True, pre-installed would be the way to go, if 1. you want DD-WRT, and
not Tomato or one of the other firmwares, 2. you can get a router with
the desired hardware specs, and 3. at the price point you want.

If not, installing 3rd party firmware is pretty easy, as long as you
pick a router that has been well tested with your chosen firmware.

Some addresses changed to hide low horsepower boxes.  This is a

Note that I don't use the box to route anything, but it seems to
minimally work for itself; the admin session above is over v6.

I updated the Linksys' firmware to the current revision.  It didn't fix 
the Ethernet connection issues and that revision also does not support IPv6.

The new router I'm considering to purchase at present, is a Netgear.

Re: New Router Suggestions

[Anthony Gabrielson]

I don't know for certain - but I would guess at least most of their newer 
routers would support it in hardware.  My question is if you're going to 
install DD-WRT anyway why wouldn't you just go with a router that has it 
pre-installed?  Why bother with figuring out which device is ideal and doing 
the actual flash yourself...

Is that just the stok Linksys firmware? I would hope that DD-WRT or Tomato
would support IPv6.

I'm actually more concerned with service flapping than split-brain, thus the 
concern about latency on the heartbeat links.

Ah, split-brain!

Possibly you want redundant heartbeat links. (Even if you have only one 
link out, maybe bounce through different third points.)

Linux heartbeat and long-haul networks

[Richard Pieri]

Does anyone have experience with Linux heartbeat over long-haul networks?  I'm 
looking at setting up a failover between two sites.  Specifically:

I have two Xen dom0 servers currently in the same rack, using DRBD-backed 
logical volumes for domU images.  They currently use a manual switchover 
procedure.  What I want to do is move one of the two dom0 servers to an 
off-site data center and set up an automatic failover for my domUs.  The latter 
should be easy with Pacemaker but my concern is heartbeat latency causing 
spurious failover.

They meet at WPI, not Clark. I know Andy Stewart who is the founder of
the group, and I gave a talk there a couple of years ago. I believe
about 20 or so folks attend fairly regularly.
