When we use to run Knife ssh to run chef-client on particular node and SSH is not enable for that node . Then Knife ssh get hang out.
Is there any solution to come out from hang state.
Did you try --ssh-timeout option ?
How long did you wait?
Most SSH client configurations have a very generous SSH timeout set. You might review your /etc/ssh/ssh-cient.config, or $HOME/.ssh/config settings.
Now, me? On hosts that are doing “knife ssh” a lot, I review such settings. I also set up $HOME/.ssh/config do disable the “known_hosts” file, so I get no errors about changing host keys. It’s particularly handy if you’re replacing hosts frequently in a small address space. The setup is described at https://linuxcommando.blogspot.com/2008/10/how-to-disable-ssh-host-key-checking.html
