解释系统日志中的后缀条目

这只是一个试图(但失败了)获取访问权限的机器人吗?有人能给我解释一下各个部分吗?和match_list_match位是怎么回事match_hostname

为什么这些日志会使系统日志混乱,而不是仅仅存在于专用的系统中mail.log

答案1

个人电脑来自印度失控并连接您的服务器。该机器人太愚蠢了,所以它试图对自己进行身份验证。不幸的是,您的服务器没有宣布 AUTH 功能,因此 postfix 抛出了错误503 5.5.1 Error: authentication not enabled。因此它断开与您的服务器的连接并转到下一个受害服务器。没什么可担心的。

对于有关 syslog 的第二个问题,OP 指出编辑的行

*.*;auth,authpriv.none;mail.none;mail.error -/var/log/syslog

将使/etc/rsyslog.d/50-default.conf日志转到 maillog 而不是 syslog。

答案2

除了 syslog 目标配置之外...您似乎已激活 Postfix 调试输出(使用debug_peer_list)。请帮自己一个忙并禁用它,然后您将获得 3-5 行日志,而不是每个连接 100 行。
