Question
Setup no password ssh access
Answer
Setup no password ssh access1.From any machine run: host1% ssh-keygen -t dsa
When asked for a passphrase hit enter. This creates a file at ~/.ssh/id_dsa which is supposed to be private and local to that machine, and creates a ~/.ssh/id_dsa.pub file that becomes part of the ~/.ssh/authorized_keys2 files on the remote machine and allows you to ssh from host1 to other hosts. You can use the same ~/.ssh/id_dsa everywhere.
2. From any machine run: host1%cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys2
Add the collowing lines to the ~/.ssh/config file:
StrictHostKeyChecking=no
ConnectionAttempts=15
On any new host, run the commands:
- newhost% mkdir ~/.ssh
- newhost% cp /backup/copy/for/ssh/* ~/.ssh
- newhost% chmod 700 ~/.ssh
- newhost% chmod 755 ~
