Ssh-Verbindungsnotiz mit ProxyCommand von ssh_config in Python

Host fumidai_host
    User user_name
    Hostname xx.xx.xx.xx (<= GIP)
    IdentityFile ~/.ssh/hoge.pem


Host app_host
    HostName 192.168.0.1 (<= private ip)
    User user_name
    IdentityFile ~/.ssh/hoge.pem
    ProxyCommand ssh -W %h:%p fumidai_host

import os
import paramiko


#Lookup SSH-Konfigurationsdatei
config_file = os.path.join(os.getenv('HOME'), '.ssh/config')
ssh_config = paramiko.SSHConfig()
ssh_config.parse(open(config_file, 'r'))
lkup = ssh_config.lookup(hostname)

#Stellen Sie eine Verbindung mit den ProxyCommand-Einstellungen her
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.connect(
    lkup['hostname'],
    username=lkup['user'],
    key_filename=lkup['identityfile'],
    sock=paramiko.ProxyCommand(lkup['proxycommand'])
)


sftp = ssh.open_sftp()        
#Der Rest ist normal
# sftp.put(src, dist)Oder
# sftp.get(src, dist)Oder

sftp.close()
ssh.close()
