  • 1.  Sudo Logging after sudo to a user

    Posted Thu August 19, 2021 01:03 PM
    Hello everyone,

    I have done a fair bit of research and everything I am running onto says to place log_output and log_input into the sudoers file to capture what is run after a users sudo's to another user.  It is creating the /var/log/sudo-io directory structure and sudoreplay gives just generic log information as I am used to seeing, only showing the "sudo su -" command.  Is there a feature in sudo that will allow auditing of what a user does after they "sudo su -"?  If so could you provide any guidance on the subject, maybe I am just missing a key step.

    Thanks,
    Justin

    Hi Justin

    I read the following on the sudo user mailing list:
    https://www.sudo.ws/mailman/listinfo/sudo-users

    Once you run a shell sudo cannot log the individual commands you run. If you have log_output enabled you can see the output of the session, including the commands run, but the individual commands are not logged separately. You can, however, use sudo to run commands as another user directly. E.g. sudo -u other_user command.

    You will only see commands logged when you type "sudo <cmd>". As when you do "sudo su -", it creates a new shell and all the other commands won't be in the sudo log.  You might be able to find the commands in root's history.

    I've only seen logging like that in tools like PowerBroker. Sudo
    only logs the command.

    You need to use sudoreplay to see the logs
