Windows CHMOD 600

Question

I'm trying to connect to Amazon EC2 using OpenSSH in windows but I need to set the permissions of my key file.

What is the windows equivalent of CHMOD 600?

I've googled extensively and found only blogspam.

EDIT: Windows 7, using DOS.

Answer 1

I realize this is somewhat old but I just found the solution for myself in Windows 7. And it looks like this question went unresolved. I had all of the same errors including Cygwin missing cygintl-2.dll on chmod as you noted in the comments.

After extensive research and not finding any answers I ran:

C:\Users\mztriz\.ssh>ssh -v

OpenSSH_3.8.1p1, OpenSSL 0.9.7d 17 Mar 2004 usage: ssh [-1246AaCfghkNnqsTtVvXxY] [-b bind_address] [-c cipher_spec] [-D port] [-e escape_char] [-F configfile] [-i identity_file] [-L port:host:hostport] [-l login_name] [-m mac_spec] [-o option] [-p port] [-R port:host:hostport] [user@]hostname [command]

As you can see the version of OpenSSH I was running was quite outdated. However, I didn't know this because a quick google search of OpenSSH for Windows returns this old version.

After looking into the versioning I found OpenSSH for Windows 6.9p1-1 in the downloads section of that website.

This newer version of OpenSSH seems to fix all of the issues you mention.
