AS the title mentions. I was dumb enough to change the permissions of
home/ec2-user recursively to 777 after which I could not log in. I then detached the volume and then attached it to another instance and changed the permission to 700 recursively of that folder. Now when I try to connect to it using the following command I get the error

Any suggestions on what I could do to fix this problem. I wasted an entire day trying to connect to that instance and get back to the state it was originally in. Any suggestions would be appreciated. Is 700 permission for
home/ec2-user correct ? or should i change it to something else ? Do u think I might be looking in the wrong direction ?
First, fix the syntax error. You say you used:
ssh -iv ~/Amazon-Permission/FooDev.pem [email protected]
This tries to load an ssh private key named
v, which is not what you want. You want the ssh private key named
~/Amazon-Permission/FooDev.pem. Remove the stray
v that got in there somehow.
