I just got hit with a whopping bill by my provider, and noticed they charged almost twice the bandwidth I was showing in my Cacti graphs.
I looked at the graphs they provided, and it seems that rather than averaging in/out bandwidth on the swich port, as the default Cacti installation does, they were treating in and out as separate switchports and totalling the bandwidth (at least I think that's what's going on).
Just wondering if this is a standard practice among providers. Attached are my and my provider's graphs.
I've been with these guys for years and never had this problem, until I had a big spike in incoming bandwidth which apparently skewed the usage. Prior to this, overrage charges have always matched bw shown in my Cacti graphs.
I was wondering what is the best backup method for 2 servers with over 3TB of data? Need the best backup solutions so if something happens sites are easy to get back online.
I run special software that is similar to a gaming server. It operates mostly in SWAP memory because 99% of the time its idling. Each instance uses about 5MB of physical memory and 50MB of SWAP memory. So I am using about 2000MB (2GB) of SWAP memory and 250MB of Physical memory. To my understanding, most Virtuozzo VPSes count SWAP memory as apart of the burstable memory , so finding 2GB of burstable is not likey or cheap.
Virtuozzo with the SLM method of handling RAM seems to be my only option because it allows for no set limit of burstable RAM. I am wondering if there is any other method or technology that could allow me to actually use high amounts of SWAP memory, as it should run from the hard-drive, not taking up the faster physical memory.
I am currently consider XEN servers, but I was unsure if they could handle the SWAP I need, I emailed Ray at BigVPS.com and he stated his XEN servers can handle my requirements, but would need an extra $5 for the extraneous SWAP usage. Is it true XEN can handle what I need?
I was hesitant to even post this because I've been on the net for so long, that and I know just about every method out there. However, large corporations obviously can't live with loosing data so I figured I'd see what everybody else is doing out and figure out my next battle plan for archiving data.
Here's what happened. I had triple backups of some data. I burned them twice on DVD (yes, two DVD's of each archive) as well as had them on a WD hard drive. ALL are dead or unreadable. I had the discs in a DVD binder and they were never touched for a good 5 years. I put them in a player (multiple players) and only certain parts were read.
Other parts came up with errors. (Yes, I'm aware there are companies that offer recovery for both CD/DVD and Hard drives, but they always charge a fortune and in some cases, aren't worth it). This was Memorex media btw which might of had something to do with it, but at the time I thought it was the best. Next I went to the hard drive. This was stored in a room temp house over a good 5 years and when I plugged it in to a computer's IDE port, nothing. Not sure exactly what's wrong with the drive and I'm sure it could be fixed and recovered, but once again, that's not my question.
My Question: What methods are you using to store your archives over long periods of time? Any recommendations on hardware? I'm thinking of DLT Tape backups and of course doing RAID next but don't want to run into the same problem in 5 years. How can I sleep at night (which is already impossible) knowing that in 5 or 10 years when I'm ready to get into my backups that they will be there?
What are you doing and what do you recommend? Better yet, what the hell is Hollywood doing to keep all their music and movies safe?
I see that mod security is an option in whm > apache compile. Is this a good (and improved way) of install modsecurity over the old cpanel add-on from back in the 10x versions?
Also, can someone point me to really tight, yet reasonable mod security rules for these server settings?
#1 centos cpanel with phpsuexec apache 2.2 php 5 mysql 5 a few shared domains (main business box)
#2 centos same as above, but apache 1 / php 4 / mysql 4 (shared / reseller hosting server)
I'm in the process of forming a web development business and am currently interested in learning the various methods of offering 3rd party services and accounts. How to offer hosting is my current dilemma; I can of course refer the client to a host and receive a referral kick-back, but the idea of reselling hosting accounts is also appealing, though I have no knowledge currently as to how this works, and I'm basically just curious how other's manage this aspect of the business. I do not mind offering customer service on hosting accounts, so this is not an issue
I've got two domains (for sake of example, domain A and domain B). Domain A resolves correctly to my web server. Domain B is just sitting collecting dust. I didn't set these domains up, a previous programmer at my job did.
How do I configure resolv.conf, named.conf and the zone file(s) correctly to have domain B redirect to domain A?
I've already set up httpd.conf so that any requests for the host name of domain A will redirect.
e.g. [url]-> [url] I just need the DNS part of this fixed (that I'm a bit of a noob at).
Do I have to do something like this in named.conf:
Code: zone "domaina.com" { type master; file "/var/named/domaina.com.hosts"; };
zone "domainb.com" { type master; file "/var/named/domaina.com.hosts"; }; Then in the domaina.com.hosts zone file add an alias like this?
Code: domainb.com. IN CNAME domaina.com. Or do I need to create a domainb.com.hosts zone file with basic info emulating domaina.com.hosts zone file, and add its entry in named.conf?
I have dedicated server at GoDaddy and I am hosting very important web service for our company. We have only one HDD on server and no FTP backup. What is the best method to protect data and whole server from HDD crash? Is it enough to add second HDD?

then i get the error below. Can anyone help me out? i really dont know what todo here.
Checking Update System........Your operating system's rpm update method (yum) was not able to locate the glibc package. This is an indication of an improper set up. You must correct this error before you can proceed.
I want to try something different on our methods of replacing or upgrading hard drives.
I want to be able to do most of it via our KVM/IP instead of babysitting the server(s) for so long in the DC.
My thoughts are, how can I add the new hard drive in the DC, and move the data over via the KVM/IP. Can this be done with just a raw drive added (no new setup) using DD or even rsync, or is it better to setup a new installation of CentOS on the new drive, and use rsync to move the data over. Then how do I get the proper drive to boot until I go back into the DC to remove the bad or old drive? I'd be interested in how some of you folks are doing this, as far as what's easiest and could be done over the KVM/IP once the new drive is connected.
Or on systems that have 2 drives with cPanel/WHM, how can we temporarily on an emergency basis untilize the backup drive to do a new setup, copy the data over from the drive that is failing, then just replace the bad drive as a backup drive next time you go in the DC? We have an external USB CD in place to allow remote installs...just curious if anyone does something like this or has ideas how we could make this work.
We use cloning software now, but can end up babysitting a clone for a long period in the DC like this.
I have mod_security setup in WHM and am seeing a lot of these entries for various IP's.
Access denied with code 406 (phase 1). Match of "rx ^((?:(?:POS|GE)T|OPTIONS|HEAD))$" against "REQUEST_METHOD" required. [id "960032"] [msg "Method is not allowed by policy"] [severity "CRITICAL"]
There are several methods of offering network path redundancy. The basic decision for me has come down to:
Do it at Layer 2 Do it at Layer 3
At the moment we have layer 2 redundancy to each server. 2NICs on the server up with one having the IPs for apache/mysql/etc. each nic going into a seperate switch and the switches connected together, with 2 routers running VRRP to handle the gateway. Everything is Vlaned.
So basicaly the switch redundancy is done by spanning tree and the IP redundancy is done with a process on the router/server to move the IP to the other router/server NIC if there is an issue.
I am thinking about going with 2 fully seperate networks. in differant subnets. where each router would have a gateway. the routers would talk to each other and they would speak OSPF or ISIS with the servers. This way I would move hosting onto loopback IPs on the servers and those loopback IPs would be advertised to the both routers through seperate networks. Again everything would be Vlanned.
This has the advantage of getting rid of spanning tree which has caused issues from time to time. It would keep redundancy up and we could standardize on the routing daemon ran on the servers allowing all of the various OSs we run to have the same basic config for network redundancy. Where now each OS tends to have its own solution. This would make life easier from a config and troubleshooting point of view.
After some experimenting with Linux VPS setups, I'm eager to explore windows VPS software.
Two questions I guess, first off, what is the cheapest method of offering multiple VPS accounts on a windows server? Are there any free or build in Microsoft methods?
Second, what is the easiest way of doing so? (Simple setup, as hands off as possible)
I realize the cheapest may not be the easiest and vice versa. I'm downloading Parrallels Virtuozzo trial right now, but would like to learn what else is out there.
I got new server for free image hosting services, I was reading up about lite speed and it seems faster for this type of need however i do not have money to buy enterprise edition now, standard edition which is free but it says only 150 concurrent connection, means i can't have more than 150 ppl viewing a image? please advice or do stick with our great Apache which free
I have an error that has arisen me for no apparent reason. This error does not allow me to enable or disable DNS domains. I searched for solutions but have not found anything.
The error message is: ERROR: Call to undefined method plesk__client__domain__dns__toggle::_postRequestRequired() (DNSToggleUIPointer.php:26)
And as I said DNS appears when activated or deactivated by the domain from Plesk panel
I'm sure there is an easy answer to this, and i'm probably being a little lazy, but the google searches i did didn't really help.
As I need to have windows hosting, apart from the price, is there any difference between setting up the server with windows 2003 standard edition and web edition?
I want to run MS SQL and My sql databases, run asp, .Net 2 and php on the server.
I'd also want to connect with RDP which i'm assuming is fine.
Most of the searches seem to talk about the fact that you can't set up active directory,or making it a domain controller but not much else.
