Re: Script for a CVS only shell available?

[Julien Wajsberg]

Another simple way is to use some features of SSH and the authorized_keys
file.

You can use the  « command="command" » option of this file
(see man 8 sshd for more information)

man's extract:
     command="command"
             Specifies that the command is executed whenever this key is
used
             for authentication.  The command supplied by the user (if any)
is
             ignored.


Hope this helps :)

I do not recommend use of rsh. It would be better if you could remove it
from the system... although I understand that this is not always possible.

Try doing 'mak rksh' on your system. If you don't have it, then use your
favorite search engine to find out about it.

If you are using ssh, then you may find the following blurb of interest.
It was posted to the openssh-unix-dev mailing list.

...
| rssh is a restricted shell which allows system administrators to

| For more info, visit the rssh home page:

I have not used rssh myself and I am not advocating its use, I am just
trying to show you where to find the wheels that exist.

Finally, you could always ask sourceforge.net what they are using. :-)

             Good luck,
