Adding a file share service to Thunderbird
by JD 03 Feb '15

03 Feb '15

Often I want to attach a file that is larger than what google will allow, a limit I configured in TB. And TB will prompt me to use a file share service. The problem is I do not want to use the 2 file share services that TB is showing, and none of the add-on have my preferred file share server. Has anyone somehow overcome this "apparent" limitation of TB, and configured TB to use a file share service other than what TB and the plugins (add-ons) provide?

DHCP Reservations
by Jim Lewis 03 Feb '15

03 Feb '15

Hello all, Quick question about DHCP reservations: I have laptops with both wired and wireless NICs, is it okay to have the router assign the same IP to both interface? I am assuming it will let me do that. I will not, and do not ever, have both interfaces active at the same time. In order to make this post at least somewhat relevant to Fedora I am currently running three of them in my home office. I keep thinking that I am missing something, possibly obvious, as to why I shouldn't do this. I have my new Netgear R6200v2 working perfectly and I don't want to do anything to piss it off.

Ip route issues
by Jarmo Hurri 03 Feb '15

03 Feb '15

Greetings. Something changed in our work network configuration or my Linux laptop around Christmas. I now have serious network issues. The following happens all the time. ---------------------------------------------------------------------- 1. I am unable to contact a server http://en.wikipedia.org/ Browser says ERR_ADDRESS_UNREACHABLE 2. Name server works just fine [jarmo@localhost tmp]$ dig en.wikipedia.org +short 91.198.174.192 3. traceroute shows issues [jarmo@localhost tmp]$ traceroute en.wikipedia.org traceroute to en.wikipedia.org (91.198.174.192), 30 hops max, 60 byte packets 1 localhost.localdomain (172.16.43.148) 3004.217 ms !H 3004.195 ms !H 3004.187 ms !H 4. The problem is solved temporarily by flushing the route cache [jarmo@localhost tmp]$ ip ro get 91.198.174.192 91.198.174.192 via 91.198.174.192 dev em1 src 172.16.43.148 cache <redirected> [jarmo@localhost tmp]$ su -c "ip route flush cache" [jarmo@localhost tmp]$ ip ro get 91.198.174.192 91.198.174.192 via 172.16.40.1 dev em1 src 172.16.43.148 cache Now the address works ok for a while, but then I get connection problems again quite quickly. ---------------------------------------------------------------------- I have no idea whether the problem is in my laptop or in the network. I have no problems in other networks. On the other hand, Windows machine in this network work without issues. Any ideas? I am running an up-to-date Fedora 20 with [jarmo@localhost tmp]$ uname -a Linux localhost.localdomain 3.17.8-200.fc20.x86_64 #1 SMP Thu Jan 8 23:26:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux [jarmo@localhost tmp]$ yum info iproute Loaded plugins: langpacks, refresh-packagekit Installed Packages Name : iproute Arch : x86_64 Version : 3.14.0 Release : 2.fc20 Jarmo

5tFTW: FESCo Vote, Fedora Swag, Stats, Job Opening, and CentOS & EPEL (2015-02-03)
by Matthew Miller 03 Feb '15

03 Feb '15

Fedora is a big project, and it’s hard to keep up with everything that goes on. This series highlights interesting happenings in five different areas every week. It isn’t comprehensive news coverage — just quick summaries with links to each. Here are the five things for February 3rd, 2015: Vote now in FESCo Elections --------------------------- The election for Fedora 22 – Fedora 23 members of FESCo (the Fedora Engineering Steering Committee) is now open (through 00:00 February 4th — note that that’s *today*, Tuesday, February 3rd — and early evening in the United States). Read interviews with candidates here: - Debarshi Ray (rishi) * http://fedoramagazine.org/fesco-elections-interview-with-debarshi-ray-rishi/ - Parag Nemade (paragan) * http://fedoramagazine.org/fesco-elections-interview-with-parag-nemade-parag… - Tomas Hozza (thozza) * http://fedoramagazine.org/fesco-elections-interview-with-tomas-hozza-thozza/ - David King (amigadave) * http://fedoramagazine.org/fesco-elections-interview-with-david-king-amigada… - Kevin Fenzi (nirik) * http://fedoramagazine.org/fesco-elections-interview-with-kevin-fenzi-nirik/ Adam Jackson (ajax) and Alberto Ruiz (aruiz) are also running but no interviews area available. See the Elections wiki for each candidates’ self-nomination. Read the interviews, and then vote! (Note that the Environments and Stacks Working Group had a number candidates equal to the number of open slots, and so decided no election is necessary for that group.) * https://fedoraproject.org/w/index.php?title=Development/SteeringCommittee/N… * https://admin.fedoraproject.org/voting * https://lists.fedoraproject.org/pipermail/env-and-stacks/2015-January/00066… Get Swag from the Fedora Store! ------------------------------- Thanks to Ruth Suehle, we now have an official store for Fedora-branded swag. As Ruth explains, we’re leveraging Red Hat’s “Cool Stuff Store” for this, because it helps us with legal obligations as well as inventory and financial requirements. This is a sort of trial run, with four items to start. If it’s successful, we can have more (and possibly look at expanding to other countries — we are very aware that the current international shipping prices are… not great). (I see that many shirt sizes are already out of stock, so that’s a good sign!) Also note: these items are priced at our cost; Red Hat and Fedora aren’t making any money this way (we really can’t, even if we wanted to). It’s just an easy way for you to get Fedora-branded gear. * https://redhat.corpmerchandise.com/ProductList.aspx?did=20588 * https://lists.fedoraproject.org/pipermail/announce/2015-January/003251.html Fedora Job Opening: Infrastructure Engineer ------------------------------------------- The Fedora Infrastructure team headed by Paul Frields has a new opening! See the Red Hat Jobs page for full details, but the quick summary is that we’re looking for a software engineer / programmer with experience in continuous delivery to help the Release Engineering team build the next generation of the tools we use to produce Fedora. The job listing came out highly slanted towards Project Atomic, as that is the current hotness, but don’t expect to be pigeonholed there. Do you have experience as a site reliability engineer? Is your instinct to develop systems to pass arbitrary condiments? Have you been doing actual devops for so long that you just sigh about how the term is used today? Does Fedora’s six-month release cycle seem disturbingly slow — and you know what to do about it? This may be the job for you! (Note that the job is listed as in Raleigh, North Carolina, but we are open to applicants worldwide.) * http://jobs.redhat.com/jobs/descriptions/lead-engineer-fedora-project-atomi… * http://xkcd.com/974/ Fedora Yum Connection Stats --------------------------- More on this later, but here’s a chart Stephen Smoogen put together for my presentations at FOSDEM and DevConf.cz: > http://fedoramagazine.org/wp-content/uploads/2015/02/fedora-os-all-mov_avg-… The data counts updates-mirror connections from the same IP address a single time a day. Smooge notes that a large number of caveats should be considered, including changing use of NAT over time and increasingly short DHCP leases. Also, this almost exclusively counts North America and Europe, where cheap always-on Internet is commonplace. And, of course, it only counts systems which actually check for updates regularly; many don’t. So, with all of those caveats aside, there are some interesting points. There’s a general third/third/third split in updating: when new Fedora release comes out, a third of users update almost immediately, another third update by end-of-life when the “N+1″ release is out, and the final third are end up as a long tail which persists forever. The chart basically starts with Fedora 6, and as you can see, Fedora 8 was very, very popular. If you take F8 out, you see a general period of growth in the peaks from F6 onward, until we hit Fedora 15 (a release with a lot of change, including systemd and Gnome 3). Those users didn’t *leave*, though — they just didn’t update, and F15 *never* exceeded F14 during its supported lifetime. Now, it’s heartening to see Fedora 20 back up to the levels of earlier releases — and I note that F21 just crossed up over F20 in use, so we’re off to a great start here, too. Fedora, EPEL, and CentOS ------------------------ At the FOSDEM conference in Brussels, we had a very productive meetup between CentOS project contributors and EPEL and Fedora members, about increased collaboration — making EPEL more official in CentOS, and making it easier for CentOS contributors to join in maintaining packages in EPEL. We also talked about the need for multiple versions of software, and Software Collections (SCLs) as one possible solution (as Tom Callaway noted, Fedora guidelines for these *are* approved by the Fedora Packaging Committee, so it’s no problem to use them in EPEL). I didn’t take notes, but others did, and there should be more on this soon on the epel-devel mailing list. * https://lists.fedoraproject.org/pipermail/epel-devel/ -- Matthew Miller mattdm(a)mattdm.org <http://mattdm.org/> Fedora Project Leader mattdm(a)fedoraproject.org <http://fedoraproject.org/>

fedora 20 to 21
by Patrick Dupre 03 Feb '15

03 Feb '15

Hello, I wish to update a fedora 20 installation to 21 by using a DVD. Is it possible? Actually, I burn a DVD bootable server fedora 21, but I did not find the option update. When I go to installation then System, I can select my hard drive and manually partitioning I can see the installed system (/ /boot and swap) I can install fedora 21 but not on the same partition (I can reuse /boot) I have to install it on a new / I cannot have a mounting point / on the old fedora / This seems to indicate that I cannot upgrade from this DVD. How do you update a fedora 20 without network? Thank. =========================================================================== Patrick DUPRÉ | | email: pdupre(a)gmx.com Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.

So that has to be closed, or wipefs before you can stop the raid and then wipe the raid, i.e. you need to tear it down in the reverse order it was created. You can try this: DOUBLE CHECK DEVICE VALUES wipefs --backup -a /dev/md127 mdadm -S /dev/md127 wipefs --backup -a /dev/sd[cd]1 That will backup the luks signature, then wipe it, stop the array, then backup and wipe the mdadm superblock signature. That ought to fix the problem unless there's also LVM stuff going on here too. The --backup isn't strictly necessary but will write out a file and instructions on how to restore what it wipes in case you get the command wrong and wipe the wrong device. -- Quis custodiet ipsos custodes

kded issue
by Martín Marqués 02 Feb '15

02 Feb '15

Hi all, I have a laptop with Fedora 20 (IIRC I had F19 and upgraded like 6 or 7 months ago to F20) and everything was working great til a few weeks ago. The problem is that every now and then, when I try to sent the laptop to sleep, by closing the top or pressing Fn+F4, it doesn't full finish the sleep process. Let me explain this last thing: It takes some time for the laptop to sleep, and when you open the top and press any key it wakes up but the screen isn't blocked and kded is draining the CPU (I mean kded is hanged). This means that most kde applications won't work (NM won't authenticate, for example) The only way to get back is to kill -9 kded (yes, kill -15 doesn't kill it), and start it again. I'm going to install debugging symbols now so that next time I can gdb on the process. Anyway, has anybody else experienced this? -- Martín Marqués select 'martin.marques' || '@' || 'gmail.com' DBA, Programador, Administrador
