Server :: Process Of Setting Up A Couple Of Virtual Servers In A Cloud Environment?

Mar 17, 2011

I 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!

Ubuntu Servers :: Access Virtual Instances Running On The Cloud From Remote Desktop?

Aug 8, 2010

I am a novice in the world of cloud and recently managed to configure Ubuntu 9.04 Cloud (using kvm, eucalyptus and other packages) successfully at my college for my project work. The problem is that i can only manage to view the running instance using rdesktop from any remote machine. Is there any way to do this other than rdesktop/logs? Secondly, I want to develop a application on the lines of google docs as a part of my project. Is it possible to install apache server on this virtual instance, and host a website? How will the client access this website? Which frameworks would be required or do I have to develop one?

Networking :: Setting Up A Cloud Server?

Apr 14, 2011

To be short and to the point, I want to setup a service with my clients and allow them to back up to one of my servers. What I would like to do is allow client connections via WinScp to a ssh server that has home directories for each user to backup data. If users want their data I would like them to be able to connect to my apache web server (same as ssh) and download from anywhere.

Is there a way for apache to link web directories on the server to the actual /home/user account and use the same login information/authentication?? Does this make sense? I really appreciate the help. I am not a developer or else I would simply develop a user friendly front end for to an ssh server. Since that is the case I think this is the best solution for me, as well as the easiest for the client.

Ubuntu Servers :: 10.04 Desktop Vs Cloud Server Edition

Jul 15, 2010

What's the difference in terms of scalability? We would be hosting videos and FOSS collaboration tools (wiki, forums, etc.) on 4 separate servers. If I install the cloud server, I will need to install the GUI anyways. The servers are all brand new

- 2x Intel Xeon quad cores 2.4 GHz
- 12 GB DDR3 RAM
- 4 Ethernet ports

What benefits would cloud server provide over desktop and vice versa?

Ubuntu :: Setting Environment Variables In Server 10.04

Jul 4, 2011

I always have to google about setting environment path variables when I install new software. My basic problem is that I dont know whether these variables need to be set globally or not. I have read a number of mails/tutorials which say that Environment variables should be set by simply doing an export ..eg EDITOR=nano export EDITOR

additionally I have read that it should be written into /etc/bash.bashrc

But are these really global variables or local? I want the variables to be set
even after I have logged out.

so I could also write the variable here...

/etc/environment

or here

/etc/profile

Ubuntu Servers :: Setting Up A Virtual Host In Apache ?

Feb 22, 2011

I am trying to set up an Apache2 virtual host to test sites I make from my own computer.

I used this guide to set up my LAMP and vHost, The LAMP stack seems to be working great, but I run into some problems when I try to set up a vHost

As described in the guide I

1. made a new directory in my home folder /home/[myname]/www/test.dev to put my site in (it currently contains a simple index.html file as a test).

2. In /etc/apache2/sites-available I copied the file "default" and renamed it "test.dev"

3. I edited the content of "test.dev" to look like this:

Code:

4. I enabled the site using the command "sudo a2ensite test.dev". I then restarted apache "sudo /etc/init.d/apache2 reload".

5. I edited the hosts file: "sudo gedit /etc/hosts" to look like this:

Code:

6. I restarted apache "sudo /etc/init.d/apache2 reload".

Now if I enter "http://test.dev" in my firefox's adress bar I just get the apache2 "It works!" site. What is going wrong to cause firefox to show the "It works!" page rather then my own test site?

OpenSUSE Network :: Setting Up Minimual (lightweight) Virtual Server Under Virtualbox

May 23, 2011

The only things i need out of it are: mars_nwe (Netware server under Linux) and a reverse telnet server (the dos machine is a bbs) I need the virtual server to support a very old dos machine, and while i COULD use samba for drive mapping, the VNC server I'm useing on the dos machine is a progrm called TINY which pretty much means i'm stuck useing the novell dos network stack.

how best to configure opensuse for this? I'm running the install off of the live-dvd which has quite a bit selected by default. I'm not in need of an x-server or a desktop manager, as this will be a set it up and forget about it once it works VM

Networking :: IP And Port Forwarding From Cloud To Cloud?

Oct 24, 2010

So best if you take a quick look at this image, which describes a network topology: [URL]

I am behind a firewall in the university dorm and many ports are banned. Well pretty much everything besides 80, 8080, 110, 21, 22 and the most basic ones. So I'd like to get around that.

I have a home server that is connected and reachable on the internet. So if you type in 90.90.90.90:80 into a browser it's reachable.

The task would be to set up a port forwarding or how you call it in a way that if I access my home server from the dorm or anywhere, it would act as a forwarder and forward that packet or connection to the 80.80.80.80 server on a specific port, say 2083 so that I can even access my hosting Co's admin user interface.

To sum it up: I'd like to access the 80.80.80.80 server from the dorm on port 2083 which is blocked by a firewall, but I have a home server that is reachable on non blocked ports. The home server has no ports blocked.

Ubuntu Servers :: What Is The Enterprise Cloud

Sep 19, 2010

I have read just about every page about the UEC project, and I now know everything about it, except... WHAT IT DOES! I can't seem to find a coherent example of what it does. To the best of my understanding, it runs a virtual machine across multiple servers. Allowing the VM to use the RAM, CPU, and HDD resourced on all servers involved.

Ubuntu Servers :: Setup Simple File Server In A Native Environment?

Dec 7, 2010

I have two computers on my home lan I am trying to share files between...My desktop which is running Ubuntu Server 10.10 (x64) with a GUI, and my laptop which is running Ubuntu Desktop 10.04. I have tried a million different tutorials regarding SAMBA setup, but they never work.

In addition, most of those tutorials are geared towards hybrid Linux/Windows environment. I do not have any microsoft product in my home. I have created the share on my server, but I'm not sure how to connect to it from the laptop (once again at this point in the tutorials it explains how to access it from a Windows PC). I tried using the menu doing this:

Places-->Connect To Server-->Service Type-->Windows Share (for the server I tried my server hostname and IP) to no avail. Does anyone know of a recent step by step tutorial for setting up a complete Ubuntu environment? Is there a simpler method I can use since I do not particularly need to use SMB protocol?

All I want to do is share my music folder from my server so I can access it (from the same LAN) on my laptop...Arrrghhh frustrating.

Ubuntu Servers :: Setup My Own Mini-cloud Storage System?

Jan 26, 2010

I have collected a number of computers over the years, and now I would like to put them to good use. I considered UEC, but many do not support hardware virtualization and all I really need is storage. Over all the machines, I estimate that I have 4-5 terabytes of storage, all going to waste because each one has relatively low storage space. Is there any way I could setup a redundant storage solution that utilities these machines in a networked system?

Ubuntu Servers :: Enterprise Cloud Services Not Running On Boot?

May 7, 2010

I downloaded the latest 10.4 server CD with the intention of running a small Ubuntu Enterprise Cloud. I am following the directions here: [URL] Ive got 2 laptops that are capable of the tasks assigned to them. Both have dual core Intel chips that are VT enabled, 4GB of RAM, 250GB hard drives. Ill use one ( "server" ) as the front end server running cc, clc, walrus and sc.The other one ( "node1" ) will be the only node controller on my little network. Ive also got another laptop as a client, running euca commands to make instances and what not.These three laptops are connected to a switch. server is 192.168.1.100, node1 is going to be 192.168.1.110, the client laptop is 192.168.1.120.

the server seems to install fine, I select Install Ubuntu Enterprise Cloud, use it as the Cluster, give the cluster a name and 10 IPs to assign, 192.168.1.150-192.168.1.160 After the server is done installing and reboots, I boot the node machine off the CD and again select Ubuntu Enterprise Cloud. It's at this point the install craps out, because it does not recognize a cloud computer on the network.

Indeed, as I go to the server I run

Code:

ps -aux | grep euca

and see nothing running. So I start the eucalyptus service, and run

Code:

sudo euca_conf --list-clusters

and nothing shows up. Ive done some googling, ran some more euca_conf commands, registering the cluster, enabling walrus, cloud and sc. I can access the web gui on the client laptop, then restart the node install on the node laptop. This time it does see the server as a cluster controller, but when it tries to fetch the preseed file, it seems to not know the cluster's IP, as the red box that complains about the lack of a preseed file lists the URL as [URL] ( or whatever the file is called, I dont have the error in front of me. )

Ubuntu Servers :: 10.04 Shutdowns After Idle For A Couple Of Minutes?

Oct 12, 2010

I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing.

Whenever I go to sleep and there's no activity on my servers (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online!

I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active.

Ubuntu Servers :: Apache Reverse Proxy Redirecting To Eucalyptus Cloud Settings

May 26, 2010

I am having a few websites running in a Reverse Proxy scenario on Ubuntu Server 10.04. The configuration is like this:

Code:
|--------------192.168.1.1
| (site1.abc.com)
|
|--------------192.168.1.2
| (site2.abc.com)
|
|
|
|
|--------------192.168.1.3
| (site3.abc.com)
|
|
|
|
|--------------192.168.1.4
| (site4.abc.com)
(Public IP ) |
A-------------------|
(reverse proxy server) |
(192.168.1.25) |
|--------------192.168.1.5
| (site5.abc.com)
|

Except one all websites are running properly and being redirected to their respective domains.
Following is the configuration which I used for each site define on server A a vhost file which contains following

Code:
# ProxyPass / http://<Ip of Server>
# ProxyPassReverse / http://<Ip of Server>

So if I have 5 websites then I have 5 vhost file on the gateway in above diagram A and in each of those file as above root of site is redirected to internal IP. 4 of them are running properly. The fifth website is running on port 8080:/keyword. So in its vhost file on gateway I defined

Code:
# ProxyPass / http://<Ip of Server>:8080/keyword
# ProxyPassReverse / http://<Ip of Server>:8080/keyword
I can see on Lan http://<Ip of Server>:8080/keyword but when from internet I try to see:
http://site5.abc.com
I get redirected to a page is https://site5.abc.com:8443/ and it says

Code:
The webpage at https://site5.abc.com:8443/ might be temporarily down or it may have moved permanently to a new web address. The site5.abc.com has a requirement to be run at port 8080 internally and it is not a Ubuntu server.(Red Hat based server). While rest all are Ubuntu servers including gateway A.
