| What is the best way to pipe the output of Grep -Ri to file? Posted: 09 Apr 2021 10:14 AM PDT Grep -Ri can be piped to a file directly. The problem with this is that the the log name is not clear as it is hidden to the left of the timestamp in the same font color. Would it be possible to improve this. Like to color each .log entry on the left a different color, to color only the timestamp aspect, or to put the name of the log only once at the top of each file grep -Ri outputs. If grep -Ri can't be used for this, what are the best alternatives and options. grep -Ri "2021-04-06T05:2" > log; cat log | grep -vi info | less
This works nicely. Im trying to figure out how to refine the above output is all.  |
| Can't play CD on fedora: no medium found on /dev/sr0 Posted: 09 Apr 2021 10:06 AM PDT When I insert a DVD into the drive on my PC under Fedora 33, vlc opens the disk automatically and begins to play it. When I insert a CD (audio or data), the drive spins up and the light blinks, but the disk fails to automount. The disk doesn't appear in Rhythmbox or Files. When I try to mount with mount /dev/sr0 /tmp, I get mount: /tmp: no medium found on /dev/sr0. I can successfully eject the drive. I have installed all the recommended gstreamer plugins and can see no obvious errors in the following commands $ lsblk $ lspci $ dmesg | egrep -i --color 'cdrom|dvd|cd/rw|writer' $ cdrecord -prcap dev=/dev/cdrom $ ls -l /dev/sr0
The audio CDs play fine in another dvd drive on my ancient laptop. I've recently upgraded from Fedora 32 so all the libraries are up to date. As far as I can recall, I've never bothered playing CDs from this machine. It's been a long time since I've had to deal with CD/DVD issues, so there could be something in the last 5-10 years that I haven't kept up with. I'm still coming up to speed with systemd. ;) The only errors I can spot are from journalctl /dev/sr0 Apr 09 11:57:52 corvus kernel: ahci 0000:00:1f.2: AHCI 0001.0300 32 slots 5 ports 6 Gbps 0x5 impl SATA mode kernel: ahci 0000:00:1f.2: flags: 64bit ncq pm led clo pio slum part ems apst kernel: scsi host2: ahci kernel: scsi 2:0:0:0: CD-ROM hp DVD-RAM UJ8E1 4H01 PQ: 0 ANSI: 5 kernel: sr 2:0:0:0: [sr0] scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray kernel: sr 2:0:0:0: Attached scsi CD-ROM sr0 kernel: sr 2:0:0:0: Attached scsi generic sg1 type 5 kernel: sr 2:0:0:0: [sr0] tag#23 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE cmd_age=0s kernel: sr 2:0:0:0: [sr0] tag#23 Sense Key : Not Ready [current] kernel: sr 2:0:0:0: [sr0] tag#23 Add.

| laptop fan does not turn back on when exiting sleep mode Posted: 09 Apr 2021 09:49 AM PDT I am using: After restarting my computer, my laptop fan works normally. But, once I close the lid to put the laptop to sleep, the fan will not turn on after waking up (until the next restart) Sometimes the fan will turn on briefly (<1 sec) when entering/exiting sleep mode, but that's it. I specifically remember the fan working properly in the past, and I think this issue only started a few months ago.  |
| Runing alias or function in background Posted: 09 Apr 2021 09:49 AM PDT I am connecting to an OpenVPN server from my Linux Mint 19.1 machine. As the Network manager is not setting up routes properly is one uses the GUI to connect I connect by executing: sudo openvpn --config <config-file.ovpn> &
To make things easier I have stored all my VPN settings in a hidden folder using a specific tree structure. I wanted to define an alias or a function that executes the above command with a particular VPN setting, that I can call from anywhere.
I've added the following to my .bashrc alias OpenVPN='read -p "VPN name: " VPN_NAME my_path=~/.openvpn.confs/${VPN_NAME}/OpenVPN VPN_CONF=${my_path}/vpnconfig.ovpn sudo openvpn --config $VPN_CONF'
This works well but I have to keep the terminal open as it runs in interactive mode. I wanted to have it spin up and run in the background so I added a "&" to the last command, which works fine if I call that command manually from the terminal. sudo openvpn --config $VPN_CONF & But when I add it to the alias, the system still thinks it is running continuously in the background, but the connection does not work.
I also tried running it as a function, which does not connect either. OVPN() { sudo openvpn ~/.openvpn.confs/"$@"/OpenVPN/vpnconfig.ovpn & }
Any suggestions for how this might be solved?  |

| Debian 10 KDE - Can't connect to WiFi Posted: 09 Apr 2021 09:45 AM PDT nmcli general status and nmcli connection show and nmcli device status all give me a reasonable output, but nmcli dev wifi list does nothing. What am I doing wrong? I am using an intel PCI WiFi-card, so I apparently need the package iwlwifi-7260-ucode-25.30.14.0, which I downloaded and extracted. But what do I do with that? The README told me to copy a file called iwlwifi-7260-14.ucode into the /lib/firmware directory, but it did nothing. Restart didn't change anything of the before mentioned.

| Darkice not dying when audio device goes away Posted: 09 Apr 2021 09:36 AM PDT I have darkice that is transmitting a stream to an icecast server. Icecast is started by systemd. When the USB device is disconnected I see in the logs Apr 09 12:24:32 scanner1 darkice[3803072]: DarkIce: AlsaDspSource.cpp:265: No such device [0]
Which I would expect since the device was removed. When this happens icecast does not die but simply hangs. This is on a CentOS system. I ideally would like for darkice to die so that systemd could see that and then restart darkice.  |

| Buffer overrun with Darkice Posted: 09 Apr 2021 09:30 AM PDT I have two USB audio devices connected to a USB hub that then connects to a PC. The USB hub has external power. I am using darkice to transmit a stream to an icecast server. Every so often I get in the logs: Apr 09 12:24:27 scanner1 darkice[3803072]: AlsaDspSource :: Buffer overrun! Apr 09 12:24:28 scanner1 darkice[3803072]: AlsaDspSource :: Buffer overrun! Apr 09 12:24:29 scanner1 darkice[3803072]: AlsaDspSource :: Buffer overrun! Apr 09 12:24:30 scanner1 darkice[3803072]: AlsaDspSource :: Buffer overrun!
If I kill darkice and restart it, it wont help. The only way to fix the issue is to remove the USB device and then connect it a few minutes later. Sometimes the issue happens after a few minutes and sometimes after a few days. What would cause this? Is this a USB issue or strictly something with darkice?  |

| Can't access grub to restore sudo [duplicate] Posted: 09 Apr 2021 08:59 AM PDT I mistakenly ran a command that made sudo no longer a set-uid binary and it's no longer owned by root and now I can use it at all.

| Find pattern on multiple lines within BIG log files Posted: 09 Apr 2021 09:34 AM PDT To investigate within logs, I am trying to find the very first time a vulnerability in a workflow has been exploited. The pattern is on multiple lines. The pattern would be AAAAAAAAA BBBBBBBBB CCCCCCCCC
The problem is that AAAAAAAAA
or BBBBBBBBB
or CCCCCCCCC
Can be found anywhere indivdually in the log without showing the vulnerability; it is the exact pattern in this exact order that will help me. For example grep -Ei "AAAAAAAAA|BBBBBBBBB|CCCCCCCCC" logfile does not help me since all the lines with individual occurence of AAAAAAAAA BBBBBBBBB CCCCCCCCC will be there.
How can I solve this?  |

when I run this using a non-root terminal, it runs alright. It raises an access denied error but that's still fine. when I run this using a root terminal, it executes all the way through. I'm checking /var/log/cron and it does not show any errors whatsoever. Also with /var/log/messages, I don't see any errors with the python call. What the python script does is it converts tsv to xlsx, and it deletes the raw files. But it does not delete the file.  |

| Encrypting home directory on Raspberry pi with password file on USB Posted: 09 Apr 2021 10:07 AM PDT I have been trying to follow this guide: https://www.howtoforge.com/tutorial/how-to-encrypt-directories-and-partitions-with-ecryptfs-on-debian/ to encrypt the home directory on my pi with out a password by saving the password on a file onto a usb. But the issue is that the pi boots up to a login screen and prompts for a password. The only difference to the configuration in the guide I have made is that my usb is ntfs and the name of the directory that is being encrypted (pi) and the password. I tried it again and afterwards when the pi booted up it said root account was locked and I only had command line access to the system. Are there any passwordless encryption alternatives that I can use? As the pi will have a display but no keyboard.  |

| Delaying kernel upgrades on Arch Linux Posted: 09 Apr 2021 10:27 AM PDT On Arch Linux, whenever a kernel upgrade is applied (via pacman -Su), problems occur. For example, iptables can no longer be used: # iptables -L iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.
VMWare can't find the kernel headers: 
Now, I want to have kernel upgrades applied, but I'd like to defer them until I can (or want to) restart the system (remind anyone of Windows?). Otherwise, if my work is blocked on iptables or VMWare or some other program, I have no choice but to restart and rebuild a session. How can I do that? Ideally I'd like to continue using pacman -Su, but have certain upgrades deferred. I believe Is it normal that a restart is required to mount USB after a kernel upgrade? is caused by the same problem.  |

This is Gentoo but on Arch, I can find this. There is mention somewhere of a powerdown package on Arch which allows "graceful" suspend/resume. I suspend with: echo -n "mem" > /sys/power/state
So should I worry about anything and is there anything wrong with the way I suspend my system? As suggested, I have run one full pass with memtest86+ (15mins, 12 tests I think) and no errors came out. This is 2x2gb Corsair. This rig is burnt in and very stable. I have compiled over 1000 Gentoo packages on this.
Further testing After a community member identified a kernel patch which had been deployed to solve exactly this error(Revert "epoll: use freezable blocking call"), I tried to apply the patch to my sources. It turns out I already have the patch installed!? I also installed the suspend package which contains s2ram etc. This utility seemingly does nothing different in the way it suspends the computer. I compared logs of suspend and wake up events from using s2ram and then from using the command I use and there is no difference. I conclude that in that respect there is nothing wrong in using echo -n "mem" > /sys/power/state. I also validated with ethtool that wake on lan is disabled (supports wake on: pg / wake on: d) so it should not interfere with power events if I understand correctly. Maybe a setting in the bios? Or that bios is no longer updated and will trigger that exception and we'll have to live with that.  |
| Setting default username and group for files in directory Posted: 09 Apr 2021 09:00 AM PDT Using this helpful post I am able to set a default group and file permissions in a folder. I'm having trouble setting a default owner (teamlead uid 1234). setfacl -d -m g::rwx /my/test/folder setfacl -d -m o::rx /my/test/folder getfacl /my/test/folder # file: /my/test/folder # owner: teamlead # group: web_prod # flags: -s- user::rwx group::r-x other::r-x default:user::rwx default:group::rwx default:other::r-x
With that: [mary@boxen]# touch /my/test/folder/somefile [mary@boxen]# ll /my/test/folder/somefile -rw-rw-r--. 1 mary web_prod 0 Nov 6 08:58 somefile
So the right group is assigned, but the new file has ownership of the user creating the file. I'd like newly created files to have teamlead:web_prod owner/group. It appears that setfacl can be used to set a default user, too. With the existing folder acl config (above): [mary@boxen]# setfacl -d -m u:1234:rwx /my/test/folder
Now to create a file as a different user. I'm expecting it to have teamlead:web_prod ownership. [mary@boxen]# touch /my/test/folder/anotherfile [mary@boxen]# ll /my/test/folder/anotherfile -rw-rw-r--+ 1 mary web_prod 0 Nov 6 08:58 somefile
New file still has ownership of the owner creating the file, not uid 1234(teamlead). Is what I'm after even possible, or is the way I'm going about this wrong?  |
| How to run the terminal using keyboard shortcuts in Gnome 2? Posted: 09 Apr 2021 09:45 AM PDT I'm using Gnome 2. I use the terminal several times, and I lose a lot of time going in Applications / Utilities / Terminal to launch the terminal. I am wondering if I can launch the terminal using keyboard shortcuts. I would like to do something similar to CTRL+T.  |
