I don't use sudo much, but have seen this in response to the su command.
AFAIK, it's just a warning basically asking if you know what you're doing. Also, again AFAIK, it only happens one time (for each user?). Have you entered the requested password (which would make sudo "work")?
What happens the second time you try?
[Although, if what I think I know isn't correct...what difference does it make that there's what essentially amounts to a multi-line prompt before you enter a password? On my production server I have a login banner:
Code:
************************************************************
* ****** *
* The Name of My Company , LLC *
* AUTHORIZED ACCESS ONLY *
* Login to this server is limited to authorized users only *
* Proceed ONLY if you are an authorized user. *
* Attempts to circumvent user authentication or security *
* of any host, network, web server or account will be *
* logged and prosecuted to the fullest extent possible. *
* ****** *
************************************************************
user@server's password:
That certainly doesn't impede logging in in any way. ]
[dummy@manjaroieo userx]$ sudo cat /etc/sudoers
## sudoers file.
##
## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors
## that prevent sudo from running.
##
## See the sudoers man page for the details on how to write a sudoers file.
##
##
## Host alias specification
##
## Groups of machines. These may include host names (optionally with wildcards),
## IP addresses, network numbers or netgroups.
# Host_Alias WEBSERVERS = www1, www2, www3
##
## User alias specification
##
## Groups of users. These may consist of user names, uids, Unix groups,
## or netgroups.
# User_Alias ADMINS = millert, dowdy, mikef
##
## Cmnd alias specification
##
## Groups of commands. Often used to group related commands together.
# Cmnd_Alias PROCESSES = /usr/bin/nice, /bin/kill, /usr/bin/renice, \
# /usr/bin/pkill, /usr/bin/top
# Cmnd_Alias REBOOT = /sbin/halt, /sbin/reboot, /sbin/poweroff
##
## Defaults specification
##
## You may wish to keep some of the following environment variables
## when running commands via sudo.
##
## Locale settings
# Defaults env_keep += "LANG LANGUAGE LINGUAS LC_* _XKB_CHARSET"
##
## Run X applications through sudo; HOME is used to find the
## .Xauthority file. Note that other programs use HOME to find
## configuration files and this may lead to privilege escalation!
# Defaults env_keep += "HOME"
##
## X11 resource path settings
# Defaults env_keep += "XAPPLRESDIR XFILESEARCHPATH XUSERFILESEARCHPATH"
##
## Desktop path settings
# Defaults env_keep += "QTDIR KDEDIR"
##
## Allow sudo-run commands to inherit the callers' ConsoleKit session
# Defaults env_keep += "XDG_SESSION_COOKIE"
##
## Uncomment to enable special input methods. Care should be taken as
## this may allow users to subvert the command being run via sudo.
# Defaults env_keep += "XMODIFIERS GTK_IM_MODULE QT_IM_MODULE QT_IM_SWITCHER"
##
## Uncomment to use a hard-coded PATH instead of the user's to find commands
# Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
##
## Uncomment to send mail if the user does not enter the correct password.
# Defaults mail_badpass
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot. Use sudoreplay to play back logged sessions.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output
##
## Runas alias specification
##
##
## User privilege specification
##
root ALL=(ALL) ALL
## Uncomment to allow members of group wheel to execute any command
%wheel ALL=(ALL) ALL
## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL
%mysudo ALL=(ALL) NOPASSWD: ALL
## Uncomment to allow members of group sudo to execute any command
# %sudo ALL=(ALL) ALL
## Uncomment to allow any user to run sudo if they know the password
## of the user they are running the command as (root by default).
# Defaults targetpw # Ask for the password of the target user
# ALL ALL=(ALL) ALL # WARNING: only use this together with 'Defaults targetpw'
## Read drop-in files from /etc/sudoers.d
## (the '#' here does not indicate a comment)
#####includedir /etc/sudoers.d
I'd say make sure you user is valid, and sudo group is valid, and remove or comment out the pamuser line under root. then try it again.
changing passwd
Code:
[dummy@manjaroieo userx]$ whoami
dummy
[dummy@manjaroieo userx]$ sudo passwd root
New password:
Retype new password:
passwd: password updated successfully
[dummy@manjaroieo userx]$
