/etc/sysconfig/iptables on a stock CentOS 5 install
Greetings:
i have a pretty stock CentOS 5 machine with ports 80 and 22 exposed, so
my /etc/sysconfig/iptables file is pretty standard/straightforward.
my question is: how is this config file initially generated? i'd
like to
re-create it, and add a couple of rules .... so i don't want to lose
what's
in there already.
i see that my /etc/sysconfig/system-config-securitylevel has

Default Firewall Entries
Hello CentOS,
I'm curious... there seems to be a couple of default firewall rules
that I'm not familiar with in the CentOS 4.0
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter

:FORWARD ACCEPT [0:0]

kernel 2.6.21 on centos 5
I have a computer that I needed to put 2.6.21 on.
Everything is working fine after recompile except
when iptables is starting up it errors with
iptables-restore: line 23 failed.
This is the normal centos 5 iptables. nothing special.
What might I be missing in the new kernel that I get this error?
Thanks,
The file is below.

firewall question
My firewall config is below...
I am trying to figure out why another machine has access to port 5038 on
my machine
based on these firewall rules.
I thought the reject at the bottom would take care of all other ports?
It does not.
I have restarted with "server iptables restart" and same thing. I can
connect from another machine
to my machine on port 5038. How do I prevent this?

Networking problems with fresh install
I just did a fresh install of centos 5.0 from cd, followed by yum update
which installed 399 packages. No failures or errors that I can see.
I have three nics in the box, but am only setting up one at the moment.
The box can ping others in my network, but if I try ssh, telnet, ftp, etc
I get this:

Default CentOS(Redhat) iptables, Secure?
Hi All,
whilst not being an expert on iptables, the below ouput of iptables -L
seems too insecure to me. Does anyone agree.? Perhaps I'm not
understanding it as well as I think I am.? Please give your thoughts on
this. Cheers.
Mark Sargent.

vsftp passive mode / iptables issue
I've been struggling with my firewall and getting vsftp to work in
passive mode.
It seems that everything on this hosting server works just fine without
the eth0 entry in my iptables except for vsftp in passive. Am I opening
up too much by adding the eth0 line?

Samba4 and iptables
Hi everyone,
I had posted recently about getting Samba4 to work on CentOS 6.4 but
having changes only replicating in one direction, from the Win2k3 AD but
not back to it. I solved the problem, this time, by disabling iptables.
I find it a bit hard to understand. These are the rules I have set up:
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [52:5888]

Dear CentOS community,
