I have been searching for simple and easy script to backup selected virtual machines running on esxi server, which will:

run on linux – do not require windows machine; can’t use PowerCLI
do not require direct access to esxi host using ssh (as other backups scripts like ghettoVCB.sh do) and will use API
support multiple esxi hosts managed by vcenter
have clear code – that means no perl hell (including big vsphere perl sdk)
have short code
can be put into cron

I was unable to find any to comply my requirements. I’m learning python, so I searched for some python vsphere libs and found psphere. Then backup.py has born.

There are many sites providing country blocklists, for example http://www.ip2location.com/free/visitor-blocker or https://www.countryipblocks.net/. When you want periodicaly update such list, you have problem. You need pay for that service for automated access, actual data or “hack” access to that service (abuse their free access conditions)…

Everyone know common dns blacklists used for rejecting emails. To check, if ip address is blacklisted on some blacklist, it is common to use service like mxtoobox.com. But what check next, if mxtoolbox shows ip is not blacklisted and email or connections are still rejected (sometimes without any reason) by some servers?

I have been searching log time for tool which can convert HD Windows Media Center recordings (wtv format) to some playable format for Samsung TVs, which are unable to play WTV recordings. I want to do it without re-encoding original wtv file. Finally I have found great tool remuxTool (v1.2.5). It’s java application, it has gui or can be used in command line, which I prefer.
