 在A上执行keygen,转换后cp到B上,那么在B上ssh A时不需要口令
 §6.4 使用Public Key (OpenSSH) 不用密码登陆.
 步骤如下:
 l         创建key
 .           $ mkdir -p ~/.ssh                        If it doesn't already exist
 .           $ chmod  ~/.ssh
 .           $ cd ~/.ssh
 $ ssh-keygen -t dsa
 l         拷贝key到服务器端
 $ scp -p id_dsa.pub remoteuser@remotehost:
 Password: ********
 l         登陆到服务器端安装公钥
 $ ssh -l remoteuser remotehost
 Password: ********

 remotehost$ mkdir -p ~/.ssh                        If it doesn't already exist
 remotehost$ chmod  ~/.ssh
 remotehost$ cat id_dsa.pub >> ~/.ssh/authorized_keys   (Appending)
 remotehost$ chmod  ~/.ssh/authorized_keys
 remotehost$ mv id_dsa.pub ~/.ssh        可选步骤,该文件甚至可以删除掉
 remotehost$ logout
 l         用public-key登陆
 $ ssh -l remoteuser remotehost
 Enter passphrase for key '/home/smith/.ssh/id_dsa': ********

 公钥一般存放在~/.ssh/authorized_keys, 老的OpenSSH版本可能存放在~/.ssh/authorized_keys2.

 Public-key 认证机制比密码要安全, 因为密码不在网络上传输. 而且可以是用加密的方式存储的,如果没有别人没有passphrase,拿到密钥也没有用.为此一定要设置passphrase

 如果以上不步骤不能实现不输密码登陆,请检查:
 /etc/ssh/sshd_config:
 PubkeyAuthentication yes           If no, change it and restart sshd
 可以用ssh –v来显示详细的登陆过程.

 SSH- key文件格式:
 SSH的两种主要实现方式: OpenSSH and SSH Secure Shell ("SSH2")
 OpenSSH 的如下:
 ssh-dss A9AAB3NzaC1iGMqHpSCEliaouBun8FF9t8p...
 or:
 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEA3DIqRox...
 SSH Secure Shell的如下:
 ---- BEGIN SSH2 PUBLIC KEY ----
 AAAAB3NzaC1kc3MAAACBAM4a2KKBE6zhPBgRx4q6Dbjxo5hXNKNWYIGkX/W/k5PqcCH0J6 ...
 ---- END SSH2 PUBLIC KEY ----

 SSH Secure Shell的安装方式也不同,目录在~/.ssh2 要在, ~/.ssh2/authorization中用如下方式提及: Key public_key_filename. 私钥也需要在~/.ssh2/identification用如下方式引用:
 IdKey private_key_filename
  

使用Public Key (OpenSSH) 不用密码登陆

 AIX6.1默认是没有安装SSH服务的，要使用SSH连接AIX服务器，必须手动安装OpenSSH软件。

 .在IBM官方网站下载Openssl和OPenSSH软件(可下载本文附件)。
 .将下载的软件上传至AIX系统/tmp目录下。
 .解压软件

     bash-3.2# uncompress openssl-fips-12.9.8.1801.tar
     bash-3.2# tar xvf openssl-fips-12.9.8.1801.tar
     x openssl-fips-12.9.8.1801
     x openssl-fips-12.9.8.1801/openssl.base,  bytes,  media blocks.
     x openssl-fips-12.9.8.1801/openssl.license,  bytes,  media blocks.
     x openssl-fips-12.9.8.1801/openssl.man.en_US,  bytes,  media blocks.

     bash-3.2# uncompress OpenSSH_5.8.0..tar.Z
     bash-3.2# cd OpenSSH/
     bash-3.2# tar xvf OpenSSH_5.8.0..tar 

 OS:AIX 5.3.
 -------------------------------------安装openssl----------------------------------
 .下载openssl
 https://www14.software.ibm.com/webapp/iwm/web/reg/download.do?source=aixbp&S_PKG=openssl&lang=en_US#
 选择OpenSSL Install images v0.9.8. ( OpenSSL 0.9.8r ) for AIX 5.3 , AIX 6.1 & 7.0

 .解压缩安装包
 [hxl/root]#ls - openssl-0.9.8.1802.tar.Z
 openssl-0.9.8.1802.tar.Z
 [hxl/root]#uncompress openssl-0.9.8.1802.tar.Z

 .查看tar的内容
 [hxl/root]#tar -vtf openssl-0.9.8.1802.tar
 drwxr-xr-x             Jun  ::  openssl-0.9.8.1802/
 -rw-r-----       Jun  ::  openssl-0.9.8.1802/openssl.base
 -rw-r-----          Jun  ::  openssl-0.9.8.1802/openssl.license
 -rw-r-----       Jun  ::  openssl-0.9.8.1802/openssl.man.en_US
 [hxl/root]#mkdir opensshl
 [hxl/root]#mv openssl-0.9.8.1802.tar ./openssh1
 [hxl/root]#tar -xvf openssl-0.9.8.1802.tar

 .安装
 smitty install指定软件的目录,选择安装:openssl.base
 ACCEPT new license agreements? 选择YES

 ---------------------------安装openssh-----------------------------------
 .下载openssh,下载地址:http://sourceforge.net/projects/openssh-aix/files/
 [hxl/root]#ls - openssh_5.2p1_aix53.tar.z
 openssh_5.2p1_aix53.tar.z

 .修改文件名,将后缀小写的z改为大写,然后解压缩
 [hxl/root]#mv openssh_5.2p1_aix53.tar.z openssh_5.2p1_aix53.tar.Z
 [hxl/root]#uncompress openssh_5.2p1_aix53.tar.Z

 .查看tar文件内容
 [hxl/root]#tar -vtf openssh_5.2p1_aix53.tar

 解压到当前目录
 [hxl/root]#mv openssh_5.2p1_aix53.tar ./openssh
 [hxl/root]#tar -xvf openssh_5.2p1_aix53.tar

 .安装
 smitty install指定软件软件存放的目录,选择openssh.base
 ACCEPT new license agreements? 选择YES

 ------------------------------------运行ssh服务--------------------------
 .运行ssh服务
 默认安装好后系统自动启用ssh服务：
 [hxl/root]#lssrc -a | grep ssh
  sshd             ssh                     active

 启动sshd服务
 [hxl/root]#startsrc -s sshd

 停止sshd服务
 [hxl/root]#stopsrc -s sshd

 这样就可以通过putty或则ssh登陆了

 .首先安装Openssl,再安装OpenSSH,安装先后顺序不可颠倒

     bash-3.2# cd openssl-fips-12.9.8.1801
     bash-3.2# smitty install

 顺序选择Install and Update Software、Install Software，
 INPUT device / directory for software   [.] 输入当前目录.
 SOFTWARE to install [_all_latest]   按F4、然后ESC+7选择列出行
  "ACCEPT new license agreements?"  [yes]
 回车，执行安装
 Command:OK  表示安装完成。
 OpenSSH安装方法同上。

 .安装完成后SSH服务会自动启动，确认：

     bash-3.2# lssrc -s sshd
     Subsystem Group PID Status
     sshd ssh  active

 .启动和停止服务：

     bash-3.2# stopsrc -s sshd
     - The sshd Subsystem was requested to stop.
     bash-3.2# lssrc -s sshd
     Subsystem         Group            PID          Status
      sshd             ssh                           inoperative

     bash-3.2# startsrc -s sshd
     - The sshd Subsystem has been started. Subsystem PID is .
     bash-3.2# lssrc -s sshd
     Subsystem         Group            PID          Status
      sshd             ssh                   active
