Real World Testing

Feb 25, 2007

We have recently moved to a new datacenter and I was wondering if anyone on these forums could provide their experiences with "real-world" testing.

Upon move-in, we had a few issues. Obviously now the executives in the organization I work for are looking for justification for moving to the new colo.

software, or an online service that will stress test our current setup? Obviously I have MRTG, Awstats, and a few other of the most well known polling packages installed and working correctly, but what does everyone else use for stress testing?

Does Mod_cache Use Real Disk Space Or Real Memory To Locate "cache"?

May 18, 2009

does mod_cache use real disk space or real memory to locate "cache"? I mean if i use mod_cache, does my vps/server will use more disk space/memory?


mod_cache implements an RFC 2616 compliant HTTP content cache that can be used to cache either local or proxied content. mod_cache requires the services of one or more storage management modules. Two storage management modules are included in the base Apache distribution:

FastCGI Hello World Test?

Jun 20, 2009

Just moved to a 1and1 managed server in which FastCGI is enabled.

But I'm having problems getting Movable Type to run under fastcgi - which has never been a problem before, even on shared hosts.

Is there a 'hello world'-type test for fastcgi - so I can check if it is enabled?

Host Once - Where In The World Is My Server?

Sep 30, 2008

I have been running a dedicated server for years, first with Carolina Online, who then sold it to HostOnce.

Today at around 6PM my server, that was working fine and I was actively working on all day, suddenly disappears off the Internet.

I go to Host Once's ticket system, and they have a message up that they moved their servers from NC to NJ, that all the servers were upgraded to Windows 2003, and that they would be very busy with the migration, don't submit multiple tickets. (Host Once seems to mostly have reseller hosting accounts, not many dedicated servers.)

I start pinging IP addresses and everything in my server's IP block is gone (the furthest a tracert goes is - everything under that is gone.)

This is bad.

I'm worried that they may have bought new boxes in NJ for their reseller accounts, transferred up the data, and abandoned the old boxes in NC ... is this something they might do?

Also worried that the block of IPs their old servers were on may have somehow been reassigned... can this happen?

In any case, waiting to hear back on my ticket but looking for advice. Does anyone know the datacenter Carolina Online / Host Once used in Lumberton, NC? Want to start tracking it down if my box may have been left behind.... Any other insight on what in the world they might be doing / what happenned here?

Test Dns Lookups From Around The World

I am trying to debug a dns problem.

What I need is for you to do a dns lookup and report:

1) the address that was returned, the last octect will do.

2) the area of the world you queried from

The answers *will* vary because the dns server is geolocation enabled. Or, at least they *should* vary. But, someone claims its buggered.

The host name to lookup is:

100Mbit+ Unmetered - Anywhere In The World

Jun 22, 2008

Can someone give me a good list of providers like fdc, ovh, etc.

Bandwidth quality not much of an issue, quantity means more than quality to us, cogent only networks are even acceptable

We need more than one, as we need servers all over the world.

Edit: 100Mbit with unlimited or VERY high bandwith limits minimum.

Edit 2: Looking for something similar to fdc and ovh in price if possible. Going over 500/mo is pushing the budget on these, although specs do need to be taken into consideration.

Apache :: How To Access Server From Outside World

Aug 16, 2014

I have a local network with modem, router, and several computers either Cat5 to router or via wireless. Router is Cisco Linksys E4200. The internal IP for this router would be of the computers has Ubuntu Server 14.04 (32-bit) and Apache 2 installed, and this is hardwired (Cat5) to the router. This computer also has a STATIC IP address that we will call my Windows 7 Ultimate computer, I can open a browser and type "" and the Apache 2 Ubuntu Default Page will pop up telling me that "It works!".

I have the Apache server working since I can access from within my LAN.My problem is to get it to show me the same "It Works!" when I try to access from the Internet.I got my 'external IP' address by simply going to, and I can also see it from within my router settings.

The next thing I did was to setup Port Forwarding inside the router, to point say 50505 to I've tried lots of port numbers.I cannot see my Apache 2 Default page by typing in my browser "", for example. This assumes is my external IP and 50505 is the port I am forwarding.

I've tried disabling the IP4 firewall within the router, and even the "anonymous" filter request setting.I can find my web-server via browser in-house, but I cannot access from my external IP as if I were at a different location.

Data Centre List - World Wide

Jul 17, 2007

I have been playing with the idea now for a while to create a site that will list all the data centres (datacenters for you americans) in the world.

Obviously I do not have the definitive list, so it would be community based, where users can add DC's and reviews can be written for it...


1. Is there a website doing this already?

2. Would it be used...?

PC World Article: Reduce Fire Risk - Remove Oxygen [merged]

I did a quick search on this and could not see it as already being posted

It seems quite a clever but simple idea - remove a lot of the oxygen from the air to help reduce the risk of fire. What do those of you operating your own facilities make of this? Is anyone already doing this?

VPS Is It As Real As It Seems

Nov 25, 2007

How do you really know, you get what you pay for

example I pay for half a dedi (1GB ram 50% CPU)

I see the full server ram in TOP 4gb most in use, who uses this?

I see high loads as well even tho it aint my bit

All I know is I could be on a server with more then 1 other, maybe 4 others etc..

Can any of the info be tempered with, false reading in TOP / beancounters

I was going to move to full dedi, but only 40GB space makes me think, as most dedi have far mor space

Migration Testing

Apr 21, 2009

I am migrating my website to Hostgator, and before I change the DNS entries, I want to make sure that everything displays properly. To do this, I have added an entry into my /etc/hosts file pointing the domain to the new host. If I then ping the domain, the reply comes from the correct IP address. However, if I try to view the website, it is still served by the old host.

I thought it might be a caching issue, but I have checked with wireshark and using curl, and it is definitely connecting to the new IP address, but the server that is returning the pages is still the old one. I've contacted hostgator support, but when they make the changes to their hosts file, it loads correctly. Is this a local problem (my system), or something with their server configuration?

Testing New Webserver

Nov 4, 2009

I am looking for some decent tools to test a web server that can run large scale web sites running Windows and Linux.

I am more interested in the underlying hardware at this point to see if the servers them selves are capable of withstanding the loads without choking.

I am most interested in Disk testing and Network testing but the server but of course the server as a whole is important to since cpu and memory bottle neck can affect everything.

VPS For Software Testing

Apr 19, 2009

I am currently developing a piece of software that will act as an all purpose control panel for a specific niche. I have coded the vast majority of the control panel already, and want to purchase a cheap (under $25/mo) VPS to test the installation and performance of the control panel.

As a result of me testing various configurations the main feature I am looking for is free (or very cheap) OS reloads.

I want to be working under a CentOS environment, and have a decent amount of CPU that I can use. Disk space and bandwidth are really not an issue, as I am simply testing using this VPS to test the software I am developing.

Testing Mod_Evasive

Apr 2, 2007

I have 2 questions here.

1. I have installed mod_evasive version 1.10.1 on a Cent OS 4.4 server.

I'm using the script that comes with mod_evasive to test the configuration and when running the script from the same server mod_Evasive is installed. The mod_evasive is able to detect the intrusion and block the IP of the server.

If I use the same script from an external server the requests come in and are viewable in the access log but mod_evasive doesnt block the IP of the external server. Probably is not blocing the ip of the external server because of latency.

Is there a way to modify the script to make it more agressive and get results when testing from an external server?

Here I'm pasting the code of the script:


# small script to test mod_dosevasive's effectiveness

use IO::Socket;
use strict;

for(0..100) {
my($SOCKET) = new IO::Socket::INET( Proto => "tcp",
PeerAddr=> "test.domain.tld:80");
if (! defined $SOCKET) { die $!; }
print $SOCKET "GET /?$_ HTTP/1.0

$response = <$SOCKET>;
print $response;

2. Also, I have sendmail installed and on the mod_evasive config I have email address specified on DOSEmailNotify. When testing from the internal server with the script the server is able to block the ip, put in the hash table but it never sends an email to my email address.

Testing A Certificate

I've installed a certificate in my server that's certified by a CA, but I want to see what happens when that CA is no longer listed as trusted. In Internet Explorer I click Advanced and de-select "Server Authentication" for my CA. When I go to my site, though, I don't see the usual untrusted warning come up. How do you test this?

what's the difference between the certification authority and publisher sections in Internet Explorer?

Where Have All The REAL Hosts Gone

Mar 22, 2008

My company has 20+ clients ranging from small single-person businesses to medium-sized corporations. I've been hoping to eventually consolidate them under one hosting company.

Despite bad things I'd read, I THOUGHT I'd found a good home in Bluehost. Until yesterday. I'll leave out the story as it would be a short novel, but I'll just say that they proved to me that they are not a suitable host for an important corporate client, nor do they have any desire to be.

It's obvious to me that I need to stop looking at these discount hosting companies. But while my larger clients may be happy to pay a decent amount of money for reliable service and server admins who are willing to tweak a server setting for them on occasion, I also need to be able to provide a reliable host for my smaller clients who may be used to paying $6.95/month for hosting and don't want to go too much higher than that.

I see ad after ad for hosting companies, but that tells me nothing about how good a host really is. Asking on forums, searching the internet, you'll find everything from how great a host is to how they're the worst host on the internet. But you all know this.

Years back when I was first searching for hosting, I found a site that tracked hundreds of hosts and compared their pricing, services, support, uptime, etc. Are there any reputable sites like that these days?

Ideally, I'd like to find a host that offers it all - packages suitable for everything from small clients with tight budgets to larger corporations willing to spend what it takes for good service. I need extremely reliable hosting with tech support who will do whatever it takes to quickly solve problems and keep sites working properly. (Edited to add: 24 hour phone support is an absolute requirement, and 24 hour chat support is highly preferred along with that.) Does such a creature exist? If not, I'd be happy with one GOOD discount host and one GOOD corporate host. If there are any hosts out there who are well-known for their excellent service, I sure haven't found them. I'm very much open to suggestions.

I always tell my clients that my job isn't finished until they are 100% happy with the service I give them, and I want to be able to provide them with hosting where they will be treated just as well.
