Re: [SLUG] Managing software across a cluster

[Amos Shapira]

Go ahead and check Spacewalk for your particular situation, but personally
when I looked at it, it seemed to be much too complex to setup and use.

I just came across Katello (http://katello.org/), which might interest you
as well if you are eyeing Spacewalk.

In Thunderbird, server settings  for this account

Connection Security:        None
Authentication Method:    Password, transmitted insecurely

I'm not sure what you mean be "ISP lines"
All this is done from home on my own Desktop via my own Naked DSL
account with IInet and their BOB2 Modem.

 look at the encryption settings for the password. You might need to

 Generally send is unprotected except when you send via your ISP when

I should have added that I WAS (am) using iinet's webmail and on the

 Does IINet have webmail? You could use that to verify the password
you 
 are using actually works...

 Thunderbird is not known for mangling passwords.

[SLUG] Cannot receive email

[ch . allen]

A few days I sent the following appeal

"I have just upgraded my old Dell desktop from Ubuntu 10.10 to 12.04
 using Canonical's official disk.  So far I am the only user . 
 When I log in (as myself) I see the standard wall paper but no icons
 menu bars task bars etc.'

That immediate issue is resolved now, following advice from the list.
VMT.

Now I  have another, with email.

I defined my email account on the new version of Thunderbird but
cannot receive any mail.  
I spent a long time on the phone with iinet support trying to sort
this out.  No success.
Each time I try to get mail I get an error message to the effect that
iinet has received and rejected the password.
I can SEND mail from Thunderbird (via iinet).  I just can't receive
mail.

I installed Claws Email to see if I had the same problem.  I have the
same problem.
With Claws, I get an option to look at the log and that says very
clearly that iinet ask for, received and then rejected the password. 

I suspect that Ubuntu is doing something to the password before
sending it.

Any advice?

Another vote for puppet. The more you use it, the more useful
it gets.

Re: [SLUG] Managing software across a cluster

Hi all,

thanks for the suggestions, they were awesome.
Since writing that email Puppet has been suggested to me as well, though 
I will go look into all the suggestions.


Another option I am looking at is Spacewalk, which I may end up going 
with as I just found out that some other Redhat servers around here are 
managed with Satellite.


Thanks again, always get great suggestions here.

Re: [SLUG] Managing software across a cluster

[Jason Ball]

Oddly I actually boot a large cluster off a diskless image, with a local HD
for file caching/work space. The boot image is relatively small
(500MB).   Yes this uses a little ram for the root file system on the
'diskless' node, but provides a single point of change and a reboot to
update the cluster software.

xcat is used to manage the cluster and I highly recommend it.

Just get it all under puppet (puppetlabs.com).

Re: [SLUG] Managing software across a cluster

[miloska]

I used cfengine to do such things (and much more).

Let me know if you need an example configuration as a starting point.

As far as I know cfengine is not part of RHEL, so you need to install
that third party RPM first :)

Puppet and other similar tools can do this for you as well.

[SLUG] Managing software across a cluster

[Steven Tucker]

Hi all,

I have just rolled out a Scientific Linux (Redhat clone) cluster of 20 
nodes plus controller that runs torque for batching and uses a lot of MPI.
My problem is that I periodically get asked to include some library or 
program to help out with some ones research code, and often it is 
something that needs to be installed across all nodes.


On my Mageia cluster I simply run urpmi parallel, issue the one command 
and it installs across all nodes. For those not familiar with urpmi 
parallel, it queries all the nodes asking what rpms are needed to 
install the given software (including all dependencies), it then 
downloads all the rpms to the machine running urpmi, it then pushes the 
appropriate rpms to each node and installs them.


Is there anything like this for Scientific Linux (RHEL) and Yum ??
The closest thing I have seen so far is clusterssh, but its not really 
the same as each node has to download from the repository. clusterssh is 
a general tool for parallel shells.


I am using a Redhat clone for a number of reasons, the largest being I 
was told to and don't really have choice in the matter, so no chance of 
changing distros. Scientific Linux was easy to configure and everything 
seems to work quite well, so I am quite happy with the distro except for 
the lack of a urpmi parallel type tool.


Any suggestions ??

cheers
