python sftp&ftp&ssh2

ftp使用内置模块from ftplib import FTP

# ftp settings
ftp_server   = "192.168.0.1"
ftp_port     = "21"
ftp_user     = "user"
ftp_password = "pwd"
def ftp_stor_files(file_zip):
    cmd_stor = "STOR %s" %(os.path.split(file_zip)[1])
    print(cmd_stor)
    ftp = FTP(ftp_server, ftp_user, ftp_password)
    ftp.getwelcome()
    ftp.storbinary(cmd_stor, open(file_zip, "rb"), 1024)
    ftp.close()
    #ftp.quit()

sftp使用import paramiko
paramiko SSH2 protocol for python    协议：LGPL V2.1

上述包依赖：
Python Cryptography Toolkit (pycrypto)
pycrypto安装时需要Visual2003的编译环境

pycrypto安装包，已编译版本：http://www.voidspace.org.uk/python/modules.shtml#pycrypto(或者直接把Crypto解码到Python25\Lib\site-packages文件夹)

详细使用说明参考：安装目录site-packages下的paramiko-1.7.7.1\demos

# ftp settings
ftp_server   = "192.168.0.1"
ftp_port     = 22
ftp_user     = "user"
ftp_password = "pwd"
def sftp_stor_files(file_zip, destFile):
    t = paramiko.Transport((ftp_server, ftp_port))
    t.connect(username=ftp_user, password=ftp_password, hostkey=None)
    sftp = paramiko.SFTPClient.from_transport(t)
    
    # dirlist on remote host
    dirlist = sftp.listdir('.')
    print "Dirlist:", dirlist
    
    sftp.put(file_zip, destFile)

    t.close()

通过ssh2执行shell脚本

def ssh2_exec_command(command):
    print "ssh2 execute command: %s" %(command)
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(ftp_server, username=ftp_user, password=ftp_password)
    stdin, stdout, stderr = ssh.exec_command(command)
    stdin.close()
    for line in stdout.read().splitlines():
        print line
    for line in stderr.read().splitlines():
        print "command error ---%s" %(line)

通过ssh2执行交互式shell脚本

def ssh2_exec_interactive_command():
    print "ssh2 execute interactive command"
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(ftp_server, username=ftp_user, password=ftp_password)
    
    while True:
        cmd = raw_input("Please Input Command to run in server %s : " %(ftp_server))
        if cmd == "":
            break
        channel = ssh.get_transport().open_session()
        print "running '%s'" % cmd
        channel.exec_command(cmd)
        print "exit status: %s" % channel.recv_exit_status()
        print "exit status: %s" % channel.recv(10000)
    
    ssh.close()
