The number not the size of arriving packets is usually the limiting
factor. For further investigations, I would suggest to use "vmstat" to
monitor the maschine. Have an eye on the number of interrupts and
context switches.

Good luck

Hi,
i am trying to get Netramet up and running and are running into some
problems, i tried to install Libpcap on Unix Solaris and only went so far
but the Libpcap.a file was created, i then went ahead as stated in the
manual, and reference guide, and it seems to have worked, but i am not fully
sure, is Libpcap.a, all that is needed ???
I know i can not really be sure is it working until i get a meter
running, but is there any way just to check is it probably installed
Also i am trying to install a meter on a machine, but have i never
heard of Borland power pack for Dos, what is it and is it deffinetly needed,
i have made enquires at have come up a blank,
i am using Netramet to try and gain some hands on experience with
low level traffic flows and Network operation, any help would be greatly
appreciated

These days you probably don't want to build the DOS meter.
Borland Power Pack has been unavailable for several years now,
it was a 32-bit memory package for the DOS environment.

If you want to build NeTraMet from the distribution file,
the simplest environment is either Linux ot FreeBSD. Provided
you have libpcap installed (you may nateed to specify that as
part of building your kernel, though I think Linux has it by
default), you should be able to just ./configure and make.
For this I recommend you use the latest beta version,
ftp://ftp.auckland.ac.nz/pub/iawg/NeTraMet/beta-versions/NeTraMet44b8.tar.gz

ANother possibility is to try the Windows version. The (binary)
files for that are in the beta-versions directory as
MSW_NTM44b6.zip

I found that building it for NetBSD was also very easy. I think I even have
a netramet package at netbsd.org in the packages collection.

Hello,

Before writing my first message, let's introduce myself: I am a french
student living in England and I am 22. I am using NeTraMet to collect the
DSCodePoint of each packet.
So my question is does anybody know the object ID of the DSCodePoint in the
RTFM MIB? In fact, I am trying to collect it from the MIB with another tool
so I would need his OID.

Thanks a lot,
brice

We are working with NeTraMet v4.3.
The DSCP's OID is:
1.3.6.1.2.1.40.2.1.1.118.flowruleset.0.flowindex

The key was determining we also have to add the last three items.
You have to build the OID of any attribute on that pattern.
For you the most difficult part may be to get flowruleset
and flowindex attibutes.

The easiest way I have found is to retrieve them from the flow
data file once the rule set is downloaded (see the format line).
At that time in the flow data file, the 'flowruleset' will remain
the same value (usually first column), but 'flowindex' changes
depending on how many flows NeTraMet has captured (usually second
column in flow data file).
This means, you cannot just get a dscp value, you have to specify
what flow you are interested in and the ruleset.

Another way will be to ask NeMaC to dump these values somewhere in
a file. Doing so would require changes to the NeMaC source code,
which I wouldn't recommend very much for this purpose.
Hope this will help.
