Dear misc@, I am using the 4.4-current CVS from 2008-09-17, and having problem with exporting NetFlow data with the new pflow pseudo-device. The setup used to work just fine using softflowd. There is nfcapd at the receiving end, but this probably is irrelevant.
$ netstat -s -f pflow pflow: 25053 flows sent 835 packets sent 0 send failed due to mbuf memory error 834 send error It seems that only the first send succeeds as I can see data around the time I booted to the latest compile of kernel & userland. With pfctl I can see the states correctly marked as (pflow, no-sync), using the set state-default pflow, no-sync. But for some reason the sending fails (after 1 successful send?). tcpdump reveals no packets actually being sent out. PF is set to pass all. $ ifconfig pflow0 pflow0: flags=41 mtu 1464 pflow: sender: 10.0.16.1 receiver: 10.0.16.20:9996 groups: pflow 10.0.16.1 is on a vlan interface if that makes any difference. Any ideas? What could I do to dig deeper into the problem or help track down possible bug? Is it still so much "work in progress" problems are expected?
