I worked around the problem by running a cron job on a host behind the firewall that gathers the modem's ip address using wget and that itself runs ez-ipupdate. But it sounds as if the 0.0.0.0 trick would save me the wget part. That said, your problem seems to be with cron rather than with ez-ipupdate. I've never had much luck with installing cron jobs on LEAF. Not sure whether it's my fault or not, as I've never looked very hard for a solution. --Eric -- ****************************************************************************** * From the desktop of: Eric House, [EMAIL PROTECTED] * * Crosswords 4.0.6 for PocketPC is out!: <http://xwords.sourceforge.net> * ****************************************************************************** ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
