Here’s an easy way to update the OpenELEC running on a CuBox-i easily:

cd ~/.update curl http://snapshots.openelec.tv/`curl http://snapshots.openelec.tv/ | grep OpenELEC-Cuboxi | cut -d\" -f2` | tar x mv OpenELEC*/target/* . && rm -r OpenELEC* |
Well, I’ve been playing around with PowerShell today. I had the task to move (as in change the IP address) two domain controllers into another VLAN. I could have done it the easy way and added the DNS servers by hand (by RDP’ing to each system having these particular DNS servers configured) – which wouldn’t have been very hard considering the domain only has 7 members at this point …
I wanted to do it the proper way, so I ended up asking old uncle Google, and it supplied me with the answers I was looking for.

PS > Get-ADComputer -SearchBase ` 'OU=Server,OU=Devicesdc=ka,dc=home,dc=heimdaheim,dc=de' ` -Filter '*' | Select dnshostname | foreach { >> Invoke-Command -ScriptBlock {Get-NetAdapter -Name Ethernet | ` Set-DnsClientServerAddress -ServerAddresses ("10.76.15.20", "10.76.15.20", "10.75.20.20", "10.75.20.21")} ` -ComputerName $_.dnshostname >> } |
Now, I executed those few PowerShell lines before changing the IP address of both domain controllers (10.76.15.20 being the old IP and 10.76.20.20 being the new one). After that I changed the IP address on the second (and after a short downtime) on the first domain controller. After both were restored and available again (and I checked with repadmin /showrepl), I ran the script again, this time only setting the new DCs:

Well, considering the time I spent on looking for this and the time I would have needed to change even the seven members – even this is a time saver.
