Null filename on YellowDog

[Chris St. Pierre]

I apologize for cross-posting, but I'm talking to myself on the
newsgroup. :)

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...] 
cfservd: Host students.nebrwesleyan.edu granted access to 
/var/cfengine/inputs/cfagent.conf

Note that there are two spaces between "stat filename" and "from
host".  The problem is that the file to transfer is not getting set
properly at one end or the other; running "cfagent -v -d2" on the
client gives the following:

[...snip...] 
ImageCopy(/var/cfengine/inputs/cfagent.conf,/var/cfengine/inputs/cfagent.conf,+700,-7077)

This is a remote copy from server: lewis 
Transaction Send[t 9][Packed text] 
Attempting to send 17 bytes 
SendSocketStream, sent 17 
RecvSocketStream(2048) 
    (Concatenated 122 from stream) 

That's the point where it freezes.  For some reason, one of the 
arguments to CopyReg is null.  Given that Cfengine is running just
fine on eight other machines with the same exact update.conf file, I'm
thinking that this might be a bug with Cfengine on YellowDog Linux.
Is anyone out there running Cfengine on YDL?  Does anyone have any
ideas about how to solve my problem?  I looked through the code, but
I'm not a C hacker, so I got lost pretty fast.  Thanks for your help!
