Can this help: https://apple.stackexchange.com/questions/39504/best-way-to-copy-all-files-ignoring-errors,,hotmail I do not know. ... I put in a DVD and try to copy the data to HD mc is saying: Cannot copy. Do You want to ignore the DVD? I do not know mc, but what you describe is definitely not a full description of an error. Probably because mc is designed to hide those. In that case, you'd have to look at lower levels to actually see what is going on. I think there was a bug during burning. One important step in solving problems is identifying the problem. That latest statement of yours indicates that you have not yet done so. You need to get beyond the stage of assuming, believing or thinking something might have happened -- you need to know. Is "dd" the best idea? Quite surely not. Better find out what actually is on your DVD first. I have not worked with DVD writing for at least 10 years, and I do not intend to in the future, but I'm sure there are tools that can tell you about sessions and whatever you can have on the different flavours of writable DVDs. Once you know that level is good, you'll start to look at file systems. After that, eventually, files and copying *may* become relevant. I would propose you just stop spending time on those topics all those details may not be interesting to you. On the other hand, if the data is really important, it's time to start learning about how DVD writing actually works. A mailing list is not going to be very efficient here, better start differently, for example here: http://fy.chalmers.se/~appro/linux/DVD+RW/ and follow the links and make sure ypu actually understand those information. You probably will need a few packs of writable DVDs because experimenting and failing can be invaluable elements of learning. It can actually be fun.

Re: Network tcp/iptables issue with XRDP

Trying to bring up XRDP service on Debian 11-bullsyeye (arm64, incl. backports, fully up-to-date) which is only listening on „lo“ interface (not eth0) even netstat indicates otherwise: -> incoming tcp syn/ack on localhost interfact (lo) works fine -> incoming tcp syn/ack on eth0 interface seems not to reach app listening process (while other services on same host are working just fine via the network - so it’s not an „physical" network issue). -> iptables are cleared and not aware of any other netfilter running… I suggest to verify the other netfiler options. Recently I encountered something similar, and my usual test for local firewall being active, iptables -L -n came back with policies "accept" all over the place, and no particular rules.

OpenCL with Radeon GPU
Hi all, I'm currently trying to set up a new workstation and wanted to enable OpenCL for future use. GPU hardware is an AMD Radeon RX 6750 XT. I have a base installation of Debian 12 up and running, kernel 6.1.0.7 including amdgpu and Mesa 22.3. Any attempt to actually run any OpenCL program results in an error: fatal error: cannot open file '/usr/lib/clc/gfx1030-amdgcn-mesa-mesa3d.bc': No such file or directory which is depending on the using program reported more or less easily visible. clinfo is sufficient to show this. Trying to diagnose this with available documentation I learned that - I am not even able to determine if OpenCL itself should work, - if it should work with the hardware I have here, - which versions of amdgpu, xserver, Mesa, llvm or clang I need or which particular drivers / packages to install I have tried several versions of the possible packages, but lacking documentation that makes sense to me that was more like blindly poking in the dark. I even tried following some advice to use AMD's out-of-kernel driver pack, but the installation script stumbles over dependencies (which may or may not be due to the not-yet-stable base distro). Anyway, the current state is less than satisfying, because I don't even understant if OpenCL with Radeon RX 6xxx GPU can even work on Linux. I would give a different distro a try, but as a mostly-Debian-person I'm not really inclined to start learning to maintain more distros. Just using Windows would be a solution I would not appreciate at all... So, my question here: Can anybody confirm this can work in general, or even point me to a place for current, correct documentation? Alternatively, a pointer to where I short report those problems -- Debian bug (which package?), freedesktop.org's mesa, Linux kernel developers would be appreciated.

Re: OpenCL with Radeon GPU
Hi all,
a bit of research resulted in me finding this (old) page, which
indicated there were some environment variables I could use to control
memory allocation of AMD's OpenCL implementation:
https://community.amd.com/t5/drivers-software/solved-clinfo-reports-error-33-of-quot-global-free-memory-amd/td-p/172760
So I decided to give that a try.
First step: Ensure I can run an OpenCL program from the shell. I used
the Primegrid binary for that:
#
/var/lib/boinc-client/projects/www.primegrid.com/genefer22g_linux64_22.12.02
-h

Command line: '-h'
Running on device 'gfx1031', vendor 'Advanced Micro Devices, Inc.',
version 'OpenCL 2.0 ', driver '3513.0 (HSA1.1,LC)'.
33000^{2^15} + 1: 00:00:35, 0.0386 ms/bit, data size: 1.12 MB.
2^{2^16} + 1: 00:01:28, 0.0489 ms/bit, data size: 2.25 MB.
12000^{2^17} + 1: 00:04:35, 0.0784 ms/bit, data size: 4.5 MB.
1800^{2^18} + 1: 00:14:01, 0.133 ms/bit, data size: 9 MB.
550^{2^19} + 1: 00:49:15, 0.252 ms/bit, data size: 18 MB.
200^{2^20} + 1: 01:58:46, 0.325 ms/bit, data size: 24 MB.
91^{2^21} + 1: 07:04:18, 0.613 ms/bit, data size: 48 MB.
27^{2^22} + 1: 25:34:55, 1.22 ms/bit, data size: 96 MB.
100^{2^22} + 1: 30:51:50, 1.33 ms/bit, data size: 96 MB.
50^{2^23} + 1: 116:24:31, 2.64 ms/bit, data size: 192 MB.
So that worked.
It also did not cause an error, but of course, test data != real
workload, right?
Next step Ensure I can reproduce the error:
#

0.0202% done, 28:15:37 remaining, 1.21 ms/bit.
Interesting, this seems to work without problem. Right now, I'm at
7.29% done, 26:21:57 remaining, 1.22 ms/bit.
which is much longer than what I've seen before.
My conclusion for now: The boinc service must have some limits set.
systemctl show gives me, among others:
LimitCPU=infinity
LimitCPUSoft=infinity
LimitFSIZE=infinity
LimitFSIZESoft=infinity
LimitDATA=infinity
LimitDATASoft=infinity
LimitSTACK=infinity
LimitSTACKSoft=8388608
LimitCORE=infinity
LimitCORESoft=0
LimitRSS=infinity
LimitRSSSoft=infinity
LimitNOFILE=524288
LimitNOFILESoft=1024
LimitAS=infinity
LimitASSoft=infinity
LimitNPROC=253399
LimitNPROCSoft=253399
LimitMEMLOCK=8388608
LimitMEMLOCKSoft=8388608
LimitLOCKS=infinity
LimitLOCKSSoft=infinity
LimitSIGPENDING=253399
LimitSIGPENDINGSoft=253399
LimitMSGQUEUE=819200
LimitMSGQUEUESoft=819200
LimitNICE=0
LimitNICESoft=0
LimitRTPRIO=0
LimitRTPRIOSoft=0
LimitRTTIME=infinity
LimitRTTIMESoft=infinity
My first candidate would be LimitMEMLOCK as I suspect that, for
interaction between GPU and CPU, shared and locked would be a likely
way. (You notice I know nearly nothing of OpenCL...)
I do know how 'systemctl edit' works, though, and set the limit to 1 GB:
LimitMEMLOCK=1073741824
LimitMEMLOCKSoft=1073741824
Which did not help, same error after similar time.
Still, seeing that I can run the binary in question from the shell, I'm
kind of confident this should be solvable via proper unit configuration.
Which leaves me with one question for this mail thread: Can anybody
recommend a test program for OpenCL functionality?
Thanks,
Arno

Unfortunately there are more steps ahead, as any Primegrid task using the GPU fails with an error: opencl error: CL_OUT_OF_HOST_MEMORY As I have no other real OpenCL workload I can try with any reliability, and I also have lots of host memory available, I suspect this due to the messy state of the software or its installation. And, as the installation has definitely not been done in any documented manner, I would not be surprised if that's the problem.

Re: Why does Debian have code names for releases?
Hi all, I have read a few replies here. I am in no way affiliated with those people who originally introduced the names or assign them now. The only real answer to the actual question that I can see is "It's a tradition". Also, I struggle with the names, always need to go to the project web page or wikipedia if I need to look up which version has which name, and it's always a nuisance. A small one, though. Also, I really like the Debian project, its resulting software collections, and thus my wish is to keep those code names, as inconsistent and hard to memorize they are. It's Debian, and I like it. I still have etchnhalf running on two old boxes, even :-) Oh, and also, for any sort of managed installation all this would not matter much.

OpenCL, boinc, and systemd resource limits
Hi all, back to trying to get OpenCL-based boinc workloads running. It appears that the AMD-provided OpenCL stack works to some extent under Debian 12. However, I have some problems with OpenCL-Using boinc-managed PrimeGrid programs. I do get an error that seems to indicate some resource limit being involved: Error: opencl error: CL_OUT_OF_HOST_MEMORY when I run the boinc client through systemd. If the boinc client is run from the shell, for example as sudo -u boinc boinc in its proper working directory, everything behaves correctly. Given the circumstances I suspect some sort of limit on memory. I just have no idea how I can diagnose this further, or even how to fix it. An attempt with a unit file override with [Service] LimitMEMLOCK=1073741824 LimitMEMLOCKSoft=1073741824 was not successful. Does anybody have an idea, or can share recommendation where to ask for more advice? (Debian project, i.e. here because this might be integration / packaging related, freedesktop.org for systemd, boinc project, perhaps -- trying to get assistance at PrimeGrid did so far not result in anything helpful.)

How does a breaking USB disk differ from a breaking SATA disk? My own experience is that it's often harder to notice and diagnose -- because on top of the actual storage and its "native" interface such as SATA or NVMe/PCIe, you have the whole stack of USB things. And misbehaving USB devices usually result in first working on the USB end -- try different port, port directly on mainboard, or a powered hub, watch out for native USB 3 or 3.0 Gen 1 -- we can see this on this mailing list, too. Then, USB storage is usually a single device single, if it breaks, it's data is lost, whereas SATA/SAS/NVMe can more easily be integrated into redundancy providing systems. On top of all that, my own, admittedly anecdotal, experience is that USB/Firewire-to-IDE/SATA adapters and their power supplies are more fragile than actual disks. Most of the external hard disks I ever used have been replaced because of their enclosures or power supplies failing. So, I tend to agree with Andy, and I also don't notice any moving goalposts in his statements... In my experience it happens more often and also brings with it frequent issues of poor performance and other reliability issues like just dropping off the USB bus. There is almost always a better way. For home users / small office environments, that leaves the problem of how to do backups -- USB drives are the most appealing storage system for such purposes, but also seem to be less reliable than the primary storage. What do you do? Throw more of the USB disks onto the problem? Or is "public" cloud the solution? Whatever you do, even purely personal storage requirements become a bit of a nightmare when you start thinking about how to make sure your photos and videos are around when your kids are grown up...

But even I will do so, still all files will be copied to the livefilesystem, this makes no change. Well, I think this is what you can expect when using a tool to essentially copy your running Linux to a DVD image. You asked me, what I want. Simple: I am running KALI-Linux on one of my notebooks· with encrypted partitions. As my KALI got some tools, which need lots of plugins, has added some software NOT in the KALI-repo and got several personal settings, I could not build a livefile system of KALI by using live-build. I'll try to not digress into why you would want to use a heavily modified Kali in the first place, and then copy it to a different media, which probably results in something quite unmaintainable ;-) ... Everything is working perfectly, except this little annoying at boot. So I understand you want the exact same system as you run it on the host, *but* without the file systems mounted. Here we reach the point where I must admit I do not know how bootcdwrite works :-) However, from its documentation, I conclude it essentially puts all system configuration into its target directory tree, but it will have to modify some of it -- for example, if / is mounted from the live file system, a mount point in /etc/fstab for / would be counterproductive. The tool, accordingly, has to modify all the fstab entries for the file systems it copies. That seems to work, as you state above. Also apparently, the underlying block storage setup *is* copied. Your goal seems clear, you do not want that block storage to be accessed, so you'd have tomake sure the necessary setup is *not* copied. Depending on the stack you use, that could be md, lvm, luks, and possible more stuff. Now, where do you draw the line? I, for example, would prefer to have md automatically trying to assemble any RAID it may find, and LVM to kick in, too. Matters of taste put aside -- I think you can use the extra_changes() function in the configuration to mangle the respective configurations according to your needs. Removing entries from fstab and crypttab would possibly be sufficient, but if the created image makes use of your existing initrd, you might have to modify that as well. In that latter case, I would probably decide that the modifications are so invasive, that the idea to call this a "copy" of the origin system is no longer true, and just using a generic live / rescue system may be easier. Besides: Doing so, is a great advantage, as you might agree: I can make a livesystem from a server, then boot it and now can dangerousless test different configurations, can install packages, can test special settings and so on. Just without to harm any productive system. That appears to be too much overhead to me... virtual machines (for server as full OS) seem much more appropriate to me, in particular as differences between in-VM and physical devices are pretty much (not completely, though!) abstracted away these days. If a real, identical piece of hardware is needed for such projects, I would rather invest money than time and still carry the risk to accidentally destroy a production system, which also would, by necessity, be down for whenever I experiment. Which would at least make comparisons of behaviour much more difficult. And after testing, I can easily change the well tested configurations to the productive server! Two advantages, as you see. My views are quite different, but that may be because I'm working too much in environments where lab - staging - production systems are prescribed anyway, and configuration is engineered in labs and eventually deployed through automated systems. Does this make things a little bit clearer? Definitely clearer, but I suspect you'll eventually have to put a lot of your own effort into your final solution, as the general idea is rather specific.

That's a problem -- it is not Debian. Expecting insight here is a bit of a stretch. It would be much better to check with the actual distribution provider. Greg's advice about upgrading is demonstrating the versions for the x86_64 platform. This may or may not be directly applicable to your distribution. However, trying to upgrade something non-Debian with Debian packages may be exciting and provide great learning experience, but rarely is a smooth process. I would propose to head over to https://www.raspberrypi.com/software/ if you do not get very clear advice here. Also, the actual software you want to use should be considered. If it's not packaged for your distribution, it's at least clear the packager does not guarantee anything. Rebuilding for your platform requires access to source code and (possibly) build environment. Suggestions or advice require you to disclose what you're actually looking at. Good luck! Arno -- Arno Lehmann IT-Service Lehmann Sandstr. 6, 49080 Osnabrück
Re: using mbuffer: what am i doing wrong?
Hello, I have not used mbuffer for a long time, so won't comment on that. But your netstat call looks unsuitable to diagnose. I'd propose to use ss -f inet -lpn ss instead of netstat... I try to catch up with changing times :-) -f inet because in this case, you're (probably) just interested in IPv4 network sockets. Could be IPv6, of course, then use inet6 -l list listening sockets, not active connections -p show the process using the socket. Will usually require root -n show numbers, not translated names l and n are probably most important for you (and are also available for netstat) as you would otherwise first miss a listening socket, and then have grep miss the output if you use a port number that is assigned (see /etc/services) Good luck!

Re: systemd and timezone

I'd change it immediately, but I don't want to make a change that isn't correct. Was this paragraph actually correct for Etch? Was /etc/localtime a literal *copy* of a file instead of symlink? If so, when did it change? Or, was this wrong for Etch, and /etc/localtime was always a symlink? I have Etch running here, and the /etc/localtime file is not a symlink, nor a hardlink to a zone file: TomBombadil:~# ls -lhi /etc/timezone /etc/localtime 159667 -rw-r--r-- 1 root root 842 2020-11-14 18:27 /etc/localtime 140 -rw-r--r-- 1 root root 14 2020-11-14 18:27 /etc/timezone TomBombadil:~# ls -lhi /usr/share/zoneinfo/Europe/Berlin 186905 -rw-r--r-- 1 root root 842 2008-10-17 18:57 /usr/share/zoneinfo/Europe/Berlin TomBombadil:~# diff -q /usr/share/zoneinfo/Europe/Berlin /etc/localtime ; echo $? 0 TomBombadil:~# cat /etc/debian_version 4.0 Cheers, Arno
Re: sid
Hi Michael, your problem report is a bit difficult to comment upon. First, this is a debian users mailing list. I think nobody here will feel that they "are" Debian. Then, you have problems with Sid. Now, Sid is the unstable development version of the distro. On the web page describing the different releases, https://www.debian.org/releases/ the authors stated very clearly that Sid might not work and even mentions disfunctional updates as an example. They also state that users of Sid should subscribe to debian-devel-announce. My conclusion is that problems with Sid should be discussed with the developers community. And, considering that you tackled a development release, I think it would be useful if you provided details about the problem -- not just the result as in "network doesn't work anymore" but rather some observation of *why* -- which may be software packages that are essential for networking were uninstalled during the upgrade, or provide binaries that do not work. Without such information it will be hard to work on fixes. Also, you write There are something over a hundred sites and pages up, that give simple logical instructions about how you install Debian and upgrade to sid. Every one of those pages is currently wrong. but this is not something the audience of this mailing can take responsibility for. If you address the right audience with your observations, the problem you found may be fixed. Here, it's unlikely you can get better results than pointers into other directions or just questions of "why Sid?". Best, Arno
