can't initialize iptables table `filter': iptables who? (do you need to insmod?)

Hi guys I am using centos 5
and when I try to make this to allow port 7777 to be open to access kloxo I get:


Code:
iptables -A INPUT -p tcp --dport 7777 -j ACCEPT
iptables v1.3.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

I am using a xen based yardvps which comes naked as sh..



i tried with this:


Here what I did to fix the problem:

Code:
yum install kernel-xen kernel-xen-devel
/sbin/depmod
After that, /sbin/iptables -L now works correctl

but does not do the job

any ideas

thx

You might have fixed this error. What is the result of "iptables -nL" now? And, there is no chance that 7777 is blocked ( in order to allow it ) as cento's iptables by default will ACCEPT all connections except ICMP.

thx mate . I will check tomorrow and let you know . My cell phone does not have putty and im in bed now.

Another thing that happened after installing kloxo is that i installed vsftp and it fails to start . I did a grep ftp and there was a pure ftp there ( i will be more precise tomorrow). Could the pureftp be the one causing the failure to start of the vsftp ?
Ive tried this in two boxes ( installing kloxo first and then vsftp and same errors showed up ) . I will paste what the tail command prompts out .

Thanks in advance

pure-ftp is already installed and running, so vsftp is not going to listen in FTP port. You do not require vsftp as pure-ftpd is already installed and running.

I guess, the kernel doesn't have netfilter module enabled. You might be running a custom compiled kernel?
