### **The Ultimate CLI Muscle Memory Training Plan**  
*(For Nerds Who Want to Achieve Cloud Networking CLI Mastery Fast)*  

---

### **1. The Setup: Build a Home Lab That Mimics Production**  
#### **Hardware (Bare Minimum)**  
- **Proxmox Server** (or any hypervisor) – Run nested VMs/containers.  
- **MicroPC/Raspberry Pi** – For low-power networking (BGP, VPNs).  
- **Spare Laptop** – As a jump host/terminal.  

#### **Software Stack**  
| Tool               | Purpose                                  | Install Command                          |  
|--------------------|------------------------------------------|------------------------------------------|  
| **AWS CLI v2**     | Cloud-native networking                  | `curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" && unzip awscliv2.zip && sudo ./aws/install` |  
| **Terraform**      | IaC for repeatable labs                  | `sudo apt-get install terraform`         |  
| **FRRouting**      | BGP/OSPF practice                        | `sudo apt-get install frr`               |  
| **WireGuard**      | VPN tunneling                            | `sudo apt-get install wireguard`         |  
| **tcpdump**        | Packet-level debugging                   | `sudo apt-get install tcpdump`           |  
| **jq**            | JSON parsing for AWS CLI outputs         | `sudo apt-get install jq`                |  
| **Tmux**          | Terminal multiplexing for drills         | `sudo apt-get install tmux`              |

### **2. The Drills: Daily CLI Workouts**  
*(30-60 mins/day, designed for muscle memory)*  

#### **Drill 1: AWS Networking Speed Run (15 mins)**  
**Goal**: Automate VPC creation + troubleshoot.  
```bash
# Create a VPC with Terraform (save as `vpc.tf`)
resource "aws_vpc" "lab" {
  cidr_block = "10.0.0.0/16"
  tags = { Name = "cli-muscle-memory" }
}

# Deploy and debug
terraform init && terraform apply -auto-approve
aws ec2 describe-vpcs --query 'Vpcs[].CidrBlock' | jq
aws ec2 delete-vpc --vpc-id $(aws ec2 describe-vpcs --query 'Vpcs[?Tags[?Key==`Name` && Value==`cli-muscle-memory`]].VpcId' --output text)
```
**Pro Tip**: Time yourself. Aim for <2 mins by Day 7.

---

#### **Drill 2: BGP + VPN Chaos (20 mins)**  
**Goal**: Simulate hybrid cloud failures.  
1. **Set Up FRRouting (BGP) on a Linux VM**:  
   ```bash
   sudo vtysh
   configure terminal
   router bgp 65001
    neighbor 192.168.1.1 remote-as 65002
    timers bgp 10 30  # Aggressive timers for failure sim
   ```
2. **Break It**:  
   ```bash
   sudo ifconfig eth0 down  # Kill primary interface
   ```
3. **Fix It**:  
   ```bash
   show ip bgp summary  # Diagnose
   sudo ifconfig eth0 up && sudo systemctl restart frr
   ```

---

#### **Drill 3: Packet Kung Fu (10 mins)**  
**Goal**: Diagnose HTTPS failures without logs.  
```bash
# Capture TLS handshake failures
sudo tcpdump -i any 'tcp port 443 and (tcp-syn|tcp-ack)!=0' -nnvv -w tls.pcap

# Analyze in Wireshark (or CLI):
tshark -r tls.pcap -Y 'ssl.handshake.type == 1'  # Find failed handshakes
```

---

#### **Drill 4: Cost-Ops Reflex Training (15 mins)**  
**Goal**: Find and nuke wasteful resources.  
```bash
# Find untagged EC2 instances
aws ec2 describe-instances --query 'Reservations[].Instances[?!not_null(Tags[?Key==`Owner`])].InstanceId' | jq

# Terminate with prejudice
aws ec2 terminate-instances --instance-ids $(aws ec2 describe-instances --query 'Reservations[].Instances[?!not_null(Tags[?Key==`Owner`])].InstanceId' --output text)

# Find idle NAT Gateways
aws ec2 describe-nat-gateways --filter Name=state,Values=available --query 'NatGateways[?NetworkInterfaces[0].Status!=`in-use`].NatGatewayId' | jq
```

---

### **3. The Gauntlet: Weekly Challenges**  
*(Simulate real outages—no Google allowed!)*  

#### **Challenge 1: "The Silent NACL"**  
- **Scenario**: All traffic to `TCP/443` is blocked, but Security Groups are open.  
- **Tools Allowed**: Only `tcpdump`, `aws ec2 describe-network-acls`.  
- **Fix Time**: <10 mins.  

#### **Challenge 2: "BGP Route Leak"**  
- **Scenario**: Your VM can’t reach the internet, but `ping 8.8.8.8` works.  
- **Tools Allowed**: `vtysh`, `ip route`.  
- **Fix Time**: <15 mins.

### **4. Pro Tips for CLI Dominance**  
1. **Alias Everything**:  
   ```bash
   alias aws-vpcs='aws ec2 describe-vpcs --query "Vpcs[*].{ID:VpcId,CIDR:CidrBlock}" --output table'
   alias kill-nats='aws ec2 describe-nat-gateways --query "NatGateways[?NetworkInterfaces[0].Status!=\`in-use\`].NatGatewayId" --output text | xargs -I {} aws ec2 delete-nat-gateway --nat-gateway-id {}'
   ```
2. **CLI-Only Days**:  
   - Spend 1 day/week **without a GUI** (AWS Console, Wireshark, etc.).  
3. **Keybindings**:  
   - Master `Ctrl+R` (reverse search), `Ctrl+A/E` (line navigation).

### **5. Measure Your Progress**  
| **Skill**               | **Beginner**                     | **Master**                              |  
|-------------------------|-----------------------------------|-----------------------------------------|  
| **VPC Creation**        | 3+ mins (manual clicks)          | <60 secs (CLI/Terraform)                |  
| **BGP Troubleshooting** | Relies on logs                   | `tcpdump + vtysh` in <5 mins            |  
| **Cost Hunting**        | Manual Cost Explorer             | One-liner to find waste                 |  

---

### **Final Wisdom**  
- **Repetition > Theory**: Do each drill **3x/week** until it’s boring.  
- **Break Things Intentionally**: Corrupt BGP tables, drop packets, then fix.  
- **Automate Your Punishment**: Write scripts that **break your lab nightly**, forcing you to debug.
