Even though many of us are using enterprise-ready kernels in datacenters, there is almost nobody who hasn't at least considered building a kernel for his laptop / PC.
+
=== Description ===
We are showing here how an intermediate Linux user can use an alternative to the standard beginners "genkernel" approach,  to compile a custom kernel, in a relatively speedy and easy set up.
+
irssi is a small command line IRC client based on ncurses. It's a great thing to use when you SSH into a server, or just simply for your main IRC client.  
  
== Minimum Requirements ==
+
=== Installation ===
* '''Understand the command line'''
+
The install of irssi is pretty straight forward. There are not many USE flags, but one that is worth looking at is the {{c|SSL}} flag. This enables you to use SSL when connecting to servers.
* '''Know where the kernel files are located'''
+
{{console|body=
 +
###i## echo "net-irc/irssi ssl" >> /etc/portage/package.use
 +
###i## emerge irssi
 +
}}
 +
=== Using irssi ===
 +
Using irssi initially can be a little intimidating if you're not used to command line programs. To first start irssi, you just simply run:
 +
{{console|body=
 +
$ ##i##irssi
 +
}}
 +
There are flags you can pass to the command line while starting irssi, such as:
 +
{{console|body=
 +
$ ##i##irssi -n mynick -c irc.freenode.org
 +
}}
 +
This would connect you to Freenode with the nick 'mynick'. Or alternatively you can just run the {{c|irssi}} command and connect via SSL if you need to:
 +
{{file|body=
 +
/connect -ssl irc.freenode.org
 +
}}
 +
This will automatically connect you over port 6697.
  
== Assumptions ==
+
When you have connected to the server of your choice, you can join a channel simply by:
You start from an installed Funtoo system on the disk, or at least, you are on stage3 in a chrooted environment from a live cd, following somehow the Funto [[Installation (Tutorial)|Installation Tutorial]].
+
{{file|body=
 +
/j #funtoo
 +
}}
 +
If you want to leave any channel you've entered you can use the {{c|part}} command:
 +
{{file|body=
 +
/part #funtoo reasons...
 +
}}
 +
There are a few ways of navigating through your channels, you can use {{c|alt+<nowiki>{1-9}{q-p}</nowiki>}}, or alternatively you can use the {{c|window}} command that is in irssi:
 +
{{file|body=
 +
/window 1
 +
/window 2
 +
/window 3
 +
}}
 +
For as many channels you are apart of.  
  
== Less advanced version ==
+
When you're ready to leave, you can simply type in:
=== Emerging the kernel sources ===
+
{{file|body=
To begin, we have to figure out which kernel sources we will use. If you are unsure about which sources are available and what their benefits and drawbacks are, check out the [[Funtoo_Linux_Kernels| Kernels]] page.
+
/exit
 +
}}
 +
Which will close out connections to the IRC networks you've joined, and take you back to your console window.
 +
=== Themes and scripts ===
 +
==== Scripts ====
 +
There are a few things you can do to make irssi look a little bit better and add some cool features. There are a few plugins that are pretty useful, such as {{c|fnotify.pl}} which is a script that utilizes {{f|libnotify}} to send you popup notifications for when your nick is pinged or you are sent a private message.  
  
After you have made a decsion as to which kernel you want to install, emerge it:
+
{{file|name=fnotify.pl|lang=perl|desc=fnotify.pl|body=
<console>
+
# todo: grap topic changes
###i## emerge vanilla-sources
+
</console>
+
Portage will now go about installing the sources to ''/usr/src''. It will also symlink the kernel-version directory to a directory called ''linux''.
+
  
=== Configuring the kernel ===
+
use strict;
Now that the kernel sources are on your system, you should configure them. To do this, change your directory to ''/usr/src/linux''
+
use vars qw($VERSION %IRSSI);
<console>
+
###i## cd /usr/src/linux
+
</console>
+
As we are now in the kernel sources directory, we can run a script that allows us to modify them. Run:
+
<console>
+
###i## make menuconfig
+
</console>
+
While you edit the sources, keep the following in mind:
+
* To build something into your kernel, press y when you have it selected.
+
* To exclude something from your kernel, press n when you have it selected.
+
* To build something as a module, press m.
+
  
Things that you may need to include in your kernel:
+
use Irssi;
* Wireless/LAN drivers
+
$VERSION = '0.0.3';
* Support for your graphics card
+
%IRSSI = (
* Support for your audio card
+
authors    => 'Thorsten Leemhuis',
* Support for USB devices
+
contact    => 'fedora@leemhuis.info',
{{fancynote| Many pages on the wiki will tell you the kernel requirements for the application that they are about. Keep your eyes open for the blue background, white text sections of pages. Like on this one: [[uvesafb| uvesafb]]}}

 +
);
  
=== Building and installing the kernel sources ===
+
#--------------------------------------------------------------------
After you finish configuring your kernel sources, you will need to build them. To build your sources, run the following:
+
# In parts based on knotify.pl 0.1.1 by Hugo Haas
<console>
+
# http://larve.net/people/hugo/2005/01/knotify.pl
###i## make
+
# which is based on osd.pl 0.3.3 by Jeroen Coekaerts, Koenraad Heijlen
</console>
+
# http://www.irssi.org/scripts/scripts/osd.pl
{{fancytip| You can add -j<number of processing cores + 1> after make to build the kernel more quickly.}}
+
#
 +
# Other parts based on notify.pl from Luke Macken
 +
# http://fedora.feedjack.org/user/918/
 +
#
 +
#--------------------------------------------------------------------
  
When the kernel and its modules finish building, install them:
+
#--------------------------------------------------------------------
<console>
+
# Private message parsing
###i## make install modules_install
+
#--------------------------------------------------------------------
</console>
+
Now that you have installed your kernel and modules, it is a good idea to install an initramfs. If your system has a separate ''/usr'' partition, is encrypted, or uses some other non-standard configuration, it will probably not boot without an initramfs. See [[Building_a_Kernel_from_Source#Initramfs| Initramfs]].
+
  
== Advanced version ==
+
sub priv_msg {
=== Getting ready to start ===
+
my ($server,$msg,$nick,$address,$target) = @_;
 +
filewrite($nick." " .$msg );
 +
}
  
{{fancynote| In this case we are building a kernel that is booting root in LVM over encrypted LUKS container.
+
#--------------------------------------------------------------------
If you don't have this setup, don't worry, you just don't need all the modules, but everything else is similar.}}
+
# Printing hilight's
First, there is the decision which linux kernel sources we need.
+
#--------------------------------------------------------------------
There are plenty of them in the repositories around, often it is not easy to distinguish between them.
+
  
I would always trust my distribution of choice and take what is has to offer - and funtoo has a lot to offer!
+
sub hilight {
 +
    my ($dest, $text, $stripped) = @_;
 +
    if ($dest->{level} & MSGLEVEL_HILIGHT) {
 +
filewrite($dest->{target}. " " .$stripped );
 +
    }
 +
}
  
I really do recommend (especially if it is your first time) to build a debian-sourced genkernel like described in chapter 5 "Using Debian-Sources with Genkernel" in the [[Funtoo_Linux_Kernels| Funtoo Kernels Tutorial]].
+
#--------------------------------------------------------------------
 +
# The actual printing
 +
#--------------------------------------------------------------------
  
From there you should have a running system booting nicely from your own build (just little bit bloated) kernel. This is more than you can expect from any other ready to go distribution.
+
sub filewrite {
 
+
my ($text) = @_;
{{fancynote| We are using RedHat's dracut in order to build a nice initramfs (containing all the necessary tools and extra drivers our kernel might need to start the system). Although dracut is the way to go, more sophisticated and not as buggy as gentoo's genkernel approach, more and more funtoo geeks start using slashbeast's better-initramfs, which we will cover at the end of this howto! So after having set up a genkernel from debian or gentoo sources we are going to build a kernel with either (or both) dracut or/and better-initramfs. So gentoo sources with genkernel is always my backup if anything is not working correctly on my system. For the slightly more geeky approach with my own initram I am using pf-sources, ck-sources or any other more or less heavily patched sources.}}
+
# FIXME: there is probably a better way to get the irssi-dir...
 
+
        open(FILE,">>$ENV{HOME}/.irssi/fnotify");
Let's go!
+
print FILE $text . "\n";
 
+
        close (FILE);
=== Kernel Sources ===
+
}
The source you use on your system is up to you. For a laptop or desktop system, the following are recommended:
+
* '''{{Package|sys-kernel/pf-sources}}'''
+
* '''{{Package|sys-kernel/ck-sources}}'''
+
* '''{{Package|sys-kernel/gentoo-sources}}'''
+
* '''{{Package|sys-kernel/git-sources}}'''
+
* '''{{Package|sys-kernel/sysrescue-std-sources}}'''
+
* '''{{Package|sys-kernel/debian-sources}}'''
+
{{fancynote| If you are unsure of which sources you would like to use, emerge <code>gentoo-sources</code>. That's always a safe bet for a general system. For more information on available kernels, check out: [[Funtoo Linux Kernels]]}}
+
 
+
=== Prerequisites ===
+
 
+
Regardless of the tools you already have installed, it is recommended to follow the steps below, even if you find them to be redundant.
+
First, we edit our <code>/etc/portage/make.conf</code>:
+
 
+
<pre>
+
#These compiler flags are just tweaking (optimazation) and NOT necessary:
+
CFLAGS="-O2 -pipe -march=native -ftracer -fforce-addr"
+
CXXFLAGS="${CFLAGS} -fpermissive -fomit-frame-pointer"
+
KDIR=/usr/src/linux
+
KERNEL="symlink build"
+
USE="$KERNEL ....here are your use flags...."
+
## These modules are available:
+
## DRACUT_MODULES="dracut_modules_biosdevname dracut_modules_btrfs dracut_modules_caps dracut_modules_crypt dracut_modules_crypt-gpg dracut_modules_dmraid dracut_modules_dmsquash-live dracut_modules_gensplash dracut_modules_iscsi dracut_modules_livenet dracut_modules_lvm dracut_modules_mdraid dracut_modules_multipath dracut_modules_nbd dracut_modules_nfs dracut_modules_plymouth dracut_modules_ssh-client dracut_modules_syslog"
+
## We will use these modules for LVM / LUKS:
+
DRACUT_MODULES="crypt lvm plymouth biosdevname dmraid crypt-gpg dmsquash-live ssh-client syslog"
+
</pre>
+
 
+
Next, we set the package keywords by adding the following to <code>/etc/portage/package.use</code>:
+
 
+
<pre>
+
sys-kernel/dracut dm net device-mapper crypt lvm
+
</pre>
+
 
+
{{fancynote| If you don't have lvm over encrypted LUKS you just add the "net" keyword here, or "selinux".}}
+
 
+
 
+
Next, we build our packages:
+
<console>
+
###i## emerge -av app-portage/gentoolkit sys-kernel/pf-sources sys-kernel/dracut sys-boot/plymouth sys-boot/plymouth-openrc-plugin
+
</console>
+
 
+
=== Preparing the kernel ===
+
 
+
We go now to the sources directory and enter the following commands to update the kernel's  .config  file:
+
<console>
+
###i## cd /usr/src/linux/
+
###i## make clean
+
  CLEAN  .
+
  CLEAN  arch/x86/kernel/acpi/realmode
+

+
###i## zcat /proc/config.gz > /usr/src/linux/.config
+
</console>
+
 
+
Next, we run <tt>make localmodconfig</tt>. You will get some questions which you can answer mostly with either M (compiled as a module) or Y (compiled directly into the kernel). If you are not sure what to choose, press enter, and the default option will be selected.
+

+
###i## make install

</console>
+
  
== Initramfs ==
+
When you have the scripts you would like you would put them into {{f|~/.irssi/scripts}} and set a link to {{f|~/.irssi/scripts/autorun}}.
{{fancywarning| Make sure that you have built and installed your kernel sources / modules before building an initramfs.}}
+
{{console|body=
To get your initramfs up and running, check out the [http://www.funtoo.org/Initramfs Initramfs] page. After following all the directions on the page to get your initramfs set up, continue following the ones here.

 +
$ ##i##cd ~/.irssi/scripts/autorun
 +
$ ##i##ln -s ~/.irssi/scripts/nickcolor.pl .
 +
$ ##i##ln -s ~/.irssi/scripts/fnotify.pl .
 +
}}
 +
You can do this for as many scripts as you've chosen to use. They will automatically load when you start irssi. You can also manually load scripts:
 +
{{file|body=
 +
/load ~/.irssi/scripts/fnotify.pl
 +
Irssi: Loaded script fnotify
 +
}}
 +
Whichever works best for you is what you should do.
 +
==== Themes ====
 +
You can choose from many themes on the [http://irssi.org/themes irssi themes] page if you don't like the default look of it. Once you've chosen the them you like, you can simply put it in your {{f|~/.irssi/}} directory and when you run just run:
 +
{{file|body=
 +
/set theme mycooltheme
 +
}}
 +
And there you have it, the theme you have chosen is now there.
 +
=== Conclusion ===
 +
irssi is a great IRC client, and really helpful if you spend a lot of time in a terminal emulator or on a server.  
  
Update the <tt>grub.cfg</tt> with boot update, then reboot and see how it works!

Description

irssi is a small command line IRC client based on ncurses. It's a great thing to use when you SSH into a server, or just simply for your main IRC client.

Installation

The install of irssi is pretty straight forward. There are not many USE flags, but one that is worth looking at is the SSL flag. This enables you to use SSL when connecting to servers.

# echo "net-irc/irssi ssl" >> /etc/portage/package.use
# emerge irssi

Using irssi

Using irssi initially can be a little intimidating if you're not used to command line programs. To first start irssi, you just simply run:

$ irssi

There are flags you can pass to the command line while starting irssi, such as:

$ irssi -n mynick -c irc.freenode.org

This would connect you to Freenode with the nick 'mynick'. Or alternatively you can just run the irssi command and connect via SSL if you need to:

/connect -ssl irc.freenode.org

This will automatically connect you over port 6697.

When you have connected to the server of your choice, you can join a channel simply by:

/j #funtoo

If you want to leave any channel you've entered you can use the part command:

/part #funtoo reasons...

There are a few ways of navigating through your channels, you can use alt+{1-9}{q-p}, or alternatively you can use the window command that is in irssi:

/window 1
/window 2
/window 3

For as many channels you are apart of.

When you're ready to leave, you can simply type in:

/exit

Which will close out connections to the IRC networks you've joined, and take you back to your console window.

Themes and scripts

Scripts

There are a few things you can do to make irssi look a little bit better and add some cool features. There are a few plugins that are pretty useful, such as fnotify.pl which is a script that utilizes libnotify to send you popup notifications for when your nick is pinged or you are sent a private message.

fnotify.pl (perl source code) - fnotify.pl
# todo: grap topic changes

use vars qw($VERSION %IRSSI);
 
use Irssi;
$VERSION = '0.0.3';

sub priv_msg {
	my ($server,$msg,$nick,$address,$target) = @_;
	filewrite($nick." " .$msg );
}
 
#--------------------------------------------------------------------
# Printing hilight's
#--------------------------------------------------------------------
 
sub hilight {
    my ($dest, $text, $stripped) = @_;
    if ($dest->{level} & MSGLEVEL_HILIGHT) {
	filewrite($dest->{target}. " " .$stripped );
    }
}
 
#--------------------------------------------------------------------
# The actual printing
#--------------------------------------------------------------------
 
sub filewrite {
	my ($text) = @_;
	# FIXME: there is probably a better way to get the irssi-dir...
        open(FILE,">>$ENV{HOME}/.irssi/fnotify");
	print FILE $text . "\n";
        close (FILE);
}
 
Irssi::signal_add_last("message private", "priv_msg");
Irssi::signal_add_last("print text", "hilight");
 
#- end

Another very useful script is for colored nicks, to better tell people apart. Which can be found at irssi scripts called nickcolor.pl.

When you have the scripts you would like you would put them into ~/.irssi/scripts and set a link to ~/.irssi/scripts/autorun.

$ wget -O ~/.irssi/scripts/nickcolor.pl http://scripts.irssi.org/scripts/nickcolor.pl
$ cd ~/.irssi/scripts/autorun
$ ln -s ~/.irssi/scripts/nickcolor.pl .
$ ln -s ~/.irssi/scripts/fnotify.pl .

You can do this for as many scripts as you've chosen to use. They will automatically load when you start irssi. You can also manually load scripts:

/load ~/.irssi/scripts/fnotify.pl
Irssi: Loaded script fnotify

Whichever works best for you is what you should do.

Themes

You can choose from many themes on the irssi themes page if you don't like the default look of it. Once you've chosen the them you like, you can simply put it in your ~/.irssi/ directory and when you run just run:

/set theme mycooltheme

And there you have it, the theme you have chosen is now there.

Conclusion

irssi is a great IRC client, and really helpful if you spend a lot of time in a terminal emulator or on a server.
