RouterSyslog

RouterSyslog is a simple Syslog server designed to display system events from your router. New messages are displayed as bubbles in the system tray, or can be automatically saved to text files broken down by day.

Additional features include online WHOIS lookups of domain information and owners, finding WAN IP addresses, and performing DNS queries. This makes the program suitable for users who want to keep track of router activity or need a tool for debugging problems.

The application does not need to be installed - it can be run directly from a USB drive, so you can always have it handy.
