Re: [Oscar-users] How do you stop login on compute nodes?

[Bernard Li]

I think it is important to educate the users that if they are running 
jobs outside of the batch system, it is going to hurt themselves since 
it slows down the efficiency of the system.  Once you pound that into 
their head, hopefully they'll be wise enough NOT to do that.

I suppose what you could do is to run some cron jobs on the nodes to 
kill off shells (depending on what system you use), but I am not 100% 
certain whether users will spawn shells to run jobs if they are 
distributed through the batch system.

This is an interesting topic though, for sure :)

Cheers,

Bernard

Folks,
        Does any one know or have some pointers to any simple methods to stop
cluster users logging into the compute nodes?  I want to restrict our
cluster users to submit all the work to the cluster via PBS.
Thanks
Frank
