I created two ec2 instances, and was able to ssh into the first two fine. After creating the third, I get this error upon trying to ssh into any of them.

This is what I'm running: ssh -v -i /Users/name/meteor.pem [email protected].###

To get:

I've tried this post's suggestion:

sudo chmod 700 ~/.ssh/
sudo chmod 600 ~/.ssh/*
sudo chown -R User ~/.ssh/
sudo chgrp -R User ~/.ssh/

but the line chgrp -R User ~/.ssh/ gives me the error chgrp: mycomputerusername: illegal group name

I can't figure out what the group name should be. My aws account username? Ubuntu?

I also have no idea what I did to cause this error. Every time I create a new pem I run chmod 600 meteor.pem , so maybe I entered this line wrong and it's causing permissions problems?

Any suggestions about what to try next would be greatly appreciated!

  • Did you actually confirm that the current ownership or permissions are incorrect (using ls -l)? The required group name would normally be your primary user group as returned by the command id -gn or its numeric equivalent id -g. Aug 15, 2015 at 16:30
  • I see that my .pem files have group staff, when I type ls -l. When I run id -gn in my .ssh folder and in my app's project directory, I get staff. I may have misinterpreted your suggestion, but does this mean my problem is not permissions related? Aug 17, 2015 at 14:43
