SSH Setup Troubleshooting

Last Updated: 2024-12-19

Current Issue

SSH key copy is failing with "Permission denied" even though:

✅ PROXMOX_ROOT_PASS is in .env
✅ sshpass is installed
✅ SSH key exists: ~/.ssh/sankofa_proxmox

Possible Causes

1. Password Authentication Disabled

Proxmox may have password authentication disabled for security. Check:

# On Proxmox node (via Web UI Shell or console)
grep -i "PasswordAuthentication" /etc/ssh/sshd_config

If PasswordAuthentication no, enable it temporarily:

# On Proxmox node
sed -i 's/#PasswordAuthentication yes/PasswordAuthentication yes/' /etc/ssh/sshd_config
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config
systemctl restart sshd

2. Incorrect Password

Verify the password in .env matches the actual root password on Proxmox nodes.

3. SSH Key Already Exists

The key may already be on the server. Check:

ssh -i ~/.ssh/sankofa_proxmox root@192.168.11.10 'cat ~/.ssh/authorized_keys | grep sankofa'

Check if root login is allowed:

# On Proxmox node
grep -i "PermitRootLogin" /etc/ssh/sshd_config

Alternative Methods

Method 1: Use Proxmox Web UI Shell

Log in to https://ml110-01.sankofa.nexus:8006
Go to: Datacenter → Nodes → ML110-01 → Shell

Run:

mkdir -p ~/.ssh
chmod 700 ~/.ssh
echo "YOUR_PUBLIC_KEY_HERE" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

Method 2: Manual SSH Copy (Interactive)

# This will prompt for password
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.10
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.11

Method 3: Use Existing SSH Access

If you already have SSH access via another method:

# Copy key using existing access
cat ~/.ssh/sankofa_proxmox.pub | ssh root@192.168.11.10 'cat >> ~/.ssh/authorized_keys'
cat ~/.ssh/sankofa_proxmox.pub | ssh root@192.168.11.11 'cat >> ~/.ssh/authorized_keys'

Verification

After adding keys, test:

ssh -i ~/.ssh/sankofa_proxmox root@192.168.11.10 'hostname'
ssh -i ~/.ssh/sankofa_proxmox root@192.168.11.11 'hostname'
