Network Design For 3 Hosts
Jan 20, 2007
We just moved 3 1U's to a new colo center, from a single host in a managed facility. We need some advice on the best way to configure our topology. 2 Systems are Windows 2003, and 1 is Centos OS.
Each host has dual NICs, and we would like to configure 1 NIC for internal server to server traffic, and 1 NIC for the external Internet. We have a checkpoint VPN-1 firewall and several switches to work with.
Our current thinking is that the ALL NICs should be behind the firewall (for protection and for Qos control), and the external NICs need to be bound to the actual external IP address to avoid NAT issues with some of our Apps that can't handle NAT translation through the firewall (Asterisks VOIP using UDP for one).
Is it possible or recomended to do this? I have tried everything I can with our router to allow the external NICs to be bound to an external IP but still participate on the network behind the router to no avail.
Our other host had only 1 NIC bound to the external IP, and only the windows firewall turned on to provide firewall protection. We really dont have any real life experience configuring this type of setup,

We are co-located at a datacenter and host web sites, and corporate email systems, as well as host dedicated servers for customers.
We currently have two /25 internet facing subnets from our provider. We have a Watchguard X5500e 8 port gigabit firewall that supports routing as well as VLANs. We also currently own QTY4 2848 HP Gigabit switches.
We currently have each switch connected in a loop with 2 gigabit ports trunked using static LCAP. The switches are connected as follows:
A > B
B > C
C > D
D > A
Rapid STP is turned on. One thing is - is this the ideal trunking scheme?
The more important question is this. We would like to separate ips from each other using VLANing.
IE: we might have a client with 5 different IPs in one or more subnets and we would like to group them together.
We ideally do not want to break up the subnets into smaller ones as it makes it hard to reconfigure and it wastes ip addresses, as we do not have that many.

I'm designing a network that should be able to support both dedicated servers and also offer colocation (full rack and half rack). Things will be relatively small at start but the design must be able to scale. The colo area will be secured from the dedicated server area.
Right now, this is what I'm thinking:
CORE/DISTRIBUTION combined:
- Two cisco 6509's running HSRP
- Each 6509 is connected to the same two upstream ISP's via BGP (so that means 4 links in total)
- Each 6509 is connected to the access switches (described below)
- The 6509's will have a single gigabit crossconnect between them so that they can talk to each other for HSRP, iBGP, etc.
ACCESS
- Each of our racks will have an L3 switch at the top of the rack for all the servers in the rack to plug into
- there will be ~30 servers per rack
- these switches will use 4 x 1 gbit ports for trunking to the core. They will be configured in two 802.3ad link aggregation groups (ie 2 x 1gbit links per LAG group). One LAG group will connect to the first 6509, the second LAG group will connect to the second 6509.
- The default gateway on these L3 switches will be configured with the HSRP virtual IP address of the 6509's.
-spanning tree will have to be enabled to avoid loops since the two 6509's are connected directly also
QUESTIONS:
1) Each dedicated server will get 5 usable IP addresses, so I'd have to subnet my IP address space accordingly (into a bunch of /29's). This also means that I'd have to setup 1 VLAN per subnet (wich means 1 VLAN per server!). Is this a scalable design? If I have 1000 servers I'd need 1000 VLAN's! Isn't there a limit to the number of VLANS that can be created/handled by my core switches? How do larger providers do it that have thousands of servers?
2) Is this design scalable/redundant? The only single point of failure that I see is my access switch (if it dies, it could take out a rack's worth of servers). I guess I would have to live with this and would have spares on hand.
3) I'm a little confused with the interaction of BGP and HSRP. What happens, for example, if one of the links to one of the ISP's goes down on the active HSRP router? I dont want it to fail over to the inactive HSRP router, because the router is still good, its just a link that went down. Would the active HSRP router be smart enough to realize (maybe via iBGP) that the inactive HSRP router can still route to that ISP and thus just ROUTE the traffic to that inactive 6509 and then have that router send it out to the ISP? I'm assuming this traffic would travel across the 1gbit xconnect between the two 6509's so I may have to consider increasing that capacity using link aggregation aswell?
4) Which cisco switch would be good as my L3 access switch? It would have to support ~30 servers in the rack plus have at least 4x1gbit ports that I can config into two lag groups to uplink to the core.

I am comming across a few questions on how to do a setup for a network. I expect to have a redundant configuration similar to this:
________ISP1_______________ISP2
__________|(bgp)_____________|(bgp)
_______Router ---------BGP-------- Router
__________|_____\____ ___/_____|
__(bgp/ospf)|_________/_________|(bgp/ospf)
__________|___/___________ ___|
______L3 switch______________L3 switch
To this point (i hope the ascii diagram is understandable, i did my best on ASCII art), there are no problems. The problem comes when pluging in L2 switches. I would like them to be pluged to both L3 switches, but i don't see how to do this without HSRP or VRRP. The thing is L3 switches will also do VLAN's for the network, so HSRP would mean using 3 IP's for every VLAN and a terrible configuration mess.
I am not seeing the way to do this setup and attach a L2 switch to both L3 switches without using HSRP.
I just want redundancy for the case where one of the routers or L3 switches could fail.
Any light on this kind of setup?

I have almost finished designing my site and so I'm looking for a host. However, in looking for hosts I found that a lot of them were scams or were not to be trusted. There were lots of review websites that gave a top 10 listing, and the top 2 always used to be justhost and hostingmonster. Which I didn't really trust as Justhost gave me this silly thing when I tried to leave the page saying 'you can talk to a special agent to get a discount' and all that tosh.
So basically, I'm looking for a host that has a fair amount of space, preferably linux OS and preferably in the UK, and it must have MySQL support and be nice cheap one if possible, around £3.00 a month is fine.

I current have a VPS hosted with a host who rent racks from Gyron.net at Telstra Londong Hosting Center Datacenter (Docklands) and im very satisfied with the network but im looking to change hosts, so im looking to find hosting companies that also rent racks/network from Gyron.net.
So does anyone knows hosting companies that rent space/racks/network from Gyron.net?

For some time now, I've been seeing a lot of fraud activity that all seems to be linked to this fraud irc network called 'ccpower', who also like to call themselves 'ccpowah'. Obviously, they have a lot of stolen credit cards, so have a lot of resources available to build their network on stolen service, but I'm curious as to how many people have had issues with them.
Have any other hosts had issues with fraud orders being linked to these ccpower/ccpowah guys? Also, if the network link was established due to a customer's website being cracked, i'd like to hear about that as well.

Recently we bough a design from DooptNet here @ WHT - See Original Thread
However, After several weeks of having this new design and numerous amounts of time and editing & making our site look a little more respectable, We got this weird live chat conversation with a gentleman named BEN.
This was around 7am AEST & his first sentence to start off this conversation was:
Quote:
Hi Sean, my name is Ben, and I am giving you 24 hours to remove your web site template that you have stolen otherwise I will public display that you have ripped another members template for personal use without permission of the original owner
Wow that was a bit significant to me as we bought this template from DooptNet here at WHT and the thread is located above. We paid $100 AUD/USD for this and we never stole it as it was said in the starting sentence from Ben.
Ben went on to say that:
Quote:
This topics will be displayed in the largest on-line communities on the internet, these include Web Hosting Talk, Warez-BB, wjunction and so forth.
For real right?
Ben also went on further to say that many other people have fallen for this and this is all part of a Con. I am not sure if Ben is telling the truth, But I would like some word from Sean @ DooptNet and this Ben Person.
No E-mail Address was left but - Admin@webhostingtalk.com in the Live Chat.
I asked Ben where we have ripped this site from as I would like to see it, After this Ben left the chat but before hand demanded that I remove the Stolen Content within 24hrs.
Not sure what to do from here, I have contacted Sean here at WHT and are still awaiting a response.

It seems there are several ways to get a website:Build it yourself using tools software
like Dreamweaver, MS Frontpage, etcHand coded using basic text editors (or combination WYSIWYG and hand coded for w3c validation)Web builders & site studio web tools provided by web hosts Templates (both original and modified)
What I am most interested in knowing is choice most people use and for the web hosts/designers out there, do you find most people favor templates and site building software over customer design?
Personally, I have found most people favor either modified templates and custom designs and find web building tools like SiteBuilder and Site Studio too limiting.
Some people seems to still like Fantastico Deluxe though.

I have been with Hostgator for over 2 years and they have been great.
However, I host all my clients on my own hostgator account and I absolutely cannot stand hostgator's backend interface (cpanel). Trying to manage my SQL databases, 200+ e-mail addresses, etc via cpanel is tedious.
I am also interested in getting a VPS or something similiar.

I was in the market for a new dedicated server after a couple of years with my previous provider. The previous provider did nothing wrong but they were no longer competitive when it came to CPU and memory.
I moved first to geekrack. And I left them after a week and a half as they never were able to get my rDNS records setup.
I found Universal Hosts on this forum and gave them a shot. I had asked for an operating system that they didn't offer normally (Debian 64 bit) and they said that they could do it. However, when my server was setup it was 32 bit Debian instead. They apologized and had Debian 64 bit setup less than 24 hours later.
When I asked them to get rDNS records setup it took a few hours but they were setup correctly and they worked.
Universal Hosts is also a BurstNet reseller but compared to my other attempt at using a BurstNet reseller they are fantastic. While the initial config was incorrect they worked quickly to fix it and were very professional about it.
So after two weeks - so far so good. Keep up the good work UniHosts!

I am running Apache2.2, PHP5.I have been running with virtual hosts on a Windows 7 environment fine for a couple of years successfully, but have just had to move to a Windows 8 environment.It looks like Apache and PHP have installed and are working fine, but my Virtual hosts are now not being recognised. From what I can tell, it is the Windows 8 hosts file that is having a problem, as it looks as though it is now just setup to Block websites.
If I make the host file just have the one line127.0.0.1 localhost entry, then the very first Virtual Host from my apache config file will come up, but the rest are not found.If I put the usual 127.0.0.1 mywebsite.name aliasname is appears as though my website works momentarily and then is blocked..

I just design websites on the side. I've done about 10 or so and have ended up hosting them on my shared hostgator account as addon domains. I've decided to leave my current "day job" and want to try to pick up a few more web jobs in the interim.
I want to stop putting more websites in my shared account, I don't want to be a reseller and I want to be able to direct people to a host where they would get good customer service for hosting and email issues. I thought it would be nice to establish a relationship with a reseller to whom I could refer my web design clients. Ideally, it would be someone that's local (Twin Cities, MN) and I could meet in person to see if we'd work together well.
Do others do this? Does it seem to make sense to do this?
Another option would be to refer directly to hostgator. I've been happy with them but I haven't needed much in the way of customer service. Do they work well with hosting clients who don't know anything about hosting?
At some point I might want to be a reseller, but right now I want to concentrate on design and learning some new things (CMS is the next thing on my plate).

Are there any web designers/developers who offer hosting to their clients as part of their website creation package. I am toying with the idea of only creating websites for people who host with me. I currently have a colo server, but only use it for personal things. So I have no experience with the needs and demands of clients in regards to hosting. What are some of your experiences with hosting for clients? Is it worth it?

I work in a DC and am looking for a better way to deal with clients who have multiple servers hosted with us.
Heres the scenario. Client buys a server or two at the beginning, with a HW firewall or they are clustered together and require their own switch and down the road, they like what we do and want to buy more servers.
However, we've been selling other servers and the only way we would be able to accommodate them would be to run a cross connect to another cab with their new server in it. Hopefully you can see where I am going with this.
This can keep happening multiple times and with multiple clients. and eventually you can end up with spider web of cable everywhere .
My thought of doing it right but more work would be to schedule down time with a client and migrate all the HW to a new cabinet where they can grow.
Weve also been tossing around ideas like getting projected growth from clients and setting aside space for them to having dedicated cluster cabinets.
how do other DCs handle situations like this?

I run an established web design business, and currently host my client sites at resellerzoom.com
I offer hosting to my customers and the numbers are growing so I need to upgrade to something more robust, but keep the end-user support (my customers can get support directly from host, and they will attempt to operate without their branding)
Here are my requirements:
End user support
WHM/Cpanel preferrably (or plesk equivelant)
512 - 1GB ram
50 - 100GB monthly transfer
I have been looking at modvps.com as they are owned by Hosting Zoom, which also owns resellerzoom.com

Recently I stumbled along a host on here with a good rep and that uses direct admin.
Because they were very nice on the live support I signed up to see what direct admin was like.
Its very diferent from cpanel. Some parts seem to be harder to use like the phpmyadmin requires the username and password to the database you created not the control panel username and password like cpanel. Although I guess that could be a good security feature just in case some one gets into the control panel they can not get into the phpmyadmin, then again if they are smart and were able to get into the control panel they could get into ftp and look what the username and password is on the config file for the script you are using.
The bandwidth meter seems to be better in direct admin although I think its acting up for me as its putting yesterdays bandwidth on todays. I was told by the host that it updates every 2 hours and at first it did but now its gone to every day. Oh and unlike cpanel this bandwidth meter includes bandwith used by the control panel.
Niether one from what I can tell counts sftp though at least for the hosts I have right now.

i would just like to vocalise my utter disbelief at how incompetent and dishonest Absolute Design Barnsley aka Smart Merchant aka Absolutewebdesign.co.uk have been.
Our company signed up just over a year ago to their Absolute Design Smart Merchant shopping cart website system.
To overview, this is a pay-monthly service where they host the site and we add products to the CMS style website that Absolute Design have produced.
Being a small family business we opted for this kind of pay monthly service as it would (we hoped) give us some level of support from Absolute Design Barnsley to help with the running of the site.
At first they were helpful at getting the site setup initially but months down the line and after phonecalls or online chats with Absolute Design , the result has been no action being taken as requested.
Simple things like removing the option for other currencies... I phoned in August of 2008 and was asked to email the request to Absolute Design Barnsley , which i did. Did the other currencies get removed? Nope! I phoned and emailed many times.
This year due to the economic climate we have had many price changes to do, so i phoned Absolute Design Barnsley and asked for a holding page to be put up while i changed all the prices.
I was told this would be done within the hour.
I had my doubts that this would actually happen due to past experience, and indeed a WEEK later and the holding page STILL was not up.
During this week we had several people try and buy things at the old prices and we had to cancel orders. This is obviously frustrating for us and the customers.
Due to Absolute Design 's Smart Merchant poor system i since found out i was unable to 'turn off' the shop in any way except for basically deleting the entire payment gateway setup.
Products were also still viewable at old prices via google, even if i disabled them in the CMS itself. BAD Smart Merchant !
Also in this time i managed to decide and almost fully populate a new website for our shop, it seem's Absolute Design Barnsley cannot even produce a holding page in that same space of time.
Now, you may think why didnt i just leave? Well, after that week i rang up and asked to cancel, i was asked why and i CALMLY stated my reasons, which were basically poor support.
This resulted in Andy Clegg from Absolute Design Barnsley saying to email my request to leave and he slammed down the phone.
I emailed my request to change our Domain IPS tag and contact details and within a few minutes our website had been deleted BUT Absolute Design Barnsley decided to delete the IPSTAG for the domain, basically rendering the domain useless, including our email which we use on a daily basis.
I spoke Absolute Design again on the webchat (on a friday) and asked them to change the IPStag again, they said ok, but it probably wont get done till Monday.
I was obviously doubtful as it didnt take them long to delete the IPSTAG....
Monday comes and Absolute Design still haven't changed the IPSTAG. We are shut on mondays so i rang on Tuesday and spoke to Craig. He seemed more reasonable and said he would change it shortly. Several hours later and Absolute Design Barnsley still had'nt changed our IPSTAG and were still basically holding our domain hostage.
I ring up AGAIN, speak to craig, he says hold on for a moment, about a minute later they just hung up the phone again. I ring once more and noone answers...
Instead of swift switchover to the new site, Absolute Design Barnsley have forced us to take action with Nominet to recover our domain.
This just seems ridiculous, I'm guessing Absolute Design Barnsley must be losing alot of customers but to act the way they have is just childish.
What is the point of causing so much agro just because someone wants to cancel?
I hope this post reaches anyone else who is considering taking up services with Absolute Design Barnsley aka Absolute Web Design aka Absolute Web Hosting aka Absolute Shopping Cart aka Smart Merchant and urge you to think twice!

I have a few questions about hosts.allow
1) There are 2 IPs in this file. I did not put them there. This is a dedicated machine. The IPs go to a Canadian hosting company. I am not in Canada and those are not my IPs.
2) Does my provider have the right to add IPs to this file without my consent?
3) I have already commented them out, of course, but I am concerned.

As some of you may know I have about 4 different webhosts.
the problem is thats to many and I want to maybe cut it down to 2 but not sure which 2 and thats my delema or jam.
Downtownhost is one of the 4 hosts and I have been with them for over 2 years now and its great and support it top notch. So would hate to leave them.
Everity is another one and they are great as well and very honest, which still impresses me today and I have not yet been with them a year but it will be this December. They were able to run my biggest site with out any issues and that was nice then again so was downtownhost able to well to a point until the space the site was using got to big for downtownhost which is why I got everity in the first place.
Hostsimplex is a new one I got to see what directadmin is like and wow direct admin is awesome and almost I want to move all my site to this host. They are also very nice/ friendly and support is also honest and gee a few times while opening up the live support for a question or a problem figiruing some thign out in direct admin I have gotten into long friendly convos with them. Kind of feel bad about that though as I would hate to take the support staff away from other customers. I do like also how they have free remote back up, which is nice but I still will make my own back ups locally just in case. Any way this host is still new for me so I am not sure how good or bad they are but so far its good.
The forth one is liquid webs as as of right now my main and largest site it on it. This hosting is not one I own but a friend/client. I am not even paying for it which is nice. How ever I have little to no support as I have to rely on my friend and he is not always on when I have an issue. Do to that this might be the first one I drop.
Although it it rare that I have issues and I do not have to worry about the cpu ussage, bandwitdth, diskspace because he said I could use what ever i want. He also said the server has a 500gb hard drive and not even 10% is being used.
Any way thats the issue I am having so which do you think I should drop or should I just keep them all as I do have an active site on each one.
