Can't change Qt version from 5.12.8 to 5.15.X Posted: 15 Jul 2021 10:48 AM PDT I've tried building packages from qt's website but everytime I try to cmake a specific file that requests qt version 5.15 I'm always told it fails because I'm using the default version 5.12.8. How can I make it so I'm using a new version of qt? APT packages don't seem to solve the issue. I'm attempting to cmake some libs from the kde api repo because I can't find them on my computer and this issue is preventing that. I would like to finish building that kdeconnect app via vscode.

ldd shows libstdc++ not found but for clang its available, how is this possible? Posted: 15 Jul 2021 10:55 AM PDT I run fedora 34, how is this possible (ldd shows libstdc++ not found but for clang its available):

Output of 2 commands get the difference (ls vs du) Posted: 15 Jul 2021 09:59 AM PDT So analyzing an issue at work I found that, when I created some datafiles on Oracle, the datafiles didn't reserve the space in the Filesystem, so I went to the sapdata filesystem where I put the datafiles and for my surprise an ls -ltr show the file with the specified weight when I created the datafile, but a du -gs say it was 0.00 so to compare I made this two commands: A) find ./sapdata* -name "temp*" -type f -exec du -gs {} \; B) find ./sapdata* -name "temp*" -type f -exec ls -ltr {} \; | awk '{printf ("%.2f\t%s\n", $5/1024/1024/1024,$9)}' The last one result on an output that is equal to the output of the first one, but the second one using the information from ls -ltr. In practice it's everything ok, I manage to see the difference and we are looking at the issue, but I want to go a step forward in two ways: 1.- Mix both results into something that tells me which files are different in one line 2.- Mix both results and get a "Health status" of the comparisons, this would be useful to make a monitoring script. The output I get from this commands are the following for an example A) Gives me: 15.63 ./sapdata19/temp_1/temp.data1 25.31 ./sapdata20/temp_2/temp.data2 B) Gives me: 15.63 ./sapdata19/temp_1/temp.data1 0.00 ./sapdata20/temp_2/temp.data2 So from solution 1 I would want something like DU DIFF LS -------------------------------------------------------- ---------- -------------------------------------------------------- 15.63 ./sapdata19/temp_1/temp.data1 OK 15.63 ./sapdata19/temp_1/temp.data1 25.31 ./sapdata20/temp_2/temp.data2 FAILED 0.00 ./sapdata20/temp_2/temp.data2 Or something similar, the headers are not needed although I know it's possible For solution 2 I would want something like Health=50% Number of Failed=1 Total Number of Datafiles=2 List of Failed= ./sapdata20/temp_2/temp.data2 Maybe the last solution I can do it without much issues with a Bash script, but the first one since I want it in one line I'm not sure how to do it. I guess with xargs and diff or maybe a for inside awk but I'm not sure. Regards!

Keyboard and trackpad problems in Opensuse Tumbleweed 15 Posted: 15 Jul 2021 09:41 AM PDT Recently I installed OpenSuse tumbleweed 15 on my 2015 MacBook 8,1 retina model, and both the keyboard and trackpad are not working (only externally connected ones). I'm not that experienced with these configurations, so any help would be appreciated. I saw a fix for a similar situation on Ubuntu, but said fix would not work on OpenSuse.

Ubuntu 20.04 not detecting external monitor anymore Posted: 15 Jul 2021 08:40 AM PDT It would be great if someone can help me. I was using the two external monitors plugged into ThinkPad-T14s-Gen-1 that has installed only Ubuntu 20.04, the laptop has AMD Ryzen 7 pro 4750u with AMD integrated graphics. One monitor was plugged into HDMI and other one into USB C socket, the laptop has two USB C sockets, one can be used both for charging and display, other one only for data. Everything was working fine but, both of monitors were detected but after some updates, after I did some updates(apt get update and upgrade) from 20.04 to 20.04.1 and 20.04.02, one day it suddenly is not detecting the one monitor plugged into USB C socket, its not even working after unplugging and plugging it back in(before it would work if I unplug and plug it back) The cable USB is good, its new and I have bought another one USB to check but they both dont work so its not about cables, it must be software issue. However I suspect the reason why the monitor stopped responding is because once I had accidentally clicked suspend option when I wanted to shutdown the pc. When I logged back in one monitor was not detected anymore. I am sharing my output of xrandr on terminal, btw I am absolute beginner to Linux. I have unplugged the monitor from HDMI, since its working but I plugged in the other one into USB C but its not detecting, its only detecting the laptop display(eDP): Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384 eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 173mm 1920x1080 60.00*+ 1680x1050 60.00 1280x1024 60.00 1440x900 60.00 1280x800 60.00 1280x720 60.00 1024x768 60.00 800x600 60.00 640x480 60.00 HDMI-A-0 disconnected (normal left inverted right x axis y axis) DisplayPort-0 disconnected (normal left inverted right x axis y axis) DisplayPort-1 disconnected (normal left inverted right x axis y axis)

How to create custom keyboard shortcuts in Gnome with wayland? Posted: 15 Jul 2021 08:29 AM PDT My main target: bind Alt+Arrow Left/Right as Home/End buttons.

I have a result from editing stream as follows using sed command: filename_1 filename_2 . . filename_n Now depending upon the number of files in the previous result I want to execute the command in shell as follows. some_command --foo "filname_1" --foo "filename_2" --foo "filename_n" remaining_some_command Where --foo is flag in between the command and filename_1...filename_n are its values depending on the result from sed . It should be possible in shell. But how?

Set console resolution on armbian buster / NanoPI M4 Posted: 15 Jul 2021 08:25 AM PDT I have a NanoPI M4 hooked up to a Uniroi 1024x600px HDMI screen running Armbian Buster 5.10.43-rockchip64 booting to a console (no X).

UTF-8 characters are not printed correctly on the console Posted: 15 Jul 2021 09:16 AM PDT I've seen some questions similar to this one but I'm not being able to use the solutions of those to help me.

Is there a comprehensive list of all the ways to view a file's contents in linux?

How can I identify what process is sending emails? Posted: 15 Jul 2021 08:39 AM PDT My email service provider has informed me that I keep hitting my daily SMTP quota limit and has identified one of my servers as sending email from a root account. I've disabled any cronjobs that were sending emails and then checked my mail logs and syslog and can see the mail process they're referring to is still running each minute. However, it's not running from the cron, and appears to be a standalone SMTP process. tail -f ./var/log/syslog Jul 15 09:25:02 serveralias sSMTP[1359056]: Creating SSL connection to host Jul 15 09:25:03 serveralias sSMTP[1359056]: SSL connection using ECDHE_RSA_AES_256_GCM_SHA384 Jul 15 09:25:06 serveralias sSMTP[1359056]: Sent mail for root@serveralias.com (221 2.0.0 Bye) uid=1000 username=not-root-account outbytes=1332 Jul 15 09:26:01 serveralias sSMTP[1359129]: Creating SSL connection to host Jul 15 09:26:03 serveralias sSMTP[1359129]: SSL connection using ECDHE_RSA_AES_256_GCM_SHA384 Jul 15 09:26:05 serveralias sSMTP[1359129]: Sent mail for root@serveralias.com (221 2.0.0 Bye) uid=1000 username=not-root-account outbytes=1332 Is there a way I can identify this process and see what it's doing?

how to use quantifiers in sed substitution expression? Posted: 15 Jul 2021 09:13 AM PDT I'm using | sed to indent the result of some command (let's take a plain $ echo something for this example). I want to prefix the result with say 10 spaces. The following works fine : $ echo something | sed 's/^/ /g' something But isn't there a way to use quantifiers in the | sed expression ? I tried for example $ echo something | sed 's/^/ {10}/g' {10}something but obviously it doesn't work, {10} isn't interpreted as a quantifier. And protecting the braces with backslashes doesn't work either : $ echo something | sed 's/^/ \{10\}/g' {10}something Is there a way to use quantifiers in the substitution expression ?

IP forwarding, masquareding, NAT Posted: 15 Jul 2021 09:36 AM PDT I have one physical interface eth0 on my target, running Linux. The IP address of this interface is 172.16.81.x (public IP). I have to create a virtual interface eth0:1 with IP address 173.1.1.x. I will be running socket server with custom port 49155 using IP address 173.1.1.x. From another PC/target I should not be able to ping 173.1.1.x. However, from another PC I will be running a socket client program. This client should be able to connect to port 49155 on the 172.16.81.x public IP. I have tried NAT, bridge but not successful. with below iptable rules, was able to establish server<-->client communication: echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward sudo iptables -A FORWARD -i ens33 -o 173.1.1.6 -p tcp --syn --dport 49155 -m conntrack --ctstate NEW -j ACCEPT sudo iptables -A FORWARD -i ens33 -o 173.1.1.6 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -A FORWARD -i ens33 -o 173.1.1.6 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -t nat -A PREROUTING -i ens33 -p tcp --dport 49155 -j DNAT --to-destination 173.1.1.6 sudo iptables -t nat -A POSTROUTING -o ens33 -p tcp --dport 49155 -d 173.1.1.6 -j SNAT --to-source 192.168.233.251 sudo iptables -A INPUT -m tcp -p tcp -s 192.168.233.251 --dport 49155 -j ACCEPT at this point still 173.1.1.6 is pingable from outside PC. however i have to also make 173.1.1.6 invisible for external world for that i add below rules: sudo iptables -A INPUT -d 173.1.1.6 -j DROP sudo iptables -A OUTPUT -s 173.1.1.6 -j DROP sudo iptables -A FORWARD -s 173.1.1.6 -j DROP after this ping is blocked. server <--> client communication also doesnt happen.

How to temporarily hide an icon on XFce4's panel? Posted: 15 Jul 2021 08:25 AM PDT I have an icon on the panel that I'd like to hide, but only temporarily, i.e. my mail check icon. There are times I'd like to hide it, so I can focus on work, ignoring E-mails until later. Removing the icon results in the settings being deleted, which is not a good solution, as re-adding the icon then takes many steps. How can I temporarily hide an icon in XFce4?

Freeradius proxy EAP request to non-EAP server Posted: 15 Jul 2021 09:47 AM PDT We have Keycloak SSO with the Radius plugin, which doesn't support EAP. We want to authenticate the WPA-2 Enterprise Ubiquiti network against our SSO, but it requires the support of EAP. It is possible to use FreeRadius to terminate EAP, proxy to SSO Radius server, and then convert the answer back to EAP? If yes, how it can be achieved? We have tried to apply several configurations available on the net, but no one of them converts to non-EAP request - our SSO Radius server still receives EAP request. Thank you

Installing a list of packages from an URL Posted: 15 Jul 2021 09:04 AM PDT I'm trying to install a new version of RabbitMQ on my Raspberry Pi 3, running a new raspbian image (based on debian 9). I was following the installation guide for Debian/Ubuntu, which worked for me on Ubuntu 18.04, but not on raspbian: https://www.rabbitmq.com/install-debian.html Whatever I tried to do according to the guide to force the use of their own repository (creating /etc/apt/sources.list.d/bintray.erlang.list and /etc/apt/preferences.d/erlang), when I do apt-get install erlang-nox I get a version 19.2.1 from another repository. This version does not work with newer rabbitmq-server releases, and has security holes too. So now instead, I want to manually install the erlang-nox packages, found here on the rabbitmq repository: http://dl.bintray.com/rabbitmq/debian/pool/erlang/21.0.5-1/debian/stretch/ How could I download the packages and install them all at once? Do I have to copy paste the name of all of these? Edit: I noticed there is a erlang_21.0.5-1_all.deb package at the bottom of the list, tried to download it and install it, but as it turns out it does not contain all the packages at all, it is only 36 KB.

How to get whole command line from a process? Posted: 15 Jul 2021 08:21 AM PDT How can I get the command arguments or the whole command line from a running process using its process name? For example this process: # ps PID USER TIME COMMAND 1452 root 0:00 /sbin/udhcpc -b -T 1 -A 12 -i eth0 -p /var/run/udhcpc.eth0.pid And what I want is /sbin/udhcpc -b -T 1 -A 12 -i eth0 -p /var/run/udhcpc.eth0.pid or the arguments. I know the process name and want its arguments. I'm using Busybox on SliTaz.

Disabling gpgcheck with tmprepo plugin Posted: 15 Jul 2021 10:00 AM PDT I want to install an rpm from a repo just once and not have to add it to my yum.repos.d/ directory using the tmprepo plugin. However, I'm blocked on how to install an rpm with no gpg signature. The '—nogpgcheck' option doesn't work with the tmprepo plugin and I need to manually append 'pkgs_gpgcheck=false' to /etc/yum/pluginconf.d/tmprepo.conf. sudo yum --tmprepo=http://edge.artifactory.example.com:8000/artifactory/chef_rpms/rhel/chef_rpms.repo --nogpgcheck install chef ## ^^ this fails as —nogpgcheck doesn't work with tmprepo which defaults to gpgcheck unless I manually edit /etc/yum/pluginconf.d/tmprepo.conf Any way this can be done when calling yum on command line? I don't want to go about changing a file on the system for a one-time thing. Thanks! Faheem

Parse XML to get node value in bash script?

Let me know your idea.

rm -rf all files and all hidden files without . & .. error Posted: 15 Jul 2021 08:06 AM PDT rm -rf /some/path/* deletes all non-hidden files in that dir (and subdirs). rm -rf /some/path/.* deletes all hidden files in that dir (but not subdirs) and also gives the following error/warning: rm: cannot remove directory: `/some/dir/.' rm: cannot remove directory: `/some/dir/..'
