Remote SSH using Back To My Mac

twitter:description

If you have more than one Mac running OS X Lion and you’re signed in to the same iCloud account on all of them, you can SSH between them via iCloud’s IPv6 network. First, find your Back To My Mac account number by running dns-sd -E Then SSH to another machine like so ssh -2 -6 username@computer-name.[account number].members.btmm.icloud.com That’s hard to remember and a hassle to type, so might want to add something like the following to your ~/.ssh/config: Host mac-remote User username HostName computername.123456789.members.btmm.icloud.com AddressFamily inet6 Protocol 2 Which means you can just type ssh mac-remote to log in to your other Mac when you’re out and about. Very handy. Update 24/07/2012 Reader TJ wrote in to say: If you don’t want to hard code your Back To My Mac address into your .ssh/config you can get it dynamically using this line: echo show Setup:/Network/BackToMyMac | scutil | sed -n 's/.* : *\(.*\).$/\1/p'
