Is There A Access Software Between The

To figure out which remote access alternative is right for you, you need to consider a few different features.

According to a recent study, two-thirds of the U.S.

Macs have more than one computer.

Nearly three quarters of those households have laptops as well as desktops.

A significant number of those Mac households also own iPhones, iPads, or other iOS devices.

Combine those numbers, and you have a lot of Mac owners who need to connect from one computer (or iOS device) to anotherwhether that other computer is down the hall or across the country.

They need not only access to files on other machines, but also the ability to control the remote machine and run apps on it.

They might want search through an e-mail archive, start a backup, or use a database thats stored only on that other machine.

In the home, they might want to control a Mac mini-based home-entertainment server that has no monitor of its own.

If you need that kind of access, chances are you already know all about it.).

Unfortunately, its not always easy to figure out which one of those options will best meet your specific needs.

And even if youve settled on a solution, its not always easy to get it to work.

Remotely controlling one Mac from another within the same local network isnt especially difficult; Bonjour and other networking tools do a good job of that.

Controlling a machine on a remote network is trickier; much of the networking hardware and software between the two is set up specifically to keep that from happening.

Home networks typically use a combination of two technologiesNetwork Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP)to provide Internet access to multiple computers through a single Internet address and to provide a light (not robust) buffer to keep strangers out of the network.

DHCP assigns private network addresses to the local computers.

NAT then rewrites those addresses at the router, so that, to the rest of the Internet, all the traffic from those multiple computers seems to be coming to and from just one publicly accessible address.

Some remote-access tools (particularly dedicated remote-access services such as Back to My Mac, GoToMyPC, and LogMeIn) take care of this problem by talking directly to a routers NAT software and then mapping specific pathways into the network.

Other solutions (including OS Xs built-in Screen Sharing software and VNC) require you to set up port mapping.

If IP addresses are like street numbers for apartment buildings, ports are like individual apartments at those addresses.

A port is assigned to a particular service, such as file sharing or outgoing e-mail.) That means establishing persistent connections between ports on the routers Internet-facing IP address and specific computers inside the network.

If youre lucky, NAT-PMP (NAT Port Mapping Protocol, favored by Apple) or UPnP (Universal Plug and Play, common on non-Apple hardware) on your router can take care of the port mapping for you.

Third-party software such as Port Map ( ) or Lighthouse can also do the trick.

Another program, ShareTool ( ), can create persistent connections between local networks, allowing for standard Bonjour hook-ups.).

There is another workaround for gaining remote access: Dynamic DNS lets you map a human-readable domain name, like remote.mymachine.com to your routers public IP address.
