How to define a variable in .def file in Linux Posted: 29 Nov 2021 07:50 AM PST I am working first time on def file in Linux, but don't know how to set a variable in def file. i tried by below ways, but it's not working for me. **Test_DIR=/usr/include/ TEST_DIR_GCC_VERSION=$(shell gcc -dumpversion) #define TEST_LIB $(Test_DIR)/$(TEST_DIR_GCC_VERSION)** in result i am getting only TEST_LIB=/usr/include,but not getting the entire variable path. Any help will really appreciated, as struggling from last three days.

Linux clipboard on Windows Posted: 29 Nov 2021 05:53 AM PST Is there somewhere a software to get the select/middle-click clipboard of Linux, on Windows? (without losing the capacity to close a tab with a middle-click, without having focus on mouse, without having to focus a window to paste, with capacity to select on double-click)

Dolphin crashes on opening terminal Posted: 29 Nov 2021 07:25 AM PST I'm using Dolphin(FM) on a daily basis. And, it crashes while opening a terminal window on current working directory. Same result by using the shortcut Shift + F4. But, it works if I open it as panel... Currently I'm using Manjaro: Qonos, 21.2.0 on KDE Plasma Version: 5.23.3 KDE Frameworks Version: 5.88.0 Qt Version: 5.15.2 Kernel Version: 5.10.79-1-MANJARO (64-bit) Graphics Platform: X11 Graphics Processor: AMD ARUBA So, do I consider it as a bug?

How to access files in USB in linux Posted: 29 Nov 2021 07:27 AM PST I'm using Ubuntu 20.04, recently (almost a week ago) I upgraded my kernel from 5.11.0 to 5.14.0 and after that I can't access any USB drivers. The system recognises my USBs since when I run lsusb it give the output Bus 001 Device 005: ID 0781:556b SanDisk Corp. Cruzer Edge And even dmesg gives [16972.246970] usb 1-2: new high-speed USB device number 5 using xhci_hcd [16972.395933] usb 1-2: New USB device found, idVendor=0781, idProduct=556b, bcdDevice= 1.26 [16972.395938] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [16972.395939] usb 1-2: Product: Cruzer Edge [16972.395940] usb 1-2: Manufacturer: SanDisk [16972.395941] usb 1-2: SerialNumber: 2005375352115C834970 But lsblk does show the device mounted anywhere this is the output of lsblk, in this both sda and sdb are harddrives sda 8:0 0 931.5G 0 disk ├─sda1 8:1 0 16M 0 part └─sda2 8:2 0 931.5G 0 part sdb 8:16 0 119.2G 0 disk ├─sdb1 8:17 0 260M 0 part /boot/efi ├─sdb2 8:18 0 16M 0 part ├─sdb3 8:19 0 80.7G 0 part ├─sdb4 8:20 0 37.3G 0 part / └─sdb5 8:21 0 980M 0 part The USB isn't faulty because I've checked it in other laptops neither is the USB port since I've tested it in windows (I've dual booted Ubuntu with windows) in the same machine and it works well there. I doubt that this might have happened because, while generating config files for modules and driver while upgrading to kernel 5.14.0 I used make localmodconfig which makes a new config file from the drivers in use at that time instead of copying the config files in the old kernel, therefore maybe the device driver maybe missing (not sure though, I don't know much about accessing block devices). If that's the case how to fix it? Is there any way I can find the device and mount it into a directory to access the files in a USB?

"sshpass" with "scp" just hangs (Failed publickey) Posted: 29 Nov 2021 04:15 AM PST I am trying to send folder from my Linux machine. This command works entirely and my folder is transferred if I run it manually from my Linux server. sshpass -vvv -f /home/user1/sshpass.txt -P assphrase scp -o StrictHostKeyChecking=no -r dir1 user1@10.7.175.143:/ On the server side I can see that public key was Accepted. Accepted publickey for user1 from 10.7.141.243 port 37960 ssh2: RSA SHA256:.... Now I put the same command in the Jenkins build commands. Build is executed of course on the same RHEL server. sh "pwd" sh "sshpass -vvv -f /home/user1/sshpass.txt -P assphrase scp -o StrictHostKeyChecking=no -r dir1 user1@10.7.175.143:/" Output on the client side: sshpass -vvv -f /home/user1/sshpass.txt -P assphrase scp -o StrictHostKeyChecking=no -r tools user1@10.7.175.143:/ SSHPASS searching for password prompt using match "assphrase" SSHPASS read: user1@10.7.175.143's password: This output just hangs and nothing happens until I Abort the execution. I have run the server in debug mode and I can notice one Error in this case: Failed publickey for user1 from 10.7.141.243 port 38922 ssh2: RSA SHA256:d+34+L7wemb.... But the same public key is being used for my manual sshpass execution. Can you please assist me what might be the issue of this strange behaviour? Thank you!

Using shell builtins command over ssh [closed] Posted: 29 Nov 2021 04:40 AM PST The following command doesn't give an output. sshpass -f ~/.password.txt ssh <user>@<ip> "which ls" I found out that which is a builtin command so I also tried with sshpass -f ~/.password.txt ssh <user>@<ip> "/bin/which ls" This gives me no results as well. I've also tried to run this command with bash -l. sshpass -f ~/.password.txt ssh <user>@<ip> 'bash -l "which ls"' How can I use the which command in an SSH connection?

How to toggle fullscreen on any app in Xmonad WM? Posted: 29 Nov 2021 07:08 AM PST I'm new around Xmonad WM and haskell is completely new to me, so be patient. Running the almost stock ArcoLinux Xmonad. I'm trying to setup my browser i.e Brave to be able to go full screen at anytime I want and bind that to (modMask, xK_f) - Basically use that binding as a toggle to go full screen in some of the apps that I need, especially the browser. while hiding the polybar completely. The second thing I don't find how to do is to get rid completely of transparency in Xmonad. I don't like it and I'd love to get rid of it completely.

How can I use xmlstarlet to query a tag for two attribute values? Posted: 29 Nov 2021 07:29 AM PST Example:- <item href="cover.jpeg" id="cover" media-type="image/jpeg"/> I'd like to select @id="cover" and media-type="image/*" and retrieve @href. My current "solution" seems to be:- xmlstarlet sel -t -m "//_:item[@id='$opf_cover_name']" -v @href -o '|' -v @media-type -n file.xml, followed by some extremely messy splitting around the '|' character of the output. Does xmlstarlet have a substring function? Version = 1.6.1 compiled against libxml2 2.9.4, linked with 20904 compiled against libxslt 1.1.29, linked with 10132

Awk/sed to separate last column and add quotes around middle column? Posted: 29 Nov 2021 06:54 AM PST I've got a file called test.txt and after some manipulations it looks like this: Metabolism Global and overview maps 01100 Metabolic pathways (1689) 01110 Biosynthesis of secondary metabolites (677) 01120 Microbial metabolism in diverse environments (356) 01200 Carbon metabolism (44) 012111 Carbon metabolism (151) test: test test (44) Now, I want to separate the last column with bracketed numbers so that they are a separate column (using semi colons as my delimiter of choice). I also want to put quotes around all text that are between the bracketed numbers and the ID numbers at the start. Finally, I would like to keep the header rows (the first two in this example). My code: sed -r 's/ +/;/' test.txt | awk 'NF{NF-=1};1' | awk -F ";" '{sub($2, "\"&\""); print}' My current output: "" Global;"and overview" 01100;"Metabolic pathways" 01110;"Biosynthesis of secondary metabolites" 01120;"Microbial metabolism in diverse environments" 01200;"Carbon metabolism" 012111;Carbon (151) test: test test As you can see the "Metabolism" header is gone because it is technically the last value in that row, as well as "maps" in the second row, with a semi colon after "Global" which is not needed. Some rows have bracketed numbers within the text which I should keep but otherwise all rows end with a bracketed value that should be separated into it's only column separated by a semi colon. I also can't get the quotes to go around all of the second column in the last row, whereas the other rows are okay. Finally, I don't know how to separate the bracketed values so that they are a third column. My desired output (keeping the numbers as a sep column): "Metabolism" "Global and overview" 01100:"Metabolic pathways";1689 01110:"Biosynthesis of secondary metabolites";677 01120:"Microbial metabolism in diverse environments";356 01200:"Carbon metabolism";44 012111:"Carbon metabolism (151) test: test test";44 using awk GNU version 4.1.3 and sed GNU version 4.2.2. on Windows Linux Sub-system

How to connect Ubuntu to AirPlay speakers placed in another network? Posted: 29 Nov 2021 04:45 AM PST I have Ubuntu 21.10 with ip 192.168.0.1 connected to a router having a static ip WAN=192.168.0.2 and Gateway=192.168.0.1; basically my Ubuntu is the Gateway. The router's LAN address is 192.168.1.1. In LAN I have some KEF SLX WIFI speakers to which I can connect from my iPhone and Windows 10 computer, both in router's LAN. I also want to connect to the speakers from my Ubuntu (192.168.0.1) too; how should I configure the router (or Ubuntu) to have it? I already enabled Make discoverable Apple AirTunes sound devices available locally in paprefs (used sudo ln -sv '/usr/lib/pulse-15.0+dfsg1' /usr/lib/pulse-15.0) but locally means 192.168.0.0/24 for Ubuntu. In the end Ubuntu machine must remain the Gateway for the router.

coverswitch, flip-switch is missing from TaskSwitcher Posted: 29 Nov 2021 07:28 AM PST Everything was working fine. I update my PC last night & found out that task switching defaults to breeze scheme. Though, I don't use other effects available there rather than flip-switch(as alternative) and cover-switch. Both, seems to be rolled out. Is there a way to get them back?? Though, I'm not sure if it happens to everyone who uses kde. I'm on KDE (Plasma: 5.23.3, Framework: 5.88.0, Qt: 5.15.2) over Manjaro.

Windows cannot access Samba after changing password Posted: 29 Nov 2021 04:17 AM PST I have a samba server setup in Ubuntu 18.04 and have multiple users with their own respective folder to access with their credentials. Right after a user changes his/her samba password the users cannot log into the samba share without restarting the computer or clearing out the cache. Can it be configured from somewhere in the samba server that the user credentials are not cached in the Windows machines?

Bluetooth Mouse Lag Posted: 29 Nov 2021 07:56 AM PST looking for help diagnosing bluetooth mouse lag. I'm using a Logitech MX Anywhere 2, I've had it a few years now and it's worked well on a number of Linux distros. I recently installed Debian 10 and set it up to use Sid repos. In this environment, the mouse does not work as responsively as normal. I'm on a laptop, and the touchpad works perfectly smoothly, and a wired mouse is also perfectly smooth. What I get with the bluetooth mouse is as if the sampling rate is maybe once every 3 or 4 frames. I still have Pop!_OS installed which is based on Ubuntu 19.04, the mouse works as expected in that environment. Forgetting the mouse and re-adding it offers no change to behaviour, same with reboots. I've updated to the latest state of the repos, no dice. I've also tried switching from Wayland to Xorg with no effect. My best guess would be that it's down to the iwlwifi module (it's a Lenovo Yoga 900 with an Intel Core i7 6560U with integrated Intel Wireless 8260), but no idea where to go from here. Cheers!

Detect CLI or Wine executable in Manjaro Posted: 29 Nov 2021 04:50 AM PST In my Linux Mint installation, I can directly execute a PE executable at the command line, and if it's a .NET/CLI executable, then it will automatically execute it with Mono, and otherwise, it will automatically execute it with Wine. This works because binfmt is configured to run /usr/lib/binfmt-support/run-detectors for both CLI and Wine executables. This runs a series of detectors configured in /var/lib/binfmts to determine what type of PE executable it is and execute the appropriate command to run it. In Manjaro, I have binfmt, but I don't have run-detectors. So I guess the first match in /proc/sys/fs/binfmt_misc wins, and I guess since I installed Wine before I installed Mono, that's the one that wins. That my supposition, anyway. The symptom is that whenever I execute an .exe file from the command line, it runs Wine, even if it's a .NET executable. I can't find a package that seems to supply this run-detectors utility. Is there something like it in the standard or community repositories, or is there some other common way to set this up in the Arch world?

Black Screen Boot & Freezing Boot Posted: 29 Nov 2021 07:02 AM PST So I'm working on a friend's computer to install Linux Mint 18.2 onto it since his Windows broke after the Creator Update. He wasn't able to install it himself for some reason, however when I first tried the Live USB on the system, it booted right into the Live USB and I was able to complete an install to his SSD. After the install, we attempted to reboot into the installed partition, however it goes to the GRUB menu, and once we select the installation for Linux Mint it just goes to a black screen with nothing on it, we've waited over 10 minutes with no changes to the screen. We then tried the Live USB again, multiple times and gives us the same thing as booting into the partition, a blinking underscore in the corner for a second and then just a black screen, then the screen goes to sleep. Systems specs are an FX-8350 and a Radeon R9 280X, no onboard video What have we tried? We've tried changing the boot parameters to have nomodeset xforcevesa instead of "quiet splash", this works about 10% of the time to get it to boot into Mint from the installed partition. The other 80% it goes to the command line output for booting into everything and reaches Switching to clocksource: tsc (or something similar) and then just freezes and doesn't go anywhere. The other 10% it just hangs in the middle of boot sequence. If we keep quiet splash and put in the nomodeset xforcevesa we receive an ERROR no UMS support in radeon module We also tried just a nomodeset, this doesn't seem to have much affect, maybe 1 % or less of the time it loads into the OS. We tried a live USB of Ubuntu 16.04 LTS, I have not been able to boot into it at all, even with the various parameter changes. We've tried using noacpi and nolacpi and acpi options in the Ubuntu Live USB to no avail, gives us I believe the ERROR No UMS Support in radeon module errors. We've tried a live USB of Linux Mint 17.3 since we've discovered that AMD drivers for 18.2 aren't supported until AMD rewrites everything I guess? Didn't make sense to me, but that's what we read on the forums. Was unable to get 17.3 to boot at all, even with parameter changes.

How do you use proxy with the whois command? Posted: 29 Nov 2021 05:25 AM PST I tried exporting into http_proxy and https_proxy but that didn't seem to work. I am guessing that there is another way to use a proxy when querying whois information from the command line?

VNC - Too many authentication failures Posted: 29 Nov 2021 06:04 AM PST I've been trying to Google, but all of the issues refers connection from PC to remote VNC server. So. I have an issue with VNC communication from Android to Linux. I have installed a TightVNC Server on latest Ubuntu version which works fine if I connect to it from PC with RealVNC Viewer on port 5901. I downloaded a VNC Viewer by RealVNC for Android and if I try to connect to my remote host it says "Too many authentication failures" even on first try. I also tried a couple different VNC Viewers, but result is exactly same. What would be the reason and how I am able to fix it? Some people were speaking about that the client can be unsecure, but I'm not sure what difference there would be with PC and Android version of VNC. From PC to remote: Works From Android to remote: Doesn't work About half-year ago on my different server I had no similar issues. It was working fine, no matter what device I used to connect VNC if I knew IP, port and password.

linux/shell command to control screen brightness in android Posted: 29 Nov 2021 04:03 AM PST I am working on a kiosk project using an android tablet.If there is no input power to the kiosk for a long time then, the tablet will eventually shutdown.In order to auto-reboot the tab when the power comes back I modified the code in my tabs battery animation file(ipod) using: #!/system/bin/sh sleep 300 /system/bin/reboot However,during the sleep period(shown above),the tabs screen remains in the ON state (and hence takes longer retries for the tab to charge and bootup).I need to turn the screen OFF. What is the command I should use prior to the sleep command to turn my tabs screen OFF during the charging/bootup stage. Thanks !

How can you change ident, which shows up as ident@hostname.com on ircll? Posted: 29 Nov 2021 05:28 AM PST I know the nickname and the real name field can be changed with environment variables such as IRCNICK and IRCNAME. However, the documentation does not tell you how the ident is changed. (The ident is the name that's used when you /whois nickname, and it shows up as part of ident@username.com in the host field, and the bolded part is what I'm trying to figure out how to change) I'm wondering if this is possible on the ircll client.
