ubantu 16.04 config nfs / ssh / proxy

一 NFS

1.sudo apt-get install nfs-kernel-server 安装nfs.

2.sudo mkdir /home/share/nfs 建立nfs共享文件夹.

3.sudo vi /etc/exports 配置nfs

在文档的最后一行加入/home/song/nfs *(rw,sync,no_root_squash,no_subtree_check)，保存退出。

4.sudo /etc/init.d/rpcbind restart 重启rpcbind

5.sudo /etc/init.d/nfs-kernel-server restart 重启nfs

6.sudo mount -t nfs 10.67.112.182:/home/share/nfs 在目标机中挂载服务器的共享文件夹,把以上指令写到/etc/rc.local 当中可实现开机自动挂载

二 SSH

1. 安装ssh server ,开一个终端输入如下命令：

sudo apt-get install openssh-server

2. 之后，查看ssh 的状态：

sudo service ssh status

3. 你也看要通过修改如下的文件来改变默认的端口等信息的配置:

sudo nano /etc/ssh/sshd_config

On Ubuntu desktop, you may use gedit instead of nano:

4.最后重启服务应用新的配置信息:

sudo service ssh restart

 

三 proxy

1.Ubuntu 12.04 LTS and Newer Automatic Shell Script

The following shell script will set up Intel proxies on Ubuntu. The script has been tested on Ubuntu 12.04, 14.04, 16.04.2, and 18.04, but will probably work on other versions as well. Run it as follows:

 wget --no-proxy --no-check-certificate https://intelpedia.intel.com/images/8/88/Setup_intel_proxy.sh.zip
 unzip Setup_intel_proxy.sh.zip
 chmod +x setup_intel_proxy.sh
 sudo ./setup_intel_proxy.sh

Matthew Fernandez: why does the above script set include 134.134.0.0/16 in no_proxy? At first I thought this was a mistake and it was supposed to be the private rage 172.16.0.0/12 (which is also missing), but after looking up 134.134.0.0/16 it seems this might be a range assigned to Intel in Hillsboro. Is this range universally reachable without a proxy for users outside US?

Proxy Environment Variables to set

Linux/UNIX/MinGW users who are using clients not capable of auto-configuration will want to define these environment variables.

 export http_proxy=http://proxy-chain.intel.com:911
 export https_proxy=http://proxy-chain.intel.com:912
 export ftp_proxy=http://proxy-chain.intel.com:911
 export socks_proxy=http://proxy-us.intel.com:1080
 export no_proxy=intel.com,.intel.com,localhost,127.0.0.1

On OpenSuse or SLES look at /etc/sysconfig/proxy or use yast proxy, on other platforms consider modification of /etc/environment or ~/.bashrc

Manual Configuration

• Edit the /etc/environment file

 sudo vi /etc/environment

• Copy the following lines in the file:

 http_proxy=http://proxy-chain.intel.com:911
 https_proxy=http://proxy-chain.intel.com:912
 ftp_proxy=http://proxy-chain.intel.com:911
 socks_proxy=http://proxy-us.intel.com:1080
 no_proxy=intel.com,.intel.com,localhost,127.0.0.1

• Save the file.
• Let's make the Proxy available every time that we use sudo
• Edit the /etc/sudoers file with visudo. To use nano, instead run sudo EDITOR=nano visudo /etc/sudoers.

 sudo visudo -f /etc/sudoers

• Find entry:

 Defaults        env_reset

• Below add

 Defaults        env_keep += "http_proxy https_proxy ftp_proxy socks_proxy no_proxy"

• Edit the /etc/apt/apt.conf file

 sudo vi /etc/apt/apt.conf

• Add the following lines:

 Acquire::http::proxy "http://proxy-chain.intel.com:911";
 Acquire::https::proxy "http://proxy-chain.intel.com:912";
