If you are using HP machines (other mobs may have a similar setup) you can take advantage of iLO - Integrated Lights Out. It is a 2nd or 3rd network card in the machine that acts as a management interface. It can be accessed by telnet, ssh, or web (hopefully your core network is still up) and provides access to virtual power buttons, mounting ISO's remotely for full system rebuilds, etc. I spec it in standard with all my server purchases. In scenarios where you are co-locating then this is a must. Providing the network is up and the power cable is plugged into the server (whether the server be physically on or off) then you have full control over its behaviour. Worth a look into.

Their stuff is good, but on the whole very expensive.
VMWare, Xen, UML etc all offer remote "power cycling" of hosted domains, but of course, if the root domain goes down you're still stuck. Needless to say the other advantages of virtualisation make it pretty attractive.

I recently picked up a second hand Compaq RILOE card on trademe for about $70 (there's still a few there). Provides local console redirection via http, keyboard/mouse intercept, remote power control (with a custom powercable that fits in between the physical power button and the psu), etc. These models are a bit old now, but the modern equivalents (such as the realweasel) look good, and I'd consider them well worth the money.

Adderlink.
We use two (Ak/Wn) attached to our 16 port KVM's to provide IP access to the consoles.
The box has one network port and runs a commercial version of VNC, which behaves better than free VNC.
Attach it to a UPS, and you can have access to your consoles with power on or off.

Im wondering if anyone has used or is using a good solution to remote boot (from complete power down) servers and equiptment?
This i have done in the past by having the bios on the server set to reboot after power fail and that takes care of the rest along with good load UPS's and backup power. But what if you acually had to shut down a server for some reason out-there (backup power fails)?
Most of the replies to this ignored his last sentence. Many (most?) of the BIOSes/motherboards I have seen can either be in "Power off" or "Last state" when power is reconnected. Few have a "Power on" option.
If he shuts down a server, the hardware will power down, and when he power cycles with his remote power strip, the box stays in "Power off" or the "Last state" which is.. off.
If one looses power at a site, the servers reliant on the failed power rail should shut themselves down before the UPS runs out, in order to prevent filesystem corruption, which can prolong an outage.
I see the only real solutions to this being some flavour of lights out card, or of course, monkeys with cellphones.

You beat me to the punch Neil. The problem with 'a little knowledge' is you end up with a rash of 'Help! I'm being DoS'd by (insert IP of your ISP's DNS Servers here)!!! BAN THEM!'
Aka the little bit of knowledge is 'knowing you need a firewall to be safe' and the better bit of knowledge is 'knowing the difference betweem an attack, and innocent / important internet traffic'. Or at least how to find out the difference!
But yeah, given the lack of PR that "Online Security Day" received in the IT Community it can hardly be given any sort of credibility... you think buy in from a few major IT outfits and ISPs would be kinda useful?
Almost as press-worthy as Microsofts announcement re Maori language support in Windows XP? (When its been available to varying degrees within alternative OS's for quite some time..)[1]
Mark.
[1] I give credit to the fact they've finished it and packaged it. As I understand it most of the Maori Language work for Linux is in an incomplete state.... then again when you're throwing thousands of dollars at a project you can expect to have an edge on small open-source efforts I guess!

We're using it extensively. We're offering it as a product to customers, running DNS, qmail, apache, and a number of custom apps on it. The stable releases are rock solidly reliable, and the development efforts behind it are giving it new features all the time. At the moment with stable releases you're limited to running a domain on a single CPU, which is a bit of a pain, but the next release is going to include virtual processors, so multiple "real" processors can be sent instructions from one master virtual processor to which domains are assigned.

Hi There,
I have been discussing the utilisation of Xen in a production environment on a couple of other lists (nzlug, debian-isp etc), but wondering if anyone from this list is using it in new zealand for serving of network services? Please let me know if this is OT.
Would like to hear your experiences if so.
Simon

I've deployed a Xen machine together with linux vservers inside the virtual Xen domains (don't ask)
Running exim4/apache/samba/ldap and maybe some other things. Has been in production for several months now without any issues.

Can I ask why you would choose this over using something like FreeBSD jails which provide seperation with no overhead?
