NOTE

This manpage is a short description of GNU rush. For a detailed discussion, including examples and usage recommendations, refer to the manual GNU Rush -- a restricted user shell, available in texinfo format. If the info reader and the rush documentation are properly installed on your system, the command

info rush

should give you access to the complete manual.

You can also view the manual using the info mode in emacs(1), or find it in various formats online at

http://www.gnu.org.ua/software/rush/manual

If any discrepancies occur between this manpage and the Manual, the later shall be considered the authoritative source.

DESCRIPTION

GNU rush is a restricted user shell, designed for sites that provide limited remote access to their resources, such as svn or git repositories, scp, or the like.

Upon startup rush analyzes its command line and examines the set of configuration rules to determine what kind of access the user is to be granted.

OPTIONS

−d, −−debug=NUMBER

Set debugging level. The greater is the NUMBER, the more verbose is the logging. The debugging information is reported via syslog(3) using authpriv, priority debug. Maximum meaningful value for NUMBER is 3.

−D, −−dump=ATTR[,ATTR...]

Request dump mode. Arguments are the names of the attributes to be dumped, or the word all standing for all attributes. Refer to the GNU Rush manual for a detailed description.

−t, −−test, −−lint

Run in test mode. When this option is given, the following occurs:

1.

All diagnostic messages are redirected to standard error, instead of syslog.

2.

If a single non-option argument is present, it is taken as a name of the configuration file to use.

3.

The configuration file is parsed. If parsing fails, the program exits with the code 1.

4.

If the −c option is present, rush processes its argument as usual, except that the command itself is not executed.

−u, −−user=NAME

Supplies user name for use with −−test.

−c COMMAND

Execute COMMAND.

−C, −−security−check=CHECK

Add or remove configuration security check. The argument is one of the following:

all

Enable all checks.

owner

Check if the file is owned by root.

iwgrp, groupwritablefile

Check if the file is not group writable.

iwoth, worldwritablefile

Check if the file is not world writable.

dir_iwgrp, groupwritabledir

Check if the directory where the file resides is not group writable.

dir_iwoth, worldwritabledir

Check if the directory where the file resides is not world writable.

link

Check if the file is not a symbolic link to a file residing in a group or world writable directory.

−i

Emulate interactive access. Use this option to test whether and how does your configuration allow interactive access.

−−show−default

Show default configuration.
