cfrun on "User defined module"

[Harish Chauhan]

Hi,

My "cfrun.hosts" file looks
like as shown below:

------------------------
domain=my.x.com
outputdir=/my_dir
maxchild=10

<host1>        
--just
<host>        
-- just
<host3> 
<host4>
------------------------

where  <host1> and <host2>
belongs to soft class defined by "aix_5_1" but <host3>
and <host4> belongs to logical cluster which is identified by the
user defined module.

when I execute the command  "/opt/cfengine/bin/cfrun
-T -- tidy  --<logical_cluster_name>, I don't get the right
results.

I want to execute "tidy" opertation
on my logical cluster machines only. Can any body suggest the way to to
that?

Thanks in advance.
Regards, Harish

Are multiline shellcommands a 2.x feature? I'm still using 1.6.5
and cant seem to get even a simple multiline shellcommand to work.

Can you share how you use Text::Template in your cfengine setup? I have
been wanting to do this. I have not attempted anything yet.

I can actually do each of your examples with my current setup, in 
a manner of speaking.  The perl stuff I can do because I'm using perl's
Text::Template on my cfengine config files before I send them out 
(server-side).  The shell stuff I can do in the shellcommands section
(client-side).  I might also be able to do perl one-liners with 
shellcommands too.  
                
Sorry to all on the list if it sounds like I keep harping on the 
Text::Template, but sometimes, it is the answer to the question :).  

                
Mark, is there a way to do here-documents as input to 
shellcommands?  eg, something like:
-------------------------
shellcommands:
                
any::
                
                 <<EOT
....perl code here...
EOT
                
                 >
"perl"
-------------------------

                
...where "perl" is the shellcommand, > is redirection, and
the 
<<EOT EOT stuf are the here document markers.  The would also
achieve the 
functionality that this guy wants.  

[examples snipped]

> It might help reduce the cruft of little scripts which tend to appear

I have a directory one my central server called ..../local/bin and 
use the cfengine copy stanza to copy things from there to each individual
machine as appropriate.

Hi,

How can I enable cfengine to pre-append hostname in all the log lines.
This will help in greping for a specific error in the log along with the
hostname .

Any ideas ?

Looking forward to your reply...

Regards, Harish

Funny, I didn't see this in the cfengine-Reference info page, but I
pulled it out of another config.

control:

                
OutputPrefix = ( "cf:$(host)" )

This is very nice! I have been wanting a way to reclaim those wasted
columns in mailed cfexecd reports. It doesn't seem to like an empty
string value though ( "" ) (or rather, it uses the default if
you set it
to such a value) so the best I have been able to get is:

OutputPrefix = ( a )

    a: Executing script...

rather than

    cfengine:hostname:: Executing script...

Those columns are valuable!

This variable is there in the reference under "Special variables".

    http://www.cfengine.org/docs/cfengine-Reference.html#Special%20variables

Maybe it should also be under the section for cfexecd, as that is what
you are configuring with it.

Thanks for pointing it out.

I know this list gets a lot of questions about the 'editfiles' 
functionality, and I really have looked hard at the docs before posting
this.

I have found that the approach described by Jamie Wilkinson 
(http://www.shipyard.com.au/articles/sysadmin/cfengine-configfiles.py)
works for me, but I suspect there is a better way.

Should it really take me 9 lines to code 'Make sure SyslogFacility is 
set to AUTHPRIV in /etc/ssh/sshd_config' as he does it:
---
       BeginGroupIfNoLineMatching '^SyslogFacility.*'
         Append 'SyslogFacility'
       EndGroup
       ResetSearch 1
       LocateLineMatching '^SyslogFacility.*'
       BeginGroupIfNoMatch '^SyslogFacility AUTHPRIV$'
         ReplaceLineWith 'SyslogFacility AUTHPRIV'
       EndGroup
       ResetSearch 1
---

If any of you cfengine gurus wish to share a better idiom, I would 
appreciate it.

thanks,
James

Subject: something wrong with time classes

I'm trying to set up a time class that runs every two hours.  So far,
I
have:

# TIME DEFINITIONS
t_on00 = ( Min00_05 Min05_10 )

t_everyhour_00 = ( t_on00 )

t_on15 = ( Min15_20 Min20_25 )

t_on30 = ( Min30_35 Min35_40 )

t_on45 = ( Min45_50 Min50_55 )

t_on00::

    t_every2hours_00 = ( Hr00 Hr02 Hr04 Hr06 Hr08 Hr10 Hr12 Hr14
Hr16 Hr18 Hr20 Hr22 )

The goal is to define a class that will only run on even hours, between
:00
and :10.

However, it's not working.  I have a block of code that is called
via:

_fileperms._glsamakerserver.(t_every2hours_00|run_glsamakertest)::

But it never gets executed automatically.  Only if I run cfagent
-Drun_glsamakertest. (I've ensured that cfagent is executing at the correct
times)

I obviously have something dorked up with the time classes, but I don't
know what.

Any help is appreciated.

How are you running cfengine in the background?

Via cron, or cfexecd -g? If you're using cfexecd, whats the schedule
set to?

So, assuming that you run exactly at 00 in cron, you want

 t_on00.t_every2hours_00::

Another way (if you don't know when the agent runs) is to use ifelapsed
locks set to 120 minutes.

   Hi:

   2 questions... :-)

   One is if there are some option to force cfengine to use IP numbers,
not the hostname...

   and two: I_m trying to use the methods sequence but the example
that
I found on the reference manual doesn't work...

   I use cfengine 2.1.3 over Solaris 5.8.

   Anybody knows why?

   Thanks,

Adolfo Abalo
