SSH Tunneling with Wireshark Part 4

SSH tunneling is a technique used to securely transfer data between two networks. Wireshark is a network protocol analyzer that allows you to capture and analyze network traffic.

To use Wireshark with SSH tunneling, you can follow these steps:

1. Establish an SSH connection with tunneling enabled. You can do this by using the -L option followed by the local port and the remote server and port you want to connect to.

For example, if you want to connect to a remote MySQL server on port 3306, you can use the following command:

ssh -L 3306:localhost:3306 user@remote_server

This command will forward all traffic sent to the local port 3306 to the remote server's port 3306.

2. Start Wireshark and select the network interface that corresponds to the local port you specified in the previous step.

3. Start capturing network traffic by clicking the "Start" button in Wireshark.

4. Connect to the remote service as you normally would, using the local port as the destination.

For example, if you want to connect to the MySQL server, you can use the following command:

mysql -h localhost -P 3306 -u username -p

5. Wireshark will capture all the network traffic sent and received during the SSH tunneling session. You can analyze this traffic to troubleshoot any issues or to gain insights into the protocol being used.

Note that SSH tunneling encrypts the traffic between the local and remote systems, so the traffic captured by Wireshark will be encrypted. To decrypt the traffic, you will need to have the private key used in the SSH connection.
