cvs problem

[Karl Schmid]

Hello!

I try to commit an edited file from emacs 21.1.1 under RedHat Linux 

When I enter: C-x v v, add a change comment, enter C-c C-c, I get the 
following error message:

You have no controlling tty.  Cannot read passphrase. 
cvs [commit aborted]: end of file from server (consult above messages if 
any)
 
This error obviously has something to do with the CVS and ssh settings.

HOWEVER: When I commit the same file from the commandline, I have no 
problems at all commiting it, because the CVS settings are correct.

We have another server with Emacs 21.1.1 installed. From this server, CVS 
from within emacs works fine. 

My conclusion is that some of the Emacs settings on this machine must be 
incorrect. I have browsed through newsgroups and the manuals, but have not 
found a solution.

Has anyone an idea where I should start troubleshooting or even a 
*solution*?

Thanks!

these work in my setup for both local and external cvs-servers


(add-hook 'comint-output-filter-function
	  'comint-watch-for-password-prompt)

(setq vc-default-back-end 'cvs)

the password is read from the .cvspass file

The problem is the first line.  I strongly suspect that that line
comes from SSH.  The problem is that SSH has no idea what mechanism
to use to ask you for your password.

But you're prompted for a password, right ?
You should either try to get SSH to use `ssh-askpass' (which opens up an
Xwindows dialog box) or else try to make sure that SSH does not need to
get your password, for instance by using ssh-agent (you may have to create
an identity with ssh-keygen etc...).

Does it prompt for a password ?  If so, how ?  If not, why not ?
