a quick question about namespaces
by Jay donnell Feb. 2, 2005

Feb. 2, 2005

in the code below 'print locals()' shows mc2. What is the equivalent way to see the namespace that mc resides in? class myClass: --def func1(self): ----self.mc = 1 ----mc2 = 3 ----print 'in myClass.func1' ----print 'printing locals' ----print locals() ----print Google mungs up the spacing so I put a - in place of spaces. Does anyone know how to get around this spacing issue on google groups?

In this case the handler needs to be properly set up in either your httpd.conf or a .htaccess (assuming your configuration allows for that). > Whenever I access test.py from my browser it says "The page cannot be found" > , I have the file on /var/www/html, what did I miss? You don't access handlers like you do CGI. This problem likely lies in your configuration and not in your code. I would look at mod_python's documentation some more and probably start with mod_python's PublisherHandler for initial testing and experimentation. -Robey Holderith > Thanks in advance, > Joel

curl and popen2
by lists04＠gmail.com Feb. 2, 2005

Feb. 2, 2005

Hi, I have a problem with a curl request and running it under popen2. If I run this request from the command line: curl -i http://www.yahoo.com/test --stderr errfile (also tried redirecting stdderr to a file 2>, nothing) the file errfile is empty indicating no error with the request. However, when I do something similar in python: >>> cmd="curl -i http://www.yahoo.com/test" >>> output, input, err = popen2.popen3(cmd) >>> error = err.readlines() >>> error [' % Total % Received % Xferd Average Speed Time Curr.\n', ' Dload Upload Total Current Left Speed\n', '\r100 981 0 981 0 0 24525 0 --:--:-- 0:00:00 --:--:-- 24525\r100 2484 0 2484 0 0 62100 0 --:--:-- 0:00:00 --:--:-- 1467k\n'] I looked in the man page for curl, it doesnt say that it writes some bandwidth statistics to stderr. Am I missing something or is this better directed to some other newsgroup? TIA Hari

Tkinter on dual screen
by nik Feb. 2, 2005

Feb. 2, 2005

hello, i am writing an app which is running on a dual screen setup on windows and OS X. is anyone doing this using Tkinter? are there problems with it? i know Tk() takes a "screenname" argument which specifies the screen. but i am not sure about how well Tkinter copes with having two Tk objects and i could not find any documentation as to what the screens are called. - what are the screen names for screen 1 / 2 on windows / linux / OS X? - is there a Tk command that can check for multiple screens? ideally i would like something like names = getScreenNames() that tells me how many screens there are and what they are called. then i could write my app so that it runs on any OS and with any number of screens. all the examples i have seen so far rely on a platform-specific name which seems to come out of nowhere... - are you running dual screen Tkinter and is it working? what are the pitfalls? thanks for any help! nik

Re: getting data from a port in use

OK, know we know what you're actually trying to do. You should have told us that to start with rather than leading us down the wrong path with your little Python program. When asking for help, always clearly describe your _problem_ first. Asking what's wrong with a proposed solution without clearly describing the problem you're trying to solve just wastes time: http://www.catb.org/~esr/faqs/smart-questions.html > I already looked at some of the existing ones on Internet, but > they are not in Python (I am trying to learn Python!)

Pcap is your only hope unless you want to do a lot of rather nasty low level stuff (for which you'll probably have to write a bunch of C code that does all the things that libpcap does). You can't use the normal Python socket API to sniff data. You _could_ use popen to run tcpdump (which in turn uses pcap) and then parse the output from pcap. I've done both, and IMO using pcap directly is a lot easier. It's also your only hope of keeping up with any amount of traffic. http://sourceforge.net/projects/pylibpcap http://sourceforge.net/project/showfiles.php?group_id=14007&package_id=13826 Once upon a time, there was a rumor that somebody had a Win32 version of pylibpcap.

Does it connect, or fail to connect? Note that (as others have said) if you are trying to intercept data from an existing socket connection, this is not the way to do it. (This will let you use a port that another process has already claimed, and accept new connections to it). =Tony.Meyer

And you're sure that somebody tries to initiate a connection after your program has gotten to the accept() line? > When I set the port I use netstat (netstat -bn) to get the > ports that are in use. What do you mean by a port being "in use"? Is there another program already waiting for a connection on the port? You keep repeating the bit about "ports in use", but that phrase is too vague. Do you mean there is already an established connection that uses that port? If that's what you mean, it doesn't matter one way or another. What matters is whether there's another program already bound to that port and listening for new connections. As I've already said: if you're trying to get data from already established connections, you can't do it using accept. You have to use the pcap library. You're going to have to accurately describe what you're trying to do, or none of us are going to be able to help you. -- Grant Edwards grante Yow! HERE!! Put THIS at on!! I'm in CHARGE!! visi.com

This is the NAME line that appears in pydoc I think. If it did a full text search that would be much more useful, or at least a search through all the names of the functions & variables that are exported. ... My top wish for pydoc is to have the rest of the documentation in it!

Yes. I want to write a very small web sniffer that gets data from a specified port. I already looked at some of the existing ones on Internet, but they are not in Python (I am trying to learn Python!) and they have a lot more features that I want. Thanks for your suggestion.
