KIETWIFI

A bash script that automates the process of logging into KIET's college and hostel wifi. It securely stores credentials and can be configured to run automatically at system startup.

Features

• One-time credential setup and secure storage
• Automatic login on system startup
• Proper error handling and exit codes

Prerequisites

• bash shell
• curl
• wget
• systemd (optional, for service installation)

Installation

1. Download the script:

sudo wget -O /usr/local/bin/wifi_login.sh https://raw.githubusercontent.com/VanshSahay/kietwifi/main/wifi_login.sh

2. Make the script executable:

sudo chmod +x /usr/local/bin/wifi_login.sh

Configuration

On first run, the script will prompt for:

• Username
• Password

These credentials are stored securely in ~/.wifi_credentials with restricted permissions (600).

Usage

Manual Execution

/usr/local/bin/wifi_login.sh

Automatic Startup

Type=oneshot
ExecStart=/usr/local/bin/wifi_login.sh
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

3. Enable and start the service:

sudo systemctl enable wifi-login.service
sudo systemctl start wifi-login.service

Troubleshooting

1. Login Failures

   • Check if credentials are correct
   • Verify network connectivity
