In some cases we’d like to know, how much has been sent by our Postfix server on a per account basis.
Server consolidation ratio grows steadily. But how can we migrate our current systems to a virtual environment in an easy way?
Besides vendor specific solutions, for Linux systems there’s a simple and quick way to migrate a server to another machine (in most cases to a VM)
Getting through the steps you can set up a stable VPN connection for any of the following situations:
- I don’t live in the hostel, but would like to play LAN games with friends 🙂
