Build rpm - extract source
by arnaud gaboury 27 Oct '16

27 Oct '16

Here is part of my spec file: ----------------------------------------------- Name: mattermost Version: 3.4.0 Release: 1%{?dist} Summary: Mattermost is an open source, self-hosted Slack-alternative URL: http://www.mattermost.org Source0: https://releases.mattermost.com/%{version}/mattermost-%{version}-linux-amd6… License: MIT Group: System Environment/Daemons ........ %prep %autosetup --------------------------- Now testing: $ fedpkg --dist f24 prep leaves me with this error: mattermost-3.4.0: No such file or directory $ ls returns in fact mattermost. I guess the difference is due to untar. How can I tell in my spec file that the source directory will be named %{name} and not %{name}.%{version} ? Then, I though the %autosetup macro would have download the source, which is not the case. I need to run $ spectool -g *spec to get the source. Is it the normal behavior? Thank you for help.

GPG2 can't read smartcard
by Laverne Schrock 26 Oct '16

26 Oct '16

Hi, I have several Fedora 24 boxes, all of which have /home from NFS. Some of these boxes were fresh installs and some are upgrades from 23 (some of which were fresh installs, and some of which were probably upgrades from 22, etc). On the fresh installs, running `gpg2 --card-status` prints out the card info. On the upgraded boxes, running the same command gives gpg: selecting openpgp failed: No such device gpg: OpenPGP card not available: No such device On both boxes, `rpm -qa | grep gnupg | sort` gives gnupg-1.4.21-1.fc24.x86_64 gnupg2-2.1.13-2.fc24.x86_64 gnupg2-smime-2.1.13-2.fc24.x86_64 On both boxes, `rpm -qa | grep pcsc` gives pcsc-lite-1.8.17-2.fc24.x86_64 pcsc-lite-ccid-1.4.23-1.fc24.x86_64 pcsc-lite-libs-1.8.17-2.fc24.x86_64 On both boxes, `ps ax -o user,stat,command | grep scd` gives root Ssl /usr/sbin/pcscd --foreground --auto-exit schr1230 SLl scdaemon --multi-server On the fresh boxes, the pcscd process sometimes dies, but it comes right back when I run `gpg2 --card-status` again. It doesn't seem to die on the old (non-working) boxes. I've checked dmesg and the device is being detected. It is a Yubikey Neo. On the upgraded machines, when I log out after trying this (or even just Ctrl-Alt-F1 to gdm) there is a popup that says Authentication is required to access the smartcard. Administrator Password: <box for pw here> Entering the password has no effect. Any idea on what might be different on these older systems that prevent this from working? Thanks, Laverne Schrock

Off Topic- Architectural Question..
by bruce 26 Oct '16

26 Oct '16

Hey List. This is off topic, but I noticed the list has been quiet!! Trying to get different thoughts on how to approach an issue. I've got a situation, where I'm going to have a shared nfs, with a bunch of files.. I'm going to have multiple client boxes/(vms) with each client, running apps that access the files on the main nfs. The idea, is that a clientApp, on a given clientVM will access a file on the nfs, and then the nfs file is no long used. The goal is to rip through/process the nfs files as fast as possible, in a simple manner. clientVM1 clientApp1 clientVM2 clientApp2 clientVM3 clientApp3 . . clientVMN clientAppN nfsShare dataFiles... The process can't have the same data file operated on by multiple clientApps. I've thought of having a "pid" file on the nfs, where each clientApp would reset/lock/use the pidFile to then get/use/delete the file as required, but this seems tb slow.. but doable. Surprisingly, in looking around, haven't come up with anything that appears to be really better. (I've also thought of setting up a "webservice" kind of situation, where clients would get the "file/data" from a webservice, and the webservice, would interface with the nfs dir.. but this would be overkill!) Any thoughts/comments? Thanks

recommended way to mount a google drive on fedora 24
by Ranjan Maitra 26 Oct '16

Hi, Is there a recommended way to mount a google drive on Fedora 24? I found these instructions online: http://xmodulo.com/mount-google-drive-linux.html (and they involve installing from some place else) but I was wondering if there is something more recent and recommended for Fedora? Many thanks and best wishes, Ranjan -- Important Notice: This mailbox is ignored: e-mails are set to be deleted on receipt. Please respond to the mailing list if appropriate.

Bonjour, I try to find out how to insert a parenthesis in qalculate...: (1+2)*18 And cannot find where are the keys with "(" and ")"... Does anybody know how to do this *very complicated* notation!

F23 rsnapshot log timestamps funny
by Christopher Ross 26 Oct '16

26 Oct '16

Since yesterday's update of rsnapshot to rsnapshot-1.4.2-1.fc23.noarch The format of the date/time field in the rsnapshot.log has gone funny, as per the following examples... [19/Oct/2016:11:53:42] /usr/bin/rsnapshot daily: completed successfully [19/Oct/2016:12:04:15] /usr/bin/rsnapshot hourly: completed successfully [2016-10-19T18:08:11] /usr/bin/rsnapshot hourly: completed successfully [2016-10-20T00:07:09] /usr/bin/rsnapshot hourly: completed successfully [2016-10-20T06:06:31] /usr/bin/rsnapshot hourly: completed successfully Is anyone else seeing this? Is there an easy fix? Many thanks, Chris R.

F24 and general problems (fonts, GNOME extensions...)
by Alex 25 Oct '16

25 Oct '16

Hi, I've just upgraded from fedora23 to fedora24 on my desktop, and the fonts have changed. They now appear to be much smaller by default, and perhaps not as well-defined (anti-aliased?). I don't even know where to start to troubleshoot this issue. I've been using Linux for decades, but haven't followed GNOME and font development. Another issue relates to gnome-tweak-tool and GNOME extensions. When the system is idle for a few minutes, the screensaver is enabled and a password is required to unlock it. I used gnome-tweak-tool in the past to disable this, but it's been enabled again. Many of the extensions are disabled, and visiting extensions.gnome.org with Chrome says "We cannot detect a running copy of GNOME on this system, so some parts of the interface may be disabled," preventing me from installing any extensions or enabling the ones that are currently disabled. When viewing the Appearance section, "Shell theme" is disabled with an exclamation point next to it. What can I do to enable extensions in Chrome again? Thanks, Alex

dev ops --thoughts??
by bruce 25 Oct '16

25 Oct '16

Hi guys. Thanks for your inputs on the fetching/getting of a file from a dir! As Rick pointed out, the ultimate soln will be the use of gearman/rabbitMQ, or some other queueing process, with the clients popping the data off the queue.. I've got a different question/thought as well. Assume I have a VM and i login, and start a process... I can watch (takes a long time).. and see if/when the process dies.. Fix it, restart, etc.. This is doable.. for one VM.. not an issue.. But, if I have 50-100!! My thought is I can create a process/script (whatever) and do a rexec to each of the child clients, fire up the process and they should start to run. However, I'd have no way of logging in to see what the process is actually doing. (I know. There should have been logging to appropriately capture all of this!!) So, I thought, hey, use screen. Screen would allow the ability to rexec into screen, and via Screen, run the targetProcess.. Should work, yes/no? -Although, I can't seem to find pointers on how to chain the rexec/Screen to work. What I'd really like, would be a devOps soln (simple/quick/dirty) to allow me to be able to fire up a bunch of apps across a bunch of VMs, and to periodically have a way to generate a remote "screenshot" of the running process. Thoughts/Comments?? Thanks for any pointers. If I have a vm and I want to "check" on the

Using screen on fedora24
by Alex 24 Oct '16

24 Oct '16

Hi, I've just upgraded from fedora23 to fedora24 on my desktop. For some reason now when I run GNU screen, it no longer sets the hostname in the footer at the bottom of the screen. I typically start screen like this, from a terminal window: [alex@sage ~]$ ssh-agent bash [alex@sage ~]$ ssh-add Enter passphrase for /home/alex/.ssh/id_rsa: Identity added: /home/alex/.ssh/id_rsa (/home/alex/.ssh/id_rsa) Identity added: /home/alex/.ssh/id_dsa (/home/alex/.ssh/id_dsa) [alex@sage ~]$ screen Starting ssh first or just screen without ssh doesn't make a difference. For some reason, the footer I've configured (years ago) no longer displays the hostname and current directory, but instead just "bash". Is someone familiar enough with screen to be able to look at my config and see if the upgrade somehow changed something or has an option that is no longer supported? If you have a ~/.screenrc that you know works with fedora24, I'd love to compare. defscrollback 1000 deflogin on autodetach off startup_message off shell bash activity "active: %n (%t) [%w:%s]" bell "bell: %n (%t) [%w:%s]^G" vbell off nonblock on msgwait 2 termcapinfo * ti@:te@ escape ^Oo bind k bind ^k bind K kill activity 'Activity on screen %n ^G' bindkey ^[0 select 0 bindkey ^[1 select 1 bindkey ^[2 select 2 bindkey ^[3 select 3 bindkey ^[4 select 4 bindkey ^[5 select 5 bindkey ^[6 select 6 bindkey ^[7 select 7 bindkey ^[8 select 8 bindkey ^[9 select 9 bindkey ^[T screen termcapinfo * 'hs:ts=\E]0;:fs=\007:ds=\E]0;\007' defhstatus "screen ^E (^Et) | $USER@^EH" caption always "%{=b dw}%{=b dw}[ %{-b dc}%h%{=b dw} ] [ %= %?%{-b dc}%-Lw%?%{+b dk}(%{+b dw}%n:%t%{+b dk})%?(%u)%?%{-b dw}%?%{-b dc}%+Lw%? %{=b dk}%{=b dw}][%{-b dw} %1`%{=b dw} ]"
