Customer site to deploy software, discover what's special to me real system also cleaner than my trouser pocket ah, then including the network, I can only say that I was too young. The first step was to configure ssh main card, but fortunately can mount CD / DVD file, the following record some of my deployment, For me and for you like me!

Software Deployment

Preparing two machines
A machine: even outside the network can
machine B: not even outside the network

install openssh

Read many online articles, many of which were required to download the four good openssh package installed, then dpkg -i *.debinstall, but if you give the customer is a clean system, so there is little of this deployment with eggs. According to the installation that way, the basic package will install missing dependencies failed. Here I talk about my installation process it
A machine:

# 在A机器上更新缓存相关的依赖包
sudo apt-get -d update
# 缓存openssh-server包
sudo apt-get -d install openssh-server
# 进入到缓存目录
cd /var/cache/apt/archives
# 先在A机器上测试安装
dpkg -i *.deb
# 安装完毕后查看是否安装成功
sudo service ssh status
# 也可以去/etc/ssh目录下看看是否有sshd_config文件
# 如果安装成功，那么将所有的deb包打包成tar.gz文件
tar -czvf ssh.tar.gz *.deb

B machine:

1. Ssh.tar.gz use UltraISO tool to convert files into iso files

2. In your virtual machine's configuration, select CD / DVD, check connected, that you choose your iso file. (This can also add a CD / DVD device)
   

3. Mount iso file

   # 如果之前挂接过，先解除挂载
   sudo umount /dev/sro
   # 挂载光驱
   sudo mount /dev/sr0 /mnt
   cd /mnt
   # 拷贝之前打包的ssh.tar.gz文件到你指定的目录
   cp ssh.tar.gz /home/
   

4. Extracting installer

   tar -zxvf ssh.tar.gz
   cd ssh
   dpkg -i *.deb
   

ssh service configuration

1. Modify / etc / ssh / ssh_config file

   将Port 22前面的#注释删掉
   将PasswordAuthentication yes前面的#注释删掉
   

   

2. Modify / etc / ssh / sshd_config file

   将Port 22前面的#注释删掉
   将PasswordAuthentication yes前面的#注释删掉
   

   The PS : using vim, they can be used in the normal mode /to match the query, to quickly locate the corresponding string.

3. Restart Service

   sudo service ssh restart
   

4. Using the xftptool connection test, skip this step

Done, O (∩_∩) O ~ ha

Problem Record

1. ssh connection is slow

   # 以root用户运行
   sudo su
   # 1.编辑/etc/ssh/sshd_config文件
   vi /etc/ssh/sshd_config
   # 2.在里面加入UseDNS no
   # 3. 在里面取消注释GSSAPIAuthentication no
   # 保存编辑
   wq
   # 重启服务
   service sshd restart
