Disable ipv6 on Debian HOW TO

I’ve recently installed a new LDAP server on Debian Lenny and I wanted to disable IPv6 as it is unnecessary for me in this moment. With netstat I checked the listening processes:

netstat -tunlp

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:389 0.0.0.0:* LISTEN 2226/slapd
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 2215/sshd
tcp6 0 0 :::389 :::* LISTEN 2226/slapd
tcp6 0 0 :::22 :::* LISTEN 2215/sshd
and lsmod showed something like this:
Module Size Used by
ipv6 235364 12
...
So, to disable IPv6 I changed /etc/modprobe.d/aliases:
...
# alias net-pf-10 ipv6
# Disable ipv6
alias net-pf-10 off
alias ipv6 off
...

put AddressFamily inet into /etc/ssh/ssh_config - restart ssh
in /etc/modprobe.d/blacklist.conf setting blacklist ipv6
 
I also disabled these lines in /etc/hosts to avoid confusions:
...
## The following lines are desirable for IPv6 capable hosts
#::1 localhost ip6-localhost ip6-loopback
#fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters
#ff02::3 ip6-allhosts

disabled these lines in /etc/avahi_daemon.conf too :
...
/etc/avahi/avahi-daemon.conf -> say use-ipv6=no

BIND. Ensure listen-on-v6 { none; }; in /etc/bind/named.conf.options. Restart bind9.


APACHE2. Ensure Listen 0.0.0.0:80 in /etc/apache2/ports.conf file. Restart apache2.


Just add this option to your kernel boot line:
ipv6.disable=1 (Press e to edit at the grub boot screen ...)

NTP. Ensure -4 option is set in /etc/default/ntp (e.g. NTPD_OPTS='-4 -g'). Restart ntp.

If you like that, you can put this in /etc/default/grub:

GRUB_CMDLINE_LINUX="ipv6.disable=1"

and then run update-grub

The next time the system boots it will have ipv6 disabled. Let verify it with:

netstat -tunlp

Here is a sample output:

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address     Foreign Address   State       PID/Program name
tcp        0      0 192.168.10.2:53   0.0.0.0:*         LISTEN      895/named       
tcp        0      0 127.0.0.1:53      0.0.0.0:*         LISTEN      895/named       
tcp        0      0 0.0.0.0:22        0.0.0.0:*         LISTEN      734/sshd        
tcp        0      0 127.0.0.1:953     0.0.0.0:*         LISTEN      895/named       
udp        0      0 192.168.10.2:53   0.0.0.0:*                     895/named       
udp        0      0 127.0.0.1:53      0.0.0.0:*                                     





Finally I restarted the server.

shutdown -r now

lsmod|grep ipv6

Wireless on Debian HOW TO

Broadcom BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227, BCM43228 devices (wl) on Debian

    The proprietary Broadcom wl driver (aka broadcom-sta) provides support for some Broadcom-based PCI hardware. It includes a binary-only component targeted for the x86 or x86-64 architecture. Supported devices are listed at the end of this page.

     The BCM4313, BCM43224 and BCM43225 chipsets are alternatively supported by the brcm80211 driver.

Instalation :

Wheezy

1.Add a "non-free" component to /etc/apt/sources.list, for example:
# Debian Wheezy/7.0 testing
deb http://ftp.us.debian.org/debian squeeze main non-free contib
deb-src http://ftp.us.debian.org/debian squeeze main non-free contib

2.Update the list of available packages. Install the Module-Assistant and Wireless-Tools package.
              # aptitude update

          # aptitude install module-assistant wireless-tools

3.Build and install a broadcom-sta-modules-* package for your system, using Module-Assistant: 

          # m-a a-i broadcom-sta

if something wrong with your installation, just install Realtek Firmware :

# aptitude install firmware-realtek

4.Blacklist the brcm80211 module, to prevent it conflicting for support of BCM4313, BCM43224 and BCM43225 devices:

# echo blacklist brcm80211 >> /etc/modprobe.d/broadcom-sta-common.conf

5.Rebuildyour initial ramdisk, to blacklist modules defined at /etc/modprobe.d/broadcom-sta-common.conf within initramfs:  

# update-initramfs -u -k $(uname -r)

6.Unloaad conflicting modules:

# modprobe -r b44 b43 b43legacy ssb brcm80211

7.Load the wl module:

# modprobe wl

8.Verify your device has an available interface:  

# iwconfig

9.Reebot your System n you will see wifi confirmation that your connection can estabilished show on Network Manager 

#shutdown -r now

Module Assistant on Debian How To

Module Assistant on Debian

module-assistant (often abbreviated as m-a) can be used in command line or in interactive mode :

To keep it simple, we run all the commands as root,

so open a terminal as root

in Gnome Application menu/Accessories/Root Terminal.

or KDE menu/System/More Applications/Terminal Program - Super User Mode.

First we need to install module-assistant (you can re-run that command if you aren't sure).

apt-get install module-assistant

Then we get module-assistant to download the headers corresponding to the current kernel, and other 'build-essential' tools... simply run :

m-a prepare

Update list of module :

      m-a update

INTERACTIVE MODE

     If you don't like typing commands, you can run module-assistant in interactive mode. simply type : 

m-a

     This will take you to a menu with the options: Overview, Update, Prepare, Select and Exit. Prepare will configure and install any packages you need in order to compile kernel modules (e.g. kernel headers, gcc, etc). The Select menu takes you to a screen where you can select which modules you want to compile.

m-a -t list | grep -E '^[^ ].*\(' | cut -d " " -f 1 | sort

If you want the package description, use:

for x in $( m-a -t list | grep -E '^[^ ]\

.*(' | cut -d " " -f 1 | sort ) ;\

do  echo Package: $x ; (apt-cache show $x |\

grep -E '^(Description|Package| )' ) \

2>&1  ; echo  ; done | uniq  > /tmp/m-a

IPTABLES on Debian ?? HOW TO

Installing IPTABLES on Debian ::

install required component, all done with one command :

aptitude update && aptitude -u full-upgrade && aptitude install iptables && aptitude clean

or u can check the cache that the programs installed correctly on your machine :

                 dpkg -l iptables

n u will see the screenshot like this :

and seewhere is the places that already installed :

if you cannot see that, then it done with :

                 apt-get update && apt-get install iptables

now, we need to create test rules.,

                 nano /etc/iptables.angel.rules

you can downloads my rules from this site

store them :

                   iptables-restore < /etc/iptables.angel.rules

and :           iptables -L

if you satisfied with that, now we need to save them :

                    iptables-save > /etc/iptables.devil.rules

and init the scripts on network interfaces 

                     nano /etc/network/if-pre-up.d/iptables

inside if.pre.up file you create, insert :
  #!/bin/bash
  /sbin/iptables-restore < /etc/iptables.devil.rules

and now we make it exetutable

                      chmod +x /etc/network/if-pre-up.d/iptables

we must add too the scripts on network configurations :

                      nano /etc/network/interfaces

and insert : "pre-up iptables-restore < /etc/iptables.devil.rules"

after two files, look at screenshot :

done.!!
