Hi, Rebecca, this is Debian's users list, not GIMP developers bug
tracker. Maybe you should check what are the best ways to inform of a
problem and ask for some help -always in a gentle and respectful
manner, because this is just a voluntary community effort.
Anyway, you're not giving any relevant information, e.g., Debian
version in use, symptoms of that crashing, the output of a terminal '$
gimp', etc.
Probably with more (some) info about your issue someone will aport an
idea to solve it.
Best regards.

1. Restore your operating system backup, or do a fresh install of Debian,
   perhaps in a virtual machine.
2. Repeat the steps that caused the problem, using 'script' to
capture all the commands and their output.
3. Post the 'script' capture here, or in a pastebin if it is too big for email.
4. Restore your operating system backup, or do a fresh install of Debian.
5. Restore your data backup.

Perhaps a different brand adapter card would give better results.

Maybe; I will get some prices for comparision... In terms of the base

Buying a new major brand server/ workstation with all the parts

As other readers have mentioned, a small business that builds to order

In addition to U.2 drives, Intel makes server systems:

libffi also has a habit of using /dev/shm for writing temporary

For the new server, I will need more storage, so I envied getting two

the opportunity to upgrade performance and that they are not actually that

Of course, given the fact that server manufacturers have entirely different

need to change plans a little...

Yes. It is close to the same here with the additional SSD usage for VMs  
and containers.


Understand that a 4 core 5 GHz CPU and a 16 core 2.5 GHz CPU have similar  
prices and power consumption, but the former will run sequential tasks twice  
as fast and the latter will run concurrent tasks twice as fast.


Is this still true today? AFAIK all modern CPUs "boost" their frequency if  
they are lightly loaded. Also, the larger CPUs tend to come with more cache  
which may speed up single-core applications, too.


Yes, frequency scaling blurs the line.  But, the principle remains.


I am not familiar with AMD products, but Intel does offer Xeon processors  
with fewer cores and higher frequencies specifically for workstations:


https://www.intel.com/content/www/us/en/products/docs/processors/xeon/ultimate-

AMD does it too, but their variants are more targeted at saving license  
costs by reducing the number of cores. As I am mostly using free software, I  
can stick to the regular CPUs.


If I go for a workstation, I will end up with Intel anyways, because Dell,  
HP and Fujitsu seem to agree that Intels are the only true workstation CPUs.  

I would think that you should convert one of your existing machines into a  
file server.  Splitting 4 TB across 2 @ 2 TB HDD's and 2 @ 4 TB SSD's can  
work, but 4 @ 4 TB SSD's with a 10 Gbps Ethernet connection should be  
impressive.  If you choose ZFS, it will need memory.  The rule of thumb is 5  
GB of memory per 1 TB of storage.  So, pick a machine that has at least 20  
GB of memory.


4x4T is surely nice and future-proof but currently above budget :)


Yes, $2,000+ for 4 @ 4 TB SATA III SSD's is a lot of money.  But, U.2  
PCIe/NVMe 4X drives are even more money.


Noted. Actually, 4x4T SATA is affordable, as is 2x4T U.2 if not bought from  
the server vendor [prices from HPE are still pending, but I am scared  
by browsing for them on the Internet already...] :)


[...]

down to their speed -- the current "fastest" system here has a Xeon E3-1231  
v3 and while it has 3.4GHz it is surely slower (even singlethreaded) than  
current 16-core server CPUs...


That would make a good file server; even better with 10 Gbps networking.


10GE is in place already, but there are other hardware limitations (see  
next).



Thinking of it, a possible distribution accross multiple machines may be

* (Existent) Storage server (1U, existent Fujitsu RX 1330 M1)

3 TB HDD's -- ~$50 each on eBay.  Buy four drives for $200, buy small 
SATA III SSD cache and log devices for $100, and you will have 75% the 
capacity and excellent performance for typical file server workloads for 
$300.



I saw 
that the Supermicro AS-2113S-WTRT can do 6xU.2 drives. In case I chose 
Supermicro this would allow upgrading to such a 4x4T configuration.


As for the workstation, it is difficult to find a vendor that supports 
Debian.  But, there are vendors that support Ubuntu; which is based 
upon Debian.  So, you can run Ubuntu and you might be able to run Debian:

Depending upon what your VM's are doing, a SATA III SSD might be enough

I think from systemd:

and I think if you wish to alter the mount options you should put it
in /etc/fstab and then systemd will do the equivalent of:

# mount -oremount /dev/shm

to get your options set, though there would be a small window where
it had the default options.

Though note that it seems systemd once did use "noexec" for /dev/shm
but stopped 10 years ago because it broke some uses of mmap:


https://github.com/systemd/systemd/commit/501c875bffaef3263ad42c32485c7fde41027175

On SysV init systems I think this is part of the initscripts

There are a few other directories where users can typically write to

It's mounted by systemd, the list of core systems it mounts is hardcoded
in the source[1].  Filesystems that appear in /etc/fstab are remounted
with the options given there (for the gory details see
systemd-fstab-generator(8) and systemd.mount(5)).

Mounting /dev/shm noexec

2020-10-02 Thread Valter Jaakkola 
Hi,

I an effort to increase security one of the things I'm trying to do is to have
no world-writable directories where anything (well, binaries at least) could be
executed from. I use Debian Linux 10 amd64. (I'm a home user.)

When I run `sudo find / -type d -perm -2` and remove from the listing the
directories which are on noexec-mounted partitions, just /dev/shm and
/dev/mqueue are left (and some docker directories in /var/lib/docker/overlay2,
to which I can't write as a normal user).

I assume that /dev/mqueue being exec-mounted doesn't have the same risks as
/dev/shm, as mqueue is not(?) an ordinary filesystem where one could save files
and execute them, right? (Or so it appears to me after some experimentation and
reading.)

The problem for me is mounting /dev/shm noexec -- I can't find where to do it. I
couldn't find a lot of information about this on the internet. The few sources
mostly only suggest adding it to fstab, but I'm hesitant about this as it isn't
there already. I'd rather change the settings at the source, where it's mounted
in the first place.

I also ran `grep -rwlsI -e shm` through /etc and /usr/share but didn't find
anything that would've looked like the mounting of /dev/shm, or where parameters
for it could have been changed.

So where can I change the mounting parameters of /dev/shm, or otherwise arrange
it so that /dev/shm is noexec already at/after boot?

(Out of curiosity, where is /dev/shm mounted from?)

(Additional suggestions regarding security are most welcome, too.)

Kind regards,

No, in resident memory you can find memory private to a process as well
as memory shared between processes.

And in memory private to a process, you can find resident memory and
non-resident memory.

According to Linux's Documentation/filesystems/proc.txt, we can find
this information in /proc/PID/status:

  VmData   size of private data segments
e.g.  VmData:  123004 kB

This looks like the amount of private memory, but I'm not sure.

2020-10-02 Thread Frank McCormick 
While compiling an application today my Debian bullseye system somehow 
got messed up. It will boot to a CLI but no X, apparently because for 
some reason the system is unable to access some files in 
/usr/share/dbus-1. It keeps saying access denied. The directories and 
files are owned by root, and if I noot to a CLI I have no trouble 
accessing them using sudo and midnight commander.


I tried reinstalling systemd but it ended with the same problem.

Can anyone help?

Exactly what I would suggest, and the opposite of my advice in
https://lists.debian.org/debian-user/2020/06/msg00598.html
where the problem was reversed. So you could hit all your replies by
modifying your attribution (as I have, above), but better would be
the hyphen in your sign–off (← as here) particularly if it's automated,
like mine. (I don't make my sign-off into a syntactical signature.)
I don't know how entirely 7bit attachments would be treated.

Note that you have been using Content-Type: … charset="UTF-8"
RFC 3156 says "many existing mail gateways will detect if the next hop
does not support MIME or 8-bit data and perform conversion to either
Quoted-Printable or Base64".

… which, of course, is nonsense. Since mid-August, I have been using a
different email smarthost for posts to just this list because two MTAs
are currently unable to cooperate successfully. Should I stay silent
until that bug is fixed? (Don't answer that!)

They obviously haven't read the RFC:

   "Implementor's note: It cannot be stressed enough that applications
using this standard follow MIME's suggestion that you "be
conservative in what you generate, and liberal in what you
accept."  In this particular case it means it would be wise for an
implementation to accept messages with any content-transfer-
encoding, but restrict generation to the 7-bit format required by
this memo.  This will allow future compatibility in the event the
Internet SMTP framework becomes 8-bit friendly."

So my guess is that your mailer is sending *potentially*
8bit content without encoding it, and an MTA is encoding it
because it's not expected to check for solely 7bit content
just because Content-Transfer-Encoding is set to 7bit.

Sorry that I can't check whether your signing is successful
as I don't maintain any personal keyring.

Cheers,
David.

I suggest identifying your workloads, how much CPU, memory, disk I/O, etc.,  
each requires, and then dividing them across your several computers.


Division across multiple machines... I am already doing this for data that  
exceeds my current 4T storage (2x2T HDD, 2x2T "slow" SSD local and 4x1T  
outsourced to the other machine). I currently do this for data I need rather  
rarely such that I can run the common tasks on a single machine. Doing this  
for all (or large amounts of data) will require running at least two  
machines at the same time which may increase the idle power draw and  
possibilities for failure?


Understand that a 4 core 5 GHz CPU and a 16 core 2.5 GHz CPU have similar  
prices and power consumption, but the former will run sequential tasks twice  
as fast and the latter will run concurrent tasks twice as fast.


Is this still true today? AFAIK all modern CPUs "boost" their frequency if  
they are lightly loaded. Also, the larger CPUs tend to come with more cache  
which may speed up single-core applications, too.


I would think that you should convert one of your existing machines into a  
file server.  Splitting 4 TB across 2 @ 2 TB HDD's and 2 @ 4 TB SSD's can  
work, but 4 @ 4 TB SSD's with a 10 Gbps Ethernet connection should be  
impressive.  If you choose ZFS, it will need memory.  The rule of thumb is 5  
GB of memory per 1 TB of storage.  So, pick a machine that has at least 20  
GB of memory.


4x4T is surely nice and future-proof but currently above budget :) I saw  
that the Supermicro AS-2113S-WTRT can do 6xU.2 drives. In case I chose  
Supermicro this would allow upgrading to such a 4x4T configuration.


As for the workstation, it is difficult to find a vendor that supports  
Debian.  But, there are vendors that support Ubuntu; which is based upon  
Debian.  So, you can run Ubuntu and you might be able to run Debian:


https://html.duckduckgo.com/html?q=ubuntu%20workstation


My experience with HP and Fujitsu Workstations is that they run well with  
Debian. I am still thinking that buying two systems will be more expensive  
and more power draw. Using one of the existent systems will slow some things  
down to their speed -- the current "fastest" system here has a Xeon E3-1231  
v3 and while it has 3.4GHz it is surely slower (even singlethreaded) than  
current 16-core server CPUs...


Thinking of it, a possible distribution accross multiple machines may be

* (Existent) Storage server (1U, existent Fujitsu RX 1330 M1)
  [It does not do NVMe SSDs, though -- alternatively put the disks
   in the VM server?]
* (New) VM server (2U, lots of RAM)
* (New) Workstation (4U, GPU)

For interactive use and experimentation with VMs I would need to power-on  
all three systems. For non-VM use, it would have to be two... it is an  
interesting solution that stays within what the systems were designed to do  
but I think it is currently too much for my uses.


Still, thanks for the suggestion.

Hello fellow list users,

I am constantly needing more computation power, RAM and HDD storage such
that I have finally decided to buy a server for my next "workstation". The
reasoning is that my experience with "real" servers is that they are most
reliable, very helpful in indicating errors (dedicated LEDs next to the 
PCIe

slots for instance) and modern servers' noise seems to be acceptable for my
working envirnoment (?)

I currently use a Fujitsu RX 1330 M1 (1U server, very silent) and it 
clearly

is not "enough" in terms of RAM and HDD capacity. A little more graphics
processing power than a low-profile GPU would be nice, too :)

Rack-Mountability is a must, although I am open to putting another tower in
there, sideways, should that be advantageous.

In terms of "performance" specifications, I am thinking of the following:

* 1x16-core CPU (e.g. AMD EPYC 7302)

* 64 GiB RAM (e.g. 2x32 GiB or 4x16 GiB)

   I plan to extend this to 128 GiB as soon as the need arises.
   As I am exceeding the 4T mark, I am increasingly considering the
   use of ZFS.

   Currently, I have the maximum of 32 GiB installed in the
   RX 1330 M1 and while it is often enough, there are times where I
   am using 40 GiB SSD swap to overcome the limits.

* 2x2T HDD for slow storage (local Debian Mirror, working data),
   2x4T SSD for fast storage (VMs, OS)
   I will do software-RAID1 (ZFS or mdadm is still undecided).
   I possible, I would like to use the power of the modern NVMe PCIe
   U.2 (U.3?) SSDs, because they really seem to be much faster and that
   may speed-up the parallel use of VMs and be more future-proof.

* 1-2x 10G N-BaseT Ethernet for connecting to other machines to share
   virtual machine storage (I am doing this already and it works...)

* a 150W GPU if possible (75W full-sized card would be OK, too).

Typical workloads:
data compression (Debian live build, xz),
virtual machines (software installation, updates)

Rarely:
GPGPU (e.g. nVidia CUDA, but some experimentation with OpenCL, too)
single-core load coupled with very high RAM use (cbmc)

Some time ago, there was this thread
https://lists.debian.org/debian-user/2020/06/msg01117.html
It already gave me some ideas...

I am considering one the following models which are AMD EPYC based (I think
AMDs provide good performance for my types of use).

* HPE DL385 G10 Plus
* Dell PowerEdge R7515

I have an old HP DL380 G4 in the rack and while it is incredibly loud, 
it is

also very reliable. Of course, it is rarely online for its excessive
loudness and power draw, but I derive that HPE is going be reliable? Before
the Fujitsu, I used a HP Z400 workstation and before that a HP Compaq d530
CMT and all of these still "function", despite being too slow for today's
loads.

I am also taking into consideration these, although they are Intel-based 
and

I find it a lot harder to obtain information on prices, compatibility etc.
for these manufacturers:

* Fujitsu PRIMERGY RX2540 M5
* Oracle X8-2L
   (seems to be too loud for my taste. especially compared to the others?)

I have already learned from my local vendor that HPE does not support the
use of non-HPE HDDs in the server which means I would need to buy all my
drives directly from HPE (of course this will be very expensive).
Additionally, none of the server manufacturers list Debian compatibility,
thus my questions are as follows:

* Does anybody run Debian stable (10) on any of these servers?
   Does it work well?

* Is there any experience with "unsupported" HDD configurations i.e.
   disks not bought from the server manufacturer?

   I would think that during the warranty period (3y) I best stay with
   the manufacturer-provided HDDs but after that, it would be nice to be
   able to add some more "cheap" storage...

* Of course, if there are any other comments, I am happy to hear them, too.

   I am looking into all options although a fully self-built system is
   probably too much. I once tried to (only) get a decent PC case and 
failed

   at it... I can only imagine it being worse for rackmount PC cases and
   creating a complete system composed of individual parts?

Thanks in advance

I suggest identifying your workloads, how much CPU, memory, disk I/O, 
etc., each requires, and then dividing them across your several computers.



Understand that a 4 core 5 GHz CPU and a 16 core 2.5 GHz CPU have 
similar prices and power consumption, but the former will run sequential 
tasks twice as fast and the latter will run concurrent tasks twice as fast.



I would think that you should convert one of your existing machines into 
a file server.  Splitting 4 TB across 2 @ 2 TB HDD's and 2 @ 4 TB SSD's 
can work, but 4 @ 4 TB SSD's with a 10 Gbps Ethernet connection should 
be impressive.  If you choose ZFS, it will need memory.  The rule of 
thumb is 5 GB of memory per 1 TB of storage.  So, pick a machine that 
has at least 20 GB of memory.



As for the workstation, it

Segun veo, el mensaje no esta claro:
- No tengo acceso a los ruteadoes.
_ NO es asunto de firewall.
_ Uso Buster, al dia.
_ NO tiene nada que ver si la IP, esfija o variable.

Gracias, por las respuestas; y espero que ahora, este mas claro.

Servers usually do not have a good GPUs - they are mostly not used.

Why don't you split your setup into powerful workstation and your current
server?

you could off load your virtual machines to dedicated hardware. Depends on
the number and configuration you indeed may need  a server for that -
better look at the requirements of the VM software manufacturer (VMWare or
Oracle or whatever else)

Servers are loud - same for DL380 G10, same for the PowerEdge

HPE does not support means not that you can not do it - rather you will not
have warranty/support in case of troubles. If you can live with it?

They use Seagate or Samsung disks - I am not sure ATM. Disks are disks you
can put whatever you want there. The disks they sell seem to be
manufactured specifically for HPE and likely are tested/certified by HPE,
although here one disk failed after 1,5y of operations in a conditioned
server room where the machine did not have much disk load. I mena it is
good to stay for the 3y with their hardware.
