Cygwin: Permissions 0660 for '~/.ssh/id_rsa' are too open.

Environment:

• MS Windows 8.1
• Cygwin 64bit
• ssh keys copied from somewhere and placed to ~/.ssh/

Problem:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Permissions 0660 for '~/.ssh/id_rsa' are too open.

It is required that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: ~/.ssh/id_rsa

Did not work:

• chmod 600 id_rsa
• chmod 700 .ssh
• Playing with Windows security panels
• Setting group to SYSTEM
• Everything else

Solution:

Found on Vineet Gupta's blog http://vineetgupta.com/blog/cygwin-permissions-bug-on-windows-8

chgrp Users id_rsa
chmod 600 id_rsa

Now, all works. Thank you, Vineet!

Cygwin and ANSI terminal

Problem

I see ANSI color sequences on Cygwin.

Explanation

The default Cygwin.bat runs bash in a Window terminal, which does not support ANSI sequences, so you'll see the color codes instead of actual colors:

$ codecept selfupdate

[37;41m                                                                   [39;49m
[37;41m  [Symfony\Component\Console\Exception\CommandNotFoundException]   [39;49m

Solution

Edit the Cygwin.bat and make it look like:

@echo off

C:
chdir C:\cygwin64\bin

mintty -

Now, it will run "mintty", which is a different terminal, and it will show the colors correctly.

Could not open input file: /cygdrive/c/PHP/phpunit (PHP under Cygwin)

The problem:

$ /cygdrive/c/PHP/php.exe /cygdrive/c/PHP/phpunit
Could not open input file: /cygdrive/c/PHP/phpunit

Environment:

MS Windows
PHP
Cygwin

Explanation:

While started in Cygwin, php.exe will be run in Windows environment, which does not know how to translate /cygdrive/c to C:\

Solution:

Use a wrapper script https://gist.github.com/tivnet/8256140

Netbeans 7.0.1, SVN (Subversion) 1.7, CYGWIN and TortoiseSVN

Environment: MS Windows


I upgraded the CYGWIN, and the version of SVN upgraded to 1.7

$ svn --versionsvn, version 1.7.0 (r1176462)   compiled Oct 11 2011, 10:36:16

Everything went smooth with "svn upgrade" of the folders.

$ svn help upgrade: Upgrade the metadata storage format for a working copy.usage: upgrade [WCPATH...]

NetBeans, however, gave me an hour of headache.

Here are my discoveries (things to do are marked in bold)

1. By default, NetBeans uses internal SVN client and not the on specified in Options - SVN command line.
2. To use the command line client, there is an option:
   -J-DsvnClientAdapterFactory=commandline
3. Adding that option to NetBeans config file did not help. Had to add this as a parameter to the shortcut launching NetBeans
4. CYGWIN does not like being called from NetBeans. First, it complains about MS-DOS paths (C:\blah-blah), and when it is fixed by setting CYGWIN=nodosfilewarning, still produces some weird error messages
5. http://tortoisesvn.net/ worked perfectly, however. Do not forget to install the command-line client (which was unchecked in the default setup). You still have to run NetBeans with that -J switch.
