I would like to ask the help of people who have cflowd up and running
on thier boxes and are
receiving flows. I have install cflowd on a PIII 450 RH Linux 7.1 box
with 256MB and have yet to
receive flows even though I am currently getting no error messages.
Whenever I do a tcp dump The
only communication that I see between my routers (7507, 6509 w/ msfc)
and my collecter are snmp
requests and responses. However I was told that if I run 'tcpdump -n
udp port 2255' (2056 is the
port that I am using to recieve upd flows) i should see something
similar to this:
collector# tcpdump -n udp port 2255
tcpdump: listening on all devices
12:11:29.953100 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
12:11:29.965310 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
12:11:29.967780 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
12:11:29.985854 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
12:11:29.998673 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
12:11:29.009464 10.0.0.1.1868 > 10.0.0.2.2255: udp 1168
but I do not.
When I do 'netstat -an' the tcp port is listening but not the udp port.
Is this regular or is
there a problem here? Any help is appreciated.
