Ubuntu Installation :: Multiple OS's On A Disk With LVM Setup?

Mar 27, 2010

I want to be able to install multiple operating systems on a disk setup with LVM. I am uncertain as to how to go about this.I read somewhere that you can do it, but that only one /boot partition should used for all systems(they are all linux).get going on this? Do I boot from an installation disk and follow that path some how...or is there some other method I should be following? And how do I use one boot partition for all OS's? I had a problem with this once before..so need to ask, especially with the LVM thrown in the mix.

Ubuntu Installation :: Multiple Installs Of 10.10 With The Same Partition Setup?

Feb 4, 2011

I work at a local library. In a few days I am getting 8 new HP g72t laptops. Is there a way to do multiple installs of 10.10 with the same partition setup, installed programs, config settings , etc? I am a volunteer and have set up many ubuntu installs before but always had each machine old and different. Now I would like to automate all the installs somehow.I picked that laptop as linuxcity.com sells them with Ubuntu installed.I got them with windows and plan to remove win 7 and do Ubuntu 10.10

Ubuntu Installation :: X11 Crash Using Fglrx When Setup Multiple Screens?

Apr 29, 2011

After the installation I have 3 screens setup, on DVI, HDMI (to DVI) and DisplayPort this is using and AMD HD5570 video card. With this configuration mirrored everything is fine and I can see all three displays.However having 3 copies of the same display is worthless, so I want a separate desktop per display.This is when everything goes wrong, after making the change to have 3 displays it fails to work, ie it crashes with the message below (full log is attached as well)Now I can use any 2 monitors independently with the third one mirrored, but I can not have 3 independent monitors configured on the card without X crashing. The exact same config, did work fine in Windows (where I verified the setup).

Backtrace:
[ 352.624] 0: /usr/bin/X (xorg_backtrace+0x26) [0x4a2626]
[ 352.624] 1: /usr/bin/X (0x400000+0x6219a) [0x46219a]

Ubuntu Installation :: Have Multiple Distros On One Hard Disk

Sep 12, 2010

I know it's possible to to have multiple distros on one hard disk, and set it up so you can just have one /home partition and use it for all of the distros on that system. My question is, how efficient is that? Does it bloat the /home out with a whole bunch of stuff that might slow a particular distro down because it's filled with stuff from another? (I.e configs). And let's say I have two distros that are of different bases, say ubuntu and arch, does this make a difference? I know obviously that my personal files will all be accessible and not matter which distro they are being read from, but I'm talking more about the hidden stuff.

Ubuntu Installation :: No HD Recognized To Partition In Disk Setup

Apr 23, 2011

When trying to install Kubuntu 10.04 32-bit (or Ubuntu 10.04 64-bit) it does not show me any hard drive to partition in the 'Disk Setup' (I've clicked all the buttons on that screen to see if I can encourage it!) and will not let me past that point in the installation process (because, obviously, no root file system has been defined). I have done something very bad to my computer. As an aid to selling my computer, I decided to (try to) install Windows 7. I booted into a live Ubuntu CD and used Gparted to reformat my hard drive. After several issues with the Windows boot CD I decided to pull up FastBuild Utility, and did something which included deleting LD and Defining LD again. Didn't make any difference with the Win 7 install. I am now trying to return my computer to a functional state in the sanctuary of Kubuntu 10.04.

Tried installing Win XP which I have installed successfully on another computer. Got an error message: "Setup did not find any hard disk drives installed in your computer" - presumed that was because of something I did with FastBuild Utility (2006). I've tried as many different options in this as I think could make a difference. Booted into DR-DOS and deleted partitions and created a FAT 32 partition. Booting into the live Ubuntu 10.04 CD again and used GParted to create an NTFS Primary Partition taking up all the hard drive. As above and deleting all partitions in GParted. Checking into BIOS and changing the SATA Operation from 'RAID On' to 'RAID Autodetect / ATA' (Now changed back again to the default 'RAID On.').

Loaded Defaults in BIOS - I've been running Ubuntu 10.04 x64 on it since it came out with these settings. At all points I have tried to install Ubuntu 10.04 64 bit, Kubuntu 10.04 32 bit (and Win XP) with no success. In the Kubuntu install, when I get to the Disk Setup part of the installation process it offers me no information whatsoever. My hard drive has all partitions deleted because of my last action in GParted. May need to define a partition. What as? I'm still convinced that my playing in FastBuild Utility (2006) is probably the root cause of this, and so quite likely to be a good place to go to solve this. I think I've set everything as it was, but can't be 100% on that.

My Computer:
Dell Inspiron 1721, AMD Turion x64 dual core, FUJITSU MHW2120BH 120GB HDD.

OpenSUSE Network :: 11.2 Xen Bridged Networking - Setup Multiple DomU Through The Default Bridge Setup

Feb 4, 2010

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

Ubuntu :: How To Get Multiple Screens Setup

Jun 3, 2010

I was wondering when and/or how to get multiple screens setup and working in unison. Currently I have 3d rendering working but all of my screens work as separate desktops. They all have their own start menu and panel bar. I cannot move a window from screen to screen. I have to open a new window in that screen and then it is stuck on that screen and can not be move any where else. When is this going to be fixed because until it is unfortunately Micro Slop will still have my business. I am a power user and enjoy my 4 screens when they work in unison, not as individuals.

Ubuntu :: Dual Head Setup - Multiple Conky

Jun 14, 2010

I am trying out conky for the first time and rather enjoying it. I have a small frustration though. I have a dual head setup and would like to have identical conky's showing on both monitors. I have tried creating two .conkyrc's (.conkyrc1 & .conkyrc2) and then using:-

Code:
$ conky -c config1
$ conky -c config2
to launch them, this results in only one of the two conky's displaying. I did at first think that maybe they were on top of eachother, but one conkyrc is set bottom_left, the other bottom_right so they should not be right??

When I try to run them as above terminal shows:-
Code:
gregg@burt:~$ conky -c config1
Conky: invalid configuration file 'config1'
Conky: invalid num arg for top. Must be between 1 and 10.
Conky: invalid num arg for top. Must be between 1 and 10.
Conky: invalid num arg for top. Must be between 1 and 10.

Fedora :: 15: Setup Gdm (multiple Screen)

Jul 24, 2011

I am just trying out Fedora for the first time (coming from Gentoo and later Ubuntu).

So far everything works fine, but I have one problem with the gnome display manager (gdm), which is responsible for the initial graphical login screen.

My graphics adapter (nvidia) has two dvi-outputs, and i use them both. One is my primary display, the other one is used for my projector (watching films etc).

When starting Fedora, unluckily, the gdm login screen is shown on the wrong output (the projector, which is only occasionally turned on). I'd like it to be shown on the primary display.

Now I learned that gdmsetup disappeared in this release of Fedora. How can I achieve this goal now? What I found out through research is that there is a config-file (/etc/gdm/custom.conf), which can be used to configure gdm. But I don't have a clue how to. I found the following official documentation: [URL].

Ubuntu :: Netbook Boots Into Setup Multiple Times Before Boot Or Freezes

Jun 4, 2011

I actually have it installed on two of my computers. One is an older Acer Aspire 3100 that dual-boots windows 7 and Ubuntu 11.04, and an Acer Aspire ONE that has Ubuntu 11.04 as main OS. Before Ubuntu, (even currently) I'm a MAC user, and i'm really liking Ubuntu. On my 3100 it works just fine except the screen flicker on wake, but a quick reboot will solve that.

On my Aspire ONE i've had to re-install ubuntu multiple times. (we're talking 5 or 6 in the last month) Sometimes, it'll boot up to absolutely nothing. One time I got a weird error message everytime it booted. The last install froze up a lot, and eventually would only start to boot into setup. I reinstalled Ubuntu, again and it worked until I shut it off. Boot back up, same thing. Threw me right into setup. I was able to get around it after 5 or so tries of rebooting, hitting ALT F11 and somehow got into ubuntu recovery, but loaded normally. I'm using it now and it's working great currently.

Specs on the ONE

1.5GB Ram
8GB SSD (could this be the culprit?)
ATOM (1.8 or 1.6) GHz Processor.

Halfway through this fiasco, I put windows XP on it and used it solid for 3 days without any of the mentioned above issues.

CentOS 5 Networking :: Multiple NIC - How To Setup VMware Servers

Apr 15, 2009

So I have a pretty big networking nightmare on my hands right now. Stepped into the dog crap with this one, told my employer that I knew how to setup vmware servers right? Its not hard, install CentOS, install vmware, run the config tool, bridge the network, down the road we all go right? We have 3 servers running about 10 virtual servers.

Here is what we have all together.
CFU <- This is the internet. We have IP ranges xx.18.230 - xx.18.241 Gateway is xx.18.254 and subnet is xx.255.128
DELL PowerConnect 3348 Switch <- This is what everything is pretty much jammed into.
VMH1 <- This machine has 2 NICs
eth0 connects to the DELL switch somewhere on the upper 30+ ports
eth1 connects to the DELL switch on port 1.

It uses firestarter and is the gateway for our internal internet on 192.168.11.XX using IP 11.254. It has 4 vm's on it. One of them is the domain controller, hooked to eth1 using IP xx.11.1. The other one is a server for managing remote backups, it has an external IP linked to eth0 of xx.18.234. The other 2 vm's are for misc remote login stations that use internal ip addresses linked to eth1. It hasn't had a single problem communicating on either one of the ports..

VMH2 <- This server hosts a web server, and some other misc stations.
It hosts a web server on xx.18.230 and xx.18.231
It also hosts 2 workstations on a seperate network, through another router that is wireless....

Now, we have the problem child, VMH3
VMH3 <- This hosts...nothing. It sits and has a ton of storage, but does absolutely nothing, but won't communicate out either one of its network ports.
The xx.36.xx and xx.22.xx networks are there because we have multiple businesses in the building that shouldn't see each other.

Ubuntu Servers :: Setup An Outbound SMTP Mail Server With & Using Multiple IP Addresses

Mar 15, 2010

This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.

It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.

I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):

All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.

My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.

I have configured Postfix for Multiple IP Addresses.

I can, from the command line, send successful test e-mails and receive them in my personal account.

As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.

Here are a couple of my questions:

Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?

How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?

What can I use to check and ensure that this server is in fact sending out emails on all 5 IP

Addresses (I heard that there is a program named "Postal" that may help in determing this).

Debian Configuration :: Multiple Virtual Servers Be Setup In 2 Desktops?

Jun 12, 2010

I now have 2 desktops running debian. I have virtual servers running in desktop 1, and I am hosting my photos using Gallery2. I have copied Gallery2 and the mysql over to desktop 2. I have entered port forward to desktop 1 using port 80 (using my router), and desktop 2 using port 1000. I can only access Gallery2 in desktop1. If I tried to access Gallery2 in desktop 2, I got re-directed to desktop1.

Questions:

1. Are home routers capable of port forward to more than one computers in a home network behind the firewall of the router? It is Belkin N+ router.

2. Can multiple virtual servers be setup in 2 desktops?

Debian Configuration :: Setup Multiple Mac Address Over Single Ethernet Interface?

Jul 23, 2015

I want to configure multiple virtual ethernet interfaces over a single physical ethernet interface (eth0) and for each virtual interface the MAC address must be unique and the IP address must be Static.Finally all the virtual interfaces must be able to communicate both internally and externally and the traffic should be captured using wireshark.

I need to have such kind of setup to communicate devices individually using one physical ethernet device.

Because I was fiddling with few kernel modules like MACVLAN and MACVTAP and successfully enabled those modules and rebuild kernel. Using macvlan and macvtap I can configure virtual interfaces with unique mac address and static IPs but while capturing packets using wireshark interfaces behave weirdly.

For example say on HOST machine I have 1 physical interface and created 3 virtual interfaces as shown below.

Interfaces :

eth0 (physical ethernet interface)
IP: 192.168.A.A
MAC: aa:aa:aa:aa:aa:aa

[Code] ....

First from above interfaces I started pinging eth0 internally from host machine in which it worked as usually.

Second I did same externally from other machine which is connected to the same network of Host machine, and this did work as usually.

Third I pinged first virtual interface veth0 both internally and externally and this also works and after that I did check source and destination MAC address using wireshark tool-where both showed up there respective MAC address.

Now triggers the issue, where I pinged second virtual interface same like I did for first one, but this time ping was success and where as in wireshark tool the MAC address for veth0 is picked by veth1. This is where I got stuck and this issue happened for all the remaining virtual interfaces.

I couldn't see any virtual interface showing their respective MAC address, as of the remaining except the first virtual interface has been picking the first veth0 mac address.

Software :: Multiple Disk Images From Single Read-only Image

Jun 16, 2011

Oooookay, so basically the idea I have is that I would like to boot Windows XP over an AoE connection. This is no issue, however the problem comes when I want to have a single, read-only image as the base image and want to be able to boot multiple computers off this image.Licensing issues aside (let's assume that this complies with all licensing issues, or we can think of it as just a conceptual "how could we do this"), the basic issues are thus:Each boot of Windows will require a writable AoE device...The original disk image must be read-only to avoid changes in 1 boot affecting all boots(As far as I know) The AoE device must be a disk image, or some block device rather than a mounted file system (if this is not so, aufs could be used)So the long and the short of this, from what I can tell is that we need a read only device that we can write to.

At the end of a session, the changes to the device will be discarded, so these can be thought of as simple temporary sessions. This means that there is little concern with having changes to the original read-only image effecting the modifications to the "duplicate" images.

I would like to avoid duplicating the image for each instance, however if no solution can be reached then this could be a possibility (every boot, we can copy the image, give the fresh image to the new boot and remove when done)Optimally, changes to the filesystem will be written to a different filesystem (much like what aufs does, however as stated earlier, afaik aufs only deals with 2 mounted file systems, whereas we need the end result to be an image or block device)Sorry if I havn't explained this particularly well, however I've been trying to think of solutions, caveats and generally how to define the problem as I was writing. If you think that this idea is ridiculous because software x handles the problem better, I'd be very pleased to hear about it, but the basic requirement of temporary, network bootable windows xp sessions still applies.

Networking :: Setup Multiple FTP Servers With Distinct Data Sets With 1 Master FTP Server?

Aug 27, 2009

Faced with disk-bound issues on a FTP server with high traffic. Would like to set up multiple FTP server nodes with dedicated storage for each node where all FTP access is managed by a master FTP server. So, a user would FTP to a single externally visible IP address for the master FTP server and then get routed to the appropriate FTP node. Are the mutiple FTP nodes required or is there a better way of doing this? Perhaps only one FTP server is required and then each node would serve as a separate file server
