Expecting SSH to become available with the packer for too long

Question

Has anyone already encountered a package build problem?

Waiting for SSH to become available...
[INFO] Attempting SSH connection...
reconnecting to TCP connection for SSH
handshaking with SSH
handshake error: ssh: handshake failed: read tcp 127.0.0.1:49663->127.0.0.1:3278: wsarecv: Une connexion existante a dû être fermée par l’hôte distant.
[DEBUG] SSH handshake err: ssh: handshake failed: read tcp 127.0.0.1:49663->127.0.0.1:3278: wsarecv: Une connexion existante a dû être fermée par l’hôte distant.

My package collector is working correctly, but the step for connecting with ssh is very long (10 minutes).

Do you have an idea to solve this problem?

PS: the space character in the log is not my mistake, it's just the result of the -debug packer build. Perhaps to solve this problem, you can open another stackoverflow problem.

I have a similar setup (Ubuntu, Windows 7, virtualbox-iso). My scripts include the file below, which is called in the Providers block. Failure to do so may cause slowness.

#!/bin/sh -x

echo "UseDNS no" >> /etc/ssh/sshd_config;
echo "GSSAPIAuthentication no" >> /etc/ssh/sshd_config;
