LAB 5.5
Anyone else who had issues with lab 5.*???
I'm trying one by one and so far, with the help of the guides here, resolved till lab 5.5 where for this:
5. Now try some commands withparallel-sshto the local machine:
6. $ parallel-ssh -i -h ̃/ip-list date
7. $ parallel-ssh -i -h ̃/ip-list sudo timedatectl
8. $ parallel-ssh -i -h ̃/ip-list sudo hostnamectl
I get error:
cloud-engineer-student@ubuntu:~$ parallel-ssh -i -h ~/ip-list sudo timedatectl

Cloud_Engineer_student@192.168.1.100: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
Is there any other file (perhaps config) that I need to alter with the correct parameters etc.??

Try generating ssh key without having to input the passphrase. Then copy these to the remote hosts via ssh-copy-id.

As rranay suggested, remove the need for passwords via
ssh-keygen
thenssh-copy-id
to target machines.Or, as parallel-ssh suggested, re-run it while including the
-A
option to get prompted for passwords (a less-optimal solution).0 -
Using passphrase on the ssh keys protects someone from using your keys. Without the pass phrase, your key could be copied to another system and used if permissions allow it. Best practice is to use passphrases, however you will have to enter the passphrase to use the key.
In a lab environment it is common practice to not use passphrase on keys. Many applications have to be informed you are using passphrases .
The man pages ssh-agent and ssh-add may be of interest as well.
