How to transfer a file from Junos device

[Mike Strube]

I've generated a tarball file of the /var/log directory on a switch in /var/tmp.  Now, I want to transfer it to the machine I'm running PyEZ on.  The only protocol I have available is SSH/SCP -- no FTP or TFTP.  I can't use sshkeys because I'm using the 'root' user on the switch due to file permissions of the logs and of the tarball.  I do have the root password, but can't seem to find a way to pass it.

Hi Mike, 

You can use the SCP utility.  This creates a SCPClient object.

http://junos-pyez.readthedocs.org/en/1.1.2/jnpr.junos.utils.html#module-jnpr.junos.utils.scp

from jnpr.junos.utils.scp import SCP
with SCP(dev) as scp:
    scp.get('/cf/var/tmp/gksdchk.log', './gksdchk.log')

That works, but with the following warning:

No handlers could be found for logger "paramiko.transport"

Also, the examples indicate an additional parameter, progress=_scp_progress, but if I include it python complains about it not being defined...  It would be nice to get a progress indication...

Hi Mike,

I'll fix/add both of these to the SCP util.

In the mean time, I'll unicast you a script that works around both.

Thanks,
