1. 安装Ubuntu Server版本 | |
2. 更新软件源 | |
sudo apt-get update | |
3. 安装open-ssh | |
sudo apt-get install openssh-server | |
4. 提升ssh认証时间 | |
步骤一 关闭ssh的gssapi认证 | |
vi /etc/ssh/ssh_config | |
注释掉如下两行 | |
GSSAPIAuthentication yes | |
GSSAPIDelegateCredentials no | |
步骤二 关闭ssh的UseDNS | |
vi /etc/ssh/sshd_config | |
注:ubuntu的sshd_config文件没有UseDNS参数,而据我了解,其它类*NIX、*BSD操作系统的sshd_config都有UseDNS参数,且它们缺省都是"UseDNS yes", | |
那估计ubuntu的sshd_config虽然没有UseDNS,那它缺省也是"UseDNS yes"了 | |
于是,在sshd_config末尾处插入如下行 | |
UseDNS no | |
然后执行指令"/etc/init.d/ssh restart",重启ssh服务,配置生效 |
