Ssh Resource Temporarily Unavailable



If your OS pre-installed you may want configure ssh-server because you don't want to trust OS maintainer guys:) Server ssh fingerprints are important for device security. To enable SSH on boot please run ' raspi-config '. In menu you will find 'enable/disable SSH' option. This happens after a very long delay. Logging in through ssh works but configuring anything network related using omv-firstaid ends up with the ERROR: Errno 11 Resource temporarily unavailable. I can ping ip addresses but not domains. /etc/resolv.conf just has the ip address of my pi-hole dns server.

Resource Temporarily Unavailable - SSH on EC2 Instance
Posted on: Jun 3, 2020 6:10 AM
This question is not answered. Answer it to earn points.
I recently attempted to SSH into my EC2 instance to update some SSL certs, but am unable to log in to the instance. It previously worked fine, but now I get resource temporarily unavailable when connecting from Putty/WSL. One odd thing to note is that I CAN connect using the EC2 Instance Connect via my browser. Here's what I've tried:
- Rebooted instance
  • Verified that the VPC, subnet, and network ACL are configured per AWS docs to allow SSH connections from my IP (they're all set to the default still)
  • Verified I'm connecting to the correct public IP address
  • Ran the SSH troubleshooting Automation, which succeeded but didn't change the fact that I still can't SSH in to the box

Any ideas/thoughts/comments are appreciated!

When trying to open a ssh connection to a system with a specific account, it failed with 'Connection reset by peer'. Other users can successfully connect with ssh to this system.
Below is an example showing the failed login to node rac2 with the account 'oracle'.

oracle@rac2's password:
Read from remote host rac2: Connection reset by peer
Connection to rac2 closed.
[oracle@mydesk]$ssh root@rac2

The error information can be found in /var/log/messages log on node rac2 :
