Here are some steps you can take to troubleshoot and resolve this issue:

1. Check Server Configuration

Ensure that the server linux01 is up and running and that it is reachable from the machine where Magento is installed.

• Ping the Server: Open a terminal and run ping linux01 to see if the server responds.
• Check SSH Connection: Try to SSH into the server using ssh username@linux01 to verify that you can connect.

2. Verify Firewall Settings

Ensure that the firewall on the server is not blocking the connection.

• Check Firewall Rules: Use iptables or any other firewall management tool to check if any rules are blocking the connection to the required ports.

3. Validate Magento Configuration

Ensure that the connection details in Magento's configuration are correct.

• Local.xml: Check the app/etc/local.xml file to ensure that the database connection settings are correct.
• Host Entry: Make sure linux01 is correctly resolved in your /etc/hosts file or DNS.

4. Check Web Server Configuration

Ensure that your web server (Apache, Nginx, etc.) is properly configured to serve the Magento site.

• Virtual Hosts Configuration: Check the virtual host configuration for any misconfiguration.
• Logs: Review the web server logs for any errors related to the connection.

5. Debugging Steps

If the above steps don't resolve the issue, you can enable debugging to get more detailed error messages.

• Enable Error Reporting: Edit the index.php file in the Magento root directory and set ini_set('display_errors', 1); and error_reporting(E_ALL); to enable error reporting.
• Check Logs: Review the var/log/system.log and var/log/exception.log files for any specific error messages.

6. Check PHP Configuration

Ensure that the PHP configuration allows connections to the server.

• PHP Extensions: Ensure that all required PHP extensions (such as cURL, pdo_mysql) are installed and enabled.
• php.ini: Check the php.ini file for any restrictions that might be blocking the connection.

7. Server Resources

Ensure that the server has enough resources (memory, CPU, etc.) to handle the connection.

Example Troubleshooting Commands

Ping: ping linux01

SSH: ssh username@linux01

Firewall Rules: sudo iptables -L

Web Server Logs: tail -f /var/log/apache2/error.log or tail -f /var/log/nginx/error.log

It sounds like there might be an issue with your server configuration or network settings. Here are a few things you can check:

1. Server Hostname: Ensure that "linux01" is correctly resolving to the appropriate IP address. You might want to try pinging "linux01" from your server to see if it resolves correctly.

2. Firewall and Ports: Verify that your firewall settings aren't blocking the connection. Ensure that the necessary ports for Magento's Connection Manager are open.

3. Permissions: Check if the user you're logging in with has the necessary permissions to access the server.

4. Server Configuration: Double-check your server’s configuration files (e.g., hosts, httpd.conf, or nginx.conf) to ensure everything is set up correctly.

5. Magento Logs: Review Magento's logs in var/log/ for any additional error messages that might give more insight into what’s going wrong.

If all else fails, try reaching out to your hosting provider to see if there are any issues on their end. Good luck!

It looks like you’re facing a connectivity issue with Magento 1.9.1. The "Cannot connect to host: linux01" message suggests a problem with reaching the specified host. Check if linux01 is accessible from your server using tools like ping or telnet. Verify your connection credentials for accuracy and ensure there are no network or firewall issues blocking the connection. Reviewing server and Magento logs can provide additional clues. Also, ensure that PHP configurations and services are properly set up and consider restarting your web and database servers, for details click here

This issue may be due to incorrect host settings or firewall restrictions. Check the server configuration, ensure correct credentials, and verify firewall/port access for the host.
