hi... if i understand your question... you want to remotely access your machine, by "tunneling" through your firewall/security.. if you have access to your firewall/security apps/devices, you can setup SSH to run on your box as a secure channel. you of course would need to then setup a SSH client on your client box. this would permit you to run apps on the target system in a secure manner... if this is what you're talking about, you can find out about SSH by hitting "google" as well as the Redhat/Linux site... if you're looking for something else, let me know... -bruce -----Original Message----- From: security-discuss-bounce@xxxxxxxxxxxxxxxxx [mailto:security-discuss-bounce@xxxxxxxxxxxxxxxxx]On Behalf Of S.
