Vagrant up 和 ssh 在学校网络上不起作用

Question

我通过 WiFi 连接到学校的网络，当我尝试连接时vagrant up收到vagrant ssh以下消息：

流浪起来

    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection timeout. Retrying...
    default: Warning: Connection timeout. Retrying...

流浪者ssh

ssh_exchange_identification: read: Connection reset by peer

我怎样才能解决这个问题？
