## Mapping Network

Understanding the landscape through network mapping is a crucial phase in the eLearnSecurity Junior Penetration Tester (eJPT) certification.

#### Wireshark

Dive into network traffic analysis with:

```bash
sudo wireshark # Launch Wireshark for detailed network traffic analysis
```

#### ARP Scan

Identify hosts on the network using:

```bash
sudo arp-scan -I eth0 -g 10.0.2.15/24 # Perform ARP scan to discover hosts
```

#### Ping Hosts

Confirm the availability of a host:

```bash
ping 10.0.2.15 # Ping a host to check for its availability
```

#### Fping Network

Ping all hosts within the netmask:

```bash
fping -I -g 10.0.2.0/24 # Ping all hosts within the specified netmask
```

## Port Scanning

Efficient port scanning is a fundamental skill for penetration testers.

#### Nmap Scan

Scan hosts for open ports:

```bash
sudo nmap -sn 10.0.2.0/24 # Perform a quick scan to identify live hosts
```

### Nmap Scan from List

Scan open ports for hosts listed in a file:

```bash
sudo nmap -iL IPs.txt # Perform port scanning for hosts listed in the file IPs.txt
```

#### Service and OS Detection

Enhance your scan with service and OS detection:

```bash
sudo nmap -iL IPs.txt -sV -O # Conduct an in-depth scan with service and OS detection
```

#### TFTP Connection

Connect to FTP if it's open:

```bash
tftp 10.10.10.10 -p 143 # Connect to FTP server using TFTP protocol
```

#### Aggressive UDP Scan

Run an aggressive scan with basic scripts:

```bash
nmap 10.10.10.10 -T4 -sU -p 161 -A # Perform an aggressive UDP scan with detailed information
```

Explore these commands to master the art of footprinting and scanning, an integral part of the eJPT certification.
