Not sure what you would need I pick up our files from commonupdater/current and just require amcord2000 and endpcnt_1000 plus sitestat.xml and catalog.z. These are for updating our PC's, I just use Linux to store and distribute the files.
We have both windows boxes and RHEL boxes that I update. For the Windows boxes we have been downloading from commonupdater.
For the RHEL's we have been updating using a single file from the /pub/datfiles/english folder. Last week I got avvdat-9279.tar for example. That gets copied into a folder on the RHEL and unziped, 4 files. Today in the /pub/datfiles/english folder there are no files.
