Ubuntu 14.04.2 Server + BIND DNS Server + SIP DNS SRV settings

step 1.

Download Ubuntu Server 14.04.2 and install this system.
http://www.ubuntu.com/download/server


Installation process
To select the “DNS Server” service function.


step 2.

Install Webmin On Ubuntu 14.04 LTS using official repository

Add the webmin official repository:

Edit file /etc/apt/sources.list,

sudo nano /etc/apt/sources.list

Add the following lines:

 

deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib

Add the GPG key:

sudo wget http://www.webmin.com/jcameron-key.asc
sudo apt-key add jcameron-key.asc

Update the sources list:

sudo apt-get update

Install webmin using the following command:

sudo apt-get install webmin

Allow the webmin default port “10000” via firewall, if you want to access the webmin console from a remote system.

sudo ufw allow 10000

Access Webmin console

Open up your browser and navigate to the URL https://ip-address:10000/. The following screen should appear. Enter the user name and password to log in to webmin console.

step 3.

使用 Webmin方式來設定DNS Server

設定 Bind 8 可以接受外部連線及轉送查詢的伺服器。
「伺服器」->「BIND 8 DNS 伺服器」->「Edit Config File」->/etc/bind/named.conf.options
在此檔中加入
 
listen-on port 53 { any; };
forwarders {
        163.168.168.59;   //base DNS IP
        8.8.8.8;  //google DNS IP

        };
    allow-query {
        any;
        };

設定區域預設值

「伺服器」->「BIND 8 DNS 伺服器」->「區域預設值」
「預設的區域設定」->「允許從 ... 的查詢」點擊「監聽」及輸入 [any]
 






建立一個新的主控區域-正向
輸入管理網域名稱 test.local

 

建立 Address 紀錄(位址)

 增加 Address 紀錄
 

step 4.

使用nslookup指令查詢

nslookup
server "DNS Server IP"
set type=srv
_sip._udp.test.local
 

[office] libreoffice Calc 工作表字體太小

修改主题的gtkrc文件。
比如：
sudo gedit /usr/share/themes/elementary/gtk-2.0/gtkrc

找到GtkScrollbar ::slider-width，
修改成適合的值。
如原先是6，我改為18後.儲存檔案退出，
重新開啟libreoffice Calc，此時下方的工作表字體便會放大。

style "murrine-default" {        GtkScrollbar        ::has-backward-stepper              = 0     GtkScrollbar        ::has-forward-stepper               = 0     GtkScrollbar        ::min-slider-length                 = 30     GtkScrollbar        ::slider-width                      = 18     GtkScrollbar        ::trough-border                     = 1

[Ubuntu] Install Intel Graphics Installer ver 1.0.7 in 14.10.

Intel(R) Graphics Installer for Linux* 1.0.7

https://01.org/linuxgraphics/downloads/2014/intelr-graphics-installer-linux-1.0.7


“Distribution not supported” in 14.10

That software checks /etc/lsb-release and that is a text file we can edit ourself so it might be fairly easy to circumvent. Make a backup first though if you do not know what this means. From a command line:

sudo cp /etc/lsb-release /etc/lsb-release.backup

And then edit the file ...

sudo gedit /etc/lsb-release

And change the lines that look like

DISTRIB_RELEASE=14.10
DISTRIB_CODENAME=utopic

with ...

DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty

And save it. Start the installation and it should finish this time without a notice regarding the distribution.

After that you can then put back the backup file with (cp to leave the backup, change it to mv to also remove the backup)...

sudo cp /etc/lsb-release.backup /etc/lsb-release
