Help!!! Seem to have busted /etc/sudoers :( bugger...

Hi, second post!! First one went well, now I'm a bit concerned - I don't wanna turn the AAO off incase I've done something monumentally stupid.

Edited /etc/sudoers in root mousepad (yes, I know now - that's a daft thing to do, and should use visudo) to allow all users access to the wvdial command aaaaaaaaaaaaaaaaaaaand... something has gone horribly wrong!

The AAO now won't connect to the wireless network, which I'm presuming is because behind the scenes the network manager uses sudo to handle privelidge escalation for managing the network connection. The exact error I get is:

Code:

>>> sudoers file: syntax error, line 87 <<<<
sudo: parse error in /etc/sudoers near line 87

Now, I've tried and tried and tried to find out what the hell has gone wrong, I've even copied my /etc/sudoers file to usb flash so I can paste it up here (which I will do later in this post), but according to emacs, line 87 is the one that says

Code:

%wheel all=(all) nopasswd: all

which is one I never touched!!!

Ok, here is my sudoers file as it resides on my AAO:

Code:

## Sudoers allows particular users to run various commands as
## the root user, without needing the root password.
##

## Examples are provided at the bottom of the file for collections
## of related commands, which can then be delegated out to particular
## users or groups.
## 
## This file must be edited with the 'visudo' command.

## Host Aliases

## Groups of machines. You may prefer to use hostnames (perhaps using 
## wildcards for entire domains) or IP addresses instead.

# Host_Alias     FILESERVERS = fs1, fs2
# Host_Alias     MAILSERVERS = smtp, smtp2

## User Aliases

## These aren't often necessary, as you can use regular groups
## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname 
## rather than USERALIAS

# User_Alias ADMINS = jsmith, mikem

## Command Aliases
## These are groups of related commands...

## Networking
Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool

## Installation and management of software
Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum

## Services
Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig

## Updating the locate database
Cmnd_Alias LOCATE = /usr/sbin/updatedb

## Storage
Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount

## Delegating permissions
Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp 

## Processes
Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall

## Drivers
Cmnd_Alias DRIVERS = /sbin/modprobe

# Defaults specification

# Disable "ssh hostname sudo <cmd>", because it will show the password in clear. 
#         You have to run "ssh -t hostname sudo <cmd>".

#Defaults    requiretty
Defaults    env_reset
Defaults    env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR \
                        LS_COLORS MAIL PS1 PS2 QTDIR USERNAME \
                        LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION \
                        LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC \
                        LC_PAPER LC_TELEPHONE LC_TIME LC_ALL LANGUAGE LINGUAS \
                        _XKB_CHARSET XAUTHORITY GNOME_KEYRING_SOCKET GNOME_KEYRING_PID"

## Next comes the main part: which users can run what software on 
## which machines (the sudoers file can be shared between multiple
## systems).

## Syntax:

## 	user	MACHINE=COMMANDS
## The COMMANDS section may have other options added to it.

## Allow root to run any commands anywhere 

root	ALL=(ALL) 	ALL

## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.

# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands

%wheel	ALL=(ALL)	ALL

## Same thing without a password

%wheel	ALL=(ALL)	NOPASSWD: ALL

## Allows members of the users group to mount and unmount the 
## cdrom as root

# %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom

## Allows members of the users group to shutdown this system
# %users  localhost=/sbin/shutdown -h now

It fails on the line %wheel ALL=(ALL) NOPASSWD: ALL constantly...

what the hell is wrong can someone fix it - or ideally, post up an unedited sudoers file so I can restore it to my AAO rather than do a complete system restore???

Cheers...

 

OK, I have sorted it - broke out the restore dvd, untarred the HDC image, copied /etc/sudoers to my memory stick, stuck it in the AAO and we're back to firing on all 8 gigabytes!
