Mount Windows SMB shares on Linux with on-demand automount.

⚠️ Security Notice: Passwords are entered interactively (secure prompt). Never pass passwords via command line arguments.

Security & Permissions / 安全与权限

⚠️ WARNING / 警告

• Requires sudo/root: All scripts modify system-level configurations
• Modifies /etc/fstab: Persistent changes to system mount configuration
• Creates credential files: Stores passwords in /etc/smb-creds-*.txt (mode 600, root-only)
• System impact: Incorrect usage may affect boot process

Recommendation / 建议: Review scripts before execution. Backup /etc/fstab if uncertain.

bash

# Backup fstab before using add-to-fstab.sh
sudo cp /etc/fstab /etc/fstab.backup.$(date +%Y%m%d)

---

Dependencies / 依赖

bash

# Required packages
sudo apt install cifs-utils smbclient

---

Scripts / 脚本

Script	Purpose
list-shares.sh <ip> <username>	List available shares
add-to-fstab.sh <ip> <share> <name> <username>	Persistent automount
mount-smb.sh <ip> <share> <path> <username>	One-time mount

---

Usage / 使用

⚠️ Passwords are entered interactively / 密码通过交互式输入

bash

# 1. Discover shares
# Password will be prompted securely
sudo ./list-shares.sh 192.168.2.3 Administrator
Enter SMB Password: [hidden input]

# 2. Persistent automount (mounts on first access)
sudo ./add-to-fstab.sh 192.168.2.3 workspace my-work Administrator
Enter SMB Password: [hidden input]
ls /mnt/smb/my-work    # triggers mount

# 3. One-time mount
sudo ./mount-smb.sh 192.168.2.3 workspace /mnt/temp Administrator
Enter SMB Password: [hidden input]

---

How it works / 工作原理

• noauto → not mounted at boot
• x-systemd.automount → mounts on first access
• credentials=/etc/smb-creds-*.txt → password not in fstab
• Interactive password input → no command-line exposure

---

Files / 文件

• Mountpoints: /mnt/smb/<name>/
• Credentials: /etc/smb-creds-<name>.txt (mode 600, root-only)

中文说明

在 Linux 上自动挂载 Windows SMB 共享。按需挂载，凭证交互式输入，命令行不暴露密码。

安全警告

• 需要 sudo/root 权限：修改系统级配置
• 修改 /etc/fstab：持久化更改系统挂载配置
• 创建凭证文件：密码存储在 /etc/smb-creds-*.txt（权限 600，仅 root 可读）
• 系统影响：错误使用可能影响启动过程

建议：执行前审查脚本。不确定时备份 /etc/fstab。

依赖

bash

sudo apt install cifs-utils smbclient

使用

⚠️ 密码通过交互式安全输入，不通过命令行参数

bash

# 1. 发现共享
# 密码会安全提示输入
sudo ./list-shares.sh 192.168.2.3 Administrator
Enter SMB Password: [隐藏输入]

# 2. 持久化挂载（首次访问时自动挂载）
sudo ./add-to-fstab.sh 192.168.2.3 workspace mywork Administrator
Enter SMB Password: [隐藏输入]
ls /mnt/smb/mywork    # 触发挂载

# 3. 一次性挂载
sudo ./mount-smb.sh 192.168.2.3 workspace /mnt/temp Administrator
Enter SMB Password: [隐藏输入]

工作原理

• noauto → 启动时不挂载
• x-systemd.automount → 首次访问时自动挂载
• credentials=/etc/smb-creds-*.txt → fstab 中无密码
• 交互式密码输入 → 命令行不暴露

文件

• 挂载点：/mnt/smb/<name>/
• 凭证文件：/etc/smb-creds-<name>.txt（权限 600，仅 root）
