Strange connection problems with YellowDog

[stpierre]

I'm in the process of bringing Cfengine up on a number of diverse
hosts.  It's working fine on most of them, but it's not working on our
two YellowDog Linux (PPC) machines.  When I try to run cfagent on the
client ("students"), I get this:

# cfagent -v
[...snip...]
cfengine:: Strong authentication of server=lewis connection confirmed
cfengine:: /var/cfengine/inputs/cfagent.conf wasn't at destination
(copying)
cfengine:: Copying from lewis:

It hangs at this point until I C-c it, which gives me:

cfengine:: Received signal 2 (SIGINT) while doing [pre-lock-state]
cfengine:: Logical start time Thu Feb 23 08:06:08 2006
cfengine:: This sub-task started really at Thu Feb 23 08:06:08 2006

Starting the server ("lewis") with -d2 gives me the following output:

[...snip...]

Note that there are two spaces between "stat filename" and "from host",
suggesting to me that some variable is not getting expanded.  Here's
the update.conf I've used on all of the computers I'm putting Cfengine
on; it's worked on the other seven without a problem:

control:
        actionsequence  = ( copy )
        domain          = ( nebrwesleyan.edu )
        workdir         = ( /var/cfengine )
        policyhost      = ( lewis )
        master_cfinput  = ( /var/cfengine/inputs )

copy:
        $(master_cfinput)
                dest=$(workdir)/inputs
                r=inf
                mode=700
                type=binary
                server=$(policyhost)
                trustkey=true
                exclude=*.lst
                exclude=*~
                exclude=#*

processes:
        new_cfservd::
                "cfservd" restart "/var/cfengine/bin/cfservd"
        new_cfenvd::
                "cfenvd" restart "/var/cfengine/bin/cfenvd"

Here's my cfservd.conf; "students," the client, is 10.12.1.6:

control:
        domain = ( nebrwesleyan.edu )

        AllowConnectionsFrom            = ( 10.1 10.9 10.8.3.2
10.12.1.6 )
        AllowMultipleConnectionsFrom    = ( 10.1 10.9 10.8.3.2
10.12.1.6 )
        TrustKeysFrom                   = ( 10.1 10.9 10.8.3.2
10.12.1.6 )

   any::
        IfElapsed = ( 1 )
        ExpireAfter = ( 15 )
        MaxConnections = ( 50 )
        MultipleConnections = ( true )
        cfrunCommand = ( "/usr/local/sbin/cfrun" )

admit:
        /var/cfengine/inputs    10.1 10.9 10.8.3.2 10.12.1.6
        /var/cfengine/master    10.1 10.9 10.8.3.2 10.12.1.6

Does anyone have any ideas on what might be happening here?  I've
thrown every diagnostic I can think of at this problem, and haven't
gotten anywhere.  Thanks for your help!
