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 I am running a Linux 2.2.18 kernel, and the following lines have been added to the /etc/modules.conf file:...

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 then looks like: 10.3.3.3 nexthop via 10.1.1.2 dev tap0 weight 1 nexthop via 10.2.2.3 dev tap1 weight 1 Pinging 10.3.3.3 caus...

...st you end up getting python-virtinst from c6 base repo: python-virtinst-0.600.0-24.el6.noarch and not from Xen4CentOS repo, because the version there is "older": 0.600.0-19. .. which means the centos/xen-specific patch in python-virtinst is "lost". (default to tap2 instead of tap1, to make blktap2 work out-of-the-box with virt-install and virt-manager when using file based images as disks for VMs). So.. who can build a new version of python-virtinst, with the blktap2 patch applied? -- Pasi

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, having

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,

...book I would like to be able to browse the local network, behind the vpn server, for shared resources (samba). That''s why I am trying to implement bridging on this VPN server. Problems arise when I try to set up bridging in cooperation with shorewall. Setting up the bridge br0 with tap0, tap1 and eth1, without shorewall works fine. using the "brctl show" command shows that the bridge is working with the right interfaces (tap0, tap1 and eth1). In this situation I can ping from the firewall machine to a local network pc and receive answer. From the local network pc, I can brow...
