The lib will read stderr on some occasions, passing it as argument to raised SCPException
s, but otherwise the error output is not read. In fact, having the scp command print out verbose output could fill the receive buffer and freeze paramiko.
I'm trying to find a way for paramiko to log the stderr it gets, but there doesn't seem to be anything built in.
from scp.py.
So from the docs explaining the paramiko.client.SSHClient
Reads
client = SSHClient()
client.load_system_host_keys()
client.connect('ssh.example.com')
stdin, stdout, stderr = client.exec_command('ls -l')
I'm wondering if to solve this issue is it a simple fix of doing
def put and get
...
- self.channel.exec_command(scp_command +
- self.sanitize(asbytes(remote_path)))
+ stdin, stdout, stderr = self.channel.exec_command(scp_command +
+ self.sanitize(asbytes(remote_path)))
...
If you think that is an appropriate solution then let me know and I can make a pull request!
from scp.py.
This will give you pseudo-files you can read from instead of reading from the channel directly, but I'm no sure how it fixes the problem. PR welcome if you want to take a crack at it.
from scp.py.
@remram44 yeah I see what you are saying. The pseudo files can only be read after the exec_command
finishes which doesn't really give us an up to date stdin.

The pseudo files can only be read after the exec_command finishes
No that is not the case. I'm saying there's no difference doing stderr.read()
over the current channel.recv_stderr()
.
