phxd

phxd (Python hxd) is a fully functional Hotline pure Python server written with Twisted, originally written by Vertigo (avaraline.net) and later extended with hybrid IRC support by kang. The IRC support allows connecting to phxd using an IRC client and maps several HLX (Hotline) functions, like public chat, private messages and more. A tracker client functionality to register a phxd server instance with a (passwordless, public) Hotline tracker server was then later added.

Dependencies

  • phxd is only compatible with Python 2, and there is no support for Python 3 or any plans to implement it.
  • phxd is Twisted based, and as such requires Twisted to run. This should be the only dependency required to run it on any standard Python 2 version. Twisted can be installed via pip:
pip install twisted

Configuration

Configuration attributes

phxd's configuration is stored in the config.py Python file. The configuration can be altered directly inside the file (advanced users) or via a supplied interactive tool.

The program offers two methods of storing server related data (accounts, news, etc.): "MySQL" and "Text".

  • "MySQL" allows connecting to a mysql database instance with user/pass specified in the config.py file, and will use or create a new config.py "DB_NAME" database to store phxd data. Note that storing phxd data using "MySQL" has not been tested recently.
  • "Text" database will create a few db_*.tx files and directories containing the data generated by running phxd such as accounts data, banlist, news etc.

If the config.py "ENABLE_FILE_LOG" is set to True, phxd will logs its internal events to the "LOG_FILE" path, rotating logfiles every "LOG_MAX_SIZE_MBYTES", keeping a maximum of "MAX_LOG_FILES".

The "SERVER_NAME" and "SERVER_DESCRIPTION" attributes will be used to advertise the server to Hotline tracker servers. By default, the phxd instance will not be listed on any trackers. This can be changed by editing the "TRACKER_LIST" config attribute. Note that this attribute is not configurable via the interactive configurator tool and must be modified directly inside the config.py file. To enable trackers, edit the property so as to create a list of tuples, each composed with a hostname string (it can also be an IP address) and a port integer. The Hotline server default port for advertising servers is 5499, this differs to the port used by clients to list servers. The following configuration will get your server listed on the (currently) most active Hotline trackers running:

TRACKER_LIST=[("tracker.preterhuman.net", 5499),
              ("tracked.agent79.org", 5499),
              ("hotline.duckdns.org", 5499),
              ("tracked.stickytack.com", 5499),
              ("tracked.nailbat.com", 5499),
              ("hotline.ubersoft.org", 5499)]

First time configuration

Before running phxd, you should either edit the config.py file directly with the proper configuration that suits you (pay particular attention to the "DB_TYPE", "SERVER_NAME" and "SERVER_DESCRIPTION" attributes) or alternatively run the configurator.py tool interactively which will prompt you for important configuration options and rewrite the config.py file itself. IMPORTANT NOTE: If you modify the config.py file directly and have selected "DB_TYPE" as "Text" or left that field default (which is "Text"), you must run the configurator tool with no arguments: $ ./configure_phxd.py to generate the text database base files.

  • Interactive configuration The interactive tool provides an easy way to configure phxd's most common configuration options. phxd should be configured before its first launch, by using the "configure_phxd.py" script as follow:
$ ./configure_phxd.py -i

The configurator script will prompt you with several configuration attributes in the following form ATTRIBUTE_NAME=<default value> [Legal value/Legal value]. If you wish to leave a specific attribute as default, press the "Enter" key. If you wish to change a particular attribute, enter the new value and press Enter, as shown in the following example:

$ ./configure_phxd.py -i
Choose a new value for each configuration attribute, and press enter or leave blank to leave the defaults in place.
If selecting 'DB_TYPE=Text' DB_USER, DB_PASS and DB_NAME don't apply.
DB_TYPE=Text [Text/MySQL]	MySQL
DB_USER=root	testuser
DB_PASS=	
DB_NAME=phxd	newservername
...

Once all the questions have been answered, the configurator program will exit, rewrite the config.py file according to the new attribute values given (or leaving all the options "as is" if none were changed), and generate the initial text database files (if a "Text" DB type was chosen).

  • Editing config.py file directly This is recommended for Users with some knowledge of Python, since the config.py file is actually a Python file that gets imported into the program. Attributes can be changed at will, and this method is the only way to register the server on trackers (see previous "Configuration attributes" section). Once the attributes have been modified, make sure to run $ ./configure_phxd.pyto generate the appropriate supporting files before running phxd for the first time.

Installation

Running phxd on a traditional operating system

There is no setup.py or other install package supplied with phxd. The program can be launched directly by simply invoking it in Python 2.7: $ python2 phxd

Alternatively, a systemd service file could be created to run phxd on startup. Pay particular attention to the "DB_FILE_*" attributes if you are using a "DB_TYPE" of "Text" as phxd will create those database files by default to a "textdb" subdirectory relative to itself, which could be problematic if the program is moved to a system directory like /usr/sbin. The "DB_FILE_BASEPATH" property can be altered to specify an absolute path instead. The same warning is also true for the "LOG_FILE" attribute, in which the phxd event logs will be stored by default.

Running phxd as a Docker container

This is by far the easiest and most reliable method of installing phxd. A Dockerfile is supplied inside this repository to create a ~60MiB python:2-alpine image that will run phxd as a container, using a docker Volume for "Text" database data and event logfiles. The container can be configured, built and deployed as follow:

  1. Configure config.py as described in the earlier "First time configuration" section.
  2. If you are using a "DB_TYPE" of "Text" or have set "ENABLE_FILE_LOG" to True, you must create a Docker volume where phxd data will be stored as follow:
# docker volume create <volumename>. We'll use "phxdvol" as a <volumename> in this example.
docker volume create phxdvol

NOTE: You can replace the Volume name as you see fit, or use an existing Volume if preferred. 3. Now it is time to build your phxd Docker image. the config.py file will be copied directly into the image:

# This must be ran from inside the "phxd" git repository directory
docker build -t phxd .
  1. Once the Docker image has been built, the phxd container can be ran as follow:
docker run -v phxdvol:/app/textdb -d -p 5500:5500 -p 6667:5500 --restart=unless-stopped phxd:latest
  • The "-v" option specifies which Volume should be mapped into the container and where should it be mounted.
  • The "-d" option tells Docker to detach from this container (i.e. run it in the background as a daemon)
  • The "-p" options tell Docker which ports to listen to on the host OS and where to remap them inside the container.
    • We remap port 5500 which is the default Hotline port to the container port 5500 which phxd listens to
    • We also remap port 6667 to the container as IRC clients will by default use that port and phxd only listens to a single, shared port.
  • The "--restart=unless-stopped" option will tell Docker to restart this container automatically on reboot or after a crash.
  • The last positional argument "phxd:latest" tells Docker to use the latest version of the "phxd" image we built earlier.

Before running the command, make sure all options match your configuration if you are altered the defaults:

  • DO replace the "phxdvol" name with the Volume name you chose earlier.
  • DO replace "textdb" from the "/app/textdb" argument with the "DB_FILE_BASEPATH" attribute from the config.py file if you have modified it.
  • DO adjust the "-p" options to map the "SERVER_PORT" configuration option if you have changed it (it defaults to 5500).
  • DO change the "--restart=unless-stopped" option if you do not want phxd to restart automatically on reboot.

Once you have executed the above docker run command, your container should be running and visible in Docker using docker ps:

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                                            NAMES
78978978989         phxd:latest         "python phxd"       6 days ago          Up 5 days           0.0.0.0:5500->5500/tcp, 0.0.0.0:6667->5500/tcp   some_funny_name

Reconfiguring config.py

Since the config.py file gets copied directly into the phxd Docker image when first built, it cannot be changed easily after the image is built. A solution to this problem is to rebuild the Docker image if changes are made to the config.py file. If you have changed the file, run the following commands to stop, rebuild and restart the phxd container:

  1. Rebuild the container (after having made changes to the config.py file):
# This must be ran from inside the "phxd" git repository directory
docker build -t phxd .
  1. Stop the running phxd running container instance. This would have been necessary anyways as the config file is only read on phxd's startup:
# Use docker stop <container_name>, so following our earlier example we would issue:
docker stop some_funny_name
  1. Restart the phxd container with the latest image we have just built:
# NOTE: edit the following command according to your parameters
docker run -v phxdvol:/app/textdb -d -p 5500:5500 -p 6667:5500 --restart=unless-stopped phxd:latest

Since we are using a Docker Volume to store all of phxd's user data, the server should restart in the same state and with the same logs as the previous instance, which means that it is safe to destroy running containers instances and rebuild the Docker image with changes to the code or config.py and will not result in lost metadata or User data.

Usage

Once running, phxd can be connected to by pointing any Hotline or IRC client at its config.py "SERVER_PORT".

  • Hotline When using a Hotline client, you can connect to the server as "Guest" by using a username of "guest" and no password. Guest access is fairly limited, and this is only useful to test your server. You will need to login as "admin" using a default password of "adminpass" and immediately change the admin password to a pass of your choice, or delete the admin account (after creating another priviledged account of course).
  • IRC When using an IRC client, after connecting to the server you will be greeted with the following message:
12:40 !phxd.server.tld *** Welcome to Hotline
12:40 !phxd.server.tld *** You are NOT logged in
12:40 !phxd.server.tld *** Please send '/msg loginserv login password' to proceed.
12:40 !phxd.server.tld *** If you do not have an account, use '/msg loginserv guest' to proceed.

You must login either as "guest" or as any other User (e.g. "admin") in order to access any functionality of the server. To login simply send a private message to "loginserv" with your username and password. **NOTE:**phxd doesn't support encryption or SASL, your user and password will be sent in cleartext. Make sure to use a unique password for phxd to avoid password reuse with other services. To login as guest, issue the following command: /msg loginserv guest. The server will "force-join" you to the #public channel. This channel actually corresponds to the public chat from the Hotline server. Any messages you type there will be visible to all other Hotline and IRC Users. To issue a private message, simply call /msg <targetnick> message contents, like you would on a "normal" IRC server.

Caveats

Not all standard IRC commands are supported, unsupported commands will be replied by "421: Unknown command" followed by "NOTICE: HL Error". Issuing any other commands than "NICK" or "USER" as first command upon connecting to the server will be replied with "421: Unknown command" and will trigger a connection closure by the server. An exception is made for "CAP" commands such as "CAP LS" which are ignored before a "NICK" or "USER" command is received.

So far, Limechat on Mac, irssi and znc on Linux have been successfuly tested as client connecting to phxd's current version.
