If this is a home user and a VPN is out of the question: To get around the dynamic ip addressing, you can create a dynamic dns account (http://www.dyndns.org/) for the user and install a dynamic dns update utility on the remote computer (http://www.dyndns.org/support/clients/dyndns.html). Then, install your remote control software (VNC, PCAnywhere, etc.) on the user's computer and connect to it via the newly created dns account, i.e. homeuser.homeip.net. This isn't the most secure way to do this, but it does work. You can also use an ssh server on the client's pc along with a dynamic dns account to give a more secure connection to the client. To do so, install an ssh server (http://www.openssh.org or http://sshwindows.sourceforge.net/) on the client pc and configure it. Then, from the pc that you want to access the client from, you can use putty (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) or any other ssh client to create a tunnel to the client while using port fowarding to connect to the client. For example, you can forward your local port xxxx to connect to the port running your remote control server on homeuser.homeip.net. Then, use your remote control client and connect to localhost:xxxx and it will forward your request to the correct port on the remote server using the tunnel you created. I hope that helps.

But later rejected by team leader, As said not practical for user to get into our LAN Because we may not know that what is installed or running in the client.

That's what DNS is for. That said, a VPN is your best option. Then you can use VNC, Remote Desktop, etc....after the user has authenticated to the VPN. -----Original Message----- From: hartmann [mailto:hartmann () thestar com my] Sent: Monday, March 14, 2005 7:46 PM To: security-basics () securityfocus com Subject: Any remote client - without fixed IP Hi, Is there any software or any way that we could have a remote control over client(s) Which does not have fixed IP? I'm one of my company system administrators, and currently we need to support remote site clients. But, the difficult part is that the client have a dynamic IP. Thus, is there any tools to help? Even it needs to be launched from the client side. Thanks.
