How To Track A Hosting Proivder
Jun 27, 2009
I'd like to know, is there any way to know about hosting provider, if we have only ip address of the server. i.e.
66.63.181.74 - this is the ip address of my website server, how can i trace the service provider who is giving this hosting service?

My server currently has some problems with DNS/mail, which i can't seem to fix myself. My colocation host offered to help me by giving him root access, but i don't know him very well yet. Is there some kind of script/logtool so i can track everything he did on the server? I don't want him snooping around through my webfiles and databases...

Can anyone please tell me how dangerous in fact Apache's TRACE and TRACK functions?
I have read common explanation but would disabling TRACK and TRACE improve my server's ability to fight cross site scripting and similar attacks and make it more secure?

I'm small hosting provider. On one dedicated server I have around 100 cPanel accounts.
That server is under constant, although not powerful DoS attack.
Since my company domain is not targeted on another server I believe that it is not me but one of my customers that attack is against.
Is there a way, tool, service provider than can help me pin down which account is being hit?
All accounts are on server main shared IP.
Would spreading them on another IPs help? Or would I still see attacks only on main shared IP?

I have a few shred hosting servers I run. One of them keeps getting listed on CBL. It is very frustrating. Does anyone have an tools, tips, or tricks on finding the compromised?
So far I have confirmed that a script is using PHP to send mail out bypassing the MTA. It is faking the HELO and impersonating a well known ISP.
I used a combination of tshark and netstat. tshark can show me the HELO and EHLO. When I see the wrong entry I cross check that with netstat to see what. So Netstat only shows that it was PHP not the script path.
Here are the commands I'm running:
Code:
nohup netstat -c -p -n -e | grep -i ":25" > /var/log/monitor/netstat-smtp.log &
nohup tshark -f "port 25 and src host XX.XX.XX.XX" > /var/log/monitor/tshark-smtp.log &
Then I grep for what I'm looking for:
grep -i "HELO" /var/log/monitor/tshark-smtp.log
Is there a way to get Netstat to show the script path or complete command that is establishing the connection? Currently these scripts are eating up memory to a point that other process or getting killed off.
I also tried to force all mail through the MTA, but When I enable SMTP_BLOCK in my firewall config I get and error:
*WARNING* Cannot use SMTP_BLOCK on this VPS as the Monolithic kernel does not support the iptables module ipt_owner - SMTP_BLOCK disabled.
If there is a better way I'm game. Maybe some IDS that can tell me more of what is going on with the server?

I am currently developing a web application on a WAMP server. Once complete my client will have some in-house "programmers" make changes to the code as they are needed.
My client wants to track all changes made to the source files (ie- who made the change, when it was made, what files were modified, and what specific lines were added/removed/modified). Also, the program must run on the server and not the programmers computers.
I've searched high and low and only found a couple programs that scratch the surface of what they want.

how exactly email works. For example, I set my mx record to google apps in order to use google mail with my own domain. Thing is, I can sent from google mail now with my domain email address but cannot send. Furthermore, login to my website email bij www.domain.com/webmail is possible but receiving is impossible and even sending email from that place will not work.
Thinking about it it seems that email is lost
google can send but not receive
from my domain webmail i cannot receive nor send.

I've done plenty of searching on DDoS attacks and from what I've found so far it seems that it's "very difficult" track down the person(s) responsible for the attack.
My question is this - could someone actually do it if they were qualified enough? Would a hacker who is well versed in the techniques used be able to find the person(s)? Or is it just simply impossible sometimes?

I'm working on setting something up for monitoring my bandwidth/traffic on multiple interfaces. I have setup interface aliases so I have eth0, eth0:0, eth0:1 and the issue I'm running into is that it seems snmp cannot tell the diff between the aliased interfaces. I've found references in the cacti forums of using ipchains rules to track the bandwidth, but I've not found a good howto that explains what I need to get going on this.
Any clues/hints?

How can I track down where these messages are originating from? Or perhaps I am reading my LogWatch file incorrectly?

I'm wondering if theres anything I can install on the server that will either filter or track outgoing spam. I don't want to limit the number of emails sent per hour or anything, I just want to be able to maybe search through some flagged emails or something. Or if they send the exact same email more than x times it can disable their account... I'm not sure

Often when it comes to choosing or recommending a host, I tend to favor the ones that are larger, and more established such as Hotgator or Downtown Host. But in some other threads, I have seen plenty of people swear by some smaller hosts. Are there some good examples of small hosts that have been around for 3 or more years and have a great reputation?

I know it's not specifically a plesk issue, but as I use plesk to resell webs and many users install (manually) wordpress, I thought I'll ask around.I would like to know if this can be done with a single sql select or if I would have to use a script to do this:
- track all mysql databases on my server
- find the proper table in each database (as the prefix can be customized, the start of the table name will probably never be the same in two WP installations)
- find the proper field in that table and check the WP version and administrator email
and then what I will do is send an email to those adresses advising them to update WP

I'm trying to find at least three web hosting companies to choose from to host a Joomla websites on a shared server. Would consider dedicated if the deal was right. I have a friend of mine who wants to create a church website, and is looking for the best deal. I use Netfirms which I have never had an issue with, but I didn't want to be bias, and would like give him other options to choose from.
Is there a good WebHosting Review site, I could check out, or maybe someone could recommend their top three. I reading threw the forums here and I noticed there are not that many complaints with Hostgator. Again, I just want to see if there was anything out there better.

Lets say you're a customer looking for web hosting, but do have technical experience - you know, you develop your own websites, you've had experience in this sort of thing before.
What if you came across a provider who seemed to offer a good service, they're high quality, they can host your website on their brilliant setup etc... but they do not provide any e-mail accounts with your hosting?
We're developing our own shared hosting setup, our own control panel too. Regardless of the control panel though, we wouldn't feel comfortable hosting peoples e-mail. We have plenty of experience in every other aspect of general shared hosting - but not looking after e-mail accounts nor the associated software.
To be honest I don't think that many shared hosting providers truely handle e-mail properly, and that job should really be left to the professionals.
We could of course guide customers or potential customers on why we won't offer e-mail accounts (i.e. not wanting to offer something we know we can't provide to a high enough standard) and instruct them on how to setup e-mail with another provider (such as Google, who will do this for free with limitations).
The alternative to the above is that we mask in a third party to look after e-mail, i.e. resell someone elses e-mail services as part of our hosting packages. The third party would require API access to setup/remove accounts..
What do you think? Are we just acting stupid trying to provide web hosting without e-mail hosting included? I noticed a while back Dreamhost encouraged their customers to use an alternative e-mail provider!

I have about 5 sites all hosted on my same hosting account. One of those domains is attached to the hosting account. I place my other domains in a folder of a sub-directory of my main domain. This has been working fine, up until today when i noticed a weird error. I give you a little example of how my sites are setup
my main domain:
www.maindomain.com
My other sites hosted in a sub-directory of my main domain:
www.maindomain.com/sites/site2/
www.maindomain.com/sites/site3/
How my other sites appear on the web:
www.site2.com
www.site3.com
This works fine for every page until i go to www.site2.com/index.php
It redirects to www.maindomain.com/sites/site2/index.php for some reason

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 am developing a website for a client of mine (the client is a close friend and know's that he is getting a newbie). This site will be larger (project wise) than anything that I have ever done (everything I have done in the past has been FrontPage). We will be using several third party applications that need to run on the server as well as our own custom developed applications. We do not yet know how much access to the server's deeper structures we will need for all of the applications that we want loaded on our server to run. Things we have in mind: oscommerce, mysql, php5, apache, linux, vbulletin, blogger, phpbb, adserver, ect... Would these things run ok on a shared host and would I have full authority to configure them without needing full access to the server? Or will I need access to the entire server (dedicated server) in order to have full customization capabilities? I guess all I am trying to figure out at this point is will shared hosting for a large project limit our abilities to use 3rd party apps, or do most 3rd party application designers build their stuff to work in a shared hosting environment anyway? If we need to get a dedicated server we will, but if we can get away with shared hosting for a while (especially during development when the site will not be generating revenue) it would be nice to avoid the price of a dedicated server. Many thanks for your comments, insight, and expertise! Also, if anyone can sight some common scenarios that may require a dedicated server over a shared hosting plan, that may help me to understand what the limitations of a shared hosting plan vs. a deicated or virtual dedicated server are.
