在A上執行keygen,轉換后cp到B上,那么在B上ssh A時不需要口令
§6.4 使用Public Key (OpenSSH) 不用密碼登陸.
步驟如下:
l         創建key
1.           $ mkdir -p ~/.ssh                        If it doesn't already exist
2.           $ chmod 700 ~/.ssh
3.           $ cd ~/.ssh
$ ssh-keygen -t dsa
l         拷貝key到服務器端
$ scp -p id_dsa.pub remoteuser@remotehost:
Password: ********
l         登陸到服務器端安裝公鑰
$ ssh -l remoteuser remotehost
Password: ********
 
remotehost$ mkdir -p ~/.ssh                        If it doesn't already exist
remotehost$ chmod 700 ~/.ssh
remotehost$ cat id_dsa.pub >> ~/.ssh/authorized_keys   (Appending)
remotehost$ chmod 600 ~/.ssh/authorized_keys
remotehost$ mv id_dsa.pub ~/.ssh        可選步驟,該文件甚至可以刪除掉
remotehost$ logout
l         用public-key登陸
$ ssh -l remoteuser remotehost
Enter passphrase for key '/home/smith/.ssh/id_dsa': ********
 
公鑰一般存放在~/.ssh/authorized_keys, 老的OpenSSH版本可能存放在~/.ssh/authorized_keys2.
 
Public-key 認證機制比密碼要安全, 因為密碼不在網絡上傳輸. 而且可以是用加密的方式存儲的,如果沒有別人沒有passphrase,拿到密鑰也沒有用.為此一定要設置passphrase
 
如果以上不步驟不能實現不輸密碼登陸,請檢查:
/etc/ssh/sshd_config:
PubkeyAuthentication yes           If no, change it and restart sshd
可以用ssh –v來顯示詳細的登陸過程.
 
SSH-2 key文件格式:
SSH的兩種主要實現方式: 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的安裝方式也不同,目錄在~/.ssh2 要在, ~/.ssh2/authorization中用如下方式提及: Key public_key_filename. 私鑰也需要在~/.ssh2/identification用如下方式引用:
IdKey private_key_filename
 

 

AIX6.1默認是沒有安裝SSH服務的，要使用SSH連接AIX服務器，必須手動安裝OpenSSH軟件。

1.在IBM官方網站下載Openssl和OPenSSH軟件(可下載本文附件)。
2.將下載的軟件上傳至AIX系統/tmp目錄下。
3.解壓軟件

    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, 7648256 bytes, 14938 media blocks.
    x openssl-fips-12.9.8.1801/openssl.license, 3072 bytes, 6 media blocks.
    x openssl-fips-12.9.8.1801/openssl.man.en_US, 2350080 bytes, 4590 media blocks.

    bash-3.2# uncompress OpenSSH_5.8.0.6102.tar.Z
    bash-3.2# cd OpenSSH/
    bash-3.2# tar xvf OpenSSH_5.8.0.6102.tar 




OS:AIX 5.3.10
-------------------------------------安裝openssl----------------------------------
1.下載openssl
https://www14.software.ibm.com/webapp/iwm/web/reg/download.do?source=aixbp&S_PKG=openssl&lang=en_US#
選擇OpenSSL Install images v0.9.8.1802 ( OpenSSL 0.9.8r ) for AIX 5.3 , AIX 6.1 & 7.0
 
2.解壓縮安裝包
[hxl/root]#ls -1 openssl-0.9.8.1802.tar.Z
openssl-0.9.8.1802.tar.Z
[hxl/root]#uncompress openssl-0.9.8.1802.tar.Z
 
3.查看tar的內容
[hxl/root]#tar -vtf openssl-0.9.8.1802.tar
drwxr-xr-x   0 0        0 Jun 08 03:33:11 2012 openssl-0.9.8.1802/
-rw-r-----   0 0  6316032 Jun 08 03:32:42 2012 openssl-0.9.8.1802/openssl.base
-rw-r-----   0 0     3072 Jun 08 03:32:52 2012 openssl-0.9.8.1802/openssl.license
-rw-r-----   0 0  2350080 Jun 08 03:33:41 2012 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
 
4.安裝
smitty install指定軟件的目錄,選擇安裝:openssl.base
ACCEPT new license agreements? 選擇YES

---------------------------安裝openssh-----------------------------------
1.下載openssh,下載地址:http://sourceforge.net/projects/openssh-aix/files/
[hxl/root]#ls -1 openssh_5.2p1_aix53.tar.z
openssh_5.2p1_aix53.tar.z
 
2.修改文件名,將后綴小寫的z改為大寫,然后解壓縮
[hxl/root]#mv openssh_5.2p1_aix53.tar.z openssh_5.2p1_aix53.tar.Z
[hxl/root]#uncompress openssh_5.2p1_aix53.tar.Z
 
3.查看tar文件內容
[hxl/root]#tar -vtf openssh_5.2p1_aix53.tar

解壓到當前目錄
[hxl/root]#mv openssh_5.2p1_aix53.tar ./openssh
[hxl/root]#tar -xvf openssh_5.2p1_aix53.tar
 
4.安裝
smitty install指定軟件軟件存放的目錄,選擇openssh.base
ACCEPT new license agreements? 選擇YES
 
------------------------------------運行ssh服務--------------------------
5.運行ssh服務
默認安裝好后系統自動啟用ssh服務：
[hxl/root]#lssrc -a | grep ssh
 sshd             ssh              708860       active
 
啟動sshd服務
[hxl/root]#startsrc -s sshd
 
停止sshd服務
[hxl/root]#stopsrc -s sshd
 
這樣就可以通過putty或則ssh登陸了

4.首先安裝Openssl,再安裝OpenSSH,安裝先后順序不可顛倒

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

順序選擇Install and Update Software、Install Software，
INPUT device / directory for software   [.] 輸入當前目錄.
SOFTWARE to install [_all_latest]   按F4、然后ESC+7選擇列出行
 "ACCEPT new license agreements?"  [yes] 
回車，執行安裝
Command:OK  表示安裝完成。
OpenSSH安裝方法同上。

5.安裝完成后SSH服務會自動啟動，確認：

    bash-3.2# lssrc -s sshd
    Subsystem Group PID Status
    sshd ssh 7077986 active

6.啟動和停止服務：

    bash-3.2# stopsrc -s sshd
    0513-044 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 
    0513-059 The sshd Subsystem has been started. Subsystem PID is 19660822.
    bash-3.2# lssrc -s sshd
    Subsystem         Group            PID          Status 
     sshd             ssh              19660822     active
