Darkstat worked like a charm on my laptop yesterday, for traffic to/from the laptop. So this morning I've been trying to make it work in the serverroom. I've set up a monitoring port on the switch and mirrored a vlan to it. To this monitoring switch port, I've connected the second nic on a spare server. But I can't make it see the traffic: *Running for* 38 secs*, since* 2012-08-30 08:27:12 UTC+0000*.* *Total* 0 *bytes, in* 0 *packets.* (2,512,454 *captured,* 2,494,741 * dropped) *And so the graphs are blank :-( I've tried several incantations to no avail: usr/local/sbin/darkstat -i eth1 -p 5001 --no-daemon --no-dns -l " 0.0.0.0/0.0.0.0" --local-only /usr/local/sbin/darkstat -i eth1 -p 5001 --no-daemon --no-dns -l " 0.0.0.0/0.0.0.0" /usr/local/sbin/darkstat -i eth1 -p 5001 --no-daemon --no-dns I've even tried assigning a bogus ip address on the monitored subnet to eth1, but that doesn't help either. Any suggestions? with kind regards, Bent
