I’ve been trying to restore my JSS 8.73 to a test server in preparation to test upgrading to 9.2x, but during the restore i was getting the error “ERROR 2006 (HY000) at line 1692: MySQL server has gone away” as shown below.

When creating test JSS instances, I often stumble over this issue where the “Change MySQL Settings…” option is greyed out
As mentioned in my previous post, we have a simple cluster setup for our JSS.
However, I’ve seen and intermittent issue with permissions to /var/log/jamfChangeManagement.log, below are more details as well as a break-fix solution.

This weekend our firewalls were replaced with us moving from one vendor to another. This took a little longer than required due to some issues with rules & inside outside definitions, but my colleague was more than up to the challenge.
This change required our VPN config profile to be re-pushed, it seemed to work. But further testing revealed we had an issue.
We have a simple cluster for our JSS with one server “cloud” accessible in the DMZ & another on our WAN that is our master JSS, post firewall change I checked:

Infrequently we’ve been seeing the below error on some iDevices after enrolling into our MDM solution.
“Cannot Get Mail. The connection to the server failed”
Plugging those devices into a computer running iPhone Configuration Utility would reveal the following errors in the logs.
“The operation couldn’t be completed. (DAErrorDomain error 111.)”
Realising we had maybe a more Exchange side issue, we looked at the logs on the Exchange Server we were connecting to.. these logs contained the following errors:

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!

I started getting the above error when launching Casper Admin & Remote on my main mac.
This error would appear when launching Casper Admin & Remote, before i could enter any credentials. Which got me thinking: keychain!!
Yep sure enough, I had a saved password in my keychain.. once i deleted that all was well.
When trying to setup a clustered DMZ server as a computer only JSS I received the below error:
Could not write to /Library/JSS/Tomcat/webapps/ROOT/WEB-INF/web.xml
To resolve I needed to enable change management in the JSS. But as the JSS did not have write permission to /var/logs/ I couldn’t enable change management.
So I changed the log location & enabled change management. I could then enable the JSS instance as computer management only version.
Recently we setup a 10.7 Mac Server in our DMZ & clustered this with our main JSS to enable external clients connectivity to our JSS & for them to be able to use Self Service & ASUS when off the network.
However we’ve had some issues getting the distribution point to work over HTTPS, however HTTP & AFP worked fine.
Below are some details on the steps taken to investigate this issue, and resolve.
