Probably you execute quite a lot of sudo<\/code> commands because you don’t want to sudo su<\/code> and execute commands as root all the time. However, it can be not very pleasant having to keep entering the sudo<\/code> password. So here’s how you can deal with it.<\/p>\n\n\n\n

You noticed that if you execute one and then another one within a few minutes, the 2nd time, you don’t get the message like: [sudo] password for your_username. However, you get it when there is more time between the execution of the two commands.<\/p>\n\n\n\n

How Can I Make sudo Last Longer?<\/h2>\n\n\n\n

The behavior of sudo<\/code> is configured in the “\/etc\/sudoers<\/em><\/strong>” file, and by default timeout of the sudo<\/code> command is 15 minutes<\/strong>.<\/p>\n\n\n\n

The “\/etc\/sudoers<\/em>” file has a timestamp_timeout<\/strong><\/code> option responsible for reprompting the user for a password<\/a> after a specific amount of time.<\/p>\n\n\n\n

The good news is that you can increase this number to a larger one (in minutes) by adding a string in the “\/etc\/sudoers<\/em>” file. After that time, sudo<\/code> will ask for a password again.<\/p>\n\n\n\n

The sudo<\/code> command doesn’t remember your password, but when you first authorize it, a session is created which lasts for timestamp_timeout<\/code>. It stores timestamp<\/a> under the “\/var\/run\/sudo\/ts\/<\/em>” directory.<\/p>\n\n\n\n

It’s essential to make sure you edit your sudoers<\/code> file using visudo<\/code>, which checks your syntax and will not leave you with the wrong configuration and inaccessible sudo<\/code>.<\/p>\n\n\n\n

In other words, running sudo visudo<\/code> instead of editing the file directly causes the system to validate the “\/etc\/sudoers<\/em>” file before it commits the changes.<\/p>\n\n\n\n

To make the sudo<\/code> command last longer, run the following command in terminal:<\/p>\n\n\n

sudo visudo<\/code><\/span><\/pre>\n\n\n
<\/div>\n\n\n\n
Find the lines starting with “Defaults<\/em>” and add “Defaults timestamp_timeout=x<\/em>” where “x<\/em>” is the number of minutes you want between reprompts. In our case, we set this value to 60.<\/p>\n\n\n\n
\"Make<\/a><\/figure>\n\n\n\n
That’s it. Save the file and exit. The sudo<\/code> password prompt will time out after an hour (60 minutes) once sudo<\/code> is invoked by a user.<\/p>\n\n\n\n
In addition, if you specify 0<\/code>, you will always be asked for the password. Keep in mind that if you set a negative value, for example, -1<\/code>, the timeout will never expire.<\/p>\n\n\n\n
Of course, specifying a negative value is not recommended<\/strong> and should be treated as a bad security practice<\/strong>.<\/p>\n\n\n\n
