How to scp in Python

Question

What s the most pythonic way to scp a file in Python   The only route I m aware of is   os system  scp   s    s  s      localfile  remotehost  remotefile      which is a hack  and which doesn t work outside Linux-like systems  and which needs help from the Pexpect module to avoid password prompts unless you already have passwordless SSH set up to the remote host   I m aware of Twisted s conch  but I d prefer to avoid implementing scp myself via low-level ssh modules   I m aware of paramiko  a Python module that supports SSH and SFTP  but it doesn t support SCP   Background  I m connecting to a router which doesn t support SFTP but does support SSH SCP  so SFTP isn t an option   EDIT  This is a duplicate of How to copy a file to a remote server in Python using SCP or SSH    However  that question doesn t give an scp-specific answer that deals with keys from within Python   I m hoping for a way to run code kind of like  import scp  client   scp Client host host  user user  keyfile keyfile    or client   scp Client host host  user user  client use system keys     or client   scp Client host host  user user  password password     and then client transfer   etc local filename     etc remote filename

You can use the package subprocess and the command call to use the scp command from the shell   from subprocess import call  cmd    scp user1 host1 files user2 host2 files  call cmd split

Hmmm  perhaps another option would be to use something like sshfs  there an sshfs for Mac too    Once your router is mounted you can just copy the files outright    I m not sure if that works for your particular application but it s a nice solution to keep handy

Have a look at fabric transfer   from fabric import Connection  with Connection host  hostname                    user  admin                    connect kwargs   key filename     home myuser  ssh private key                    as c      c get   foo bar file txt     tmp

If you are on  nix you can use sshpass  sshpass -p password scp -o User username -o StrictHostKeyChecking no src dst  path

I don t think there s any one module that you can easily download to implement scp  however you might find this helpful   http   www ibm com developerworks linux library l-twist4 html

I while ago I put together a python SCP copy script that depends on paramiko  It includes code to handle connections with a private key or SSH key agent with a fallback to password authentication   http   code activestate com recipes 576810-copy-files-over-ssh-using-paramiko

You could also check  out paramiko  There s no scp module  yet   but it fully supports sftp    EDIT  Sorry  missed the line where you mentioned paramiko  The following module is simply an implementation of the scp protocol for paramiko  If you don t want to use paramiko or conch  the only ssh implementations I know of for python   you could rework this to run over a regular ssh session using pipes   scp py for paramiko

if you install putty on win32 you get an pscp  putty scp    so you can use the os system hack on win32 too    and you can use the putty-agent for key-managment     sorry it is only a hack   but you can wrap it in a python class

As of today  the best solution is probably AsyncSSH  https   asyncssh readthedocs io en latest  scp-client  async with asyncssh connect  host tld   as conn      await asyncssh scp  conn   example txt         recurse True

It has been quite a while since this question was asked  and in the meantime  another library that can handle this has cropped up  You can use the copy function included in the Plumbum library   import plumbum r   plumbum machines SshMachine  example net        this will use your ssh config as  ssh  from shell      depending on your config  you might also need additional      params  eg   user  username   keyfile   ssh some key   fro   plumbum local path  some file   to   r path   path to destination    plumbum path utils copy fro  to

Try the Python scp module for Paramiko  It s very easy to use  See the following example   import paramiko from scp import SCPClient  def createSSHClient server  port  user  password       client   paramiko SSHClient       client load system host keys       client set missing host key policy paramiko AutoAddPolicy        client connect server  port  user  password      return client  ssh   createSSHClient server  port  user  password  scp   SCPClient ssh get transport      Then call scp get   or scp put   to do SCP operations    SCPClient code
