Sending a desktop to a big screen
by Amit Prahesh 18 Aug '15

18 Aug '15

Hi there, imagine a medium sized office room, where four engineers hack away (all of them currently have Fedora 22 workstations, to stay on topic.) On that room there's a fifth PC, hooked to a big TV on the wall (also running F22) that has Firefox running full screen with some visualization of sorts (dashboard thingy). Those five computers are all on the company wired network... nothing you haven't seen a thousand times before. Now, Sally, one of the engineers wants to share her desktop with the others and uses application XYZ to project/cast/extend/send it to the big TV (via its PC, of course). All of them discuss whatever was on her mind, and five minutes later, she closes application XYZ and the office goes back as it was before. Fred wants to do the same, and he does. Actually all of them can. They asked me what is XYZ. I was thinking on a member of the VNC family, but what they want to do is the reverse of what one normally do with VNC. To make things more... interesting? XYZ must never go out of the corporate LAN and if it were Open Source, the better. Any ideas on XYZ? Best regards, Amit. PS. Erm... one last thing. If there's a solution, could it include sending the audio as well?

slow loading https:\\facebook
by Paul Cartwright 18 Aug '15

18 Aug '15

I am having an issue using chrome & loading facebook. It stalls, doesn't load. This is a new fedora 22 installation. I had this issue with my old computer, but I fixed it by disabling IPv6. I thought I did that already, but it is still loading slowy. Other https:\\ sites are quick. any suggestions? I already set my MTU to 1492. hmmm, I just tried it with Firefox and it is fast, so it seems like it is a chrome issue, add-on maybe?? what add-on would slow it down? -- Paul Cartwright Registered Linux User #367800 and new counter #561587

Re: dnf --refresh reverts to older metadata (was: Re: dnf update vs Software Udpates)

That would be an odd way to put it. =:-/ Would you rather prefer silence and people returning to another distribution? I mean, it is not clear yet whether mirror manager is the culprit, is it? Also, it's very unlikely that the dnf developers use only bugzilla for all project management, such as todo lists and milestone target details. Now that you've learned there is some fundamental problem, it should be put onto some internal todo list to schedule some proof-reading of the implementation and sit together with the mirror manager guys. Very important would be to verify all the stuff around the metalink XML parsing and evaluating, especially the age/timestamp/checksum/alternates. Adding more helpful debug output would be an idea, too. Certainly it should be possible to print metalink data age, which would be much more relevant than the time of the last metadata expiration check. > + output of these command sequence (to see which mirror is picked) > # export LIBREPO_DEBUG=1 && dnf update --assumeno > # export LIBREPO_DEBUG=1 && dnf update --assumeno --refresh > # dnf clean metadata > # export LIBREPO_DEBUG=1 && dnf update --assumeno This does not print "which mirror is picked". It does not print anything helpful at all. I would expect debug information to include some details about the metalink server response, the metadata checksum and the metadata age, and stuff like that. | Librepo version: 1.7.16 with CURL_GLOBAL_ACK_EINTR support (libcurl/7.44.0 NSS/3.19.3 Basic ECC zlib/1.2.8 libidn/1.32 libssh2/1.6.0 nghttp2/1.2.0) | lr_download: Target: file:///etc/dnf/dnf.conf (-) | select_next_target: Selecting mirror for: file:///etc/dnf/dnf.conf | prepare_next_transfer: URL: file:///etc/dnf/dnf.conf | add_librepo_xattr: Cannot set xattr user.Librepo.DownloadInProgress (fd: 5): Operation not supported | lr_download: Downloading started | check_transfer_statuses: Transfer finished: file:///etc/dnf/dnf.conf (Effective url: file:///etc/dnf/dnf.conf) | Fedora - Rawhide - Developmental packages for t 1.4 MB/s | 43 MB 00:29 | Adobe Systems Incorporated 23 kB/s | 1.8 kB 00:00 | Last metadata expiration check performed 0:00:00 ago on Tue Aug 18 12:25:42 2015. | Dependencies resolved. > Michael, have you run all these commands at one moment or after 1 day > breaks?

POC - Store config files for docker containers.
by oleg＠gashev.net 18 Aug '15

18 Aug '15

Hi, The question is: "how to containerize an application in such a way that it allows the end user to customize configuration files?". Another question: how to containerize application for multiple environments? We have some ways to do this: create two different Dockerfiles for each environment, use environment variables, generate config files on the fly , using templates, etc. Another way - using Docker mounted volumes: bind mount a volume from the host into the container. How to create container and how to create config files? For POC I use nginx application. I updated nginx spec file and separate nginx.rpm on two different rpm files: nginx-data and nginx. nginx.rpm consists of the application files, nginx-data.rpm consists of config files and html files. nginx-data.rpm will be install to the host. nginx.rpm will be install into the container. For containerization of the nginx.rpm created Dockerfile to build nginx image with the nginx.rpm file. This image stored in the docker-nginx.rpm file. Installation # rpm -ivh http://overbits.org/docker/releases/22/x86_64/os/overbits-org-docker-releas… # dnf install docker-nginx # systemctl start nginx docker-nginx rpm package install docker nginx image. nginx config files (/etc/nginx) and html files (/usr/share/nginx) install to host. nginx application will install in the nginx docker image. Install systemd nginx.service file. On call systemctl start nginx create new container to run nginx service. Source code, spec files, jenkins jobs, etc: http://overbits.org/cgit Thank you. -- Oleg Gashev

cfg80211 messages repeat every 120 seconds
by Chris Murphy 18 Aug '15

18 Aug '15

I have an odd duck Internet setup that I have no control over. It's slow and often unreliable, but I'm particularly curious about all of these messages that stream into the journal. http://ur1.ca/ngum5 Maybe the best part is that even gnome-session is confused about this arrangement: "An active wireless connection, in infrastructure mode, involves no access point?" Any ideas? This is not a high priority question. -- Chris Murphy

Paul, I recently went through the steps to install NVidia drivers for my Video card on F22-64. It resulted in the X screen not running, and it took awhile to troubleshoot by using console commands. Now I'm using the Nouveau drivers and I'm doing fine. If you need the special features of the proprietary driver, I would recommend using the dnf software packaging system in fedora. If things go wrong, you can roll back the install.

deprecated message in dmesg
by Tom Horsley 17 Aug '15

17 Aug '15

This cryptic nonsense shows up in the output from dmesg: automatic filtering via arp/ip/ip6tables has been deprecated. Update your scripts to load br_netfilter if you need this. So how would a mere mortal know if he needs br_netfilter or not?

by Mickey 17 Aug '15

17 Aug '15

Fedora 21/ KDE I'm trying to run a App called apmplanner2 but it is not giving the user jim permission of using the serial ports. the user owner of apmplanner2 is jim. When I try to run apmplanner2 I get a error message saying to run "sudo adduser jim dialout" And the I get linux error on usage of adduser, something like adduser -D but that still does not work. What am I not doing right ?

[1] Neither "dnf --refresh upgrade" nor "dnf clean expire-cache;dnf upgrade" will try to download the base Fedora data (F22). Only "dnf clean metadata" plus "dnf upgrade" force a full refresh. Just try it out. "--refresh" and "clean expire-cache" result in the same. That also matches the documentation. Both set the metadata some kind of expired but don't really remove the data. "dnf clean metadata" actually removes all metadata and therefore forces a reload for all repositories. It's more like brute force. :-) Also according the the DNF documentation (FAQ), "dnf clean metadata" is the recommended way to get latest updates. That matches my experience. Greetings, Andreas
