I don't get the user's environment variables while in ssh session. Example :

//open up cygwin console
yoni@yonidesk ~
$ env | grep -i ProgramFiles
COMMONPROGRAMFILES=C:\Program Files\Common Files
PROGRAMFILES=C:\Program Files
yoni@yonidesk ~
$ ssh yoni@localhost

Fresh install of latest cygwin, everything else otherwise seems to work.
Any clues ? Thanks.

The email archives is your friend:

I did some googling around for this to no avail. Sorry 'bout that.
 From the conversation you referred me to :  " ... 'ssh' is a secure
shell so it has a minimal environment...."

a. Did this change in one of the newer versions ? We have a few
machines here configured the same way and we never got this problem
before.

It was a change from Cygwin 1.5, yes.


b. What's the reason for "downsizing" the environment variable set ?
If I'm already securely authenticated as X why shouldn't I see
everything X would if he had opened a terminal locally ?

It's fine if you were comfortable with more of your environment seeping through the 'ssh' connection. But your comfort is not really the issue. Exposing specifics about your environment opens any connection up to exploitation. This is true for 'ssh' in any environment. Check the email archives for a discussion of this change if you're interested in more details.

Q: Are you sure?
A: Because it reverses the logical flow of conversation.
