  • Does usr sbin nologin as a login shell serve a security purpose?
    Security With respect to security, you'll typically see either sbin nologin or sometimes bin false, among other things in that field They both serve the same purpose, but sbin nologin is probably the preferred method In any case they're limiting direct access to a shell as this particular user account
  • debian - How can I su to a user with no login shell? - Unix Linux . . .
    If your user had a login shell, you would need to type in your cmd as: su --shell= bin bash locked or sudo -u locked bin bash, provided the default shell specified for the target user is listed in etc shell (Note that there is an equal sign after the long option --shell ) However: the point of having a user with no login shell is precisely that that user cannot login in any way, be it directly at session start or via another user account Oddly that is exactly what you are trying to
  • Disable a users login without disabling the account
    But we can still able to switch to a user shell from the root account, but not able to switch to user account by other normal users login shell We can also disable account by providing bin nologin or bin false in to etc passwd file So user may not able to login in
  • Can a command be executed over ssh with a nologin user?
    Setting sbin nologin as the user's shell (or bin false or bin true, which are almost equivalent) forbids the user from logging in to run any command whatsoever SSH always invokes the user's login shell to run commands, so you need to set the login shell to one that is able to run some commands There are several restricted shells that allow users to run only a few commands For example rssh and scponly are both such shells that allow the user to run a few predefined commands (such as scp
  • Disable user shell for security reasons - Unix Linux Stack Exchange
    Changing the shell to bin false or usr sbin nologin will only prevent them from running commands on those services that can be used to run commands (console login, ssh, telnet, rlogin, rexec ), so affect authorisation for some services only For ssh for instance, that still allows them to do port forwarding
  • Is it possible to grant users sftp access without shell access? If yes . . .
    Setting the shell of the sftponly users to sbin nologin is neither necessary nor harmful for this solution, because SSH's ForceCommand internal-sftp overrides the user's shell Using sbin nologin may be helpful to stop them logging in via other ways (physical console, samba, etc) though, so it's still recommended
  • Passwordless SSH for System User with NO Login Shell
    You have create an account with nologin shell on that "main" machine For that account you should generate ssh keys which can be used for remote login on machine which should be shutdown nologin shell will prevent login on that account, but it still can be used for remote login on other system To login as user with nologin shell you'll have to use su - user_name -s bin bash My point is that the 'main' machine will automatically shutdown remote servers, without human interaction
  • Can I allow a non-root user to log in when etc nologin exists?
    If your system uses PAM, the login denial when etc nologin exists is triggered by the pam_nologin module You can skip the pam_nologin invocation for users matching certain criteria with pam_succeed_if
