We have a small network connected to the Internet via fractional T1.
We'd like to start collecting information about our bandwidth usage, but
our ISP will only provide us with those statistics for a fee.
Here's a sketch of our layout:
(internet)

|
CSU/DSU
|
|
Cisco router
|
|
----------Public, unprotected net--------
| |
| Four different machines |
| (all Linux boxen) |
---Linux firewall------------------------
|
|
(internal net)
Are there tools for doing this sort of thing? Some sort of perversion
on tcpdump maybe?
====================
Have you tried using snmp from Linux to the Cisco router? You'll have
to do some script development, but that's the fun of linux, neh?
