Hello Adolf,
If the Prime appliance is not suitable for testing any more, I am sure we can
find you something else.
It can still be used for testing and even for some bug development. It is just
that with the IPS enabled, that uses 1.4GB on its own so the memory usage is
around 88% to 94%.
I have noticed that Suricata has become very memory hungry recently, too. I
think it is since we upgraded to version 7, but I did not verify this.
So doing something like a change to the IPS rulesets that are enabled ends up
going into something like 20% swap usage and trying to access the Prime via SSH
has ended up at 35% swap usage just now when I tested it.
The impact of the swap usage is just that everything ends up going very slow.
This appliance is already very slow and the disk-on-module is not super fast
either. This is not fun to use.
Disabling the IPS resolves the swap usage because the memory level is then down
at 50% or less.
What would you need?
I don't really know. I find it good to be able to do testing on both vm and
physical hardware and the definite benefit of the Prime is that it has a wifi
connection so I can test out the hostapd element of IPFire, which I can't on
the vm systems.
I have thought on and off about replacing my "production" old mini appliance
with one of the new mini appliances and then I could use the old mini appliance for
testing etc although it doesn't have a wifi connection.
We can fix that. I am sure I have a spare WiFi module somewhere around. Are you
using WiFi in your production appliance?
I am using a couple of WAP's around the house for my wireless connection so no
wifi module in the unit itself.
Regards,
Adolf.
Until I get to a point to getting the new mini appliance the Prime definitely
is of benefit to my testing.
Maybe I use the vm systems for IPS e\valuations and disable it on the Prime.
That would probably help with the memory and performance.
That's a good idea. I will give that a test out and see how things go.
Best,

Adolf,
If you have access to a 4GB DDR3 SODIMM (even if you temporarily grab one from
an old laptop or borrow from a colleague), you could try installing it. I
wouldn't be surprised if the system booted up and either supported the full 4GB
or limited it to 2.44GB, but worked nonetheless. It won't hurt anything to
try. Worst case, the system does not power up until you replace the original
SODIMM.
Thanks for the suggestions Tim. Unfortunately didn't help. My oldest laptop
turns out to have DDR2 and the SODIMM's are 2GB anyway.
My newest laptop has DDR4, so not usable.
My netbook does have DDR3 but with only a 2GB SODIMM.

Hello Adolf,
Hmm, this might be difficult. I remember that this processor was a little bit
limited in how much RAM it supports.
However, the Intel Ark says max. 2.44 GiB
(https://www.intel.com/content/www/us/en/products/sku/58916/intel-atom-processor-n2600-1m-cache-1-6-ghz/specifications.html).
I am not sure how to put this in, but generally that seems to be not much
higher than two.
I think you are right.
I am only using it as a Testing evaluation system and as a system to do bug
development work on.
So I think I will just have to accept that the memory might be used up a lot
and periodically it might go into swap use. I can live with that.
Regards,
Adolf.

Hi Arne and everyone,
In the monthly conf call I forgot to ask this question.
I have an old IPFire Prime system which has a 2GB sodimm memory card installed.
The memory is very close to fully utilised so that periodically the swap space
gets used for memory.
I would like to buy some larger memory for it but I need to know if I can use
8GB cards with it or if it is limited to 4GB as the largest memory size that is
usable (or worst case, that I have to stay with the 2GB card if that is the
biggest supported).
Anyone know what the max ram memory that can be supported by the Prime systems
is?
Regards,
Adolf.
