原因是
The default is DES-CBC3-SHA which seems that is not supported anymore by FileZilla

NFS quick howto for centos 5
To use nfs successfully, you have to configure the server and the client. In this example, the client is 192.168.0.3 and the server is 192.168.0.1. The folder to be shared is /home/sharing, and to be mounted to /mnt on the client
On the server
- Make directory that you want to use.
- # mkdir /home/sharing
- Edit /etc/exports, insert the client machine’s ip
- # vi /etc/exports
- Add this line:
- /home/sharing 192.168.0.3/255.255.255.255(rw,sync)
- Save
- Edit /etc/hosts.allow
- # vi /etc/hosts.allow
- Add this line:
- portmap: 192.168.0.0/255.255.255.0
- Save
- Start nfs and portmap
- # /etc/init.d /nfs start
- # /etc/init.d/portmap start
On the client
- Start portmap
- # /etc/init.d/portmap start
- Mount the nfs folder
- # mount 192.168.0.1:/home/sharing /mnt
- Check /var/log/messages for any error that might occur
- # tailf /var/log/messages
- Use mount to check if the folder is mounted properly
- # mount
- This should be the output:
- 192.168.0.1:/home/sharing on /mnt type nfs (rw,addr=192.168.0.1)
- Edit /etc/fstab to mount the shared folder on boot
- # vi /etc/fstab
- Add this line
- 192.168.0.1:/mnt/sdb1/backup /mnt nfs rw,hard,intr 0 0
- Save
You can use 'man exports' to see the options available for /etc/exports
以前总觉得苹果的 macbook pro 非常好，觉得matetext是那么Cool。以致于自己都想买一台，可是当自己做为Linux的9年用户得时候，觉得macbook并不是那么神通广大。然而Iphone,也不是那么炫。不是还有Android吗？放弃封闭的，投奔开放吧。
- 方法一：先通过
ctrl-z把程序放到后台，再通过bg %<jobid>提交命令到后台，最后使用disown -h %<jobid>。现在就可以退出终端，程序依然还在运行。 - 方法二：使用screen和retty
$ screen -S my_process
$ retty $(pgrep my_process)
/redraw
mid3iconv
由于Ubuntu中的Amarok等播放器只支持UTF8字符，所以在Amarok中常常出现乱码。解决方案如下：
1 | sudo apt-get install python-mutagen |
修改mp3中编码：
到你的music目录去
1 | find . -iname "*.mp" -execdir mid3iconv -e GBK {} \; |
- htop http://htop.sourceforge.net/
一个可以让用户与之交互的进程查看器。作为文本模式的应用程序，主要用于控制台或 X 终端中。当前具有按树状方式来查看进程，支持颜色主题，可以定制等特性。
安装完Linux一般都会发现快捷键不好用了。
1、简单方法
切入到文本控制台CTRL+ALT+F1
执行 echo crt_enable > /proc/acpi/ibm/video
切回图形界面就可以使用投影仪了。
注：执行前确认 /proc/acpi/ibm/video 存在
如果不存在请往下看。
2、复杂且有效方法

cpulimit
cpulimit 是一个简单而有用的小程序，通过它你可以限制一个进程的 CPU 占用率。如果善加利用，必将成为系统管理员的得力助手。
cpulimit 的用法也很简单，如上图所示，通过 -e 选项指定需控制的进程名（或 -p 选项指定 pid），-l 选项指定 CPU 的占用百分比即可。这里，我将 Chrome 的 CPU 占用率限制到 25%。
cpulimit 可从其项目主页下载，或通过你所用的 Linux 发行版包管理器安装。
The following shortcuts work when using default (Emacs) key bindings. Vi-bindings can be enabled by running set -o vi.
Tab ⇆ : Autocompletes from the cursor position.
Ctrl+a : moves the cursor at the beginning of the line (equivalent to the key Home).
Ctrl+e : (end) moves the cursor at the line end (equivalent to the key End).
Ctrl+p : (previous) recalls the previous command (equivalent to the key ↑).
Ctrl+n : (next) recalls the next command (equivalent to the key ↓).
Ctrl+r : (research) recalls the last command including the specified character(s). A second Ctrl+r recalls the next anterior command which corresponds to the research
Ctrl+s : Go back to the next more recent command of the research (beware to not execute it from a terminal because this command also launches its XOFF). If you changed that XOFF setting, use Ctrl+q to return.
Ctrl+o : executes the found command from research.
Ctrl+l : clears the screen content (equivalent to the command clear).
Ctrl+u : clears the line content before the cursor and copy it in the clipboard.
Ctrl+k : clears the line content after the cursor and copy it in the clipboard.
Ctrl+w : clears the word before the cursor and copy it in the clipboard.
Ctrl+y : (yank) adds the clipboard content from the cursor position.
Ctrl+d : sends an EOF marker, which (unless disabled by an option) closes the current shell (equivalent to the command exit).
Ctrl+c : sends the signal SIGINT to the current task, which aborts and closes it.
Ctrl+z : sends the signal SIGTSTP to the current task, which suspends it. To return to it later one can enter fg ‘process name’ (foreground).
Ctrl+x Ctrl+x : (because x has a crossing shape) alternates the cursor with its old position.
Ctrl+x Ctrl+e : (editor because it takes the $EDITOR shell variable) edits the current line in vi.
Alt+f : (forward) moves forward the cursor of one word.
Alt+b : (backward) moves backward the cursor of one word.
Alt+Del : cuts the word before the cursor.
Alt+d : cuts the word after the cursor.
Alt+u : capitalizes every character from the cursor’s position to the end of the current word.
Alt+l : lowers the case of every character from the cursor’s position to the end of the current word.
Alt+c : capitalizes the character under the cursor and moves to the end of the word.
Alt+r : cancels the changes and put back the line as it was in the history.
