Also, as to my original question, I am still wondering whether I should bump
these numbers up or down in order to increase the amount of traffice (or
numbers of running dumpers) that amanda will allow.
netusage 4000 Kbps # maximum net bandwidth for Amanda, in KB per sec
define interface le0 {
comment "100 Mbps ethernet"
use 4000 kbps
I'm pretty sure I RAISE the netusage variable, but what do I do to the
interface 'use' attribute?

Brandon
err you mention the le0 interface in the config.
Is this correct 'cos the the le0 interface is a 10base system, not
100base!..
