![]() Please let us know if you have any feedback about this page. The more scoring criteria a new password meets, the higher its score and derived complexity. It also needs to meet 3 (or more) of the following scoring criteria: ![]() Octopus applies a scoring system to a new password to decide if it meets the complexity rules. Passwords in Octopus must meet password complexity rules. When Active Directory authentication is in use, the -password argument is not required: service - stop admin - username = YOURUSERNAME service - start Password complexity Replace YOURUSERNAME with the simple login name of the administrator account, and provide the new password. For username/password authentication service - stop admin - username = YOURUSERNAME - password = YOURPASSWORD service - start To reset the password of an administrator, or to make a user into an administrator, open an administrative command prompt on the Octopus Server and run the following commands. Users can be made administrators, and new administrator accounts created using the command line on the Octopus Server machine. Select the user whose password you want to change:Įnter and confirm the new password, then click Save: Octopus Server administrators can reset the passwords of other users from the Octopus Web Portal at Configuration ➜ Users. To change your password, select Change password:Įnter and confirm your new password, then click Save: Select Profile to go to your profile page. Disable the root account to avoid broad permission escalation, and use the sudo command and a well-tended sudoers file to manage who can manage your computers.In the Octopus Web UI, click your username in the top right corner of the screen. The sudoers file provides example syntax, but here's an example of allowing all users in the Unix group softadmins to run all commands in the sudoer alias SOFTWARE: # Installation and management of softwareĬmnd_Alias SOFTWARE = /usr/bin/dnf, /usr/bin/rpmĮverything from mission-critical machines to computers with customer data, and even your own humble personal laptop, are too important to casually lend the keys out to anyone who needs an escalation of privilege. You could have, for instance, an admin group that could use commands such as useradd, groupadd, and usermod, and a software group that could use commands like dnf and rpm. You can create aliases in the sudoers file to group hosts, commands, and users together. Sorry, user bogan is not allowed to execute '/bin/ls'Īs root on. Test it out by switching to that user's account and running the command: $ su - shadowman # Allow root to run any commands anywhere # The COMMANDS section may have other options added to it. # which machines (the sudoers file can be shared between multiple For instance, to permit the user shadowman to run the groupadd command: # Next comes the main part: which users can run what software on The visudo command assumes you want to edit text with vi but also allows you to override that default by setting the variable EDITOR: $ sudo EDITOR=nano visudoįind the section of the sudoers file defining command permissions, and add the user and command you want to allow. To grant selective privileges to a single command or a group of commands, edit /etc/sudoers with the visudo command. You just want to allow them to create new groups. You don't want to give this user permission to do any administrative task. Suppose you want to grant a user permission to run a specific application, such as the groupadd command, that usually requires administrative permissions. The problem with this approach is that a sysadmin must choose between handing over the master key to the system and withholding the key and all control of the system. ![]() ![]() If you don't have the password, you have no admin power. As is the Linux standard, you won't see any characters on screen while entering this password. After this, enter your new password twice, pressing Enter after each entry. If you have the password for root, you get all the power. passwd When you press the Enter key, the system will prompt you to confirm your current password. The su command uses an all-or-nothing model.
