I am trying to set up an MPI cluster, following Setting Up an MPICH2 Cluster in Ubuntu tutorial.
However, in step 7, I execute:
cat id_pub.dsa >> authorized_keys
but I am getting:
cat: id_pub.dsa: No such file or directory
What am I missing?
Edit:
gsamaras@pythagoras:~/.ssh$ pwd
/home/gsamaras/.ssh
gsamaras@pythagoras:~/.ssh$ ls
authorized_keys id_rsa id_rsa.pub known_hosts
pwd
?
