Ubuntu Server 10.04 CLI Headless server | Allowing user to SUDO and Hosting Mediawiki


Hello all,

I am using Ubuntu Server 10.04 LTS.

I fiddle with my headless Linux server here and there in my spare time as time allows. A while back I accidentally removed my user login from being able to perform sudo commands. I have to type the "su" command before performing any root functions.

I find this annoying, I used to be able to, but after changing my login to different groups I somehow removed that privilege.

My login is a member of the group named "ftp" currently, and I think when I moved myself into that group, it pulled me out of the root group.

How would I put myself back into the root group, while still retaining the current group I am in?

---------------

2nd question is in regards to hosting a MediaWiki blog.

I have followed all the instructions here:
http://www.mediawiki.org/wiki/Manual...n_Ubuntu_10.04

I am extremely new to using Ubuntu, but have a very fundamental understanding of the internet.

This pc is behind a router doing port forwarding on port 80 (among many other ports), and the router has a static IP address configured to it.

After following all the instructions, I am lost on how to actually get to the website.
Now I do not have an A record set up or a domain registered, but in theory, I should just be able to open a web browser, punch in the wan ip address of the router and have it port forward to the server. I have also tried form inside the network to try to access it via its private ip address . THis is what I am entereing into my url bar:

192.168.1.102/mediawiki/index.php
192.168.1.102/mediawiki/index.php/main
I have tried just the ip in the url bar , nothing seems to work, and the same goes when I try to access it via the wan. What am I doing wrong?


The following is the output from my LocalSettings.php file:

# This file was automatically generated by the MediaWiki installer.

You need to be a member of the admin group to sudo on Ubuntu.
See this for fixing a broken sudo from Ubuntu's recovery mode: http://psychocats.net/ubuntu/fixsudo

first question: try adding your login name to /etc/group 'adm' line 5 or so:

adm:x:4:your_login_name


regarding your second question : Did you see the big warning on the top of the wiki installation instruction page ?

Quote:
Warning: This page describes the installation of an obsolete version of MediaWiki which does not receive security patches. Distribution packages are usually outdated, also they like to move around files, change the files, and do other batshit insane things. As such.....
Were you able to go to http://localhost/mediawiki page to setup the wiki ?

Can you still get into that page ?
