Gunakan Perintah ini hostnamectl set-hostname new-hostname EKSPERIMEN – June 5, 2009 Mengganti Hostname pada Distro Berbasis Debian Pernahkah ada keinginan dari anda untuk mengganti hostname dari sistem anda. Biasanya ketika kita menginstall misal distro ubuntu hostname kita akan menjadi username-laptop dsb. Nah bagaimana kita mengubahnya? Caranya sebenarnya cukup simple. Buka terminal anda klik Application » Accessories » Terminal lug@username-laptop:~$ sudo gedit /etc/hostname Nah disitu ada nama dari hostname lawas anda, ganti dengan yang baru misal stikom-surabaya. Sistem seharusnya mengupdate otomatis file /etc/hosts karena ada perubahan di /etc/hostname namun untuk memastikan buka saja file tersebut: lug@username-laptop:~$ sudo gedit /etc/hosts Cari string hostname lama anda jika ada lalu ganti ke hostname yang baru.

The Apache2 HTTP Server is a modular program, where we can choose its functionality by including in the server a set of modules. The modules can be statically compiled into the httpd binary when the server is built. Alternatively, modules can be compiled as Dynamic Shared Objects (DSOs) that exist separately from the main httpd binary file. Normally enabling one particular apache DSO module will involve editing the main apache configuration file and adding a LoadModule line to enable the loading of the particular module. Depending from the module itself, we might need to add also some configuration directives. This will work fine on Debian also, but I am going to show you the Debian particular method of managing apache2 modules. Regardless of the apache MPM (Multi-Processing Modules) you are using: apache2-mpm-prefork, … Read entire article »

How to create a self-signed SSL Certificate … … which can be used for testing purposes or internal usage Overview The following is an extremely simplified view of how SSL is implemented and what part the certificate plays in the entire process. Normal web traffic is sent unencrypted over the Internet. That is, anyone with access to the right tools can snoop all of that traffic. Obviously, this can lead to problems, especially where security and privacy is necessary, such as in credit card data and bank transactions. The Secure Socket Layer is used to encrypt the data stream between the web server and the web client (the browser). SSL makes use of what is known as asymmetric cryptography, commonly referred to as public key cryptography (PKI). With public key cryptography, two keys are … Read entire article »

Continuing from the first Apache configuration article, we’ll now look at some of the other settings in the main apache2.conf file and what they can do. Concentrating on efficiency and security, this will end our apache2.conf journey (for now). ServerName Remember that pesky “Could not reliably determine the server’s fully qualified domain name” message when reloading Apache? Let’s get rid of that by defining the ServerName. The ServerName is usually a hostname or a FQDN (Fully Qualified Domain Name). In this case, I am going to use the Slice hostname. It can also be set as ‘localhost’. So open the apache2.conf file: sudo nano /etc/apache2/apache2.conf and add this: ServerName etch Of course, change the hostname to your Slice hostname or a FQDN. Once done, save apache2.conf and gracefully restart Apache (this method of restarting won’t kill open connections): sudo apache2ctl graceful No … Read entire article »
