[Rocks-Discuss] SSH to nodes as a new user

[Shamil CM]

Hi,

I am using Rocks 5.4.3. I created a newuser using,
useradd user
passwd user
rocks sync users

But I cannot ssh into the compute nodes (which i have configured as
vm-containers). I tried to run an mpi program but its still asking for
password.

mpirun -np 2 -machinefile machine a.out
user@vm-container-0-0's password:

When I try normal ssh these are the debug messages.

$ ssh -v user@vm-container-0-0
