Membuat multiple domain dalam satu DNS Server

Agar sebuah server bisa dipanggil dengan nama domain yang berbeda maka perlu diset DNS servernya. Berikut saya berikan link sbb : https://lists.isc.org/pipermail/bind-users/2007-September/067540.html tulisan dari Mr. Tek Bahadur Limbu.

Adapun configurasi di server saya pada file /etc/bind/named.conf.default-zones sbb :
// prime the server with knowledge of the root servers
zone “.” {
type hint;
file “/etc/bind/db.root”;
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone “smkintegral.sch.id” {
type master;
file “/etc/bind/db.coba”;
};

zone “smk.com” {
type master;
file “/etc/bind/db.coba”;
};
zone “4.168.192.in-addr.arpa” {
type master;
file “/etc/bind/db.ip”;
};
zone “0.in-addr.arpa” {
type master;
file “/etc/bind/db.0″;
};

zone “255.in-addr.arpa” {
type master;
file “/etc/bind/db.255″;
};

Dengan setting DNS server seperti itu maka web server saya dapat dipanggil dengan dua domain yaitu www.smkintegral.sch.id dan www.smk.com.

Selamat mencoba, Salam Linux.

Download menggunakan wget melewati proxy server

Dengan adanya Proxy server di gateway jaringan anda maka beberapa fitur jaringan akan bermasalah. Antara lain Synaptic Package Manager dan Wget. Contoh ketika saya menggunakan wget target IPnya malah belok ke IP Client tertentu dan portnya juga tertentu sehingga download menggunakan wget menjadi gagal. Setelah browsing akhirnya mendapatkan inspirasi dari link berikut ini. Langkah pertama adalah men-setting lingkungan dengan perintah :

$ export http_proxy=”http://192.168.4.35:8080″

Ket : IP Proxy server=192.168.4.35, Port Proxy=8080.
Setelah itu test download menggunakan wget :
wget http://smkintegral.sch.id/~tamu/simoncelli.jpg

Connecting to 192.168.4.35:8080… connected.
Proxy request sent, awaiting response… 200 OK

Install firefox dan libreoffice di debian squeeze

For my desktop use, I wanted to keep my office suite and web browser updated while continuing to run Debian stable as my base. Here is how to install the latest Firefox and Libreoffice packages on Squeeze.

Download Firefox 4 here. Then as root:
Code:
mv firefox*.tar.bz2 /opt
cd /opt
tar -xvjf firefox*.tar.bz2
ln -s /opt/firefox /usr/local/firefox4
ln -s /usr/local/firefox4/firefox /usr/local/bin/firefox4
rm firefox*.tar.bz2
Firefox 4 can now be run as normal user with command “firefox4″. or “/usr/local/bin/firefox4″. In Gnome, you can add Firefox to the application menu by:

1. right click Applications menu
2. select “edit menus”
3. click on “Internet”
4. select “new item”: Type: Application, Name: Firefox, Command: /usr/local/bin/firefox4
5. To add the Firefox icon in the menu, it is located in: /opt/firefox/icons/mozicon128.png

I just tested it, and it works well, including my plugins and bookmarks from Iceweasel.

Download Libreoffice here. Choose the deb version, then:
Code:
tar -xzf LibO_3*.tar.gz
cd LibO_3*/DEBS/
su
dpkg -i *.deb
cd desktop-integration
dpkg -i *.deb
It will install Libreoffice in /opt and the packages will show up in Synaptic Package Manager under “Local”. The installation automatically creates menu entries in Gnome for Libreoffice applications.

I’ve had no problems thus far using the latest Libreoffice 3.2.2 and Firefox 4. Hope this is helpful for anyone else wanting to install.

youtube-dl akhirnya bekerja kembali, good job linux.

original url : http://www.webupd8.org/2010/07/update-youtube-dl-to-get-it-working.html

YouTube keeps making changes to the website which breaks all YouTube download applications, including my favourite YouTube downloader called “youtube-dl”. For this reason, we’ve backported the Maverick version for Ubuntu Karmic and Lucid users – and the updated version is available in the WebUpd8 PPA.

But before you install the latest youtube-dl, a little info on this amazing YouTube command line donwloader.

youtube-dl is a python script (comes in a .deb) for downloading videos from YouTube. The recent versions also support downloading videos from video.google.com, photobucket, dailymotion, and metacafe.

But it’s not just fixing YouTube that’s new in the latest youtube-dl. Here are some recent changes which are not in the Lucid version of youtube-dl:

• add preliminary support for Dailymotion videos
• support for WebM formats (vp8 + vorbis)
• support for youtu.be URLs
• add support for the “original” video format in YouTube
• add a –max-quality option

And a lot more.

I’m not sure, but you might have to add the Gstreamer PPA for WebM support.

To install the latest youtube-dl in Ubuntu 10.04 Lucid Lynx and 9.10 Karmic Koala (but I’ve only tested it in Lucid), run the following commands in a terminal:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install youtube-dl

You can also manually download the .deb files if you want.

Using youtube-dl is very easy. To download a YouTube video, use the following command:

youtube-dl YOUTUBE-URL

where YOUTUBE-URL is the exact link to the YouTube video, like this (just an example): http://www.youtube.com/watch?v=BF14bWw1NKk

You can download all the available formats, like this:

youtube-dl --all-formats YOUTUBE-URL

For advanced options, type:

youtube-dl --help
