+====== Remote installing of a ubuntu linux server ======
+===== The problem =====
+The problem is to install a linux server without touching the system. Ok, ok, I at least need that someone enters the CD into the linux box, but this is all I would need. The idea behind is that in on today's datacenters, physical access is complicated, or even impossible: you have to contract "remote hands" in order to make simple things that can't be done remotely.
+===== VirtualBox on the rescue =====
+Of course, I've started with a virtual linux installation to see how it is done. You have to use the "bridge" network adapter in order to access remotely to the machine, because it gives a real IP of your local network, and so the virtual computer will be accesible through internet.
+In the virtual machine there should be mounted a CD (or an ISO image) of the new server.
+Log into the machine with ''ssh -X'' and mount the CD:
+<code>
+root@ubuntu:/media# mount /dev/cdrom /mnt/
+mount: block device /dev/sr0 is write-protected, mounting read-only
+</code>
+And run ''cdromupgrade'':
+<code>
+rluna@ubuntu:/mnt$ sudo ./cdromupgrade
+Checking package manager
+Continue running under SSH?
+This session appears to be running under ssh. It is not recommended
+to perform a upgrade over ssh currently because in case of failure it
+is harder to recover.
+If you continue, an additional ssh daemon will be started at port
+'1022'.
+Do you want to continue?
+Continue [yN]
+</code>
+Answer yes, of course. The process of install will start. Answer the questions as usual:
+<code>
+To continue please press [ENTER]
+Reading package lists... Done
+Building dependency tree
+Reading state information... Done
+Building data structures... Done
+[....]
+</code>
+After the process, the machine reboots effortessly, so it can be done this way.
