4. How can the community help?
I am a newbie using Graylog, and would welcome a bit of assistance in extracting fields from the following messages
<129>Jun 13 06:34:34 DrayTek: [DOS][Block][Blocking List][188.8.131.52->255.255.255.255]
DrayTek: [DOS][Block][Blocking List][184.108.40.206->255.255.255.255]
The two IP address’s to be stored as new fields hackIp, ispIp for further analysis
<129>Jun 11 14:27:12 DrayTek: [DOS][Block][tcp_flag, scanner=non_syn_ack_rst][220.127.116.11:3197->255.255.255.255:80][TCP][HLen=20, TLen=89, Flag=P, Seq=3197, Ack=0, Win=65535]
The two ip address’s and the associated ports
I am using the wizard to try to create the extractor on the input from the draytek, and place the extracted data into new fields
hackIp, hackPort, ispIp ispPort for further analysis
PS 255.255.255.255 is not my isp address
