I have admin rights at a remote Mac computer. I can access it via SSH. The Mac has another user account, which doesn't have remote access. How can I remotely (via SSH) enable remote access for the other account?
SSH access by users is controlled by the local copy of Directory Services. (Controlled using
First off run
dscl . list /Groups | grep 'access_ssh'. If the returned value says
com.apple.access_ssh-disabled then all users have SSH access. If not, then we need to give the user access.
To add the user you need to run:
sudo dscl . append /Groups/com.apple.access_ssh user USERNAME
(replace USERNAME with the short username of the user) as well as:
sudo dscl . append /Groups/com.apple.access_ssh groupmembers `dscl . read /Users/USERNAME GeneratedUID | cut -d " " -f 2`
(replace USERNAME with short username as well)
(The last bit is thanks to Reed Stoner on lists.apple.com)
To add/enable Remote Management for only specific users (Add VNC flags from ghoppe's answer if you want VNC):
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -activate -configure -users short,usernames,seperated,by,commas -access -on -restart -agent -privs -all -allowAccessFor -specifiedUsers
Find out more by running
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -h
Based on Chealion's answer, I came up with this to allow ALL users to ssh in:
dscl . change /Groups/com.apple.access_ssh RecordName com.apple.access_ssh com.apple.access_ssh-disabled
Enable Remote Desktop via command line:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -activate -configure -access -on -clientopts -setvnclegacy -vnclegacy yes -clientopts -setvncpw -vncpw mypasswd -restart -agent -privs -all
Turn off screen sharing:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -deactivate -configure -access -off
OK, I may have misunderstood your question. By "Remote Access" I presumed you meant remote desktop, but now I see you just want to enable ssh access for the other account, right?
My answer gets you halfway there. After enabling Remote Desktop as shown, then connect with the remote Mac to change the user's ssh access via System Prefs.
To connect to the remote Mac, go to the Finder and select
Connect to Server… under the Go menu. type in the Server Address for your computer:
Where x.x.x.x is the remote computer's IP address or URI. Since you connected with ssh, I presume you already know this.
Now you can use the Remote Desktop to navigate to System Prefs > Accounts and click the box to allow the other account to log in to the computer…
ssh access is granted to members of the
com.apple.access_ssh group. This is the group that you're editing when you make access modifications to the Remote Login service through the Sharing pref pane.
dscl can be use to edit group memberships (as described in other answers),
dseditgroup is a cleaner way to modify the
com.apple.access_ssh group memberships from the command line.
to add a user:
sudo dseditgroup -o edit -t user -a USERNAME com.apple.access_ssh
to remove a user:
sudo dseditgroup -o edit -t user -d USERNAME com.apple.access_ssh
