# Server Inspection Reference
|
|
|
|
When asked to inspect a server without a URL, assume the **local machine Hermes runs on**.
|
|
|
|
## Quick Checklist
|
|
|
|
### System Resources
|
|
```bash
|
|
# CPU, load, uptime
|
|
uptime && top -bn1 | head -3 && nproc
|
|
|
|
# Memory
|
|
free -h
|
|
|
|
# Disk
|
|
df -h
|
|
```
|
|
|
|
### Running Services & Processes
|
|
```bash
|
|
# All listening ports
|
|
ss -tlnp | grep LISTEN
|
|
|
|
# Top processes by CPU
|
|
ps aux --sort=-%cpu | head -10
|
|
|
|
# Docker containers
|
|
docker ps -a
|
|
```
|
|
|
|
### Service Manager
|
|
```bash
|
|
systemctl list-units --type=service | grep running
|
|
# or
|
|
service --status-all
|
|
```
|
|
|
|
### Network
|
|
```bash
|
|
# All LISTEN ports (not just common ones)
|
|
ss -tlnp
|
|
|
|
# DNS resolution test
|
|
nslookup example.com
|
|
```
|
|
|
|
### Security
|
|
```bash
|
|
# fail2ban status
|
|
fail2ban-client status
|
|
|
|
# UFW firewall (if enabled)
|
|
ufw status
|
|
```
|
|
|
|
## Scope Signals
|
|
|
|
| User says | Means |
|
|
|-----------|-------|
|
|
| "服务器巡检" / "server inspection" | Local machine (no URL given) |
|
|
| "巡检 ephron.ren" | Remote web service at that domain |
|
|
| "check the service on port 8000" | Likely remote host:port |
|
|
| "你的服务器" / "this machine" | Local machine explicitly |
|
|
|
|
## Anti-Patterns
|
|
|
|
- **Don't** default to checking remote web services when no URL is provided
|
|
- **Don't** assume the remote service is on the same machine as Hermes
|
|
- **Do** ask for clarification if "server" could mean local or remote
