Ubuntu 7.10 Beta Download

Introduction to Ubuntu 7.10 Beta
The Ubuntu developers are hurrying to bring you the absolute latest and greatest software that the open source and free software communities have to offer. This is the Ubuntu 7.10 beta release, which brings a host of excellent new features.

Note: This is still a beta release. Do not install it on production machines. The final stable version will be released in October 2007.

Upgrading from Ubuntu 7.04
If you are upgrading from Ubuntu 7.04, see
Upgrade

New features since Ubuntu 7.04
GNOME 2.20
Gutsy Gibbon Beta brings you the latest and greatest GNOME 2.20 with lots of new features and improvements.

Desktop 3D effects
Compiz Fusion is enabled by default and will bring 3D desktop visual effects that improve the usability and visual appeal of the system. Ubuntu 7.10 automatically detects whether the hardware is capable of running compiz; if not, it falls back to normal desktop. Additional effects can be enabled in "System/Preferences/Appearance" under the "Visual Effects" tab. There you can also disable the effects entirely.

Desktop search
The deskbar applet is now included in the default configuration. It allows quick access to your common actions, including opening web bookmarks and searches, sending messages to your contacts, and more.


The Tracker indexer has been added to the desktop, making it easier and faster to search for your documents, photos, music, videos, chat logs, and all other files. You can use Tracker in the search dialog, the file selector, nautilus, or the deskbar applet.

Fast user switching
It is now possible to easily switch between user sessions without the inconvenience of entering your username or password numerous times, a time-saver on computers shared by multiple users.


Firefox plugins in Ubuntu
Firefox now comes with an improved plugin finder wizard that allows users to search and install packaged plugins easily, bringing users a richer web-browsing experience with the integrated security support of the rest of the Ubuntu system:


In addition, users can now open the Ubuntu application installer with a list of packaged Firefox extensions available by clicking on a link in the Firefox Addons dialog:


Dynamic screen configuration
Several drivers, including ones for ATI, nVidia, and Intel graphics chips now support the X Resize and Rotate Extension (xrandr). This enables dynamic monitor detection, and resizing and rotating of video output, for no-fuss support for projectors and external monitors.

If you have this hardware and used MergedFB / Xinerama previously, you may need to update your X configuration to use this new feature.

Graphical configuration tool for X
You can now configure what driver you want to use for your graphic card, change the default resolution for all users or change your monitor's refresh rate without having to turn to the terminal. A new GUI has been added making it easy to adjust your video and monitor settings. This tool can also set up dual screen capabilities for cards that use the Xinerama mode.



Fully automatic printer installation
Printers are now automatically configured by merely plugging them in and turning them on. Printer setup cannot get any easier!



Handling of non-free device drivers
Restricted-manager can now handle drivers which are free in themselves, but which require non-free firmware or other packages to operate. Only three clicks are needed to fetch and install firmware for wireless cards with Broadcom chipsets, and for a number of Winmodems commonly found in laptops, provided that you have an alternative Internet connection.

When restricted-manager detects hardware for which a restricted driver is available, a notification window pops up:



NTFS writing
While previous Ubuntu releases only supported read access to Windows (NTFS) partitions, Gutsy Gibbon now fully supports reading and writing to them, by integrating the NTFS-3g project. This significantly eases file and document sharing with Windows.

Power consumption
Ubuntu includes the latest Linux kernel, featuring dynticks. It allows the processor to use less power and produce less heat. For laptops this means more battery life and burn-free laps and for desktops and media center PCs, a quieter, cooler environment.

AppArmor security framework
This easy-to-deploy kernel technology limits the resources an application is allowed to access and can be used to provide an added layer of protection against undiscovered security vulnerabilities in applications. Head to the AppArmor user guide to learn about this new security feature.

Additional installation profiles for Ubuntu Server
New pre-configured installation options have been added to the Ubuntu Server CD. Mail Server, File Server, Print Server, and Database Server options join existing LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.

Profile-based Authentication Configuration
Deploying authentication configuration has become a lot easier with the addition of auth-client-config. Files may be added to the profiles database, allowing for an administrator to set up a single profile for site-wide network authentication roll-outs. Find out more about AuthClientConfig.

Improved thin-client support
The speed of LTSP thin clients has been greatly improved through the use of compressed images, and LDM, the thin-client login manager included in Edubuntu, also now has support for autologin, multiple servers, and unencrypted graphics transport as an additional speed boost.

Download
Get it while it's hot. ISOs and torrents are available at:

Easiest way to Install Real Player in ubuntu

1) Download the version of RealPlayer thats prepackaged for Xandros Linux. Its a .deb package that works under Hoary.

Donwload Package HERE

2) Uncompress the .tar.zp2 file to get realplay_10.0.2-1_i386.deb

3) Open a command line shell and cd into the directory that you saved the deb file, (default is ~/Desktop

4) Use Sudo to install the file: sudo dpkg -i realplay_10.0.2-1_i386.deb

Unfortunately as of this writing, Real Player conflicts with Enlightened Sound Daemon. You'll need to use gconf and set /desktop/gnome/sound/enable_esd to false (uncheck its box) to disable it. Reboot, and you should be all set.

Dual-Booting Windows XP/Vista And Ubuntu 7.04

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

In this tutorial I will teach you how to dual-boot between Windows XP/Vista and Ubuntu.

This tutorial will be split up into two parts:

one for people who have no operating system installed.
two for people who have Windows XP/Vista installed and don't want to re-install Windows.
lo
Fresh start

In this part I will go though every step from installing Windows and Ubuntu to creating the dual-boot.
Windows XP + Ubuntu 7.04

What you will need:

* Windows XP Boot Disk
* Ubuntu 7.04 Boot Disk

Make sure your computer is set to boot from a CD.

To check this go into your BIOS. From there go to "Boot" and go to "Boot Priorities". Make sure CD-ROM is set to boot first and you're all set.
Installing Windows XP

Now I am going go over how to install Windows XP step-by-step.

1. Make sure your XP boot up disk is in the CD-ROM and start your PC.

2. A blue MS-DOS screen will load up first asking you if you want to install drivers or run an Automated System Recovery. Just wait for them to go by and then Windows will begin to load files needed to install XP.




Windows XP requires at least 1.5 gigabytes of hard drive space.
1000 megabytes (MB)= 1 gigabyte (GB). So when entering XP's partition make sure to write it as 90000 instead of 90, because it reads in megabytes, not gigabytes.












Congrats! You have fully installed Windows XP on your system. Activate windows if you want or do anything thing else to it. When ready go on to the next part to install Ubuntu and get the dual-boot up.

Insert the Ubuntu 7.04 boot disk and start up your computer. The boot screen will come up next. Highlight the Start or install Ubuntu choice and press Enter. Be patient while the loader goes back and forth. This may take a few minutes


Ubuntu Installation


After that Ubuntu will load up and you will be presented with a very bare screen. Double click on the Install icon to begin setting up Ubuntu.



After you double-click on the install icon it will first ask you to pick your preferred language. Choose one and click Forward




The next screen will ask you to pick a location near you for time purposes.




Once again it is time to partition your hard drive. From this screen make sure that Manual is checked and click Forward.




Now you should see a screen entitled Prepare partitions. We are now going to create the partition in which Ubuntu will run on plus a file called "SWAP" to act as virtual memory.


First let's create the SWAP file. Click on New partition. The SWAP file won't need a whole lot of space to run, so just give it 512 megabytes which will be more than enough for it to run. Now just change the Use as: option to SWAP while keeping the type of partition as Primary and the location as Beginning. Click OK to add it.


Now make sure free space is highlighted and click New partition again. This time we will add the hard drive space for Ubuntu to use. Give it what ever amount of space you would like depending on your hard drive space. Just remember to give it at least 2 GB though I recommend you give it much more. Now change the Use as: to ext3 and keep the rest of the settings the same. Click OK to add




Next right-click on the partition ext3 and click edit. From here change the mount point to a forward slash / and click OK



You should see a screen similar to this one, but with the partition NTFS on it. Last thing to do before proceeding is check the box next to ext3 to format and then click Forward.



You should see a screen similar to this one, but with the partition NTFS on it. Last thing to do before proceeding is check the box next to ext3 to format and then click Forward.




The next screen is going to ask you if you want to import any accounts you may have on Windows XP. If you want to do it, if not just proceed.


Time to enter your personal information. Just as a note: your login has to be all lowercase letters.








Well congratulations you have just fully installed both Windows XP and Ubuntu 7.04 to run on the same system under a dual-boot! I hope you enjoyed reading this as I have had a blast writing it.

--------------------------------------------------------------------------------------
For Installation of UBUNTU after Installaling Vista Follow Above Procedure as It is....
For Dual Boot with Vista/Ubuntu you need:

* Windows Vista Boot Disk
* Ubuntu 7.04 Boot Disk

Make sure your computer is set to boot from a CD. or F12 on blue screen and set default boot CD option selected.

To check this go into your BIOS. From there go to "Boot" and go to "Boot Priorities". Make sure CD-ROM is set to boot first and you're all set.
Now I am going go over how to install Windows Vista step-by-step.

1. Make sure your Vista boot up disk is in the CD-ROM and start your PC.

2. When it begins to boot you should see a black screen with a loading bar. This may take a few minutes so just let it load everything.


Please go thr each individaul screen and install vista on your machie,, (If you really dont love your machine---hahaha)







The following screen will now ask you how you want to install. As you booted from the disk the top option is likely shaded out. So just click on Custom (advanced) to continue.






You have succesfully install Vista on your machine
now for installation of ubuntu on second part please follow the above installation procedure as on XP installation.

Avant Window Navigator Installation

Installing:

Repository:

NOTE: Repository is for Feisty 32-bit ONLY.

If you are using Feisty 32-bit, this is the recommended method of installation.

Just add this to your /etc/apt/sources.list:
Code:
deb http://download.tuxfamily.org/syzygy42 feisty avant-window-navigator
deb-src http://download.tuxfamily.org/syzygy42 feisty avant-window-navigator
Then do this in a terminal:
Code:
wget http://download.tuxfamily.org/syzygy42/8434D43A.gpg
sudo apt-key add 8434D43A.gpg
rm 8434D43A.gpg
sudo apt-get update
Available packages:
avant-window-navigator-svn - the latest development version of AWN.
affinity - the latest stable version of affinity.
affinity-svn - the latest development version of affinity.
All -svn packages are updated daily.

NOTE: The Affinity in the repo (both stable and svn) only supports tracker for its search backend. If you prefer to use beagle, you will need to follow the instructions below to compile Affinity from source.
NOTE: There is no stable AWN currently because the only stable release of AWN is actually worse than SVN. Use the SVN build for now, and when the next stable version is available, I will build a package for it.

If anyone wants to create and maintain packages for other Ubuntu versions, I will gladly host them as well, and I can provide scripts for building the svn versions (almost) automatically.

Compiling from source:
If you're not running Feisty, you'll have to compile it yourself.
NOTE: Keep the source directory, you'll need it if you ever want to uninstall.

Avant-Window-Navigator (stable):
No instructions for the stable version, as it requires a patched libwnck and is not as stable/functional as the svn version. Use svn for now, when the next stable release comes out I'll post instructions here.

Avant-Window-Navigator (svn):
First install the dependencies:
Code:
sudo apt-get install build-essential autotools-dev libxdamage-dev libxcomposite-dev libgnome2-common libgnome2-dev libgnome-desktop-dev libgnome-vfs-dev libgtk2.0-dev libwnck-dev libgconf2-dev libglib2.0-dev libdbus-glib-1-dev libgnomevfs2-0 libgnome-desktop-2 libgnome2-0 libwnck-common python-gtk2 python-gconf subversion gnome-common
Now, open a terminal in the directory you want to build AWN in (I use ~/Installs/avant/) and do this:
Code:
svn checkout http://avant-window-navigator.googlecode.com/svn/trunk/ avant-window-navigator
cd avant-window-navigator
./autogen.sh
make
sudo make install
Affinity (stable):
First install the dependencies:
Code:
sudo apt-get install build-essential autotools-dev libgnome-vfs-dev libgtk2.0-dev  libgnome2-dev libgnome-desktop-dev libgnomevfs2-0 libgtk2.0-0 libgnome2-0 libgnome-desktop-2 libtrackerclient-dev libbeagle-dev
Important: You will also need to install and configure Tracker or/and Beagle for Affinity to work properly.

Now, open a terminal in the directory you want to build Affinity in (I use ~/Installs/affinity/) and do this:
Code:
wget http://affinity-search.googlecode.com/files/affinity-0.1.tar.gz
tar -xzf affinity-0.1.tar.gz
cd affinity-0.1
./configure
make
sudo make install
Affinity (svn):
First install the dependencies:
Code:
sudo apt-get install build-essential autotools-dev libgnome-vfs-dev libgtk2.0-dev  libgnome2-dev libgnome-desktop-dev libgnomevfs2-0 libgtk2.0-0 libgnome2-0 libgnome-desktop-2 libpanel-applet2-dev libtrackerclient-dev libbeagle-dev subversion
Important: You will also need to install and configure Tracker or/and Beagle for Affinity to work properly.

Now, open a terminal in the directory you want to build Affinity in (I use ~/Installs/affinity/) and do this:
Code:
svn checkout http://affinity-search.googlecode.com/svn/trunk/ affinity-search
cd affinity-search
./autogen.sh
make
sudo make install

Uninstalling:
I don't know why you would ever want to remove these awesome pieces of software, but in case you do, here's how.

Repository:

Just use synaptic or apt-get to remove the packages you installed.

Here's an apt-get line to remove all:
Code:
sudo apt-get remove avant-window-navigator avant-window-navigator-svn affinity-tracker affinity-beagle affinity-svn
Source:

Just open a terminal in the source directory (it should have a file called Makefile in it) you installed from and do
Code:
sudo make uninstall

UBUNTU HELP

If you have experience with Linux but are new to Ubuntu

If you're already familiar with Linux and just wonder why Ubuntu/Kubuntu uses sudo instead of root, this page isn't for you. You're really looking for https://help.ubuntu.com/community/RootSudo. It has a full explanation of why Ubuntu uses sudo instead of root and what the advantages and disadvantages of that choice are.

If you are new to Linux and Ubuntu

This page is for people who are new to Linux and Ubuntu/Kubuntu and want to know what the deal is with file permissions.

What you may be used to

My guess is you're probably a typical ex-Windows user (as I was), used to running as Administrator and being able to edit pretty much any file you want—even system files, even the registry—at will, very little stopping you... maybe the occasional "read-only" file that you can just make read/write by checking a little box in the Properties dialogue.

You may also never have installed and configured an operating system before (especially if you bought a computer with Windows preinstalled for you).

The need to edit system files

Some in the Linux camp will say "you shouldn't have to edit such-and-such a file." That's simply not true. Most Linux users aren't just user—they have to install and configure stuff themselves (as Dell or HP won't do it for them), usually configuration files and system files that normal users don't have to touch (say, in order to adjust the possible screen resolutions or install new software). You do have to edit these files from time to time. It's in your best security interests to have to go out of your way to edit them, but you should still be able to occasionally edit, move, copy, and rename files that only an Administrator (or Root) can modify.

Frequently edited system files

In Linux, the only files a user can modify are the ones in her home directory. For example, if the user's name is Bronte, the files she can modify live in the /home/bronte/ folder. Anything outside the /home/bronte folder she will not be able to modify. Some of the top files new installers need to modify are:

/etc/fstab (making hard drives and partitions viewable as folders)
/boot/grub/menu.lst (controlling the boot menu that lets you choose which operating system to boot to)
/etc/apt/sources.list (the list of sources from which you can easily install software)
/etc/X11/xorg.conf (screen resolution options, among other things)

and all of these files need Root privileges to modify.

Why do people recommend the command-line?

If you're like a lot of new Linux users, you probably have not yet embraced the command-line. Some people may have told you to "just"
sudo rm -r /usr/share/icons/themename
as if "rm" really means anything to you yet. The fact of the matter is that people recommend command lines because they're easier instructions to give than "Click on that button that looks like a purple arrow. A new dialogue will pop up with three choices. Pick the left-most choice."

Making system-wide changes graphically

Most new Linux users just want to be able to click and drag and drop. So one of these commands should be your new best friends...

If you're using Ubuntu (Gnome), press Alt-F2 and type

gksudo nautilus

If you're using Kubuntu (KDE), press Alt-F2 and type

kdesu konqueror

If you're using Xubuntu (XFCE), press Alt-F2 and type

gksudo thunar

What does sudo do?

What do these commands do? They allow you to generally operate as a regular user but have a temporary window within your user account to operate as Root (just within the Nautilus or Konqueror window you've opened). Once you close the Root window, it's just as if you're a user again. You don't have to log out of user, log in as Root, make changes, log out of Root, and log back in as user again. You can be Root and user simultaneously.

Mac OS X users may be familiar with this security model (Mac uses sudo, believe it or not!). As a Mac user, you operate as a user. When you want to install something, a dialogue box comes up asking for your administrator (sudo/root) password. Once it's installed, you're a user again.

So how does this work? Let's say you want to edit the /etc/apt/sources.list file. If you want to do it command-line style, you'd

sudo nano /etc/apt/sources.list
and then use Nano to edit it. If you do it the graphical way we've been talking about, you'd run the gksudo nautilus or kdesu konqueror command and a file browser window will pop up (with Root/administrator privileges just in that window). You'd browse to /etc/apt and find the file called sources.list. You'd click to open it, edit it, close it, and close the browser window, and it would be done.

Final recommendations

If you find that (especially right after the initial Ubuntu/Kubuntu install) that you're making a lot of changes as Root, create a launcher with the command gksudo nautilus or kdesu konqueror. Then, when you click on that launcher, you can type in your password, make root changes, and then close the window and be a user again.

Install Samba Server on Ubuntu

If you want to share files between your Ubuntu and Windows computers, your best option is to use Samba file sharing.

To install, first open a terminal window and enter the following command:

sudo apt-get install samba smbfs

We've got samba installed, but now we'll need to configure it to make it accessible. Run the following command to open the configuration file, substituting your editor of choice:

sudo gedit /etc/samba/smb.conf

Find this section in the file:

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba-HOWTO-Collection/ServerType.html
# in the samba-doc package for details.
; security = user

Uncomment the security line, and add another line to make it look like this:

security = user
username map = /etc/samba/smbusers

This will set Samba to use the smbusers file for looking up the user list.

Create a Samba User

There are two steps to creating a user. First we'll run the smbpasswd utility to create a samba password for the user.

sudo smbpasswd -a

Next, we'll add that username to the smbusers file.

sudo gedit /etc/samba/smbusers

Add in the following line, substituting the username with the one you want to give access to. The format is = "". You can use a different samba user name to map to an ubuntu account, but that's not really necessary right now.

= ""

Now you can create samba shares and give access to the users that you listed here.

You can also execute multiple commands by separating each one with a ; for example cd newdir; mkdir thatdir ; ls -la will first change directories to the newdir directory, then create a directory called thatdir, then list all the files in long format. You can string together as many commands as you like but caution should be used not to inadvertently do anything harmful.

If you think some thing need to be added to this list let me know.

Ubuntu Networking

Configuring Network Using Graphical Configuration Tool in Ubuntu

If you are new to networking the graphical configuration tool is your best method for configuring new hardware in Ubuntu.We are going to use GUI tool “network-admin” to configure networking. Remember, you must be root to run network-admin.

There are two ways to start network-admin first thing is you can use your terminal to type “sudo network-admin” it will start up or you can go to System—>Administration —>Networking

Configure Network Interface Using Command-Line

You can configure a network interface from the command line using the networking utilities. You configure your network client hosts with the command line by using commands to change your current settings or by editing a number of system files.

Configuring DHCP address for your network card

If you want to configure DHCP address you need to edit the /etc/network/interfaces and you need to enter the following lines replace eth0 with your network interface card

sudo vi /etc/network/interfaces

# The primary network interface - use DHCP to find our address
auto eth0
iface eth0 inet dhcp

Configuring Static IP address for your network card

If you want to configure Static IP address you need to edit the /etc/network/interfaces and you need to enter the following lines replace eth0 with your network interface card

sudo vi /etc/network/interfaces

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.3.90
gateway 192.168.3.1
netmask 255.255.255.0
network 192.168.3.0
broadcast 192.168.3.255

After entering all the details you need to restart networking services using the following command

sudo /etc/init.d/networking restart

Setting up Second IP address or Virtual IP address in Ubuntu

If you are a server system administrator or normal user some time you need to assign a second ipaddress to your Ubuntu machine.For this you need to edit the /etc/network/interfaces file and you need to add the following syntax.Below one is the only example you need to chnage according to your ip address settings

sudo vi /etc/network/interfaces

auto eth0:1
iface eth0:1 inet static
address 192.168.1.60
netmask 255.255.255.0
network x.x.x.x
broadcast x.x.x.x
gateway x.x.x.x

You need to enter all the details like address,netmask,network,broadcast and gateways values after entering all the values save this file and you need to restart networking services in debian using the following command to take effect of our new ipaddress.

After entering all the details you need to restart networking services using the following command

sudo /etc/init.d/networking restart

Setting your ubuntu stytem hostname

Setting up your hostname upon a ubuntu installation is very straightforward. You can directly query, or set, the hostname with the hostname command.

As an user you can see your current hostname with

sudo /bin/hostname

Example

To set the hostname directly you can become root and run

sudo /bin/hostname newname

When your system boots it will automatically read the hostname from the file /etc/hostname

If you want to know more about how to setup host name check here

Setting up DNS

When it comes to DNS setup Ubuntu doesn’t differ from other distributions. You can add hostname and IP addresses to the file /etc/hosts for static lookups.

To cause your machine to consult with a particular server for name lookups you simply add their addresses to /etc/resolv.conf.

For example a machine which should perform lookups from the DNS server at IP address 192.168.3.2 would have a resolv.conf file looking like this

sudo vi /etc/resolv.conf

enter the following details

search test.com
nameserver 192.168.3.2

Network Troubleshooting Tips

Networking is sometimes considered to be complex, and hard to troubleshoot and manage. However, Linux provides you with Some tools to figure out exactly what’s going wrong on your network, and how to fix it.Here we are going see some tools and how to check the network connectivity.

Ping

Ping is a computer network tool used to test whether a particular host is reachable across an IP network. Ping works by sending ICMP “echo request” packets to the target host and listening for ICMP “echo response” replies (sometimes dubbed “Pong!” as an analog from the Ping Pong table tennis sport.) Using interval timing and response rate, ping estimates the round-trip time (generally in milliseconds although the unit is often omitted) and packet loss (if any) rate between hosts.

This is very basic and powerful tool to check Internet connection

Example

ping -c 4 google.com

-c option is used to pass how many packets you’re sending

If everything working file you should get reply looks like below

Pinging www.l.google.com [64.233.183.103] with 32 bytes of data:

Reply from 64.233.183.103: bytes=32 time=12ms TTL=244
Reply from 64.233.183.103: bytes=32 time=12ms TTL=244
Reply from 64.233.183.103: bytes=32 time=12ms TTL=244
Reply from 64.233.183.103: bytes=32 time=12ms TTL=244

Ping statistics for 64.233.183.103:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 12ms, Maximum = 12ms, Average = 12ms

Traceroute

traceroute is a computer network tool used to determine the route taken by packets across an IP network. An IPv6 variant, traceroute6, is also widely available.Very useful to trace IP packets.

Example

traceroute google.com

ifconfig

The Unix command ifconfig can function as a tool to configure a network interface for TCP/IP from the command line interface (CLI).This is another easy tool to see if your interface is actually loading correctly.

Example

ifconfig

eth0 Link encap:Ethernet HWaddr 00:0A:E6:C6:07:85
inet addr:132.18.0.16 Bcast:132.18.0.255 Mask:255.255.255.0
inet6 addr: fe80::20a:e6ff:fec6:785/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:18458 errors:0 dropped:0 overruns:0 frame:0
TX packets:8982 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:4015093 (3.8 MiB) TX bytes:1449812 (1.3 MiB)
Interrupt:10 Base address:0xd400

Route

This is very useful to check routing config

Example

route -n

Netstat

If you want to see Routing Tables,all open ports,all listen ports

netstat -nr

-n means return numeric output (ie, IP address instead of hostname)

-r means print the routing table

find all open ports

netstat -a

find listening ports

netstat -l
