traffic shaping with two internal interfaces
Hi,
my shorewall is version 4.0.15 on Debian Lenny. I have 3 following
interfaces:
eth0 net (4mbit/512kbit)
eth1 loc (100mbit)
eth2 loc (100mbit)
I want to shape traffic from net on two lan interfaces like:
- default is 2000mbit for each local interface
- if is no traffic on eth1 is 4mbit for eth2 (and vice versa)
My tcdevices
eth0 4000mbit 512kbit

macro for dnat through alternate public ip (alias)
Hi,
I have a rule:
DNAT net dmz:a.b.c.d tcp 25 - k.l.m.n
The problem:
I want to DNAT port 25, 143, 110
k.l.m.n is alternate public ip (using vrrp, just like alias)
Can I abridge the above line using macro, instead of writing 3 separate lines?
I can do:
MailPorts/DNAT net dmz:a.b.c.d
But this refer to the physical public ip
I have more elaborate requirement to forward around 20

Combatting DDoS attack
Hi,
I''ve been working the past 8 hrs combatting DDoS attacks on websites and dedicated servers I host for clients.
They''re hitting one specific IP address, but coming from thousands of external IP addresses.
I use:
shorewall-4.0.10-3.noarch
How can I tackle this? I''ve blocked many subnets in the blacklist file but it''s made very little difference.

[Bridge] Multilink + bridge + nat problem
Hi, I have a suspicious problem with multiple uplinks configuration.
First of all my configuration:
1) kernel 2.6.20.3
2) iptables 1.3.7
3) last iproute (for masked marks)
All wan interfaces are bridged (stp disabled) in only one interface
(wan0), all lan interfaces are bridged (stp enabled) in only one interface
(zlan0).
The wan0 bridge is to allow UPnP works.

DomUs hidden behind Dom0 in the network?
Hello,
I am trying to set up a PVM (a the moment Ubuntu as guest and Ubuntu server as Dom0).
The main issue is that the DomUs can''t get direct net access, because the access is restricted by a DHCP server that also functions as proxy to the outside of the network. The server controls the MAC address and only http is allowed as outgoing connection. So the domUs shouldn''t appear

Hostap Shorewall and lld2l
None of my systems can use lld2d to map the network when connected via
wireless, but it works fine over the wireful network. the wireless is
client -> hostapd -> ath5k -> bridge -> kernel with shorewall handling
the bridge and kernel, as best I can explain it. on the bridge is also
a wired device and a bunch of other PCs. the wired PCs can all map
using lld2d just fine.

IMQ Stability
Hello all,
I have been doing a lot of archive searching over the last week reading
posts on IMQ and it''s apparent stability / instability. I have seen a
number of posts about it not being maintained as well. Can anyone talk to
me about IMQ''s stability in a heavy throughput environment (20 Mbps) and
what was causing IMQ to fail if you know.
Thanks,

Solaris 10 Jumpstart instructions on the wiki now
Not that I''m much of a Solaris guy, and definitely not a Solaris 10 guy,
but since nobody else had posted anything yet:
http://reductivelabs.com/trac/puppet/wiki/PuppetSolaris#Solaris10
The good news is that it appears to be a completely hands-off puppetd
installation. Just sign the client key afterwards on the puppetmaster
and you''re set. The bad news is that it''s

contrib/solaris/buildpkg.sh - use within JumpStart as well?
Hello,
I don't know how off the wall this question will be, but first let me
say that I've found your buildpkg.sh script very useful in creating
an OpenSSH package for use on my Solaris systems. Currently I'm trying
to set up a fully automated JumpStart system at my workplace, and I'm
realizing that the 'postinstall' script (and possibly some of the other
install scripts)

conntrack match failed, packets not FWMarked
Hi all,
I have 2 ISPs on a Linux router and a local network with one Linux server
and many windows.
The local network is masqueraded.
I want to give access to port 25 and 80 of my server from any incoming
request (i.e. from my 2 ISP). I have made a DNAT translation, witch work but
the outgoing answers are not routed correctly. Of course, the de-SNAT
process is done before the routing process. So

Anyone ever gotten Solaris to install from a CentOS PXE server?
I'm poking through Solaris documentation trying to figure out how to make
it installable via our PXE server and, as with many things Solaris, I'm
hitting walls of completely foreign procedures and setups.
Has anyone managed to do this before? I'm trying to set Solaris 11.3 up.

Get your SXCE on ZFS here!
With the release of the Nevada build 90 binaries, it is now possible to install SXCE directly onto a ZFS root filesystem, and also put ZFS swap onto a ZFS filesystem without worrying about having it deadlock. ZFS now also supports crash dumps!
To install SXCE to a ZFS root, simply use the text-based installer, after choosing "Solaris Express" from the boot menu on the DVD.

compressed root pool at installation time with flash archive predeployment script
I was trying to think of a way to set compression=on at the beginning of a

Thanks,

NOTICE: cannot instrument return of fd_intr at 7b7d6278: non-canonical return instruction
Folks;
During a jumpstart (2nd boot) of a Sun Fire 240 with Solaris 10 Update 3
(11/06), I noticed the following message;

Kernel level was Generic_118833-33. Jumpstart was conducted using the

What gives?
The jumpstart worked though. Solaris 10 installed
