You might try a Hamachi VPN setup (free if you only connect a limited number of computers). Allows file sharing as well as screen sharing. You might consider an Apple MobileMe subscription and the Back-to-My-Mac feature. You might consider secure (free for screen sharing, but you pay for the ability to transfer files). You might consider (free for personal use). I think this is secure, but I am not positive. That is to say, enable "Encrypt all network data" will be secure. That should make sure that neither the username/password exchange nor any of the screen sharing data should be visible to anyone except each end of the connection.
Maybe even some special characters in the mix, and make it long (a phrase you can remember with some numbers in obvious substitutions is better than a short password).Īgain, after making your first Screen Sharing connection, go to Screen Sharing -> Preferences -> Encrypt all network data (more secure). Upper and lower case, letters and numbers.

So again you are left with your password as your line of defense.īottom line. If you did not enable "VNC viewers may control screen with password" and are depending on Username and Password, then a guessing your username is easy if they know you, as it tends to be a combination of your first and last name. The good news is that most attackers can not get that, but it is much less secure. Also this form of connection is not encrypted, so if they can monitor your traffic, then they can get the "VNC viewers may control screen with password". That just means the attacker only needs to try brute force password attempts. If you enabled System Preferences -> Sharing -> Screen Sharing -> Computer Settings -> "VNC viewers may control screen with password" then you do not need a Username. There are bot networks that probe "ALL" IP addresses, and make connection attempts against standard ports (port 5900, 5901, 5902. Is that secure enough, or are the other precautions I should take? You will have to find out what range of addresses your routers assigns via DHCP.ģ.) How secure is this really? In order to connect to one of my macs, a remote user would need my router’s WAN IP address and each computer’s username and password.
For example if your router assigns 192.168.1.2 through 192.168.1.100 as DHCP addresses, you could assign fixed IP addresses to your Macs starting with 192.168.1.101. If not you could switch to using fixed IP addresses, picking addresses just outside the router's DHCP address range. Some routers have the capability to capture the MAC (media access control) Address and always give the same DHCP address each time the Mac connects. Will my router keep track of the new IP address, or would I have to constantly reset my router’s settings for the new address? You are more likely to run out of Macs at home then port numbers you can use.Ģ.) All my macs are currently configured using DHCP, which I believe resets the IP address upon startup. And the vnc://router.address:5901 does not care about the port number following the colon (as in :5901). The router, for the most part, does not care about the port numbers, and since it is renumbering from 5901 to your Mac's 5900, the Mac doesn't know that you are renumbering. 1.) is there a limit to how many computers I can have set up (ie: can I keep going to port 5903, 5904, 5906, etc.
