Any Potential Dangers Of Using A Few Domains On Only One Shared Web Server
Oct 1, 2009
I have many website projects in mind. Some are more like a hobby, some are business(just for profit). I have lots of free time and I'm willing to work very hard. But the problem is that since I have many projects in mind, it may get a bit messy. I mean I'll get a different domain for all of them but how should I go about choosing hosts? One idea I have is to get one good(big space and high bandwidth) shared web hosting and use it for all of my domains. The advantage is that I'm not exactly sure about how much traffic my domains will get so it seems to make sense to get one big shared account for all of them. But if one of my websites starts getting lots of traffic, can I move it to another host and use the same domain? What would the disadvantages of doing that would be?

I'm using cPanel, and I'd like to change the IP address of all domains hosted on my server. When I click the "Edit DNS Zone" link in WHM, the IP address of all accounts is wrong. Do I have to change it manually for all of them?

i just had a simple question about wether there is any difference between getting a VPS plan (like that from jumpline) and a shared plan (like that from hostgator) for the purposes of hosting multiple domains.
It seems that for vps I have to create a "subdirectory" to create a new account for domain name. Plus the emails are all the same (so for example if I create joe@domain1.com and I have domain2.com registerd, joe@domain2.com will also work with the same username password).
On the shared side of things - I also do not get a very high level of isolation. Not like with reseller WHM package anyways. BUT the resellers lack the basic ssh access (at least the most favourables I looked at).
So i was wandering if anyone out there who is doing small-time part work and sells personal/business websites to clients knows which way is it better to go.
To get a VPS account and keep on creating subdirectories for each separate client (and hope they don't use the "other" domain names in the emails)
OR
get the shared account that allows unlimited domans
OR
something else.
I also forgot to mention that my budget does not extend beyond $20/month.

I've received the following offer to dedicated server. I'm planning to use it for small projects to begin with, and expand if potential exists.
That's the reason for my post today, I want to know if the deal presents decent value or not, and what could the server potentially be used for.
Celeron 3.2GHz
1GB Ram
1 X 80GB SATA 7200 HDD (after OS install, leaves about 55GB of usable space)
Direct Admin Control Panel
3Mbps / 3Mbps unmetered line. Roughly 900GB transfer per month.
$49.00 mo

If I were to build a 2.4 core 2 duo w/ 2gb ram and 4 x 500gb sata and 2 x 160 sata, both in raids. Do you guys think that would be above 2 amps usage? I was thinking maybe the efficient cpu would make up for the large amount of hard drives, all though their IO activity won't be that high. Maybe if someone has a similar setup they could shed me some light .

I run several sites and am wanting to setup several more. Currently I have two shared plans, but I don't like how the add-on domains are affected by the main domain (e.g. addon.main.com on 4## and 5## pages).
Is going reseller the easiest way for me to have these domains not affected by each other (a separate cpanel each)?
Finally, I don't use a lot of resources so are there actually reseller plans out there with lower prices (and lower resources too).

This question gets asked a lot in our Helpdesk and I figured I would post our knowledgebase article here to help anyone else wondering the Pros and Cons of Unlimited Domain Shared Hosting vs. Reseller Hosting. If anyone has anything else to add, I appreciate any feedback on how we can improve our KB article.
----------------------------------------------------------------------
Given the present state of shared hosting, many clients may ask "Why would I need a Reseller account if I can host unlimited Addon and Parked domains within a single shared hosting account?". There is certainly enough Disk Space and Bandwidth provided in many of today's hosting packages, so why bother to purchase a Reseller account?
Many don't realize the drawbacks of hosting large numbers of domains within a single hosting account until they've already packed tens of them onto a single package.
So how do you know whether a Reseller account or Shared Hosting account is right for you? The answer is in how you plan to provide access to others and how "mission-critical" the sites are. You should consider the following factors when deciding on hosting a large number of domains:
1. Who will be managing these sites?
2. How important is site security between sites?
3. Will these domains need dedicated SSLs?
4. How resource intensive will these sites be (RAM, CPU, MySQL)?
In a nutshell, Reseller plans are for those who wish to host websites for other sub-clients and a shared hosting package is for a single individual managing multiple personal domains. We'll go over the 4 points above in greater detail.
1. Who will be managing these site?
If you personally own multiple domains and wish to host them within the same hosting space, you can easily do so with an Addon or Parked domain. An addon domain will allow you to host a new domain within a subdirectory of your hosting space. A parked domain will allow you to have multiple domain names point to the same content. Since addon domains reside within the same user space as your main domain, you can manage all of your domains with a single login. You can see the problem if you want to provide another user with access. Since all accounts are managed with a single set of login credentials, if you give another user access to their addon domain you are also giving them access to your main domain. If you have vital information stored on your main domain and you are hosting another domain as an addon domain for someone else, you cannot provide them access to their hosting without compromising the integrity of your main domain.
When hosting sites as a Reseller, your clients in turn will want access to their account and will want exclusive rights to their disk space and server resources. With a Reseller account, each sub-account you create gets its own username, password, and isolated user space on the server. Individual clients of yours have access to their user space and their user space alone. In addition to the isolation with regards to access concerns, each account also gets their own cPanel access. All of the same great features that you use to manage your sites can also be given to your clients. Next time client Y wants to add an email account, you don't have to do it for them for fear of giving them access to your cPanel, you can simply give them their login details and they can manage their own email accounts.
2. How important is site security between sites?
This is along the same lines as point 1. This is not necessarily related to who you are hosting for, but what content you are hosting. Imagine that you are a webmaster and you are hosting your own personal site-in-a-box community forums (such as PHPBB or vBulliten) on your main domain and a company website for a paying client on an addon domain. It is not uncommon for popular scripts to have security flaws in older versions. Script authors will often update security flaws in later versions of their software. For this reason, it is very important to keep scripts up to date on your site. But let's assume you forget to update your scripts for a couple of months and an unscrupulous individual takes advantage of a well known security hole. Using this exploit, they gain access to your forums and any subdirectories. Since you are hosting another domain as an addon, they now have access to this domain's content as well. A site defacement on this company's site may not bode well for you when they are considering you for web master services in the future.
If these two domains had been separate into two individual users (i.e. two subaccounts created through a Reseller), their content would've been inherently isolated server side by Linux's user management. Sure, your forums still would've been affected by the security hole, but the break-in would've been isolated to your site alone.
Going back to our example, let's say that instead of a corporate website as an addon domain you are hosting an image gallery site for all of your cats. In this case, it may not be a big deal if a compromise in your main domain spreads to your addon domain. After all, they are both owned by you and you're only losing some time and effort to restore these sites from your local backups (which I'm sure you've actively maintained ). But then again, you are losing time and time is money. If these sites had been separated into individual users, again, you'd only have to restore one site's content.
The idea here is isolation. Reseller plans provide you with the peace of mind to know that if one of your users doesn't keep up with their site's content as actively as they should, their actions won't negatively impact the content hosted on other domains. If you and those you host in your addons are diligent webmasters, maybe this point won't have much bearing on your decision. Only you can say for sure.
3. Will these domains need SSLs?
As of this writing, SSL certificates must have a dedicated IP address to be installed. If you are hosting multiple domains on the same shared hosting package, you can still install an SSL (or purchase a dedicated IP address and install one) but you are limited to exactly one SSL on your account. If you are hosting multiple domains on the same package (and consequently the same IP), you must choose which domains gets to have the dedicated SSL.
Sub accounts of Resellers can each be placed onto separate IP addresses and, as a result, can each have their own dedicated SSL installed.
Of course, both shared accounts and Resellers' sub accounts can use the server's shared SSL free of charge. However, some clients prefer to see their domain in the URL bar when they visit https.
4. How resource intensive will these sites be (RAM, CPU, MySQL)?
We've already established that disk space and bandwidth will be no problem. But what about CPU, RAM, and MySQL resources?
It's important to be aware of the resource needs of your website. As administrators, we have to make sure all users "play nice" on the server. We can't have user X eating all of the CPU cycles computing pi to the trillionth decimal place while you are trying to serve web pages to your loyal visitors. We have to monitor the actions of all of our users and in the event someone is stepping beyond the bounds of acceptable resource consumption, we have to take action. In most cases, this entails disabling the abusive script, but in extreme cases we have to suspend the abusive user account to prevent other domains from encountering performance degradation on their sites.
If you are hosting 100 domains as addon domains, all serving nothing but static HTML pages, maybe you will stay off the radar.
But considering most sites are more complicated than static HTML, you may want to be aware of how many sites you host as addons and what content they serve. If you're hosting the latest and greatest Joomla modules, with up to date news feeds, integrated forums modules, polls, blog posts, etc your site can certainly require a degree of CPU to serve your pages. Now imagine you have 5 or 10 of these sites all hosted as addon domains. The resources these sites need to generate their content can quickly add up and before you know it you've got a friendly email from Acenet, Inc. in your inbox wondering why your user is consuming 2 of the 8 CPU cores on the server. That may be an exaggeration, but you get the idea. In the event your resource usage becomes so excessive that we have to suspend your user, now all of your sites are down instead of whichever one may be the direct cause of the spike in CPU, RAM, or MySQL consumption.
If each of these had been separate Reseller accounts, the offending account could've been suspended temporarily while we work through the cause, leaving the rest of your domains live and kicking.
The conclusion here is that you need to be aware of the needs of your sites in a general sense. Hosting unlimited domains within a shared hosting space is certainly a nice feature. For those webmasters who have multiple presences on the web, it's very convenient to be able to manage all of their personal domains from a single control panel. For those entrepreneurs who are hosting multiple domains for other individuals, the features and security associated with a Reseller plan and the inherent isolation of Linux users is a must have.

I'm not sure where to ask this but probably this section is the closest. I'm sorry if I use the wrong section.
Anyway I was wondering about checking using a reverse ip address tool which is available for free on the internet.
It seems that anyone can just check other domains which share the same IP address on a server.
However, I have a question.
Is it possible for anyone to check other domains which have different and unique IP addresses (for each domain) BUT all reside on a same server?
(meaning the person who is searching this only checks using one IP address/domain name to find out other domain names that reside on the SAME server)
Is there a 'free tool' out there that is capable of checking this?

I'm currently experiencing a problem where all domains on a server are not resolving with www. --- the domains themselves resolve fine, but the www. cnames are not resolving to the domains. This has caused quite a frustration and I'm wondering if anyone else has encountered this and if there is a quick fix to resolve it.
The domains appear to have the correct structure for the www. cname pointed to the domains so I'm guessing it must be something else.
I'm seeing this from WHM/cPanel --- the operating system is CENTos

I just wanted to know if there's any way I could speed up the process of moving my clients domains from our old server to our new server.
All my clients are currently on server1 and I want to move them all to server2.
I know I can go in and change the name servers for each domain to the new server (NS) but just wanted to know if theres a quicker way such as changing the Ip Adresses in the SOA records to point to the IP address of the new server.
Then if they're already loading off the new servers ip address, I can then change the domains name servers afterwards.

My VPS was a clean build 2 weeks ago and so far i have installed cpanel and configured everything and added accounts. I began that one of my scripts that uses gethostbyaddr($ip) was failing to resolve any of the ip's it received. I made another PHP file to test this, with this code:
PHP Code:
<?phpecho file_get_contents[url];?>
Resulting in:
Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: Name or service not known
The thing is, the VPS is resolving domains just fine

Mutiple ips for multiple domains on same server?
I have 3 ips to be used, I have used 2 for the nameserver in registrar.
I have total of 3 ips, which means, I have to place my domains via dns template to the server. Actually, I have set all my domains to a single ip, leaving the 2 ip's which I used for the nameserver to be empty (doin nothin :p)
SO, can I use 3 ips, for the 3 sites, ip1 for site1, ip2 for site2, and ip3 for site3 ? Will this make any difference in the site load and time?
I am sure they have to b set up with dns templates which I can do Wanted to know what would be the end result of my query

Since my local ISP hasn't updated yet, I'm still seeing the sites on the old server. I used a proxy (hidemyass.com) which seems to update all the time, and it said that it couldn't connect to the website (I usually use it to test a site's functionality before I can connect to the site)
What can I do to test where it's going wrong? The domains have been pointed at ns1.theplanet.com and ns2.theplanet.com already, and theplanet has created those nameserver entries for us already. I just don't want the domains to start resolving, only to find that something is broken....

I have a client that has multiple domains, is there a way of pointing multiple domains to one server? Right now, their site is on their old server, and I was wondering how they configured it? So if you type in www.mysite.com or www.mysite2.com, each show the respective domain. (i.e. www.mysite.com/aboutus.htm is the same as www.mysite2.com/aboutus.htm) I have a (DV) with (mt). I created a cname to point to www.mysite.com (where the actual NS are pointing to) is this correct?

I have 2 wordpress blogs, and I'd like a few different domains to be shared on each of them.
Using some exemples, suppose I have domains from domainA.com to domainE.com. domainA.com is my main domain and the others are addon domains.
Today Blog1 is using blog.domainA.com, and domainB.com and domainC.com use WebRedirect to blog.domainA.com. And Blog2 uses domainD.com with WebRedirect on domainE.com too.
To access a post like /2008/02/02/this-is-a-nice-post, it is available only at blog.domainA.com, and not by domains B and C. I'd like they 3 to be able to access all posts directly, without redirecting to domain A.
To do that, I suppose I'd need to do some config on cPanel. And also on wordpress, even if I replicate it over other domains it insists to redirect to its configured domain.
I was thinking on the possibility of using symbolic link (ln -s) on their folders to blog.domainA.com folder, but I don't have access to shell on SSH so I'd like to know if it would work before trying.
In a real exemple of what I want, these domains all share the same phpBB forum: forumpcs.com.br, extremepc.com.br, forumdohardware.com.br.
Do u know if symbolic link would work to share the same wordpress? And how to make wordpress stop redirecting to blog.domainA.com?
