Hello all, My question: - - - - - - - Does anybody know when the reverse path filtering occurs as the packet traverses the kernel? Does it happen before NF_IP_PRE_ROUTING (PREROUTING) or not? Does it only happen at route selection time? What I have tried to do to find the answer: - - - - - - - - - - - - - - - - - - - - - - I find a posting (from many years ago) [0], which suggests that this

I have a theory on the cause of a problem but it is still only a theory. I wonder if anyone here can confirm. I have a multi-isp configuration with a multi-path default route to each ISP, equally weighted. I am seeing, periodically, traffic dropped due to martian detection and errors logged on inbound traffic, but at other times, that same exact traffic will be allowed, no errors. My

Hi, I have two connections to the Internet. I implemented the load balancing as described in chapter 4.2 "Routing for multiple uplinks/providers" The problem that occurred is that the client applications like Yahoo Messenger or even PuTTY (SSH client) are loosing the connection very often. Does anyone experienced this problem? Does anyone knows an workaround for this problem?

Hi, I have three linux machines, and I want to let one of them forward packets betwen the other two. The forwarding node has two ethernet cards, connecting the two two machines respectively. However, when I ping between the two end points, the forwarding node can receive the ping requests at its eth0, but it never forwards them to its eth1. So is the reverse direction. The forwarding node is

Hello, LARTC mailing readers, I hope u can help with this mysterious issue i''m having with my linux box acting as a router.

Woops - my fat fingers hit the send key before I could put in a subject a minute ago. Hello - I am using kernel 2.4.27 and running into behavior I don''t know how to explain. I have 2 relevant interfaces. eth0 is external, eth1 is internal. My internal LAN is 10.10.10.0/24. My External range is 1.2.3.0/27 (dummied up). I have an H.323 videoconference device inside my internal

I''am using the following script to aggregate the bandwidth of one quad gigabit ethernet controller (pci-express). #!/bin/bash sysctl -w net.ipv4.tcp_reordering = 30 ifconfig eth1 up ifconfig eth2 up ifconfig eth3 up ifconfig eth4 up modprobe sch_teql tc qdisc add dev eth1 root teql0 tc qdisc add dev eth2 root teql0 tc qdisc del dev eth3 root teql0 tc qdisc del dev eth4 root teql0 ip link

Thanks in advance! Summary: when I load netem and teql together, teql doesn''t work correctly. (If I load teql only, everything is fine) I loaded both netem and teql. Netem is associated with eth0, and teql is associated with both eth0 and eth1. But traffic only goes out of eth1. Attached are the commands that I used to configure teql and netem (on machine 1), and commands to

First of all, thank you to all of you who have helped to make iptables possible, whether in writing the code for it or testing it. It is BETTER than sliced bread! :-) Anyways, I have two questions related to the use of iptables. 1. I read on a post somewhere that it is smart to put the following two rules at the end of one''s iptables ruleset: iptables -A INPUT -p tcp -i eth0 -j

Hello, I''m following this HOWTO http://linux-ip.net/html/adv-multi-internet.html to route outgoing SSH from a secondary ISP. I can see using tcpdump,jnettop,iftop that when one of the computers located in my internal network is trying to SSH to a box online using SSH, packets are routed via the secondary internet ethernet card. However, packets don''t seem to know how to get back.

Hi all iam using Iptables+TC+HTB on Redhat 9 working fine with the bandwidth control I am taging my eth1 with Vlan interface with Cisco Switch when even though i have mention ceil, its crossing more than Ceil, when they are effected Virus in their network or DoS attacks, its should be control the mentioned Ceil right, why this uploads are increaing.. when the uploads are increased all the

Can anyone tell me whether I have a routing problem, or an openVPN problem, or something else? I''ve stared at this for so long I think I must be looking in the wrong place! I have 3 machines: Machine A has single ethernet card, eth0, 192.168.5.5 Machine B has eth0, 192.168.5.? on the local net, eth1, 81.2.x.y to the internet, and

Hi. I´m making an script for load balancing of two cablemodems internet connections toward my LAN. The problem is that when I try to ''equalize'' the the two internet connections with the weight=1 it doesn´t work. On the other hand, if I put 5 and 5 it works, but not at 100%, it does intermittlently, some times works and others don´t. example: ip route add default equalize\

Configuration: (2) Dual Core Opterons 8GB RAM Apache used to balance 40 mongrel instances We receive Application 500 Errors. Nothing suspect appears in the log, so we are at a lost as to what to do next. Any advice would be welcome and/or an explanation of what types of things cause Application 500 Errors in mongrel.

Hello, I have a pretty standard two-interface setup with masquerading, so the local network can connect through the firewall to the Internet. On the firewall box (trevor), eth0 is connected to a cable modem and eth1 is connected to the local network via a crossed cable. There is one other machine on the local network (brian), whose eth0 is at the other end of the crossed cable. I used to have
