Score:5

Updated: Do you ever get exposed to supportconfig files from servers that do not have access to update repositories? Or do you find it difficult to relate to patch numbers of updates (not) installed in updates.txt of a supportconfig?

If so, how do you easily find out if there are pending updates available from SUSE/Novell to be installed on the system to make it up to date?

Exactly – you don’t.
Until now…

This article describes how to discover the ESX version when we have only access to the VM guest.

Me: “I cannot get to your site.” Helpdesk: “Hmm, let me check. I can ping it, so it must be okay.” Me: “No, pinging has nothing to do with access to the site.” Helpdesk: “No, you’re crazy, I can ping it so it’s your problem. Goodbye.” If you have never had this type of exchange with others, you’re lucky.
