Sudo, still asking for password.

07 Apr 2017

If you setup sudo to not ask for password but it still do checkout this post.

There is great chances that there is other lines in your sudoers file overriden the NOSPASSWD rule. To check out do this sudo -l. You should see something like

Matching Defaults entries for dhilst on localhost:
    !visiblepw, env_reset, env_keep="COLORS DISPLAY HOSTNAME HISTSIZE KDEDIR LS_COLORS", env_keep+="MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE", env_keep+="LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT
    LC_MESSAGES", env_keep+="LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE", env_keep+="LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY", secure_path=/sbin\:/bin\:/usr/sbin\:/usr/bin

User dhilst may run the following commands on localhost:
    (ALL) NOPASSWD: ALL

If there are more lines after the NOPASSWD one then you may be in a group that has its own rules in sudoers file. Check the file. You may want to ignore comments so do this sudo sed '/^#/d; /^ *$/d' /etc/sudoers for ignore comments and blank lines. If you are in a group that has its own rule you have two options:

Remove the rule for the group.
Remove your rule and setup NOPASSWD for the group.

After that sudo -l should show only NOPASSWD rule and you will not be asked for password anymore. :-)
