SINT - iptables usage notes (my edition)

My notes about iptables usage. This article will grow in time.


DROP incommig connections to TCP port 80 and insert it as rule 6 to INPUT table
 
iptables -I INPUT 6 -p tcp -m tcp --dport 80 -j DROP
 
DROP rule 6 from INPUT table
 
iptables -D 6
 
DROP outgoing TCP connections with given flags to destination port 1521 if there are more than 5 connections
 
iptables -A INPUT -p tcp -m tcp --dport 1521 --tcp-flags FIN,SYN,RST,ACK SYN -m connlimit --connlimit-above 5 --connlimit-mask 0 -j DROP

Some missing streams from 1st June '14

I'm sorry to tell you there are no stream dumps for Leporelo_FM and Signall_FM sessions live streamed at 01. June 2014 because of connectivity issues.

There is evidence this server was alive and properly working with established connections to the world.
Probably there was fault on the other side.

Please accept my apologies.
