I have SSH to a server, two open ports for bit torrent connections and
a few ranges for DCC transfers from irc.

The possibility of a DoS attack is pretty real, I imagine.  Is there
any way I could be sure?

[gentoo-user] Gentoo router: Conntrack table full

[Dan Cowsill]

Hi folks,

Today I had some really serious problems with my Gentoo router.  I
could ping it, and all the network connections were in place and
functional, but no outside access.  I looked into it and found that
the syslog was flooded with this:


Mar 22 21:25:55 localhost kernel: nf_conntrack: table full, dropping packet.
Mar 22 21:26:00 localhost kernel: printk: 11 messages suppressed.
Mar 22 21:26:00 localhost kernel: nf_conntrack: table full, dropping packet.
Mar 22 21:26:05 localhost kernel: printk: 16 messages suppressed.


These messages spanned a full 20 hours of the log.  I understand that
conntrack is the connection tracking system that iptables uses.  I
also understand that its maximum is something on the order of 65000
simultaneous connections.  For a simple home network, I think we can
agree that I would probably never approach this number of connections
with normal use.

So my question is this:  what could have caused the router's
connection tracker to overflow?

How on earth do you justify that statement? I am an AMD fan and have

tell you that the performance of the Intel Q6600 makes the AMD Phenom 
7600 look decidedly  pathetic and the Intel is cheaper - at least where 
I shop. I have both so I am talking from practical experience. I have an 
AMD Phenom 7500 sitting on the floor behind me which isn't even worth 
sticking in a motherboard. Another Intel Q6600 arrives on Tuesday. I 
really hope AMD get their lead back but they are struggling at the

[gentoo-user] nVidia GeForce4 MX 440 AGP 8x - tainted driver 96.43.05 causes X crash sig 11 - Kernel 2.6.24-gentoo-r3

[Gregory Shearman]

Last week I upgraded the kernel on one of my 5 year old Pentium 4 desktop
machines to 2.6.24-gentoo-r3. Kernel compilation went fine as usual but
when I tried to emerge the current (x86) binary nVidia driver [96.43.01]
for its GeForce4 MX 440 AGP 8x graphics card it failed with an error
message that the it couldn't determine the kernel version.

The graphics card is around 5-7 years old and won't run on later 1xx.xx.xx
versions of the binary blob, so I'd masked the driver to:

/etc/portage/package.mask/nvidia-drivers

>=x11-drivers/nvidia-drivers-97.00.00

==

The driver worked fine on the previous kernel 2.6.23-gentoo-r9. The solution
was to do what I've always done for binary blobs (nvidia,ati,madwifi-ng
etc) and add:

/etc/portage/package.keywords

x11-drivers/nvidia-drivers ~86

==

This allowed me to go from 96.43.01 to 96.43.05.

Unfortunately, even though the driver compiled fine and started without
error this driver proved to be unstable on my machine and graphics
hardware. X (1.3.0-r5) failed on KDE logout with:

/etc/var/log/Xorg.0.log:

Backtrace:
0: /usr/bin/X(xf86SigHandler+0x85) [0x80c7c57]
1: /usr/lib/xorg/modules/drivers//nvidia_drv.so(_nv001216X+0xe5)
[0xb71d6711]
2: [0x1]

Fatal server error:
Caught signal 11.  Server aborting

===

Maybe running the uvesafb framebuffer and fbcondecor (livecd-2007.0 theme)
has something to do with the sigsegv problems on just this particular
driver version but I knew that I couldn't run this driver.

I did a bit of research and found an ugly hack to get the 96.43.01 driver
working on kernel 2.6.24-gentoo-r3 so I changed the mask to:

/etc/portage/package.mask/nvidia-drivers

>x11-drivers/nvidia-drivers-96.43.01

=

I then worked the dark magic:

# ln -s  /usr/src/linux/include/asm-x86 /usr/src/linux/include/asm-i386

(/usr/src/linux points to the new kernel 2.6.24-gentoo-r3)

==

I reemerged nvidia-drivers and the hack worked. I got the reliable 96.43.01
driver working again, though with some concerns about future reliability.
There might be other changes within the kernel 2.6.24 that driver 96.43.01
doesn't know about that could cause me some grief in the future, but for
now it works fine. 

Now a week later I find that portage has released the nvidia binary driver
96.43.05 as stable on x86. I allowed it to emerge, but it still had the X
killing problem when logging out of KDE.

Some of the things I've read suggest nvidia have been informed of this
specific problem but I was wondering if there's any more information around
about this issue? I know the card is getting old and perhaps I should use
the open nv driver, but the card usually works really well with the binary
blob.

I would also like to know if these problems were known to the Gentoo devs
when they released 96.43.05 as stable on x86.

 As strange as this may sound, we had a server go down and we thought
 psu/mb. it turned out to be the cmos battery. We replaced it (about four
 years ago), the server has been flawless since.



Different motherboards must exhibit different behavior with a bad CMOS
battery.  Another desktop of mine prints an error to the POST screen
about its bad battery.  There is a comment here from another owner of
my MSI motherboard:

http://www.ebuyer.com/product/127597/show_product_reviews

"This is a great board too, except i got an error each boot-turns out
the battery was dead, swapped it and it was ok"

It sounds like my motherboard should still boot with a bad battery.

I had one with a dead battery too.  It lost all the settings and the 
clock reset back to 1971 or something like that but otherwise it worked 
just fine.  Well, after getting it to see the drives again. 


Weird things happen I guess.

Hi.

AMD has had better engineers than Intel all the time. Intel just had the money.
A few years ago the CIO from Intel advised engineers to be more creative. So AMD
will stay ahead of the pack and if they find the right way (actually they're
going the right way -> open specifications) the competition is going on.
I hope that nVidia won't acquire AMD.
In fact atm. there is no measurable performance difference weather in IU nor in
FPU operations, however AMD has a better performance/price.
In HPCs AMD beats Intel because they don't use obsolete FSB. I am looking
forward to the new CPU architecture where GPU and CPU find together.

I am using Intel technology because chipset, wlan, bluetooth and so on are
working great together, although there is no HypterTransport. Intel is going to
follow AMD because they have the money.

acm.

As far as I know, and unless something changed, that's inaccurate.

They haven't released any code at all. They have released *some*
specifications for some graphics chips.

They started releasing the register specs for some cards. Recently,
they released the 3d specs, only for r500 chips as far as I know.
It's better than nothing of course... But it far far far from open
sourcing the drivers or releasing the whole specifications for every

I would be glad to be wrong though. I must admit that I don't follow
too closely the thing, so, any info to probe me wrong is more than
welcome.

Feel free to file a bug on kernel.org. They'll either fix it or eventually

As strange as this may sound, we had a server go down and we thought 
psu/mb. it turned out to be the cmos battery. We replaced it (about four 
years ago), the server has been flawless since.

When/if AMD is able to complete their new architecture, integrating
video processors with 64 bit processors they might become competitive
on a cost/performance basis. Certainly with AMD open sourcing new video
driver development, they still have a v very strong appeal to open sources
users. HIGH end technical clusters and the processors they use are different
needs than the average small business or consumer, which needs robust support
for open source video and applications.


If everyone runs to Intel, we'll all be *very sorry* in a few years...


The ultimate questions is do you really make a purchase decision base strictly
on extreme benchmark results, or do you stand by your vendor, as they regroup
and keep things competitive? Remember Intel has been just as evil as Redmond
particular in matters related to DeCSS and video on computer issues, IMHO.


AMD is my soul_mate(particularly since they are open sourcing new
ATI video drivers...)

price/performance still favours AMD.

Also, without even knowing your hardware, it is really hard to say why your

I work at the German Aerospace Center (basically the German NASA). We've
been using AMD CPUs for a long time on our clusters and workstations
because they were not only cheaper but also faster on floating point
operations whereas Intel was faster on integer operations. Now we are
switching to Intel because AMD lost this advantage and has problems
delivering the ordered number of CPUs.
I personally stick with AMD because they have a factory in Germany and I
don't want Intel to rule the market as they've done before AMD came up
with the Athlon XP.
  
I can confirm that. The German Weather Service uses AMD CPU's on the 
servers for visualising weathercharts due to better FPU performance.

The new bunch of servers however are intel systems.

Well the experience of a desktop or an application depends on more than

then you have the software, what software you use, how it is build, what

I thought Dale said that he hadn't anything set to compile as a module.


He doesn't seem to specifically state that.
He does (subsequently?) say that he doesn't _want_ anything as a

As I read Dale's original post, all he says is "I set 
CONFIG_SCSI_WAIT_SCAN as `not set`" (and in his post of 21 March 2008 
16:13:49 GMT he says "if I say `compile it in'") "and it keeps turning

Of course this would prolly be much easier if Dale just posted a copy 
of his .config. I have a feeling something "obvious" is being 
overlooked, and it wouldn't do any hard to post the output of `cd 
/usr/src/linux && ls -ld /usr/src/linux && md5sum .config && make && 
make modules_install` so we can see stuff for ourselves. You'll notice 
that  I look to check things like the /usr/src/linux symlink here and 
that the .config used is actually the same one as I suggest he posts.


Stroller.


True, you may have to read between the lines but I do not have any 
modules with the exception of nvidia.  I have to have my picture on the 
screen so I can surf the www.  LOL 

I attached a copy of my config for you to look at.  I have not changed 
the symlink yet because I have not actually booted the new kernel yet.  
This is what I get after trying to make a kernel:


[EMAIL PROTECTED] /usr/src/linux-2.6.24-gentoo-r3 # make all && make 
modules_install

 CHK include/linux/version.h
 CHK include/linux/utsrelease.h
 CALLscripts/checksyscalls.sh
 CHK include/linux/compile.h
Kernel: arch/x86/boot/bzImage is ready  (#3)

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

make: *** [modules_install] Error 1
[EMAIL PROTECTED] /usr/src/linux-2.6.24-gentoo-r3 #


I suspect that I can leave off the make modules_install since there 
*should* not be any.  It also says it makes the kernel itself.  I'm just 
curious if my nvidia drivers will load without the loadable modules 
option there??


My wish list, the ability to compile in loadable module support into the 
kernel and whatever else it has to have with it.  Back to nothing being 
a module except nvidia.


If I can't have it that way, I guess I'll have a extra module.  Of 
course, then something else will likely creep in the list too.   ;-)


I hope the extra info helps.  Thanks.

Oh, that interests me: Which VM enables you to actually burn CDs? I
tried Qemu once and were told at that time that there is no VM with
CD-burning functionality.

Did you actually burn it from within the VM, e.g. having that much
control over your hardware or did you create an image you later burned
with native linux tools?

[gentoo-user] some OSS software that enable me make call to traditional telephone by using Internet?

[Zhang Weiwu]

Dear all

I wish to be able to make telephone call from Internet to Traditional
telephone, like I did with skyp out. But I am using Linux on ppc, and
skype did not release ppc binary.

Is there a solution for people like me? I think if there are OSS
solutions they are preferable because then it tends to be able to
compile on any kind of hardware. Actually any solution (including
binary-release software) are fine for me, as long as they can run on
Linux/ppc.
