This library implements the SMBv2 and SMBv3 protocol based on the [MS-SMB2](https://msdn.microsoft.com/en-us/library/cc246482.aspx) document. ## Features * Negotiation of the SMB 2.0.2 protocol to SMB 3.1.1 (Windows 10/Server 2016) * Authentication with both NTLM and Kerberos * Message signing * Message encryption (SMB 3.x.x+) * Connect to a Tree/Share * Opening of files, pipes and directories * Set create contexts when opening files * Read and writing of files and pipes * Sending IOCTL commands * Sending of multiple messages in one packet (compounding) * Experimental support for both standalone and DFS server shares This is definitely not feature complete as SMB is quite a complex protocol, see backlog for features that would be nice to have in this library. ## Requirements * Python 3.7+ * For Kerberos auth on Linux * [python-gssapi](https://github.com/pythongssapi/python-gssapi) * [pykrb5](https://github.com/jborean93/pykrb5) To use Kerberos authentication on Linux, further dependencies are required, to install these dependencies run ```bash # for Debian/Ubuntu/etc: sudo apt-get install gcc python-dev libkrb5-dev pip install smbprotocol[kerberos] # for RHEL/CentOS/etc: sudo yum install gcc python-devel krb5-devel krb5-workstation python-devel pip install smbprotocol[kerberos] ``` Kerberos auth with Windows should just work out of the box with the `pyspnego` library but on Linux, the `python-gssapi` library must be installed and `smbprotocol` requires a particular GSSAPI extension to be available to work. This extension should be installed on the majority of MIT or Heimdal Kerberos installs but that is not a guarantee. To verify that Kerberos is available on Linux you can run the following check in a Python console: ```python try: from gssapi.raw import inquire_sec_context_by_oid print("python-gssapi extension is available") except ImportError as exc: print("python-gssapi extension is not available: %s" % str(exc)) ``` If it isn't available, then either a newer version of the system's gssapi implementation needs to be setup and python-gssapi compiled against that newer version. In the absence of this extension, only NTLM auth is used. ## Installation To install smbprotocol, simply run ```bash pip install smbprotocol # To install with Kerberos support pip install smbprotocol[kerberos] ``` This will download the required packages that are used in this package and get your Python environment ready to go. ## Additional Info One of the first steps as part of the SMB protocol is to negotiate the dialect used and other features that are available. Currently smbprotocol supports the following dialects; * `2.0.0`: Added with Server 2008/Windows Vista * `2.1.0`: Added with Server 2008 R2/Windows 7 * `3.0.0`: Added with Server 2012/Windows 8 * `3.0.2`: Added with Server 2012 R2/Windows 8.1 * `3.1.1`: Added with Server 2016/Windows10 Each dialect adds in more features to the protocol where some are minor but some are major. One major changes is in Dialect 3.x where it added message encryption. Message encryption is set to True by default and needs to be overridden when creating a Session object for the older dialects. By default, the negotiation process will use the latest dialect that is supported by the server but this can be overridden if required. When this is done by the following code ```python import uuid from smbprotocol.connection import Connection, Dialects connection = Connection(uuid.uuid4(), "server", 445) connection.connect(Dialects.SMB_3_0_2) ``` While you shouldn't want to downgrade to an earlier version, this does allow you to set a minimum dialect version if required. ## Examples There are 2 different APIs you can use with this library. * `smbprotocol`: Low level interface that can do whatever you want but quite verbose * `smbclient`: Higher level interface that implements the builtin `os` and `os.path` file system functions but for SMB support The `examples` folder contains some examples of both the high and low level interface but for everyday user's it is recommended to use `smbclient` as it is a lot simpler. ### smbclient Interface The higher level interface `smbclient` is designed to make this library easier for people to use for simple and common use cases. It is designed to replicate the builtin `os` and `os.path` filesystem functions like `os.open()`, `os.stat()`, and `os.path.exists()`. It is also designed to handle connections to a DFS target unlike `smbprotocol`. A connection made by `smbclient` is kept in a pool and re-used for future requests to the same server until the Python process exists. This makes authentication simple and only required for the first call to the server. Any DFS referrals are also cached in that Python process. This optimises any future requests to that same DFS namespace. The functions in `smbclient` have a global config object that can be used to set any connection defaults to use for any future connections. It can also be used to specify any domain based DFS settings for more advanced setups. It is recommended to use `ClientConfig()` to set any global credentials like so: ```python import smbclient smbclient.ClientConfig(username='user', password='password') ``` The `ClientConfig` is a singleton and any future instanciations of that object will just update the keys being set. You can set the following keys on the `ClientConfig`: * `client_guid`: The client GUID to identify the client to the server on a new connection * `username`: The default username to use when creating a new SMB session if explicit credentials weren't set * `password`: The default password to use for authentication * `domain_controller`: The domain controller hostname. This is useful for environments with DFS servers as it is used to identify the DFS domain information automatically * `skip_dfs`: Whether to skip doing any DFS resolution, useful if there is a bug or you don't want to waste any roundtrip requesting referrals * `auth_protocol`: The authentication protocol to use; `negotiate` (default), `kerberos`, or `ntlm` * `require_secure_negotiate`: Control whether the client validates the negotiation info when connecting to a share (default: `True`). * More information can be found on [SMB3 Secure Dialect Negotiation](https://docs.microsoft.com/en-us/archive/blogs/openspecification/smb3-secure-dialect-negotiation) As well as setting the default credentials on the `ClientConfig` you can also specify the credentials and other connection parameters on each `smbclient` function or when registering a new server. These functions accept the following kwargs: * `username`: The username used to connect to the share * `password`: The password used to connect to the share * `port`: Override the default port (`445`) to connect to * `encrypt`: Whether to force encryption on the connection, requires SMBv3 or newer on the remote server (default: `False`) * `connection_timeout`: Override the connection timeout in seconds (default: `60`) If using Kerberos authentication and a Kerberos ticket has already set by `kinit` then `smbclient` will automatically use those credentials without having to be explicitly set. If no ticket has been retrieved or you wish to use different credentials then set the default credentials on the `ClientConfig` or specify `username` and `password` on the first request to the server. For example I only need to set the credentials on the first request to create the directory and not for the subsequent file creation in that dir. ```python import smbclient # Optional - specify the default credentials to use on the global config object smbclient.ClientConfig(username='user', password='pass') # Optional - register the credentials with a server (overrides ClientConfig for that server) smbclient.register_session("server", username="user", password="pass") smbclient.mkdir(r"\\server\share\directory", username="user", password="pass") with smbclient.open_file(r"\\server\share\directory\file.txt", mode="w") as fd: fd.write(u"file contents") ``` If you wish to reset the cache you can either start a new Python process or call `smbclient.reset_connection_cache()` to close all the connections that have been cached by the client. ## Logging This library makes use of the builtin Python logging facilities. Log messages are logged to the `smbprotocol` named logger as well as `smbprotocol.*` where `*` is each python script in the `smbprotocol` directory. These logs are really useful when debugging issues as they give you a more step by step snapshot of what it is doing and what may be going wrong. The debug side will also print out a human readable string of each SMB packet that is sent out from the client so it can get very verbose. ## Testing To this module, you need to install some pre-requisites first. This can be done by running; ```bash pip install -r requirements-test.txt # you can also run tox by installing tox pip install tox ``` From there to run the basic tests run; ```bash py.test -v --pep8 --cov smbprotocol --cov-report term-missing # or with tox 2.7, 2.7, 3.4, 3.5, and 3.6 tox ``` There are extra tests that only run when certain environment variables are set. To run these tests set the following variables; * `SMB_USER`: The username to authenticate with * `SMB_PASSWORD`: The password to authenticate with * `SMB_SERVER`: The IP or hostname of the server to authenticate with * `SMB_PORT`: The port the SMB server is listening on, default is `445` * `SMB_SHARE`: The name of the share to connect to, a share with this name must exist as well as a share with the name`$SMB_SHARE-encrypted` must also exist that forces encryption From here running `tox` or `py.test` with these environment variables set will activate the integration tests. This requires either Windows 10 or Server 2016 as they support Dialect 3.1.1 which is required by the tests. If you don't have access to a Windows host, you can use Docker to setup a Samba container and use that as part of the tests. To do so run the following bash commands; ```bash source ./build_helpers/lib.sh lib::setup::smb_server ``` This command will also set the required `SMB_*` env vars used in testing. ## Backlog Here is a list of features that I would like to incorporate, PRs are welcome if you want to implement them yourself; * Multiple channel support to speed up large data transfers * Lots and lots more... %package -n python3-smbprotocol Summary: Interact with a server using the SMB 2/3 Protocol Provides: python-smbprotocol BuildRequires: python3-devel BuildRequires: python3-setuptools BuildRequires: python3-pip %description -n python3-smbprotocol # smbprotocol SMBv2 and v3 Client for Python.

This can be done by running; ```bash pip install -r requirements-test.txt # you can also run tox by installing tox pip install tox ``` From there to run the basic tests run; ```bash py.test -v --pep8 --cov smbprotocol --cov-report term-missing # or with tox 2.7, 2.7, 3.4, 3.5, and 3.6 tox ``` There are extra tests that only run when certain environment variables are set. To run these tests set the following variables; * `SMB_USER`: The username to authenticate with * `SMB_PASSWORD`: The password to authenticate with * `SMB_SERVER`: The IP or hostname of the server to authenticate with * `SMB_PORT`: The port the SMB server is listening on, default is `445` * `SMB_SHARE`: The name of the share to connect to, a share with this name must exist as well as a share with the name`$SMB_SHARE-encrypted` must also exist that forces encryption From here running `tox` or `py.test` with these environment variables set will activate the integration tests. This requires either Windows 10 or Server 2016 as they support Dialect 3.1.1 which is required by the tests. If you don't have access to a Windows host, you can use Docker to setup a Samba container and use that as part of the tests. To do so run the following bash commands; ```bash source ./build_helpers/lib.sh lib::setup::smb_server ``` This command will also set the required `SMB_*` env vars used in testing. ## Backlog Here is a list of features that I would like to incorporate, PRs are welcome if you want to implement them yourself; * Multiple channel support to speed up large data transfers * Lots and lots more... %prep %autosetup -n smbprotocol-1.10.1 %build %py3_build %install %py3_install install -d -m755 %{buildroot}/%{_pkgdocdir} if [ -d doc ]; then cp -arf doc %{buildroot}/%{_pkgdocdir}; fi if [ -d docs ]; then cp -arf docs %{buildroot}/%{_pkgdocdir}; fi if [ -d example ]; then cp -arf example %{buildroot}/%{_pkgdocdir}; fi if [ -d examples ]; then cp -arf examples %{buildroot}/%{_pkgdocdir}; fi pushd %{buildroot} if [ -d usr/lib ]; then find usr/lib -type f -printf "/%h/%f\n" >> filelist.lst fi if [ -d usr/lib64 ]; then find usr/lib64 -type f -printf "/%h/%f\n" >> filelist.lst fi if [ -d usr/bin ]; then find usr/bin -type f -printf "/%h/%f\n" >> filelist.lst fi if [ -d usr/sbin ]; then find usr/sbin -type f -printf "/%h/%f\n" >> filelist.lst fi touch doclist.lst if [ -d usr/share/man ]; then find usr/share/man -type f -printf "/%h/%f.gz\n" >> doclist.lst fi popd mv %{buildroot}/filelist.lst . mv %{buildroot}/doclist.lst . %files -n python3-smbprotocol -f filelist.lst %dir %{python3_sitelib}/* %files help -f doclist.lst %{_docdir}/* %changelog * Fri Apr 21 2023 Python_Bot - 1.10.1-1 - Package Spec generated
