Lab exercise

The steps to capture the normal TCP connection flow (a sample program is provided as part of this book) are as follows:

Open Wireshark, start capturing the packets, and choose display filter tcp.port==8082.
Compile the Java program TCPServer01.java using the javac command:
```
bash$ ~ javac TCPServer01.java
```
Run TCPServer01 using the java command:
```
bash$ ~ java TCPServer01
```

Verify the server is listening on port 8082:

bash$ ~ netstat -an | grep 8082
tcp46      0      0  *.8082                 *.* LISTEN

Compile the client program Client0301.java using the javac command:
```
bash$ ~ javac Client0301.java 
```
Run the client program:
```
bash$ ~ java Client0301
```
View and analyze the packet in Wireshark.
