sudo doesn't work, reporting error in sudoers file, wierd behaviour

Trying to do something with sudo, it returns:

>>> /etc/sudoers: syntax error near line 5 <<<
sudo: parse error in /etc/sudoers near line 5
sudo: no valid sudoers sources found, quitting

My /etc/sudoers:

Defaults   env_reset

root   ALL=(ALL) ALL
alex   ALL=(ALL) ALL

Defaults:alex timestamp_timeout=0

Where is my error?

What's that "alex" doing in the defaults line?

It's there for disabling 15 minutes "sudo" acception without alex password.

I misread, that's indeed correct syntax. Sorry, can't help you further I'm afraid.

Try to comment every single line and check out. Have you edited the file in the last time?

Tried to comment one, then another... Until I commented all of them. Still error near line 5...

> Have you edited the file in the last time?

Yes, just today, after installing Arch (I was reinstalling it).

Just noticed that I have "/etc/sudoers.d" directory which contains nothing. Maybe I should do something with it?

Re: sudo doesn't work, reporting error in sudoers file, wierd behaviour

Mine is empty, too. do you have a sudoers.pacnew? try this one.

EDIT:

I dunno whether it makes a difference or not,...did you use visudo? Maybe it troubles editing 'manually' via "<editor> /etc/sudoers".

No, I don't. Can you post your sudoers file for me to try?

Re: sudo doesn't work, reporting error in sudoers file, wierd behaviour

this is my current sudoers.pacnew....looks a bit weird. the early versions have been more clear...

## 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

##
## 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 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!/sbin/reboot !log_output

##

my current sudoers file:

# 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

# User alias specification

# Cmnd alias specification

# Defaults specification

# Runas alias specification

# User privilege specification
root    ALL=(ALL) ALL

# Uncomment to allow people in group wheel to run all commands
# %wheel        ALL=(ALL) ALL

# Same thing without a password
# %wheel        ALL=(ALL) NOPASSWD: ALL

# Samples
# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users  localhost=/sbin/shutdown -h now

I tried this and it returns error near line 68 this time.
What version of sudo do you have in your system? Mine is 1.7.4.p4-1.

Try hitting enter on the last line of the file

Re: sudo doesn't work, reporting error in sudoers file, wierd behaviour

That helped! Thanks! I pretty sure I didn't have this "sudo" peculiarity before...
Do all the Arch config files need this "enter in the end of file"?

Re: sudo doesn't work, reporting error in sudoers file, wierd behaviour

No, but I guess thats why you should use visudo to edit sudoers

## 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.
