ping question

[ann kok]

Hi Loren

Thank you for your mail again

For the monitor sofeware iptraf , I can't get it in
the port. Why freebsd doesn't support it!
I tried to install in freebsd from the tarball and got
an error messages!

I need sth to prove the traffic to those routers from
outside. 

Do you have experience the max traffic freebsd can
support? It seems to support max 230M only!

Thank you
