layer2 tunnel between guests across hosts
Hi,
Is it possible to setup layer2 tunnels between guests across hosts?
Using vrbr? -- i.e the Guest is unaware.
On Host 1:
guest (a) --- vrbr0 -------

On Host 2: |
guest(b) -- vrbr0 ------
Has there been any work done around it?
TIA,

Packet flow through IPFW+IPF+IPNAT ?
...On my FreeBSD 4.8 configured IPFW2+IPF+IPNAT and I use them all:
- IPFW - traffic accounting, shaping, balancing and filtering;
- IPFilter - policy routing;
- IPNAT - masquerading.
I want to know, how IP-packets flow through all of this components?
What's the path?
incoming: IPFW Layer2 -> IPFW&Dummynet -> IPNAT -> IPFilter ?
outgoing: IPFW Layer2 -> IPFW&Dummynet -> IPFilter -> IPNAT ?
Is this correct? Or IPNAT on the incoming packets run before IPFW L3:
incoming: IPFW Layer2 -> IPNAT -> IPFW&Dummynet -> IPFilter ?
I think this path is...

Cisco 7940/7960 QOS?
If I relay through my Cisco 7940/7960, does it do QOS, even with a dumb
switch?
I know you can set quality/qos but only if you have a layer2/layer3
switch that supports the tagging. A simple little linksys 5 port switch
wouldn't know about QOS, it'd give everybody equal priority. If a
computer plugged into the phone, and the phone into the dumb 5 port

filtering in layer 2 [but is not a bridge]
I have a linux AP with prism2 (hostap) wireless nic.
I whant to filter traffic that pass betwen clients of the AP, this is layer 2
traffic (802.11) and netfilter does not sees it, at first i think in physdev
target, but is for layer2 bridged interfaces, and this is not the case.
There is a way to filter layer2 traffic independet if it is from a bridged
iface or not?

can I check the mac address on DHCP from my command line
Hi,
I have an interesting problem. I want to be able to verify that my
hostname, ipaddress, and mac address are correct in the DNS/DHCP. I have
the values, how do I compare.
I am able to use NSLOOKUP for the hostname=ip confirmation
How do I do the ip addresss = mac address comparison
I tried arp and a few other things. Almost everything on google says

zaphfc 2 cards working with P2P Mode ?? - massive Problems

I need to make a cluster classification by the unique values of the data frame.

Does anybody know if the 3com NBX 100 phones will work with
Asterisk? The phones require a boot image to be sent either through

[Bug 969] New: Include L2 information in PCAP output
...correctly.
After a quick search, I found the following discussion on your mailing list :
http://marc.info/?l=netfilter&m=140625326302696&w=2
Since I did not find an opened ticket regarding this, I figured I'd create one.
"Another solution would be to add an options forcing the layer2 type for all
logged packets of given pcap output. This would allow to use kernel provided
layer2 information and write fully qualified packets for encapsulation like
Ethernet."
This solution would be enough for my needs !
Thanks.

Xen in a routed network environment?
Hello,
I''m used to using Xen in a bridge mode where my dom0 and all domUs
are on the same layer 2 network. However now I have to set up a
server whose eth0 is on one network and the domUs will be on another
/29.
So, for example, if the eth0 of dom0 is 192.168.1.214/24, then I
have 10.1.1.0/29 (10.1.1.0 -> 10.1.1.7) routed to it for use in
domUs, how would I go about setting that up?

"Mode Switch" and "Tunnelserver Yes" cause unnecessary traffic to clients (proposed patch)
...report, and a proposed patch.
Using latest stable tinc 1.0.12.
I have a central server and a few clients connecting to this server.
I don't want clients to speak directly, but I want all the
communications to pass by the server.
My configuration is:
Mode = switch
TunnelServer = Yes
I need layer2 because of some ethernet stuff on the clients.
When you have these two things set up it happens that the tincd damon
will ignore any Subnet add request, if not allowed in the
configuration file.
This means that, because tincd is working on L2, it will not learn the
MAC addresses of the other peers...

Ok, so I found a workaround for this, even if I do not know who caused
this issue.
Basically I noticed that I have this ssh connection issue only when
the ssh client runs on a windows host...
