 1 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
 2 §6.4 使用Public Key (OpenSSH) 不用密码登陆.
 3 步骤如下:
 4 l         创建key
 5 1.           $ mkdir -p ~/.ssh                        If it doesn\'t already exist
 6 2.           $ chmod 700 ~/.ssh
 7 3.           $ cd ~/.ssh
 8 $ ssh-keygen -t dsa
 9 l         拷贝key到服务器端
10 $ scp -p id_dsa.pub remoteuser@remotehost:
11 Password: ********
12 l         登陆到服务器端安装公钥
13 $ ssh -l remoteuser remotehost
14 Password: ********
15  
16 remotehost$ mkdir -p ~/.ssh                        If it doesn\'t already exist
17 remotehost$ chmod 700 ~/.ssh
18 remotehost$ cat id_dsa.pub >> ~/.ssh/authorized_keys   (Appending)
19 remotehost$ chmod 600 ~/.ssh/authorized_keys
20 remotehost$ mv id_dsa.pub ~/.ssh        可选步骤,该文件甚至可以删除掉
21 remotehost$ logout
22 l         用public-key登陆
23 $ ssh -l remoteuser remotehost
24 Enter passphrase for key \'/home/smith/.ssh/id_dsa\': ********
25  
26 公钥一般存放在~/.ssh/authorized_keys, 老的OpenSSH版本可能存放在~/.ssh/authorized_keys2.
27  
28 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
29  
30 如果以上不步骤不能实现不输密码登陆,请检查:
31 /etc/ssh/sshd_config:
32 PubkeyAuthentication yes           If no, change it and restart sshd
33 可以用ssh –v来显示详细的登陆过程.
34  
35 SSH-2 key文件格式:
36 SSH的两种主要实现方式: OpenSSH and SSH Secure Shell ("SSH2")
37 OpenSSH 的如下:
38 ssh-dss A9AAB3NzaC1iGMqHpSCEliaouBun8FF9t8p...
39 or:
40 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEA3DIqRox...
41 SSH Secure Shell的如下:
42 ---- BEGIN SSH2 PUBLIC KEY ----
43 AAAAB3NzaC1kc3MAAACBAM4a2KKBE6zhPBgRx4q6Dbjxo5hXNKNWYIGkX/W/k5PqcCH0J6 ...
44 ---- END SSH2 PUBLIC KEY ----
45  
46 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:
47 IdKey private_key_filename
48  

使用Public Key (OpenSSH) 不用密码登陆

 

  1 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。
  2 
  3 1.在IBM官方网站下载Openssl和OPenSSH软件(可下载本文附件)。
  4 2.将下载的软件上传至AIX系统/tmp目录下。
  5 3.解压软件
  6 
  7     bash-3.2# uncompress openssl-fips-12.9.8.1801.tar
  8     bash-3.2# tar xvf openssl-fips-12.9.8.1801.tar 
  9     x openssl-fips-12.9.8.1801
 10     x openssl-fips-12.9.8.1801/openssl.base, 7648256 bytes, 14938 media blocks.
 11     x openssl-fips-12.9.8.1801/openssl.license, 3072 bytes, 6 media blocks.
 12     x openssl-fips-12.9.8.1801/openssl.man.en_US, 2350080 bytes, 4590 media blocks.
 13 
 14     bash-3.2# uncompress OpenSSH_5.8.0.6102.tar.Z
 15     bash-3.2# cd OpenSSH/
 16     bash-3.2# tar xvf OpenSSH_5.8.0.6102.tar 
 17 
 18 
 19 
 20 
 21 OS:AIX 5.3.10
 22 -------------------------------------安装openssl----------------------------------
 23 1.下载openssl
 24 https://www14.software.ibm.com/webapp/iwm/web/reg/download.do?source=aixbp&S_PKG=openssl&lang=en_US#
 25 选择OpenSSL Install images v0.9.8.1802 ( OpenSSL 0.9.8r ) for AIX 5.3 , AIX 6.1 & 7.0
 26  
 27 2.解压缩安装包
 28 [hxl/root]#ls -1 openssl-0.9.8.1802.tar.Z
 29 openssl-0.9.8.1802.tar.Z
 30 [hxl/root]#uncompress openssl-0.9.8.1802.tar.Z
 31  
 32 3.查看tar的内容
 33 [hxl/root]#tar -vtf openssl-0.9.8.1802.tar
 34 drwxr-xr-x   0 0        0 Jun 08 03:33:11 2012 openssl-0.9.8.1802/
 35 -rw-r-----   0 0  6316032 Jun 08 03:32:42 2012 openssl-0.9.8.1802/openssl.base
 36 -rw-r-----   0 0     3072 Jun 08 03:32:52 2012 openssl-0.9.8.1802/openssl.license
 37 -rw-r-----   0 0  2350080 Jun 08 03:33:41 2012 openssl-0.9.8.1802/openssl.man.en_US
 38 [hxl/root]#mkdir opensshl
 39 [hxl/root]#mv openssl-0.9.8.1802.tar ./openssh1
 40 [hxl/root]#tar -xvf openssl-0.9.8.1802.tar
 41  
 42 4.安装
 43 smitty install指定软件的目录,选择安装:openssl.base
 44 ACCEPT new license agreements? 选择YES
 45 
 46 ---------------------------安装openssh-----------------------------------
 47 1.下载openssh,下载地址:http://sourceforge.net/projects/openssh-aix/files/
 48 [hxl/root]#ls -1 openssh_5.2p1_aix53.tar.z
 49 openssh_5.2p1_aix53.tar.z
 50  
 51 2.修改文件名,将后缀小写的z改为大写,然后解压缩
 52 [hxl/root]#mv openssh_5.2p1_aix53.tar.z openssh_5.2p1_aix53.tar.Z
 53 [hxl/root]#uncompress openssh_5.2p1_aix53.tar.Z
 54  
 55 3.查看tar文件内容
 56 [hxl/root]#tar -vtf openssh_5.2p1_aix53.tar
 57 
 58 解压到当前目录
 59 [hxl/root]#mv openssh_5.2p1_aix53.tar ./openssh
 60 [hxl/root]#tar -xvf openssh_5.2p1_aix53.tar
 61  
 62 4.安装
 63 smitty install指定软件软件存放的目录,选择openssh.base
 64 ACCEPT new license agreements? 选择YES
 65  
 66 ------------------------------------运行ssh服务--------------------------
 67 5.运行ssh服务
 68 默认安装好后系统自动启用ssh服务：
 69 [hxl/root]#lssrc -a | grep ssh
 70  sshd             ssh              708860       active
 71  
 72 启动sshd服务
 73 [hxl/root]#startsrc -s sshd
 74  
 75 停止sshd服务
 76 [hxl/root]#stopsrc -s sshd
 77  
 78 这样就可以通过putty或则ssh登陆了
 79 
 80 4.首先安装Openssl,再安装OpenSSH,安装先后顺序不可颠倒
 81 
 82     bash-3.2# cd openssl-fips-12.9.8.1801
 83     bash-3.2# smitty install
 84 
 85 顺序选择Install and Update Software、Install Software，
 86 INPUT device / directory for software   [.] 输入当前目录.
 87 SOFTWARE to install [_all_latest]   按F4、然后ESC+7选择列出行
 88  "ACCEPT new license agreements?"  [yes] 
 89 回车，执行安装
 90 Command:OK  表示安装完成。
 91 OpenSSH安装方法同上。
 92 
 93 5.安装完成后SSH服务会自动启动，确认：
 94 
 95     bash-3.2# lssrc -s sshd
 96     Subsystem Group PID Status
 97     sshd ssh 7077986 active
 98 
 99 6.启动和停止服务：
100 
101     bash-3.2# stopsrc -s sshd
102     0513-044 The sshd Subsystem was requested to stop.
103     bash-3.2# lssrc -s sshd
104     Subsystem         Group            PID          Status 
105      sshd             ssh                           inoperative
106 
107     bash-3.2# startsrc -s sshd 
108     0513-059 The sshd Subsystem has been started. Subsystem PID is 19660822.
109     bash-3.2# lssrc -s sshd
110     Subsystem         Group            PID          Status 
111      sshd             ssh              19660822     active
