SMB Server: Support for OPTIONS method

[User65k]

Hi,
when I try to access the SMBServer from Windows 7, I get:

code 501, message Unsupported method ('OPTIONS')
"OPTIONS / HTTP/1.1" 501 -

I used this code for the Server:

from impacket import smbserver

class SMBHandler(smbserver.SimpleSMBServer):
    def stop(self):
        #self._SimpleSMBServer__server.socket.close()
        #self._SimpleSMBServer__server.server_close()
        pass

smb = SMBHandler(listenAddress = args.ip, listenPort=args.smb)
smb.addShare("SHARE", args.folder, "")
smb.setSMB2Support(True)

t = Thread(target=smb.start, args=())
t.daemon = True
t.start()

I also tried without SMB2 support. Gives me the same Error. So I guess OPTIONS would be nice for Windows? 😃

WebDAV FTW!

So SMB can't work without a WebDAV Server (on port 80)?

If a SMB connection fails and the WebClient service is running then Windows will attempt to access the same share over WebDAV. For instance, that is how \live.sysinternals.com\tools\ works

Ok, I guess that makes sense.
But what's wrong with the SMB Share then? It works fine with nemo

Hey folks:

Ok.. I need some clarifications here.

1. OPTIONS is a HTTP method. It has nothing to do with SMB. If you launch smbrelayx.py (or ntlmrelayx.py) it will launch a Web Server so you can relay credentials that land there, but in a pure SMB Server (like the example you wrote @User65k) there's not HTTP Server listening.
2. If OPTIONS is needed for a relay scenario, let me know and I'll add it to the HTTPRelayServer, but I'm not sure this is what we're talking about here.

Yes, sorry I got confused. I had a HTTP Server log into the same log as the SMB Server.
So the missing OPTIONS are not relevant and my bad.

However, the small SMB Server I wrote does not work with Windows 7.
The same Server works well with Nemo (File Explorer) and the impacket smb tooling.

The same goes for python smbserver.py SHARE ~/Downloads

I just took a look in Wireshark. My Win never even tries SMB but directly goes to port 80. So I guess my Windows Box is wired and you can close this 😕
