If I clone a debian linux from a server to a harddisk, can I simply plug this clone harddisk to another server and boot it up to use as the primary OS disk for this server, even though the 2 servers may not be the same configuration, same make and model?
View 2 RepliesI'm planing to get 4 dedicated, remote servers for my start up, the question I have is: how to do only one installation and then duplicate or clone this installation into all the other machines. I could install those 4 servers manually, but the problem is - we have a lot of things that our application needs, and later there will be more servers. So an automatic way to do that would be better. We are using Debian. Perhaps there's a way to create a "big package" that will contain all of the necessary software in it, then simply require from the hosting provider that all of our servers come with Debian installed, and then manually upload the "big package" and install it?
View 3 Replies View RelatedI have a bunch of computers with the same configuration, so I would like to install Ubuntu only to one master computer and later on just copy the partition layout and the filesystem unto other computers. Previously I was able to simply copy the partition layout (via the sfdisk utility), the filesystem (a simple "cp -a") and install Grub (via script). Now I had to use the parted utility to partition the 2TB drive and Grub2 is the default boot loader.
My questions are now:
1. How do I copy the partition layout from /dev/sda (master) to /dev/sdb (clone)?
2. How do I batch install install Grub2 to the other disk (e.g. /dev/sdb) ?
In Grub 0.97 it used to be something like that:
Code:
# GRUB the disk
grub --no-floppy --batch <<EOF_GRUB
root ($GRUB,0)
setup ($GRUB)
quit
EOF_GRUB .....
In Grub 2 I tried with:
Code:
grub-install --force --root-directory=/mnt/sdb1/ /dev/sdb
Only to get this error: .....
The Grub2 syntax is way different compared to Grub0.97. Yes, I do could use the Grub2-suggested option but since the partition layouts on both partitions are equal, I see little point in setting the BIOS Boot Partition option, since the master computer works without it and I don't remember any error message during the install.

View 1 Replies View RelatedI will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
Running Squeeze here. I added a new SSD to my system. Root is /dev/sda3 and I want to clone that system to the new SSD on /dev/sdb1 and make it bootable. I tried:
mount /dev/sdb1 /mnt/ssd_root
cp -dpRx / /mnt/ssd_root
then
update-grub
or
grub-install --recheck --root-directory=/mnt/ssd_root /dev/sdb
but to no avail. I cannot get the new system to be bootable and available through Grub. Part of the problem is that I do not know my way around Grub v2 so well, I could probably manage quite well with legacy grub. So, whats the easiest way to clone a system and make it bootable on another partition? Should I be using debootstrap, and importing/exporting the package list to install the same packages on the new system as the old? or is using cp -dpRx to copy the old ok? How do I make the new system boot?

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.

I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I have 2 computers on the same network that i need to link together to transfer files 1 is a web server the other is a minecraft server. the problem is that the file transfer will be constant as the minecraft server will constantly updates files on the web server and I dont want it to go to the router then to come back to the web server. I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?
View 2 Replies View RelatedI am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:

View 3 Replies View RelatedI am completely new to Debian . My aim is to get one of my machines to run this system as the intranet server including www server, mailing server, intranet server and LAMP at the same time on the small network. I have found some resources including how-to's how to install Debian as the normal operative OS not as the intranet server. I have also found this: [url].However that is applicable for the 'Mandrake' distribution (Mandriva). Now, I would like to ask few questions that will be applicable not only for me but for more users and if someone could answer them .
1.What installation source shall I choose, CD/DVD/Network Install CD?
2.I have found this: [url] ... troduction is that applicable?
3.How to install web server, mail server, LAMP and configure them, link above describes mail server installation not configuration itself.
4.How to configure intranet on Debian to work as the server serving the Windows clients (using Samba?)
If someone could propose a set of the sources or the instructions how to achieve all of the steps I would really appreciate that. Also, if sources will be given by the users I shall try to achieve what I want and write up 'how-to' for this problem. Therefore, me and other users would benefit from that.
I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.
My current setup as it is now :
The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.
Now my setup as it is now :
So now what i ment to do was :
Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.
But now i have two huge problems :
1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.
2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.
