use the two iptables command which i gave you

first will delete the earlier firewall rule

and second will create a new rule for apache

and check whether its working or not

or you can show the output of

Code:
#iptables -L

Can we delete all the rules from IPTABLES permanently?

I just want to allow pureftpd port, httpd port, + 8080, ssh port 1234 (eg)
I am already blocking all ssh access except my ip range using denyhosts

Pureftpd

Quote:
Response:530 Login authentication failed
Error: Critical error
Error: Could not connect to server
But I am sure the login is correct. TSL is enabled in pureftpd

But I am sure the login is correct. TSL is enabled in pureftpd
Are you sure to delete all rules because those rules might have been created by someone intentionally

you can use iptables -F to fulsh all rules

Code:
#iptables -F
to check use

Code:
#iptables -L
you can use
Code:
#service iptables stop
instead of deleting all rules

to check if your server is running properly or not

What do you mean by someone intentionally?
If CentOS 6's firewall is not creating any rule, then i don't think nobody has access than me to create rules.

I will again going to drop all the ports from iptables once it is clean.
So, I can enable pureftpd, httpd, and sshd

iptables -F -- is flush not temporary? If i restart, it will get all the rules, won't it?

you will get the rules, yes. You can edit the file /etc/sysconfig/iptables directly to change them or run "/etc/init.d/iptables save" to save the current state back to that file.

check your iptables

Code:
#vi /etc/sysconfig/iptables
it must contain all the rules


Code:
#iptables -F

#service iptables save

#service iptables restart

#vi /etc/sysconfig/iptables

The file is not there.

#iptables -F
#service iptables save
#service iptables restart
After this, I guess all the rules will be permanently deleted.

Quote:
iptables -P INPUT DROP
Quote:
iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT
Quote:
iptables -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT
Quote:
iptables -A INPUT -i eth0 -p tcp --dport 21 -j ACCEPT
Will it work out?

I am not very sure if that will work

you can give a try
or you can do as I said

No issues if there is no iptables in sysconfig

Code:
#iptables -F
#service iptables save

#service iptables restart
check whether you still see all the rules
Code:
#iptables -L
