问题 I'm calling the Paramiko sftp_client.put(locapath,remotepath) method This is throwing the [Errno 2] File not found error below. 01/07/2020 01:12:03 PM - ERROR - [Errno 2] File not found Traceback (most recent call last): File "file_transfer\TransferFiles.py", line 123, in main File "paramiko\sftp_client.py", line 727, in put File "paramiko\sftp_client.py", line 689, in putfo File "paramiko\sftp_client.py", line 460, in stat File "paramiko\sftp_client.py", line 780, in _request File "paramiko

Setting timelimit for sftp.get() of Paramiko module

阅读更多关于 Setting timelimit for sftp.get() of Paramiko module

问题 I am using Paramiko's SFTP client to download a file from remote server to a client(i.e. get operation) The file to be transferred is a bit huge ~1GB. So I would like the get operation to timeout if the time is more than 10s. But setting the timeout value for connect doesn't work, It appears to be the timeout for just creating the SSH connection and not the timeout for the whole ssh connection. ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect

问题 I am trying to remote read a netcdf file. I used paramiko package to read my file, like this: import paramiko from netCDF4 import Dataset client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) client.connect(hostname=’hostname’, username=’usrname’, password=’mypassword’) sftp_client = client.open_sftp() ncfile = sftp_client.open('mynetCDFfile') b_ncfile = ncfile.read() # **** nc = Dataset('test.nc', memory=b_ncfile) But the run speed of ncfile.read() is

Embedding public key as string in Paramiko Application

阅读更多关于 Embedding public key as string in Paramiko Application

问题 I'm trying to create a single file executable in python and using paramiko for my SSH. I need to eliminate external files such as public key files and try to go for embedded strings. I tried this solution but it's not working for me.. How do I accomplish this? Thanks. 回答1: The solution you mentioned: key = paramiko.RSAKey(data=base64.b64decode('AAblablabla...')) works fine however it may be inconvenient to store the key in base64 format. The following code shows how to use the key stored in

PySFTP/Paramiko exceptions leaking into stderr

问题 I am trying to catch paramiko exceptions but they are still written to stderr. Is there a way to stop writing there? EDIT: It happens even before paramiko gets involved: import pysftp try: pysftp.Connection(host="localhost") except Exception as e: print(e) Results in: Example with proper SFTP params: UPDATE: $ pipenv graph ... pysftp==0.2.9 - paramiko [required: >=1.17, installed: 2.6.0] ... $ pipenv run python Python 3.7.3 (default, Jul 19 2019, 11:21:39) [Clang 11.0.0 (clang-1100.0.28.3)]

问题 How can I execute a command on a remote server in Python and pipe the stdout to a local command? To do ssh host 'echo test' | cat in Python, I have tried import paramiko import subprocess ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('host', username='user') ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command('echo test') proc = subprocess.Popen(['cat'], stdin=ssh_stdout) outs, errs = proc.communicate() print(outs) but I get the exception

Can I get the exit code of a command executed in a subshell via ssh?

阅读更多关于 Can I get the exit code of a command executed in a subshell via ssh?

问题 I'm trying to use Paramiko to write a deployment script, and I'm having trouble with exit codes from the commands I run. I'm using code similar to that in this answer, but it's a little more complicated. Basically, from our dev boxes we have to go through a jump server, and from there to a series of production machines. Once there we have to switch to a system user (sudo su - systemuser) and then we can run commands. The problem is that as I understand it I have 3 subshells - the ssh session,
