[Twisted-Python] Receiving a root from a pb client
Hi, I am using pb to communicate in a client-server configuration. My client inherits from PBClientFactory. My server has a remote_take_root() method by which the client can connect to the server and pass in its root, thus allowing two-way communication. Is there anyway for the server to re-establish the connection (should it go down) in this setup, or is this the sole responsibility of the client?

I don't see any response from the experts, so I'll say what I think: No. There is no way. One side has to listen, the other has to connect. You can make the network symmetric only by having both sides listen on different occasions - that means that for the server to initiate a connection, the client has to become a server itself. This is how TCP works. HTH. On 21/12/05, william.lewis@uk.bnpparibas.com <william.lewis@uk.bnpparibas.com> wrote:
Hi, first off all: - The only different between client and server in a twisted application is the way to etablish a connection. - The server listen, the client makes the connection. For the needs to re-connect after the connection had lost, use the "ReconnectingPBClientFactory" defined pbutil.py from the buildbot source. I use it to handle bad internet connection, that often lost the connection. With this factory and the a client that derived from pb.Root you could get the Root of the client at server side after a connection have been etablished. Hope that helps.
