我正在尝试配置 ubuntu vps。我已经使用本地计算机上的 rsa 公钥和私钥设置了 ssh 安全登录。
除了禁用 root 登录之外，我还设置了 iptables 并配置为允许端口 80 和 22（仅来自我的 ip 地址的端口 22）用于 ssh 隧道。
我可以使用 ssh 正常连接，但当我尝试从本地机器使用 scp 时
sudo scp /var/www/filetocopy user@remoteaddress:/var/www/filetocopy
我收到这个错误
Permission denied (publickey).
我添加了 -v 来显示输出
Executing: program /usr/bin/ssh host ip.add.re.ss, user username, command scp -v -t -- /var/www/filetocopy

再次感谢您迄今为止的帮助

我唯一能得到与您相同结果的方法是从远程主机中删除authorized_keys。检查中的公钥是否与user@remoteaddress:~/.ssh/authorized_keys本地计算机上用户的身份文件匹配。
