuiltins=true; 
   } 
}

pmshell_exe

Description

Type integer READONLY

pmshell_exe contains a constant value that identifies a normal executable command. Use it to compare with the value of the pmshell_cmdtype variable.

Example
if (defined pmshell_cmd){ 
   if (pmshell_cmdtype == pmshell_exe) 
   { 
      if (basename(runcommand) in shell_sub_list) { 
         accept; 
      } 
   } 
}

pmshell_interpreter

Description

Type integer READONLY

pmshell_interpreter is only defined if the command is running from within a Privilege Manager shell program. If the shell subcommand is an interpreted script (that is, the first line of the file contains a directive in the format #!<path>) then this variable contains the pathname of the interpreter identified by this directive. Use this variable to detect and reject a user from running an unrestricted shell script from within a restricted shell program.

Example
if (defined pmshell) 
{ 
   printf("Starting %s shell\n", pmshell_prog); 
   accept; 
} 
if ((defined pmshell_cmd) && (pmshell_cmd == true)) 
{ 
   # if running a restricted shell, then don't allow the user to run a shell 
   # script unless it's a Privilege Manager shell 
   if (pmshell_restricted && (pmshell_cmdtype == pmshell_script)) 
   { 
      if (dirname(pmshell_interpreter) != "/opt/quest/bin") 
      { 
         reject "Restricted shell only permits you to run a shell in the 
					/opt/quest/bin directory"; 
      } 
   }

pmshell_prog

Description

Type string READONLY

pmshell_prog is only defined if a Privilege Manager shell program is running. If a shell is running, it is set to the name of the shell program (pmsh, pmcsh, pmksh, pmloginshell, or pmbash).

Example
if (defined pmshell) 
{ 
   printf("Starting %s shell\n", pmshell_prog); 
   accept; 
}
