Hi Guys,
I'm facing some issues with Pfsense and a Carp setup where connections are
not dropped but the connection is not stable.
I have set macspoof on the vm that runs Pfsense, this because it needs it
for Carp.
My TCPdump actually give good results, a single P so that looks also well.
I have tested this with things like sending emails and so on, uploading
large files. It seems on sending emails that you most of the time have to
canceld a send and resend it, sending goes well than. A tcpdump on such
mailserver looks well.
For uploading large images it seems that it's slow in uploading because of
disconnects, also a good tcdump.
Do I need to make specific settings on the vswitch or the real switch
between ?
Or is something else going on ?
Cheers,
Matt
4:18 a.m.
This is resolved.
It seems that skews that pfsense sets on a backup/failover cluster node are
much higher than they were set manually. Pfsense synced them again and it's
solved.

Traffic issues are solved, but the advertising in not that well.
I see on ESXi (vSphere) that you need to enable "Promiscuous Mode", but how
on oVirt ?
http://www.blissfulidiot.com/2013/11/using-carp-with-vmware-esxi.html
Do I need the vdsm-hook-promisc for it ? as I need to make real settings on
a VM there I think the vswitch only needs the mode.
Information is welcome!

OK, also this is finetuned, but it would be nice to have some more info
about the hooks in these cases... it's interesting as oVirt has the right
settings to start with but we need to know what we need to set when we have
a setup like this for an example.

Well maybe begin yourself as a good example
and write down for the community / others
what you did to solve your problems?
I'm a little amazed you want to know from
others the settings needed but you don't
provide anything of your settings you already
tweaked to achieve your goal.
a good way to start would maybe
etherpad.ovirt.org and write some FAQ
for the most common use cases?
If no one else is willing to start
I will do it at some time (when I have some).
But this will most likely be in my spare
time, so don't expect too much. :)

Could you explain what you have done, and what do you need promiscuouity
for? oVirt has "port mirroring" that allows to mirror ip traffic from
one vm network to another.

Hi Guys,
I'm not able to write a howto yet as we need to check how this is running
on high traffic and we are going soon. Than, we need to test some other
functions before I can actually write something down.
Because this is not all documented well indeed I'm in testmode and doing
some @ life system as reallife environments are always coming with other
things than your prefec test.
I cannot say I needed promiscuouity, I did some things you would normally
do on pfsense which fixed that part. Some old message you really need to
discard instead of clicking it away was confusing this test.

you are not supposed to need the promiscious hook for sniffing/mirroring
- that's by now part of engine/vdsm (at vnic level in earlier versions,
and at network profile in later versions iirc)

Itamar,
On some testhost I'm updating now to 3.4(.x) I also need to install the
hook it seems... it's not there by default.
Any idea why you thought it should be ?

there is no need for the hook for port mirroring. you can define a vnic
profile with port mirroring via the engine and vdsm has this feature
built-in.
if you need more than just port mirroring (say, port forwarding), then
you still need the hook.

OK, now I'm confused.
For MacSpoofing we per default don't have the "macspoof" feature in the
engine am I right ?
To get that... you need to set:
engine-config -s EnableMACAntiSpoofingFilterRules=false --cver=3.X
But no hook needs to be installed for this ? I don't have ping at the
momment with macspoof set on true on a VM.

For MacSpoofing we per default don't have the "macspoof" feature in the
engine am I right ?
To get that... you need to set:
engine-config -s EnableMACAntiSpoofingFilterRules=false --cver=3.X
But no hook needs to be installed for this ? I don't have ping at the momment with
macspoof set on true on a VM.
macspoofing is more than just promiscuous mode for port mirroring, which
does require the hook to be installed (and the VM to be restarted)

there is no need for the hook for port mirroring. you can define a
vnic profile with port mirroring via the engine and vdsm has this
feature built-in.
if you need more than just port mirroring (say, port forwarding),
then you still need the hook.

you are not supposed to need the promiscious hook for

(at vnic

Could you explain what you have done, and what
do you
need promiscuouity
for? oVirt has "port mirroring" that allows to
mirror
ip traffic from
one vm network to another.

OK, we are on the same line there.
The issue is that it doesn't work on this host, others do.
I have a 3.3 cluster and 3.4... both are enabled using the command... or
can't you have 2 versions ?

Does the macspoof hook work fine on other host? And only here unknown

Hi,
I don't do top-postings, just a reply to all.
It works now on all hosts!
I was testing with a Run Once with no macspoof option and changed the CARP
IP on the pfsense box to alias, and back to carp... where with alias I was
able to ping with carp not... and this was good because of the disabled
macspoof option. After this change I was also, with spoof true and not set,
able to ping the IP on the CARP interface itself, so I think Pfsense messed
something up here with ARP tables (I know form the past).
After a restart of the VM I was able to ping all IP, also CARP as it was
starting with macspoof true again.
Some other thing I'm curious about... let's say you have 3 servers in a
cluster, 2 installed with the macspoof hook and one not. The VM with
macspoof enabled starts on the host without the hook and you migrate it to
a host where the hooks is installed. What happens... ?
Cheers,
Matt

When I answer to your question immediately after it, it's easier to
corrolate a question and an answer. Top-posting is frowned upon.
Once a domain xml has been created by Vdsm, it is migrated intact to the
destination, so there too, no filtering would take place.
Do note that having different installed on your cluster is bound to
cause random problem, and is better avoided.
