This is a much delayed update to the iproute2 command set. It can be downloaded from: http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.18-061002.tar.gz Repository: git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git For more info on iproute2 see: http://linux-net.osdl.org/index.php/Iproute2 The version number includes the kernel version to denote what

I have a computer with two interfaces, say with addresses 192.168.1.1 and 192.168.1.2. I want to set up routing such that when I ping 192.168.1.1 it goes out through 192.168.1.2 and not to the local interface. Is this possible - all my attempts so far have been unsuccessful? If so, pointers, etc. would be gratefully appreciated. Jim -- Jim Redman (505) 662 5156 x85

Hi, I discover recently that the arp traffic is managed like any other flow. So you get hang after a moment if you don''t use a default class. Is the any means to avoid this ? Not to have a default class is a way to filter traffic ... One would be to managed to class ARP request with tc but I don''t know if it is possible. Thanks in advance, -- Éric Leblond courriel :

Hi all, I''m running Xen-3.2 and linux-image-2.6.18 as Dom0 kernel on a VT-x processor. The problem is that broadcast arp who-has packets are not seen in Dom0 kernel. I''ve tried both precompiled debian kernel and compiled latest one from sources as described at http://lists.xensource.com/archives/html/xen-users/2008-01/msg00699.html There is no linux bridge invoked,

Okay, so I''m trying to setup my multiple ISP setup that I described earlier. I have: # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP>

Hello, I use Julian Anastasov ''routes'' (to be more specific: static_routes, alt_routes and nf_reroute) patches on a 2.4.32 kernel. On the same host I run IPSec. I have discovered after a few hours of networking problems that, when IPSec is enabled on that patched kernel, inspecting packets with tcpdump while arping-ing a host from a network physically connected to this

Hello I have two linux machines connected via 2 dsl lines (bonded) 192.168.0.1-eth0-dsl---2Mbit---dsl-eth0-192.168.0.2 ^-eth1-dsl---2Mbit---dsl-eth1-^ so the final figure is something like this: 192.168.0.1-bond0---4Mbit---bond0-192.168.0.2 I can only use arp monitoring for fail checking - if one dsl line fails - automatically use only the other one. I set up everything correctly (i

Hi, The network topo looks like this: the original network: router1 router2 | | |----------------OSPF------------| the target network: (we need to insert a transparent firewall between these 2 routers, so a proxy arp is set up on firewall to bridge router1 and router2) router1 firewall router2 |

Hi, this is propably bridge related and not really a xen problem, but it might help someone: Some of our domUs are not able to arp. Arp -n show (incomplete), and doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out, the response comes in, but on the vifX.0 interface the arp response is gone. dom0# tcpdump -ni eth0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply

Dear Sir, Please help me in building the right solution. My requirement is: 1st I want to club both ISP bandwidth to get 512kbps. 2nd, In normal condition, it should be in Load balancing. 3rd , In ISP Failover condition, traffic will automatically route to working ISP. What I have: I have installed the RHEL 3.0 with 3 Network Card. Kernel is 2.4.21-9EL I have the link from two ISP both

I have question about multipath routing. I am running a 2.6.7 kernel (gentoo). I have a route with three nexthops on the same interface. I see a different nexthop being picked for different destination addresses. All is fine. Now if one of the nexthop goes down (arp entry times out and arp request doesnt get a response), does it remove the nexthop from contention and only use the remaining two

I''m working with LEAF boxes as gateway machines. I''m trying to implement Proxy-ARP to build a bandwidth manager for my network. I''ve gone as per the lartc howto to implement a transparent bridge in an existing network and plan to put in my tc script after this. I''m configuring the box as a standalone one before plugging it into the network. I''m getting

Hello everybody. I could not find an answer to my problem in the archive. (But that may just be me :-) ) I have a problem with proxy arp and connection from loc (localnet) and from the firewall. Works fine from internet to dmz / proxy arp and vise versa. I have a feeling the solution is simple, but I''m no guru in Linux routing etc. The problem seems to be the routing setup. loc -

I''m sure that I had found (and printed out ...) a really good tutorial that explain how to use Julian Anastasov''s routing patch, but I can''t seem to find it now.

Shorewall 4.5.1.1 I have 5 interfaces on a centos box, the first two are internal on two different subnets, the next two are two different ISP''s and the last one is a private network for testing and administration. The second internal subnet (eth1) is rejecting all the arp requests to it and I get the following in the log files ever second or two - May 16 05:28:54 services kernel:

Hi all, Does any one know if this is normal operating of ARP. Or where to start looking. I am seeing a lot of ARP requests for my router IP from the same IP within seconds. 21:04:41.112929 arp who-has IP tell MY ROUTERS IP 21:04:41.186354 arp who-has IP tell MY ROUTERS IP 21:04:41.372972 arp who-has IP tell MY ROUTERS IP 21:04:41.546921 arp who-has IP tell MY ROUTERS IP

Hi all. I experienced a strange behaviour in the "arp" command when I use the "pub" (publishing) flag. This is the scenario (I know it''s an unusual one, but it''s just for a test): __________ | | | host C | | | |__________| | __________|________________________________

I must have something configured wrong somewhere. I''ve enabled proxy-arp on my shorewall 2.0.7 firewall. Works fine for what its supposed to do, I can see all the machines through it great. However, whenever its enabled, the network on the DMZ goes screwy. I''ve narrowed it down to this: when proxy arp is enabled for that interface, like such: echo 1 >

I''m attempting to put together a Xen box, which has multiple VLANs running into it, on one bridged interface. I mostly copied the way it was done here: http://renial.net/weblog/2007/02/27/xen-vlan/ I basically have: bond0 is the bond device (composed of eth0 and eth1), vlan757 is the vlan device for vlan 757 on bond0, and "xen757" is a bridge created by the above scripts,

Hello I'm trying to setup a bridged guest on an ubuntu 13.10 but it doesn't work. (Everything is ok with NAT) Network sniffing shows that arp replies don't come back to the guest. Test 1 ------ Guest : ping host_bridge_ip (ok) Test 2 ------ Guest: ping other_lan_host (KO) other_lan_host - receives arp who-is request - sends arp reply
