MEMBUAT DNS SERVER DENGAN FEDORA8
Prosesnya begini:
-
Interface Network card yang digunakan dipastikan sudah terkonfigurasi dengan baik (lihat file /etc/sysconfig/network-scripts/ifcfg-eth0)
-
Edit file konfigurasi named (named.conf, sesuaikan dengan konfigurasi Anda! (termasuk lokasinya)
-
Buat file zone untuk domain yang disebutkan (reverse dan resolv-nya)
-
Edit konfigurasi /etc/resolv.conf
-
Jalankan service named
-
Jika hasilnya adalah [OK] maka DNS Server sudah berhasil, jika hasilnya [FAILED] maka harus check error, ketikkan saja command # tail -f /var/log/messages
-
Dan jika masih error terus, bersabar dan berdoalah…
Untuk lebih jelasnya saya sertakan konfigurasi dan langkah-langkah yang saya lakukan:
Catatan: root direktori file konfigurasi saya adalah pada direktori /var/named/ (dengan lokasi ini (chroot) akan lebih aman daripada jika lokasi defaultnya pada /etc (yang sudah diketahui umum), tapi Anda perlu menyesuaikan dengan sistem Anda)
Bagian yang saya tambahkan pada file /var/named/chroot/etc/named.conf:
// ————-
// Resolve DNS
// ————-
zone “linuxer.local” IN {
type master;
file “zone/linuxer.local.zone”; //–> lokasi dan nama file zone
allow-update { key “rndckey”; };
allow-transfer { 192.168.0/26; }; //–> sesuaikan dengan netmask Anda
notify yes;
};
// ————-
// Reverse DNS
// ————-
zone “0.168.192.in-addr.arpa” IN {
type master;
file “zone/0.168.192.in-addr.arpa.zone”;
allow-update { key “rndckey”; };
allow-transfer { 192.168.0/26; };
notify yes;
};
include “/etc/named.primary.conf”; //–> menyertakan konfigurasi untuk virtual domain
Setelah itu saya membuat file dengan nama named.primary.conf yang saya letakkan pada direktori /var/named/chroot/etc yang menyatakan konfigurasi untuk virtual domain (maksud saya adalah agar memudahkan untuk menambah berapapun jumlah domain yang diinginkan):
Berikut sebagian (2 virtual domain) dari isi file /var/named/chroot/etc/named.primary.conf:
// —————————-
// Virtual domain fxekobudi.local
// —————————-
zone “fxekobudi.local” IN {
type master;
file “zone/fxekobudi.local.zone”;
allow-update { key “rndckey”; };
allow-transfer { 192.168.0/26; };
notify yes;
};
// —————————-
// Virtual domain forum.local
// —————————-
zone “forum.local” IN {
type master;
file “zone/forum.local.zone”;
allow-update { key “rndckey”; };
allow-transfer { 192.168.0/26; };
notify yes;
};
Setelah saya simpan, saya buat direktori untuk file zone domain dan virtual domain pada /var/named/chroot/var/named/ dan merubah permissionnya dengan perintah:
[root@server nafis]# mkdir /var/named/chroot/var/named/zone
[root@server nafis]# chown named.named /var/named/chroot/var/named/zone
Pada direktori zone tersebut saya letakkan file zone untuk domain, salah duanya adalah:
/var/named/chroot/var/named/zone/linuxer.local.zone (untuk resolve address)
$TTL 86400
@ IN SOA ns.linuxer.local. root.linuxer.local. (
77 ; Serial
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns.linuxer.local.
IN MX 10 mail.linuxer.local.
ns IN A 192.168.0.44
mail IN CNAME ns
www IN CNAME ns
ftp IN CNAME ns
proxy IN CNAME ns
(Setelah disimpan, rubah permission file di atas dengan menjalankan command berikut:
# chown root.named * )
/var/named/chroot/var/named/zone/0.168.192-in.addr-arpa.zone (untuk reverse address)
$TTL 86400
@ IN SOA ns.linuxer.local. root.linuxer.local. (
77 ; Serial
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns.linuxer.local.
44 IN PTR ns.linuxer.local.
Terakhir, saya rubah file /etc/resolv.conf menjadi:
search linuxer.local
nameserver 192.168.0.44
Dan terakhir lagi, saya jalankan service named saat itu juga:
[root@server nafis]# /sbin/service named start
Dan saya aktifkan service named untuk runlevel 3 dan 5 dengan command:
[root@server nafis]# /sbin/chkconfig –levels 35 named on
Dengan demikian pada notebook saya, dengan hanya menggunakan 1 IP address saya bisa memiliki 7 domain yang berbeda (kebetulan saya bikin 7. hehe… Nanti kalau saya bikin ISP sendiri saya akan bikin ribuan domain…)

Install XMMS on Ubuntu ( 8.04 ) Hardy Heron
First: I'm not an Ubuntu user, but I would like to help newbies to get XMMS working on Ubuntu Hardy Heron.Why:
a) A guy entered #xmms on Freenode and wanted to install XMMS on him Ubuntu, so I tried to help him.
b) XMMS is still a good player, and if somebody wants to use it, why not help him?We will install XMMS from source, but there are alternatives though like:
1) change your distro
2) try gutsy packages
OK, let's start
First Step:
We need to download the required packages to compile XMMS
# sudo apt-get install autotools-dev automake1.9 libtool gettext libasound2-dev libaudiofile-dev \libgl1-mesa-dev libglib1.2-dev libgtk1.2-dev libesd0-dev libice-dev libmikmod2-dev libogg-dev \libsm-dev libvorbis-dev libxxf86vm-dev libxml-dev libssl-dev build-essential makeDepending on your internet connection and your machine this may take some minutes.
Second Step:
Prepare the XMMS for compilingCreate a directory in your HOME directory:
# mkdir ~/build
Change the working directory to it:
# cd ~/build
Download XMMS sources:
# wget http://xmms.org/files/1.2.x/xmms-1.2.11.tar.gz
Unpack it:
# tar xvf xmms-1.2.11.tar.gz
Change the working directory to the source directory:
# cd xmms-1.2.11/Third Step:Compiling it:This generates the necessary files, and checks your system:
# ./configure --prefix=/usr
The actually compiling
# make
Fourth Step:
Install it:
# sudo make install
After install we no longer need the source directory:
# cd# rm -rf ~/build
That's it, now we can run XMMS: press ALT+F2 write xmms there and hit enter and enjoy your music.
NOTE: many people say that XMMS is old, buggy,no UTF-8 support, etc. Yes maybe all is true, but it's an audio player not a media library organizer, so it plays music and you listen, that's all and it does that job.
UPDATE:
Flac Plugin
We need to get the build dependencies
# sudo apt-get build-dep flac
You already know what's this ;)
# mkdir ~/build
# cd ~/build
Get flac's sources
# apt-get source flacAnother well known step:)
# cd flac-1.2.1
# ./configure
# make
It's enough to copy the plugin, not to install the whole flac stuff, this is good if will be flac update, note, an update wont break the plugin.
# cp src/plugin_xmms/.libs/libxmms-flac.so ~/.xmms/Plugins
# cd
# rm -rf ~/build

Finishing installation in Progress
Installation complete message here you need to remove your CD select continue and press enter it will reboot your server
After rebooting you can see the following screen prompt for username
This will complete the Ubuntu LAMP Server Installation and your server is ready for installing applications which supports apache,mysql and php.
Configuring Static ip address in Ubuntu server
Ubuntu installer has configured our system to get its network settings via DHCP, Now we will change that to a static IP address for this you need to edit Edit /etc/network/interfaces and enter your ip address details (in this example setup I will use the IP address 172.19.0.10):
sudo vi /etc/network/interfaces
and enter the following save the file and exit
# The primary network interface
auto eth0iface eth0 inet staticaddress 172.19.0.10netmask 255.255.255.0network 172.19.0.0broadcast 172.19.0.255gateway 172.19.0.1
Now you need to restart your network services using the following command
sudo /etc/init.d/networking restart
You need to setup manually DNS servers in resolv.conf file when you are not using DHCP.
sudo vi /etc/resolv.conf
You need to add look something like this
search domain.com
nameserver xxx.xxx.xxx.xxx
GUI Installation for Ubuntu LAMP Server
Option1
If you are a new user and not familiar with command prompt you can install GUI for your ubuntu LAMP server for this you need to make sure you have enabled Universe and multiverse repositories in /etc/apt/sources.list file once you have enable you need to use the following command to install GUI
sudo apt-get update
sudo apt-get install ubuntu-desktop
The above command will install GNOME desktop if you want to install KDE desktop use the following command
sudo apt-get install kubuntu-desktop
Option2
Installing Webmin in Ubuntu Gutsy Gibbon
Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
You can install webmin for your server web interface to configure apache,mysql servers.Now we will see how to install webmin in Ubuntu 8.04
Preparing your system
First you need to install the following packages
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
Now download the latest webmin using the following command
Now we have webmin_1.420_all.deb package install this package using the following command
sudo dpkg -i webmin_1.420_all.deb
This will complete the installation.
Ubuntu in particular don’t allow logins by the root user by default. However, the user created at system installation time can use sudo to switch to root. Webmin will allow any user who has this sudo capability to login with full root privileges.
Now you need to open your web browser and enter the following
https://your-server-ip:10000/
Now you should see similar to the following Screen
After login if you want to configure Apache,Mysql server you need to click on Servers on your lefthand side you should many servers are ready to configure
This is very Easy to configure most of the servers and Enjoy your new Ubuntu Hardy Heron LAMP Server.
Ubuntu Server CD is loading in Progress
Choose your location and press enter you can see we have have selected United Kingdom in the follwoing screen
If you want to try to have your keyboard layout detected by pressing a series of keys you need to select yes option and if you don’t want that and you want to choose from a list click no in this example we have selected no and press enter

Linux sebagai Gateway Internet
Di tutorial jaringan komputer kali ini saya
akan menjelaskan proses installasi linux yang nantinya akan dijadikan sebagai
gateway internet.
Btw, gateway itu
sendiri memiliki definisi sebuah komputer yang melayani konversi
protokol antara beberapa tipe yang berbeda dari suatu network atau program
aplikasi. Sebagai contoh, sebuah gateway dapat meng-convert sebuah paket TCP/IP
menjadi paket NetWare IPX atau dari Apple Talk menjadi DECnet, dan lain-lain. (
Andino-Kamus TI – Ilmukomputer.com )
Gateway inilah
yang nantinya akan menghubungkan jaringan local dalam hal ini LAN dengan
jaringan public yaitu internet.
Sebagai catatan
dalam percobaan ini penulis menggunakan Redhat Linux 9, dan Fedora Core 4. Menggunakan
koneksi ADSL speedy dengan IP Static ( penulis pun bingung, karena baru pertama
kali ini penulis diberikan koneksi ADSL speedy dengan IP Static. :D . Ini
nyata.)
Sebelumnya paket yang
kita butuhkan adalah :
rp-pppoe-3.5-27.i386.rpm
Tapi setahu
penulis paket tersebut sudah terinstall dalam distro tersebut, untuk mengetahui
apakah pake tersebut sudah terinstall didalamnya login sebagai root :
root@alk.root#rpm -qa | grep pppoe
rp-pppoe-3.5-27
Perlu diketahui komputer yang akan dijadikan sebagai gateway nanti
membutuhkan 2 ethernet card nantinya.
Yupz, langsung
aja kita menuju pokok pembahasannya.
Langkah awal yang
harus dilakukan adalah memeriksa apakah kedua ethernet card tersebut sudah
terdetek dengan baik:
root@alk.root#ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:EE:71:11
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

TX packets:35 errors:0 dropped:0
overruns:0 carrier:0

RX bytes:2190 (2.1 KiB) TX bytes:2190 (2.1 KiB)
Yup, jika anda
mendapatkan komentar seperti itu silahkan menuju ke tahap selanjutnya. Jika
tidak ? Silahkan googling :D~~~.
Langkah
berikutnya adalah mengkonfigurasi ethernet card tersebut. Agar nantinya
konfigurasi tersebut dapat dijalankan secara otomatis ketika boot. File
konfigurasi ethernet dalam linux memiliki penamaan ethx, x ini menandakan
pengurutan, jika terdapat 2 ethernet card dalam komputer anda maka, file
konfigurasinya adalah eth0 dan eth1. Letak file konfigurasi secara default
terdapat dalam :
/etc/sysconfig/network-scripts/ifcfg-ethx
Karena nantinya
kita akan menggunakan 2 lancard tersebut, maka file yang akan kita konfigurasi
adalah :
/etc/sysconfig/network-scripts/ifcfg-eth0 dan /etc/sysconfig/network-scripts/ifcfg-eth1
Sebagai contoh,
konfigurasi eth0 yang penulis gunakan adalah sebagai berikut :
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.1.255
HWADDR=00:0C:29:EE:71:11
IPADDR=192.168.1.1
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
TYPE=Ethernet
DEVICE : merupakan
ethernet apa yang akan dikonfigurasi.
BOOTPROTO :
status dari penggunaan ip address, apakah bersifat dynamic ( DHCP ) atau
static.
BROADCAST :
alamat broadcast jaringan yang digunakan.
HWADDR : alamat
fisik dari ethernet card tersebut, biasa disebut Mac Address.
IPADDR : alamat
ip yang nanti akan digunakan oleh gateway linux. Alamat ini yang nantinya akan
berhubungan langsung dengan protol tcp/ip.
NETMASK : subnet
mask yang digunakan oleh device eth0. subnet mask ini digunakan untuk membagi
jaringan menjadi lebih kecil.
ONBOOT : apakah
nanti akan diproses ketika BOOT ??
Dan konfigurasi
eth1 yang digunakan oleh penulis :
DEVICE=eth1
BOOTPROTO=static
BROADCAST=192.168.100.255
HWADDR=00:0C:29:EE:71:1B
IPADDR=192.168.100.1
NETMASK=255.255.255.0
NETWORK=192.168.100.0
ONBOOT=yes
TYPE=Ethernet
Kemudian restart
service network.
root@alk.root#/etc/init.d/network restart
Sebelum ke
langkah selanjutnya, perlu diketahui bahwa, anda diharuskan untuk mengaktifkan
mode bridge pada modem adsl.
selanjutnya adalah konfigurasi ADSL-nya :
root@alk.root#adsl-setup
# pertama kali
akan ditanyakan username yang telah diberikan oleh pihak ISP anda
Enter your Login
Name: 121303xxxxxx@telkom.net
#device yang berhubungan langsung
dengan modem adsl anda, dalam hal ini eth1
INTERFACE
Enter the Ethernet interface connected to the ADSL modem
For Solaris, this is likely to be something like /dev/hme0.
For Linux, it will be ethX, where 'X' is a number.
(default eth0):eth1
karena ketika demand diaktifkan maka anda tidak bisa
# menggunakan IP yang dynamic
# DNS yang digunakan, bagian ini bisa diisi nanti. Lewat saja.
# password yang diberikan oleh ISP anda, berbarengan dengan diberikannya
username tadi
PASSWORD
Please enter your Password:xxxxxxxx
# pemberian akses kepada user
untuk menjalankan/mematikan adsl
USERCTRL
Please enter 'yes' (three letters, lower-case.) if you want to allow
normal user to start or stop DSL connection (default yes):yes
# langkah berikutnya adalah berkenaan dengan firewall disini penulis
memilih no 2
0 - NONE: This script will not set any firewall rules. You are responsible
for ensuring the security of your
machine. You are STRONGLY
recommended to use some kind
of firewall rules.
1 - STANDALONE: Appropriate for a basic stand-alone web-surfing
workstation
2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway
for a LAN
Choose a type of firewall (0-2):2
# apakah
akan dijalankan secara otomatis ketika boot ?
Start this connection at boot time
Do you want to start this connection at boot time?
Please enter no or yes (default no):yes
Dan selanjutnya ketik y saja untuk mensave konfigurasi diatas.
perlu dilakukan. Penulis memberikan sedikit konfigurasi tambahan yang
diletakkan pada file /etc/rc.local
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A POSTROUTING -j MASQUERADE -t nat -s
192.168.1.0/24 -o ppp0
konfigurasi tersebut digunakan
untuk meneruskan paket ip dan melakukan masquerade. Masquerade sendiri
merupakan proses membagi bandwith, karena pada dasarnya isp hanya memberikan
satu koneksi dengan satu ip, maka agar dapat digunakan secara beramai-ramai
maka perlu dilakukan masquerade.
Selanjutnya anda tinggal menambahkan
dns server yang diberikan oleh telkom pada file konfigurasi /etc/resolv.conf, yang penulis gunakan adalah 202.134.0.155.
root@alk.root#echo nameserver 202.134.0.155 >
/etc/resolv.conf
root@alk.root#cat /etc/resolv.conf
nameserver
202.134.0.155
Selanjutnya anda tinggal
menjalankan adsl-start.
Selamat bersurfing ria. :D~
