SuSE有两个命令安装软件，zypper，yast2。

zypper，可以看http://www.ha97.com/2718.html。

不同linux版本，ssh的名字有所差异。所以要确认一下。

zypper search ssh

localhost:~ # zypper search ssh
Loading repository data...
Reading installed packages...

S | Name                           | Summary                           | Type

  | sshfs                          | Filesystem client based on SSH -> | package
  | yast2-sshd                     | YaST2 - SSH Server Configuration  | package

这个时候，可以用

zypper install openssh

yast2 -i openssh

两种方式都是一样。

装完后，编辑vi /etc/ssh/sshd_config

PermitRootLogin yes

PasswordAuthentication yes

还需要设置开机启动

chkconfig sshd on

ssh就设置完了。不过还需要打开防火墙

SuSEfirewall2 stop

就ok，先停止防火墙。

设置VI

SSH登陆后，发现vi没有语法高亮。

cp /etc/vimrc ./.vimrc

退出，再登陆就ok，非常方便。

设置防火墙

http://os.51cto.com/art/200911/165774.htm

vi /etc/sysconfig/SuSEfirewall2

搜索FW_SERVICES_EXT_TCP

加上22端口就ok。

启动防护墙

SuSEfirewall2 start
