Hi Bob,
USERLIST is not available in 0.93.1 (0.93.1 is a bug fix only release...)
And my code only creates user accounts for the login names specified by
USERLIST, the authentication method for StarCluster on EC2 is not implemented
yet - in fact for my use case (running Open Grid Scheduler/Grid Engine
testsuite on EC2 on demand) I don't even need real users to logon.

Hi,
Thanks for the bug fix for addnode. I was suffering that without realizing what was going on.
So is this USERLIST feature in 0.93.1?

Caius,
Let us know how you want StarCluster to setup users for you automatically.
I am modifying & extending StarCluster to automatically run the Grid Engine testsuite for the Open Grid Scheduler release builds. Our testsuite requires the cluster to have multiple users, so instead of manually setting up instances to run the testsuite everytime we release something, I am going to fully automate the whole process - and with that we don't even need to buy machines that sit here idle most of the time for the build process.
Anyway, enough background. I added a new config option, "USERLIST", to specify the list of users to be created by StarCluster when it bootstraps the cluster. For example in the config file:
USERLIST = rayson,ana
2/2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 100%
>>> Creating cluster user: rayson (uid: 1002, gid: 1002)
2/2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 100%
>>> Creating cluster user: ana (uid: 1003, gid: 1003)
rayson_at_node001:~$ qstat -u "*"
job-ID prior name user state submit/start at queue slots ja-task-ID
-----------------------------------------------------------------------------------------------------------------
17 0.55500 sleep rayson qw 01/13/2012 02:39:18 1
18 0.55500 sleep rayson qw 01/13/2012 02:39:18 1
19 0.55500 sleep rayson qw 01/13/2012 02:39:19 1
20 0.55500 sleep ana qw 01/13/2012 02:39:25 1
21 0.55500 sleep ana qw 01/13/2012 02:39:26 1
22 0.55500 sleep ana qw 01/13/2012 02:39:26 1
23 0.55500 sleep ana qw 01/13/2012 02:39:26 1
24 0.55500 sleep ana qw 01/13/2012 02:39:27 1
25 0.55500 sleep ana qw 01/13/2012 02:39:27 1
26 0.55500 sleep ana qw 01/13/2012 02:39:27 1
27 0.55500 sleep ana qw 01/13/2012 02:39:27 1
28 0.55500 sleep ana qw 01/13/2012 02:39:28 1
29 0.55500 sleep ana qw 01/13/2012 02:39:28 1
But then, the users created don't have direct access to the cluster from outside of SC.
To provide direct user login, we can do what Justin mentioned in his previous email...
So let us know how you want your users to log onto the cluster, and we will see if it makes sense to add the authentication method into StarCluster.

Hi Caius,
Currently there is no mechanism to create multiple users on the cluster, however, it's not all that difficult to do via a StarCluster plugin[1].
As Rayson kindly pointed out to me, this is something that comes up from time to time so I'm considering building it into StarCluster, however, I'm not sure whether it would be built into the "core" or delivered as a plugin...
Before I get into details how do you expect to give users access to these accounts? Would you want to pass around usernames and passwords or would you want to have SSH keys generated that you could hand to all users (or both)?
