Need a good DNS service provider

Presumably with this you could hook up a keyboard and a monitor, and change the BIOS settings so that it would power up automatically...

For what you are describing, DynDNS has the best solution for you.

You can also run a client on a PC that can update the DynDNS servers when your IP changes, it doesn't *have* come from your router.

I know that but we have to leave a pc or mac running when we're gone and how do I ensure it restarts after a power outage. We have frequent power outages that exceed the ability of our UPS to keep things running. I could buy a generator, but a router that restarts every time is cheaper.

I have a panasonic ethernet camera that has a dynamic dns client built in and a free dynamic dns service to use.

Might be a cheap solution.

JRC do you have a model number for the camera? I'll check it out.

Most PCs can be set to restart, it's more of the odd one that can't. I *know* Macs can, because that's what I run my home automation system off of. Indigo on a Mac Mini. http://www.perceptiveautomation.com/indigo/index.html

Some UPSs have intelligence that will send a signal to the server to shut down gracefully if power is out more than a few minutes then send a boot signal to the server when power is restored. This is not a server function but a function of the UPS.

Thanks for the info. We'll look at it.

Another option to look into on restarting the system after a power outage would be Wake-on-LAN. It uses the network to restart the system by sending a "magic packet" to the system.

http://en.wikipedia.org/wiki/Wake-on-LAN
If the pc supports this might be a nice way to restart. Some UPS systems and routers offer this support also ( see below) but if your staying with the current model you could do this manually from a website etc.

If accessing BIOS isnt an easy option might also contact HP to see if they have a solution for you.

I'm using a Panasonic KX HCM10, It's pretty old. I got it for $10 at a yard sale. The newer ones are more pricey.

I must be hitting the wrong yard sales...

HP designed it so you can't access the bios (no crt, mouse or keyboard ports). I called them and they suggested I buy a new HP server since the new ones auto start.

Sounds like you have two problems to solve.

For your DNS I agree dnyDNS is a great solution for what you're looking for provided your address doesn't change often. Before going down that road I would find out what the lease time your service provider's DHCP server is handing you for your address. Many keep those short because they have a limited pool of addresses to play with and they cost money if they are not cycling off freed up addresses quickly meaning that address you're issued is bound to be released and handed back out should your system go off line.
If it's that important to be able to access your system and not have the IP change on you I'd really consider getting a static one issued.

Now as for your power, have you considered an IP based PDU? Basically it's a power strip you can control over wire, and power on any outlet remotely. Super handy to have. Unless you blow a breaker you'll always be able to bring your system up.

That won't work for his case. The problem is that the PC requires a physical button push, it doesn't power on automatically after a power failure. The other problem is that after a power failure his cable modem reboots and he gets a new IP address. Without a device that can register to DynDNS for him, he wouldn't know what IP to access the PDU on, and even if he did, it wouldn't re-power his PC anyway.


The easiest solution for this case might be to setup a simple circuit that would click a relay upon powering up. Tie the relay into the power switch of the PC so that it gets the button push it needs after a power failure.

OP's need is to be able to contact the server(s) at the house one way or another. Having a fixed IP is one way, using dynDNS would eliminate needing to have a fixed IP. If you can get to it by the name registered via dynDNS, then you don't really even care what the IP underneath that name is. (That also depends a little on the specific remote access software, some of it is old enough to only allow putting in an IP address, but most of it is bright enough to accept an IP or a name.)

The dynDNS registration could be done by some other system in the house, it doesn't have to be that server. Unless the server is plugged directly into the cable modem (which is unwise these days) it's really the router that is doing the DHCP negotiation anyway. Newer routers have built-in support for registering with the dynDNS (or similar) service after the IP lease is established.

Getting the server to power on when the power comes back becomes the biggest problem. The BIOS isn't set to allow auto-power-on, and without spending some money on a KVM interface (as I posted above) you're down to hacking a relay into the power button, or making some sort of solenoid that physically presses the existing button. Essentially you'll end up needing some sort of home automation controller to control the thing that will power on your home automation controller.

Another thing to consider is that you may not *want* the server to come back online immediately after power is restored. If it's partway through coming up and the power goes out again, it's unlikely that the UPS would have had enough time to charge to allow a graceful shutdown, so you'd end up with an ungraceful one. There's a lot of disk activity on bootup, so you end up playing Russian roulette that any given set of disk writes are going to make it out as a group. Eventually you'll lose that bet, which could cause filesystem problems that might kill the entire server. (Or at best, require some filesystem repair that you aren't going to be able to initiate remotely.) Ideally it would wait to boot up until the UPS could guarantee enough coast time to shut down.

In the end...it might be time to find a smarter server.

Now that's an interesting idea! I'll have to think about it.

What I've done in the short term is that I have ordered a router that has a client update function. It will notify dyndns that our IP has changed and provide it with a new one. We'll see how that works after I get it and install it.

[Lakepilot]

I got the DLink DIR655 router from B&H photo.

I tried and tried to get it running with dyndns and couldn't. I noticed that DLink had a free ddns update client for that router. I tried that and within 5 minutes had it all running. DLink uses dyndns for their service, but DLinks instructions were spot on. Dyndns doesn't really want anyone to use the free service so they make it a bear to use.

Metrocast won't provide a static IP address unless I sign up for a business service - and that's a lot more money. I called them and they said IP's are assigned every few days. I still have the same IP I had when I started the thread.

Now as for your power, have you considered an IP based PDU? Basically it's a power strip you can control over wire, and power on any outlet remotely. Super handy to have. Unless you blow a breaker you'll always be able to bring your system up.

The problem I have is that once the AC goes away, the server won't start, even when the power comes back on. HP doesn't give you control over anything - like the bios - to tell it to turn on, so a plug strip won't do any good.

Thanks for the ideas though.

Thanks for this info, it's great. He makes a device that allows you to hook up a crt, keyboard and mouse to our server. There are others that have published how to hack the BIOS to get it to restart automatically on power fail, so the two could do the job. It bugs me to no end that we were one of the first to buy one of the HP servers and as pioneers we got killed. Now they want another $1,000 to buy a whole new server to fix their problem. This guy is selling access to the solution for approx. $80.

The problem I have now is we're pretty far down the road of getting rid of the HP server and never going back. They got me once and I don't want to give them another chance.
