Check for white space within the conﬁguration ﬁles. As a general

rule, using white space can improve readability. One common issue is

my_variable = ( ExecResult(/bin/ls -l) )

In the example above, cfengine is reporting a syntax error on line

39 of the update.conf. It is possible that the error is a whitespace

error from line 38 in the ﬁle.

5. Unable to connect to a cfengine client or master.

# cfrun

cfrun(0): .......... [ Hailing host1 ] ..........

cfrun(0): .......... [ Hailing host2 ] ..........

cfrun:host2: Couldn’t open a socket

cfrun:host2: socket: Connection refused

Check that the cfservd daemon on host2 is conﬁgured and running.

Use /sbin/init.d/cfservd start to start cfservd if it is not

running.

6. “Can’t stat” messages

When running using either cfrun or cfagent you might get “can’t

stat”errors. For example:

host1: Can’t stat

/var/opt/dsau/cfengine_master/master_files/etc/test in copy

Check your master ﬁle repository, and ensure that the ﬁle in

question is available and has the right permissions.

7. “Couldn’t open a socket ”or “unable to establish connection:”errors

cfagent and cfrun can display errors such as:
