Just tested the new beta release.  It looks like the ipfilter
upgrade finally fixed the out-of-window problem on successive
remote shell and remote file copy requests.  They all seem to 
work now.  I noticed some blocked packets in the firewall log 
during a remote update using the SCO "rdist" utility, but that 
all seemed to work out and not cause any trouble.

Thanks and great job, Manuel!
