Pri­vate prob­lem

Mac Format - - APPLE TALK -

My home work­sta­tion is a mid-2011 iMac (3.4GHz In­tel Core i7 with 24GB of RAM). I of­ten work abroad and use my iPad on an un­trusted (public) net­work, I use a com­mer­cial VPN for se­cu­rity, but I’d pre­fer to host my own VPN and rely on my iMac to re­lay web pages to me via it. I know OS X Server 4.1, con­tains a VPN mod­ule. Could I surf the net through it, and would I still be able to use the iMac as a per­sonal work­sta­tion? Mark Dea­con

Chris­tian Hall says… Af­ter in­stalling OS X Server on a Mac, you can con­tinue to run apps as nor­mal. Server is sim­ply used to set up and man­age ad­di­tional ser­vices that run in the back­ground, such as the VPN. These take up ad­di­tional re­sources, such as CPU cy­cles, mem­ory and net­work band­width; the Server app in­cludes graph­i­cal tools, sim­i­lar to the one at the bot­tom of OS X’s Ac­tiv­ity Mon­i­tor app, that in­form you about short- and longterm re­source use. How­ever, your iMac’s spec­i­fi­ca­tions are easily suf­fi­cient to do some­thing as rel­a­tively un­de­mand­ing as rout­ing web traf­fic to one iPad.
