gateway failover with linux
Hi.
I''m wondering if there''s a good way to configure a Linux firewall box to
failover to a single backup server, while preserving connection state.
This question has been asked before, but the latest reference I can find
is from 2004, at which time Linux had no equivalent of OpenBSD''s pfsync,
though Harald was said to be working on one.
Did anything come of those

Centos box and Cisco 3750 VLAN's
Hello all,
I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's
(counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the
Cisco switch was not partitioned into VLAN's which means that the only VLAN
running on it was the default one (VLAN 1).
I have then played with VLAN's a bit on the switch and at this point have
two: VLAN 1 (which is default and can

failover with conntrackd
Hi.
Is anyone using conntrack-tools to implement gateway failover on a
network with windows clients?
I set it up with ucarp and keepalived, and found that gratuitous ARP
doesn''t always seem to update the cache on Windows machines. It works
the first time, but if a second failover happens, the client continues
to send stuff to the wrong MAC address. Linux machines work fine.

What failover solution for advanced router ?
Hello,
Could someone experienced suggest good solution for failover
advanced router ?
The router for which I need redundancy is quite complex:
1) has 5 interfaces
2) uses the same network and the other network IP aliases on some interfaces
3) uses bunch of policy routing rules
4) uses proxyarp feature on some interfaces
5) uses complex iptables setup [propably not important in this

What's preventing you from using CMake?
Is there some problem we can solve?

High-Availability shorewall
Hi all!
I think I remember there have discussion on this topic on this
mailinglist a while ago.
But the archives don''t find anything.
Did anyone here set up a configuration with shorewall and heartbeat
or vrrpd or ucarp?
What would you prefer? Any experiences with failover times, setup
problems etc? Good documentation on this?
Thanks,
Christian

Re: [Nemo-devel] nuts status page
Adam: Thanks for putting up this page. But something is wrong. In
particular, our Powerware 9135 is a three phase UPS system with THREE 480
volt outputs. So the displayed voltage is not correct -- in fact there
should really be THREE voltages displayed, all around 480v.

Using Akima with nearly-gridded data
I am using the Akima interpolation package to generate an interpolated
color contour plot. It is working very well, except for one problem.
The data that I have represents real-time readings from a thermistor
string vs. time, so the data points are often very nearly in a
rectangular array, since the thermistors are read at regular time
intervals and they are equally spaced physically.

Help! VLAN tagged traffic not shaping :-(
Hello,
I have a linux box sitting between (and bridging/firewalling) 2 LAN segments.
I''m using Bridge/Netfilter/IMQ/tc(htb) to control (shape) mail/web traffic that
traverses the 2 networks.
The networks also have some VLAN tagged traffic flying around. My linux box
behaves OK with VLAN traffic except that the shaping doesn''t seem to work.
Normal http shapes alright but as soon

simple tbf rate clamping issues
Hello,
I was attempting to throttle egress traffic to a specific rate using a
tbf. As a starting point I used an example from the LARTC howto, which
goes:
tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540
I then attempt a large fetch from another machine via wget (~40 megs)
and the rate was clamped down to about 12Kbytes/s. As this seemed too
much, I gradually increased

Vlan classify
Hi;
I was wondering about splitting my Ethernet in different Vlan. But is
there any functionality in iptables, or any other tools, witch I can use
to match a specific Vlan? I was thinking about marking this
packet and then classify it to a appropriate queue.
Another question is:
How many packages can a ordinary pfifo queue hold??
Say, packets that are used are full Ethernet frame.

lc shaping in- and outbound traffic on same box
I''m looking for a way to shape all traffic on a virtual vlan interface,
say eth1.100 to a max of 100mbit. The box is a quagga router with eth0
on the inside and vlan interfaces on the eth1 card to our upstream
partners. Each partner has his own vlan on eth1.
I tried shaping but was only able to shape outbound traffic on the
eth1.100 interface. Inbound shaping was also possible, but
