I have run into a need to capture netflows from the internal interface
of my FreeBSD 6 server. The internal interface is em0 and the
external interface is em1.
I am using the following to setup the netflows.
/usr/sbin/ngctl -f- << SEQ
mkpeer em0: netflow lower iface0
name: em0: lower netflow
connect em0: netflow: upper out0
mkpeer netflow: ksocket export inet/dgram/udp
msg netflow:export connect inet/22.214.171.124:12345
When I run the commands above, I receive the following message.
ngctl: send msg: No such file or directory
ngctl: line 1: error in file
I am at a complete loss here. My understanding of netgraph is poor at
best. Any suggestions would be appreciated.
