In my job as a Linux System Administrator, a considerable amount of the support requests that I receive are related to SSH problems. <\/p>\n\n\n\n
Given this, I created a Python script that checks the most common reasons the ssh-client might not be working correctly. It creates a report and allows the user to fix those problems by pressing a button. <\/p>\n\n\n\n
The idea is to create a tool that can do a diagnosis of the ssh-problems of a Linux user. In case of problems the tool will allow the person to fix the issues with one click.<\/p>\n\n\n\n
On top of that, I also wanted to practice:<\/p>\n\n\n\n
Client-side ssh problems are usually related to: <\/p>\n\n\n\n
1. Bad private ssh-key permissions: Keys should be 400, 600 or 700, nothing more. <\/p>\n\n\n\n
2. Problems with the user’s ssh folder permissions (\/home\/user\/.ssh\/): It should be 700.<\/p>\n\n\n\n
3. Problems with the user’s home folder permissions (\/home\/user): It should be 755.<\/p>\n\n\n\n
4. Problems with the home folder permissions (\/home\/): It should be 755.<\/p>\n\n\n\n
5. A problem in the content of an ssh key because someone manipulated (by mistake probably)<\/p>\n\n\n\n
