scp 验证但只给出欢迎消息

Question

我想使用无密码 scp

scp -i ~/.ssh/id_rsa -P 2022 ~/report.pdf user1@myserver.com:~/

但我只得到

欢迎用户 1 访问 p6。 2015 年 1 月 28 日星期三 - 14:46 美国东部时间下午

我已经添加了必要的密钥并且显示了正确的身份验证。当我在详细模式下执行此操作时，我得到

有什么问题的线索吗？看起来无论我在目标机器上给它什么路径它都不在乎。

主要问题是在 ssh 会话开始时打印的统计信息和欢迎消息。唯一的解决方案是摆脱 .bashrc 或相关文件中的任何 echo 语句或任何可能打印一些统计消息行的脚本，例如 landscape.canonical.com 在 ubuntu.

中打印的消息

scp 验证但只给出欢迎消息

scp Authenticates but only gives the Welcome message

ssh

bash

scp
