Security_Pete's questions

我有一个 cisco ftd 发送带有 local3(19) 标记的日志，但是我仍然看到一些消息最终出现在我的 users.log 中，而不是我将它们配置为发送的位置。如果不加标签，他们会到哪里去？或者有没有办法验证他们被标记为“用户”或设施代码 1？我没有在我的 rsyslog.conf 中注释掉用户。（Debian wheezy，rsyslog v5）

我是一个linux新手。话虽如此，我需要一个 cronjob 在 48 小时后压缩一些 syslog 文件，以保持大小可控。这些文件当前位于 /syslog - 我添加用于处理卷的磁盘。我曾问过一个先前的问题来处理这个问题，但我在此之后并且 cronjob 没有运行。它应该在几个小时前运行。我相信这项工作将在每天 01:00:00 运行。这是我当前的 crontab。

root@mysyslogserver:/etc# more crontab
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
0 1 * * * /bin/gzip /syslog/*-$(/bin/date --date='2 days ago' +%F) 

我想知道格式是否让我感到困惑？

提前感谢您的帮助。

我是 Linux 和 rsyslog 的新手。我已经使用日志文件很多年了，但我从来不需要设置一个。此时，我有一些概念验证设备指向我的 Debain Linux 服务器。我有 syslog 消息进入并写入单个文件：/var/log/prd/fwlog 我只关心 3 种设备类型 - 交换机、路由器和防火墙。（所有 cisco）我的 rsyslog.conf 相当简单，我只修改了基本配置，注释掉了我不喜欢/不需要的东西？

剪掉注释掉的东西。

$ModLoad immark  # provides --MARK-- message capability    

$ModLoad imudp
$UDPServerRun 514

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

$WorkDirectory /var/spool/rsyslog

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

*.*          /var/log/prd/fwlog

最后我的问题！

1. 我想在带有名为“rslog-YYYY-MM-DD”的日期戳的日志中旋转和分离路由器和交换机，还将防火墙放入带有名为“fwlog-YYYY-MM-DD”的日期戳的日志中

2. 我想在 48 小时后压缩（gzip？）日志。

我需要在我的配置中添加什么？

我想我在 /etc/logrotate.d/rsyslog 中将目录和文件添加到了我的 rsyslog

/var/log/syslog
{
        rotate 7
        daily
        missingok
        notifempty
        delaycompress
        compress
        postrotate
                invoke-rc.d rsyslog rotate > /dev/null
        endscript
}

/var/log/prd/fwlog*
/var/log/prd/rslog*

{
        rotate 4
        weekly
        missingok
        notifempty
        compress
        delaycompress
        sharedscripts
        postrotate
                invoke-rc.d rsyslog rotate > /dev/null
        endscript
}
