I created a new EC2 instance using the official CentOS 7 (x86_64) HVM image.

I ran:

yum upgrade

At:

Running transaction
Warning: RPMDB altered outside of yum.
  Updating   : 32:bind-license-9.9.4-14.el7_0.1.noarch                                                                       1/80
  Updating   : selinux-policy-3.12.1-153.el7_0.13.noarch                                                                     2/80

I can no longer SSH into the box :-(

I can establish a connection on port 22, but see nothing more after that running ssh client in verbose mode.

I guess mounting the EBS on another instance is my only means of recovery.

If I do that, what's the easiest way to restore ssh access? I'm not sure whether that update set selinux to enforcing, and whether that would even be the issue here?

Have you tried turning it off and on again ... – Christopher Perrin Jan 14 '15 at 00:51
Actually, that helped! I noticed that prior to restart, the AWS console said "Instance reachability check failed". I thought that fix-by-rebooting only worked for Windows ;-) – Plutext Jan 14 '15 at 01:39
Nice to hear that it helped. – Christopher Perrin Jan 14 '15 at 11:51
