restricted user shell
GNU Rush is a restricted shell designed for sites providing only limited access to resources for remote users. The main binary executable is configurable as a user login shell, intended for users that only are allowed remote login to the system at hand.
A notification service can be implemented individually for each provided client service, using the TCPMUX support found within xinetd, or inetutils-inetd.
The standard use is to create access to a chrooted target directory, typically providing arbitrary combinations of scp, sftp, rsync, cvs, svn, and git. Each service may be further restricted in its capabilities. The administrator configures pattern matching rules for manipulating any incoming request.
The present restricted shell is an alternative to the well known "rssh" package, which provides similar capabilities.
