how do I SSH into a cluster node?

Hi,

There is a 24node beowulf cluster. I was recently added
on into the gateway using 'adduser'. I can access the
gateway, but not the nodes!

The administrator can SSH into the nodes with his
login and passwd...but not me. Why?

We are the
only 2 users at present. The admn is a newbie and so
am I....How do we overcome this?

Do reply asap.

Thank you

you have to be a *user* on the remote machine I believe. If you typed:

$ssh 192.168.1.1 #use remote node ip here
As user *bignate*, but bignate is not a registered user on that node then it will not allow access. I am not positive but this will get you looking in the right direction.

Hi BigNate,

Thanks for the reply.

I am not a user on the remote node.
How do I make myself a registered user there?
using adduser???

Is there a GUI-useradd, which can not only make me a
user in the gateway, but also simulatenously make me
a user in all the nodes with the same login and passwd?

Try setting up a central authentication system such as ldap and having all nodes authenticate to that.

hmm...I am not sure how you could make yourself a user on all systems at once...I know it does not sound like fun, but my limited knowledge would make me go to the nice admin and ask him to ssh into each machine and add me there.

see
$man adduser # for details
