Re: [Trust] I spent a lot of time driving today

Ford clearly has a young Japanese guy or a young American fan of Transformers on its design team, too. The obnoxious uglification trend has been going on since the second Dubya Bush term, both in cars and pickups. You can see it clearly if you look at the generation photos in the brand nameplate articles in Wikipedia. For several vehicle generations, designs were pretty stable among, for example, Ford Taurus/Mercury Sable, Toyota Camry, and the F150 series of Ford pickups. Then the virus broke out about 2006 or so, and vehicle looks have been going from tolerable, to ugly, to unbearable. For the latter, see the front-end photos of the 2017 Toyota Camry. > Anyway, I disapprove of this trend. If I wanted to drive a paper airplane, rocket ship, or angry robot, I’d buy one of those. I might get one if they could fly, but given the damned traffic jam I was in, I suspect the Subaru SUV probably couldn’t fly or sprout huge treads or legs to climb over the rest of us or it would have. Chaos forfend that we have to start navigating in three dimensions instead of just two. Only the simplest automated driving in two dimensions can be accomplished now, and the entire system is not ready for prime time. The required automated technologies for three dimensional driving, which would be much more necessary than those for two dimensions, cannot be much more than ethereal flickers in unconscious brains, if they exist at all.

du Weirdness - how is this possible
by Philip Rhoades 14 Mar '18

14 Mar '18

People, I started deleting GBs of stuff from: /dev/sdb1 /backup but df did not reduce from 95% so I looked more closely and found this weirdness: # du -s -BG 20180216 43G 20180216 # du -s -BG 20180216/* 1G 20180216/naf_dirs 43G 20180216/phil 1G 20180216/root # du -s -BG 20180216/phil/* 1G 20180216/phil/0 1G 20180216/phil/0_finance 1G 20180216/phil/0_naf 1G 20180216/phil/Maildir 1G 20180216/phil/txts 1G 20180216/phil/vimwiki Where has ~37GB disappeared to? There are no files held open and I have successfully umounted and re-mounted the partition - what is going on?

looking for nonlinear optimizer with constraints accessible from python
by stan 14 Mar '18

14 Mar '18

I want to solve a small (a few hundred variables) nonlinear optimization problem with constraints in Fedora. I've found the scipy optimization routines, but they are for unconstrained problems. And there are the coin-or routines (ipopt, etc.), but they are not easily accessible from python. Fedora doesn't package pyomo, which can access them, so I've installed it to --user, but it seems like overkill, so I'm still looking. I would like something like pulp for linear programming; the closest I've found is pyOpt, and I like its interface, but it hasn't been maintained for 4 years, and it throws errors indicating that it might be incompatible with more recent versions of numpy (f2py) and multiarray. It can't find the shared libraries, compiled into python using f2py, of the fortran77 optimization routines it uses. So, before I go the pyomo route, does anyone have any recommendations for simple python accessible software that would do this in Fedora? Thanks.

selinux question
by François Patte 14 Mar '18

14 Mar '18

Bonjour, I have some alerts from selinux, for instance: SELinux prevent mdadm to access getattr on file /dev/shm/lttng-ust-wait-7-972 Why this alert? What should I do? This is not the only one, how to configure selinux to act in a "normal" way: leave regular processes to access what they need to work normally? Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte

PHP SOAP error after upgrade
by Chris Kottaridis 14 Mar '18

14 Mar '18

I finally got around to upgrading from Fedora25 to Fedora26. The layout is I have two partitions of which at any time one of the is the root partition, which contains everything but the /boot partition, and the other is not used. I have a separate /boot partition. When I upgrade I go into single user and duplicate the currently used root partition to the unused one using: # mkfs.xfs /dev/fedora/rootb # mount /dev/fedora/rootb /mnt # xfsdump -J - / | xfsrestore -J - /mnt Then I modify /boot/grub2/grub.cfg and tell vmlinuz to use the new partition and modify /mnt/etc/fstab to have the root partition be the new partition. I then reboot and indeed I come up on the new partition just fine, still running F25. On this new partition I do the OS upgrade. The upgrade goes fine and it boots up just fine on Fedora26. I did a search for .rpmsave files to see if the upgrade changed any configuration files I may have modified locally and that came up empty. However, when I try and use the application that runs on that machine which is PHP SOAP I get an error "can not connect to host". The nslookup for that host is correct and I can ping the host. As far as I know nothing has changed on that host. My code uses the following to handle self-signed certs: 'stream_context'=> stream_context_create(array('ssl'=> array('verify_peer'=>false,'verify_peer_name'=>false))) But I know that the cert on the host I am contacting is not self-signed. If I go back and edit /boot/grub2/grub.cfg to boot up off the old Fedora25 root partition it comes up fine and I can use the application just fine to connect to the host. Is there any history of PHP or SOAP having a change from F25 to F26 that could explain the "can not connect to host" error I am seeing on F26 that I don't see on F25 ? Thanks Chris Kottaridis

SELinux is blocking lightdm login to Xfce
by ToddAndMargo 13 Mar '18

13 Mar '18

Hi All, Fedora 27, x64 Xfce 4.12 lightdm-1.25.1-5.fc27.x86_64 With SELinux set to Enforcing, I can only log into Xfce as root. If I set SELinux to Permissive, I can log into anyone. SEAlert is quite. In the Audit log, I get: # grep lightdm /var/log/audit/audit.log | grep denied type=AVC msg=audit(1520843479.104:515): avc: denied { create } for pid=7554 comm="lightdm" name=".xsession-errors" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:samba_share_t:s0 tclass=file permissive=1 type=AVC msg=audit(1520843479.104:516): avc: denied { write open } for pid=7554 comm="lightdm" path="/home/tony/.xsession-errors" dev="dm-1" ino=54526689 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:samba_share_t:s0 tclass=file permissive=1 SELinux is taking a shine to everyone's, except root's, .xsession-errors. How do I fix this? Many thanks, -T

RH rpms, and installing using hardlinks vs symlinks
by Robert P. J. Day 12 Mar '18

12 Mar '18

i'm curious about RH packaging policy that dictates that some command variants are packaged for fedora to install with symlinks and others with hardlinks. trivial example in /usr/bin on my fedora 27 system: -rwsr-xr-x. 1 root root 52984 Aug 2 2017 at lrwxrwxrwx. 1 root root 2 Aug 2 2017 atq -> at lrwxrwxrwx. 1 root root 2 Aug 2 2017 atrm -> at so even though all of those "commands" are in the very same directory, atq and atrm are supported via symlinks, not hardlinks. OTOH, consider the "git" command, also in /usr/bin: -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git as you can see, there are 116 hardlinks to that executable, pretty much all of them in /usr/libexec/git-core: -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git-add -rwxr-xr-x. 1 root root 41441 Feb 16 15:03 git-add--interactive -rwxr-xr-x. 3 root root 2273360 Feb 16 15:03 git-am -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git-annotate -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git-apply -rwxr-xr-x. 116 root root 2273360 Feb 16 15:03 git-archive ... big snip ... is there a reason that "at" uses symlinks, while "git" installs with hardlinks? one would imagine that it would be the other way around -- given that the "at" variations are all in the same directory, hardlinks would seem to be the better choice since there is no possibility of crossing filesystem boundaries. also, what if i manually partitioned while installing, and put /usr/bin and /usr/libexec in separate partitions? (yes, i realize that's not the standard these days -- all of /usr defaults to a single partition -- but i'm assuming i still have the freedom to do something that unwise.) would git then switch to symlinks to support all those command name variants? just curious about how decisions like this are made WRT to packaging. rday

Amd Kaveri + AMDGPU kernel driver - any success?
by Clemens Eisserer 11 Mar '18

11 Mar '18

Hi, I would like to switch my AMD kaveri (7650k) based system from radeon to the amdgpu kernel driver. From what I've read, Kaveri is Southern Island and should be supported by AMDGPU. To force amdgpu i simply added "radeon.si_support=0 amdgpu.si_support=1" to the kernel command line, which had the effect that my system is now hanging at the "Starting Switch Root..." stage. Did I miss something or isn't the amdgpu kernel module maybe not included in fedora's initrd? Thank you in advance, Clemens

cups sucks!!!
by François Patte 11 Mar '18

11 Mar '18

Bonjour. I try to configure a printer on my local network but all attemps fail. I have a printer attached to one computer on an usb port and I want to use it with other computers on my local network. I opened firefox on one computer and miracle: the printer attached to the other computer is discovered and cups admin interface asks me if I want to add this printer. Nice: the job is easy!! *But* this does not work at all!! Sending a test page returns that the printer is not responding. I tried to cofigure the printer using the "Add printer" way and chose ipp. According to the given syntax, I wrote: ipp://name-of-server/ipp but this does not work: sending a test page returns that the printer is misconfigured or no longer exists... I replaced the name of the server by its IP address... same result. I tried: ipp://name-of-server:631/printers/name-of-printer-on-server. It does not work, the message is now: Filter failed. What fiter? I don't know as cups logs no longer exist since systemd... Does somebody know a solution? Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte
