ons are accessed, so the underlying whole device must be less
that 1TB as well. Fixing this requires updating the kernel all the way from
the device drivers to the highest levels in the kernel, and even some system
applications.

sense to have both. It's not clear if there is a default
or what it defaults to or when such a default is relevant. There needs to
be a "half-duplex" option to make this explicitly clear in the configuration.

r type of attack - lots of connection
requests/new connections use up all of the mbuf clusters and they have to
time out before the network is usable again.

I should have spoken up earlier, but none of these reports has
indicated a problem. The "92%" above is the percent of buffers that have been
allocated and are currently in-use. The system allocates more when the pool
runs out. The % in use is essentially a useless number that shouldn't e
ize of mb_map. Bumping up MAXUSERS in reasonable amounts
> will, in fact, contribute to a larger mb_map.
Only if you don't specify NMBCLUSTERS, which the original poster did.

increase it to 10X what
you have now, but keep in mind that each one consumes 2KB of RAM, so you
could end up using a lot of memory for buffers after the attack occurs.
