SFTP问题 – 权限被拒绝

我们正在尝试从大型机到新的Linux服务器做SFTP文件。 我们提供了我们的（大型机）公钥给目标服务器团队，他们configuration了这个。 发送文件时，我们收到以下错误：

我们如何解决这个问题？ 目前一些SFTP运行良好多年，对于新configuration我们正面临这个问题。

 debug1: Offering public key: /export/home/HEATFTP/.ssh/id_rsa debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey debug2: we did not send a packet, disable method debug1: No more authentication methods to try.
