Flooding TCP connection
Every once in a while, when application crashes and leaves an open TCP
connection, data starts flowing full speed back and forth the boxes.
Here's tcpdump output from one occasion where Opera crashed:
=06:56:33.123424 IP webserverip.80 > myboxip.1632: . ack 1 win 33580 <nop,nop,timestamp 859 139667162>
06:56:33.123461 IP myboxip.1632 > webserverip.80: F 838440838:838440838(0) ack 3219133104 win 65535 <nop,nop,timest
netstat says the connection is in CLOSE_WAIT state.
I have a Dell Precision 420 workstation (dual P3 800) with an integrated
NIC:
xl0: <3Com 3c905C-TX Fast Etherlink XL> port 0xdc80-0xdcff mem
0xf8fffc00-0xf8fffc7f irq 16 at device 4.0 on pci2
I'm using packet filter with a basic workstation ruleset.
Any clues? Let me know if you need more information.
