[Twisted-Python] PB and Woven authentication
by Justin Johnson Oct. 7, 2003

Oct. 7, 2003

I know there have been other posts on this topic, but I wasn't sure how up-to-date they are. I currently have a PB server that I connect to via the command line. It allows me to do tasks on wintel servers I manage. I'm now trying to create a web interface to that service using woven. Below is what I'm currently doing for authentication. First of all, am I doing things right below? Any corrections or suggestions for improvement? Once that is correct, how do I hook this up to woven? I was … [View More]

[Twisted-Python] Adapter troubles - Copying Quotient's DivmodSession
by Justin Johnson Oct. 7, 2003

Oct. 7, 2003

Hi, I've created a class called RatControlSession similar to DivmodSession in Quotient. I define IRatControlSession and RatControlSession, and I register RatControlSession as an adapter from twisted.web.server.Session to IRatControlSession. However, when I try to do something like... prefs = webinterfaces.IRatControlSession(request.getSession()) I get the following error. This is a cut-n-paste from what appears in the browser. ----- C:\svn\RatControl\ratcontrol\web\pages.py, line 14 … [View More]

[Twisted-Python] woven authentications and connections.
by Syver Enstad Oct. 7, 2003

Oct. 7, 2003

I am in the process of implementing authentication for an intranet application using woven. I will be storing the login information in the session. On each request I will connect to the database and pass the connection to the page handling the request. How do I know when the request is finished so that I can close the connection?

[Twisted-Python] SSH client bad packet length
by Anders Bruun Olsen Oct. 7, 2003

Oct. 7, 2003

Hi, I am trying to learn a bit of Twisted in order to make an app that will use SSH for running commands on remote hosts. I have followed the SSH howto on the homepage where I have changed it to accept any fingerprint and have put my own private and public keys in instead of the ones from the example and have it connecting to a server of mine that accepts passwordless key-auth. Lastly I have enabled logging to stdout (it might be an idea to add to the howto which module to import to get the … [View More]

[Twisted-Python] callFromThread with return
by Egor Cheshkov Oct. 7, 2003

Oct. 7, 2003

Hello! Suppose I run task in worker thread (e.g. database transaction) and I need to do some IO (PB call) and get the result from it during transaction. Since I run not in reactor's thread it's ok to block and wait for the result. I know that there is callFromThread but it never return any result. Is it possible to implement something like callFromThread that can block, wait for result and return it? Thanks in advance, Egor.

I have tryed different things but non seems to work. Please help ! Actually I have a simple data model interface that has a … [View More]

Just curious -- this is line 436 et seq. in the CVS version of t.i.defer.gatherResults ... if fireOnOneErrback: raise "This function was previously totally, totally broken. Please fix your code to behave as documented." Anyone know if this is still the case? - Steve.

[Twisted-Python] Twisted.Names question
by Rudy Schockaert Oct. 6, 2003

Oct. 6, 2003

How can I return a referral to another server when I cannot resolve the query myself? My setup would be as follows: I have a Twisted Names master server and a number of Twisted Names slave servers. The master server is only to be used by the DNS clients when the slave server is not available. The Twisted Names servers can only answer very specific queries. All other responses have to come from the Internet. My idea is to configure the clients as follows: Primary DNS server: Twisted … [View More]

[Twisted-Python] shut down only half the connection?
by Greg Oct. 5, 2003

Oct. 5, 2003

Using internet.protocol Protocol, is it is possible to close only the writing half of a connection, like would be done with "shutdown(1)" using the Python Socket module? transport.loseConnection() seems to close down the connection alltogether, at which point Protocol.dataReceived() never gets called. Thanks.
