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

linux-2.4.22 + bridge + traffic control by MAC.
Dear all, I am working on a linux box (2.4.22 kernel) which is used as a bridge. And I want to add traffic control rules on it by client''s MAC. Does anyone has such experience on how to do that?

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? -- Покотиленко Костик <casper@meteor.dp.ua>

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. Here is

?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. I now want to use tc to shape traffic

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

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.

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 :

While I''m in temporary retirement, I''ve decided spend a little time experimenting with new things and making some updates to the web site. The biggest result of this effort to date has been: http://shorewall.sf.net/Shorewall_Squid_Usage.html This outlines how to use Squid as a transparent proxy running on the firewall, in the DMZ or in the local network.

> Dear Simon, > > >> And can you diff the config of eno1 and eno4. > > # pwd > /etc/sysconfig/network-scripts 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
