[Solved] GNU Screen / how to lock AND detach

postmanpat · 2019-07-29 13:14:46

Hi every one,

I use GNU Screen:
https://wiki.archlinux.org/index.php/GNU_Screen

A screen can be lock with the binding: C-a x
which is convinient for example to have a screen session for root activities.

I would like to be able to lock and detach from a screen session (I tried c-a x, c-a d without success)
However, I have not figured out how to detach from the session after the latter has been locked.

Have a nice summer.

FTR, lockscreen is badly named. It doesn't lock the screen session, it detaches the session and locks the current terminal.

See https://www.gnu.org/software/screen/man … /Lock.html

Thanks WorMzy for your reply and the link,

I find it curious that Screen only detaches the session.
I just need to open a new terminal and attach to the detached session to bypass the lock... (!!)

I should maybe mark this thread as solved since you answered the question.
However, if anybody find some kind of hack, let us know.

Thank you again and take care.

Hello,

The Gnu Screen's function I was looking for was 'password'.
1) To password protect a session:
C-a :password
and type twice the password you want to use

2) If you want to remove any password from the session:
C-a :password ""

3) If you want to protect all your screen session with the same password.
- Create a new session: screen -S toto
- Protect the session: C-a :password and type twice your choosen password
- Paste the encrypted password in the current buffer: C-a ]
- Write encrypted password in your ~/.screenrc by adding the line: password <encryptedpassword>
