RK3399代码同步问题

在同步RK代码的时候执行命令：

./.repo/repo/repo sync -l
./.repo/repo/repo sync

遇到错误提示 ：

ssh_exchange_identification: read: Connection reset by peer
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
ssh_exchange_identification: read: Connection reset by peer

一直觉得是虚拟机配置问题，但是最后发现是公司的防火墙把RK的服务器封了：

Www.rockchip.com.cn (IP: 58.22.7.114) 端口：2222

跟公司的网络服务部门联系后得到了解决。
