DSAU (aka "cfengine")

[David Harwood]

Hi,

I am trying to set up DSAU for the first time. I've successfully configured the "cf.main" file and my initial testing has worked OK.

Currently, I have a class called "vmguests" which has 2 servers assigned to it.. i.e.


classes:

any::

#
# Add the class 'dsau' so we can setup cfengine in the specific manner
# that DSAU requires. This will work on any DSAU supported operating
# system type when the main DSAU directory is in place.
#
dsau = ( FileExists(/opt/dsau/sbin) )
# Example class to manage a set of web servers
# web_servers = ( server1 server2 loadbalancer )
vmguests = ( vmguest1 vmguest2 )

As I have a hundred or so vmguests in total, I would like to know if it's possible to have the vmguest names in a file that can be read into this variable rather than having to add them directly into the "cf.main" config file. Everything I've tried up to now has resulted in an error message...

Does anybody out there know if this can be done and if so, how?

Thanks in advance

To include a list of hosts from a NIS netgroup, you use the `+' symbol, or the `+@' construction. For example:

groups:

science = ( +science-allhosts )

physics = ( +physics-allhosts )

physics_theory = ( +@physics-theory-sun4 dirac feynman schwinger )

Unfortunately, we don't use NIS... thanks for the response though.

What do you use?

[David Harwood]

We don't use anything other than standard HP-UX. Name resolution is provided via a separate DNS server.

Well I guess you might be able to just use /etc/netgroup as long as /etc/nsswitch.conf contains a line with:

netgroup: files

look at the man page for negroup for details.

I'd then expect the syntax mentioned above for NIS to work for you...

sorry, obviously:

> look at the man page for negroup for details

should have read:
