> Hello,
>
> a part of our daily administration issue is to check the output of the
> daily_check.sh scripts, sent by every server in our farm. In this
> script all information about the server and processes an so on.. are
> written by executing simple commands like (ps -ef, df -k, netstat -a,
> ifconfig -a, ...). This mails are checked every morning and our
> administrator spends a time of nealy 2 hours to do so. We hope to
> reduce this time by using cfengine.
> That is why I try to understand cfengine and it's configuration. Till now
> I came across some problems and I hope you can help me:

> I was able to configure cfengine to check if all necessary processes are

> how can I check for processes that are not configured... like shell
> processes and so on that aren't allowed to be there?

> My test-system is a linux 7.3 OS. Now another task is to test cfengine on
> NT. I read in your documentation that
> you need an unix emulation like Cygwin or UWIN. So I installed Cygwin and
> compiled cfengine successfully.
> - Now point number one is that the process list only contains processes of
> Cygwin (only bash and ps itself).
> Do you know if Cygwins ps is able to get NT's processes; so that's they
> can be checked by cfengine?

> cfengine:*: Can't stat /cygdrive/c/pagefile.sys in required/disk
> cfengine:*: lstat: Permission denied

> I'm logged in as Administrator and there doesn't seem to exist a root user
