我遇到了一个问题,因为 ssh 登录和其他信息没有记录在/var/log/*
(尤其是auth.log
)
我已经在这里和那里阅读了所有的问题,但是配置似乎很好,权限设置正确,并且我正在与我的其他服务器进行交叉检查并且配置是相同的。
注意:为了访问机器,我必须通过 ssh 连接到主机,然后根据端口进行转发:例如ssh root@myserver -p 221
。myserver 有配置将 221 转发到serverwithproblem:22
。对于另一台服务器,我仍然可以看到日志,所以不可能是那样。
基本上,我不知道发生了什么。
这里是rsync.conf

设置为:

设置为root:adm
。知道问题出在哪里吗?
答案1
经过一番挖掘,我发现 init 脚本会检查以下文件/etc/default/rsyslog
我的设置为这个
# Options for rsyslogd
# -x disables DNS lookups for remote messages
# See rsyslogd(8) for more details
RSYSLOGD_OPTIONS=""
通过评论(在开头RSYSLOGD_OPTIONS=""
添加)它又开始正常工作了!#
答案2
我放弃调试它,实际上在我看来,rsyslogd 从命令行启动时工作正常,但不能正常工作(跳过日志,从不记录身份验证和用户日志等)。
我确保权限没有问题,调试了 2 个小时,没有发现任何问题,除了活动比应该显示的少(当不是从命令行启动时)。
apt-get remove rsyslog
apt-get install syslog-ng
这将使用 syslog-ng 替换有缺陷的 rsyslog,这是一个非常接近的替代品
