problems with versioning on windows, with ntemacs, cvs, and ssh

problems with versioning on windows, with ntemacs, cvs, and ssh

[Phillip Lord]

We seem to be having terrible trouble getting VC (and pcl-cvs) working
on NTEmacs. It's running cygwin as its shell, and CVS as the
versioning backed. An added complexity is that repository access is
via ssh. 

This works from an internal shell within emacs, although it prompts
for a password (I presume emacs can cope with this? I seem to remember
on redhat, I get a gnome window popping up from ssh, which isn't going
to happen on windows). 

In almost all cases VC, or PCL-CVS seem just to hang. 

Has anyone got any experiences with this? Have you got VC/cvs/ssh
working under NTEmacs?


Cheers

Phil

I think you're presuming wrong: make sure that ssh does not
prompt for a password.

yes. I'm using keychain, which is part of the cygwin packages, 
to start and keep an ssh agent which prevents from password querying.

when you can commit from the cygwin shell without password entry, 
emacs vc should work, too.

Ah, okay. 

I shall investigate this then. Hopefully this is the
difficulty. Thanks!

I'd not heard to keychain before. It looks nice. Even better is a
series of articles about how it and ssh-agent works. This security
stuff makes my head go around in circles, and I've never managed to
get the ssh-agent stuff working. Now maybe I'll be able to. 

Thanks for the help.

the author of keychain has written a series of articles, take a look at
