if I need to install Linux o/s in 50 or 100 machines, how do I do it ? (lets imagine that all the machines are identical)
Is it possible to install in one of the machines and just clone in all of the other machines (without actual installation). If so , how do i do it ??
I have tried to boot from Fedora 10 CD on Compaq Evo D510 desktop as well as HP Pavilion DV6700 Laptop several times. Goes through everything for a long time. Ends up in a screen with colored stripes on the desktop and a blank dark screen on the laptop. I do see the wireless light on the laptop turn blue from orange indicating it is enabled. But was of no use. Both machines crash at the end. I tried both GNOME and KDE.....both crashI am suspecting the display drivers. The desktop has a Intel Chipset and the laptop Nvidia GForce 8600 I guess....These are not old comps. The desktop is just a couple of years old and the laptop is brand new. This is without actually installing Fedora

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.
So I'm a newb to ubuntu and I have two desktops I just had wiped clean, there is nothing on the drives. I DL the latest version, burned to CD and tried to get the machines to boot the CD so I can install the software.
I get nothing but reboot retry press F1.
I have now got three machines with Debian on in my home. I use Mobile Broadband with a very modest monthly limit and remember somehow using Synaptic to gather either Updates or packages to download on one machine where there was another type of internet and could then move the packages back to my computer. Can anyone here remind me of what I would have done there or suggest a means of getting these three updated without blowing my limit. I'd either use a relative's broadband and my netbook, or do the Updates once at home and move the packages to the other two machines.
I'm using Debian 6.01, Gnome edition, 64 bit, on an Atom N450 netbook, a 3ghz dual core AMD pc and a a 2 ghz single core AMD pc, whatever of this is relevant. They have slightly different programs installed but are at the same stage of not being updated yet, with 252mb of them to add.
I just inherited a lab full of computers currently running XP and 9.10. They all worked when I last saw them. Recently, tech support re-imaged the XP partition and now I can't boot into Ubuntu. Obviously it overwrote the bootloader that was there, but I can't get it back. The general setup is XP on /dev/sda1 and Ubuntu on /dev/sdb1 with swap on /dev/sdb5.
I've followed a bunch of instructions about reinstalling grub by chrooting into /dev/sdb1 (right? that's the one I should use), grub-install and update-grub all run without a hitch detect both Ubuntu kernels, memtest and the XP install as they were before the reimage. Exit and reboot, it still boots straight to Windows. If I move the boot flag from sda1 to sdb1, the computer hisses at me about not finding anything to boot.
I've gone nuclear on one computer and installed 10.04 on sdb1, but it still boots to Windows. I feel like I need to do something to the MBR on the Windows drive but last time I did anything there I had to fix it with ms-sys. I left out anything wicked important, I'll get what info you need. Oh and if upgrading to 10.04 in a trick fashion will help me, by all means suggest it, because once they get going I'm upgrading anyway.
I do some volunteer work repairing and re-purposing older computers for the Salvation Army Thrift store where I live. Of course most of the computers we get are older. My reason is to get some of the poorer kids a fighting chance at school. We sell these things for next to nothing to accomplish this. I include free tech/training support for 30 days to get them started as. My problem is that finding a version of ubuntu and openoffice that will run on them is becoming difficult. Any suggestions as to a version that works for those not real familiar with computers?
View 7 Replies View RelatedI'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 1 Replies View RelatedI have a home network with 6+ x86_64 machines, all with similar setups. In the past (FC10 and before), I've had common package repositories (e.g /var/cache/yum/fedora/packages) shared via NFS with all the machines (and with keepcache=1 in /etc/yum.conf). That way, a given RPM only got downloaded once; the other machines would then pull it from my local package repository. And I don't mind the disk usage of keeping one copy of all my old RPMS around.
It seems that while DRPMS is great for a single machine, it doesn't make sense in my case. If I have to download the DRPM 6 times (and take the time/CPU hit to recreate the RPM 6 times), I might as well have downloaded the RPM once and been done with it. Is there a not-too-convoluted method to keep a common package repository across multiple machines even with DRPMS? Or, better, to have that first downloading machine pull a DRPM, generate the RPM, then save the RPM in the local shared repository?
i have a cheap-arse employer who doesn't provide any data backup for us. so i've setup my own very simple server with ubuntu 10.04 (no raid). from my linux desktop i want to backup to my file server. from my file server i configured samba to allow me to access my data from the many Windows PCs in the place. I also have a USB drive for when i go home or to another building.
most of my work happens on my linux desktop. so i use rsync to 'backup' from there to the file server. can i use rsync to keep my usb drive also sync'ed? in the same command?
when i access files on my file server from a Windows PC via samba, and change something, will rsync pick up that change on the server, and migrate the changes back to my linux desktop?

we are having new printers. At the moment we over 1000 machines on multiple sites but no print server they are manually added on the machine ( I know don't ask).
Anyway there is no way they would let use a windows server so the only option I have is to use linux however I little unsure if it is capable of doing the job I need it to do. Basically I want to add the printers on the linux server either using samba or ipp (I would assume samba would be best).
The reason i want to do this is when we have to do around the machines I just want to go around the machines and just the map the printer and it brings down the driver and config etc as we want them to duplex. The issue is I been trying to gain information on the internet and getting conflicting information apparently I can add the windows driver onto the server so when I map the printer it brings it down. However some guides state you still have through the whole process of adding the printer and then choosing the driver etc. Which kinda of makes it pointless to do the printer server since I would already have to do this anyway if we don't have one.
I just want to go be able to go around the machines and for example click star run and do something like \192.168.1.1printer01 and then it done kind of thing.
I have three Ubuntu desktops that I would like to upgrade from 9.10 to 10.04. Is there a way to avoid having each PC download the same packages? Is there some magic I can do with two of the PCs to maybe point the software source list at the third 'master' PC that does all the downloading?
View 2 Replies View RelatedI've been having some problems trying to get a new netbook working with China Telecom's 3G service (works wonderfully in Windows, but still trying to figure Ubuntu out), so until I figure out the problem with this Huawei modem, I've written a quick python script to handle updates/installations on the Ubuntu side. (Synaptic does fine on generating download scripts for packages, but it needs an option to handle updates as well)
If anyone else has a use for this, you're welcome to use it. Please let me know what needs to be changed to make it work on your box.
I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program.I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"?
For example:
Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?
I have the following network setup.
* A static IP from my ISP
* A router/modem in my home
* Two machines: MachineA and MachineB connected to the router
Currently, the router is setup so that ports 80, 21, and 22 all forward to ports 80, 21, and 22 on Machine A.
However, I would like to be able to SSH into Machine B as well. What is the best way to accomplish this? I figured I would setup Machine B's SSH server to listed on a random port like 2995. So then I would configure my router so that incoming requests from port 2995 are forwarded to port 2995 on Machine B.
I'd like to know if it's possible to set the DISPLAY environment variable in order to display on two machines, the local and the remote, at the same time.

I have looked at a few Linux based OS's. I did notice that when you install fedora live desktop it gives you the option to connect to one of the above. So I am looking for a complete solution.

2. Add fedora/linux mint machines to server to use new security settings. (or other linux build)
I used unetbootin to make a bootable USB key (a BT4 persistant live cd)
But it wors only on a few machines. (only 1 out of 6 i tried) Most of the time boot sequence get stuck on a blinking prompt cursor.
Ex:
Attempting Boot From Floppy Drive (A:)
Attempting Boot From USB Device
_ <-- stuck...
Then boot on HDD
Is it do to the usb key or machines that do not load mbr the same way?
Edit: the stick is formated with MBR have 2 partitions. The first is FAT32 and active, second is ext3
PCs i have tested can boot on USB (at leat you can select a USB device for Boot)
Is it possible to copy a file on multiple remote machines through scp in one command?

View 2 Replies View RelatedI usually monitor machines in the network via ruptime. But one machine (lambda) acts very odd. It never shows up in the output of ruptime, unless ruptime is run from a particular client (delta). For example, say I am logged in lambda. This is what the output of ruptime and few other commands are:
[Code]...
Linux delta.grp.vpncc.org 2.6.18-53.1.21.el5 #1 SMP Tue May 20 09:35:07 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux Only difference between delta and other machines is the fact that delta is the file server that hosts the nfs directories shared in all the machines. All the machines are in the same subnet. All of them run either RHEL4, RHEL5 or CentOS5. lambda runs RHEL 5.4, delta runs CentOS 5.2. I tried restrting rwhod daemon on lambda, but no change. why lambda is playing this hide and seek with ruptime?
I just narrowly passed another exam on UNIX Academy. Their DVDs are incredible. While I made some mistakes here and there.I was really stumbled upon a question that was formulated something like "SNMP for managing Linux machines remotely".I can't remember the exact definition. I'm not sure what it was about.I was under impression that SNMP it is a carrier protocol for commands like "ping" and "traceroute". I was trying to read about it online but it is way too broad and technical, they're loosing me on very first page. I suspect there's some kind of product or technology that uses SNMP in some way to handle Linux, I'm not sure.

I have a network of 20 machines, all running Ubuntu 10.04.
Each machine has about 200[GB] of data that I'd like to share with all other 19 machines for READ ONLY PURPOSES. The reading should be done at the FASTEST POSSIBLE WAY.
A friend told me to look into setting up HTTP / FTP. Is it indeed the optimal way to share data between the machines (better than NFS)? if so, how do I go about it?
UPDATE: Just to clarify, all I want is to be able (from within machine X) to access one of machine Ys files and LOAD IT INTO MEMORY. all of the files are of uniform size (500 [KB]). Which method is fastest (SAMBA / NFS / HTTP / FTP)?
