| Android file copy gives errors with simple-mtpfs and rsync on Fedora Posted: 20 Aug 2021 11:06 AM PDT I am no longer able to reliably copy files off my Android phone using simple-mtpfs and rsync. I use simple-mtpfs -l to verify that the mtp device is available, and simple-mtpfs -device 1 to mount this device to my filesystem, then rsync to copy files from the mountpoint location. This procedure used to work. It broke sometime after I upgraded to Fedora 31. Now many, but not all files fail to copy. I get rsync errors on the failed copies such as: No data available (61) failed verification -- update discarded (will try again). and Numerical result out of range (34) Problem seems to not be in the phone, I can connect it to an old machine running Fedora 26 and use exactly the same procedure (simple-mtpfs, rsync) and copy the files with no errors. I am running Fedora 33 xfce spin with kernel 5.13.9-100.fc33.x86_64 on an HP Pavilion a6209n with an AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ CPU. Can someone please suggest a fix? If any additional information is required in order to diagnose this bug, please let me know what it is and where to find it. So far all I have been able to find is the previously listed errors that come to the console. Nothing additional related to simple-mtpfs, fuse, or libmtp anywhere that I have looked.  |

| View command in ubuntu [duplicate] Posted: 20 Aug 2021 10:49 AM PDT According to manpage of vim, view is similar to vim -R on ubuntu. But, when I did ls -l /bin/view I found out that view is a symlink to /etc/alternatives/view which in turn points to /usr/bin/vim.basic. Coincidentally on my system, /bin/vim -> /etc/alternatives/vim -> /usr/bin/vim.basic. So both vim and view points to the same binary. Hence when we open any file with view there must be an intermediary which invokes the vim editor in read-only mode which I am not able to figure out where it is. Please help. My system, OS - Ubuntu 20.04 LTS kernel - 5.8.0-63-generic.  |

I'm a little bit confused, I also can select PulseAudio as sound card, when changing my output volume there it changes the volume on the Scarlett.

| Why does caps lock cause my Apple M1 to stutter? Posted: 20 Aug 2021 09:01 AM PDT This question is more for fun since it isn't hurting me. I ought to file a bug instead of posting here, but I only have time to blow to do one or the other, and re-locating all the info to file a bug properly with Apple would be exhausting and probably not result in anything anyway. Fairly heavily loaded M1 mac pro (think hundreds of chrome tabs). Activity monitor says it is 80% idle. I was playing a youtube video on chrome (probably not the native version), and noticed that hitting the caps lock key would cause the music to stutter. Opening up activity monitor and hitting the caps lock key repeatedly causes idle percent to drop to 40% and plenty of stuttering. What gives? If I didn't see it myself, I would not believe it, as I don't recall ever having seen a working system behave like this.  |
| Need to find the difference between two table sizes in postgres using shell script Posted: 20 Aug 2021 11:14 AM PDT I have one table named 'Table_size_details' in my database which stores the size of the tables in my Postgres database, every Friday. Date Table_Name Table_size Growth_Difference Growth_Percentage ---- ----------- ---------- ----------------- ----------------- 20-08-2021 Demo 1.2 GB 13-08-2021 Demo 578 MB
I have got a task to add two more columns named 'Growth_Difference' and 'Growth_Percentage'. In 'Growth_Difference' column I need to find the difference between current table size(1.3 GB) and previous week table size(578 MB) and display it in MB format. Also I need to find the growth percentage of both- the current table size and previous week's table size. I have asked to develop using SHELL SCRIPT. Table_size_old=`psql -d abc -At -c "SELECT Table_size_details from abc order by Date desc limit 1;"` Table_size_new=`psql -At -c "SELECT pg_size_pretty(pg_total_relation_size('Table_size_details'));` growth_table=`expr $Table_size_new - $Table_size_old;`
Above logic I have used to find the difference between new and old table size but I'm getting expr: syntax error on growth_table variable line. I believe its because I trying to find the difference between 1.2 GB and 578 MB. I'm new to shell scripting, could anyone help me to find a solution? Appreciate your help in advance.  |
| SELinux is preventing /usr/sbin/rsyslogd from write access on the directory / Posted: 20 Aug 2021 08:52 AM PDT My goal is to create rsyslog config file that could log every Failed attempt to sshd.service in a different file on Centos Stream machine. So I recently added a config file in /etc/rsyslog.d/ called ssh_spam.conf. Contents of this configuration file is as follows: if $msg contains "Failed password for" then action(type="omfile" file="/var/log/ssh_spam.log")
After using this configuration and restarting rsyslog.service I noticed a lot of SELinux errors in journalctl that look like this: Aug 20 17:54:32 cos0.localdomain setroubleshoot[1432261]: SELinux is preventing /usr/sbin/rsyslogd from write access on the directory /. For complete SELinux messages run: sealert -l ee49959c-8894-46e0-baa7-544c4341d219 Judging by ssh_spam.log file is seems to work correctly, I understand what SELinux is doing, but I don't understand why rsyslogd is trying to write in / directory.  |

| Command working in interactive shell but not in script [duplicate] Posted: 20 Aug 2021 09:00 AM PDT - Platform: RHEL7
- Shell: Bash
- Expected Result: store value as a variable
I'm trying to capture an IP from text that looks like this: { "ip": "12.34.56.7", "type": "LEARNED" }
When I run the following command from the terminal, I get the IP as expected. grep '"ip":' ../path/to/file.txt | awk '{ print $2 }' | tr -d '"' | tr -d ','
Below is what I have in the script: IP=grep '"ip":' ../path/to/file.txt | awk '{ print $2 }' | tr -d '"' | tr -d ','
I've tried a few different things, such as putting everything after IP= in quotes or escaping the quotes around the grep ip text with \\ but no dice. I'm just not sure of the right method of going about this. The script either breaks apart my command if it doesn't have quotes, or for some reason it drops the $2 from awk. Thanks for any info.  |

| is there a distribution that makes running and logging in as root workable out of the box? Posted: 20 Aug 2021 09:27 AM PDT all I ever use linux for is things that require root, e.g., modifying partitions on usb drives. I'd like to just log in as root and run X11 without being hassled about it every time I turn around. Is there a linux distribution that works that way? I don't want to use a gparted live cd as I do other hardware hacking as well, so a genuine installable OS would be preferred. in older versions of ubuntu it wasn't hard to enable the root user but seems to be impossible (I just tried in a recent version of ubuntu mate). before everybody leaps over themselves to save me: I just want to know how to do what I've asked, not the 1000s of reason why it's the worst idea in the world. Thank you for your understanding.  |
| ssh backspace not working until I manually run TERM=xterm Posted: 20 Aug 2021 09:04 AM PDT I understand that backspace might now work in an ssh session if TERM is set incorrectly. But strangely, I have a server where TERM is set correctly, but backspace does not work until I manually set TERM=xterm in the shell (which should be redundant). See here: ~ ] ssh root@192.168.10.40 root 192.168.10.40 / # echo $0 -bash root 192.168.10.40 / # echo $TERM xterm-256color root 192.168.10.40 / # # backspace does not work :( root 192.168.10.40 / # root 192.168.10.40 / # TERM=xterm-256color root 192.168.10.40 / # # now backspace works!! root 192.168.10.40 / # logout
I would say about 90% of the time, backspace does not work until I run TERM=xterm, and 10% of the time, I don't need to run the TERM= command because backspace is already working. I've compared the output of env for each case, and they are identical (aside from SSH_CLIENT and SSH_CONNECTION where only the client side port has changed) Any idea what may cause this behavior, or what a workaround might be?

bind -p|egrep 'delete|rubout|kill' also shows no different before and after setting XTERM. Output is:

Interestingly, if I source my bashrc, my backspace starts working again. I know the bashrc is being sourced on login though because that is the only place where I set my Ps1 value  |
| How can I make a scrolling matrix terminal background? Posted: 20 Aug 2021 11:04 AM PDT There are many scripts/programs that will turn your terminal into a matrix style screensaver, however I want to use it as a terminal wallpaper and still be able to use my terminal. I haven't been able to find anything online concerning any sort of animated terminal background. Would it be especially difficult to write something that can handle this?  |
| How to Setup Triple Monitors with Kali Linux? Posted: 20 Aug 2021 10:58 AM PDT I installed Kali Linux 2 on my laptop and need to configure a triple monitor setup with it. At the moment, I have a Belkin Dual DVI docking station and a Startech DVI to USB 3 converter. On Windows 7, I had two of my monitors use DVI to connect to the Docking station and the third monitor used a USB 3 port on the Docking station. Here is a picture of my setup on Windows 7 which worked perfectly okay: 
An here is a picture of my Docking station:  Here is a link if you want to know more about the Belkin docking station: https://www.amazon.co.uk/Belkin-B2B122-BLK-Display-Docking-Ultrabooks/dp/B00JG0ZG8Q Now, when I launch Kali 2 and connect my Belkin Docking station, one of my screens turn green but the other 2 remain off: 
Running lsusb before connecting the docking station looks like this: root@kali:~# lsusb Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 064e:9301 Suyin Corp. Bus 001 Device 002: ID 0781:5567 SanDisk Corp. Cruzer Blade Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Running lsusb while the docking station is connected shows the following: root@kali:~# lsusb Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 002: ID 8087:0024 Intel Corp.

Bus 001 Device 011: ID 2109:2812 VIA Labs, Inc. VL812 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Here is my video card information: root@kali:~# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Here is the result of xrandr command: root@kali:~# xrandr Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767 LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 345mm x 194mm 1366x768 59.99*+ 40.00 1360x768 59.80 59.96 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis)
After some testing I found that my mouse and keyboard are recognized through the Docking Station, however, for some reason the DVI's are not. looking at the result of lsusb I noticed that DisplayLink maybe the manufacturer and driver so I did some googling and found that they support Ubuntu but not Debian. Digging a bit deeper, found a script on Github that said it will install DisplayLink drivers for Debian so I used it, however, it said my platform is not supported! root@kali:~/Downloads# ./displaylink-deb.sh DisplayLink driver for Debian GNU/Linux [I]nstall [U]ninstall Select a key: [i/u]: i Checking dependencies... unzip is installed linux-headers-4.3.0-kali1-amd64 is installed dkms is installed lsb-release is installed ------------------------------------------------------ Unsuported platform: Kali kali-rolling This tool is Open Source and feel free to extend it GitHub repo: https://goo.gl/6soXDE ------------------------------------------------------ root@kali:~/Downloads#
It may also be worth mentioning that when I open Kali from VMWare Workstation on Windows 7 I'm able to use all 3 monitors:  Any advice is really appreciated.

I tried changing the user that Apache is running, but that hasn't solved the issue. <IfModule unixd_module> # # If you wish httpd to run as a different user or group, you must run # httpd as root initially and it will switch. # # User/Group: The name (or #number) of the user/group to run httpd as. # It is usually good practice to create a dedicated user and group for # running httpd, as with most system services. # #User _www #Group _www User crmpicco Group staff </IfModule>
Am I missing something obvious? I have also tried this suggestion (Apache localhost 403 error with Yosemite)  |
| Audio 'pops' in when starting and stopping Posted: 20 Aug 2021 11:21 AM PDT Whenever audio starts playing, or stops playing, a 'popping' sound can be heard from my headphones. I am running Elementary OS 0.3.2 Freya, and the issue only happens when I am using headphones. The 'popping' also happens when I plug my headphones in and when wifi has connected or disconnected.  |
