1)
ddclient: Used to periodically check the router's WAN IP address and update it with
DynDNS if it has changed.
2)
Linksysmon: Used to log activity from the router. I have a linked table set up in Microsoft Access that points to the linksys.log file; I can keep all of the logs in a database for future reference. I wish this logging program supported the firewall logs for the BEFSX41 (maybe I'll get a reply to my email).
