So What Exactly Can Take Down An Entire Vps Node
Jul 21, 2007
I figure while I am twiddling my thumbs here waiting for my host to tell me what the heck happened for the second time in two or three months why they have to do an entire VPS hard restart, which of course causes another hour of fck delays, that I'd ask some of the more skilled and experience folks here, how?
Just before it happened, as I was watching, the load shotup over 1, 2, 4, 20, 30 boom. (I opened a ticket at 4)
Shouldn't virtuozzo always guarantee a certain amount of cpu and bandwidth to the node root? Why do they have to hard reboot and not access it directly and stop the badly behaving vps? Better yet, why isn't the badly behaving vps stopped automatically by virtuozzo?
(oh and am I an idiot for putting up with over two hours of downtime?)

We have one Cloud Server hardware node that exists only as the backup location for containers and VMs in Cloud Server/PVA (it hosts no virtual servers). Can it also serve as a Backup Server Node?
A related question, in my case, is whether we can configure a Backup Server Node to use a particular drive/mount/directory, as we can with PVA? I couldn't find any info in the docs about any settings at all for the Backup Server Node.

I always use Apache and it's easy to redidrect an entire domain in the htaccess.
Code:
RewriteCond %{HTTP_HOST} ^www.domain1.com$
RewriteRule ^(.*)$ [url]$1 [R=301,L]
For a site I'm working on I need to achieve the same thing with IIS but have no idea how to and the technician claims it can't be done. Surely, that's not the case. Any ideas?
By the way I want the exact same effect as the above not just a generic redirect that sends everthing to the home page of the new domain.

I have come across an issue where traffic from India is hurting my business. What I have is a number of job boards. Realistically, the only issue I am having is with IT and Engineering positions being applied for heavily by people in India. Since my customer base is all in the USA, I would like to just block India.
While I know this is easy with Apache using a .htaccess file, I am using IIS on server 2007. Does anyone have any idea on how to do this easily with the large number of IPs that India uses?

how to ban an entire top-level domain? For example ban everyone from Russia by coming from the .ru domain? Or everyone from Lithuania by somehow banning everyone coming from .It ip address.
I've had some people from those places try to hack my site and am fed up with it. So I want to ban those two entire countries for the time being using cPanel X's "IP Deny Manager".
By the way I am not a technical person. Just your every day person running a site.

we dont host our own website, but recenty our server crashed, and our hosting provider was supposed to be backing things up. They told us that the entire server crashed and the backups were on the same server so we lost everthing. we actually did end up getting evertying back but it took nearly a week to get back online. they said they are now backing up everthing in a remote location so this wont happen again, but we dont want to put this in their hands anymore, we didnt even get everything back .htaccess, hidden files, subdomains were not backup up and lost. So we want to do our own backing up.
Is there some thing I can set up as a cron task to weekly automatically backup every single file on the server, and the database?
We think this would be very beinificial to us as we lost alot of money from this ordeal and we do not want it to happen again.

Just got off the phone with tech support and they noticed that someone was trying to gain brute force entry to our VPS. We want to view our logs but can only see the last 250 lines or so when using this command inside putty:
tail -9000 /var/log/messages
How do we see / copy the entire 9000 entries to view in a text editor? Any tips would be great. I am a newbie at this.

The backup program (cpbackup) that comes with WHM/Cpanel is not ideal for our current situation. We have lots of third party applications installed on our server along with many customized configuration files. We need a solution that will backup everything and allow for fairly simple restoration.
How viable is rsync for full server backups? Can it handle 100 GB of data?
More importantly, how would you restore the backup to a new server? If the new server already has an OS the restored files would break the system, right?

Yet another question for you all. As part of my remit I need to work out power usage across the DC. It's not huge. Approx 300 servers across 50 physical servers (BL7000c with BL46x series blades) as well as several sans/disk arrays (DotHill, HDC, HP MSA) and appliances, Ciscos, POE 8xxx series procurves etc)
All these are racked up and being fed from 32Amp APC PDUs (without monitoring). It's three phase in, single phase out. We can't really run 3 phase because I am not allowed to run it due to the 6 foot rule.
Our UPS is rated at 30KVA but we are running it at the max at around 24KVA.
What I need to do, is work out on an individual basis how much power each one draws, ideally without a power down. The reason, as well as identifying the power hogs (such as several SUN V series servers), is to reduce the overall carbon footprint and energy costs.

to get a copy of their entire site onto our servers.
The problem is that they have no backups, and their current host has denied them access to their account. (It's a long story.)
Rather then try and fight with their old host, I wonder if it's easier to just run some kind of "website copy" program and grab a copy of all pages and images, linked files, etc..
Their current website pages are served using an ASP database application, but the copy they need only has to work. It doesn't need to be dynamic, etc... as long as all the pages are there it's good.

I'm contemplating creating a website that could store extremely sensitivity information. It's more than likely that a MySQL database would house this information.
My question is. Does anybody have any experience when it comes to encrypting an entire server disk?
I've searched online with disappointing results.

Which version of PHP is recommend?

I've looked into WinCache how to install it and hook it up to php, but i'm guessing you add the extensions in the php.ini?

A single website is returning 503 to every request - it's a wordpress site - and we have a lot of those, none of the others are returning the same errors, so this is quite odd to me:
141.101.70.247 - - [03/Sep/2014:08:29:36 -0600] "GET /apple-touch-icon.png HTTP/1.1" 503 1330 "-"

I do see some ModSecurity warnings from last night:
[Tue Sep 02 23:07:58 2014] [error] [client 141.101.98.8] ModSecurity: XML parser error: XML: Failed parsing document. [hostname "WEBSITE.co.uk"] [uri "/xmlrpc.php"] [unique_id "VAaiLrhfKCIAAAvNboMAAAAP"]
[Tue Sep 02 23:07:58 2014] [error] [client 141.101.98.8] ModSecurity: Access denied with code 400 (phase 2).
[Code] .....
but no errors in the site error_log since that last one - all I see now is 503 errors.
How to proceed with debugging the cause of this?

We are resellers from ResellerZoom / ModVPS, at this moment we have about 10 accounts (8 reseller accounts and 2 VPS).
The problem starts some days ago, when they do a servers cage movement having us offline for about 8 hours at various servers.
Well, we have experienced various connectivity problems with them, and this was a major problem but we waited fine.
Yesterday. we receive an e-mail from a VPS client telling us what their sites are all showing codification problems. We opened a ticket with ModVPS and just wait their reply.
They told us that we should contact the script developer about the errors, but the problem appears at a lot of different scripts hosted on the same cPanel account. Because that, all appears to be a hacker attack.
Then, we consider that the better solution is to restore a full VPS backup, and we communicate this to ModVPS staff. And... Surprise! ModVPS don't have ANY backup for our VPS. Anything! That was one of my pre-sales question, and at that time they warrantied us a weekly backup.
We are still trying to get contact with them, but at this moment has passed 17 hours from their last answer and we are still waiting for it.

We needed to delete a domain which has been terminated by a customer. This customer has about 40 domains linked to them.
When we deleted the domain, it deleted the entire customer!
I'm trying to find the support option on your site but I can't find it, there's just no support option for Plesk anymore.

Upgrading was started not half an hour ago from the time this post goes out, all went well until the MySQL was started up. At this point it is screaming at me because it cannot access it due to a missing password. This shouldn't be to much of an issue, as you just follow this post here, [URL] .... However.. when I did that this happened.
Code:
/usr/local/psa/bin/admin --show-password
PHP Notice: Undefined index: PARAMETERS; File: /usr/local/psa/admin/plib/CommonPanel/Exception.php, Line: 266
SQLSTATE[HY000] [1045] Access denied for user 'admin'@'localhost' (using password: YES)
I rent through OVH, so we don't get support access or anything. We just get a 15 site license and that's it so I don't know who to turn to for this.. I haven't ever touched anything in regards to SQL and the likes, all I did was click the upgrade button and this failed me. And now I've pretty much lost everything until this is resolved.

I want to build a VPS Node using Quad Socket Tyan Motherboards and AMD Opteron 2376 Shanghai 2.3 GHz Processor (Quad Core).
I am in doubt since I notice that some providers (at least two rather big provider which I have account) are using Dual Core AMD Opteron 2212.
Is there any specific reason why those providers is not using 2376 AMD Processors? .. is it because the Dual Core AMD Opteron 2212 supports Virtualization Technology, while the 2376 is not?
I will use Xen Hypervisor, usually I use Intel 54xx Processors but looking for *cheaper* solution , so I am really new in AMD Base Server.

I build raid10 for VPS nodes. Now, I will use SAN, so all VPS will be created in SAN. With the host server, I assume that I don't need fast disk array, because all the disk requests have been processed in SAN already?

For a quad core processor with 16-32GB RAM and SAS raid 10, would 30 VPS's be a lot?
I have a VPS with 1Gb RAM on a machine as above. I'm running about 40 (relatively low-volume) websites on it. Seems to me that if 30 others were doing anything similar, that would overwhelm a single machine.
Am I just making an uninformed bad assumption? So far, performance on my VPS has been fine.

Well the age old question for virtual servers, would you rather a host put all his eggs into one basket "monster node" or several smaller ones. From a provider standpoint one server is easier to manage than several, although if that one goes down, all your customers do with it. Lower costs for the provider, s/he can then pass the savings along.
Example Package:"2GB Ram Packages, 500GB bandwidth, and 20GB space."
The "EXAMPLE" Specs.
All in one
Max Clients: 126
4U Rackmount,
4 Quad Cores, "16 total cores"
256GB DDR2,
8 600GB SAS 10k,
RAID10
Several Server setup:
Max Clients: 14
1U Rackmounts,
Single Quad Core, "4 cores"
32GB DDR2,
2 300GB SAS 10k,
RAID1
If you could tell me why you picked either or.
