IP6tables crash

Hi all.

While using SuSE 10.0 (kernel 2.6.13-15.8 default) the computer
sometimes crashes to a black screen.

There is a warning saying
"Starting firewall initialization (Phase 2 of 2) SuSEfirewall2:
Warning: ip6tables does not support state matching. Extended IPv6
support disabled"
"Master Resource Control: runlevel 5 has been: reached"
"Skipped services in runlevel 5: irq_balancer nfs smbfs xend"

Then it goes to "linux login", but no input can be given in any way.

I admit it could be my fault... I tried to configure a samba server for
my home lan, but i thing i have messed with something.

Can anyone help?

Many thanks

The ip6 message means what it says. IP6 does not support state matching,
ie, if http do something. Not sure about the irq_balancer "google" finds
this appropriate for multi-cpu systems, ie, trying to balance irqs
between 2 or more processors.

Have you installed a multi-processor OS on a single processor system or
vice versus? Otherwise memory error?

Sorry pal I forgot to say I am totally new to Linux and to serious (non
Microsoft) computing .

So, what is ip6? And "State Matching"?
I have installed SuSE 10 on a AMD 64 Sempron, no multiple processor or
so.
But the service is skipped when loading: could it be that SuSE enables
it only if it finds a multiprocessor?

It seems the problem has been "fixed" by turning the firewall off, but
I am not sure.

Sorry I was away. IP6 is an new version of internet protocol address
scheme using 6 number sets instead of the 4 that are used in IP4. IP6 is
supposed to do 2 things, uniquely identify a host and increase the number
of network addresses available. I forget why iptables doesn't
do IP6 state matching.

IP4 normally uses numbering like 192.168.0.1 to identify a host machine on
a network. For IP4 usually the first 3 sets indicate the network and the
last indicate a host. There are complete descriptions on the internet
but that is the basic.

To communicate on the internet from say google to your pc. Your pc first
sends a little hello packet onto the internet looking for google. Machines
(routers, etc) pass that packet along until it gets to google which sends
back an acknowlegement packet which is also passed along until it gets
back to your PC. Then your PC starts sending packets to google with a port
number to telling the google machine what kind of connection you're
establishing. Google sends back a port number confirming the connection
and your pc has it's established connection.

The status of that port connection is its state, ie, new, established,
related. A new packet on that port, an established connection, a related
connection.

In the first place that's IPv6 not IP6.

In the second place it has been around for many years so can hardly
be considered "new".

However- yes- the basic purpose is to increase the name space since the
world is pretty much out of name space for the existing IPv4. At one
point 2^32 addresses ( 4 billion ) seemed like a lot but not anymore!
