回 3楼(cys) 的帖子

楼主您好，

好象您启动 sshd 的命令拼写有误喔，

而在 systemctl status 命令中，显示 sshd 服务是没有运行的状态（inactive）。

如我的一个系统 systemctl status sshd 输出信息如下：

$ systemctl status sshd
● ssh.service - OpenBSD Secure Shell server
   Loaded: loaded (/lib/systemd/system/ssh.service; enabled)
   Active: active (running) since Thu 2016-11-03 09:57:32 CST; 1 months 3 days ago
Main PID: 388 (sshd)
   CGroup: /system.slice/ssh.service
           ├─  388 /usr/sbin/sshd -D
           ├─10046 sshd: liujia [priv]
           ├─10048 sshd: liujia@pts/0
           ├─10049 sshd: liujia [priv]
           ├─10051 -bash
           ├─10071 sshd: liujia@notty
           ├─10073 /usr/lib/openssh/sftp-server

您好，

对比4楼和5楼里的命令输出结果，

5楼截图里少了 /usr/lib/openssh/sftp-server 这个进程的，

请问您曾修改过sshd的默认配置文件吗？

您好，

请问能贴出您的配置文件 /etc/ssh/sshd_config 内容信息吗？

如是否有这一行：

# Allow client to pass locale environment variables
AcceptEnv LANG LC_*

Subsystem sftp /usr/lib/openssh/sftp-server
