Data copy through pendrive logs

 To read and copy data from a USB pendrive in Linux and check its size, follow these steps: 1. Identify the Pendrive Open a terminal and run: lsblk or fdisk -l This will list all connected storage devices. Look for entries like /dev/sdb1 (it may vary). 2. Mount the Pendrive (If Not Auto-mounted) If the pendrive is not automatically mounted, create a mount point and mount it manually: sudo mkdir -p /mnt/usb sudo mount /dev/sdb1 /mnt/usb Replace /dev/sdb1 with the correct partition name. 3. Copy Data from the Pendrive Use the cp command to copy files: cp -r /mnt/usb /destination/path/ Or use rsync for a safer copy: rsync -av /mnt/usb/ /destination/path/ 4. Check Pendrive Size To check the total and available space: df -h /mnt/usb 5. Unmount After Use Once done, unmount the pendrive safely: sudo umount /mnt/ usb Let me know if you need more details! To check if data has been copied to or from a pendrive in Linux, you can analyze system logs and use tools to track USB activity. Here’s ...

System activity check

 ,sudo apt update && sudo apt install clamav -y sudo freshclam # Update virus database sudo clamscan -r /home/ # Scan home directory It looks like you might be asking about "threats" in Linux. If you're looking for ways to check for security threats or malware on a Linux system, here are some methods: 1. Check Running Processes Use the following commands to check for unusual processes: ps aux --sort=-%cpu | head -20 # Check top CPU-consuming processes ps aux --sort=-%mem | head -20 # Check top memory-consuming processes 2. Check Open Network Connections See active network connections and detect suspicious activity: netstat -tulnp ss -tulnp lsof -i 3. Check System Logs Look for unusual logs in system files: journalctl -xe dmesg | less cat /var/log/syslog | less 4. Use ClamAV for Malware Scanning ClamAV is an open-source antivirus for Linux: sudo apt update && sudo apt install clamav -y sudo freshclam # Update virus database sudo clamscan -r /home/ # S...

Airscan

 To install airscan (which is part of sane-airscan) in Linux and configure it with a Kyocera scanner, follow these steps: Step 1: Install sane-airscan sane-airscan provides support for eSCL (Apple AirScan) and WSD (Web Services on Devices) scanners, which many Kyocera models support. Ubuntu/Debian-based distributions: sudo apt update sudo apt install sane-airscan Fedora: sudo dnf install sane-airscan Arch Linux (AUR package): yay -S sane-airscan Step 2: Install SANE and Required Utilities To ensure scanning works properly, install the following: sudo apt install sane-utils Check if SANE recognizes your scanner: scanimage -L If your Kyocera scanner supports eSCL or WSD, it should appear in the list. Step 3: Configure sane-airscan By default, sane-airscan should detect supported network scanners. However, if your scanner is not detected: 1. Check for the scanner's IP If your Kyocera printer/scanner is on the network, find its IP address using: avahi-browse -rt _uscan._tcp or check yo...

Display issue

 It looks like your HP All-in-One PC is freezing under Linux in specific scenarios: 1. When you lock the screen (Win + L). 2. When the screensaver activates after 5 minutes of inactivity. 3. It works fine in presentation mode and Windows. This suggests a graphics driver or power management issue. Here’s what you can try: 1. Update Graphics Drivers If your PC has an NVIDIA or AMD GPU, install/update the correct drivers: For Intel GPUs (default for HP AIO): sudo apt update && sudo apt upgrade   sudo apt install xserver-xorg-video-intel For NVIDIA GPUs: sudo ubuntu-drivers autoinstall   reboot 2. Disable Screensaver & Lock Screen Since the freeze happens when locking or after 5 minutes of inactivity, disable them: Disable Lock Screen: gsettings set org.gnome.desktop.screensaver lock-enabled false Disable Screensaver: sudo apt remove xscreensaver 3. Change Display Server (Xorg/Wayland) At the login screen, click your username, then click the settings ico...

Mount disk issue

It looks like your PC is having an issue with the EFI boot partition. This could happen due to an improperly mounted EFI partition or a corrupted bootloader. Here’s how you can fix it: Step 1: Check EFI Partition 1. Boot into your Linux system (if it starts after the error). 2. Open a terminal and check your disk partitions by running: sudo fdisk -l 3. Look for a partition labeled EFI System (usually something like /dev/sdX1 or /dev/nvme0n1p1). Step 2: Manually Mount EFI Partition If your EFI partition is not mounted, try mounting it manually: 1. Create a mount point: sudo mkdir -p /boot/efi 2. Mount the partition (replace /dev/sdX1 with the correct partition from Step 1): sudo mount /dev/sdX1 /boot/efi Step 3: Fix fstab Entry 1. Open the fstab file: sudo nano /etc/fstab 2. Look for a line referring to /boot/efi. If missing, add: UUID=<your-efi-uuid> /boot/efi vfat defaults 0 1 Replace <your-efi-uuid> with the correct UUID (get it using blkid command). 3. Save and exit...
