hyper v - Wake on Lan for Dell Poweredge 2950?

itemprop="text">

I'm looking into the possibility of
using Wake On Lan for a machine used in a test lab to run VMs. It doesn't really need to
be on all the time, so it would be nice to be able to power it down when it's not being
used to save electricity.




Looking
through Dell's href="http://support.dell.com/support/edocs/systems/pe2950/en/engbrief/wol.pdf"
rel="nofollow noreferrer">WoL support documentation, the NIC (Dual Embedded
Broadcom® NetXtreme II 5708 Gigabit Ethernet NIC) should supposedly support WoL. The doc
is a little old, though, and doesn't discuss Server 2k8, much less 2k8
R2.



Nevertheless, one of the steps in the Server
2k3 configuration details specifies that hibernation support should be enabled; however,
when going into the power options for my server, there are no hibernation configuration
options in the gui.



I should note that my
understanding of WoL is fairly weak. Do systems monitoring the network for magic packets
need to be explicitly hibernated, and not shut off as normal? I wouldn't think that the
way the OS shut down the system would affect the motherboard's ability to run power to
the NIC, but then again this is not my area of
expertise.



I will assume for now that
hibernation is specifically required. Looking around some more, there seems to be
indication that hibernation is not supported for systems that run the Hyper-V
role--something to do with the Hypervisor. If this is true, it means that my desired
configuration would be impossible. Can anyone provide confirmation or additional detail
about this?

I don't
know this Dell system, but in all systems I know, you need to turn on WOL in the BIOS.
Hibernating Windows would then help with the boot time, but is not required per se.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
