wireshark permission ( no interface list) on Ubuntu for non-superuser

wireshark權限


直接使用官網的方法 
一行搞定
sudo setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap



其它:
1. 法一: 重新設定 wireshar, 它會詢問是否允許non-super user抓封包, 允許即可使用

$ sudo dpkg-reconfigure wireshark-common 
$ sudo usermod -a -G wireshark $USER
$ sudo reboot

2. 法二: 建新群組, 讓此群組的人才可抓封包

sudo addgroup -system wireshark
sudo chown root:wireshark /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
sudo usermod -a -G wireshark $USER

除了黑色永遠偏紫外，在Ubuntu下另一個困擾我己久的問題就是 chrominum-browser的網址列跟標題列遇到中文會亂碼 （可正常使用中文但顯示上是亂碼）

避免文章消失，在此備份一下

PS 設定居然是html語法，打完內文變超怪 lol

Ubuntu 14.04的調校

ibus的浮動視窗真的滿煩人的

http://www.ubuntu-tw.org/modules/newbb/viewtopic.php?topic_id=85988

Ubuntu 10.04後的紫黑色調改黑色大整理, change the purple black to real black

Ubuntu 10.04後的紫黑色改黑色大整理XD, 
自10.04後採用plymouth, 所以10.04後皆可用此設定

1. Define the black to real black.
把黑色定義改回真正的黑色

*sudo apt-get install gksu
* sudo gksu gedit /lib/plymouth/themes/text.plymouth 

#change black value with your color, in my case #000000 is black
black=0x000000

2. Change boot splash into black and white
把開機 logo弄成黑白色系

* sudo nano /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.script

#change the following 2 lines that can be found to something like this
Window.SetBackgroundTopColor (0.0, 0.00, 0.0); # Nice colour on top of the screen fading to
Window.SetBackgroundBottomColor (0.0, 0.00, 0.0); # an equally nice colour on the bottom

*sudo update-initramfs -u

*sudo nano /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.grub
#change the digits in "if background_color 44,0,30" to
if background_color 0,0,0


*sudo update-grub

3. Login screen background and the definition of black
登入畫面的紫黑色要用deb-editor改

* sudo apt-get install dconf-editor
*sudo su
*xhost +SI:localuser:lightdm
*sudo su lightdm -s /bin/bash
*dconf-editor

#com->conical->unity-greeter and
change background-color to #000000 ( For Black )

在dconf-editor中, 除了把黑色改全0, 也可把登入畫面背景圖順便改掉

background的值可以改/usr/share/backgrounds/Ibanez_Infinity_by_Jaco_Kok.jpg

4. Console background
console 改背景, 在 profile preference 中的color分頁改背景/字的顏色
如果要改豆沙色, 色碼 #C7EDCC
