-====== 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.
