Fwd: Monitor mode (w. TP-Link WN722N & Fedora)
by Fulko Hew 29 Sep '20

29 Sep '20

F.Y.I. I also sent this to the Wireshark user's list to see if someone there can help me. ------ I'm trying to sniff my Wifi for a project, so I purchased a TP-Link WN722N USB adapter and followed the various instructions I've found on the Web. (I don't know if it's a Wireshark issue, a driver issue, or a Fedora issue.) ip link set wlan0 down iw wlan0 set monitor none ip link set wlan0 up When I plugged the adapter in I saw a new device 'wlp0s20f0u3' in addition to my internal adapter 'wlps20'. Using the instructions, it failed: # iw set wlp0s20f0u3 down # iw wlp0s20f0u3 set monitor none command failed: No such device (-19) --> I don't know why? So now that I have 2 adapters, I enabled the TPLink as my network connection (successfully) and tried to put my on-board adapter into monitor mode, instead: # iw wlp2s0 set monitor none # iwconfig wlp2s0 IEEE 802.11 Mode:Monitor Tx-Power=22 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on # iplink set wlp2s0 up # It looks good, so I start Wireshark (v 2.28) (Fedora 26), and look at Wireshark's 'capture options' table, it shows the interface, but under the heading 'Mon Mode', it shows disabled. (I also have 'Use promiscuous mode on all interfaces' enabled.) --> Why does it show disabled? --> Is it really disabled ? --> How do I know which frequencies (or bands) it might be listening on? I started sniffing, but it doesn't capture anything. ... And after about 2 minutes, I get a pop-up error message from Wireshark saying: "The network adapter on which the capture was being done is no longer running; the capture has stopped." Where to start ? Thanks Fulko

Paste into GnuCash problem
by ToddAndMargo 28 Sep '20

28 Sep '20

Hi All, Fedora 32, x64 Xfce 4.14 gnucash-4.1-1.fc32.x86_64 I have a situation where I have the Date, Number, Description, Transfer, Payment, Charge loaded into the secondary clipboard (<ctrl><C>). (Linux has four clipboards.) When I paste (ctrl<V>) into GnuCash, I can't get it to paste across boundaries. In other words everything goes into "date". I have tried tabs and returns as delimiters. (I can insert anything I want if it is on the ascii table.) When typing directly into GnuCash, a tabs moves you to the next category. Anyone know a workaround? Any way to make GnuCash think I am typing and not pasting? Many thanks, -T

Same issue...
by Robert 28 Sep '20

28 Sep '20

Hi I have been experiencing issues with Firefox 80.0.1 on a Lenovo Laptop, which also has a Ryzen processor in it. I have had to resort to using Chrome Browser as it is to unreliable. Not sure this is the appropriate method to respond to the Email I received below but I thought I would give it a try. Robert " I started to get frequent tabs crashes from the moment I recently moved to new laptop. Lenovo E14 Gen 2 with Ryzen 4500U has Firefox tab crash often with the same 16GB which had no problems on oldish Dell Latitude with Intel Gen 6th. cheers, L.

Flatpak - Part 2
by David 28 Sep '20

28 Sep '20

Thank you all, but again, I had to just resolve the issue with my own noggin. [me@localhost ~]$ sudo flatpak update [sudo] password: Looking for updates… Info: org.fedoraproject.Platform is end-of-life, with reason: Fedora 31 runtime is no longer supported. Nothing to do. [me@localhost ~]$ flatpak remove org.fedoraproject.Platform Similar installed refs found for ‘org.fedoraproject.Platform’: 1) runtime/org.fedoraproject.Platform/x86_64/f31 (system) 2) runtime/org.fedoraproject.Platform/x86_64/f32 (system) 3) All of the above Which do you want to use (0 to abort)? [0-3]: 1 ID Branch Op 1. [-] org.fedoraproject.Platform f31 r Uninstall complete. [me@localhost ~]$ Again, the point was, that new users to Linux are not going to ph*ck with all that flatpak nonsense. But I will keep using flatpaks and appimages in Rawhide, because I am a glutton for punishment, and want lots of attention. LOL ! My plan as stated before, is simply to show people who have never used Fedora or Rawhide, how to get started, the pro & cons, the pitfalls, and most of all that you will be almost entirely on your own, and explain all that using newbie-language, street-talk, slang, vulgarities, comedy, metaphors, puns, etc. But I do love you all. Don't get me wrong. David Locklear

flatpak question
by David 28 Sep '20

28 Sep '20

I get a message when trying to update flatpak $ flatpak update Looking for updates… Info: org.fedoraproject.Platform is end-of-life, with reason: Fedora 31 runtime is no longer supported. Nothing to do. $ I do not think a novice user of Linux is going to find it simple to use flatpaks. The runtime thing is still way over my head, and all the different hubs ( two ? ), and how to know which hub is better, flathub or Fedorahub. ( I hear somebody out there joking..... P***hub, silly ) While I have your attention, I spent about 5 hours playing with appimages, and posted something about that here a few days ago. I have not yet dived deep into the topic, but my initial experience is that appimages are not for newbies, in their present form. It was suggested to me to discuss such things elsewhere on the community blog. I attempted that, but it has been 3 days now, and my post there is still pending. Another similar post I made in the other suggested Fedora forum, did not reach my intended audience. So I will have to think of some other way to express my ideas or rants. Once I feel confident, in the topic I want to discuss, maybe I will make a YouTube video. I am not there yet. Today's update of Rawhide, went smoothly. A tiny change to the kernel. It is worth noting, that since the kernel is allegedly hovering around 27.8 million lines of code, that if one line gets changed, the user is probably not going to notice much difference, unless that particular thing was something they were hoping would improve. Much of the changes appear geared toward future hardware that has not even hit the market yet. Meaning, one of many reasons a novice Linux user should not use Rawhide, is that the changes that might break their system are unlikely to give them any kind of noticeable improvement in their own user experience. Some other updates today were that packages like dracut and criu were rebuilt from fc33 to fc34. Many packages at this early stage in fc34 development, are going to be identical to what is in the upcoming beta release of Fedora 33, for example, the package or client "gnumeric," is still fc33. I do not know yet what those package differences are or what all that entails, but it is on my list of things to learn. My current vague grasp of the topic is that the package is compiled ( or recompiled ? ), with a newer version of the newer version of the tools that are used to build the packages for fc34. One important characteric of Rawhide is that many of the most important system components are git-versions of that package, and the git-version was only updated from one that might have been a few days stale. A novice would never have any idea what any of that means, but I am trying to self-teach myself. And on a similar note, many important system files are "rc candidates" such as mesa and the kernel. I assume many other packages are identical to what is going to be in Fedora 33 Beta. For example, x.org files and at least half the dependencies or files that other packages require to run, are still fc33, at this early stage in fc34 history. All that is just my own observation, and irrelevant. I am just trying to learn the correct way to express things about Fedora and Rawhide. Another reason to discourage a novice from using Rawhide, is that much of the files that are often updated are files related to writing software or programming such as python, perl, rust, etc. Most people do not need the newer versions of those packages. I do plan to do an install of Fedora 33 on hardware in December, and live in that for a while. But I have not yet had a reason for myself to stop using Rawhide. One of the reasons that I stopped distro-hopping a year ago, is that the only thing I would gain from using some other distro like SparkyLinux, LInux Mint, Netrunner, or PopOS!, is just to see how those other distros modify or customize the theming of their packages, some of which seem to only just get renamed ( or rebadged ?? ) in those other lesser distros. And I always use my own wallpapers, so the tiny one-man distros that mainly just have fancy wallpapers, probably are not my cup of tea. On a related note, I will probably never try Cucumber Linux: https://cucumberlinux.com/about.php Good Day from Arcola, Texas USA. David Locklear novice user of Rawhide

Just another thought: I observed (totally different conditions), that the system became sluggish beyond usable. In most of those cases it was a lame dns-server that was to blame: active, but not resolving. From: "Roger Heflin" <rogerheflin(a)gmail.com<mailto:rogerheflin@gmail.com>> Date: Sunday, 27 September 2020 at 13:41:32 To: "Community support for Fedora users" <users(a)lists.fedoraproject.org<mailto:users@lists.fedoraproject.org>> Cc: "ToddAndMargo" <ToddAndMargo(a)zoho.com<mailto:ToddAndMargo@zoho.com>> Subject: Re: Reload kernel? From the vmstat, all of the time is idle, you do not have any wait, generally if you have a disk having issues the iowait will go up, but you have zero. Also from vmstat, the system time is low. So the gui gets slow, a reboot clears it, does it clear up? You might want to include a messages file from +=5 minutes of the the issue happening. Weird kernel bugs causing kernel lock issues would produce this behavior, and would don't usually show on vmstat, but they can be seen in the messages file.
