iptables rules

[real time]

Hi All , 

Anyone have knowledge on iptables rules in  RHEL?

I want to "allow ssh service only for specific users" , how can i write the rules?

I did the following thing , but it is not working. I tried many other combinations but it's not working.

Regards,

Hi , 

found the solution , same rule i have to apply for input traffic without mentioning owner field , since incoming packet will not know your HOST credentials.

THanks
