[-U <user>]
The Privilege Manager for Unix Bourne Shell (pmsh) command is a fully featured version of sh, that provides transparent authorization and auditing for all commands submitted during the shell session. pmsh supports the standard options for sh.
Using the appropriate policy file variables, you can configure each command entered during a shell session, to be:
Once allowed by the shell, or authorized by the policy server, all commands run locally as the user running the shell program.
pmsh has the following options.
| Option | Description |
|---|---|
|
-a |
Flags variables for export when assignments are made to them. |
|
-b |
Enables asynchronous notification of background job completion. (UNIMPLEMENTED) . |
|
-B |
Allows the shell to run in the background. |
|
-c <file> |
Reads commands from a file instead of from standard input. |
|
-C |
Does not overwrite existing files with `>'. |
|
-e |
Exits immediately if any untested command fails in non-interactive mode. The exit status of a command is considered to be explic- itly tested if the command is part of the list used to control an if, elif, while, or until; if the command is the left hand oper- and of an ``&&'' or ``||'' operator; or if the command is a pipe- line preceded by the ! operator. If a shell function runs and its exit status is explicitly tested, all commands of the function are considered to be tested as well. |
|
-E |
Enables the built-in emacs(1) command line editor (disables the -V option if it has been set; set automatically when interactive on terminals). |
|
-f |
Disables pathname expansion.. |
|
-h |
A do-nothing option for POSIX compliance. |
|
-i |
Forces the shell to behave interactively. |
|
-I |
Ignores EOF's from input when in interactive mode. |
|
-m |
Turns on job control (set automatically when interactive). |
|
-n |
If not interactive, reads commands but do not run them. This is useful for checking the syntax of shell scripts. |
|
-o <option> |
Sets the specified shell option. A list of shell options can be displayed using the set -o builtin command. |
|
-s |
Reads commands from standard input (set automatically if no file arguments are present). This option has no effect when set after the shell has already started running (i.e., when set with the set command). |
|
-u |
Writes a message to standard error when attempting to expand a variable, a positional parameter or the special parameter ! that is not set, and if the shell is not interactive, exit immediately. |
|
-v |
The shell writes its input to standard error as it is read. Useful for debugging. |
|
-V |
Enables the built-in vi command-line editor (disables -E if it has been set). |
|
-x |
Writes each command (preceded by the value of the PS4 variable subjected to parameter expansion and arithmetic expansion) to standard error before it is run. Useful for debugging. |
pmsh supports the following builtin commands:
., :, [, alias, bg, break, cd, chdir, command, continue, echo, eval, exec, exit, export, false, fg, getopts, hash, jobs, kill, local, printf, pwd, read, readonly, return, set, shift, test, times, trap, true, type, ulimit, umask, unalias, unset, wait
pmshellwrapper
Use the pmshellwrapper program as a wrapper for any valid login shell on a host. It provides full keystroke logging for any normal shell, but does not provide authorization of the commands run from the shell.
To use pmshellwrapper, you must create a link for the real shell you want to use. For example:
ln –s /opt/quest/libexec/pmshellwrapper /opt/quest/bin/pmshellwrapper_bash
When the user runs pmshell_bash, it transparently converts this to pmrun bash.
pmsrvcheck --csv [ --verbose ] | --help | --pmpolicy | --primary | --secondary
Use pmsrvcheck to verify that a policy server is setup properly. It produces output in either human-readable or CSV format similar to that produced by the preflight program.
The pmsrvcheck command checks:
pmsrvcheck produces output in either human-readable or CSV format similar to the pre-flight output.
pmsrvcheck has the following options.
| Option | Description |
|---|---|
| --cvs | Displays csv, rather than human-readable output. |
| --help | Displays usage information. |
| --pmpolicy | Verifies that Privilege Manager for Unix policy is in use by the policy servers. |
| --primary | Verifies a primary policy server. |
| --secondary | Verifies a secondary policy server. |
| --verbose | Displays verbose output while checking the host. |
|
--version |
Displays the Privilege Manager for Unix version number and exits. |
