![]() Sugar is a learning platform designed for children. Looking past the hardware, one of the key features of OLPC deployments is its software-more precisely, its software as a learning platform. And I am slowly making my way through the somewhat annoying “Program or be Programmed” book by Douglas Rushkoff.Īs I bang my head against one typical make-it-work for education problem after another, Sugar and the title of Douglas’ book keep coming to mind. Last week I read the Linux Journal article “OLPC: Are We There Yet? An update on the One Laptop Per Child Project.” by Sameer Verma. I am still investigating how this happens and will update the post when I know. ![]() Unfortunately this group is not created until the GUI is changed to “Only these users”. The group appears to be /Local/Defaults/Groups/_ssh, which can be read using the dscl command: sudo dscl. sshd is configured to use pam.d, and pam.d is configured to use opendirectory for determining which accounts. Limiting which accounts can use sshd is a little more complicated and I am still piecing all the parts together. If you get launchctl list returned unknown response, that means sshd is not loaded. Use sudo launchctl list to see information about the job. You cannot reliably check if remote login is on by running ps aux | grep sshd because this daemon is managed by launchproxy. Sudo -s launchctl unload -w /System/Library/LaunchDaemons/ssh.plist # Turns off ssh ![]() To do the same thing via the command line, you need only run the following: sudo -s launchctl load -w /System/Library/LaunchDaemons/ssh.plist # Turns on ssh You also have the option of limiting who can use ssh to connect to your computer by changing the “Allow access for All users” to “Only these users” and then adding the users and groups who can connect. ![]() With mouse and keyboard, you can enable/disable sshd on Mac OS X by going to System Preferences -> Sharing. This information is all out there, but there is enough cruft mixed in, that I’m making my own post. ![]()
