i am using putty not cygwin but this message "the program cannot start because cygintl-2.dll is missing. " not getting it.
I am trying for a password less connection to the server and getting different kinds of difficulties, some instructions on this "quite simplified " for the beginner would be appreciated.
created a public and private key, trying to give permission to the folder gets me this message

    chmod 700 $Home /Users/Name/.ssh  
-- this particular command asks for the *-2.dll file.

so how should i give permission to the folder and file to get automatically authenticated pswd-less.  
Do I require this functionality, I have mixed up all knowledge from putty and cygwin and now good at none being confused which to use.
I found cygwin quite complex to set up, being new I did was afraid miss-leading to system damages which i may be unable to recover.
putty seems simple though lacks functionality (easyness- via cli).
