How do I migrate a system from one machine to another. By this I mean install a new system on a new machine then have a copy of all the settings etc from the old one copied to the new one.
View 5 RepliesI've been experimenting with Debian coming up with a system with suits my needs. I have done this and I'm wondering, "Do I have to start from scratch on my physical machine or can I convert an existing VDI to IMG and possibly port it to the physical machine?"
System: Debian Testing
I was using a Sony laptop with Ubuntu 10.04 installed on the machine. I have just bought a Mac and I will be using Ubuntu 10.04 as my primary development OS by virtualizing it using VirtualBox.Now, my requirement is, I had a near perfect development environment setup on my Ubuntu box and I don't want to install the packages, apps, setting etc again on my VirtualBox VM.
I know there are ways to export apps, setting etc, but is there some app which will actually create a VDI disk for my VirtualBox which, when I plug in to my VirtualBox, I will get the old Ubuntu on my VM.
I have a working system running some older fedora, and new hardware running a fresh, new fedora install. I want to basically transfer my computer's "soul" into the new system ( user's stuff, firewall configuration, the various server & security configurations, etc.) and basically any customizations and non-hardware related packages installed that weren't part of the standard fedora install process. I'm looking for a magical easy button I can push to do all this (pause for laughter). Essentially, I want to "upgrade", but starting with a clean install on a different computer with different hardware. I have a vague idea of what needs to happen, like copying the /etc/*.conf files, /home directory, etc. but this seems very tedious, and the likelihood of me forgetting or overlooking something is 100%, and copying over entire disks or partitions wholesale is not necessary, and does not work for this scenario. I need to place/merge just the right files/directories in just the right places with surgical precision. Is there a utility for this? Maybe a way to diff the packages of the 2 computers and install the difference? Or at the very least some sort of checklist that could be scripted for my system? I'm desperately trying to avoid the pain, human misery & suffering encountered getting everything in the 1st system going.
View 3 Replies View RelatedI am currently considering migrating an openSUSE X86-64 system from 11.3 to 11.4. There seem to be 2 possibilities, upgrade or reinstall. Opinion seems to be divided on the process of upgrading from the DVD.I have not been able to find any reasonable guide to using either method to migrate an 11.3 system to 11.4 and have the 11.4 system in the same working state as the 11.3 system was. What I have found for the reinstall method is trivial. for the upgrade method I have seen a reference to running rcrpmconfigcheck but I have been unable to find a man page for it on my 11.3 system or via google.
Does such a guide exist? It should be created by the openSUSE project for each release.If it works the upgrade process looks to be the best method. The last 2 migrations were via the install method. 10 to 11 but also 32 to 64 bit and then 11.1 to 11.3 onto a new machine before moving the data across. Both rebuilds took many days.I have seen many posts saying that it is very quick to rebuild the system. As little as 2 hours has been quoted. I have not yet seen an explanation of how they do it. I suspect that they rebuild systems regularly and have it all scripted or their systems are very simple. An explanation of how it is done would be interesting.Given that I do migrations once or twice a year, building and testing a script to do the migration is probably not worth the effort especially as the only test machine is very old and slow
I have just had an auto-update, and the process has stopped with the warning above. The full error message is given below.

I have a linux machine with 2 ethernet ports(eth0 and eth1). eth0 is connected to a router which assigns it an IP address 192.168.1.2. eth1 is connected to a switch and I assigned it an IP address 192.168.1.254 using "ifconfig eth1 192.168.1.254 netmask 255.255.255.0 up". How do I ping eth0 from eth1?

- Has connection to machine C and machine D. Machine C and D don't have internet connection, but machine B can connect to those machines because machine B, C, and D are located in the same network.
I need to connect machine C and D via machine A. I heard it can be done using ssh between A and B, but I don't know the details.

View 1 Replies View RelatedI had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*
[Code]....
I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.
I try to access my ubuntu machine via my Windows Machine (Samba Server on Ubuntu Machine).

View 2 Replies View RelatedI have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

View 6 Replies View RelatedI have ubuntu-8.04.1-server installed on virtual machine. It works perfect. Now, I made copy of this virtual machine. I started that copied machine and it works fine, except one thing: network does not work!
I have several others VMs with freeBSD, openBSD or Windows on it, but only ubuntu machine hes network problem after coping. I tried some other VM with ubuntu on it - same problem! I downloaded VM with ubuntu - same problem.I take a look into /etc/network/interfaces file and it looks just as it should (same as before coping) but ifconfig command returns parameters for lo only (before coping there was eth0 and lo).
I am trying to establish the easiest way to share a folder from an Ubuntu machine to a Windows machine.In the past I have added things to smb.conf and that has all worked fine but what I am trying to do is to figure out what the "new user" way of doing this is so that when I am helping other people I know I am getting them to do the simplest thing.I completely removed samba and reinstalled it so that I didn't have any configuration. Right clicked on a folder and selected "Sharing Options" ticked the "Share this folder box" gave it a name and a comment and ticked the other two boxes.
When I went to the windows laptop then it kept asking for a username/password and nothing worked.Back on the ubuntu machine I did sudo smbpasswd -a [username] and created a blank password. Now from the windows machine I can access the shared folder.Is the smbpasswd step still required? It's very confusing for a new user as there is no suggestion that anything other than right clicking on the folder and choosing the options you want would be required. Is it something to do with the fact that this is an ubuntu machine that has gradually been upgraded through versions and this problem wouldn't have been there from a new install?
I can set-up an ssh tunnel from machine A to Machine B:-
fred@my-linux:~$ ssh -P myport fred@myserver.homelinux.com

what address and port will my tunnel 'appear' on machine B? I want to send a stream back from B to A up the encrypted tunnel, not over the open network.
I have an issue with the manner in which Network Manager is configuring the network and short of ditching Network Manager I can see no solution.The issue : Getting a machine to update its machine name in the DNS serverSounds simple doesn't it I operate a FreeBSD based firewall / DHCP / DNS server, using a default Network Manager DHCP configuration the Fedora clients do not register their names with the DNS server when they obtain an address.
I have traced the communications with Wireshark and the Fedora clients are NOT supplying the PC's hostname as part of the exchange so this is NOT a DNS server configuration issue. If I uncheck the option 'Automatically obtain DNS information from provider' under the DHCP settings the Fedora clients DO register the hostname that is put into the Hostname (optional) databox. They do NOT however store the DNS server IP address or any other records defined by the DNS server.
Is there some hidden settings or is this a bug because it isn't acceptable 'DHCP' behaviour if it isn't possible to automatically set DNS server IP addresses and at the same time register the hostname during the DHCP negotiation. Before it is said I know I can use a fixed DNS IP address but am not prepared to long term, I am also not prepared to define the Fedora clients with a 'static' IP. I am similarly not interested in playing around with scripts or any other such 'frigs' to achieve what should be a standard activity - registering a host with DNS during the DHCP negotiation.
I need to access a Windows Server 2000 machine using a Linux machine via KDE, but that will migrate to Gnome. The Linux user to connect to Windows machine, you should open an application 'XYZ' automatically, and only this, denying any unauthorized access. When you close the application 'XYZ' communications (RDP?) Should be terminated. Do I need a log of accesses and possible attempts to circumvent the system and access other application.

View 6 Replies View RelatedI have a ubuntu 9.04 machine i'm using as a file server. I'm able to see that machine from any XP machine, connect to it's shares play music, movies, work off of it NO problems. But i can't view the shares from a windows 7 home edition PC (garbage). AND, from the ubuntu PC, i can't see any of the other shares on network. I get "Fail to receive share list from server".
NOTE: Originally i had this machine connected with wireless card because of location. and I was able to see all shares then - both ways (still not from Windows 7 PCs though). However, when I moved to hard wire connection, the network disappeared. I've tried changing IP addresses, changing switches, but no network. I'd like to keep it hard wire. Can anyone point me in right direction or am i missing information?
I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
2. /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4
search locadomain
4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
[code]....
I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.
I've run into a weird problem. Two of my linux machines (A and B, both running CentOS 5.5) are connected to the same wall ethernet socket via a hub. Bothf them are configured for static IPs. The trouble is that when machine B goes offline or hits a kernel panic, machine 1 goes offline too. What I've noticed is that in this condition the "route" output from machine A does not show any entry for the default gateway either The contents of /etc/sysconfig/network-scripts/ifcfg-eth0 for machine A are:
Code:

View 7 Replies View RelatedA drive on my Linux machine is NTFS as the file system. There's a file corruption issue of some kind for copying files from the drive to another or another PC result in I/O errors. Overall, I work with 2 systems, one Windoze, the other Linux. I'm about to switch the roles of the 2 machines. The one with the corrupted ntfs partition is about to become my Windows machine and the Windows machine is going to become Linux.
Since I will be installing Windows on the machine with the problematic ntfs partition, I'm figuring at some point, Windoze chdsk will kick in and fix the drive. (Windows will be installed to another drive that is perfect right now.)
Is this a correct assumption? Or, do I do everything I possibly can to fix the corrupt partition prior to the new Windows install? If this is true, what are my options for fixing corrupted files under Ubuntu? Research I've done hasn't yielded much in results and a definitive answer for fixing corrupt files in Linux.
