What is vc 1 in securetty

Connect and share knowledge within a single location that is structured and easy to search. Specifically, what is the end result of adding and removing each entry type? My understanding is that they affect how and when you can login, but are there any other effects? And when can you and when can you not login depending on which entries are there?

What I do know is that tty correspond to whether you can login from the first 6 consoles that you reach using Ctrl - Alt - F1 through Ctrl - Alt - F6. I always thought those were virtual consoles, so I'm a bit confused. And what does console correspond to?

So, only the login program is affected by default. You could add a line to do so, but ssh doesn't set the actual tty until sometime after the auth stage, so it doesn't work as expected. The above answer is based on RHEL 5. Many other forums, blogs, etc online have inaccurate and incomplete information in this topic as well, so I've done extensive research and testing to try to get the correct details.

If anything I've said is wrong, please let me know though. And when can you and when can you not login depending on which entries are there? What I do know is that tty correspond to whether you can login from the first 6 consoles that you reach using Ctrl — Alt — F1 through Ctrl — Alt — F6.
