Hi List, I have a very peculiar problem about accessing VNC server behind gateways and proxy server... Here is the background info... I have a client who has pretty big vnc installation base mostly windows but Linux and Solaris also includes. Most of the Road Warriors have windows with vnc and ssh installed on them ( mostly winxp sp2 ) VNC is used to remote admin or support for some of the road warriors. But most of the times when the VNC server is behind a gateway like this it wont connect. [ Internet ] -- [ Gateway ] --- [ Lan ] The work about is to use the UltraVNC relay service, but if you don't have any control over the gateway this becomes impossible to operate. And I hate to open ports in the firewalls of the road warriors' computers. Is there a way something like reverse shell that allows someone to connect to a VNC server, behind gateway and through firewalls without opening any holes in it or a tcp/ip proxy that is proxy that does not allow connections from the internet ? Basically, The user initiates the connection and the helpdesk can use the same socket to the laptop for connection over VNC ( vnc encryption and compression have already been taken care of, and only one socket is needed for all this- for a firewall I would require only one hole ) Any help would be appreciated - aditya ________________________________________________________________________ Delivered using the Free Personal Edition of Mailtraq (www.mailtraq.com) _______________________________________________ Full-Disclosure - We believe in it.
