[Qt-creator] Timeout during SSH connection

[Clifton Barnes]

I'm using Qt Creator 2.4.1 on Windows XP and attempting to connect to a Linux
computer, running Ubuntu 10.04 LTS, to use the Analyze features such as Valgrind 
Memory Analyzer.  I'm able to ssh to the Linux computer using PuTTY with my
password or a private key.  However, when I try either method through Qt Creator,
I get the message "Timeout waiting for reply from server."

On the Linux side, I get the following debug output from sshd:
sshd[5937]: Connection from 192.168.20.101 port 3885
sshd[5937]: debug1: Client protocol version 2.0; client software version QtCreator
sshd[5937]: debug1: no match: QtCreator
sshd[5937]: debug1: Enabling compatibility mode for protocol 2.0
sshd[5937]: debug1: Local version string SSH-2.0-OpenSSH_4.3
sshd[5937]: debug1: list_hostkey_types: ssh-rsa,ssh-dss
sshd[5937]: debug1: SSH2_MSG_KEXINIT sent
sshd[5937]: Received disconnect from 192.168.20.101: 11:
sshd[5937]: debug1: do_cleanup

So, it appears that the Linux side did not receive the SSH2_MSG_KEXINIT response
message and therefore did not continue the authentication procedure.  Qt Creator
then timed out and sent the disconnect message.

Is there a particular configuration that needs to be done on the Linux side to 
support this connection?  
Does Qt Creator use a different connection scheme than PuTTY?
Is there more information that I can send to help diagnose the problem?
