Why does my Linux server freeze up?
There are several possible causes of a Linux server freezing up. The most common causes are memory leaks, hardware and software incompatibilities, outdated software, insufficient disk space, misconfigured services, and a system overload. It is important to try to determine the source of the problem before attempting to resolve it. If the problem persists, it may be necessary to restart the system or back up important data and restore the server.

How to check if a Linux driver is working?
1. Run the command "lsmod" to check the installed modules and their status. 2. Check the device log files with their entry in the /var/log/ directory. 3. Check the device name or driver name in the output of the command “lsusb” or “lspci -v.” 4. Inspect the output of “dmesg” command. 5. Utilize “lshw” command to know more about the driver. 6. Confirm if the driver is loaded with “modinfo module_name” command. 7. Under sysfs, check the state file of the drivers in the path /sys/devices/module_name/state. 8. Search for the driver in “/proc/interrupts” to identify any hardware interrupts.

How to take Linux file system backup?
1. Create a Full Backup of Your Linux File System To back up all files, directories, and system data from your Linux file system, you can use the built-in command line utility, tar (tape archive). Using tar, you can easily create a full backup of your file system and save it to an external drive. To begin, use the following command to make a copy of the Linux system file system in the same PATH you are currently in. $ tar -cvpf /backup/backup.tgz / The -cvpf flags indicate that tar should create (-c) a verbose copy (-v) with preservation (-p) of ownership, permissions and all directories, files, and link (-f) from the root directory / . The output file (/backup/backup.tgz) is where the tar archive containing the backup will be stored. 2. Use the rsync Command Another option to back up your file system is to use the rsync command. rsync is a great utility for quickly backing up files and directories locally or remotely. To back up a complete system file system, you can use the rsync command as indicated below: $ rsync -azvh --delete / /backup/rsync_backup The switches and flags used with rsync are: archive (-a), compresses file data (-z), is verbose (-v), and provides information on a transfer’s progress (-h). The additional --delete flag helps ensure that all files and directories in the source are also included in the backup without needing to manually list each one. 3. Create a Clone of Your Linux File System Another option for backing up your entire Linux file system is to create a clone of the file system using a command-line based disk cloning utility such as partclone. Partclone is a utility used for creating disk images or cloning partitions for backup purposes. The partclone command used for cloning a filesystem is as follows. $ partclone.ext4 -c -s /dev/sda1 -o /backup/filesystem_clone.img The flags used in this command are used to clone (-c) a source partition (-s) located at /dev/sda1. The clone output (-o) is stored in /backup/filesystem_clone.img. Once the cloning process completes, the cloned image can be mounted and used to restore the original file system. Conclusion Backing up your Linux file system is an important part of system administration. Thankfully, with a few simple commands, you can easily make a complete backup of your Linux file system just in case it ever gets corrupted or you need to restore a file or two.

What is page cache in Linux?
Page cache in Linux is a memory management technique used to optimize disk access performance. This works by caching recently accessed files in RAM so that future requests for the same file can be provided more quickly. This increases disk access performance, as the system can quickly retrieve a file from memory without having to read from disk again.

How to connect a Linux desktop to a remote server?
1. Establish a secure connection: Secure connections can be established using SSH, a secure user authentication protocol. Make sure both computers are connected to the same network and you have access to the remote server. You can then open a terminal window on your Linux desktop and use the ssh command to connect to the remote server. For example, if the IP address of the remote server is 192.168.1.130, you can type ssh [email protected] in the terminal window to initiate the connection. 2. Log into the remote server: Once connected, you will be asked to provide the username and password (if applicable) of the remote server. 3. Copy files: You can copy files from your Linux desktop to the remote server using the scp command. For example, scp <path of local file> <username>@<remote_server_IP>:<path of remote directory>. 4. Execute remote commands: You can execute remote commands on the remote server using the ssh command itself. For example, ssh [email protected]<remote_server_IP> <command>. You can also use FTP or SFTP to transfer files between your Linux desktop and the remote server.

How to mount a filesystem in Linux?
1. Determine the filesystem type by using the command “file -s device”, where device is the device name. 2. Mount the filesystem using the command “mount -t type device mntpoint”, where type is the filesystem type, device is the device name, and mntpoint is the mount point. 3. If the filesystem requires options, such as permissions and read/write access, you can use the “-o” option in the mount command, followed by the specific option(s) desired. 4. To unmount the filesystem, use the command “umount device”, with the device name as the argument.

How do I enable application logging for Linux apps?
The specific process for enabling application logging for a Linux system will vary depending on the type and configuration of the application being used. Generally speaking, the steps are as follows: 1. Review the application's documentation to determine the log files and configuration options available. 2. Open the application's main configuration file in a text editor. 3. Set the logging level to enable log file generation. 4. Configure the application to output log data in the appropriate format (e.g. syslog, custom log file format, etc.). 5. Configure logging for the particular application (e.g. rotation interval, log file size, etc.). 6. Restart the application for the changes to take effect.

How to disable or set SELinux to permissive mode?
1. To disable or put SELinux into permissive mode, you can use the following command: sudo setenforce 0 2. You can also edit the /etc/selinux/config file and set the SELinux mode to permissive. To do this, open the config file in a text editor, find the line that reads SELINUX=enforcing, then change it to SELINUX=permissive. Save and close the file, then reboot your system for the change to take effect. 3. You can also use the graphical interface provided by your Linux distribution. Look for the settings for SELinux in the Security or Administrative Tools section. You can then select the permissive mode and save the settings.
