With the death of the Xserve & subsequent killing off of the MacMini server many Mac Admins have either sought to remove all Apple branded hardware from the server room or have been forced to.
Myself? I now look after a total of 25 Mac Servers, 21 of which are dedicated to our JSS & are installed across 8 different sites globally, some of the challenges of which are touched upon in the JNUC2014 Panel I was on, titled Thinking Big: Scaling JSS Infrastructures for the Mobile Workforce.
The focus of the post below is the Mac Mini’s which are used onsite for Casper Suite Distribution Points, NetBoot Servers & Caching Servers.
I use RSYNC over SSH & launchagents to keep my Casper distribution points in sync with the Master.
However on upgrading the master to 10.8.2, the SSH connection would error with the message:
“Permission denied > (publickey,gssapi-keyex,gssapi-with-mic,keyboard-interactive)”
I re-ran through the steps i’d used previously.. reached out to JAMF support, JAMFNation & the MacEnterprise Mailing List.. still no joy..
So, it then started to think that maybe the change in OS for the master meant a change in method.. after Googling “mountain lion authorized_keys” I came across the below blog, with revealed the answer!
