Debian 9服务器在auth.log中没有sshd


9

在我的其中一台服务器Debian 9上,没有来自sshdin的输出/var/log/auth.log。实际上,如果我ag sshd在中进行操作/var/log,就不会出现。唯一的auth.logsystemd-logind。实际上,几乎所有的日志消息都来自systemd,这令人怀疑。只有少数零星的东西。

这是我的/etc/rsyslog.conf(减去评论)(应为默认值):

module(load="imuxsock") # provides support for local system logging
module(load="imklog")   # provides kernel logging support

$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

$FileOwner root
$FileGroup adm
$FileCreateMode 0640
$DirCreateMode 0755
$Umask 0022

$WorkDirectory /var/spool/rsyslog

$IncludeConfig /etc/rsyslog.d/*.conf

中没有任何内容/etc/rsyslog.d。我也尝试从Ubuntu 18.04计算机复制conf,但无济于事。

SSH是7.4p1-10+deb9u6/etc/ssh/sshd_config是:

# cat sshd_config |grep -v '^#'|sed -e '/^$/d'

我依稀记得,当这个问题开始,我确实看到了从一个非常偶然的消息sshdauth.log,但现在我不能证明正确。

显然,/dev/log是缺少的,这是systemd-journald-dev-log.socket.我必须systemctl restart systemd-journald.service修复的原因。

我现在无法重新启动以测试这是否是永久性的,但我现在就使用它。
