安裝服務(wù)器端的openssh
- 安裝 open ssh：
- 輯配置文件，允許以 root 用戶通過 ssh 登錄：
sudo vi /etc/ssh/sshd_config
找到：PermitRootLogin prohibit-password禁用
添加：PermitRootLogin yes
執(zhí)行命令：sudo service ssh restart
安裝openssh-server過程中，如若出現(xiàn)以下提示：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package openssh-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
這個問題的原因是ubuntu的/etc/apt/source.list中的源比較舊了，需要更新一下，更新方法：
$ sudo apt-get -y update
