I always forget, and this blog is meant to help me remember.
Found in Tar’s manual, are these simple directives:
Have a file called file.tar, do:
tar -xf file.tar full/path/without/trailing/slashes

tar -xf file.tar home/me home/you home/us/important-file

One of the worst things you can have in XenServer, is some wize-guy performing a ‘forget storage’ on a storage device still holding virtual disks related to VMs. As XenServer database is internal (for the whole pool) and not per-VM, all references to this virtual disks disappear, and you remain with bunch of VMs without…
Assuming your storage is capable of replication, a bunch of VMs could be happily replicated to an alternate location, where you can start them on will (and on crisis, most likely). This procedure, in theory, is rather simple. I have discovered that it is less so, especially if your system goes into testing once a…
The idea in general is to have multiple wireless networks at home – one for the house residents, the other for visitors. The home network should have full access to everything, while the guest network should be able to reach the Internet, but nothing else. I have Asus RT-AC87U, which is a fine router, but…
Here’s a little issue. If you were to replicate MS Exchange DB from one machine to another, how/what would you have done? The scenario goes as follows: You have your own domain, and you use, for your own core services AD and MS Exchange for the whole organization. While AD supports some built-in replication, so…
I was required to write a small listener. This listener doesn’t have to do anything fancy – it has to process input from a network source (over TCP) and shove it into a file with random name. The quick and dirty solution is to use netcat (nc). A short command such as this would do…
I have an old Dell server (R610, if it’s important) and I seem to fail to connect to its iDrac console via Java. No other options exist, and the browser calling Java flow fails somehow. I have found an explanation here, and I will copy it for eternity 🙂 First – Download the latest JRE…
