Here’s a quick write-up describing how to connect to your Mac at home from your Mac at work (or any other Mac…).<\/p>\n

Prerequisites<\/span><\/strong><\/span><\/p>\n

1) User access with administrator\u00e2\u20ac\u2122s rights<\/strong> <\/span>on your remote OS X computer.<\/p>\n

2) An Secure Shell (SSH) client<\/strong> on your local computer. On Windows,\u00c2\u00a0Putty<\/a>is a common and free version.\u00c2\u00a0Linux<\/a> and MAC OS X, by default, come with\u00c2\u00a0SSH<\/a>.<\/p>\n

3) A VNC viewer client<\/strong> on your local computer.\u00c2\u00a0 In our case, we’ll using Screen Sharing. You won’t find it in the finder; it’s hidden here:<\/p>\n

\/System\/Library\/CoreServices\/Screen\\ Sharing.app<\/pre>\n
4) Network access to the SSH service<\/strong> on your remote machine.\u00c2\u00a0 This requires<\/span><\/p>\n
a)\u00c2\u00a0 You know your remote machine\u00e2\u20ac\u2122s hostname or IP address.
\nb)\u00c2\u00a0 Being behind the firewall, having VPN access, or being accessible to the public Internet (i.e. no firewall).<\/p>\n
How to Remotely Turn On (and off) OS X Screen Sharing<\/h3>\n
This procedure keeps security in mind.\u00c2\u00a0 The idea is to turn on screen sharing while you need it, and then turn it off when you\u00e2\u20ac\u2122re done.<\/p>\n
1)\u00c2\u00a0 SSH into your remote OS X machine<\/strong> with an administrator\u00e2\u20ac\u2122s log in and password.<\/p>\n
2) Enable Remote Desktop<\/strong> (a.k.a. Screen Sharing, a.k.a. VNC) with this command:<\/p>\n
sudo \/System\/Library\/CoreServices\/RemoteManagement\/ARDAgent.app\/Contents\/Resources\/kickstart -activate -configure -access -on -clientopts -setvnclegacy -vnclegacy yes -clientopts -setvncpw -vncpw password<\/strong><\/span> -restart -agent -privs -all<\/code><\/p>\n
3) Login using a VNC client.<\/strong> You can use Screen Sharing or Chicken of the VNC (see tip below).
\nYour password is \u00e2\u20ac\u0153password<\/strong><\/span>\u00e2\u20ac\u009d (see the -vncpw flag in the above command;\u00c2\u00a0 you can \u00e2\u20ac\u201d and should \u00e2\u20ac\u201d change this).<\/p>\n
4) When you are done, turn of screen sharing<\/strong> using your SSH session:<\/p>\n
sudo \/System\/Library\/CoreServices\/RemoteManagement\/ARDAgent.app\/Contents\/Resources\/kickstart -deactivate -configure -access -off<\/code><\/p>\n

\nProblems connecting with your VNC client, like Chicken of the VNC?<\/span><\/p>\n
Set your remote display settings to greyscale (to speed up things) or ‘Let server decide). Anything lower than ‘thousands’ won’t work.<\/p>\n
