For obfs4proxy, I could pass arguments to enable logging:

[ronlam@localhost pluggabletransportadapter]$ obfs4proxy --help
Usage of obfs4proxy:
  -enableLogging
        Log to TOR_PT_STATE_LOCATION/obfs4proxy.log
  -logLevel string
        Log level (ERROR/WARN/INFO/DEBUG) (default "ERROR")
  -obfs4-distBias
        Enable obfs4 using ScrambleSuit style table generation
  -unsafeLogging
        Disable the address scrubber
  -version
        Print version and exit

But using the script to pass arguments will cause error:

standalone_server_config.ini :

[ronlam@localhost pluggabletransportadapter]$ cat standalone_server_config.ini
[common]
exec = /usr/local/bin/obfs4proxy -enableLogging
statedir = /tmp/.pt-state
forward = 127.0.0.1:7000

[transports]
obfs4 = 127.0.0.1:7900

As stated in code, the standalone_server.py use subprocess.Popen(). The script pass whole '/usr/local/bin/obfs4proxy -enableLogging' as string, so the problem occurred.

May this script possible to use something like shlex.split() to split exec string to list before passing to the subprocess.Popen()?

This is running on Windows 10 with Python 3.11.4.

I want to connect with ptadapter and obfs3 to openvpn server the config files are below:

##Client config:
[client]
exec = "D:\MyApp\ptadapter_config\obfs4proxy.exe"
#state = "D:\MyApp\ptadapter_config\state"
tunnels = fn_obfs_4 fn_obfs_3
[fn_obfs_3]
transport = obfs3
listen = 127.0.0.1:3883
upstream = x.x.x.x:10113

##Server Config
[server]
exec = /usr/bin/obfs4proxy -enableLogging
state = ./state
forward = 127.0.0.1:1194
tunnels = server_obfs4 server_obfs3
[server_obfs3]
transport = obfs3
listen = 127.0.0.1:10113

i did use socks proxy on openvpn client also and after i click on connect button the below error occured on client terminal:

Maybe its a bug idk but i have same problem when i tried obfs4 connection btw.
Tanks for your great work.

In the current version, I run the program with
python3 ./standalone.py --server --verbose ./standalone_server_config.ini
with the recent version of obfs4proxy for TorBrowser.
The config file:

[obfs4-options]
iat-mode = 0

(In other words, the config options node-id, private-key, public-key, drbg-seed are left out, like the manual suggests.)

The program does not run, instead it produces error
future: <Future finished exception=PTExecSMethodError("SMETHOD-ERROR obfs4 missing argument 'node-id'",)>

Declaring any options-* in the config file results in ValueError: too many values to unpack (expected 2)

I am following instructions on installing obfs4proxy with openvpn here: https://mosin.ca/index.php/2018/09/05/setting-up-openvpn-with-obfs4proxy/

The startup script includes:
ExecStart=/usr/bin/python3 /etc/openvpn/pluggabletransportadapter/standalone.py --server /etc/openvpn/pluggabletransportadapter/standalone_server_config.ini

However, the git clone directory does not include the scripts 'standalone.py' or 'standalone_server_config.ini'. I have created the server ini file from the example_config.ini, but am stuck without the standalone.py file.

I am also using a redhat fork (like centos) which has python 3.6 installed. The original howto called for python3. Will 3.6 work the same?

I am assuming the files have changed since the howto was published. Can you please advise the current procedure?

This is the "standalone_client_config.ini".

[transports]
# Define transports supported by the PT here. Each supported transport type may
# have several clients with different options. Syntax:
# <config-section> = <transport-name>
# config-section is case-insensitive, and must not be "common" or "default".
obfs4-client1 = obfs4
obfs4-client2 = obfs4
obfs4-client3 = obfs4

We can use single client process manage three-more client instance.
And is there any possible to forward so much more address and port by single server process?
("standalone_server_config.ini")

Can you show an example of CONF_FILE for Windows systems ?? Thanks for you work.

Hi.

Strange error. Works fine when using meek testing on localhost, but bombs out repeatedly (after a few seconds at most) when deploying meek on cloud platform. Have attached stderr output example.

Is this meek_client or wrapper issue?

Thanks
example - worked for a while with meek.zip

Just give me the file

Github not support upload 7z so this is not a zip archive,
download and rename to 7z
ptadapter-3.0.0_windows_x64.zip
ptadapter-3.0.0_linux_x64.zip

Purpose

Pack ptadapter to pyinstaller then later use in other environment

Before pack

• Add these (1) to very first line in main.py
• Search and replace every "from . import something" to "import something"
• Create dependencies list and include them by "--hidden-import" (2)

(1)

# Process PYTHONPATH
import os
import sys
SCRIPT_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(os.path.dirname(SCRIPT_DIR))

# Other code from upstream

(2)

• Search "import" use VSCode from "*.py" under source directory
• Right click and choose Copy all to a new text file
• Delete py file name use regex replace
  .*\.py\n
• Delete line number
  .*:
• Delete comment if green lines appears too much
  #.*\n
• Manual clean rest artifacts, keep each line one include without space or tab
• Delete duplicate lines, sort alphabet
• Delete extra subinclude (If import os, delete os.path etc.)
• Replace import as --hidden-import
• Use multi-line edit convert linebreak to space (merge into same line as command line argument)

Pack

• Install pyinstaller in global python environment
• Run pyinstaller (2) main.py
• Copy all source code to dist folder

Imagine main.exe as main.py, it can't survive without other source files.
