View 8 RepliesI have a project in school that the requirement is to show the proof of concept of a high availability virtual servers. the guest operating system for the test case will be a Windows variant and a Linux variant that if the main host that hosts both of this VMs fails, both VMs will be restarted on the backup host. Simple enough with VMware vSphere and citrix xenserver with essentials with their enterprise features, But I am not allowed to use a software that one will need to pay-for or is only a trial version, i need to use an open source solutions, and i am not allowed to use virtualbox.
the school has provided me 2 server class 64bit hardware with intel-vt support, i have my laptop for management tools and to also run a virtual appliance for a iscsi target (openfiler as a vm in virtualbox in my laptop).
I have figured that i will use KVM on a ubuntu server as my hypervisor but i cant find any how-to on how to implement a high availability setup that will run a windows variant as a guest. can some one give me a step by step on how to do this.
from my research it looks like i will need DRBD and heartbeat, but i dont know how to use them and if they are applicable in my needs. I wouldn't probably use DRBD since I have a sudo SAN with my iscsi target, so i can probably use open-iscsi.
I intend to set up a web site on a dedicated web server in colocation (containing nothing else except the server OS).Is it sufficient to make all files read only and use Apache mod_security or can a firewall offer extra necessary protection?

Today I get the following error on the viewer software: "Server did not offer supported security type" The only thing that has changed was that I installed a bunch of updates yesterday afternoon, but I am not sure what changed.

I've set the VirtualBox configuration to use a Bridged network connection so that I can access the internet through the Ubuntu guest and to access the Ubuntu apache server through my Windows host.This is all running on my laptop which connects to various routers using dhcp (some ip addresses start with 198. while others start with 10.) What I need is a single static ip address (or hostname/url) to setup my cms (drupal).how I can accomplish this given the varying routers the laptop connects to?

So the virtual terminal is there and listening to the keyboard and running, just not creating a display.
This machine has been working fine with 08.10 for quite time up until yesterday, so I don't believe it is a hardware problem.Any ideas why the video on the virtual terminals would not work?
I have a virtual private server that I am trying to connect to using x11vnc. I ran this through ssh to setup gnome
sudo apt-get install gnome-core
sudo apt-get install gdm
sudo /etc/init.d/gdm start
sudo dpkg-reconfigure xserver-xorg
I later ran sudo apt-get install ubuntu-desktop to see if that would help.
Code:
#cat /etc/issue
Ubuntu 10.04.1 LTS

Code:
#sudo startx
Fatal server error:
xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory)
I assume this is because it probably doesn't have a video card.

I'm not sure is this is possible or not, but what I would like to do is take my public address mydomain.com and configure a virtual host something.mydomain.com only instead of having the content on the same server I would like it to point to the IP of my virtual machine that is in my private network and display that page publicly. Does anyone know if this is possible, or how to do it? I have done this with port forwards, but would like them both to be on the same port.
View 3 Replies View RelatedI am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

I'm a web developer and I am building a site on a CMS that has issues moving from a WAMP server to LAMP. The live server is LAMP and I am running Windows 7. I don't want to run into problems moving from the test server to the live server, so I was wondering if I could somehow run Linux using a virtual machine (using Windows Virtual PC which I think supports Linux or VirtualBox) and then using a Linux equivalent of WAMP2 server as a test server. how to do this and what the best Linux distribution to use would be?
View 2 Replies View RelatedI have an Ubuntu Desktop 11.04 virtual machine using VirtualBox on my Windows 7 system.
Up until now I have been doing all my development within the Ubuntu environment but unfortunately, I don't like it. I want to move back to Windows, which is much more familiar to me but I would still like to access the virtual box like a virtual server as it is already set up with Apache, PHP, Pear, Git etc...
How can I make the two work in harmony? I essentially want to be able to start the VM and connect to it as if it was a server machine somewhere on my network, without having to actually buy another machine to put on my network.
I'm working on a side project where I would like to install three ubuntu server systems,each with only one task.So server0 would be the apache server, server1 would be the database and server2 would be the file server.which key terms I should be researching?
View 9 Replies View RelatedWill there be any issues installing and then subsequently running a Microsoft Windows Server 2008 R2 installation on a VirtualBox VM on a Linux host (Ubuntu 11.04 64-bit)? I require Windows Server 2008 R2 for a course I'm taking, and I dont have any systems to install/deploy it onto.

I have a home server that I have been running for some years and am constantly tweaking / playing with it resulting in numerous reinstalls (and upsetting the wife!). It does nothing critical but I use it mainly for:
backing up my laptop files
XBMC
ZoneMinder
Due to the number of times that I manage to break it, I have now thought about setting it up as a base system but with virtual machines looking after the seperate 'components'. The machine is an AMD Athlon 64 X2 4200+ with 2Gb RAM. First of all do you think it is powerful enough to run XBMC and ZM in seperate virtual machines? - I appreciate the more RAM the better but at the moment I am sticking to 2Gb.
I was also wondering what sort of issues may arise for the audio and video areas I will be using. XBMC currently outputs through an HDMI cable to the TV and ZM recieves video signals through a seperate video card. ( I have had my concerns in the past that there have been conflicts in the way I have set things up!). I have read a number of guides about setting a system up with virtual machines but not really found any articles about the practicalities of using such a set up at home. before I commit and spend a week pulling my hair out trying to get it all to work!
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?

We have around 50-60 people who need access to a local server primarily for secure general file storage. These employees are geographically dispersed. We currently use some(?) version of Windows Server which is maintained and updated by a IT company we keep on retainer. After doing some very basic research on Ubuntu Server, I would like to try and incorporate a pilot program utilizing the Ubuntu Server software.I was successful in installing Ubuntu Server on an unused PC that I put a clean hard drive in. I have been following the direction of the Official Ubuntu Server manual to assist in the server setup, and this has progressed my cause up to a point.
Can I run an Ubuntu Server alongside our current Windows server without bring everything to a screeching halt? Additionally, I am the only mac computer in an office filled with varying version of windows. I have begun to configure samba but need some direction from the community as to updating the workgroup so my mac can connect to the Ubuntu Server. What do I need to put in the workgroup part of the /etc/samba/smb.conf directory?I have no doubt there will be face palms by the community after reading this thread, but I am trying my best to teach myself the Ubuntu way.
I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.

I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.
First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)
Code:
Second virtual host file

And my hosts file
Code:
# The following lines are desirable for IPv6 capable hosts
Also I'm using a dyndns.org...would that make a difference?
Is there anyway for one Virtual Server to access the main host, or another Virtual Server? Or would they be totally 100% independent?

What I want: multiple virtual hosts with ssl and only 1 ip address: In my example: server = 192.168.227.129
[Code]....
In the past I found some great help on this forum, so here goes. Bare with me because it's a long story. I'll try to be as complete as possible. I've installed and configured OpenLdap on a virtual machine with ip 192.168.39.134. I've added 2 users via LAM. In the ou WikiUsers and the domain is wiki.local.
I've then created another host with ip 192.168.39.133 with mediawiki installed on it. Then I added the extension LDAPAuthenthication. In the LdapAuthentication file I added this code (only the last paragraph is mine, I added the others to show it's location in the script):
Quote:
$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );
[code]...
I know I'm close because I can't register any new users or accounts on the mediawiki site. Although I could before I added the LDAP service. This is indeed all just to test and get to know how LDAP works. That's why it's all virtual in VMWare. I did not really configure anything on the LDAP, i just installed it and chose a domain (wiki.local).
