I'm dropping all ICMP type 8 packets on the INPUT chain and so now I'm seeing log entries as a Fabric script tries to contact another server, like this:
kernel: INPUT DROP IN=eth0 OUT= SRC=<ip1> DST=<ip2> LEN=88 TOS=0x00 PREC=0xC0 TTL=50 ID=60964 PROTO=ICMP TYPE=3 CODE=3 [SRC=<ip2> DST=<ip1> LEN=60 TOS=0x00 PREC=0x00 TTL=49 ID=45897 DF PROTO=TCP SPT=34120 DPT=22022 WINDOW=14600 RES=0x00 SYN URGP=0 ]
However they're different to the tcp/udp log entries I'm used to, specifically the section in square braces. What do it's different parts relate to?
