【问题描述】:
我正在尝试从使用 Popen 直接运行 ssh 命令迁移到使用 Paramiko,因为我的代码正在迁移到 ssh 命令不可用的环境。
命令的当前调用传递了一个参数,然后由远程服务器使用。换句话说:
process = subprocess.Popen(['ssh', '-T', '-i<path to PEM file>', 'user@host', 'parameter'])
而远程服务器上的authorised_keys 有:
command="/home/user/run_this_script.sh $SSH_ORIGINAL_COMMAND", ssh-rsa AAAA...
所以我编写了以下代码来尝试模拟这种行为:
def ssh(host, user, key, timeout):
""" Connect to the defined SSH host. """
# Start by converting the (private) key into a RSAKey object. Use
# StringIO to fake a file ...
keyfile = io.StringIO(key)
ssh_key = paramiko.RSAKey.from_private_key(keyfile)
host_key = paramiko.RSAKey(data=base64.b64decode(HOST_KEYS[host]))
client = paramiko.SSHClient()
client.get_host_keys().add(host, "ssh-rsa", host_key)
print("Connecting to %s" % host)
client.connect(host, username=user, pkey=ssh_key, allow_agent=False, look_for_keys=False)
channel = client.invoke_shell()
... code here to receive the data back from the remote host. Removed for relevancy.
client.close()
为了将参数传递给远程主机以便将其用作$SSH_ORIGINAL_COMMAND,我需要进行哪些更改?
