How can you get the SSH return code using Paramiko?

by

A much easier example that doesn’t involve invoking the “lower level” channel class directly (i.e. – NOT using the client.get_transport().open_session() command): import paramiko client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) client.connect(‘blahblah.com’) stdin, stdout, stderr = client.exec_command(“uptime”) print stdout.channel.recv_exit_status() # status is 0 stdin, stdout, stderr = client.exec_command(“oauwhduawhd”) print stdout.channel.recv_exit_status() # status is 127

How to check if Paramiko successfully uploaded a file to an SFTP server?

With the SFTP, running over an encrypted SSH session, there’s no chance the file contents could get corrupted while transferring. So unless it gets corrupted when reading the local file or writing the remote file, you can be pretty sure that the file was uploaded correctly, if the .put does not throw any error. try: … Read more

SSH key generated by ssh-keygen is not recognized by Paramiko: “not a valid RSA private key file”

For OpenSSH 7.8 up, you have to trick it. Run ssh-keygen -p [-f file] -m pem to purportedly change passphrase, but reuse the old one. Use -P oldpw -N newpw if you want to avoid the prompts, as in a script, but be careful of making your passphrase visible to other users. As a side … Read more

How to download only the latest file from SFTP server with Paramiko?

Use the SFTPClient.listdir_attr instead of the SFTPClient.listdir to get listing with attributes (including the file timestamp). Then, find a file entry with the greatest .st_mtime attribute. The code would be like: latest = 0 latestfile = None for fileattr in sftp.listdir_attr(): if fileattr.filename.startswith(‘Temat’) and fileattr.st_mtime > latest: latest = fileattr.st_mtime latestfile = fileattr.filename if latestfile … Read more

How to list all the folders and files in the directory after connecting through SFTP in Python

by

The SFTPClient.listdir returns everything, files and folders. Were there folders, to tell them from the files, use SFTPClient.listdir_attr instead. It returns a collection of SFTPAttributes. from stat import S_ISDIR, S_ISREG sftp = ssh.open_sftp() for entry in sftp.listdir_attr(remotedir): mode = entry.st_mode if S_ISDIR(mode): print(entry.filename + ” is folder”) elif S_ISREG(mode): print(entry.filename + ” is file”) The … Read more
