SSH - prevent roaming around the server
Hi,
We have a user who needs to connect to us over the internet using an ssh client. We use HP-UX 11.00.
We set up a home directory with login and password for them. We would not want to give them full roaming access for the server ie, they should not be able to cd up the directory tree.
We have found that if they connect with ftp, they do not have roaming access. However, if they connect with ssh/sftp, they do have full roaming access.
Can anyone tell me how to stop them cd'ing out of their home directory up the directory tree when using ssh/sftp?
Many thanks
Helen

gnome-ssh-askpass
GNOME-SSH-ASKPASS(1) General Commands Manual GNOME-SSH-ASKPASS(1) NAME
gnome-ssh-askpass - prompts a user for a passphrase using GNOME SYNOPSIS
gnome-ssh-askpass DESCRIPTION
gnome-ssh-askpass is a GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not invoked directly. It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display is available). This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro- grams, for example. In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass. ENVIRONMENT VARIABLES
The following environment variables are recognized: GNOME_SSH_ASKPASS_GRAB_SERVER Causes gnome-ssh-askpass to grab the X server before asking for a passphrase. GNOME_SSH_ASKPASS_GRAB_POINTER Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase. Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab(). AUTHOR
This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others). It was based on that for x11-ssh-askpass by Philip Hands. GNOME-SSH-ASKPASS(1)
