[opensuse] Rsync over SSH with diffie-hellman-group1-sha1
by Paul Groves 19 Apr '20

19 Apr '20

Hi all. I have a question regarding SSH options with Rsync. I have an old NAS which I want to use to rsync some very large files to. I set up a user and a folder on the NAS. I can connect easily via sftp, although I need to specify an algorithm as follows. I need to use the following command. This works great and I can transfer files fine. sftp -oKexAlgorithms=+diffie-hellman-group1-sha1 paul@nas1:/mnt/array1/backup However, I cannot work out how to specify the the diffle-hellman-group1-sha1 on the rsync command. Can anyone shed some light on this please? So far I have the following: ~$ rsync -va /data paul@nas1:/mnt/array1/backup Unable to negotiate with 192.168.0.9 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: unexplained error (code 255) at io.c(235) [sender=3.1.3] Thanks Paul -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Emergency shell during times of intense swapping
by Richmond 05 Apr '20

05 Apr '20

I have 1.5 G of RAM, and from time to time I inadvertently get stuck with swapping overload. At this time it becomes difficult even to swap to the virtual console with ctrl-alt-f1, and having got there, even though I changed the login time-out to 10 minutes, sometimes it times out. Wouldn't it be a good idea if there were a way to get a shell with hi priority urgently? Perhaps there is. It would probably need to be on an interrupt like ctrl-alt-D. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Wireshark changes
by James Knott 02 Apr '20

02 Apr '20

I've noticed there have been some recent (March 13) changes to Wireshark. Previously, when starting, it was necessary to enter the root password. Now, no password is required, but it's no longer possible to select an interface to monitor. This makes it somewhat useless for capturing traffic. About all that can be done is read existing capture files. If opened from a root terminal session, it works normally. I then checked the application in the menu and found the application command had changed from /usr/bin/xdg-su -c /usr/bin/wireshark %f to wireshark %f, which runs it as a mere mortal, in that useless mode. Why was this done? After restoring the full command, it now works properly. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Why swap?
by James Knott 02 Apr '20

02 Apr '20

I'm running 15.1 & KDE. One thing I've noticed is swap use increases through time, even though I'm not even using all the real memory. Eventually, it gets to the point where my system bogs down and can become unusable. At the moment, I'm running 13.6 GiB of 15.6 memory and 4.1 of 24 swap. Why should swap be used at all, when there's still a significant amount of free memory? -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] NVIDIA nvcc (CUDA compiler) on Tumbleweed, and gcc versions
by Roger Oberholtzer 02 Apr '20

02 Apr '20

I have installed the NVIDIA CUDA RPMS on Tumbleweed. Although they are packaged by NVIDIA for Leap 15.1, they seem to have installed. I am trying to build some neural network software (https://pjreddie.com/darknet/yolo/). It works quite well as just a CPU-based program. However, I am hoping to use this to process many 10s of thousands of high-resolution images. So I want/need to build it with CUDA/GPU support. When running nvcc, I get a message that it does not support gcc versions newer than 8. On Tumbleweed, I have gcc 9. As one does. What is the best way to have two versions of gcc installed? I'm not sure exactly which gcc components nvcc uses. So I guess it would be the most of gcc8. Is it possible to install gcc8 in such a way that it does not become the default compiler? I plan on using it only for this purpose. The result should be a DSO library that I can then link against in my applications when they are built with gcc 9 or whatever the Tumbleweed default compiler is. As an alternative, anyone know if the CUDA package (https://build.opensuse.org/package/show/home%3ABumblebee-Project%3AnVidia%3…) in can be used in OBS? As it downloads things, I suspect OBS will not allow this. No idea. I also would need the version of gcc that CUDA 9 requires. Then I could build the package there, and have a new openSUSE package to boot. Pros and cons of both approaches? -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] network bonding slaves
by Roger Oberholtzer 01 Apr '20

01 Apr '20

We are setting up a cluster of computers that will be connected via a 10 GB network. The switch we are considering is something like https://www.netgear.com/business/products/switches/smart/XS748T.aspx The sales blurb says: Up to eight 10-Gigabit Ethernet links can be aggregated into a virtual 80‑Gbps connection In openSUSE, would this be related to bonding slaves? I have never used this. The goal would be that one computer (primarily a file server type of thing) has a high bandwidth stream for reading and writing data to the switch, where numerous other computers read and write via their single cable. This server would have, say, 4 10 GBit Ethernet ports connected to the switch. Ideally these would appear to be a single network. Am I thinking correctly? Anyone have any advice on this kind of thing? We are targeting an openSUSE Leap system for this server. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Question on KDM
by Dr.-Ing. Dieter Jurzitza 01 Apr '20

01 Apr '20

Dear listmembers, I am (AFAIK) bound to using KDM rather than i. e. using SDDM because I need two in parallel X11 - sessions running on tty7 and tty8 in my case. The disadvantage right now: because the resolution of my display is quite high (3840x2160) the fonts and the graphics of the login display are *very* small (too small for my old eyes :-)) Anyone having a solution on how to enlarge the size of the KDM login - window?
