Because of security issue in NTP (CVE-2014-9295) I need to update NTP-deamon on a Debian Squeeze (it is the Proxmox 2.x installation). The problem is that it is a productional system and I can not test the update commands on a test system. So, I need to know clearly how to update this system. I am very thankful to people who help me.

If you don't have a test system, then make one for yourself:
- Install Virtualbox, VMware Workstation, etc. on your workstation.
- Install a Debian Squeeze server within #1 so that its configuration matches production. (You're using configuration management, right?!? So this should be really easy)
- Take a snapshot of the VM.
- Test upgrading. If upgrade fails, revert to the snapshot and try again.
That's really all you need to do.

Sorry, but you need one. Advocate for yourself. Virtualbox is free. You *cannot* call yourself a professional sysadmin if you are unable to do this sort of rudimentary testing. – EEAA Dec 22 '14 at 05:52
