Monitoring disk drives via collectd

April 17th, 2012 No comments

I’ve made two simple (but useful) disk drive monitoring scripts for collectd exec plugin. You can find them on http://devel.dob.sk/collectd-scripts/.

smartmon.sh

This script monitors SMART attributes of given disks using smartctl (smartmontools).

megamon.sh

This one monitors some interesting values of MegaRaid adapter physical drives using MegaCli tool.

 

Description how to use them can be found within scripts itself – enjoy ;)

windows – exporting non-exportable private key

April 5th, 2012 No comments

If you are trying to export windows certificate with private key, and windows export wizard provides no such possibility (export with private key is grayed out) because private key has been install as non-exportable (what is the default when importing, what almost nobody changes), there is a great tool mimikatz that makes this possible.

Download it from http://blog.gentilkiwi.com/mimikatz.

And follow this procedure:

  1. crypto::patchcapi (or crypto::patchcng if previous did not work)
  2. crypto::listKeys (or crypto::listCertificates) to list keys/certificates
  3. crypto::exportKeys (or crypto::exportCertificates) to export what you want

That’s all. Exported keys will be protected with password ‘mimikatz‘ – you will need to enter it when importing certificate again.
