Can you run a sudo command without a password?
A better solution if you want to run something with sudo without putting in your password is to allow your user to do exactly that one command without password. And no password will be requested. Thanks for contributing an answer to Unix & Linux Stack Exchange!
Why does Sudo ask for the root password?
To add to Archemar’s answer, sudo asks for the password of the user running sudo, not the user the command will be run as. You say that the ‘admin’ and ‘root’ accounts are ‘linked’ and share the same password.
Why do I need Sudo to run SSH?
Both these accounts are linked somehow because they share the same password. During an SSH session as admin, ‘sudo’ is required to run commands, unless I switch to the user ‘root’. I have some services on which I need to run now and then, or even at system startup.
Can a sudo command be executed with a TouchID?
If you have come to this conclusion based on sudo accepting the password for the ‘admin’ account (and the password sudo accepts changing when the password for ‘admin’ is changed), this is normal behaviour for sudo. If you are using a MacBook with TouchID, you can configure SSH sudo with Mac TouchID (fingerprint, 2FA)
How long does it take for sudo to ask for password?
When you run a command with sudo, it asks for your account’s password. The default timeout for the password is 15 minutes (in Ubuntu Linux). Which means that you’ll have to enter the password again if you run a command with sudo after fifteen minutes.
How long does it take to run sudo command in Fedora?
Most Linux distributions like Ubuntu, Debian, Fedora use the sudo mechanism to allow admin users to run commands with root privileges. When you run a command with sudo, it asks for your account’s password. The default timeout for the password is 15 minutes (in Ubuntu Linux).
How to run Sudo as a user other than root?
Run the command as a user other than the default target user (usually root). The user may be either a user name or a numeric user ID (UID) prefixed with the ‘#’ character (e.g. #0 for UID 0).
The difference is that every user in the system will be able to run a setuid command, even without being in the sudoers file. Also, obviously, you won’t need to prefix the command with sudo. You need the “NOPASSWD” tag.
What does Sudo stand for in Linux system?
sudo (“superuser do”) is nothing but a tool for Linux or Unix-like systems to run commands/programs as another user. Typically as a root user or another user.
