我正在尝试使用root用户SSH连接到我的Debian 8.5.密码是正确的,因为我可以使用本地控制台登录Debian.在/ etc / ssh / sshd_config中PermitRootLogin等于yes,并且多次重启服务器以确保采取此更改.
grep PermitRootLogin /etc/ssh/sshd_config PermitRootLogin yes
我怎么解决这个问题？
运行sudo tail /var/log/auth.log：
Nov 29 07:40:06 mydeb sshd[2530]: User root from ::1 not allowed because none of user's groups are listed in AllowGroups Nov 29 07:40:06 mydeb sshd[2530]: input_userauth_request: invalid user root [preauth] Nov 29 07:40:07 mydeb sshd[2530]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=::1 user=root Nov 29 07:40:09 mydeb sshd[2530]: Failed password for invalid user root from ::1 port 41079 ssh2 Nov 29 07:40:14 mydeb sshd[2530]: Failed password for invalid user root from ::1 port 41079 ssh2 Nov 29 07:40:16 mydeb sshd[2530]: Failed password for invalid user root from ::1 port 41079 ssh2 Nov 29 07:40:16 mydeb sshd[2530]: Connection closed by ::1 [preauth] Nov 29 07:40:16 mydeb sshd[2530]: PAM 2 more authentication failures; logname= uid=0 euid=0 tty=ssh ruser= rhost=::1 user=root
解决方法
编辑/ etc / ssh / sshd_config并在以AllowGroups开头的行中添加root.这条线应该是这样的：
AllowGroups sudo sshuser root
按以下命令重启ssh服务：
service ssh restart
