.pem Files Location Summary

Files Found

1. Validator Keys (Besu Validator Keys)

Location: /home/intlc/projects/smom-dbis-138/keys/validators/

These are Besu validator keys, not SSH keys:

keys/validators/validator-1/key.pem - Validator 1 private key
keys/validators/validator-1/pubkey.pem - Validator 1 public key
keys/validators/validator-2/key.pem - Validator 2 private key
keys/validators/validator-2/pubkey.pem - Validator 2 public key
keys/validators/validator-3/key.pem - Validator 3 private key
keys/validators/validator-3/pubkey.pem - Validator 3 public key
keys/validators/validator-4/key.pem - Validator 4 private key
keys/validators/validator-4/pubkey.pem - Validator 4 public key

Purpose: These are used for Besu validator node authentication, not for SSH access.

2. SSH Keys on Nginx Proxy

Location: ~/.ssh/ on Nginx proxy (20.160.58.99)

Found:

~/.ssh/id_rsa.pub - Public key (exists)
~/.ssh/id_rsa - Private key (NOT FOUND - missing)

Status:

✅ Public key exists
❌ Private key missing (this is why SSH from Nginx proxy to backend VMs fails)

3. SSH Keys in Project Directory

Location: Project root

Found: None

Issue Identified

The Nginx proxy has the public key (id_rsa.pub) but is missing the private key (id_rsa). This is why:

SSH connections from Nginx proxy to backend VMs fail with "Permission denied (publickey)"
The public key cannot be used to authenticate without the matching private key

Solutions

Option 1: Generate New SSH Key Pair on Nginx Proxy

# SSH to Nginx proxy
ssh besuadmin@20.160.58.99

# Generate new key pair
ssh-keygen -t rsa -b 4096 -f ~/.ssh/id_rsa -N ""

# Copy public key to backend VMs
for IP in 10.1.1.4 10.2.1.4 10.3.1.4 10.4.1.4 10.5.1.4; do
  ssh-copy-id -o StrictHostKeyChecking=no besuadmin@$IP
done

Option 2: Copy Private Key from Local Machine

If you have the private key on your local machine:

# Copy private key to Nginx proxy
scp ~/.ssh/id_rsa besuadmin@20.160.58.99:~/.ssh/id_rsa
ssh besuadmin@20.160.58.99 "chmod 600 ~/.ssh/id_rsa"

Option 3: Use Azure Run Command to Add Public Key

Since we have the public key, we can add it to backend VMs using Azure Run Command (once it's working):

PUBLIC_KEY=$(ssh besuadmin@20.160.58.99 "cat ~/.ssh/id_rsa.pub")
# Then add to each VM's authorized_keys via Azure Run Command

Validator Keys

The .pem files in keys/validators/ are Besu validator keys, not SSH keys. They are used for:

Validator node authentication in the Besu network
Signing blocks and transactions
Not for SSH access to VMs
