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?
what kind of network between cloud controller and nodes, is required for a proper cloud installation? I mean, Does all machines needs to be in same network, in same lan, or may be in MAN or WAN ? how much should be network throughput? 1Mbit/sec , 10Mbit per sec, or 1Gbit/sec? I ask because I need to know the possibility of running nodes on different locations.

what cloud computing is and i think it can help me with some of my clients i want to switch my clients from a normal ubuntu server to a ubuntu cloud. as of right now i have to send out a bill to them and if they dont pay i have to shut down there service till they pay. what i would like to do is to have a cloud where i can sell them based on what they use not a set price like it is now. and have them be able to pay there bill on the cloud and if they miss the bill then the cloud can shut off there service till its payed.
i dont know if this is possible and i have looked everywhere and all i can find is info on other businesses billing and now how to set up a cloud to do this. i wish there was some kind of tutorial for this. if anyone can direct me to some good notes/tutorials that would be very helpful. this could be a big changing point in my business if i can do this. it would save a lot of time and cash.
I'm trying to setup my Ubuntu 9.10 laptop to host a small website that I can practice and learn stuff with and I'm a little stuck at the minute.
I have got Apache2 and the LAMP stack installed okay, along with phpMyAdmin and can give my external IP to anyone with the http:// and anyone can view my website that way but what I want to do is have my IP resolve into a domain name like ooloo-website.net but I don't know how to do this.
Is there any way that I can do this like register my IP to a free DNS and domain website without buying a domain or using one of those free ones like ooloo.webhost.net or do I need to host everything myself like DNS and the domain? Can I even do all of this myself?
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!

I have a good grasp on windows server 2003 but I don?t want to pay outrageous license fees for software and services and clients. I am newish to terminal as I only know a few commands. I have no problem installing services for the server edition for 10.04. Its just understanding whats going wrong to troubleshoot. I guess there is you guys and I have good working knowledge of Cisco's IOS's so I understand things like routing tables and interfaces and such for troubleshooting.
Questions I have... Can I install the desktop version of 10.04 and just install the server services? I was looking at the server guide [URL] and would like to know if these can all be installed on the desktop edition without too much trouble. I would imagine one could just use the server edition but I would really want a graphical user environment for some of the activities, if not all that I can. This would be becuase on my skills in the CLI. I priced out a server from Dell. I fits my budget perfectly if I go the Ubuntu 10.04 route. I was wondering if anyone sees any conflicts with the hardware for the Ubuntu OS....

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.

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.
I am trying to install Ubuntu server edition on an old HP XT963 that recently came into my possession. I mainly just wanted to use it as a home file server and print server. I have been running ubuntu desktop on my laptop for a little under a year, but this is my first go at the server edition.
While ubuntu was installing it said "network autoconfiguration failed," I hit continue, thinking I could figure out how to configure it later. After lots of googling I still haven't figured out what exactly is wrong.
Code:

after googling around I made it look like:

View 1 Replies View RelatedI 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.

Is there any way I could setup a redundant storage solution that utilities these machines in a networked system?
View 4 Replies View RelatedI 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. )
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.
