Mastermind Networking Lib - 4.1.3

Version 4.1.3 released! This is a minor release that improves the examples.

Version 4.1.2 released! This is a minor release fixing a few problems. Remote server example not set up yet.

Version 4.1.1 released! This is a minor release fixing mostly syntactic errors. By next release, I hope to set up a remote server example to run for the forseeable future.

Version 4.1.0 released (versions 2.0.0, 3.0.0, and 4.0.0 were pre-release work, and were mostly false starts on the rewrite)!

Most of the client and server code handles a GUI, which isn't important to understanding how to use Mastermind. You should see Docs.txt if you just want a simple example.

this version(Mastermind Networking Lib - 1.5.2 - Jan 17, 2009) work very well for me but i don't understand the python code can you put in server and client file more comments???
Thanks its only two day tha i programm in pygame, i programm very well in python but i don't understand all... thanks a lot!!!! Maybe a video guid ;)

This is pretty good, maybe make a feature to give the user the ip address of the sender.

def address(self,sock,host,port,address):return address

? I have little understanding in what you've coded in the netbase.py file, so I wouldn't know how to make it myself :P

"my computers ip on the network" = the ip of the server computer

I made another try and made it work!

This is what I did (It might be obvious but it confused me). Connecting localhost only makes the server reachable on the same computer. So I switched "localhost" in both server and client to my computers ip on the network. This allowed me to connect from any computer in the network to my server.

I'm a network noob and confused about the meaning of 'localhost'. On my computer it was translated to an ip local to the computer itself (not an ip used on the LAN). This might not be standard though.

Hi, yes, pymike's server is presently down, so that wouldn't work. It should work immediately--the underlying sockets library seems to handle everything automatically (e.g., I did nothing special to wirelessly connect to a router linked to a DSL modem). You have to make sure you're connecting to a server (pymike.pynguins.com, or an IP). If the computer is on the same LAN, you should probably be using localhost.

Oh, if the printout would puzzle you: I've replaced the "localhost" entry in the code with a variable that ables me to enter the host adress through raw_input.

Looks very promising. But I can only make it work connecting to a localhost server. If I try to run the server on another computer in the network and try to connect to it or if I try pimike's server I get:

File "client_tcp.py", line 17, in <module>
client.connect(host,6317)
File "/home/perf/Skrivbord/Mastermind 1.5.2/Net/netbase.py", line 123, in connect
raise SocketError("The connection could not be opened. It must be created first with a server object.")
Net.errors.SocketError: 'The connection could not be opened. It must be created first with a server object.'

Are there any configurations in the local network that should be done first? Should the router be configured? Ports be opened (not when running within the local network no?)?

I'm using the example client and server applications on version 1.5.2

Make sure your webhost supports running Python. Then FTP to the server, and run your server file. I suggest contacting pymike, who knows more about it.

very good. It works fine for network, but how can i create a "local" server, where others can join through the internet?

This looks pretty promising :) Can't wait to download it!

You have to wait for it to contact the server. For example, in the client, a constant loop is set up (i.e., it sends, then checks every time around the loop in Update() for a response from the server. If it gets one, it copies the response to the chat, and sends again, completing the cycle). When a chat message is sent from the client, the server adds it to the chat. Notice how when other clients ask for a copy of the chat for the server, they'll get the new, updated version of the chat. It's best to ask me questions about my stuff at ian@geometrian.com.

ok, I figured it out and the examples run ok.

I'm trying to learn the concept of mastermind but can't get the client/server logic. Let's say we have two clients connected to a server. If using self.send_data(data) in server.py to respond the client-sender, how can I send the same data to the other clients(not the client-sender)?

What's your Python version? It works in Python 2.5.

I'm new to Python networking and I can't get the examples working:

./server_udp.py
./server_udp.py: line 3: syntax error near unexpected token `os.path.split'
'/server_udp.py: line 3: `sys.path.append(os.path.split(sys.path[0])[0])

Version 1.5.2 released!
There are presently no servers online.

The new server is at: pymike.pynguins.com:6317
Change the relevant line in client.py to connect.

This seems great, I'll definitely keep an eye on it. :)

Actually, I've decided to rename this release 1.5.1 due to the tiny size of the fix.

Version 1.6.0 released!

Yes. Currently, just switch the commenting on lines 16 and 17 in client.py. The docs reiterate that too.

Lookin' good! The server is up on pymike.4rensics.org:6317 if you wanna see it working.

Version 1.5.0 released!

Definitely! Thanks for that.
I've isolated the problem (yes this version works, but not effectively enough for realtime client framerate thingies--a big caveat for games). I've been pretty busy lately, but I finally got something which should fix all of the problems. I completely reworked the select.select() function (so no guesswork) and the test seems to work with multiple clients. I'll be building it into the library later today ;)

The new version is great.

By the way, wouldn't it be easier to do this in "netbase.py":
try:import cPickle
except:import pickle as cPickle
[...]
data = cPickle.dumps(Packet(data))

instead of:
try:import cPickle
except:import pickle
[...]
try:
data = cPickle.dumps(Packet(data))
except:
data = pickle.dumps(Packet(data))
data = str(len(data))+"||"+data

Right ;)

Don't download this version... it has a bug. Ian's working it out ;-)

Version 1.3.0 released! (Version 1.2.0 was pre-release work).

PyMike is referring to the next release of Mastermind, which should hopefully be coming soon. :-D

I'm pretty sure "Anonymous chatting" is meant as a shortcoming, in which case, you will be glad to know that it has indeed been fixed (small mod on the client). In addition, I've made the library about twice as fast (depending on implementation) due to my removing unneeded data transfer.

I'm presently working on making an example of a client which is independent of the server's update rate (i.e., a slow server does not equal a slow game), but have encountered delaying troubles with the unavoidable use of multiple sockets.

Hehe fun stuff :-D I think the latest version fixed that though :-D

Wow! Anonymous chatting!

Thanks, PyMike!

Version 1.1.0 released!
Fixes a minor bug, making the server more crash proof in online scenarios.

Very cool :)

For everyone else: The server.py script is running on pymike.4rensics.org:6317
If you want to connect to it, change line 7 in client.py to:

client.connect("pymike.4rensics.org",6317)

If anyone abuses this then I'll have to take it down. It's only up for "proof that it works" ;-) Ciao!

Version 1.0.0 released!
