I noticed that my pflow device keeps rebooting with Netflow version 5, despite "pflowproto 10" being set in /etc/hostname.pflow0. I'm running OpenBSD 6.5 with the latest patches.
ifconfig: pflow0: flags=41<UP,RUNNING> mtu 1448 index 9 priority 0 llprio 3 pflow: sender: [<IPv6 address>] receiver: [<IPv6 address>]:2055 version: 5 groups: pflow /etc/hostname.pflow0: up flowdst [<IPv6 address>]:2055 flowsrc [<IPv6 address>] pflowproto 10 After boot, if I manually initiate "sh /etc/netstart pflow0", it then starts using version Netflow v10 as expected. I may be able to add to /etc/rc.local to do this on reboot, but thought I'd see if there was anything else that it could be. Thanks, Andrew
