示例1：带账号的登录执行 password\_auth.py

#!/usr/bin/python
    
    """Example script for authentication with password"""
    
    from __future__ import print_function
    
    import argparse
    import socket
    import os
    import pwd
    import sys
    
    from ssh2.session import Session
    
    
    USERNAME = pwd.getpwuid(os.geteuid()).pw_name
    
    parser = argparse.ArgumentParser()
    
    parser.add_argument('password', help="User password")
    parser.add_argument('cmd', help="Command to run")
    parser.add_argument('--host', dest='host',
                        default='localhost',
                        help='Host to connect to')
    parser.add_argument('--port', dest='port', default=22, help="Port to connect on", type=int)
    parser.add_argument('-u', dest='user', default=USERNAME, help="User name to authenticate as")
    
    
    def main():
        args = parser.parse_args()
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sock.connect((args.host, args.port))
        s = Session()
        s.handshake(sock)
        s.userauth_password(args.user, args.password)
        chan = s.open_session()
        chan.execute(args.cmd)
        size, data = chan.read()
        while size > 0:
            print(data)
            size, data = chan.read()
    
    
    if __name__ == "__main__":
        main()

示例2

执行远程命令

读取远程文件写入本地文件

from socket import *
    from ssh2.session import Session
    from ssh2.sftp import LIBSSH2_FXF_READ, LIBSSH2_SFTP_S_IRUSR
    
    sock = socket(AF_INET,SOCK_STREAM,0)
    sock.connect(("121.37.18.151",22))
    
    
    session = Session()
    session.handshake(sock)
    
    print(session.userauth_list('myname'))
    session.userauth_password('myname','mypassword')
    
    channel = session.open_session()
    channel.execute('ls -l')
    size,data = channel.read()
    while size > 0:
        print(data)
        size,data = channel.read()
    
    
    sftp = session.sftp_init()
    with sftp.open("1.txt",LIBSSH2_FXF_READ,LIBSSH2_SFTP_S_IRUSR) as remote_fh, open("1.txt",'wb') as local_fh:
        for size,data in remote_fh:
            local_fh.write(data)
