Ubuntu
sudo package

How come the following sudo command does not prompt for the password anymore?

Asked by chiao woei

I noticed lately that when i issued a sudo command the first time, it will asked me for my password but the following command will not. I also read from somewhere that there is a grace period but the funny thing is that closing the current terminal window and running again the sudo command in a new window also will not reasked me for the password. I also recalled that this wasn't the case previously. Btw, for your informations, the last couple of changes that i made were to installed apache2, php and mysql and i also change my root password.
Will this compromised my security?

Hello,

https://help.ubuntu.com/community/RootSudo

The password is stored by default for 15 minutes. After that time, you will need to enter your password again.

Hello,
Applications>Accessories>Terminal
sudo visudo

Then add/change the following line:

Defaults !lecture,tty_tickets,!fqdn

with

Defaults !lecture,tty_tickets,!fqdn,timestamp_timeout=2

The 2 being whatever time you want, in minutes.

Thank you williamts99. Yes, you solved my problem. But i still got one
statement to made. I change the timeout value to 1 minute and then i did
a test by checking the clock on the system tray. I noticed that it is
not very accurate. Is this normal friend?

I'm not sure about that, I have only used the default and disabled completely, how close to a minute was it?

around 3 minutes. To be more precise i will need to use a stopwatch.
Anyway, thank again for your help...

BYE

If you are running more sudo commands in between, it will reset the timer.
