inquiry about differences between the tap and the vnet in the virt-manager Greetings! I encounter a problem about the network when using virt-manager to create and run a VM. when I want to establish a network bridge for the guest OS, I generally use two kinds of ways described as fellow : First method : create a bridge with the help of linux commad: brctl, or Second method : using

Hi All, I am facing an issue regarding communicating a value from outside to a Guest OS (linux, solaris and windows) launched on Xen Server. I did went through this thread, but It was not completely clear. http://lists.xensource.com/archives/html/xen-users/2006-07/msg00473.html My question is - Is there a way in Xen, through which I can communicate a value from outside to a Guest OS (linux,

Hi! I want to forward the port 3389 from the domU to the virtual server with ip address 192.168.122.77 with not success... I tried a lot of iptables rules with no luck so far. Is this possible? I take a look at other post and I don''t found an answer. By example: /sbin/iptables -t nat -A PREROUTING -p tcp -i xenbr0 --dport 3389 -j DNAT --to 192.168.122.77:3389 the virtual nic for the

Hello there, I was hoping that maybe one of you guys could help me out with a problem I'm experiencing with tinc1.0pre7. First, I'll start with my configuration, after that I'll explain my problem. Background ---------- This is a simple, client-server situation on a private network. Both machines run the same Debian Woody 3.0 testing installation and both have identical packages

Although we (the authors of tinc) have done our best to make tinc as secure as possible, an unfortunate combination of encryption and key exchange techniques has created a hole in at least all versions of tinc >= 0.3, including the current CVS version. Exploit: If somebody can intercept the meta protocol to a host that is running a tinc daemon, it is possible to decrypt the passphrase, which

Hi everyone! I have the following requirement: I need to connect a set of Docker containers to a KVM. The containers shall be isolated in a way that they cannot communicate to each other without going through the KVM, which will act as router/firewall. For this, I thought about the following simple setup (as opposed to a more complex one involving a bridge with vlan_filtering and a seperate VLAN

Well, I found a solution and posted it on the appdb's page of Red Alert 3. http://appdb.winehq.org/objectManager.php?sClass=version&iId=14371 Here's a copy of the informations I posted on the Red Alert's Appdb webpage : > Thanks to raphael, here's a mini "how to play on LAN to RA3 with Wine + windows users, when the LAN is a VPN" > > My hostname, in

I have a Debian 8 64-bit machine set up as a server and apt-got the tinc package. I configured tinc as a bridge and everything seems normal except that the tunnel does not forward multicast traffic. I used tcpdump to examine the br0, eth0 and tap interfaces. I could see multicast packets on both br0 and eth0, but there is no such packet present on the tap interface. I don't quite know why

I would like to track DomU bandwidth usage from Dom0 but my OpenSuse Xen install is not tracking DomU bandwidth correctly. My DomU guests are able to access the network and therefore the networking layer appears to be working correctly. It just doesn''t report the traffic correctly in ifconfig. I am currently running OpenSuse10.3 with Xen 3.1.0_15042-51.3 running a xen kernel

Hi list. I started with Xen yesterday, but I am facing a bit of a problem. My system had always configure eth0 with 10.0.0.4/8 I am using Xen unstable source (on Debian sid) Now I installed Xen, rebooted the machine, and first the usual network is coming up and then the xend will be started. I''ll end up with this, but I am wondering if this should be the way of things to be

Hi, we are using Tinc in our Freifunk Network in Oldenburg for internode connections over the internet. So Tinc is running on OpenWrt 10.03 on Dlink Dir-300 Routers. We all have enough internet bandwith (1,6 MB/sec and more) but we only get a maximum speed of ~350KB/sec between two tinc nodes because then tinc uses 99% of the cpu. Is it possible to get more Speed with tinc on this machines?

Hello. I need your help, DomU xen network diconnects randomly, how do you monitoring this? When I connect to vnc server in the hosts, DomU is running, then I open the DomU, after that guest network responds. DomU Debian 6.03 over Centos 5.7 and Xen 3.03. My network configuration: eth0 Link encap:Ethernet HWaddr 68:B5:99:78:AA:6D inet addr:192.168.5.230 Bcast:192.168.5.255

Hi Folks, This has been driving me nuts all day. I've been unable to google myself out of it. Maybe someone here can help? I followed the instructions from: http://www.tinc-vpn.org/examples/macbook-install/ Ubuntu server <-> Ubuntu server works just fine with the same config. Ubuntu server <-> Mac laptop not so much. The error I'm getting is: 2012-04-10 21:48:44

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the

Hello, I have been using the bridging facilities provided by Linux (vanilla 2.6.7 SMP with UML skas host patch applied) to bridge a regular physical ethernet network (on interface eth0) with a virtual network (on interface tap0, cf uml_switch, http://user-mode-linux.sourceforge.net/networking.html). A couple of virtual machines (run using user-mode linux, a tool that enables you to run linux

I have succeeded in getting two tinc1.0pre3 hosts to connect, but I can't ping one from the other. I can ping the local tap interfaces. tcpdump shows that icmp echo requests are received by the other host, but no replies are sent. The two hosts are North and South. It is the same pinging North to South and South to North. The hosts are configured as follows: South: Debian 2.2
