RE: Client is unable to connect to server

[Steve Huston]

The tcpdump shows the TCP connection opening. What happens further along
in the connection?
 
Also, can you run the broker with more logging? Maybe add -t to the
command options.

Subject: Client is unable to connect to server



Hello,

 

                I’m facing a connection problem with
qpidc-0.5.752581-34.el5 when trying to connect to the C++ broker (same
version).

 

                My exception handler logs only “Connection closed” on
this line:

 

        } catch(const std::exception& error) {

                TrrQueueLog(ctx, "In function [%s]: [%s]", __FUNCTION__,
error.what());

 

                And a tcpdump only shows the TCP connection (which the
server seems to be refusing):

                No log is generated on the server.

 

                I’m clueless about what the problem could be. I do can
telnet the server on port 5672. Any ideias?
