I have virtualbox installed on a Mac OS X Catalina host. I have got the Centos 9 guest os running on virtual box. For centos, i have used NAT in networking options, and mapped 2222 to 22. I cannot ssh from the mac os to the centos. Also i note that both host and guest have same ip in ifconfig. But this seems to be not a problem for the demo i am trying to replicate (Puppet course on udemy)

Already tried: Started sshd on the guest os

sudo systemctl start sshd

Added ssh to firewall

sudo firewall-cmd --zone=public --permanent --add-service=ssh
sudo firewall-cmd --reload

Added PermitRootLogin yes to /etc/ssh/ssh_config

Restarted: sudo systemctl restart ssh

Enabled remote login in the Mac OS x

ssh command goes like this in verbose mode:

ssh -vvv [email protected] -p 2222

I'm quite sure your CentOS 9 VM doesn't have 127.0.0.1 as an IP address. Please try to use the IP of the VM with SSH.

@vautee the ifconfig shows that IP. Pls see screenshot: https://imgur.com/qFqvOZw

There should (read: needs to be) also be an IP address bound to the enp0s3 interface. Without that, you cannot continue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
