Shared Hosting With Shell, Cron And Ping/traceroute
Jan 10, 2009
I'm looking to set up some custom monitoring stuff that ties into my existing systems, so that's why I'm not looking for established monitoring services.
I'm looking for a shared environment where I could ping and trace to my equipment, either from cron or a background daemon which I'd write in perl, python, etc.
I'd also want it located somewhere on the left coast or Texas.
Does anyone know any hosts that would meet the above?

I installed net query tool from this site
http://virtech.org/tools/
They say in order for ping and trace to work, you must chmod those executables on the server itself to 755. Is this safe or a security risk? The odd thing is, ping and trace works fine from dnsstuff.com or any other network tool site.
What is the location of those executables?

I'm looking into knownhost and they offer twice the bandwidth in their California option for the same money. Jay from known host said I should pick the one with the best ping times. I'd like to put the information here so someone might perhaps tell me what my best choice is.
I'll put the stats here and then if you could tell me which one is better (Texas vs. California) that would be great.
But if you think that the times between the two are only marginal (both real good), then could you help me decide about getting double the bandwidth for the same price.
I know nothing of course, but the two data centers look like their both giving great speeds (Texas being better though). But perhaps both speeds are great. If that's the case, can anyone tell me why someone would not take the higher bandwidth offer?
Thanks, I really appreciate any help with this!
Here is the info...
Texas (ping):
PING 65.99.213.7 (65.99.213.7) 56(84) bytes of data.
64 bytes from 65.99.213.7: icmp_seq=1 ttl=56 time=1.26 ms
64 bytes from 65.99.213.7: icmp_seq=2 ttl=56 time=1.35 ms
64 bytes from 65.99.213.7: icmp_seq=3 ttl=56 time=1.41 ms

I was wondering if anyone out there knew of any programs out there that can monitor and record ping times to various server IP's and couple output say a simple graph. There used to be this website I used that you could simply go onto there site, and register, and put in your servers ip addresses and it would output a simple graph that showed latency, loss etc for any ip you put into there system and displayed a web based mrtg type graph. I am having some troubles at one of the datacenters that I have some co-located servers at, and would like to show them how much packet loss they are having at a given time, or over say a 24 hour period.

I know there are so many similar threads related to this issue in this forum, I know but my situation is a bit different from other guys, please read the following lines,
I've got a forum with approximately 100 users concurrently, now I'm looking for a shared hosting with relatively high simultaneous MySQL connections number at least 50 and also allows Shell access to dump or restore the MySQL database. but the main problem is lots of US hostings do not host Iranian I dunno US government has problem with Iran's government but I can't understand what's my guilt in this debate?

Is it possible to schedule consecutive shell commands to be run at a given time or every certain period (like every hour)?
This is important for me as I want to schedule to run certain program and then input the following commands afterwards to do and complete the task, all automatically within the specified schedule.
One example would be connecting to an FTP. First you'd need to input the ftp command to run the ftp program, then following that, input another commands consecutively within that session (the ftp program) to do and complete the task.
I'm running KDE on CentOs4 btw.
Is it even possible to do this on cron jobs?

Not that long ago we got notification from AxisHOST that they owned ProService Hosting and our accounts will be moved to their server. New IPs, new "negotiations" about old "per lifetime" deals, etc...
[url]
Ok, fine... but what's this mail now:

If you would please update your DNS settings to NS1.ERUPT.COM and NS2.ERUPT.COM. You need to make these changes at your domain registrar. If you need any help with this please contact me.I will begin to add everyone to our billing system today. You should expect an email from Erupt.com with your login information for our billing and support system. You will also receive a new account information, this will include our server IP address and our server login information.
Your account usernames and passwords will remain the same.Anyone who has an invoice due in the next week or so I will push back a few days to give everyone some extra time.
Once again I apologize about the move, I know its a hassle but we hope its the last hassle you'll have with us!Feel free to email me with any questions!-Andrewsales @ erupt.com
We barely changed DNS settings and they sold us again? Without any notification.

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.

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.

Here is my dilemma, thanks to a thread in these forums I was directed to a hosting website called pc-core.net and I was interested in using them, because it does not appear that they oversell at all. My question is regarding the fact that they have the shared hosting for $12/month with ~5gb of disk space and 50gb of transfer. I then just looked at reseller hosting for the heck of it, and noticed i could get a reseller hosting account with 45gb storage and 450gb of bandwidth for $10/month. Even though I wont be selling hosting, or anything like that, can I use a reseller hosting account like a normal shared hosting account?...just with more space and bandwidth?

I'm new to the VPS scene, so could someone tell me the difference between VPS and say shared hosting or dedicated hosting? Actually I really like to know what a Virtual Private Server actually is.. I know shared hosting is typically a single account on a server with several hundred other accounts which is used primarily for the sole purpose of hosting websites, and I know that dedicated hosting is functionally the same as colo except that you rent the server, instead of having your own purchased server plugged into some network. So what is VPS?

Do website builders generally go with shared hosting or dedicated server? I mean, if they work on several websites would they get a dedicated server instead of shared? From what I understand through reading shared hosting is basically if you only have one website. So one with multiple websites would go with a dedicated server?

My server has been accessible in and out all day.
During these periods of inaccessibility, ping/traceroutes from multiple physical locations around the world show 50-100% packet loss.
During times when the server is accessible, ping times are anywhere from 100ms-700ms and the server does not remain accessible for very long.
I gave my provider traceroutes and pings for those times when it was inaccessible and accessible and they stated it was not on their side. It was on a hop in the middle between me (and apparently everyone else, since multiple locations around the world were used) and my server. They say it is not in their control and they cannot do anything about it.
I am reasonably sure this isn't just me or my VPS. I am on the phoenix node of PrimaryVPS.
The latest traceroute I did showed something new - a router advertisement claiming the TTL was exceeded....

I am still trying to diagnose a problem some members have on my forums, when they load a page it will load a grey screen (my background color) and stop, after 15-30 seconds+ it will finally load the page
i opened a ticket with my server co and they forwared it to the NOC, NOC said it was apache config problem, server co said it was fixed and was due to apache log reaching 2GB limit, logrotate installed
same problem still existed, opened tk with server management co, they tweaked httpd.conf and disabled logs, problem still exists
I asked 3rd management co about it, changed some settings in httpd, said it may be due to ads on the sites, i took out the ads and a stat script
problem still exists, the thing is the problem exists with some users and not others, doing speed tests to the server shows it is very quick, load is low, no i/o wait and i just installed the second GB of memory so memory is fine
this is happeneing to users on seperate forums, one using vB, one using IPB, so it is server/ hardware related, AMD barton 3000, with 2GB ram, nowehere reaching the bandwidth limit or 10mbps port speed limit
any ideas? doing tracerts to the server shows a timeout before the sites IP address, every time, but doing a tracert OUT of the server shows no time outs....
