Working With Samba

smbmap

• -h - IP address or host to enumerate
• -u - username to use during enumeration (attempts to use the NULL session if not supplied)
• -p - password or NTLM hash to use during enumeration
• -d - domain (or workgroup) to use during enumeration
• -s - share to enumerate (defaults to C$ if not supplied)
• -x - attempt to execute the supplied command (!!!) on the server (if the user you’re connecting as has permission to do so)
• --download/--upload - download or upload a file to specified share

smbclient

smbclient //$IP/$SHARE -U $USER -p $PORT

• -I - IP address to connect to
• -U - username to use for the connection
• -P - password to use for the connection
• -N - attempt to connect without a password
• -W - domain (or workgroup) to use for the connection
• -p - connect to a non-standard port
• -c - attempt to execute the supplied command (!!!) on the server (if the user you’re connecting as has permission to do so)

The -p directive is only necessary if working over a non-standard port (e.g., not 445).

If -U is not included, smbclient will use your current (local) username, so probably best to fill something else in. If a password needs to be sent, specify the user as ${USER}%${PASSWORD}.

The interface is reminiscent of old-school FTP clients.

smbget

smbget smb://$IP/$SHARE/$FILE -U $USER

Download $FILE from $SHARE at $IP.

Note that the semantics are annoyingly slightly different from smbclient - no port specification, and the smb: protocol portion of the URI must be included.

Use -R (and omit $FILE) to recursively download an entire directory.

net share

Use net share on Windows to list all current shares (including some that are just control processes).
