![]() When you're back in it should let you start sniffing without any fuss about being root. Run this: sudo adduser $USER wiresharkĪnd restart or log out. Then you just need to add the user to that group. Technically any person with access to a computer logged in with a wireshark account will be able to sniff. If the 'ubuntu' user is in the sudoers file, you can use the command sudo su. The command su - root makes you become the superuser in order to do so, you have to enter the superusers password. It is normally not accessible by non-privileged users ('ubuntu' in your case). This is obviously more secure than just letting anybody sniff but does mean there's no password checking. The /root directory is /root, and is the superusers home directory. Anybody in that group will be able to sniff without being root. That's what we're aiming for, so select Yes and hit return. This will ask you if you want to allow non-root user to be able to sniff. In a terminal (very important that you're in a terminal, not just the Alt+F2 dialogue) run this: sudo dpkg-reconfigure wireshark-common The bit that normally needs root is the packet collection application and this can be configured to allow certain people to use it without sudo, gksu, etc. For example, when there is only one user account registered on the system, or when an automated script requires elevated privileges to perform certain tasks.For WireShark there's a better way. ![]() In some cases, it may be useful to disable this mechanism. Running sudo su without a passwordīy default, a command run with sudo requires that the user authenticates themselves using their own password. Note that the sudo -su command differs from sudo su - in the sense that the su expression will be treated as option flags of the sudo command, where the -s flag is used to run a new shell, and the -u flag is used to run a command as a user different from root. If the password is correct, you should have a prompt showing ‘roothostname’. This should prompt you for a password, enter your root password. Then type the command ‘sudo su’ and press enter. Change the current directory to the user’s home directory.ĭon’t confuse sudo -su with sudo su -! To open the root terminal in Kali Linux, first open the terminal window.Initializes the environment variables HOME, SHELL, USER, LOGNAME and PATH.Clear all the environment variables except for TERM.Since the root account is disabled by default on most Linux distributions -which means that the root password is not set, in order to prevent anyone from directly logging into it-using the su command alone will certainly result in an authentication error with a message like su: Authentication failure: When called with no user specified, the su command will attempt to run an interactive shell as root, prompting you to enter the root password. Spawning a root shell with the su command In this article, we’ll explain why these two commands are often combined together in order to access a root shell, and how to run sudo commands without having to type in the user password. sudo resides in the fact that the su command gives access to an interactive shell session, whereas the sudo command only allows to execute one command at a time. Like the sudo command, it is generally used to execute commands as the superuser (also known as the "root" user). In Unix-like operating systems, the su command is used to temporarily log into another user account and execute commands using its privileges.
