can't run devenv through sshd

can't run devenv through sshd

[Derek Lei Liu]

I am relatively new to cygwin world, so please bear with me for any
naive questions. Basically i have 2003 server with cygwin running, i
also have the opensshd running which comes from cygwin package. i can
ssh into 2003 server no problem, but for some reason, i can't run
devenv.exe or devenv.com (the windows build utility) from ssh session.
The same can be run no problem at local cygwin window though. So the
problem is definitely with sshd configuration.

I checked the archive and did checking "whoami", it gives back correct
user name which is the one i used to ssh in.  right now, i am out of
ideas. Following is my sshd_config file and i hope some expert out
there can help me out and i would really appreciate any help on this
matter.

thanks

Derek

  This is a known problem with 2003.  See the thread

  Ah, but see also

  It seems that only ssh'ing in as a local user by password authentication
will work for the moment.  You could perhaps have a try at the suggested
hotfix:

Thanks Dave for instant response. I suspect my problem is different
from what you suggested.  Forgot to mention the symptom of my problem.
The devenv.com actually got invoked and just hang there forever. there
is no error message spilled out. Not sure that make any difference.
Any idea or should i just go ahead to try local user with password
authentication enabled?

thanks

Derek

  Well, that does sound like a different problem, everyone else was getting an
error message at the least.

  It can't hurt to try, but hang on; are we talking about the devenv gui?
Does your sshd service entry have the "Allow service to interact with the
desktop" checkbox enabled in the services control manager?

Re: can't run devenv through sshd

[Derek Lei Liu]

Thanks Dave. I tried the same thing on XP and it works. So it's
definitely something wrong with 2003 server, either with 2003 server
itself or SSHD configuration. I am not trying to get GUI working. The
idea is basically to be able to run remote build on windows (devenv)
from Linux box and through SSH. I would expect something like "ssh
derek@mywindows-pc do-win-build.sh" to work on windows 2003 server.

I checked the opensshd service on my 2003 server. it seems the Log On
property needs some clarification here. I set it to This account:
./sshd_server. the sshd_server is a windows local account. While i
tried to change this setting to Local User. Regardless what i put in
there, the service won't start. Just wonder what should be the right
setting for Log On.

thanks

Derek
