tion_guide_chapter09186a008007ebf9.html as well as "port monitor"
command.
This way you should be able to configure a single port on (at least the
2950) switch that would mirror all the traffic.....

That will do.
Sorry if I dind't take the time to look in deeper.  I know this works.

Thanks for the information I have not done anything as of yet as I do not
know the best approach to take.  My boss just put's it down to Large Emails
and our T/S application's always printing.

I would like an IDS but we do not have anything as of yet, we have 3com 4250
switches and 2950 (I think!) GIG switches do you know how I could configure
a single port on each that would mirror all the traffic.....

Our main SQL database is a custom app written by 3rd party but we have over
150 T/S sessions using it

I personally would use MRTG.

You can find that package at www.mrtg.org

Have you started doing any type of Foreinsic on your network?

Do you have any type of IDS on my network?

With you SQL database server have you looked to see what
application(s) are doing huge amount of calls.

Yours

Dear All,

IF possible I am looking for some advice on some problems our users, over
the last 2 weeks our network activity has increased 10 fold, most of our
applications are running very slow, from email, SQL databases and our
application in particular the ones that use Tarantella Secure Desktop a

RDP

based Terminal Services.  WE have recently moved the T/S to another

location

with a 2MB WAN link and I am really looking for some advice and types of
tools I could use to monitor the traffic from site A to B and the internal
LAN of site A and B.

We use all 3com Managed Switches and the link is provided by a managed
service, I thought about running Ethereal but understand as we uses

switches

I would have to mirror a port on each of the 5 switches, is there a tool I
could install on either site to monitor the traffic, my main concern is
either with have an increase in RDP traffic or perhaps a potential

problem.

Kind Regards
