5 Jurus Bermain Gitar

Minimnya skill bermain gitar membuat suasana fellowship di berbagai persekutuan kantor kadang jadi kaku dan kurang bergairah. Skill semacam ini memanng tidak hanya didapat dalam waktu singkat. Tapi 5 jurus singkat gL! di hawah ini mungkin dapat membantu jika Anda melatihnya secara konsisten selama minimal 3 hulan, dan setiap harinya selamma 1 hingga 2 jam.

Jurus 1: jangan Lupa Kunci

Kunci adalah nyawa dari permainan gitar. Tanpa kunci, meski kita tahu semua jurus ritem, dijamin kita tidak akan pernah tahu bunyinya seperti apa. Pelajarilah semua kunci dasar seperti C, D, E, F, (3, A, B) beserta semua bentuk minor dan #nya (kecuali untuk kunci B memakai bentuk Bb). Biasanya buku tentang kunci-kunci ini dijual bebas di pasaran. Satu tips yang patut diingat, sebenarnya bentuknya begitu-begitu saja. Jangan dibuat pusing dengan nama-nama yang berbeda. Contoh: bila kunci C digeser sejauh 2 fret akan menghasilkan kunci D, padahal bentuknya sama, hanya letaknya yang berbeda.

Jurus 2: Dua Teknik Dasar

PETIKAN: Ketika memetik gitar, tidak perlu membayangkan harus seperti lagu "KKEB"-nya Andre Hehanusa atau "Tears In Heaven"-nya Eric Clapton. Sebaliknya, petiklah dengan sederhana seperti 3 contoh berikut ini:

Perhatikan posisi jari: jari jempol untuk 3 senar bas, sedangkan 3 senar lainnya dipetik oleh 3 jari pada gamhar.
Penyederhanaan: jari jempol=1, jari telunjuk=2, jari tenguh=3 dan jari minis=4.
1. 1-2-3.4.3-2 dengan l berpindah-pindah bas
2. 1-2-3-4-2 dengan 34 dipetik bersamaan
3. 1.234 dengan 234 dipetik hersamaan sebanyak 3x.

Setelah Anda nmencoba ketiganya, GABUNGKAN SEMUA TEKNIK! Memainkan lagu KKEB bukan impian lagi.

RITEM: Ini hal yang sebetulnya sederhana. Kalau pengamen jalanan saja tekniknya bagus, mengapa kita tidak? Alasan utama ketidak-mampuan ini adalah kurangnya latihan. Jika Anda sungguh serius, sisihkan waktu untuk melatihnya minimal 1 jam sehari. Latihan: Untuk ritem sederhananya dibagi menjadi ritem ke bawah dan ke atas. Untuk ke bawah= l dan ke atas=2.
1. 1-1-2-2-1
2. 1-2-2-1-2-2-1

Jurus 3. Jangan Lupa Bawa Buku Nyanyian

Sekarang buku lagu-lagu Praise & Worship yang lazim digunakan dan sudah banyak dijual bebas di pasaran. Biasanya apa yang tertera di buku-buku semacam ini sudah disederhanakan sehingga menyanyikannya pun mudah saja.

Jurus 4: Berlatih Running Chord Untuk Bermazmur

Sebelum kita bisa membawa orang lain agar mengalami saat yang indah dalam memuji & bermazmur bagi-Nya, kita harus mengalaminya terlebih dulu. Cobalah untuk berdiam diri dengan bermazmur bagi-Nya dengan menggunakan running chord 4/4 seperti misalnya (jika bermain di kunci C): C-F, C-AmDm-G, F-Em-Dm-G. Semakin sering dilantunkan, feeling Anda akan semakin terasah dan Anda akan terheran-heran melihat perkembangan skill Anda.

Jurus 5: Percaya Diri

Percaya diri! That's the best thing. Walau Anda banyak melakukan kesalahan (terutama biasanya salah kunci), lanjutkan saja dengan tertawa bersama teman-teman Anda. Dijamin, mereka semua pasti ikut tersenyum. Toh pada akhirnya, bukan permainan gitar/nyanyian kita yang diterima oleh-Nya, tapi kesungguhan hati kita.**

Install DHCP Server di Ubuntu

Dynamic Host Configuration Protocol (DHCP)

The Dynamic Host Configuration Protocol (DHCP) is a network service that enables host computers to be automatically assigned settings from a server as opposed to manually configuring each network host. Computers configured to be DHCP clients have no control over the settings they receive from the DHCP server, and the configuration is transparent to the computer's user.

The most common settings provided by a DHCP server to DHCP clients include:

*

IP-Address and Netmask
*

DNS
*

WINS

However, a DHCP server can also supply configuration properties such as:

*

Host Name
*

Domain Name
*

Default Gateway
*

Time Server
*

Print Server

The advantage of using DHCP is that changes to the network, for example a change in the address of the DNS server, need only be changed at the DHCP server, and all network hosts will be reconfigured the next time their DHCP clients poll the DHCP server. As an added advantage, it is also easier to integrate new computers into the network, as there is no need to check for the availability of an IP address. Conflicts in IP address allocation are also reduced.

A DHCP server can provide configuration settings using two methods:

MAC Address

This method entails using DHCP to identify the unique hardware address of each network card connected to the network and then continually supplying a constant configuration each time the DHCP client makes a request to the DHCP server using that network device.
Address Pool

This method entails defining a pool (sometimes also called a range or scope) of IP addresses from which DHCP clients are supplied their configuration properties dynamically and on a "first come, first served" basis. When a DHCP client is no longer on the network for a specified period, the configuration is expired and released back to the address pool for use by other DHCP Clients.

Ubuntu is shipped with both DHCP server and client. The server is dhcpd (dynamic host configuration protocol daemon). The client provided with Ubuntu is dhclient and should be installed on all computers required to be automatically configured. Both programs are easy to install and configure and will be automatically started at system boot.
Installation

At a terminal prompt, enter the following command to install dhcpd:

sudo apt-get install dhcp3-server

You will probably need to change the default configuration by editing /etc/dhcp3/dhcpd.conf to suit your needs and particular configuration.

You also need to edit /etc/default/dhcp3-server to specify the interfaces dhcpd should listen to. By default it listens to eth0.

NOTE: dhcpd's messages are being sent to syslog. Look there for diagnostics messages.
Configuration

The error message the installation ends with might be a little confusing, but the following steps will help you configure the service:

Most commonly, what you want to do is assign an IP address randomly. This can be done with settings as follows:

# Sample /etc/dhcpd.conf
# (add your comments here)
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.example";

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
range 192.168.1.150 192.168.1.200;
}

This will result in the DHCP server giving a client an IP address from the range 192.168.1.10-192.168.1.100 or 192.168.1.150-192.168.1.200. It will lease an IP address for 600 seconds if the client doesn't ask for a specific time frame. Otherwise the maximum (allowed) lease will be 7200 seconds. The server will also "advise" the client that it should use 255.255.255.0 as its subnet mask, 192.168.1.255 as its broadcast address, 192.168.1.254 as the router/gateway and 192.168.1.1 and 192.168.1.2 as its DNS servers.

If you need to specify a WINS server for your Windows clients, you will need to include the netbios-name-servers option, e.g.

option netbios-name-servers 192.168.1.1;

Dhcpd configuration settings are taken from the DHCP mini-HOWTO, which can be found here.
