# Chapter 3: Configuring SecureCRT Connections

Configuring a new session in SecureCRT to connect to a remote host is a crucial step. Below is a detailed guide on how to do so:

### Creating a New Session

To create a new session in SecureCRT, which is establishing a new connection configuration, follow these steps:

1. Open SecureCRT software and click on the "File" menu.
2. Select "New Session" to create a new session.
3. In the pop-up dialog, enter the session name and choose the connection type and protocol (e.g., SSH, Telnet, etc.).
4. Enter the IP address or domain name of the remote host and specify the port number.
5. Configure other session parameters as needed, such as username, password, authentication method, etc.
6. Once you have confirmed that the configuration information is correct, click the "Connect" button to establish the connection.

### Configuring Remote Host Connection Information

When creating a new session, configuring the connection information of the remote host is essential. Here are some common connection parameters:

| Parameter | Description |
|-------------------|-----------------------------------------|
| Hostname/IP Address | The address of the remote host, which can be a domain name or an IP address |
| Port Number | The connection port of the remote host |
| Username | The login username for the remote host |
| Password | The login password for the remote host |
| Authentication Method | Such as password, public key authentication, etc.|

By following these steps and connecting information configuration, you can successfully connect to the remote host and perform operations such as file transfer.
