Ubuntu 10.04 Login Screen and other things.

You want to change the login screen background?
Here is how:
It's best to chage your image to the resolution of your monitor - use gimp?
It may be easier to put the background image you wish in /usr/share/backgrounds first if not already there, doesn't really matter

-log out
-at the log in screen press CTRL+Alt+F1,
-enter user name and password
-Code:
export DISPLAY=:0.0
-press enter
Code:
-sudo -u gdm gnome-control-center
-press enter, expect errors,
-when terminal output stops press CTRL+Alt+F8

The Gnome Control Center should appear (it looks exactly the same as Appearance preferences from the Gnome Desktop, but , it relates to the login screen in this case.)
In Appearance
-choose Add and pick a new background, (or browse to one if it's in a different folder)
-close Gnome Control Center,
-press CTRL+Alt+F1
-at the terminal cursor type code:
sudo reboot

Terminal Command Line Web Browsing

We have all been introduced to a graphical web browsing about couple of decades, from way back use of Netscape and then comes IE developed by Microsoft and now with Firefox as well with other browsing tools available for both mobile and desktop computing.

How bout going back to an oldschool BBS or maybe using the CLI(command line interface) for discreet browsing. CLI browsing doesn't load images for graphical view and more of a keyboard typing is required.

Have anyone gone to BBS(bulletin Board System)? It is a command line interface using telnet or HyperTerminal which can connect to forums, emails, relay chatting, file transfer etc.



For some noob linux users, have you tried browsing the web using your Terminal command line interface?

There is some enhanced command lines that can be use in order to browse the web with CLI or Terminal. I use this mostly in some forum sites and emails.

Here's how.

#For Ubuntu you can use the 'w3m' command

#open your Terminal

$ w3m www.google.com

# Or you may explore the command extension for your preference with the help menu

$ w3m --help
or
$ w3m

There are also other which has same function and feature. You may also try 'links', 'links2' & 'lynx'
depending on which flavor you'd prefer. For me, I use links and links2 command. Also, some mouse clicks works with it, but still requires more of a typing skills.

You may also install it all so you can shift either which to use.

$ sudo apt-get install lynx

ex.
$ lynx www.xcon-technix.blogspot.com

$ sudo apt-get install links

ex.
$ links www.xcon-technix.blogspot.com

$ sudo apt-get install links2

ex.
$ links2 www.xcon-technix.blogspot.com

How to connect to a wireless network from the Ubuntu command line

Why use a friendly GUI when there’s cryptic shell commands out there?

Here’s how I connect:


$ sudo iwlist eth1 scan # eth1 is my wireless card.
eth1 Scan completed :
Cell 01 - Address: 0A:1D:19:15:C2:C1
ESSID:"airborneaccess"

48 Mb/s; 54 Mb/s
Extra:tsf=0000003befa89182



That scan lists every available access point. The important piece of information to extract here is the ESSID. Now I set my wireless card up to connect to that ESSID:


$ sudo iwconfig eth1 essid "ESSID of your acceesspoint"


And finally, I tell my card to request an IP address from the router:


$ sudo dhclient eth1 # gimme an IP address plz!
There is already a pid file /var/run/dhclient.pid with pid 6911

I can type these three commands way faster than waiting for the GUI to fire up. Here they are again, without all the output:


$ sudo iwlist eth1 scan
$ sudo iwconfig eth1 essid "ESSID of your acceesspoint"
$ sudo dhclient eth1


Sometimes, I need to connect to a network with a hidden ESSID. That’s just as easy. I just configure the ethernet card to connect to anything:


$ sudo iwconfig eth1 essid any # any is a keyword, not the name of an ESSID.


Finally, some networks require an access key. Sometimes, people can give you the human-friendly version, and you can type that in like this:


$ sudo iwconfig eth1 key s:password # translates to the hex for me.


Note the s: in front. That translates what I type into the hex jibberish.

Other times, people insist on giving you the goofy string of hex digits, so you can set it like this:


$ sudo iwconfig eth1 key ACDB-1234-1234-EFG2

Lucid Lynx 10.04 LTS

Upgraded to new LTS version of Linux Ubuntu 10.04 64bit




But still my lapbox is in dual boot with Windows 7 and using GRUB as my boot loader to select either OS. I use linux most of the time, whenever some work related compatibility doesn't seem to run in linux, thats the time I use to run windows 7.

My Untangle Box

I have recently put up a dedicated server box for my Firewall Enhancement in replace to OpenDNS. This serves my IPS/IDS, Spam Blocker, Ad Blocker, Phish Blocker, and most importantly the Web Filter. Below are the change log feature of version 7.2 from 7.1 you can check out full version features at www.untangle.com



Untangle 7.2 Release Features

We are pleased to announce general availability of Untangle 7.2. Our latest version includes a new free application for internet access control, as well as a host of enhanced features and improvements.
Captive Portal

Terms-of-Use Acceptance: Most businesses, schools and government departments have an Internet policy in force. However, raising awareness of it, and ensuring adherence to it, remains a problem. Untangle Captive Portal enables organizations to display a mandatory default web page to all users, before they are able to access the internet. This Captive Portal web page can display and enforce an acceptable use policy, as well as authenticate users, to control internet access.

Organization may wish to require users that want access to the internet to first agree to the organization’s terms of use. Only on acceptance are they given access to the internet.

Authentication Mechanisms: Captive Portal supports a wide array of authentication mechanisms, from basic local directory-based authentication (on the Untangle server) to authentication through an Active Director server or RADIUS server when coupled with Untangle's Directory Connector.

Maximum Flexibility: Captive Portal is highly customizable. It allows organizations to establish User Defined Capture Rules, to handle a variety of exceptions that may be required. For example, authentication may only be required during a specific time period; certain computers and users may be exempt from authentication by adding them to Pass Lists

Customizable: Captive Portal has a completely customizable log-in page, which allows for organizations to add their own messages to the log-in screen. Web developers can write fully custom login pages allowing for more complex setups, like charging users for internet access.

Access Logs: All attempts to log in to the internet through the Captive Portal are automatically logged. This provides a clear acceptance-of-terms audit trail for organizations and with it the teeth to enforce policy.
Directory Connector

Untangle's AD Connector has been renamed Directory Connector. This is because it now supports both Microsoft Active Directory server, and RADIUS server. This provides a wider range of user directories against which Untangle administrators can authenticate users.

Directory Connector now supports the notion of groups in Microsoft Active Directory server. This significantly reduces the administrative burden for Untangle administrators, as polices can be set for existing AD groups and will automatically apply to all users and subgroups within that group.
Reports

Many enhancements have been made to Reports, including:

* Daily, weekly and monthly reports
* New Highlights: a Summary of all reports
* New "Server" reports show memory, disk, CPU, swap

Other enhancements

ZTE MF637 internal parts "SmartBro Plug-It USB"

I was eager to put an external antenna to my USB modem ZTE MF637, an HSDPA/HSUPA 3.75G from SmartBro Plug-It. I found two internal antenna, one might be the GPRS/EDGE and the other one is for 3G. Though I can't determine well which antenna is 3G and the other. Both has different frequency of operation, whereas 3g UMTS is 2100Mhz and so on.

There is only one internal antenna connector, and which I think is for GPRS/EDGE only.

Ethernet over power lines: Netgear makes major improvements

(from TechRepublic)
Using in-house electrical wiring for networking computers usually only happens if wires can’t be run or Wi-Fi connections are less than adequate. Netgear’s new Ethernet over power-line devices may change that.

————————————————————————————————–

Last year, I went through what I consider the perfect storm of network cabling. To explain, I was asked by a client to set up an Ethernet network at one of his rental facilities. For some reason, I could not run cables. To make matters worse, there was an inordinate amount of grounded metal (galvanized studs) acting like RF sponges. That eliminated Wi-Fi gear as an option.

Out of options, I tried Netgear’s Powerline equipment and was disappointed. Bandwidth never came close to what Netgear advertised. Still, the client was not deterred by the limited throughput. They were happy to have anything at all. I guess sneaker networks get old fast.

New and improved

Previously, Netgear offered two product lines, one rated at 85 Mb per second and one at 200 Mb per second. Both were lucky to achieve half that throughput. Still, Netgear seems determined to make Power line Ethernet a viable solution. They just announced a new product line that may take care of the bandwidth problem. The new adapters have the following enhancements :

Throughput speed of 500 Mb per second.
The first devices to comply with IEEE draft P1901 standard.
Prioritized Quality of Service (QoS), important for streaming media applications.
Simple 128-Bit AES encryption, using the “Push-and-secure” button.
Backward compatible with other Netgear Powerline products and equipment from other vendors, if it’s HomePlug AV certified.

Two models

Netgear is offering two models, the Powerline AV 500 Adapter Kit/XAVB5001 (courtesy of Netgear):





As well as the Powerline AV+ 500 Adapter Kit/XAVB5501 (courtesy of Netgear):



Netgear mentions that the devices are designed to leave the second socket of an outlet pair open for use. Also, the XAVB5501 provides a filtered power socket, if outlets are in short supply. Each kit comes with two adapters.

Install 64-bit Adobe Flash Player on Ubuntu (updated to 9.10)

FlashNow that there is a java browser plugin and a working wine for 64-bit on the Ubuntu repositories, there is not much holding back 64-bit Linux on the desktop. Maybe the only thing missing is the Adobe Flash player. Most of the time Flash is just annoying, nevertheless sometimes needed. Luckily, there is now a Flash Player release for 64-bit Linux (however, still beta alpha but stable so far) . I am pretty sure the instructions are identical for other Linux distributions.

To install it:

1. Download it from here (now here).

2. Unpackage it using a terminal (with the assumption your firefox downloads into your Desktop as default):
cd Desktop
tar xvzf libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz

(The name of the tar.gz file may change when a new version is released, change accordingly).

3. Create a plugin directory in your $HOME (instead of a system directory):

cd
mkdir -p .mozilla/plugins

4. Move the file to the plugin directory:
mv Desktop/libflashplayer.so .mozilla/plugins

5. Restart firefox. Go to about:plugins to see if it’s enabled:
about:plugins

That’s it.

Edit: Alternatively, you can use the graphical approach:

1. go to the download pages and click on “Download 64-bit Plugin for Linux (TAR.GZ, 3.64 MB)”.
2. select “Open with ” in firefox (you have to click on open to enable the ok button) and clck on OK.
3. The archive manager will open and show you the libflashplayer.so file.
4. Click on extra and a save window will open.
5. Type ctrl + h to show hidden files. Go to .mozilla (dubble click).
6. If no “plugins” directory is present, click on “Create Folder” on the top right and type as name “plugins” (without the quotes). Press Ener.
7. Click on Extract.
8. Click on Close on the windows showing the result.
9. Close the archive manager.
10. Restart firefox.
