[Server-devel] XS testing for Chinese English XO
Greeting. This is my first message to the list! I am working on getting a XS server working for deployment in China this summer. Manage to do more testing to see if I could replicate problems I had previously. I can repeat the following with both the chinese and english XOs with a 0.52 XS that has yum updated: 1. User name with space (e.g. tk kang) have problems for the moodle account creation. When I click on the tk kang at the moodle interface it say no profile have been created. I check with the moodle admin account and it confirm that an account was not created with the machine serialID 2. When I change back to the normal name of tkkang a moodle account is created and works O.K. 3. Hence chinese names (double bytes) will have the same issue as describe above. 4. Have not solved the problem of not chinese character in the ds-restore view. When downloaded to the chinese XOs machine it display the chinese activity normally. For fun I created video of the XS bootup and my testing environment. http://www.youtube.com/watch?v=kpZBkNWdtIMfeature=channel_page Cheers and hope to provide more test information as we go along. ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Re: [Server-devel] XS testing
At the moment, I am enabling password authentication for SSH. However, root login via SSH will not be possible. So this test would require the installer to log in as admin, for example. He would then su to root with the root password set by the install script, as needed. As far as I know, we don't have a clear plan on how to implement key pairs. For example, the installer is likely to use the nearest available XO to administer the system. I suppose we could use the usb drive to set up .ssh on that XO. However, we wouldn't want the student with that XO to be the server administrator later on. If we shut down password authentication after the install, there is still the question of how a technician would access the server at the school in case of a subsequent problem.

Re: [Server-devel] XS testing
Thanks for your point about the 'headless' server. The install usb must ensure that ssh access from an XO is sufficient to complete the install process. As far as I know all of our installed servers will be headless. This means the first two 'tests' should be changed: 1. Reboot the server and log in as root. 2. From an XO verify that it can connect with the server network. 1. Reboot the server and log in as root from an XO using SSH. I don't think it makes any difference in the implementation if the usb drive is used to install XS at the 'depot' or at the school. At the 'depot', it may be desirable to have the servers boot from the network. As I understand it, this can be done using the same files used to create the usb drive. Incidentally, one point in favor of a laptop as server is that it's battery may come in handy in schools with unstable power.

Excellent idea. Our model is that the installer has a usb drive with XS to install at the school. We hope that the embedded install script will provide a complete configuration including network, firewall, and Moodle. This is one of the possible scenarios, and likely to be common in pilots. In large deployments it makes sense to preinstall the XS image at HQ because - it can be done in parallel - OS install can be network-based - Additional content can be installed via the network - checks that the machine works while there's a good chance you have spare parts too! :-) Which is a long-winded way of saying: we need to take multiple scenarios into account. In some of the scenarios the user may not have root access or shell access. In some scenarios, the machine will be completely headless... The installer should then do things like: 1. Reboot the server and log in as root. 2. From an XO verify that it can connect with the server network. 3. From an XO verify that the 'schoolserver' link on the browser displays the Moodle site page. 4. From an XO verify that the browser can access the OLPC Wiki. 5. Verify that the XO sees ejabberd (telepathy-gabble) 6. Verify that two XOs connected via ejabberd can see and 'chat' with each other. 7. Verify that an XO receives access denied attempting to download an exe file 8. Verify that the XO can log in to a Moodle course with the correct student identification. Good list. Here's my challenge: I think we can do everything in the list without logging in / using the shell console at all on the XS. Naturally, I am hoping for suggestions of additional essential server capabilities that need to be tested (e.g. verifying backup/restore of the journal/datastore, access the library, install an activity). However, we need to be careful to keep it simple and avoid testing features. Agreed. If the tests are simple enough, they can even be performed by a teacher, which means that the local team has a goodtool to use before they send a technician to the field. So we'd have 2 sets: - tests you can run from an XO - addittional tests you can run if you have shell / root access what do you think? m ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
[Server-devel] XS testing
Hi, I think there are several levels of testing, e.g. regression, functional, and stress. I am not planning on anything special for any of these. What I think we need urgently is a simple procedure someone in the field can use to verify an XS installation. It has to be simple and effective, because this person is also bringing up a school-set of XOs. Our model is that the installer has a usb drive with XS to install at the school. We hope that the embedded install script will provide a complete configuration including network, firewall, and Moodle. The installer should then do things like: 1.

Verify that an XO receives access denied attempting to download an exe file 8. Verify that the XO can log in to a Moodle course with the correct student identification. Naturally, I am hoping for suggestions of additional essential server capabilities that need to be tested (e.g. verifying backup/restore of the journal/datastore, access the library, install an activity). However, we need to be careful to keep it simple and avoid testing features. (For example, verifying that Moodle pops up a pdf correctly is not a test to determine if it is running. That test is needed back in the development lab.) Tony Regarding the testing methods, I believe that Tony is hoping to hear that his work creating testing scripts won't be totally orphaned. Oh, is he working on some? Fantastic!
