Fix SSH Auto Exit Caused by sudo Command in Shared Hosting

Running restricted sudo commands in shared hosting can cause SSH sessions to exit immediately.

Solution:

  1. Access .bash_history: Log in using ssh user@host bash or the hosting panel's file manager.
  2. Edit History: Remove the problematic sudo command from .bash_history.
// other code
sudo ... // remove this line
Enter fullscreen mode Exit fullscreen mode
  1. Save and Retry: Save changes and log in normally.

Explanation:

Shared hosting environments restrict sudo commands to maintain security and stability. Running such commands can conflict with server configurations, causing unexpected behavior like session exits. By editing .bash_history to remove the command, you prevent the system from re-triggering the issue during login.

Tips:

Avoid Restricted Commands: Don't run sudo or similar commands in shared hosting unless explicitly permitted.
Use the Hosting Panel: If SSH fails, the hosting panel's file manager is often a good alternative for accessing and editing files.
Contact Your Host: For administrative tasks, reach out to your hosting provider instead of attempting restricted actions.
Backup Critical Files: Before making changes, back up important files to avoid accidental loss.

By understanding shared hosting restrictions and troubleshooting effectively, you can maintain seamless access and avoid disruptions.
