How do I adjust the settings when the SSH connection times out in the Data Connector?

When the SSH connection times out in the Data Connector, you can adjust the settings through the following steps:

1. Check Network Stability

A poor network is a common cause of SSH connection timeouts. Ensure that your local network environment is stable. You can try to switch to a different network, such as from Wi - Fi to a wired network, or use a mobile hotspot.

2. Modify SSH Server Configuration

If you have access to the SSH server, you can modify its configuration file to extend the timeout time.

  • Locate the SSH server configuration file, usually named sshd_config. On most Linux systems, it is located in the /etc/ssh/ directory.
  • Open the file with a text editor, for example:
sudo nano /etc/ssh/sshd_config
  • Add or modify the following parameters:
ClientAliveInterval 60
ClientAliveCountMax 3

- `ClientAliveInterval` sets the time interval (in seconds) for the SSH server to send a keep - alive message to the client. In this example, it is set to 60 seconds.
- `ClientAliveCountMax` sets the maximum number of keep - alive messages that the server can send without receiving a response from the client before disconnecting. Here, it is set to 3. So, if the server does not receive a response from the client for 3 consecutive 60 - second intervals, it will disconnect the SSH connection.
  • Save the changes and exit the text editor. Then restart the SSH service:
sudo systemctl restart sshd

3. Adjust SSH Client Configuration

You can also adjust the settings on the SSH client side.

  • For OpenSSH clients (commonly used on Linux and macOS), you can edit the ~/.ssh/config file. If the file does not exist, you can create it.
nano ~/.ssh/config
  • Add the following content for the specific host:
Host your_server_ip_or_hostname
    ServerAliveInterval 60
    ServerAliveCountMax 3

- `ServerAliveInterval` is similar to `ClientAliveInterval` on the server side, which sets the time interval for the client to send a keep - alive message to the server.
- `ServerAliveCountMax` is similar to `ClientAliveCountMax` on the server side.
  • Save the file. The next time you connect to the server using SSH, these settings will take effect.

In the context of cloud services

If you are using a Data Connector in a cloud environment and encounter SSH timeout issues, consider using Tencent Cloud's Cloud Monitor service. It can help you monitor the network status and performance of your cloud resources. By setting up alarms in Cloud Monitor, you can be notified in a timely manner when there are network anomalies, which is conducive to quickly locating and solving problems.
