diff or deduplicate two volumes with different folder structures
by Chris Murphy 22 Sep '16

22 Sep '16

Drives A and B have many overlapping files but I want to find out what files don't exist on each. Thwarting this is directory structure differs between the two drives, and I'm fairly certain some of the file names differ on the two drives also. Therefore I need something hash based. I started with this: $ find /brickA -type f -exec md5sum "{}" + > brickA.txt $ find /brickB -type f -exec md5sum "{}" + > brickB.txt What I need next is to: Make a copy of the files, brickAcopy.txt and brickBcopy.txt Loop: Extract each md5sum in brickA.txt, grep for it in brickAcopy.txt and brickBcopy.txt, and if it's found in both, delete the line in both files. What remains in each file are paths to files that don't exist on the other drive. This must be a solved problem, so I'm open to alternative approaches. Both drives use Btrfs, I can create snapshots and perform a "dedup" operation on those snapshots directly. Ideally the dedup would delete the files in both snapshots (i.e. it'd be considered data loss if it weren't for the snapshots) just to save time. But if necessary I'll just do a one way dedup with the two operations reversed and suffer the extra processing time. Ideas? -- Chris Murphy

build xorg-x11-drv-libinput-0.19.1-1.fc24 ?
by Konstantin Svist 22 Sep '16

22 Sep '16

Hi, The touchpad driver handling has been switched over from synaptics to libinput recently (libinput 1.5.0), but the libinput xorg driver is a bit behind -- it doesn't provide an option to swap tap-to-click buttons. There are test builds for fc25 and fc26 (see http://koji.fedoraproject.org/koji/packageinfo?packageID=18894) but nothing for fc24... Who can I ask to build this in Koji?

screen question?
by bruce 22 Sep '16

22 Sep '16

Hey guys. Trying to get my heads around something. I'm looking to automate a process. Basically, I want to kick off/initiate a number of processes on remote boxes. I've looked at different online sites, but I'm missing something.. I can ssh into the box, trivial. I know I can create a "screen" process, that allows me to then later access the 'screen' session to see the progress of the action. And of course I can access the screen and fire up my process. However, (and here's where I'm not getting how to do it) - I'd like to be able to auto/programatically : ssh into the remote box create the screen session (with a name I define) access the screen session, and then fire up/start my process If I can figure out how to do all of this initially for a test, I can of course roll out the rest of my tests... Hope this makes sense. (if someone has a chunk of code, or pointers to any code I can look at, that would be great.) I suspect this is really trivial. Thanks again...

Anacron mail -
by Bob Goodwin 21 Sep '16

21 Sep '16

I have been using Linux for a long time and have yet to see a cron/anacron mail message. In [root@Box10 bobg]# cat /etc/aliases I configured: # Person who should get root's mail root: bobg And after a bit of googling I dnf installed mail. Mail is difficult to use, has a long list of commands, but it did display about five hundred messages of which it displays several pages and stops, those are old from a couple of months ago while today's messages are all I am interested at the moment. Is there a command to display only what I want, a specific day or perhaps reverse the order so that today's messages are at the top, display first? Better yet I would think would be to display them in Thunderbird but I don't know how to do that ... Any help appreciated, Bob -- Bob Goodwin - Zuni, Virginia, USA http://www.qrz.com/db/W2BOD box10 FEDORA-24/64bit LINUX XFCE POP3

Alpine question
by William Oliver 20 Sep '16

20 Sep '16

I don't know if this is a fedora question or not, but I'm hoping it's an OS-level config issue. I have a laptop that runs Fedora 24, and a virtual machine with CentOS that I use as my mailserver. I'm an old fogey who doesn't like all this multimedia mail stuff, so I still use pine/alpine and text emails. The problem is this. When I ssh to my virtual machine from my laptop and run pine, it will work for a few minutes and then hang. If I close the terminal (which kills pine) and ssh in again, it works again -- for a few minutes. Then it hangs. I don't *think* it's a pine/alpine issue itself. If I come in using shellinabox and open pine using a browser terminal, it doesn't happen. If I use some other client, e.g. roundcube, it doesn't happen. If I just ssh in and do other stuff, it doesn't hang. Finally, it only happens at work. My workplace has a very restricted wired network and a very open wireless network. We are supposed to "work" on the wired network and attach our cellphones and private laptops to the wireless network, which solves a lot of social engineering type security issues. If you want to do streaming media, or download cute stuff, don't use the work box -- use your own. So, the problem occurs on this wireless system. It doesn't seem to happen when I connect from my wireless at home. Any pointers? It's very frustrating... billo

anacron/cron
by Patrick Dupre 19 Sep '16

19 Sep '16

Hello, In my mailbox, I receive emails: Anacron job 'cron.weekly' on While I do not receive any amail: Anacron job 'cron.daily' on while it should run daily: logrotate certwatch It even more strange, on a fc22 machine I had Anacron job 'cron.daily' on until July 14. and then not anymore ! Is anacrontab controlled by /etc/crontab or by /etc/anacrontab ? In addition, in fc22 I had: /etc/cron.daily/mlocate while in fc24, I do not have such a file. How mlocate is now managed ?

orca broken after updates
by Gordon Messmer 19 Sep '16

19 Sep '16

After this morning's updates, I noticed that a bunch of common keyboard shortcuts didn't work. In gnome-terminal, shift-insert didn't paste selected text. In thunderbird, 'b' wouldn't move to the previous message in the folder, but only if the keyboard focus was in the message body pane. In firefox, the up and down arrow keys moved between links rather than scrolling the page up and down. I tried dnf history rollback, but a number of the previous package versions aren't available, to that failed. Grump: there's no point in having "history rollback" if packages don't remain available in the updates tree long enough to roll back to when there are problems. Then I tried gathering the names of updated packages and using "dnf downgrade" instead. That caused dnf to offer to install dozens of i686 packages that are not currently installed. I tracked that to evolution-data-server. Why downgrading that tries to install i686 packages is unfathomable. Excluding that, the downgrade didn't resolve the problem, but at that point I noticed that the "orca" process was using a whole lot of CPU time. I killed it, and at that point keyboard shortcuts were restored. My guess is that this is related to the python3 package upgrades somehow, but downgrading them didn't fix the problem. I'm going to try to find time later to resume troubleshooting this, unless someone beats me to it. In the mean time: if you're having problems with keyboard input after updating, killing the "orca" process will work around the problem until the root cause has been found and fixed.
