Can'tedit anything-Sudoers file? [SOLVED]

[travalon]

I have attempted a couple of things on my new install of Salix. Nothing has worked. I am a noob to linux in general and a super noob to Salix. The thing I am trying to do at the moment is edit my conky config file. I can open it and edit it but I can't save it. Also when I try to do things in the terminal I get a "not in the sudoers file" followed by a threat to report me to me, as I am the sole user of this machine. I would like to add myself to the sudoers file but I don't know where it is or how. I believe if I get into the sudoers club things will be fine for a while.

you might try gksu or kdesu.

Code: Select all

gksu leafpad

Code: Select all

kdesu kwrite

Without stating exactly what you attempted to do, nobody can help you.

Too many problems with this one. First, you have a lack of understanding file ownerships and permissions. It's obvious that you don't have permissions to edit that file you're talking about. Here's a quick introduction: http://www.tuxfiles.org/linuxhelp/filepermissions.html

Since you say it's a conkyrc file, I doubt it's a system file. It's most probably a file that you used in a previous /home directory, created with another distribution, using different user credentials (most importantly UID).

Now, about the "sudoers" thing. The answer to how do you get into the sudoers club, is "run visudo as root, so you can edit the sudoers file". But I don't think that's what you expected. Also, here's an FAQ on that: http://polishlinux.org/first-steps/root ... /sudo-faq/

Why are you trying to use sudo? And how do you think it would work? This is not ubuntu. sudo is not configured by default the same it is configured in ubuntu and thus it cannot be used by default the same way as it does in ubuntu. You can in fact configure it the same way, but you need to understand what you're doing and do it yourself. In slackware/salix, the su command (or gksu or kdesu for the graphic equivalents) is used to login as the root user and run commands as that user.

I'm a noob too when it comes to Slackware/Salix. I'll try to explain the way i did it.

1. To edit most files in Linux you have to be ROOT, except if the file belongs to you (if it is in the /home file) then you can do it as travalon (user). Clear as mud?

2. You are trying to edit your .conkyrc file which is a "dot file" and is in your /home directory, therefore, you can do this as 'user'.
Example:

Code: Select all

$ nano .conkyrc
edit the file and then save and exit.
Control + o  saves the file
Control + x  exits the editor nano
Done!

To belong to the sudo group, i did this:
The file /etc/sudoers is outside your /home, thus you have to become ROOT, launch a terminal:

Code: Select all

$ su
password: type here your root password
and you become ROOT when you see the hash mark (#)

Now you're ROOT and can edit the /etc/sudoers file:

Code: Select all

# nano /etc/sudoers
edit, adding the line you want to the file.
(i added myself to the group 'wheel' and uncommented the line for those belonging to that group)

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

Edit your .bashrc as user

Code: Select all

$ nano .bashrc
and add this line:
export PATH=/sbin:/usr/sbin:$PATH
save/exit

#reboot

when you come back try using sudo:

Code: Select all

macondo[~]$ sudo slapt-get -u

Now you're ROOT and can edit the /etc/sudoers file:

Code: Select all

# nano /etc/sudoers
edit, adding the line you want to the file.
save/exit

Don't ever ever do that. The sudoers file should only be edited using the visudo command.

Noted.
Explain this to me please? Is there a difference between vi/vim and nano? Or maybe there is another reason dealing with security? I'm curious.

[gapan]

Nothing to do with nano vs vim.

Code: Select all

man visudo

[macondo]

gapan: i went to the polishlinux link and got this:

Code: Select all

Instead, use the visudo command:

# visudo

This protects from conflicts (when two admins edit this file at the same time) and guarantees that the right syntax is used (the permission bits are correct).


[macondo]

I did man visudo, i gotcha!
OK, because nano is my export editor in my .bashrc, when i visudo as root, the editor is nano (i hate vim).
Thanks gapan, another thing learned today

Just remember press the "Ins" key to edit then "Esc" to

Code: Select all

:w

"write"

and

Code: Select all

:q

"quit"

and vi can be as easy as nano.
