Question

当我尝试启动ssh systemctl start ssh时，出现以下错误

Job for ssh.service failed because the control process exited with error code.
See "systemctl status ssh.service" and "journalctl -xe" for details.

我在systemctl status ssh.service之后得到的结果是

我尝试了sshd -t命令，结果如下

/etc/ssh/sshd_config: line 122: Bad configuration option: net.core.netdev_max_backlog
/etc/ssh/sshd_config: terminating, 1 bad configuration options

，值为net.core.netdev_max_backlog = 3000

我尝试取消安装-重新安装ssh没有任何反应有什么想法怎么办？谢谢

Answer 1

net.core.netdev_max_backlog不应位于/etc/ssh/sshd_config中，而应位于/etc/sysctl.conf

中

ssh无法启动，配置选项错误
