I've had BA schedule their tech to come in on the COVAD install 3 times now. The first time they sent someone in on a day I told them I'd be out. The second time no-one showed up, but they closed the day with "customer not present" on the ticket (and I was at home from freaking 8am to 5pm!), and the third time the tech called me but *HUNG UP* before I could pick up on the second ring.

Actually, would't re-export of a read/write nfs share, as done by sunos nfs servers be prior art?
I.e. The motif or openlook file manager is the user interface. There being one "database" server, which would be a main NFS server, and their being "intermediate" servers which are servers that mount the main server and re-export it to nearer servers (I've seen such setups in university environments, for some reason).
In fact, isn't this the core behind a standard AFS setup with a caching local copy of data read?
Filesystems are just simple databases.
I'm sure that the IMS and other hard-core database folks could come up with other examples of this kind of method being used all over the place.
This stuff is great. I've heard about these before, but I'd have given my right arm to have been able to track these down last year. I like the software solutions, but I'd definetely like to use these, too.

Have you priced out a pair of fibre channel arrays, a fibre channel extender (over dark fibre or oc3) and a raid 1 driver? It'll be slow as shit (speed of light for the data to travel through the fibre channel->WAN->fibre channel) but it'll get all of your content somewhere else in real time. It'll probably cost you as much as an EMC box, though, which does it a bit more... sanely.

Really? The following code looks pretty foolproof (from bonding.c, bond_xmit()):
while (good == 0) { slave = queue->current_slave->dev; if (slave->flags & (IFF_UP|IFF_RUNNING)) { skb->dev = slave; skb->priority = 1; dev_queue_xmit(skb); good = 1; } if (queue->current_slave->next != NULL) { queue->current_slave = queue->current_slave->next; } else { queue->current_slave = queue->head; } }

You can avoid the problem of having to share the channel between switches by using spanning tree to shut one off until it's needed. This ensures that only one interface and switch pair is active for a particular bonded address at any one time, eliminating the need for the switches to have to load-balance between those 8 channels that they have available.
This solution expands to an arbitrary number of switches and an arbitrary number of host interfaces.

Have you ever talked to someone who has had sun consultants come in and try to do a sun cluster install? Maybe they've gotten better since last year, but I talked to at least 2 companies that had been over-promised a working solution by sun. One company ripped sun's work out of their data center (sun didn't have the cluster working a couple of months into the project, and the 3rd party worked far easier and faster) and the other settled for a reduced spec.

And bay and ipivot. It works, and it's a publicly available RFC. Much nicer situation then HSRP.
and, FWIW, I doubt simple channel bondig would help, either
Actually, this should be doable with channel bonding (where the MAC address is identical across all interfaces) combined with a conservative spanning tree configuration (having trunking between both switches would be sugar on top, in case of the upstream interface dying on the switch).
1) Compile the kernel with the bonding device as a module. 2) Set your ethernet cards up through a bond device. 3) Plug NIC #1 into switch #1, and NIC #2 into switch #2. Let's say they're on vlan 100. 4) Trunk vlan 100 between the 2 switches. 5) Set your spanning tree config to favor devices seen through switch 1 (your primary). 6) Activate the bonding device. Once you do this, both switches will see the same MAC address, and switch #2's spanning tree config should cause it to administratively shut down the port that is connected to NIC #2.
What happens next is that all traffic goes through NIC #1, and switch #1. However, if switch #1 goes down, or if NIC #1 goes down, then switch #1 will surrender to switch #2 and allow switch #2 to bring up NIC #2, which will share the same IP address and MAC address as NIC #1 (read the doco for the bonding driver if you don't understand how this works).
Actually, this doesn't even require trunking the vlan, but it does require that you have switches that have spanning tree, that you pay careful attention to the spanning tree config, and that both interfaces can see each other so the spanning tree config will isolate them on the network.
NOTE!!! YMMV I don't know for sure that this works under linux. I know that this config should work with sun trunking, and reading the bond_xmit() function in the bonding driver it looks like it should work. I will test it on some cisco equipment if I get a chance.
If you want me to help you set this up, send me email, as I'm available to do such work.
I think the first question misss that even if the patch is distributed seperately a customer or client or whatever has to apply it. The resulting binary almost definetely falls under the GPL (remeber, the patch had to be applied and compiled - the sources were combined).
If, again *if* it is distributed, then the party at the receiving end is entitled to the complete source code for the resulting, GPL licensed, application since it was integrated with the patch and the program before distributing it.
I disagree with the common notion on Slashdot that just because CSS doesn't prevent all copying, it is worthless as a copy protection. If we could all burn DVD's for a buck or two like CDR, the movie studio would lose a lot of money from decreased sales.
If you visit china you can return with a suitcase full of pirated dvd's. To me this substantiates the claim that css is ineffectual as a copy protection measure, since these DVD's can be played on any player. Unless you're running linux. Then you need DeCSS or a dxr2.
I think you are suggesting that traceroutes will give the information needed to give a server knowledge of a clients net.location?
Remeber that program that looks for traceroutes and sends back fake information?
