# WARNING: If you intend to restrict a user to only running the
# sshuttle command as root, THIS CONFIGURATION IS INSECURE.
# When a user can run sshuttle as root (with or without a password),
# they can also run other commands as root because sshuttle itself
# can run a command specified by the user with the --ssh-cmd option.
# INSTRUCTIONS: Add this text to your sudo configuration to run
# sshuttle without needing to enter a sudo password. To use this
# configuration, run 'visudo /etc/sudoers.d/sshuttle_auto' as root and
# paste this text into the editor that it opens. If you want to give
# multiple users these privileges, you may wish to use use different
# filenames for each one (i.e., /etc/sudoers.d/sshuttle_auto_john).
# This configuration was initially generated by the
# 'sshuttle --sudoers-no-modify' command.
