scp和rsync不起作用(ssh工作)

概述在我的Debian Squeeze服务器中,scp和rsync似乎没有复制任何内容.适用于其他服务器(因此不是客户端问题).使用scp时,它只是创建一个空文件并等待. /etc/bash.bashrc包含[-z“$PS1”]&&也回到顶部. SSH工作正常.可能是什么问题？ 诊断 foo.bar：大小为10899字节的纯文本文件 scp -vvv /tmp/foo.bar服务器：/ tmp Exe 在我的Debian Squeeze服务器中,scp和rsync似乎没有复制任何内容.适用于其他服务器(因此不是客户端问题).使用scp时,它只是创建一个空文件并等待. /etc/bash.bashrc包含[-z“$PS1”]&&也回到顶部.

推理：不是客户端问题,因为scp和rsync可以与其他服务器一起正常工作

采取的步骤

> OpenSSH服务器已被删除,清除并重新安装
> .ssh /和其中文件的调整权限

解决方法 我怀疑行为不端的服务器在〜/ .bashrc,〜/ .profile或其他启动脚本中有一些不寻常的东西.每次我看到类似的行为,都会在.bashrc或类似的东西上有一些自动运行软件. 总结
