This GitHub Page showcases a collection of personal scripts and tools I have developed. These scripts are designed to streamline tasks, automate processes, and provide solutions to common challenges in software development, server management, and system configuration.
- Automation Scripts: Tools for simplifying repetitive tasks like backups, data processing, and system monitoring.
- Server Configuration: Scripts for setting up and optimizing web servers (e.g., Apache, cPanel DNS).
- Custom Utilities: Personalized tools tailored to address unique challenges in system administration and web development.
- Networking Solutions: Scripts for managing network configurations, including IP whitelisting and Netplan setups.
The purpose of this repository is to:
- Share knowledge and resources with the developer community.
- Document my learning journey and experiences in programming and system administration.
- Provide reusable scripts for quick integration into projects.
Explore the scripts in the repository and feel free to contribute, report issues, or suggest enhancements!

- snapshot.sh will create a snapshot of the VM. It can be used as a cronjob.
Sample command:
[root@vz ~]# ./snapshot.sh
Domain snapshot alma8 2023-10-11-15:20 created
Domain snapshot alma81 2023-10-11-15:20 created
Domain snapshot opensuse 2023-10-11-15:20 created- This get_pod_logs.sh Bash script retrieves the logs of a specified Kubernetes pod in the "openstack" namespace using MicroK8s.
- Open your terminal.
- Create a new bash script file. For example, you can name it 'get_pod_logs.sh'
- Make the script executable
- Now you can use the script to get the logs of any pod by providing the pod name as an argument. For example, to get the logs of a pod named example-pod, you would run:
./get_pod_logs.sh example-pod- The add_ssl_certificate.sh script automates the process of obtaining and configuring SSL certificates for domains using Let's Encrypt.
Features
- Requests SSL certificates for specified domains.
- Automatically updates the Apache ssl.conf with the new domain's configuration.
- Backs up the existing configuration before modifications.
- Validates the Apache configuration.
- Restarts Apache to apply changes.
Usage
- Ensure you have Certbot installed and Apache is configured.
- Prepare a file named domains.txt containing the domains you want to secure, one per line.
- Run the script with sudo privileges if you use Ubuntu.
- Follow the prompts or verify the output for any errors.
sudo ./add_ssl_certificate.shRequirements
- Certbot installed (apt-get install certbot or yum install certbot).
- Apache web server installed and running.
- Access to edit /etc/httpd/conf.d/ssl.conf.
- The remove_ssl_certificate.sh script facilitates the removal of SSL certificates for domains and cleans up Apache configurations.
Features

- Manual Linux Kernel Build Script for CentOS 7 compile-kernel.sh
This script helps you manually compile and install a custom Linux kernel on CentOS 7 systems.
It is designed for:
- Learning purposes or patching custom kernel modules
⚙️ Features
- Downloads and extracts the desired Linux kernel version
- Reuses current kernel configuration (
/boot/config-*) - Compiles kernel and modules using all CPU cores
- Installs modules and kernel into
/boot - Regenerates GRUB2 boot configuration
- Sets new kernel as default boot entry
- Safe Kernel Boot Test Script safe-kernel-test.sh
This script allows you to safely test a new Linux kernel on CentOS 7 by configuring:
- ✅ Auto-reboot after kernel panic
- ✅ GRUB to boot the test kernel only once
- ✅ Automatic fallback to a working kernel if the new one fails
- ✅ Automatic marking of successful boots using
systemd
⚙️ What It Does
- Sets
kernel.panic = 10to auto-reboot 10 seconds after a kernel panic. - Configures GRUB to use saved/default boot entry logic.
- Uses
grub2-rebootto boot into a selected kernel once. - Sets up a
systemdservice (mark-boot-success) to mark the boot as successful if the system reaches multi-user mode.
- AlmaLinux Bonding Scripts
This repository contains helper scripts to easily configure and revert NIC bonding on AlmaLinux 9 (and RHEL 9 compatible systems) using NetworkManager (nmcli).
The scripts automate the setup of an 802.3ad (LACP) bond with two slave interfaces.
📌 Features
- Creates a bond interface (
bond0) in 802.3ad (LACP) mode. - Assigns a static IP (
10.10.10.116/24) and default gateway (10.10.10.1). - Automatically enslaves interfaces (
ens37f0andens37f1). - Cleans up old bond connections before creating a new one.
- Provides a revert script to restore interfaces to their original state.
📂 Files
- setup-bond.sh → Creates and configures the bond.
- revert-bond.sh → Removes the bond and restores original NICs.
- setup-bond0.sh → Creates and configures the bond for 4 NIC.
- revert-bond0.sh → Removes the bond and restores original 4 NICs.
⚙️ Requirements
- AlmaLinux 9 / RHEL 9
- NetworkManager enabled
- Root privileges
- Roundcube Log Parser
parse_roundcube_log.sh is a Bash script designed to analyze Roundcube webmail logs and extract useful statistics such as:
- Total number of login attempts
- Successful vs failed logins
- Top usernames and IP addresses
- Login activity by date and time
- Optional: suspicious IPs or brute-force attempts
It helps mail server administrators monitor and secure their Roundcube webmail environment.
- Comprehensive cPanel Permission Repair Utility
cpfixperms.sh is a Comprehensive cPanel Permission Repair Utility Safely repairs ownership and permissions for one, multiple, or all cPanel users, with logging, dry-run, and summary report.
