I am following directions in http://wiki.centos.org/HowTos/KVM#head-c02a0b33e7949b0bc3b151ac6e0bdfb91b6bbd1c it says do yum install bridge-utils - works fine, they yum install tunctl does not find anything. yum provides "*/tunctl" does not find anything I am using 5.4 x86_64. Is this howto out of date? How do I get tunctl? Thanks, Jerry

EPEL doesn't have uml_utilities and NUX doesn't have tunctl.

Which repo has tunctl for CentOS 7 ?

It looks like uml_utilities, which is where it is in CentOS6 EPEL and Fedora, isn?t built on CentOS7?s EPEL. It looks like the Nux repo has a ?tunctl? package though. -- Jonathan Billings <billings at negate.org>

...t appears to have vanished. I thought this community might have some insight. I am interested in controlling VM access to different tap devices so I want to have different qemu processes bound to different tun devices. I've created new tun devices (eg. /dev/net/tun_low) followed by the use of tunctl to create new tap devices based off of the new device nodes (ie tunctl -t tap0 -f /dev/net/tun_low). This also did not seem to work as the VM's seemed to still be accessing /dev/net/tun (running strace on qemu-spice I found it was still doing an open on /dev/net/tun) and not my new device /dev/...

...k to each other when they run on two machines connected over Ethernet. I would like to be able to test them on a single machine without employing the physical network. Would TAP + bridging do the job? If so, what am I doing wrong? Linux 2.4.20, root user. I set up tap interfaces like this: >tunctl tap4 >ifconfig tap4 4.4.4.4 promisc up >tunctl tap5 >ifconfig tap5 5.5.5.5 promisc up I then set up the bridge and add the tap interfaces to it: >brctl addbr tapbr >brctl setfd tapbr 0 >brctl sethello tapbr 0 >brctl stp tapbr off >ifconfig tapbr 7.7.7.7 netmask 25...

I have centos 64 6.5 I installed bridge-utils I installed tunctl I added BRIDGE=br0 to ifcfg-eth0 I created ifcfg-br0 with correct settings I did service network restart and I get an error about br0 not present. When I plug in the second network (USB to ethernet) It detects as eth1 What do I need to change to get this to work. Thanks, jerry

...se I need to run the OLSR routing protocol on the tunnel and if I use the tun mode OLSR will just skip the interface. (It is a well known thing, I had this issue before also when using OpenVPN in the past). The problem is that I cannot make tinc use a tap device. I created the tap0 interface with tunctl, however I have no tap0 characted device in /dev So in my tinc.conf a directive like: Device = /dev/tap0 makes no sense. If I don't give anyconfiguration tinc uses /dev/net/tun and sets up the VPN in tun mode without problems. DeviceType directive seems to be ignored on my Linux system (and...

Hi Guys, I want to create multiple virtual interfaces on a system running linux 2.6. The main requirment being, to assign unique MAC address fo each of the virtual interfaces. I need to know, if this is possible and will really appriciate if someone can provide me pointer in this direction. Thanks a lot. R.

...und on net. The questions are (based on the http://www.shorewall.net/bridge.html): 1) What should be included in /etc/shorewall/interfaces and /etc/shorewall/hosts - "br0" or "qtap0", "qtap1", etc? 2) Why the author of this script used "$USERID" in "tunctl -b -u $USERID -t qtap$i"? If the user is non-root, may it somehow affect Shorewall bridging setup? ------------------------------ # id of the user running qemu (kvm) USERID=1000 # number of TUN/TAP devices to setup NUM_OF_DEVICES=5 case $1 in         start)                 modprobe tun  ...

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,

I just encountered a weird issue on my servers - Tinc was using a constant 10-50% CPU on several servers, and these servers were also receiving a constant ~3 Mb/s of data over the Tinc interface, which is usually otherwise pretty quiet.
