dovecot: auth-worker: order of authentication types
Hi all,
I'm setting a mailserver using dovecot version: 2.1.7. On the server I
have a couple of system users using PAM authentication and a lot of
virtual users using SQL authentication.
When a virtual user (e.g. david at virtdomain.de) logs in dovecot tries to
authenticate the user via PAM and after failing it uses SQL:

ingress and egress
ingress can be used to control the incoming packet,
such as:
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: protocol ip prio 5
u32 match ip src 172.16.1.11 police rate 10kbit burst
10k drop flowid :1

10k drop flowid :2

Libvirt "tc ingress qdisc" automatically removed by ovs vlan tag setting, how?
With outbound QoS setting in Libvirt XML, libvirt will add a tc
ingress qdisc for traffic shaping. Then if you set VLAN tag to that
tap device, this qdisc will automatically gone by no reason.
Could anyone shed some lights where should I look into? I'm really
confused and got no clue here. Thanks!

Multiple ISP + traffic shapping = poor download speed
Hello,
Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts.
First, what works.
Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze.
We have a 2 ISP:
- isp1 : an optical fiber provider with 10 Mbps.
- isp2 : a DSL provider with 15Mbits/1Mbits.
We use isp2 as the default outgoing

OpenVswitch with KVM virtual machines
Hey,
I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows:

virbr0 is the virtual network switch
VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively.

Discover what vnet is attached to a kvm guest
Hi all,
How can I see what vnet is attached to a certain kvm guest?? For
example: I have a kvmguest1. When I launch this guest with virsh
command, virsh creates a new vnetX interface for this guest. How can I
extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using
a script??
Thanks.

network intermitent, not sure if virtualization issue
I have a computer I am using to host a virtual machine.
Centos 6, for both, 64 bit.
The host machine's network connection seems fine. No problems.
Trying to access the virtual machine is usually fine.
but then, poof, ssh, http, ftp, all lose connection for about a minute.
Then they come back up.
I looked in all the logs on both machines, could find nothing, but not
sure where to look.

Need info on vnet mapping to guests
Hello:
I have a host running two KVM guests. The guests
use br0 and each has a static IP address.
I am trying to figure out if there is a way to
use snmpd on the host to measure the traffic
usage of the guests. I do not want to require
anything running on the guests since I do not
control them.
Looking at netstat -in on the host, I see this

Remove Virtual bridge and DNSMASQ
I am running KVM virtualization with libvirtd (libvirt) 0.10.2 in bridged
network mode, however I still have the default virtual network
bridge/interfaces and dnsmasq on the host. What I am trying to understand
is whether or not dnsmasq and the virtual network (*virbr0, Vnet0 and Vnet1*)
still play any role. If not, can I remove them?
On most virtual hosts I see they are left around even when a

Hi all,
Some background:
I recently has some issues with libvirt on my laptop when I got the error
'operation failed: pool 'default' already exists with uuid

Re: Remove Virtual bridge and DNSMASQ
HI Michal
Thank you for explaining. I have this situation in a number of production
servers where we would always use static IPs for the host and VMs. In such
case we have no requirement for NATed network in the future. And we we
ever do, we can rely on a DHCP server within the LAN to provide IPs to the
VMs.
I'll look to remove both libivirt-daemon-driver-network,

Hi list,
I searched the web for bug reports regarding this phenomenon I see on
