Hello,
I'd like to check the 'conntrack' tool. However, I can not compile it.
(Actually, I cannot compile libnetfilter_conntrack-0.0.20)
There is neither "linux_list.h" nor
"libnetfilter_conntrack/libnetfilter_conntrack_extensions.h" header files.
I know, where to find the first of them, but what about the second?
Could you give me some hints?
P.O.

You need Linux Kernel 2.6.14 and need to specifiy the kernel directory
while compiling.

Of course, I did it.
Actually, I've compiled 2.6.14 but still running 2.6.13.
So, for configuration of I run:
./configure --with-kernel=/usr/src/linux-2.6.14
But it didn't help.
P.O.
ps. The mentioned file
(libnetfilter_conntrack/libnetfilter_conntrack_extensions.h) is not present in
any of sources of: libnetfilter_conntrack-0.0.20, libnfnetlink-0.0.11,
conntrack-0.90, iptables-1.3.[34].
Moreover, linux_list.h is in sources of iptables-1.3.4, but installation will
not copy it in any include/ directiory. So, one has to do it himself.

Hmh,

They worked for me.

Positive! The SVN version works. (I hope they will change default download to
a right version soon.)
Thanks for the suggestion.
So, I will be back with questions how to use it :)

I may be asking in the wrong area, but hopefully someone can point me in the
right direction.
Does anyone have an idea as to anything I could use to put the IPTable
connection attempts into a SQL table of some nature for another developer to
build off of. I'm only somewhat experienced with linux and very
inexperienced with IPTables, so I'm beating my head against the same walls.
Essentially, what we're doing is this -- using a *nix box to as a
provisioning server that updates firmware and configuration on customer's
VoIP ATAs via TFTP (port 69). The only catch is that we need to know which
customers have been updated. This can be done by comparing MAC addresses (of
the box logging in), but first I need to get the data into a table of some
nature or even just a regular file. I've looked at the log and seeing as how
it logs each packet, it's far too large to be of any use to me.
Any ideas? Just point me in a direction perhaps? Maybe an add-in of some
nature? I'd prefer to NOT do this with windows... Just because I'm not sure
if a Win box could handle everything properly.
Thanks for your time,
Daniel

iftop does something like this, not looking at the conntrack table but it
may help.

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?

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?

I mean, if an outsider talks to x.y.z.1 and the load balancer forwards
that packet to x.y.z.2, so the outsider will get a reply from x.y.z.2

Hi all,
i used to use iptables conntrack module. as our servers are really
busy and get a lot of connections, we got a lot of errors like
conntrack: table full, dropping packet. due to resource limits
we dont want to increase the conntrack_max limit, its currently
set to something about 32000.
how can we configure iptables so that some ports are excluded
from being tracked? as most connections are incomming on only
around 5 different ports all problems should be solved with
such an option :)
is there anything like iptables --notrack -dport 80 ..?
would be great!!
thanks for any help,
corin
