Depends on your web server. But there's very probably all the needed
documention somewhere, and I'm pretty confident google will find it.

We don't have much specific information from you here, but taking a few guesses, it sounds like you have put a Python program in some directory that your Web server knows about, but when you visit the address in your browser that should let you use that program, you just see the program text, not the output of the program when it is run. What you need to do is to tell your Web server that the file is a "script". With Apache, for example, instead of using configuration directives like "Alias", you use "ScriptAlias" instead. Of course, Apache has lots of different ways to make files behave like scripts, and you may be using a completely different Web server, so a bit more information would be welcome. Still, one really simple method with Apache is to expose your program like this: ScriptAlias /myprogram "/home/me/programs/myprogram.py" Provided you set the permissions of myprogram.py to be readable and executable by the Web server user (if appropriate), and provided the Web server user can navigate to the /home/me/programs directory, you should at least get the program running. More configuration may be needed - why not let us know how far you get? Paul -- http://mail.python.org/mailman/listinfo/python-list
Lowest hassle Python web server?
I keep telling my friends that Python rocks. Now it's time to put my money where my mouth is. I'm about to start writing a server for a phone based game. It needs to handle simlpe requests from some Java code running on the phone at a fairly low transaction rate. There will also be a simple web site allowing users to edit preferences and so forth. I have just enough Python experience to decide that I prefer it over Java for this job. It'll be on a Linux box that I have full control over. I can see from FAQs that there are several possible ways of doing web server work in Python, e.g. Twisted or mod_python in Apache, etc. So I'm wondering: - Could you recommend a solution you've found to be the most convenient? - Does threading cause any more of a hassle in Python than Java? - Is there anything similar to JSP in Java?

Re: Lowest hassle Python web server?
- Does threading cause any more of a hassle in Python than Java? Hello, From the python docs, it states that the threading design is loosely based upon the java module. Certainly, coming from Java I had little trouble getting used to python threading. However heres some gotchyas : - The thing to beware of there is something in Python called the GIL. Read up about that before you start threading stuff - this will explain to you why there is no volatile keyword - this got me confused at first. - There is no synchronize keyword, instead you have to use locks which can be obtained from the threading module - There are no methods such as wait on an object (there is an event object you can get to call wait upon - again threading) - The handy concurrent stuff which has been introduced in J2SE5.0 mainly isn't in python - through you do get Queues in Python (maybe more, I dunno?) The GIL thing makes it easier to do threading with Python (there are disadvantages to the GIL but I won't get into that here - if you're interested read through the history on this group) but it's still threading so beware!

Basic Auth for simple web server

setting file permissions on a web server
I always read about how you need to set certain file permissions (for cgi files, for example), but it's never been clear to me *how* you do this. I know you can run the line chmod 755 scriptname.py but *where* do you run this? Is this done on your personal system, or on the server? What if you are using Windows? If it's done on the server, how do you do it? The only way I've figured out so far how to do this is to upload my cgi files to my server, then within my FTP program I right-click the file and change its permission number that way, but that seems an inefficient way to do it, especially having to do it each time. Is there a way to put the above line within the script perhaps, so that the script sets its permission automatically? Or do certain editors allow you to save files with a predetermined permission? Aside from my right-clicking method, I don't know how else to do it. -- http://mail.python.org/mailman/listinfo/python-list
Advice for Python and Web Server/Services?
I have recently discovered Python and like it quite a bit. I would like to use it on a new project I am starting. The project will gather data from several web services and present the collected data to browser users through a web server. So basically I need a full-time web server and a separate way to poll web services for their data. There is no database involved. The problem is that I have tried several Python web servers (CherryPy, Karrigell, etc) and they all have problems getting out through my Comcast cable modem. There is a 3 second pause every 10th file. Never the 9th or 11th, but always the 10th file. I thought maybe Comcast was limiting incomming HTTP but Apache does not do this so I'm stumped as to why it is happening with the Python servers. All servers work fine over the LAN. Anyway, I wanted to get some advice on what type of setup would be best for this using Apache. The web service polling needs to be going all the time so a straight CGI-type thing is not an option. I've looked in to fastcgi and mod_python but I'm not sure either is what I need. What I want is for my Python program to be polling the web services 24/7 and Apache to serve static pages by itself but call a function in my already running Python program for files with a certain extension (.xml for example). Have any of you done something like this before? Ideally, I'd like to figure out why the Python servers are having problems. This is a very low volume system so straight Python would be great if I can get it working. Thanks for any advice you can give. -- Ron Davis -- Ron Davis -- http://mail.python.org/mailman/listinfo/python-list

For instance, to enable authentication for user foo, you can do the following from paste.auth.basic import AuthBasicHandler def only_for_foo(env, user, passwd): return user == 'foo' and passwd = 'bar' auth_app = AuthBasicHandler( myapp, 'app realm', only_for_foo) (where myapp is your WSGI application, of course).

I guess this would be a good starting point: http://www.linuxcommand.org/man_pages/chmod1.html In short, chmod refers to local files so wherever you run it it will refer to files on that machine. You run it simply by typing it in a shell as a user who has privilage to perform the operatation, which can mean you have to be an owner of the file but if you are root you can do it in any case. Depending on your ftp, scp, http or whatever method you use to transfer files the file permissions may or may not change during the transfer. If permissions are kept intact you can chmod on your local machine and then transfer, if they are not then you transfer first and chmod on the server. When you transfer files from a windows machine to *nix it again depends on the particular method you choose how the permissions will be set. There is no way of putting this permission information into the file itself but some (most?) editors can be set to save the file with a permission of your choice. Hope this helps. -- http://mail.python.org/mailman/listinfo/python-list

Since I'm running Windows, I assume that I can't run the chmod line on my own computer. My web server uses Unix, but is it possible for me to have access to a command line for the server? I didn't know that was possible for basic web hosting plans (I'm using 1and1 right now). I suppose I could write a script that would set the permissions of all the files in a particular folder on my computer to 755, but is there a Windows equivalent command for chmod to do this?

Otherwise you might be able to create an ftplib-based script that will automate this over ftp. Diez -- http://mail.python.org/mailman/listinfo/python-list

Correct, chmod is a *nix command. > My web server > uses Unix, but is it possible for me to have access to a command line > for the server? This depends on your arrangements with your web server provider. Perhaps you are allowed to ssh into that machine, perhaps not, you need to ask your provider. In case you can use ssh, then you can log in with putty (an ssh client for windows, grab it from here: http://www.chiark.greenend.org.uk/~sgtatham/putty/) and you will have a command line on the server so you can run chmod there. > I didn't know that was possible for basic web hosting plans (I'm using 1and1 > right now).

I have next to zero experience with windows but as far as I know windows doesn't have file permissions at all (anyone, please correct me if I'm wrong :)) so in windows land it doesn't make any sense to "change file permissions". Even if it has some sort of a notion of file permissions I wouldn't know how that gets translated into unix. > Or am I stuck having to do it on the server side? I guess so. But that's not a terribly big problem even if you can't use ssh. What I would do is write a script (in python of course :)) that does the file permission changing and run that script over the web. Since this can have serious security implications my strategy would be to place this script somewhere which is not reachable through the web and only relocate it to a web accessible directory when you want to run it over the web, and when you are done, you place it back to its secure location so nobody can reach it.

There's probably a Windows-equiv of chmod for your own files, but it won't affect files placed on another machine. 3. You're stuck having to do it on the server side. Now a good ftp program can automate this for you, but it's still your job, not the servers.

Actually Windows has a quite good permission scheme, with full owner/group ACLs and granular permissions for read, write, append, delete, and several others I can't recall. The problem is no one uses them much. The manipulation tools are a pain, and developers routinely ignore them (including Microsoft's own developers, although I hear they've gotten much better lately). > I guess so.

You're right about the security concerns, but your solution sounds like more trouble than it's worth. With a bit more effort, you could write a local python script that acts as an ftp client and applies permissions remotely. But why bother when a good ftp client already has that built-in (and is much less likely to contain destructive bugs). > You can find out how to > write this script from http://docs.python.org/lib/os-file-dir.html You're worried about security and you turn a novice with a scripting language loose in the briar patch of unix permissions, on a remote server no less?

This is getting a little off-topic, I admit, but the NT-derived versions
of Windows do indeed have file permissions. The Windows-equivalent of
chmod (and chown) is cacls ("Change Access Control Lists"):
http://www.ss64.com/nt/cacls.html
In essence, each file has an owner and a list of other users and groups,
who may each have "Full control" (meaning they can change permissions),
read-only, write-only, read-write, or no access.
Windows 95 and its descendants don't have permissions any more than DOS
does. (Except with respect to Windows network file-sharing.)
(Heh, I checked just before posting this and someone beat me to it.
Here's my post anyway.) :-)

Turns out that my web hosting company provides ssh access on the next highest plan and up, but not mine. :) Oh well, I think I'll explore FileZilla a little more and see if there's more of an automated way to do it than just right-clicking each file (or even right-clicking multiple files at once, if possible).

Re: How to enable Python Scripts with MS IIS Web Server?
hi,
you should first install win32all :
http://starship.python.net/crew/mhammond/
next, 2 ways 2 proceed, but the first is the easier :
you make a "test.asp" page in the folder
at the top, you write <@Language=Python%>
a line below : <%Response.Write("Hello World")%>
try if the page works well. if it works then your python/iis install is
ok
the second way is to keep the .py extension and to associate it with the
python executable

connect to a remote web server & upload data from Python using ssh and scp
Hi all, I need to upload data ( text & image data ) to a remote web server from python. I came to know that i could do it using ssh and scp.but am not sure of how to do it. I don't want to use CGI for that . Can anyone help mehow to do it, and where i can get a good tutorial for doing thisI surfed the net..but could'nt find a good doc for this.. Thanks, for your time !

Well, the only difference between "server" and "web server" is that the latter is guaranteed to be listening, probably on port 80, to HTTP requests. If you want to avoid CGI (and, I assume, any other web-interface means of transferring files) then you need to know what *other* services the remote server is running. ssh/scp is one possibility, FTP is another. There are others (rsync or WebDAV, for example). It all depends on what's on offer. If you know the server in question will accept an ssh connection, then one simple solution is to call scp (or pscp from the Putty suite if you're on Win32) from the command line to copy the files you want. If you want to do it from within Python, then you could use os.system or os.popen or one of its cousins to do the same. eg, scp my_local_file.txt [EMAIL PROTECTED]: If you only mean: "I know it's theoretically possible to copy files to servers using ssh/scp but I don't about this particular server" then you'll need to determine whether the server in question will accept ssh connections, and whether you have the right to create such a connection. Try the above, and see if it works. TJG This e-mail has been scanned for all viruses by Star. The service is powered by MessageLabs.

Looking for a high performance web server written in Python, and supports CGI/FastCGI
Basically I am trying to find a high performance web server. Since Python is installed on all of the servers, It'll be great if the web server is written in Python as well. Otherwise, I will have to install lighttpd or other web servers. Then the largest issue with Python-based web servers is performance. That's why I start to look into medusa or twisted-based servers. Twisted seems too big and complicated for what I really want to do and the original medusa web server only has very basic functionality. And I'd like the web server to have CGI/FastCGI and possible SCGI support for flexibility in application development. My applications here are really internal testing or data provider tools. Am I asking a lot? I think this is basic requirement for a web server these days :D What it looks like is that, although there seem to be many Python http servers available, there isn't really one that's simple, fast and feature-rich (cgi/fcgi/scgi) - I guess I am asking too much ;-p It seems that the only candidate that meetings the requirements but "written in Python" is lighttpd. Any recommendations? -- http://mail.python.org/mailman/listinfo/python-list

Keep in mind that since you're only looking for a web server, 90% of Twisted won't even come into play for you. If you want, you can even install *only* the webserver (of course, unless you're on an embedded platform where disk space is at a premium there's not really much point). A bigger problem, I reckon, is that twisted.web doesn't support FastCGI and twisted.web2 is still a moving target. You haven't really said much about your requirements though. Perhaps if you describe them in more detail (for example, what does "high performance" mean to you?) someone can make a more useful recommendation.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
To be honest, I'm not sure what kind of performance I can get even with medusa or twisted. I assume it won't be as fast as servers written in C/C++ and use async sockets, but should be much better than multi-processed or multi-threaded servers in written in Python. Not sure if anyone else has an idea about medusa or twisted performance. Any chance that it's close to Apache? But even so, I guess I may still have to go with lighttpd for FastCGI/ CGI/SCGI support. > You haven't really said much about your requirements though.

Just use one of the several high quality open source webservers. lighttpd is a great web server. I just didn't want to bother download the source, configure, make and make install, and have a bunch of files installed into the system (The binaries are mostly not the latest version.) If a server can be set up with a few python files, it sounds like a cleaner approach :) lighttpd does have an option to make a monilithic build that has everything in one file but somehow I couldn't make the scons-based build work.

Just use one of the several high quality open source webservers. If it is a Python web server, it would be nice to extend it by putting code right into the web server. The performance should be better than FastCGI because it removes the cost to send the requests/replies back and forth. -- http://mail.python.org/mailman/listinfo/python-list
Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
I just did some testing between CherryPy's web server and lighttpd. My test was very simple and I used ab.exe for this purpose. CherryPy web server can serve about 140 simple request / second, while lighttpd can handle around 400 concurrent requests. > You haven't really said much about your requirements though.

If you disable the Reverse-DNS lookups in one of the python (not Karrigell) web modules (I'll dig out a previous post somewhere about this), it speeds up karrigell tremendously, my apps aren't huge, but I have no problems with karrigell across the internet :) -- http://mail.python.org/mailman/listinfo/python-list
Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
I wrote the last posting at late late night and I didn't know what I was typing at that time ;-p I didn't mean the test with CherryPy was not concurrent connections, or the test with lighttpd was all concurrent connections. I actually tried both concurrent (-c in ab command line) and non-concurrent (without -c in ab command line) and I tried the threading and threadpooling in CherryPy. The result did not vary much. This article http://www.cherrypy.org/wiki/CherryPySpeed says CherryPy can process around 400-500 requests/second. It's set up is: Pentium M 1.6, 1G RAM, Windows XP2 laptop, test done with apache 2.0.41 ab. I have a slightly better hardware set up: Pentium M 1.7MHz, 1.5G RAM on Windows XP2 laptop, test done with Apache 2.2 ab However, I don't get even close. The best I get is around 140 requests/second. I'm using the same test script as the CherryPy test with slight modification just to make it run. As a matter of fact, the Cygwin build of lighttpd only gets around 430 requests/second for a 2-byte static file. I disabled firewall and antivirus on the box when tests were done. Any idea about the huge difference? It would be very interesting if some CherryPy (or python) users can post their performance benchmarks.

It would be good to know which version of CherryPy you are using. That wiki page is talking about the CP 2.0 branch; 2.1 and later are quite different. If you have a later version, try using cherrypy/test/benchmark.py Note also that you can use lighttpd as an HTTP server for CherryPy apps via FCGI/SCGI.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
You are right. Load test can be complicated because of the various patterns of web applications and usages. The simple tests I mentioned and conducted just give myself some idea about the performance. Given the same set up, some numbers should be comparable and reveal some aspects on web servers' performance. They are by no means formal load tests, but they are helpful to me :-) "Istvan Albert" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] >> >> I will have to install lighttpd or other web servers. > >> If it is a Python web server, it would be nice to extend it by putting >> code >> right into the web server.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
Just thought I'd mention it. As stated in some posts I put on the list in the last few days, I'm working on a FastCGI server for python. Of course its not as fast as lighttpd, but I think it still has many applications. I've currently got a *very* simple prototype, but I expect the finished module to subclass BaseHTTPRequestHandler and work similar to the CGIHTTPServer module. I'll let everyone know when its ready, and you can try it out if you like ;) -- mthorley -- http://mail.python.org/mailman/listinfo/python-list

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI
Thanks Tim and Gerard for recommending karrigell. I just checked it out. It is indeed a nice package. However, I didn't find it easier to learn or use than CherryPy though. I read through CherryPy tutorials and have got a good idea how to use it. I also read Karrigell docs. The way Karrigell uses subpath behind CGI file name is a little strange to me. Nonetheless, Karrigell looks very nice to me but I may start with CherryPy. What's missing (according to my requirement/wishlist) is, as a web server, the build-in web server does not handle CGI or FastCGI apps, making python the only way to write apps...
