tap1 problem
Hi Tinc Mailing-Group,
Having set up the kernel correctly, and got tinc running successfully,
I am now trying to get two VPNs running at once. Hence I need to
have two ethertap devices ( /dev/tap0 and /dev/tap1 ).
The first tap0 device was created thus:
mknod -m 600 /dev/tap0 c 36 16
chown 0.0 /dev/tap0
The second tap1 device was created too:
mknod -m 600 /dev/tap1 c 36 17
chown 0.0 /dev/tap1

Problem
Hello.
I am trying to get multi paths running, i.e I want to specify 2 paths
from a particular node to another.
To test this, I am setting up the following scenario:
I create 2 tap devices
tap0 = 10.1.1.1/32 netmask 255.255.255.0
tap1 = 10.2.2.2/32 netmask 255.255.255.0
I then issue the route command:
ip route add 10.3.3.3/32 nexthop via 10.1.1.2 nexthop via 10.2.2.3
The route table

linux bridging problem: how to emulate 2 separate interfaces on a single one?
Hi all.
I would need to use a single physical interface on a Linux box to manage
two different IP addresses (belonging to two separate logical subnets)
with two different MAC address. (I need to emulate te presence of two
separate physical interfaceses for a PC on the same LAN, at layer 2 and
layer 3).
Is it possible to use the linux ethernet bridging code and two tap
interfaces for this

[PATCH net] vhost: net: switch to use data copy if pending DMAs exceed the limit
We used to stop the handling of tx when the number of pending DMAs
exceeds VHOST_MAX_PEND. This is used to reduce the memory occupation
of both host and guest. But it was too aggressive in some cases, since
any delay or blocking of a single packet may delay or block the guest
transmission. Consider the following setup:

Shorewall and OpenVPN woes
Ok. I''m knocking down one problem at a time.
I''ve managed to figure out how to bridge my tap0 and my eth1 with br0.
This is good stuff.
But if I have shorewall running, I can''t ping the local network at all.
If I have shorewall not running, I can ping the local network.
Here is my setup.

Shorewall/OpenVPN issue
Good day,
I have gone through a couple of the HOWTO''s on how to get this to work, but
I am still sitting with a very strange (for me) issue.
If two clients connect via OpenVPN (bridged), they can access each other
without any problems, but neither of them can access the server, nor any
system behind it.
I am fairly sure it is a Shorewall issue, but I am very new to Shorewall,

Network isolation - PCI passthrough question
Hello,
I thinking about using PCI passthrough to dedicated a domU as firewall.
I understand PCI passthrough concept. When done, my domU will see
network card and the dom0 won''t any more. So I''ll be able to filter all
trafic from outside, since it will go through network domU.
Then, how will I be able to connect other domU (and maybe dom0) to the
network domU ?
In a normal way,

bonding problem with arp-monitoring
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
