转换 syslog-ng 3.0？格式为3.2格式

刚刚重新启动我的系统时出现此警告

:: Starting Syslog-NG                                                                       [BUSY]
WARNING: Configuration file format is too old, please update it to use the 3.2 format as some constructs might operate inefficiently;
WARNING: the expected message format is being changed for unix-domain transports to improve syslogd compatibity with syslog-ng 3.2. If you are using custom applications which bypass the syslog() API, you might need the 'expect-hostname' flag to get the old behaviour back;

有人知道有关转换格式的任何好资源吗？我的syslog-ng.conf主要来自Gentoo 安全手册因此仅仅使用该文件.pacnew是行不通的

这是我当前的conf文件

答案1

它可能与 3.2 中的此更改有关：

  • 即使在本地传输（例如/dev/log）上接收到系统日志消息，syslog-ng 传统上也需要一个可选的主机名字段。然而，目前还没有 UNIX 版本包含此字段。当创建日志消息的应用程序的程序名称字段中有空格时，这会导致问题。如果配置版本为 3.2，则 unix-stream/unix-dgram/pipe 驱动程序的此行为已更改，并且可以通过使用特定源的显式“expect-hostname”标志来恢复。

您收到警告是因为您使用了 unix-stream("/dev/log");在你的来源中。如果您的本地日志没有遇到任何问题，除了将第一行更改为 @version: 3.2 之外，无需执行任何其他操作

如果您的发行版将主机名添加到来自 /dev/log 的日志消息中（很少这样做），那么请在源代码中包含 flags(expect-hostname)。
