Can't Send email to rediffmail server!!
by Abby 29 May '08

29 May '08

Hi, I am curently pursuing Master's in Computer Science from India. as i was working with Twisted Framework, a very powerful python framework, was not able to send email to rediffmail.com and yahoo mail server. The mail sent considered to be a SPAM,rejected by their server and entered in the records of www.spamhaus.org. But on the brighter side i successfully sent emails to cooltoad mail server as well as gmail server. previously i spent my time in configuring my mail server on my site and i found that my mail server was not announcing a proper HELO/EHLO. Also configured the server Authentication. Still am not able to send emails to these servers. it would be a great pleasure to hear a solution from twisted framework fine programmers. i am using a Apache JAMES mail server. Thanking you (ABHISHEK DEY)

help with twisted webserver and rpy script
by Jody Gugelhupf 28 May '08

28 May '08

hi there ppl :) i have a question, twisted is very new to me, i'm using the twisted webserver to control my tvcard, i wrote several scripts and got it all working, i also use a rpy script to switch stations from the website, only that it seems that i need to create for each station a rpy script, i'd rather have all stations in once rpy file and do it that way, i got it working in php, but is it possible to write php in rpy? here is an example of one of my rpy scripts to switch stations: #!/usr/bin/python import sys import os from www.web_types import HTMLResource, FreevoResource class TestResource(FreevoResource): def _render(self, request): fv = HTMLResource() fv.printHeader(_('LiveTV'), 'styles/main.css',selected=_('Test')) form = request.args command = "v4lctl setstation MTV" os.system(command) fv.res += "<html><script language=\"JavaScript\"> close();</script></html>" return String( fv.res ) resource = TestResource() the java stuff is so that when i click on the MTV.rpy link it closes the new window after the execution of the command, the main site where the MTV.rpy is displayed looks like this: #!/usr/bin/python import sys import os from www.web_types import HTMLResource, FreevoResource class TestResource(FreevoResource): def _render(self, request): fv = HTMLResource() fv.printHeader(_('LiveTV'), 'styles/main.css',selected=_('Test')) form = request.args fv.res += "<html>To start the stream server click <a href=\"http://10.0.0.1:8085/startstream.rpy\" target=\"_blank\">here.</a> To start the camera stream server click <a href=\"http://10.0.0.1:8085/startstreamcam.rpy\" target=\"_blank\">here.</a> To stop the stream-server click<a href=\"http://195.169.205.24:8085/stopstream.rpy\">here.</a> To switch to the channel you can simply click on the channel you want to watch. A new window will pop up and close itself automatically, then the channel should be changed.</html>" fv.res += "<html><br><a href=\"MTV.rpy\" target=\"_blank\"> MTV </a> <a href=\"TMF.rpy\" target=\"_blank\"> TMF </a> <a href=\"national.rpy\" target=\"_blank\"> National Geographic </a> <a href=\"discovery.rpy\" target=\"_blank\"> Discovery Channel </a> <a href=\"CNN.rpy\" target=\"_blank\"> CNN </a> <a href=\"BBC1.rpy\" target=\"_blank\"> BBC1 </a> <a href=\"BBC2.rpy\" target=\"_blank\"> BBC2 </a> <a href=\"net5.rpy\" target=\"_blank\"> Net5 </a> <a href=\"sbs6.rpy\" target=\"_blank\"> sbs6 </a> <a href=\"veronica.rpy\" target=\"_blank\"> Veronica </a> <a href=\"talpa.rpy\" target=\"_blank\"> talpa </a> <a href=\"rtl4.rpy\" target=\"_blank\"> rtl4 </a> <a href=\"rtl5.rpy\" target=\"_blank\"> rtl5 </a> <a href=\"rtl7.rpy\" target=\"_blank\"> rtl7 </a> <a href=\"een.rpy\" target=\"_blank\"> een </a> <a href=\"euronews.rpy\" target=\"_blank\"> Euronews </a> <a href=\"ard.rpy\" target=\"_blank\"> ARD </a> <a href=\"zdf.rpy\" target=\"_blank\"> ZDF </a> <a href=\"wdr.rpy\" target=\"_blank\"> WDR </a> <a href=\"gelderland.rpy\" target=\"_blank\"> TV Gelderland </a> <a href=\"ned1.rpy\" target=\"_blank\"> Nederland 1 </a> <a href=\"ned2.rpy\" target=\"_blank\"> Nederland 2 </a> <a href=\"ned3.rpy\" target=\"_blank\"> Nederland 3 </a> <a href=\"ketnet.rpy\" target=\"_blank\"> Ketnet/Canvas </a> <a href=\"lokal.rpy\" target=\"_blank\"> Lokaal Plus </a> <a href=\"upcinfo.rpy\" target=\"_blank\"> UpcInfo </a> <a href=\"trtint.rpy\" target=\"_blank\"> TRTint </a> <a href=\"rai1.rpy\" target=\"_blank\"> Rai Uno </a> <a href=\"eurosport.rpy\" target=\"_blank\"> Eurosport </a> <a href=\"nick.rpy\" target=\"_blank\"> Nick/Comedy Central </a> <a href=\"tellsell.rpy\" target=\"_blank\"> TellSell </a> <a href=\"tv5.rpy\" target=\"_blank\"> TV5 </a> <a href=\"cam.rpy\" target=\"_blank\"> cam </a></br></html>" fv.res += "<center><OBJECT ID=\"MediaPlayer\" WIDTH=320 HEIGHT=300 CLASSID=\"CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95\" STANDBY=\"Loading Windows Media Player components...\" TYPE=\"application/x-oleobject\" /><param name=\"autoStart\" value=\"true\" /><PARAM NAME=\"error\" VALUE=\"item\" /><PARAM NAME=\"stretchToFit\" VALUE=\"false\" /><PARAM NAME=\"ShowStatusBar\" VALUE=\"true\" /><PARAM NAME=\"FileName\" VALUE=\"mms://10.0.0.1:8083\" /> <EMBED TYPE=\"application/x-mplayer2\" SRC=\"mms://10.0.0.1:8083\"NAME=\"MediaPlayer\" WIDTH=320 HEIGHT=300 ShowStatusBar=\"1\" /></EMBED></OBJECT></center>" return String( fv.res ) resource = TestResource() as you can see and as i said i need to create for each station a rpy file, can i not somehow put it all in one or make php work in rpy? thx for any input :) jody :D __________________________________________________________________ Looking for the perfect gift?

Well, the penny finally dropped this morning and my understanding of nevow finally arrived! Its really something. I guess I am only aware of a small fraction of its power and flexibility, and already I have vertigo! I just wanted to say thanks for producing such a great framework. PHP is history! Regards Simon

Nevow Tables
by Simon Pickles 17 May '08

17 May '08

hmm, Well, I've met stan, and that is all good for handy supplied tuples, but I am having trouble integrating this with my lists from remote PBs. I've a little Nevow monitor app which is requesting data from a server and generating HTML from it, in theory. The comms are fine, but building a table of the supplied data is eluding me! Please get your red pen out: #----------------------- #import stuff class HttpServer(rend.Page): def __init__(self): self.broker = monitorBroker.PBroker("monitor", '127.0.0.1', 7021) self.docFactory = loaders.xmlfile('main.html') # includes <div nevow:render="serverData" /> def render_serverData(self, ctx): def useResult(data): return T.table(render=T.directive('sequence'))[ T.tr(pattern='header')[ T.th[ 'sID' ], T.th[ 'host' ] ], T.tr(pattern='item', render=T.directive('row')), T.tr(pattern='item', render=T.directive('row')) ] def render_row(self, ctx, rowData): return ctx.tag[ T.td[ rowData[0] ], T.td[ rowData[1] ] ] d = self.broker.DoRemoteCallFromMonitor(serverData.HUB_ZONEDATA) d.addCallback(useResult) return d #--------------------- The remote PB supplies data like this: (((0,0), "alpha"), ((0,1), "beta", ((1,0), "alpha"), ((1,1), "alpha")) representing the rows and cols of the table. Can anyone help beat my code into shape? Thanks Si

Passing data to render functions
by Simon Pickles 16 May '08

16 May '08

Hi, In the example below, I want to use a member of the class to process the HTML render request. How can I arrange my code to allow access to class members? # ----------------------------------------------------------- from nevow import loaders from nevow import rend from nevow import tags as T import monitorBroker class HttpServer(rend.Page): def __init__(self): def ServerInfo(self, ctx, data): self.broker.GetServerData() # self refers to WovenContext, not HttpServer, not happy! self.addSlash = True self.docFactory = loaders.stan( T.html [ T.head ( title = "TestMonitor" ), T.body [ T.h1[ "Test Monitor 0.1" ], T.div[ "HUB Server: ", ServerInfo] ] ] ) self.broker = monitorBroker.PBroker('127.0.0.1', 7021) #----------------- Thanks Simon

How to use twisted.web2 http clients.
by Brian Carmalt 14 May '08

14 May '08

Hello all, I have set up a twisted.web2 http server and would like to use the web2 client to connect to it. I have been using the httplib in Python, but it is tedious to use and has a significant(for my project) bug in it(no 100-continue support). I have asked a similar question a couple of months ago, Cameron Dale responded with an example of how he uses the http client in web2, but the the link he supplied is no longer available and I cannot seem to find a local copy. I looked at his example when he posted the link, but it did not seem like it was relevant to the cases I have. If I am wrong, could you post the example agian Cameron? Thanks. Here is what I need to implement: Streaming POST: 1) create connection 2) set up connection 3) check for a 100-continue and authenticate if necessary. 3) stream data over the connection, in small chunks with unknown content length or from files. 4) check the response. 5) close connection/or reuse it if I can. Multiple One-shot POST, GET, HEAD and DELETES 1) create connection 2) set up connection 3) authenticate if necessary. 3) send multiple POST/GET/HEAD/DELETE commands and retrieve the responses. 4) close connection when done. For the Streaming POSTs I need to support HTTP 1.1, chunked encoding, persistent connections and 100-continue. This means web2, as far as I can tell. The same for the one-shot requests, if I want to use persistent connections, I need web2. Is this correct? Or can I get the same functionality in web? If I have to use web2, could somebody help me in the right direction? If this is possible in web, then a hint in that direction and how i could do it would also be appriciated. Thank you, Brian
