[Twisted-Python] XMPP server connection question
by Gabriel Rossetti Dec. 5, 2008

Dec. 5, 2008

Hello everyone, I wrote an XMPP client and I have a question, when it tries to connect and the server is not listening, it doesn't send back an error and tries forever. I see that this function (twisted/names/srvconnect.py): def _ebGotServers(self, failure): failure.trap(DNSNameError) # Some DNS servers reply with NXDOMAIN when in fact there are # just no SRV records for that domain. Act as if we just got an # empty response and use fallback. self.… [View More]

[Twisted-Python] monitoring net resources with twisted
by Sidharth Jain Dec. 4, 2008

Dec. 4, 2008

I want to track a set network resources like Linux servers,hosts for network connectivity , and want to keep track of their activeness and possible inactivity due to network outage or any other reason. The hosts/serves I'm trying to monitor are regular Linux boxes with 2.6.x kernel. My personal preference would be a dynamic background heart-beat process which could sit on these servers/hosts and send periodic udp-packets to a master server to signal host activity and inactivity. As I'm quite … [View More]

[Twisted-Python] When would you considering split a server application to some physical instance with different logic function?
by Peter Cai Dec. 1, 2008

Dec. 1, 2008

Hi all, First, I am sorry because it's not a question related to twisted. But since twisted is a networking programming framework, you might be interested. Some of my colleagues have a view that a net work server should be split to small parts with different functions, either with processes communicating with socket, or with threads talking on message queues. Their points are these: 1. Each part could it's own state-machine, thus we could split big state-machines to decoupled small ones. … [View More]

Hi, I am starting using twisted with an IRC LogBot based on this ones : http://twistedmatrix.com/projects/words/documentation/examples/ircLogBot.py I customized it a little bit... When a user logs in (on the chan), I would like to send him a /CTCP user VERSION, read the reply and send onto the chan the VERSION name of this user. In the API, I found this : http://python.net/crew/mwh/apidocs/twisted.words.protocols.irc.IRCClient.ht… But it seems to be for the bot itself... How could I do … [View More]

[Twisted-Python] Create a standalone Unix executable for a Twisted application?
by Alessio Pace Dec. 1, 2008

Dec. 1, 2008

Hi, I'm pretty new to Python and Twisted, and I would like to know if anyone could share some experiences in creating a standalone Unix executable for a Twisted application I'm building. I would like in fact to distribute my application on some Unix machines (onto which I cannot install anything) which do *not* have Python and Twisted (and not even GCC). Thank you in advance for any suggestion. Regards, Alessio Pace.

Let me explain my problem.. I am building an uploader application using twisted. I am using "Protocol" in both side. What is the best way to seperate data? When i try to call "self.transport.write(data)" it doesnt send data immediately, it is sending with some other datas whic i send them later. Why doesnt it send, what for is it waiting? when i some information data I am sending with '\n' (there is no other '\n' in my data) to separate it in the client side but it is getting really … [View More]
