之前就一直想從http的log裡找出一些不正常的網路行為
但實行上有點麻煩
要麼就要在每台上去解析log再把資料收回來處理
要麼就是在每台 web server 設定把log丟到一台log server 再來處理這些log
但以上都會碰到相同的問題
就是log格式都不同
處理起來相當不方便
bro ids 解決了這個問題
因為她把http的訊息存成 http.log
由於是port mirror的資料
所以不用管是用什麼web server 沒有格式的問題
以下是收到的部分相關log

除了偽裝成不同OS跟不同browser之外

再來就是一直try各種預設管理軟体的路徑及檔案

封包丟過來不一定會等回應

所以不一定會有 404 的回應碼

可以用搜尋關鍵字的方式

找出有問題的 ip 來處理

2018/12/26

proxmox中如果guest的vm file是放在local disk
從web介面是沒有辦法online live migration的

會出現

2018-12-26 12:52:46 starting migration of VM 701 to node 'proxmox2'
2018-12-26 12:52:47 found local disk 'local-zfs:vm-701-disk-0' (in current VM config)
2018-12-26 12:52:47 can't migrate local disk 'local-zfs:vm-701-disk-0': can't live migrate attached local disks without with-local-disks option
2018-12-26 12:52:47 ERROR: Failed to sync data - can't migrate VM - check log
2018-12-26 12:52:47 aborting phase 1 - cleanup resources
2018-12-26 12:52:47 ERROR: migration aborted (duration 00:00:01): Failed to sync data - can't migrate VM - check log
TASK ERROR: migration aborted

要手動下指令

qm migrate vmid nodename --with-local-disks --online

例如
qm migrate 701 proxmox2 --with-local-disks --online

前不久才寫過安裝bro ids 的文章
最近 2018/11/29 更新版 2.6

今天測試安裝完成
記錄一下過程

make 的時間比之上一版更久了

先修改

/usr/local/bro/etc/node.cfg
interface=eth1 (監聽的mirror port)

make install後先使用 broctl 進行 start 發現無法啟動

先安裝sendmail
yum -y install sendmail

再來有二個檔案要修改

/usr/local/bro/share/bro/broctl/standalone.bro

#@load standalone-layout

/usr/local/bro/share/bro/broctl/auto.bro

#@load local-networks
#@load broctl-config

改完後啟動就沒問題了

接下來在 /etc/rc.local加入

/sbin/ifconfig eth1 promisc
/usr/local/bro/bin/broctl start

然後log的預設路徑變了

/usr/local/bro/spool/bro

接下來就可以把所需的log吐出去了

vi /etc/rsyslog.d/bro.conf

input(type="imfile"
File="/usr/local/bro/spool/bro/sip.log"
Tag="bro_sip:"
Severity="debug"
Facility="user"
)

user.debug @2.3.4.5:514

Sverity 使用 debug 才不會寫到 /var/log/messages
