Mbuf errors
Hi All,
Mysql service is going down continously in my system due to lack of memory
space.
I checked the messages log and found the following error message.
All mbuf clusters exhausted, please see tuning(7).
I have no idea about mbuf cluster. Can anyone please help me to fix the issue.
I hope the information below will help you.

status of autotuning freebsd for 9.2
Andre,
Are you going to have time to MFC things from -current for auto-tuning
-stable before 9.2?
I fear (maybe unnecessarily?) that we are about to ship yet another
release that can't do basic 10gigE when sufficient memory exists.
If you don't have time, then let me know and I'll see what I can do.

load testing and tuning a 4GB RAM server
Hello everyone,
First of all, great job on the 4.8-R. We have been a long standing user of
FreeBSD and are very happy with everything.
Now my question. I am trying to stress test a new Dell PowerEdge server
and find the limits of its hardware and my tuning. Here are the server
stats:
* 2x Xeon 2.8 with SMP compiled, hyperthreading NOT compiled in kernel
* 4 GB of RAM, 8 GB of swap on Raid 1

lots of sockets in TIME_WAIT
Hi there,
I have some DDOS(?) attack on my router going where my apache HTTP
server is flooded with short-timed connections from some host. This
results in LOTS of sockets in TIME_WAIT/LAST_ACK/CLOSING states and
eventually I'm out of mbufs, which, consequently means I can't even
connect to the router from LAN. The kern.ipc.nmbclusters is 2560, (I
guess high enough for router with

VS: 4.8-STABLE Kernel Panic with dummynet options.
I first saw this problem when our internetgateway refused to boot its new
kernel, it was a 4.7-RELEASE. Then i loaded the old kernel and went home to
check if my 4.8-STABLE does likewise. And the answer was yes! Both kernels
were GENERIC + these options taken from the dummynet man pages:
options DUMMYNET
options NMBCLUSTERS
options HZ

Mbuf Clusters on 4.8
Ive been googling quite a bit now for problems with
running out of mbuf
clusters. Im basically sending a 30k datachunk down
1000-4000 connections,
but 1000 is more than enough to quickly fill upp 8192
mbuf clusters. I also
tried setting maximum amount of mbuf clusters to 65536,
but that only made
the box hard-wire 86MB of 96MB RAM, making it just as
unsuable as a dead
machine.

[Fwd: CERT Advisory CA-2003-13 Multiple Vulnerabilities in Snort Preprocessors]
I figured that someone reading this list might want to take a look at
the proceeding, considering that the version of Snort in FreeBSD ports

ixgbe/ix sysctl missing in FreeBSD 9.2
Hello everyone,
I am trying to tweak some of the sysctl tunables for the ix (ixgbe) driver
in FreeBSD 9.2 since I am experiencing less than ideal performance and it
seems like I can't find any:
# sysctl -a | grep -i ixgbe
device ixgbe
I am running 9.2-RC4.
Any input appreciated.
Thanks,

HEADS UP: OpenSSH 3.8p1
Take the usual precautions when upgrading.
Also note that I have changed some configuration defaults: the server
no longer accepts protocol version 1 nor password authentication by
default. If your ssh client does not support ssh protocol version 2
or keyboard-interactive authentication, the recommended measures are:
1) get a better client
2) get a better client (I mean it)
3) get a better

still mbuf leak in 9.0 / 9.1?
Hi list,
since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the
system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands.
A clean shutdown isn't possible

4.8-Stable DummyNet
Hi. We just opened a gaming center and have chosen to run a FreeBsd box for
our firewall. IPFW is configured at it's very basic running natd through rl0
and allowing any to any connections from the lan to the outer world. Natd
controls access to the lan.
We have a 6.0 mb/s ADSL net connection for all the gaming clients to use,

Equal bandwidth configuration among host with dummynet
Hi all,
First of all, I have spent a lot of time reading up on
it.
Anyway, I live in a shared accomodation with 2
roommates and a landlord and we share a cable internet
connection. It is 2Mbit/400Kbit connection. Sometimes
when one of us is downloading a song through Kazaa or
a new Linux or FreeBSD iso, the bandwidth gets hogged
and other users can't get through.

SYN Attacks - how i cant stop it
Hi,

What else can i do to get optimum protection.
Thanks.
