snort on multiple interfaces

2009-10-28 Thread Andrea Venturoli
Some years ago, I checked to see whether I would be able to let a single 
snort process listen on more than one NIC.

At the time it was only possible in Linux.

Now, I searched a bit, but nothing new came up.

Did anything improve since then? Do we still need multiple snort 
processes to listen on more than one interface?

Can some netgraph node help with this?

 bye & Thanks
av.

Hi. Regarding "automatic vlan creation"

2009-10-28 Thread Sebastian Hyrwall

Hi

Now that FreeBSD has support for writing  , cloned_interfaces="em0.100" 
instead of having to create for example a vlan0 and then specify vlandev 
etc in ifconfig. What is the correct ifconfig-line in rc.conf for this?


ifconfig_em0.100="" or ifconfig_em0_100="" does not work.

Sincerely,
Sebastian H

  In Linux the packet capture facility is implemented in a different
(and very inefficient manner), via raw sockets (which means that, in
order to reach userspace, a packet has to travel the whole IP stack -
including firewall - until delivery to the user process). BSD has BPF,
which basically delivers a copy of the packet to the userspace right
before it enters the IP stack for kernel processing. Each network
driver does this through the BPF_TAP() macro.

  You can try lagg(4) with the "loadbalance" option, ng_one2many(4),
or ng_fec(4).

You can do this using if_bridge in monitor mode like so:

{/etc/rc.conf}
## DMZ Span Port
cloned_interfaces="bridge0"
ifconfig_fxp0="up promisc"
ifconfig_fxp1="up promisc"
ifconfig_bridge0="addm fxp0 addm fxp1 monitor up"

And then have you snort process run on bridge0.

You probably forgot to put if_vlan_load="YES" in /boot/loader.conf
ifconfig_em0_100="..." should work.

PF and DHCP

2009-10-28 Thread Jonathan Belson

Hiya

I have a server which acts as a gateway between the internet and my  
internal network.  The external interface receives its IP address via  
DHCP.  I set up pf.conf to allow DHCP packets via ports 67/68, but I  
notice that when the server boots, the DHCP exchange happens /before/  
PF gets started.


Does this mean that adding rules for DHCP isn't necessary (my firewall  
rules are block in/pass out, with a bit of NAT thrown in)?


Does this mean that when my machine boots, there's a window between  
the interfaces coming up and the firewall being enabled?


Thanks,

--Jon

To address just this question, it is a good idea to leave the rules that 
allow DHCP in there, as the DHCP client will need to renew its lease 
later, while the firewall is running.

You can safely use /etc/exports without touching sharenfs property.

Yes, that release does include a good version of BCM5709 bootcode (v5.06).
I couldn't really tell until I downloaded the file and looked at the 
temporary files inside.  Thanks for the link.





After fighting with the update process for a bit and then learning about

On the face of it, it seems that this resolves the issue.

Sorry but my reation is: eww.  There's no way I'd commit that.  You'd be
randomly loading the vlan code for any interface that had a dot in it.

The real change we should make it to add device vlan to GENERIC.  It's
long past time for it to be in by default.

RE: kern/139145: IPv6 blackhole / reject routes broken

2009-10-28 Thread Li, Qing
I remember looking at this bug and tried to reproduce it ...

If my memory serves me right, I believe this bug was fixed by 
svn r197364, committed on 9/20.  RC1 was built on 9/17.

Another symptom of this bug is the "route get" command issued 
on any lo0 addresses returns "destination: default" instead 
of "destination: lo0".
