Ubuntu IPTABLE useful commands

List all rules
sudo iptables -L --line-numbers

Above command will list all rules with (num) in first column for each rule.

Now we can delete them by num
sudo iptables -D INPUT (num)

Super awesome example is here.

To block an IP 
sudo iptables -A INPUT -s xxx.xxx.xxx.xxx -j DROP

xxx.xxx.xxx.xxx is any IP address

mysqldump exclude some tables

if you want to exclude multiple table here is the simple command to do it

mysqldump -h yourHost -u dbUser -p dbName --ignore-table={dbName.table1,dbName.table2,dbName.table3,dbName.table4} > exportFile.sql

When I tried below command I was getting this error “Illegal use of option –ignore-table=.” . But the above command save my life.

 --ignore-table=dbName.table1 \
 --ignore-table=dbName.table2 \
 --ignore-table= dbName.table3 \
 > dbName.sql
