Hi,

I want to generate bro reports from tcpdump packet capture files. Those files were captured from different networks. So:

bro -r file.pcap will generate generate log files:

alarm.log  
conn.log  
notice.log  
weird.log

When I run site-report.pl, I get

No connection data found for the time period specified.  
Unable to create a report.

What does this error mean? Note that the packet capture files maybe several days old.
