Hi Guolin,
Looks to be missing a pair of parens:
checkCommand = ( ReturnsZero(/usr/bin/test "`sysctl -e -n net.ipv4.tcp_abc
2>/dev/null` " = '1') )
^

David,
Good idea.
I tried the following but it fails.
Error messages are:
...
cf:cfengine::/var/lib/cfengine/inputs/cf.groups:102: syntax error
...
The #102 line is the checkCommand class definition line.
Any ideas?
Thanks.

commands?
Hi Robinson,
How about leveraging 'egrep'? For example, I use something like the
following
in my 'groups:' section:
WrongOptLocal = ( ReturnsZero(/bin/sh -c
"PATH=/bin:/usr/bin:/sbin:/usr/sbin ;
mount | egrep 'filer:/vol/vol0/opt/local' > /dev/null 2>&1") )
Use regex w/ egrep to get as specific as you want.
And then in 'alerts:' I have:
alerts:
WrongOptLocal::
"WARNING: System is mounting /opt/local from the wrong filer"

Hi,
If there are any ways to define groups/classes with
the return results of (shell) commands? Currently
there is a function called ReturnZero can be used to
define classes based on exit code, like explained in
the online reference:
ReturnsZero(command)
True if the named shell command returns with exit code
zero (success).
But what I'd like to have is something like the
following:
strCmpReturn(identificationString, command)
True if the named shell command returns with
(exactly) the identificationString(or number).
If there is already a function like the above? If
not, anyone can suggest another way to workaround it?
Thanks a lot.
