[Zope] Packing with cron

[Jason Spisak]

Zopists,

I am attemtping to use cron to pack my ZODB.  I am using lalo's cron
how-to and lynx.  However when I visit
http://myhost:8080/Control_Panel/Database/manage_pack nothing happens. 
Here is the command I am using in Zope 2.1.6:

lynx -auth superuser:superuserpasswd -source
http://myhost:8080/Control_Panel/Database/manage_pack

Is there anything obviously skewed about this?  Has anyone else tried it
with success?

Thanks in advance,

Jason Spisak
