How is the security affected when nopasswd is set in passwordless Sudo?
Given the facts ssh is done via keys, keys are password protected and all user accounts have passwords (so su bob is impossible without a password): how is the security affected when NOPASSWD is set in the sudo file? NOPASSWD doesn’t have a major impact on security.
Why do I need a Sudo password for Sudo?
A standard user account only has limited privileges and can run only specific commands on the system. The sudo command elevates a standard user account, granting root access to the system. Every time you sudo a sudo command you will be prompted for the sudoer password, which can become repetitive.
How to use passwordless SSH for another username?
1) put user@ into the svn url ; this tells svn+ssh to login as that user. I think it’s kind of a bad idea from a maintenance perspective because things like externals that point at other parts of the repository won’t work correctly.
Can you use Ansible with a Sudo password?
Ansible can use various things for automation: like sudo with a sudo password, or NOPASSWD. Or use su, suexec, doas, or whatever. Just bear in mind that ideally ansible should be used for automation (infra as code), not for interactive use.
Do you need a root password for Sudo Su?
Also, systems that come pre-configured with sudo access typically have the root account disabled (no root password), you can enable that using the passwd command after becoming root via sudo su. It is configurable* but, by default, “sudo” asks you for your password.
Why does Sudo need to verify your identity?
This is why sudo needs to verify your own identity rather than that of the target user. In other words, trying to su to someone you’re not is like attempting to charge your purchases to a stolen credit card while using sudo is like selling your friend’s car by legal proxy.
Which is better to run Su or sudo?
Between su and sudo, when you consider a single user, su is a little more secure in that an attacker who has found your password can’t gain root privileges immediately. But all it takes is for the attacker to find a local root hole (relatively uncommon) or install a trojan and wait for you to run su.
