		win-ssh-agent, win-ssh-askpass (for the cygwin openssh)


1. Introduction

	With the win-ssh-agent, we can use the ssh-agent (available in
	the cygwin openssh) in the more smart way.

	Normally, we need to start all relevant programs, which might
	need to use the ssh, as child processes of the shell
	(e.g. bash) in which you eval'ed the ssh-agent.  Because, the
	programs must be able to refer to environment variables that
	set by the ssh-agent.

	The win-ssh-agent enables all programs to refer to the
	environment variables of the ssh-agent, i.e. the
	SSH_AUTH_SOCK.  Now, we no longer need to start programs as
	child processes of the shell.


2. Install

	The win-ssh-agent.exe and the win-ssh-askpass.exe should be in
	the same directory (e.g. /usr/local/bin/) .

		For 32-bit Cygwin, you can use the attached
		win-ssh-agent.exe and the attached
		win-ssh-askpass.exe.

		For 64-bit Cygwin, you need to compile sources.
		Follow the section "6. Compile", then do the above
		instruction.

	Install the cygwin openssh by the cygwin setup.exe.
	I confirmed that the openssh-6.2p2-1 worked properly.

	The system wide PATH environment variable must have /bin of the
	cygwin (e.g. PATH=C:\cygwin\bin;... or PATH=C:\cygwin64\bin;...)


3. Run and Terminate

	To run, double-click the win-ssh-agent.exe .

	It asks the pass-phrases.  After you fulfill them, the
	win-ssh-agent stays in the notification area of the taskbar.

	To terminate it, right-click the icon in the notification
	area, then choose "Exit".


4. Behaviors

	After the win-ssh-agent started, it will make the ssh-agent
	automatically start.  And then the below environment variables
	will be set up.

		SSH_AGENT_PID	the process ID for ssh-agent.exe
		SSH_AUTH_SOCK	the socket-path for ssh-agent.exe
		SSH_ASKPASS	the path of win-ssh-askpass.exe
		DISPLAY		:0

	(The terms of set up the DISPLAY environment variable are that
	the DISPLAY have not been set up and also then --no-DISPLAY
	option was not set up at the command line of the
	win-ssh-agent.)

	Once this set up would be done, all application which will be
	started through the Explorer will be able to refer to these
	environment variables, because they are set up into the
	Explorer.

	The win-ssh-agent stays in the notification area of the
	taskbar and deletes each environment variable at the end of
	its life.

	
5. Options of the win-ssh-agent.exe

	--no-ssh-agent

		It stops to start the ssh-agent.  Without this option,
		the ssh-agent is automatically started.

	--no-DISPLAY

		It stops that the win-ssh-agent sets up automatically
		the DISPLAY environment variable.

	-i, --identity FILENAME

		In case using more than one identity file, the
		identity file will be specified by this option.  This
		option can be specified more more than once.

	-I, --default-identity -

		It shows dialogue which asks the pass-phrase at the time of
		start.  This option can be specified only once.

		The same identity files are considerd to be specified
		as the ssh-add with no-options uses.
		(i.e. ~/.ssh/id_rsa, ~/.ssh/id_dsa, ~/.ssh/id_ecdsa,
		~/.ssh/id_ed25519, ~/.ssh/identity)

		In the case of default, -I - is set up automatically.

		This option invalidates -I FILENAME.

	-I, --default-identity FILENAME

		This option works almost as same as -i.  But, it shows
		a dialogue which asks the pass-phrase at the time of
		start.  This option can be specified multiple times.

		This option invalidates -I -.

	--no-default-identity

		It stops that -I - is set in the case of default.

		This option invalidates -I -, and -I FILENAME.

	-e, --exec PROGRAM [OPTION ...]

		After the win-ssh-agent started, it executes the
		PROGRAM.  If the -I option is specified, it is
		executed after closing the pass-phrase dialogue.  In
		the case the pass-phrase dialogue was cancelled, it
		will not be executed.

	-a BIND_ADDRESS

		Bind the agent to the UNIX-domain socket bind_address.  The
		default is $TMPDIR/ssh-XXXXXXXXXX/agent.<ppid>.

	-t LIFE

		Set a default value for the maximum lifetime of identities
		added to the agent.  The lifetime may be specified in seconds
		or in a time format specified in sshd_config(5).  A lifetime
		specified for an identity with ssh-add(1) overrides this
		value.  Without this option the default maximum lifetime is
		forever.


6. Compile


	The ssh-agent.exe and ssh-add.exe must be found in the path of
	the PATH.

	If you want to re-compile, please do make.

	$ make clean && make && make install

	NOTE:
		If win-ssh-askpass.exe cannot run under Windows XP,
		please try the following commandline:

		$ make install-xp
