All checks were successful
- Add curl example for localhost RPC endpoint (127.0.0.1:8006/rpc/head) - Add RPC access examples for aitbc1 (localhost and aitbc hostname) - Create Important Notes section with SSH best practices - Document localhost command execution (no SSH needed) - Add guidance on proper quoting and connectivity testing

SSH Access Patterns for AITBC Nodes
Purpose
Document SSH access patterns for all AITBC nodes in the infrastructure.
Node Access Patterns
aitbc (localhost)
Direct access - no SSH required.
# Run commands directly on localhost
echo "command"
systemctl restart service-name
curl http://127.0.0.1:8006/rpc/head
aitbc1
Direct SSH access.
ssh aitbc1
# Or execute single command
ssh aitbc1 "command"
# Access aitbc1's blockchain RPC
ssh aitbc1 "curl http://127.0.0.1:8006/rpc/head"
# Access aitbc from aitbc1
ssh aitbc1 "curl http://aitbc:8006/rpc/head"
gitea-runner (hosts aitbc2 blockchain node)
Direct SSH access. The aitbc2 blockchain node runs on this same host.
ssh gitea-runner
# Or execute single command
ssh gitea-runner "command"
# aitbc2 blockchain node runs on this host
# Execute aitbc2-specific commands
ssh gitea-runner "/opt/aitbc/aitbc-cli blockchain info"
ssh gitea-runner "systemctl status aitbc-blockchain-node --no-pager"
Important Notes
- Never SSH to localhost: Commands should run directly on the local machine
- Use proper quoting: When passing commands to SSH, use single quotes to prevent shell expansion
- Test connectivity: Verify RPC endpoints are accessible before running sync operations
Common Operations
Check service status on aitbc1
ssh aitbc1 "systemctl status aitbc-blockchain-node --no-pager"
Restart service on gitea-runner (aitbc2)
ssh gitea-runner "systemctl restart aitbc-blockchain-node"
Copy file to aitbc1
scp /path/to/file aitbc1:/path/to/destination
Execute script on gitea-runner
ssh gitea-runner "bash /path/to/script.sh"
Multi-Node Operations
Run command on all remote nodes
for node in aitbc1 gitea-runner; do
ssh "$node" "systemctl status aitbc-blockchain-node --no-pager"
done
Check block heights across all nodes
for node in aitbc1 gitea-runner; do
echo "=== $node ==="
ssh "$node" "curl -s http://localhost:8006/rpc/bestBlock | jq '.height'"
done
