scp远程拷贝文件时提示错误：
Warning: Permanently added '10.0.0.182' (RSA) to the list of known hosts.
Permission denied (publickey).
解决：
登录10.0.0.182，将/etc/ssh/sshd_config文件中的PasswordAuthentication no 改为PasswordAuthentication yes

重启sshd服务：/etc/init.d/sshd restart
问题解决。
原因：scp是基于ssh的拷贝服务，ssh在没有密钥登录的情况下，禁用了密码登录，故出现如上错误。
