How can I use impacket to test whether a Windows share is accessible?

[CaledoniaProject]

I'd like to know how can I check if a share is writable.

In smbcilent.py I can tell if a share is accessible by checking the exceptions in smbClient.login method, aka https://github.com/fortra/impacket/blob/master/examples/smbclient.py#L98

How can I check if a share is writable?

@CaledoniaProject Here is what you want: https://github.com/Porchetta-Industries/CrackMapExec/blob/master/cme/protocols/smb.py#L716

Try to create and delete a directory to check permissions.
