错误的配置选项：AUTOCREATE_SERVER_KEY

我正在RHEL 6.7使用以下配置运行sshd

#   $OpenBSD: sshd_config,v 1.80 2008/07/02 02:24:18 djm Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a
# default value.

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0

# Disable legacy (protocol version 1) support in the server for new
# installations. In future the default will change to require explicit
# activation of protocol 1

当我启动sshd并且启动到AUTOCREATE_SERVER_KEYS=RSAONLY配置文件的第 23 行时，出现以下错误

Starting sshd: /etc/ssh/sshd_config: line 23: Bad configuration option: AUTOCREATE_SERVER_KEYS
/etc/ssh/sshd_config: terminating, 1 bad configuration options

我查看了 RHEL 文档和配置选项，它们说这是sshd配置文件的有效选项语法，如果是这种情况，为什么我的总是失败？

答案1

因为AUTOCREATE_SERVER_KEYS不在文件中有效/etc/ssh/sshd_config，但在/etc/sysconfig/sshd

答案2

AUTOCREATE_SERVER_KEYS=RSAONLY是属于 的服务设置/etc/sysconfig/sshd，而不是 sshd 配置的一部分/etc/ssh/sshd_config
