# 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

起動して構成ファイルの行23sshdで起動すると、次のエラーが発生します。AUTOCREATE_SERVER_KEYS=RSAONLY

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

RHELのドキュメントと設定オプションを見てみると、これはsshd設定ファイルの有効なオプション構文であると言われています。それでは、私の構文が常に失敗するのはなぜですか?

答え1

AUTOCREATE_SERVER_KEYSファイルでは無効/etc/ssh/sshd_configですが、/etc/sysconfig/sshd

答え2

AUTOCREATE_SERVER_KEYS=RSAONLYサービス設定の一部で/etc/sysconfig/sshdあり、sshd構成の一部ではありません。/etc/ssh/sshd_config
