So I am trying to change the permissions for my ec2 .pem file with

chmod 400 key_ec2.pem

But afterward I keep getting

-r--r-----  1 Huanqing None   1692 Feb  3 11:26 key_ec2.pem

I am using Cygwin on Windows 8. Is there a setting I need to change?

Weird... also, this `None` group doesn't look very nice. What if you change the group to yours? – fedorqui Feb 03 '15 at 16:39
can you try sudo chmod 400 key_ec2.pem – Sorcrer Feb 03 '15 at 16:40
@fedorqui How do I change the group to mine? – letter Q Feb 03 '15 at 16:40
@Sorcrer It says "-bash: sudo: command not found" – letter Q Feb 03 '15 at 16:41
run cygwin as root user by right clicking the shortcut and click run as administrator,then try ,chmod 400 key_ec2.pem – Sorcrer Feb 03 '15 at 16:43
Type `users` to know the groups you belong to. Then, use `chgrp GROUP_NAME file` to change it. – fedorqui Feb 03 '15 at 16:43
@fedorqui When I type `users` I get nothing back – letter Q Feb 03 '15 at 16:45
@Sorcrer when I type `su -` I get "su: user root does not exist" – letter Q Feb 03 '15 at 16:45

@Sorcrer Thanks so much for the help but that still didn't work. Same wrong permissions are given. – letter Q Feb 03 '15 at 16:46

@QuinnLiu what do you get when you type `id`? It should show all the groups you belong to, together with the numbers. – fedorqui Feb 03 '15 at 16:54
@Sorcrer Your link worked how do I give you points since you answered my question correctly in a comment? – letter Q Feb 04 '15 at 16:40
@QuinnLiu That's all right, Glad I could help to solve your issue. Anyway that answer belongs to someone else give him the point. – Sorcrer Feb 05 '15 at 10:56
