where is tunctl
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Is this howto out of date?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

Install tunctl on CetnOS 7 ?
EPEL doesn't have uml_utilities and NUX doesn't have tunctl.

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.

controlling VM access to different tap devices
...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/...

[Bridge] Bridging between user processes
...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

bridge network question
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.

Tinc on Linux and tap device problem
...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...

Virtual Interface
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.

Virtual Bridge & Shorewall Question
...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

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,

Using tinc on planetlab
...some problems using the tap device
tincd just keeps printing this error:
Error while reading from Linux ethertap device /dev/net/tun: File
descriptor in bad state
I guess the problem is I cannot manage tun/tap devices on the planet
lab nodes even if I am root :(
Look at this:
bash-3.2# /usr/sbin/tunctl
TUNSETIFF: Operation not permitted
bash-3.2# whoami
root
bash-3.2#
I know this is more a planetlab problem than I tinc problem and I am
offtopic, but I am really looking for some hints, so if anybody can
help me please write me an email even privately.
thanks

You can create it with tunctl.

ipconfig problem if multiple devices are up
...are up and
connected to the same network. It seems that it uses the wrong
socket/device index to compare it to incoming packet. To be more
precise, the packet gets discarded in do_pkt_recv as the ifindex from
state differs always from the incoming packet
To reproduce create two tap devices:
$ sudo tunctl -u uli -t tap0
Set 'tap0' persistent and owned by uid 1000
$ sudo tunctl -u uli -t tap1
Set 'tap1' persistent and owned by uid 1000

How does the libvirt deal with the vnet mac address
...et0 device in the hypervisor and the ethX device in the VM, for example :
the mac address of vnet0 is FE:54:00:84:E3:62
the mac address of ethX in the VM is 52:54:00:84:E3:62
two mac addresses above are almost the same except the first part of the address .
but if I created a tap device manually ,
tunctl -t tap0 -u root
brctl addif br0 tap0
and add tap0 to the VM, I will find that mac address between the tap0 device in the hypervisor and the ethX device in the VM will totally different . so I think that libvirt must do something about the mac address handling, could you please kindly tell me someth...

Tinc sudden spike in traffic usage
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.
