catching DNAT''ed packet
Hi.
I have a Server''s network with some servers in it, all with
192.168.1.0/25 ips. There is also a router in that network with ip
192.168.1.1. This router also connected to a client''s network
10.10.0.0/16 with ip 10.10.100.1.
All services on each server are given their virtual address from one of
two virtual networks 192.168.1.128/28 and 192.168.1.144/28.
192.168.1.128/28 is

iptables -m dstlimit
Which kernel supports the iptables'' -m dstlimit?
Do I need a patch or something else to get it to work?
Is it too experimental?

NAT/MASQ with multiple external static IPs
Hello everyone,
really not sure if this is a LARTC question or not, but I have several
hundred users all MASQ''d behind a single static IP. Users are reporting
that certain websites are blacklisting that single static external IP
for various reasons.
What I would like to do is use several external IP''s and have a MASQ''d
user getting a random one each time.

?OT? Linux 2.6: bridge + routing firewall
Hi All!
I need to deploy a bridge firewall using linux kernel 2.6. I had success
using kernel 2.4 plus br-nf patch. But the configuration does not work with
kernel 2.6.
If the default policy for the iptables FORWARD chain is ACCEPT I have a
bridge. If iptables FORWARD chain is DROP I have an insulator (no packet
flows). Any hint?
I did some google search and in many places they say "kernel

Applying the same class to multiple interfaces
Hi All,
I''m trying to do some traffic shaping on an ethernet bridge. Currently,
I have the following setup working:
ifconfig eth0 down
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
brctl stp br0 off
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig br0 up
This creates a bridge consisting of eth0 and eth1. So far so good.

iptables rules disappearing!!!
Hi all.
I have got to see a strange thing. Some of my iptables'' rules are
disaprearing after several days!!!
I have many rules like:
# iptables -t mangle -A $MYCHAIN -s $SRC_IP -d $DST_IP -j MARK
--set-mark $MARK
for classifying traffic for shaping, total about 100 rules with
different 20 marks, and rules like
# iptables -A FORWARD -m mark --mark $MARK
for accounting shaping

nmcli: unwanted secondary ip-address
Dear Simon,
every second IP-address is unwanted. We restarted? eno4:
nmcli con down eno4; nmcli con up eno4
and the second address vanishes. Then after a few ours, the second ip
address reappears.
This is the config-file of eno2:

POP3 Proxy : user format not accepted
Hello,
I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy). All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part at domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'.
Here is my proxy table :

That's really interesting. Doesn't NetworkManager also store other
settings in a different location, not the ifcfg files? I think it does so

Okay, nothing to find here.
What about eno2, you also have two IP addresses there and even in the same
subnet, is this wanted or not? Can the second address of eno2 be found in
the ifcfg file?
Both eno2 and eno4 have "scope global secondary dynamic"

Difference in gnome between centos <> fedora
Hello,
I've on my home PC CentOS 6 and Fedora 13 on different disks. When I log
on the gnome enviroment at Fedora knows exactly which programm was started
at which desktop (for example: thunderbird on desktop 1, firefox on
desktop 2, nautilus on desktop 3, ..). The same procedure on Centos takes
all programs on the first desktop, so I must arrange the programs on the
right desktop.

Multihome load balancing - kernel vs netfilter
Hi,
I have searched the archives on the topic, and it seems that the list
gurus favor load balancing to be done in the kernel as opposed to other
means. I have been using a home-grown approach, which splits traffic
based on `-m statistic --mode random --probability X`, then CONNMARKs
the individual connections and the kernel happily routes them. I
understand that for > 2 links it will become

Calls Dropping
Hi,
I'm having a major problem with random calls dropping. After spending weeks trying to figure it out, i've finally spotted the issue but don't know how to resolve it.
I run a sip server that's hosted in a data centre. It has a public IP address with no nat involved. My provider also has a public ip with no nat involved.
The sip phones are in a remote office behind a nat
