iptables starts blocking outbound http traffic
Hello:
I have a machine running CentOS 5 x86_64.
It is running apache httpd and tomcat.
For some reason, after running for a few days,
web requests stop responding. It happened again
this morning. I check the syslog and see a HUGE
number of logs like this:
OUTPUT IN= OUT=eth0 SRC=[MyIP] DST=[OutsideIP] LEN=532 TOS=0x00 PREC=0x00
TTL=64 ID=52669 DF PROTO=TCP SPT=80 DPT=54697 WINDOW=61

Error messages? or what
I've been seeing this kind of crap now for some time, and only in the
past couple of weeks did I realize I was using the Plus Kernel instead
of the normal stock kernel. Could this have something to do with it?
Messages also appear mentioning something about a PowerNow K-8, which I
thought was something you'd see from an AMD processor, not a quad core
intel 64 bit box. Any insight

Completely isolating P2P/BitTorrent traffic
Hi all,
I''m tring to isolate P2P traffic, specifically BitTorrent, for my QoS
scripts. I can''t seem to completely isolate ALL BitTorrent traffic.
I identify & mark packets and then use tc filters to put them into
appropriate classes. My firewall rules (below) do the markings. My VoIP
boxes'' and ICMP traffic get highest priority (mark 1). Then comes DNS, SSH,

[CENTOS ]IPTABLES - How Secure & Best Practice
Ned,
Thank you very much for the response.
Great example following through on the premise.
It sounds like I need to have a better understanding of the traffic
patterns on my network to know the optimal order for iptables
filtering rules.
My brief example -
Premise: I want to limit outsiders from interfering with LAN client machines.
So, I have the following rules regarding forwarding traffic:

Shorewall help blacklist and restart/refresh
At the current time I am not subscribed to the mailing list.
I have a blacklist that I got from www.peerguardian.net that is rather
large ( 81 kb).

Also I noticed something very strange with shorewall ..

Fixing to bite the dust?
I've been getting LOTS of messages like the below in the daily log, and
from all indications, it appears to all be related to the cpu;
the machine is just over a year old, and was the old vortex.wa4phy;net
server from the downtown co-lo site. Aside from huge log files, and
lots of other fluff, numerous problems of other nature have started
cropping up. Anyone have any suggestions as to

Dev: new option to mark all tincd socket of a tincd process
I know i'm new to the list but i'd like to propose something for tincd
daemon.
I'd like to mark all sockets established by a tincd process with a mark
passed as an argument in the command line.
What could be the purpose of this new option?
The goal of this option is to be able to have several tincd process
running at the same time using the same port but using different ip.

samba with iptables
Hi,
system info:
ubuntu 7.04 (Host OS)
samba 3.0.24 (installed with apt-get)
vmware-server 6.0.1

I was using the iptables script provided by iptablesrocks.org. It's been
quite useful, but I ran into a problem when I tried to connect samba.
Without any iptables rules, I have no problem when connecting host
os(ubuntu samba server) from guest os Windows XP.

Bind data directory borked on update from 5.3 to 5.4
I updated my secondary DNS server from 5.3 to 5.4 today. After the
update, named would not start. A bit of investigation found that all of
the files in /var/named/chroot/var/named/data had been turned into links
to themselves!
Fortunately, since this is a secondary DNS, all I had to do was delete
the files, replace the root hints file and let everything else copy back
over from the master. If

minor tick marks
Hi !
I need a plot for data extending over several orders of magnitude on the y axis.
The following command generates a nice looking semi-log plot for my data:

I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

Server hangs initializing audio
I have a server that frequently hangs while rebooting. I see no
errors, but during the boot process it stops at this stage:
Initializing hardware... storage network audio
The cursor sits just after the word "audio" and I have to do a hard
reset to get out of it. This server has no audio capabilities, so I
am thinking that I just need to disable the audio stuff so it doesn't

Problem with routing decisions, and multihop
Hi!
I have many problems getting this thing to work. There''s a host with
two network interfaces, where there are two routers to Internet in two
separated networks. The host uses multihop routing for deciding to
which router send the packets... but the routing decision is wrong
made. Some packets with source address of one NIC, go to other
network.
I have a host with three NICs in it:
