Thanks very much to everyone for the many undeserved thoughtful replies after my careless post. What we were seeing was simply very large-scale synfloods (DS3 or greater both times I was involved). The 'garbage' to which I alluded was simply an artifact of tcpdump on the libpcap version of tcpdump. The command used was: tcpdump -s 1000 -x -n Of course, 2000 will show 2000 bytes; the larger you make it, the more it will show you! This will NOT happen with the older tcpdump. Apparently I'm in good company, several others have been bitten by the same bug recently. I guess it's a good thing it got aired publicly, even if I have to wear the dunce cap for a few days. -- John Comeau - Chief Technology Officer Dialtone Internet - Extremely Fast Web Systems 954-581-0097 fax://954-581-7629 jcomeau () dialtoneinternet net http://www.dialtoneinternet.net
