Ubuntu Installation :: Network Settings When Cloning To Identical Hardware?
Aug 9, 2010
The company I work for use Ubuntu on the PC's that control the system they manufacture. To simplify and speed up the OS install we use a standard PC (all the same hardware) and install a disk image on each system. The disk image was produced from one of the systems and the network settings were set to use a Static IP
However every time we clone a system the network settings change from the static IP settings to Roaming Mode.
why this happens or if it is possible to have the static IP settings remain after the clone?

I had problems with the system not reading the monitor EDID and have fixed the problem by adding an override file in xorg.conf.d and all of that seems to be working well (although the system has not failed to read the EDID since I implemented the override. go figure).
The thing that I am wondering about is something I see in the Xorg log file. At the end of the log file, after everything seems to be configured, there are six (6) identical blocks of information regarding the EDID and modeline settings. Is this normal or is X stuck in some kind of loop? Everything is working and I am not waiting an inordinate amount of time to log on, or after. Just curious. Here is the log file.

I haven't used linux in a long time, and have to install OpenSUSE 11.3 on ten of our servers. What I plan to do is install OpenSUSE and all our required software on one of the servers, and then clone that drive to all the other server drives (the servers are hot swappable). My question is:
What do I need to worry about conflict wise? So far the only conflicts I can see that I will need to address are machine name (hostname) and set unique static IP addresses? How can I change the machine name (ie. server01, server02 ...) and IP address? Is there any other stuff I need to change as well?
We have a 2U file server running windows. All of the servers (1 x Win and 10 x linux) will be connected to a 24 port gigabit switch.
Is there also any special stuff I need to do to allow access to the Windows server (file etc)?
I will also require remote access to the servers, but assume that this will be easy to setup?
As for sleep mode, I assume that's fairly easy to configure through the interface?

We are giving away 20+ machines to 3rd world county and I was asked from the receiving party to install linux on them. What I don't want is to pop a cd into all of them and do the manually install.
I'm thinking of installing one computer the old fashion way and do the OEM-configuration on it afterwards. It would be nice to just clone the hard drives since the computer is identical right down to the hard drive.

I am setting up 4 laptops that are all the same make and model with 64bit squeeze.What is the best way to setup the master laptop? LVM?
Once the master is all configured how we need, what is the best way to clone it to the other laptops? Once all the laptops are cloned what is the best way to refresh or update the other laptops from the master laptop?

I have a busted XP notebook, no CD, no boot from USB. I have the option of booting from network, my provider wants to charge me to set up a static IP address I'm hoping to just plug in to my working 8.04 install with a cat5 cable or through a simple workgroup switch & get the basics installed where would I find such a procedure?
the gateway notbook hangs, part way through the restore [xp] process, I can only get to bios & restore, no dos prompt I don't care about any of the info or having XP I know the HDD may be bad

I have my Mythbuntu 9.10 environment installed on an old 160GB PATA disk and have just purchased a new 64GB SSD that I want to transfer my installation to.In the past I've just used ddrescue to clone disks, however in this case the source disk is larger than the destination disk so it won't work. I only have a few GB of actual data on the 160GB disk, so the 64GB SSD is definitely going to be enough for me.
I guess I need someway of either cloning so that only the actual data and not the partition is brought across, or possible shrinking the partition(s) first on the source drive and then using the same ddrescue method I've used in the past.Just looking for some assistance on what method is the best/most reliable?

I would like to replace my old 100gb boot drive in my server with a new SSD...for obvious reasons. So what is the best way to clone the existing installation (10.04 desktop) from the old boot drive onto the new SSD? I have read some guides online that suggest using the live CD and various software packages but most of them say it will only work if you are cloning to a disk of the same size or larger, nobody seems to address taking an installation from a larger volume down to a smaller one - in my case a 100gb IDE onto a 30gb SATA SSD.
As this is a datadump, the only drives I really care about are the various 1.0/1.5tb drives that actually store the data, the OS drive contains nothing more than the standard OS, samba/webmin and a few monitoring tools. So I guess it's not the end of the world for me to start fresh and install 10.10 next week, but I would like to know for the sake of this upgrade and future ones if anyone can be of assistance. basic specs if needed: Athlon64 X2 3800, 2gb DDR500, Asus A8N SLI Premium (Nforce 4/Silicon Image 3114R RAID controller). OS is on a 100gb IDE (WD1000BB-00C) and I would like to toss it on a Kingston 30gb SSD (SNV125-S2/30).

I bought an 1tb hard disk today and cloned my old 160gb ubuntu install to the new disk using gddrescue (from this tutorial [URL]) and everything worked fine. The problem is that I can't resize my home partition to fill the rest of the disk. I've tried using a live-cd and booting from my 160gb hard disk but I still can't resize the partition.
Here's the "sudo fdisk -l" output:
Quote:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Basically I have setup and configured a CentOS 5.6 system on one server, and will be getting a brand new server in about a months time I was wondering if there was a way to clone a system from one server to another so I don't have to add all the users again, the config files are not a issue as I can just copy them over, but having to re-do all the user accounts, smb accounts and folder permissions will be a pain.

I have read several manuals and online html on how to clone a partition to a greater one, I am still not sure about what to do.
Code: Select all# df -k /srv /usr
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md5 38445384 195236 36297128 1% /srv
/dev/md3 8648896 1088016 7121540 14% /usr
What is the recommended procedure to clone i.e. /dev/mdx (/usr) partition to a greater one, say /dev/mdy, to accommodate for growth, whilst preserving attributes including timestamps (and yes, that means also including ctime).All of # cp -ax SOURCE DEST, # rsync -ax SOURCE DEST and # cpio modify ctime.Some sites recommend dd, i.e.:
Code: Select all# dd if=/dev/mdx of=/dev/mdy bs=512 conv=noerror,notrunc,sync
URL....However, I am not sure what will dd copy do with end of partition, and will it see the remaining space on /srv (it's contents are dummy and will be overwritten).

is there a way to clone an installation? I have a couple "master systems" which I want to replicate into other servers. In Solaris I can build a flar image from the first one and install from that image, I looked into cobbler and koan, but they seem to be more repo and kickstart oriented.I need a way to say "take this system as a base and build an installation image out of it".

I have used GParted several times but I only know how to clone a single partition. I am looking for a way to clone and entire drive that has several partitions, along withthe MRB, unpartitioned space and everything else in one step. I have a 500 GB drive that is going out and I want to clone it to a 1 TB drive so I don't have to reinstall 3 different OSs and fix the GRUB. One of the other OSs is on anther drive so I'm not sure that it would work even if I can clone everything exactly. I'm not sure if the drive that is failing is the one with the MBR on it or not. how to do this in GParted or know another good program I can run from a live CD to do this?

I just successfully installed ubuntu 10.10 Meerkat Maverik parallel to manufacturer installed Windows 7 Professional on a newly bought ThinkPad t410. All works find just that on the boot screen instead of 1 Windows partition (usually something like "Windows 7 loader on sda1") I find two Windows partitions. Now, I know that Thinkpads have a recovery partition. Funny is though that both "Windows 7 loader on sda1/2" login to what seems the identical Windows (not one of them the "normal" and the other some form of a recovery).

I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.

I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.

I've updated a desktop from 11.1 to 11.2 with the NET CD. After completion everything worked fine, though I have some issues with the NIC. been looking on the net and the provided solutions haven't been able to resolve the matter. After reboot I don't get an IP address, I go into Yast2 and network settings displays:
I have to delete the unknown device everytime after a reboot in order to get a new IP address. After that all works as it is suppsed to. I've been looking into the /etc/udev/rules.d/70-persistent-net.rules and deleted all that was in there,

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.

I have discovered that I have two partitions, on separate hdd's with identical UUID's, and the system switches back and forth erratically on restarts between the two different partitions, giving me the current /home or the /home of two months ago when I did the upgrade.

small non-profit set up an isolated network for a classroom, not connected to the Internet. Most of the computers are old second-hand systems, made usable by running Linux, the one new computer can dual boot Ubuntu and Windows. I think the most light-weight approach would be to use one of the network numbers reserved for private use, assign static IP addresses, and host names in a hosts file, rather than relying on DHCP or DNS, because this wouldn't rely on any servers. But, even so, I expect to have to configure _something_ for the IPs of a gateway and DNS servers when we set up the static IP settings.what would work best for these settings?
The best guess I can make would be to list a real system with a tcp/ip stack that wouldn't be too tightly firewalled, so that requests would get promptly rejected (or handled if there is a trivial way of doing so), rather than timed out. But, I'm looking for more specific advice of what works on practice. (I'm familiar with other flavors of Unix/Linux, and TCP/IP in general, mainly from running applications on servers, but I don't have much experience on Ubuntu.) These systems would be on Ethernet switch, but I don't think we can count on any router appliances. I suppose one of the spare computers could be dedicated as a minimal router. The objective of all this networking is to set up print sharing and perhaps file service, using one of the better computers as a server.

I run a small (cabled) network between a desktop with XP with two printers hooked to it and a laptop with Ubuntu 10.04.1 64b. I can approach and use these printers from my laptop and filesharing works also. BUT ... this only works when my Ubuntu firewall (Gufw 10.04.5) is switched off. I am operating behind my router_modem which has a hardware type of firewall switched on at all times so I presume I'm safe. Now my questions:
1. Is this really safe enough?
2. What kind of settings would Gufw need to be able to use it AND use my mini-network for printing? I have no experience whatsoever with firewall rules and settings.

My first post. I lost all connections to the internet on my Linux Box Yesterday. I have checked my broadband connection and router. OK because I am using them to sent this from my laptop. I have 2 ethernet cards - no indication of a problem with either so I suspect for reasons unknown I have lost all my network settings. The Desktop User Guide says go to the Network Settings Window. I used to have a widget on the Menu Bar which enabled me to check the settings but for some reason it vanished a month or so ago and I can't find how to get it back.
PS In the meantime I am stuck with this crummy Microsoft box the interferes with everything I try to do.

Just installed Jessie on a rig. Instead of messing with the /etc/network/interfaces with setting up static IP I used the gui to set it up since I felt unsure about doing it. Just out of curiosity I wanted to check what the gui did to my /etc/network/interfaces file, was surprise to see that it didn't do anything, so I'm wondering. Where did my new settings go? Can I edit them?
Not totally sure what sources /etc/network/interfaces.d/* does but the directory is empty, thought it might've gone in there.

I have two identical hard drives; same make, same manufacturer, same model, and same capacity, which I'm trying to run in a RAID1 mirroring scheme. The problem: configuration files for md arrays only lets me use device names, such as /dev/sdb and /dev/sdc. To keep these the same (and in the same order) when I boot I wanted to write a udev rule for them. Unfortunately, I have no way to differentiate between these two drives, as they seem to be identical. Normal methods of differentiating by size or model name wont work. I think I can use UUIDs; but I neither know how to get the UUID of a device/partition, nor do I know how to use it (if it is possible) in a udev rule.
Solution:
run
udevadm info --query=all --path=/sys/block/sdb # or whatever block dev
Look for and use "ID_SERIAL_SHORT" which is unique even for identically manufactured disks. Write a udev rule based on this property.

I'm running Edubuntu 10.10 64 bit on an LTSP box here at work. Two of them, in fact. In each instance, we have a Ricoh MP2500 network printer.
Scenario 1 - I print, it works. Scenario 2 - I print, the printer heats up, the wheels spin, yet it never actually prints a page. Each box is from the same Edubuntu install CD. Each box is set up as identically as possible with very minimal differences (aside from software set, as one is for Middle School and the other for High School) Each scenario has an identical printer. Each scenario has the same printer driver.
