If it's Linux or *BSD, are there extended file system attributes set on /usr/bin/cu and /usr/bin/rsh? For linux, type in lsattr /usr/bin/cu and see if there are any flags set. If the immutable bit, or the append only bit is set, it may cause this error. For more information, see the man pages for lsattr and chattr. I can't remember the command for the BSDs right now, but I'm sure someone else can chime in with that info. Steve Bremer
