RE: trouble running commands non-interactively (e.g. via ssh, cron, at)

No idea since I don't administer NT users, but I assume you've tried to isolate this by scripting "other" executables. So is this a 1) system-wide NT / ssh issue, 2) a possible bug in your script, or 3) is something special about these particular .exe files on your server? 

If those NT exe's have proper $? return values on success/fail, I don't see how this could be any different than a cygwin .exe.

I've got DLL version 1.3.6 installed on NT 4.0 SP6.

I'm trying to create/delete user accounts in the domain that the cygwin
box is in.

If I (interactively) login into the cygwin box via ssh, I can successfully
run the "NT Resource Kit" addusers command and the Ms. Exchange "admin.exe"
command to create/delete accounts.

However, If I try to run either of those commands non-interactively
via ssh, they don't work.  The commands return with no effect.

At first, I thought the problem was something peculiar about the
addusers and admin commands.  So, I wrote perl programs to manage the
accounts.  However, the same problem applies to the perl programs - they
work fine when run from an interactive login-shell, but not when run
non-interactively from ssh.

The same problem occurrs when I try to schedule programs via cron or at
- the scheduled programs fail (i don't even know if they run - there's
  no log anywhere that I can find; I just know they don't do what they
  were intended to do).

Any ideas?

Happy Landings,
