npm install ssh2

 ssh2文件下载：

//前台命令下发
app.get('/test/fileDownload', function (req, res) {
    var downloadPath = req.query.downloadPath;
    console.log(downloadPath);

    var conn = new Client();
    conn.on('ready', function() {
        console.log('Client :: ready');
        conn.sftp(function(err, sftp) {
            if (err) throw err;
            //sftp.fastPut('/home/admin/foo/expdat.log','/home/book/foo/expdat.log', function(err, list) {
            sftp.fastGet('/home/book/foo/expdat.log','/home/admin/foo/expdat.log' ,function(err, result) {
                if (err) throw err;
                //console.log('----------GET  BEGIN!-------------');
                res.download(downloadPath);
                //console.log('----------GET  END!-------------');
                conn.end();
            });
        });
    }).connect({

        port: 22,
        username: 'admin',
        password: 'admin'

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
1.           $ mkdir -p ~/.ssh                        If it doesn't already exist
2.           $ chmod 700 ~/.ssh
3.           $ 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 700 ~/.ssh
remotehost$ cat id_dsa.pub >> ~/.ssh/authorized_keys   (Appending)
remotehost$ chmod 600 ~/.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-2 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
 

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。

1.在IBM官方网站下载Openssl和OPenSSH软件(可下载本文附件)。
2.将下载的软件上传至AIX系统/tmp目录下。
3.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, 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
-------------------------------------安装openssl----------------------------------
1.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 v0.9.8.1802 ( OpenSSL 0.9.8r ) for AIX 5.3 , AIX 6.1 & 7.0
 
2.解压缩安装包
[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的内容
[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-----------------------------------
1.下载openssh,下载地址: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,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
 
3.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
 
4.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--------------------------
5.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              708860       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

4.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。

5.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 7077986 active

6.启动和停止服务：

    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
