Hi all.
I am soon to embark on a flurry of system documentation. As a part of
this, diagrams showing the layout of both hardware, software, data
flow and processing will be done. The things to be presented are
rather complicated in that there are many components and many
connections between the components.
I have done diagrams in the past, but have never been wowed by the
software. I'm sure a part of that is my experience with the software.
But I think that I might also have chosen poorly. Right tool for the
task and all that.
So, I am looking at the alternatives. My preference is something that
runs on multiple platforms (Linux and Windows). To be honest, a Web
tool it not out of the question. Except it would be nice to have the
diagrams saved locally for use over a long period of time. It is not a
one off thing. These diagrams need to be maintained and by perhaps
more than one person. At least over time.
Interactive diagrams where the viewer can click and get more details
or related diagrams would be nice. Having everything in a monster
diagram seems like a bad approach. On the other hand, including the
diagrams in other documents that might not be dynamic is needed.
So, if you have used any such tools (especially on Linux), what are
your experiences? And I expecting too much? I have looked at programs
like dia. It seems rather basic. But that might just be my knowledge
of what it can do. I have also used programs that let you specify the
diagram in a text file and it lays out the diagram. That has been fine
for simple diagrams. But when the diagrams reach any realistic
complexity, the layout is often something that one must struggle with.
All pointers are welcome. I have looked at various discussions of this
but they are typically so superficial that they provide no real
information. I am willing to investigate alternatives.

Hello,
I'm used for years to look at dmesg
I just noticed that in two of my 15.3 install (at least), this is no
more possible as user, with message:
dmesg: read kernel buffer failed: Operation not permitted
is this a new rule or some error on my system?
thanks

Hello,
I want to compare several hosting systems. For this I try to use
Bogomips as given on start dmesg.
However, on one of my systems, installed with JeOS on a vm, I get:
dmesg | grep Bogo
[ 0.000166] Calibrating delay loop (skipped), value calculated using
timer frequency.. 50.00 BogoMIPS (lpj=250000)
is there a way to get the Bogomips for this system?
(or any other simple way to estimate the machine speed)?
thanks
jdd

I've never had hardware newer than the distro to contend with. It might be enough
to install from repositories/Kernel:/stable/standard/x86_64/ or the 15.3 kernel,
but it might also require newer firmware or a newer xf86-video-amdgpu or even
Xorg. I'd try the 15.3 kernel first, but it might depend on something incompatible
with the 15.2 basesytem. If it won't install, I would expect the stable/standard
kernel would. Kernel is the place to start.

I am trying to setup a new machine with oS 15.2, but it is giving me only a
fall-back graphic resolution of 1024x768, even though the monitor has HD
resolution.
The graphics is built-in in the CPU:
AMD Ryzen 5 5600G with Built-in Radeon™ Vega CU Graphics
lspci describes the device as "[AMD/ATI] Cezanne", which sounds right.
But KDE is only offering this poor resolution.
Is there a way to achieve the higher resolution that the built-in graphics
can offer?

I downgraded one of my computers to 15.2 because this is the only
way to have a sound.
Now I installed the NFS server as follows:
At first I executed "zypper in yast2-nfs-server" for making "NFS
server" available to Yast.
Next I prepared an /etc/exports file and executed "Yast | Network
Services | NFS Server"
Finally I invoked "Yast | System | Services Manager" and started
"nfs-server" and "nfsserver".
But that did not help, the NFS server does not work, i.e. it is
impossibile to NFS-mount a file on a different computer.
What is wrong? Any help is welcome.
Thank you in advance,
Wolfgang
After I have removed the "References:" header, this message is no
more part of the thread entitled "Can't run NFS server".

For my purposes, a protection against exterior attacks would be
sufficient. But so far, I did not manage to set up firewalld
correctly. Having looked for "ssh" and "nfs" in all zones, I'm not
sure if there is some hidden occurrence left.
Thank you in advance,

I downgraded one of my computers to 15.2 because this is the only
way to have a sound.
After my NFS server problem has been solved now, I have one more
problem, i.e. I cannot access to this computer, called "pachew", by
ssh. When ssh is invoked from outside, no prompt for a password
appears, but any connection is immediately refused, and this error
message appears:
"ssh: connect to host pachew port 22: No route to host"
Any suggestions?
Thanks in advance,
Wolfgang

Hi,
Where I am at the moment I got a new router from a new ISP, that has both
2.5 GHz and 5 GHz bands. And it provides (ISP defaults) two SSIDs, one
"normal" and another at 5GHZ. Names like these:
sagemcomXXXX and sagemcomXXXX-5G
This is apparently typical of ISPs here.
Looking at network manager settings, I noticed that I can choose the band,
or set it to auto. All the settings are the same, I could use the same
configuration, and let automatics choose one or another band - but no, the
SSIDs are different.
If it were possible to tell NM in a single profile to use a different SSID
for each band, I could do that. The GUI certainly doesn't allow it.
It seems I'd better set the band manually on each of the two profiles (now
it is 'auto'), so they don't waste time probing.
I don't know if I should fuse both configs into one on the router, same
SSID - or not, I don't know what caveats there would be. And, here there
may be later other machines using Windows or Android.
One thing I noticed is that my laptop connects almost instantly. On the
old router, it could take several seconds to connect.
And a curiosity: if it can not connect, the XFCE desktop does not recover
the open apps of the previous session, it is empty.
Ideas, considerations?
