Another question we're being asked a lot is: "How do I configure the firewall on my instance?", or, even more frequently, "How come I cannot connect to port XXX on my instance?"
Let us deal with the issue of outbound ports (your instance attempts to contact an external service on a certain port) first. At this point, they all should be open, except the mail port 25. If you need to send mail, you may consider secure smtp (port 465)
For the inbound ports, you have the luxury of configuring them in at least two ways: in the virtual machine itself (e.g. using iptables), or by injecting rules pertinent to your VM into the overall hypervisor firewall rules. Let us look at both of these in detail.
Clearly, dealing with the firewall on the hypervisor level is preferred if you care about performance. If you are restricting the packets on this level, they do not need to be even delivered to your VM before they could be discarded. On the other hand, the process here is somewhat involved, namely:
In the base master images, only ports 22, 80, and 443 are opened for your VM by the hypervisor. If you need to open other ports, follow the steps below:
You'll need to capture an image of your running instance. In the control panel, select your instance and click "select image". This may take up to an hour, depending on the instance size
Once the capture is complete, you will need to find and access your custom image in the image catalog. Make sure that you are logged in; from the image homepage you'll need to click on the content tab and navigate to the file called parameters.xml
Take a look at your default parameters.xml. It should look something like this Take a look, only ports 22, 80, and 443 are open.
Feel free to add the ports that you want open. If you want to open all ports, use this file as your baseline, for instance
Upload the modified file (replacing the old parameters.xml) and make sure that you save the new image.
Provision a new instance from the modified image. Once the instance is active, new firewall rules will supercede the old ones.
Changing the iptables rules is quicker. By default, the iptables firewall is not enabled in the instances. To learn about iptables, visit the project homepage. To enable it, you could do this, for instance:
Become root (sudo su-), navigate to /etc/sysconfig and edit the file called iptables.
Add or remove the lines as desired; once you're done, start the service: service iptables start
Check that the service is running and the rules in effect: service iptables status

We're currently performing emergency maintenance on the provisioning portal and have temporarily disabled it. Please stay tuned - it should be back up shortly. Your instances should remain accessible. Thank you for your patience.
We are currently experiencing network issues, affecting some customer VM instances, or in some cases, the customers ability to create new instances. The team is working to resolve; connectivity should be restored soon.
If you're located in San Francisco Bay Area, you're very much welcome to attend the meetup on the IBM Developer Cloud Beta.. It's going to take place on January 28th in Foster City. More details here: http://www.meetup.com/ebcloud/calendar/12071541/
For all of us performance freaks out there, here's a quick guide on how to get Nginx to run on a fresh SUSE instance of the beta.
First off, Nginx is a very fast web server / reverse caching proxy, and you probably don't need to worry about installing it unless you really need that extra performance edge over the "standard" apache. Here are the steps:
Grab a fresh instance of SUSE from the beta web site, and ssh in as idcuser. Not sure how to do that? Read the How-to Wiki.
Get Nginx -- either from the official download area or just do something like wget http://sysoev.ru/nginx/nginx-0.7.64.tar.gz
Extract and untar -- e.g. gunzip < nginx-0.7.64.tar.gz | tar xvf -
Become root, e.g. sudo su -- fire up Yast -- e.g. yast2 then go to Software -> Software Management and install the following packages: openssl-devel , gcc, pcre-devel, zliv-devel Exit Yast and exit the root shell -- e.g. exit
Go that directory you've extracted nginx to , e.g. cd /nginx-0.7.64
Run configure -- e.g. ./configure
Install the thing -- e.g. sudo make install
You're all set. nginx is installed under /usr/local/nginx and you could start it up -- e.g. /usr/local/nginx/sbin/nginx and/ or edit the config file located under /usr/local/nginx/conf/
While some folks don't mind using WinSCP to transfer files between your their work machines and their instance, mounting the instance as a network drive in Windows makes it just that much easier to work with -- the drive is just there for you.
typically used to mount a Linux drive to Windows. However, the beta is a public
environment, so traffic to it goes over the Internet, and security should be a
consideration. Instead of Samba, let’s use SSH as the underlying transfer
layer—it’s configured on each of the available software images.
Enter Dokan, a FUSE and SSHFS implementation for Windows. No server-side configuration required; all you need is an active instance, its ip address and your private key. If you need help with those, you can always check with the beta user guide or watch one of the tutorial videos.
Here's how to set up and confugure Dokan on your Windows machine:
Download and install .NET unless you already have it installed
Download and install Dokan SSHFS next. We're ready to connect to our instance now.
Run Dokan SSHFS and you should see a window similar to the one shown below. Give your connection a name, specify the ip address of your instance and the user name that you wish to connect as. All instances come with the idcuser account configured, so we're using that in the screenshot:
Under the Identity section, specify your unmodified private key that you downloaded from the beta web site. The name of that file should be similar to ibmcloud_youremail_rsa. Note: Don't use your converted Putty key - it just won't work.
Specify the directory you wish to mount -- notice that we used the idcuser home directory to avoid any permission problems. Give your mount a drive letter, click Connect, and if you see this tiny window. . . . . . you know that you're all set. Contratulations! Now you can use Windows Explorer to work with your new drive :)
Please join us for the upcoming webcast entitled IBM Smart Business Development and Test with Linux on the Cloud, where we'll discuss IBM vision of Cloud computing, our Linux strategy, and how they come together in the beta implementation of the Developer Cloud.
Hello everyone; we've made a few really cool additions to the beta in the past few days.
First off, there's mountable cloud storage that makes a fine addition to the "ephemeral" storage space that already comes with your virtual machine instances. The Cloud storage won't go away when your instance does, and you can attach it to a different instance or mount it across multiple instances.
Second, we've made available the IP address reservation system. A reserved IP address could be assigned to an instance, or dissociated from it when this instance de-provisions and assigned to a new instance. This is a step on the trajectory of keeping your topologies consistent and applications available.
There are numerous enhancements to the system, from the user interface to the back end. We hope that you will find the beta more usable, powerful, and stable.
Additionally, we invite you to sample the features that we released in the past several weeks. There's the RedHat OS image, much requested by the user community, and then there's the documented and comprehensive RESTful API, which allows you to interact with the beta web site programmatically (see some samples here). We've been working on providing additional documentation for the system and its images as well. Check out the new How-to Wiki and the Getting Started Guide for the image creators, just to name a few.
