Re: Client/Server Question
The subprocess module didn't work here. I tried using os.popen(), that won't help it either. What I am trying to achieve is that the server daemon is sitting and listening to command from the client. As client send MaxSim it launches MaxSim.exe and then again waits for subsequent commands. Support client sends DrivingSim it should launch DrivingSim.exe etc. It does till client sends a SHUTODWN message upon which it shuts down itself. Any pointers to achieve this more seamlessly.

Re: Client/Server Question
The recv() might return MaxiSimDriving Sim. It could return MaxiS on one call, and im on the next. If the remote side closes the connection, recv() will keep returning the empty string, and your program will be stuck in an infinite loop. How to overcome this problem ? Did you understand Faulkner's suggustion? Anyone who connects to TCP port 2000 can invoke shutdown -s (which I assume shuts down your host). I did, anyone who connects to port 2000 might be able to send a shutdown and close the computer. I am aware that its not the best way to achieve this but my app runs on a small network without actually connecting to internet.

How to write a Installer for a Python App in Linux

I found on the web python2.4 and the corresponding wxPython files. How can I write a Installer file which will install all the needed programs in the correct path, so that my wxPython app is ready to run and end user doesn't need to bother installing required files.

Network Game in Python
I have to create a small and simple GUI app in Python which is similar to a netwrok game. Let me expalain you. I need some suggestions. I might use wxPython for GUI because that is the only GUI oolkit I know. There are 6 players in the game. They are all connected though a LAN (possible an internal network). There is one main supervirsor who starts the game and other 5 are players. Once the supervisor starts the game, a move goes randomly to any player out of the 5 players. Once a player gets a move he has to act. Based on his action next move will be generated by supervisor and sent to some other player in the network. This process goes on untill the simulation time ends. Winners and Loosers are decided by some point system which supervisor keeps track of. Some questions I have are: 1. How can I manage network messages among the players. Should multicast be used or Actor should send the message to Supervisor and he sends to all. ? What python modules can be handy in these things. 2. How can I manage moves among players. What move a player makes is visible to all others in real time, so essentially all players have the same consistent view of the game. Only the person with access can actually make a move or carry out action. Any suggestion how to carry out this thing. 3. Shold I use a flat file or some database in mySQL to measure points etc ? I want to have a repository which keep tracks of all the mvoes in the system and who played what move etc..? Any suggestions on this. 4. If you have any other input, it will be greatly appreciated.

Now my task is to find the shortest distance from each node to every other node. And finally I want to find is the average distance from one node to another node in the graph. This is an average Erdos number or equivalently what degree of seperation exists in the graph. I can start with low values of N and D but my ultimate aim is to simulate this graph on big values of N and D. Every help is greatly appreciated.

This structure is surely quite sparse, so you don't need to store the edges in a matrix, you can manage is as a sparse structure, and maybe you don't need a Blue Gene.

str02=mac_string[2:4]
str03=mac_string[4:6]
str04=mac_string[6:8]
str05=mac_string[8:10]

I also tried like this

Untested:
from twisted.internet import protocol, reactor
from twisted.protocols import basic
COMMANDS = {
xterm: (/usr/bin/xterm, {DISPLAY: :1.0}),
}
class CommandLauncher(basic.LineReceiver):
def lineReceived(self, line):
try:
cmd, env = COMMANDS[line]
except KeyError:
self.sendLine(error)
else:
reactor.spawnProcess(None, cmd, env=env)
self.sendLine(okay)
f = protocol.ServerFactory()
f.protocol = CommandLauncher
reactor.listenTCP(12345, f)
reactor.run()
You should be able to telnet to this (port 12345) and type in
names of commands for it to run. Of course, xterm isn't a very
good win32 program to run but I couldn't think of a better example.
You could also write a program to send command requests to this
server, instead of using telnet.

If the username is different from your system login this can be changed to :

Hi Avell,

different. May be you can guide me.
I have a linux box, from where I remotely execute all the commands. The
remote machine is windows machine. I installed an OpenSSH server for
windows to send the shutdown command. I setup the public keys in such a
way that I could login to SSH server without using password.
I used
import os
os.system('ssh [EMAIL PROTECTED] shutdown -s')
I was wondering how can I interact with an application . Since you
mentioned about subprocess module, I want a ability that my PYthon
script can actually interact with the windows box and launch and close
application there remotely.
Any suggestions on how to do this ?

I just started to write a small project in Python. I was wondering if there can be something like remote boot manager. I have to remotely start a computer. It has dual boot (WinXP and Linux). My remote computer is Linux which will send command to remotely boot the other computer. Can we write python script or some utility which would let us select the Operating System to boot ? For example If we send parameter WIN it boots into Windows and if we send NIX it boots into Linux. Every help is appreciated. Thanks -- http://mail.python.org/mailman/listinfo/python-list
Re: OS specific command in Python
When you connect (via ssh or telnet) to a remote machine, you need to type (manually) your username and your password. Programming that is never easy. I have setup the public keys to AUTO LOGIN so that it doesn't ask the password. -- http://mail.python.org/mailman/listinfo/python-list

OS specific command in Python
I want to write a python program and call OS specific commands in it. So basically, instead of typing in on the command line argument I want to have it in a python program and let it do the action. for example. in my program I would want to call the ssh feature like one does on the command line ssh [EMAIL PROTECTED] .etc How can I do this easily ?

Re: wxPython GUI designer
Are there any good commercial project built with wx ? I am a newbie and a have to write a small application in Python. I was wondering which optin would be best for me in terms of least learning curve and getting the final product ASAP. Thanks DH wrote: In my opinion none of the wx* or gtk* related designer tools are any good. QT Designer (which can be used with pyqt) is excellent, however, you probably would only want to use that if you are developing non-commercial software or else can afford a commercial license from Trolltech. For wx and gtk projects, I usually just write the gui by hand like you have already been doing. -- http://mail.python.org/mailman/listinfo/python-list

Have you tried looking at the code in the wxPython demo? In the ListBox

supported.

wxPython question
I tried to follow wxPython Demo examples to understand it better. I used wxGlade to generate my code from the GUI builder. When I try to see the code for Menu and Menubar I see a little mismatch in the way functions are being used. For example, wxGlade produces code like this self.Action = wx.Menu() self.AddComputer = wx.MenuItem(self.Action, wx.NewId(), _(Add Computer), ,wx.ITEM_NORMAL) self.Action.AppendItem(self.AddComputer) ## Code end and in the demo it is gives as self.Action = wx.Menu() Action.append(201, Add Computer) # Code end Can somebody please explain this discrepancy ?

Customized Boot Manager in Python
I have to create a small visual interface program called as Boot Manager which is customized accoring to the needs. I have around 8 pc's and 2 linux boxes. One Linux box is always on and all other are closed in sleep state. I have to perform the following things: 1. Boot up all of them. I used Wake on LAN and wrote a small python script for that. It works fine. 2. To shutdown all pc's when the work is done. For this I installed an OpenSSH server for Windows in PC. When I send a command using ssh it shuts it down. Now, I have to create a visual interface for such kind of small program.

My program is a simulation program with four classes and it mimics bit

attributes and my program kinds of tries to keep tab of everything. As
I mentioned its a simulation program, it starts at time T=0 and goes on
untill all nodes have recieved all parts of the file(BitTorrent
concept). The ending time goes to thousands of seconds. In each sec I
process all the 2000 nodes.

For all nodes in the system{

You don't show any sample of code or data... Nor do you mention what

Many systems do not return /allocated/ memory to the OS until the

Re: Memory leak in Python
The amount of data I read in is actually small.
If you see my algorithm above it deals with 2000 nodes and each node
has ot of attributes.
When I close the program my computer becomes stable and performs as
usual. I check the performance in Performance monitor and using top
and the total memory is being used and on top of that around half a gig
swap memory is also being used.
Please give some helpful pointers to overcome such memory errors.
I revisited my code to find nothing so obvious which would let this
leak happen. How to kill cross references in the program. I am kinda
newbie and not completely aware of the finetuning such programming
process.

Just a hint : if you're trying to load your whole huge data set in
memory, you're in for trouble whatever the language - for an example,
doing a 'buf = openedFile.read()' on a 100 gig file may not be a good

I was taking look at wxPython, pyGTK etc. Please suggest me the most simplest and easiest one as I dont need super cool aesthetics just a plain simple GUI app. Thanks -- http://mail.python.org/mailman/listinfo/python-list

Python and C
I was a C Programmer for a while. Lately started to learn Python for one small project at school. I joined a small company where they use C++ for development. Can we use Python and C together ? I mean create some classes in Python and some number crunching algorithms coded in C (for speed) and integreate both of them. Could somebody just show a real small example or give pointers to the same. Thanks -- http://mail.python.org/mailman/listinfo/python-list
