SSH Access with sshpass

Date: 2025-12-13
Status: ✅ CONFIGURED

---

Overview

All SSH scripts have been updated to use sshpass with the password from .env file (lines 45-46).

---

Quick Access Scripts

SSH to ML110-01

./scripts/ssh-ml110-01.sh

SSH to R630-01

./scripts/ssh-r630-01.sh

Execute Commands Remotely

# ML110-01
./scripts/ssh-ml110-01.sh 'pveversion'
./scripts/ssh-ml110-01.sh 'qm list'
./scripts/ssh-ml110-01.sh 'pvesm status'

# R630-01
./scripts/ssh-r630-01.sh 'pveversion'
./scripts/ssh-r630-01.sh 'qm list'
./scripts/ssh-r630-01.sh 'pvesm status'

---

Manual Commands

Using sshpass Directly

ML110-01:

PROXMOX_PASSWORD=$(sed -n '45,46p' .env | grep PROXMOX_ROOT_PASS | cut -d'=' -f2 | tr -d '"' | tr -d "'")
sshpass -p "$PROXMOX_PASSWORD" ssh root@192.168.11.10

R630-01:

PROXMOX_PASSWORD=$(sed -n '45,46p' .env | grep PROXMOX_ROOT_PASS | cut -d'=' -f2 | tr -d '"' | tr -d "'")
sshpass -p "$PROXMOX_PASSWORD" ssh root@192.168.11.11

---

Password Source

The password is automatically loaded from .env file:

• Location: Lines 45-46
• Variable: PROXMOX_ROOT_PASS
• Format: Automatically extracted and cleaned

---

Updated Scripts

• Displays SSH commands with sshpass
• Shows password status
• Provides verification commands

2. scripts/ssh-ml110-01.sh

• Quick SSH to ML110-01
• Password loaded automatically
• Supports command execution

3. scripts/ssh-r630-01.sh

• Quick SSH to R630-01
• Password loaded automatically
• Supports command execution

4. scripts/test-proxmox-connectivity.sh

• Uses sshpass for SSH tests
• Automatically loads password
• Tests both nodes

---

Example Usage

Check Proxmox Version

# ML110-01
./scripts/ssh-ml110-01.sh 'pveversion'

# R630-01
./scripts/ssh-r630-01.sh 'pveversion'

List VMs

# ML110-01
./scripts/ssh-ml110-01.sh 'qm list'

# R630-01
./scripts/ssh-r630-01.sh 'qm list'

Check Storage

# ML110-01
./scripts/ssh-ml110-01.sh 'pvesm status'

# R630-01
./scripts/ssh-r630-01.sh 'pvesm status'

Interactive SSH Session

# ML110-01
./scripts/ssh-ml110-01.sh

# R630-01
./scripts/ssh-r630-01.sh

Security Notes

⚠️ Important:

• Password is stored in .env file (should be in .gitignore)
• sshpass passes password via command line (visible in process list)
• For production, consider using SSH keys instead

Recommended: Setup SSH Keys

# Generate key
ssh-keygen -t rsa -b 4096 -f ~/.ssh/proxmox_key

# Copy to both nodes
./scripts/ssh-ml110-01.sh 'mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys' < ~/.ssh/proxmox_key.pub
./scripts/ssh-r630-01.sh 'mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys' < ~/.ssh/proxmox_key.pub

# Then use key-based auth
ssh -i ~/.ssh/proxmox_key root@192.168.11.10
ssh -i ~/.ssh/proxmox_key root@192.168.11.11

Troubleshooting

sshpass Not Installed

# Ubuntu/Debian
sudo apt-get install sshpass

# RHEL/CentOS
sudo yum install sshpass

Password Not Found

Check .env file:

sed -n '45,46p' .env

Should show:

PROXMOX_ROOT_PASS=L@KERS2010

Connection Issues

Test connectivity:

ping -c 3 192.168.11.10
ping -c 3 192.168.11.11

Test SSH manually:

ssh -v root@192.168.11.10

Conclusion

✅ All scripts updated to use sshpass

• Password automatically loaded from .env
• Quick access scripts available
• Connectivity tests use sshpass
• Ready for automated operations
