Hi,
Does connection tracking keep any counters on number of packets/and
or bytes that are
associated with a connection? If so how does one access them?
echo 1> /proc/sys/net/netfilter/nf_conntrack_acct
Then, you can access them via:
conntrack -L
Hi Pablo,
I have been working with FreeBSD for about 10 years and using ipfilter.
It has a neat tool ipfstat -t which show the state table
sort of like top. It is very useful if someone is hogging the network
because it is sorted by the highest user first. We are switching
our systems to Linux and would like to know fs there anything like this
for conntrack?
Src: 0.0.0.0, Dest: 0.0.0.0, Proto: any, Sorted by: # bytes
