Try to add /usr/local/bin to exec-path, not load-path.  (load-path is
for *.el and *.elc files, that is Lisp files.)

Or make sure that /usr/local/bin is listed in $PATH at the time when
you start Emacs.  (If you start Emacs from a button in the KDE panel,
then it can be difficult to find out whether the directory is in
$PATH, and if it isn't, how to put it there.  I never could figure
that out.)

Thanks, but that does not seem to work. Changing .emacs file does not change
the propensity of emacs to look for ssh-askpass in /usr/bin, and my path 
lists
both /usr/bin and /usr/local/bin before running emacs (although /usr/bin 
comes first).

That's because the /usr/bin/ssh-askpass path has been hard-coded somewhere,

either an executable or an Emacs Lisp file.

This will depend upon the OS and, in the case of Linux, the 
distribution.  On my system:

# echo $SSH_ASKPASS
/usr/libexec/openssh/gnome-ssh-askpass

Seeing this and reading the askpass section of the ssh manpage and the
doc distributed with the package leads me to believe/guess that
ssh-askpass is used in an X (or other GUI) environment.  If you're 
doing the emacs cvs call in a GUI, this could be the problem.  Try doing 
it at the console-- i.e., go to runlevel 3 or, in X/Linux, do a 
Ctrl-Alt-F2 and run it there.  

So which OS are you using?

There is no way to go to console for me, as I am always logging in to this machine from another.

Try: env | grep ssh-askpass
and: env | grep /usr/bin

Do you have openssh installed?  Doing "whereis openssh" should tell you 
and may even tell you where ssh-askpass is located.  If you haven't 
updated the database in awhile, do updatedb first.

  Actually, I am also trying
to do the same. I have a remote repository, behind a firewall, and I can
connect it to it
using command line cvs, e.g. by saying:
setenv CVSROOT :ext:apaydin@robo:~/cvs_repository

but then when I try to use cvs within emacs, I get the error:
/usr/bin/ssh-askpass could not be found.

ssh-askpass is actually in /usr/local/bin,
and I could not find how to tell emacs where to look
for ssh-askpass. Simple add-path to .emacs in the form of:

(setq load-path (cons "/usr/local/bin/" load-path))
did not help.

Trying the solution suggested by Andrew Taylor requires setting the
CVSROOT as :pserver:apaydin@robo:~/cvs_repository
however then cvs login does not work, as connection is rejected by robo
since it is a firewall.

I was wondering you know of any solution for this case.

Thanks,

emacs cvs over ssh question

[David B]

Hi

I am trying to use the CVS functionality in emacs on Linux (RedHat 9).
I can connect to my repository over SSH and perform all tasks from the
shell, but when I try to do the same tasks from the emacs menu, I get
errors.

Error number one:
Message: ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory
Message: Write failed: Broken pipe

This is resolved by installing X11-ssh-askpass, but this then leads to
a second error relating to failed authentification keys (cant remember
exact sytax- on a different box at the moment)

ssh version is
OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f

emacs version is
21.2

I have searched the web quite extensively, and have found many
pointers that suggest that cvs over ssh is possible in emacs, however
there is no concrete documentation in the pertinent places (emacs FAQ,
pcl_cvs faq, openssh.org), and the snippets that I have gained from
browsing google are promising but incomplete.

So- how does emacs access remote cvs repositories that use ssh
authentification?

Dave

Don't know if that is the solution you want, but you could try setting
up ssh authentication using rsa keys instead of a password, that way you
won't have to give a password (this is what I do, but I havn't tested it
with emacs yet. I'm also not using the standard ssh port, which makes
things even harder).
