trying to understand the colocation business model (for webhosting).
Am I right in assuming that following business model:
1. Rent a portion (or full) rack from datacenter, e.g. calpop.com
2. Buy servers and get them shipped to datacenter
3. For unmanaged servers, typically most support will be limited to reboots, reinstall of OS/control panel, and server hardware issues - correct?
4. Provide basic support, or sign-up with companies like bobcare.com to provide support to clients who order server
One-time cost (for 1-3 years): Cost of dedicated server hardware
Ongoing monthly costs: rack rental + outsourced support (optional)
...plus marketing costs....
Please let me know if I missed something or overlooked details...
I have decided to finally remove all my servers rented from provider to provider to one single place.
I want to manage everything, so basically route the traffic (at this time without BGP or OSPF), my current average of traffic for all servers together would be about 15 Mbit/s with top at 35-45 Mbit/s.
I want to buy a cheap router (no computer router), I'd like to buy a chassis with very extensible and upgradable router, so I can start with a basic card and later use BGP (and maybe OSPF) and have ability to push from 30 Mbit/s (to over 1000 Mbit/s by upgrading cards and memory).
So, which (refurbished or not) chassis can I buy ? Which card would you setup with it ?
The important is really the ability to start with low cost configuration and go up to very high rates without having to change all (of course once I will be average over...).
its seems thats the problem keep didn't fix it when i try to install the textimage plugin for the wordpress ......
PHP Code:
You don't seem to have the PHP gd module installed. This is required in order to use the TextImage plugin. For example, in CentOS 4 the command 'yum install php-gd' will install the necessary components.
so here the result ....
PHP Code:

and the plug did not work yet with that message !!

I have 2 dedicated servers to host several websites at this moment. Each server hosts several website, include both files and database (Apache, PHP, Mysql). And I think that this is not a good model.
I intend to re-organize my servers to have one server for web applications (Apache and PHP) and one server for databases (Mysql). In this case, the servers could be better optimized.
I used so far Nortel switches like Nortel 4550T-PWR, recently few of them died and since they have only 1 year of warranty i'm looking into other options.
To Nortel is this Cisco comparable model Catalyst 3750 (p/n: WS-C3750-48TS-S) or this Catalyst 3560 48 10/100 + 4 SFP IPB Image(p/n: WS-C3560-48TS-S) ? If is some other model please let me know, and i got around 20 nortel switches 2xxx, 4xxx and 5xxx series and at at least once a year one dies is that normal? They are properly installed in server rooms so there is no overheat issue.
And how much warranty Cisco gives on their switches which are comparable to 4xxx and 5xxx series of Nortel.
if anyone knows of any shared hosting company that supports the out-of-the-box Model-View-Controller (MVC) asp.net template and which version (the latest at the moment is Preview 5).
Moreover, does it support .net 3.5 with sp1, IIS7, SQL 2005 and ajax control tookit?
I'm running a fresh install of Plesk 12 on Ubuntu. I've used the migration manager to import domains and accounts from another (older) installation. Everything worked well.
After the process, Plesk suggested the "Complete Switching to the new Plesk business model". After switching, half of the Domains didn't show up anymore (not in Subscribtions, nor in a Customer Account) and the Domains page was completely blank. But if I check the page "Traffic Usage By Domains", the Domains still show up and they are still in the vhosts folder and they are still accessible.
So I guess the Domains are still in the database, they just lost the connection to a subscription or customer. How can I restore this connection?
I've asked sales a few times but they don't seem to know...what counts as a "website?" In PPA as a test we set up two subscriptions and one mail-only secondary domain on one of them. The Services/Websites tab lists all three, but only two are marked as Website under Hosting Type while the third is marked No Hosting. Does that count as two websites for license purposes, or three?
I'm trying to plan for multiple domains, subdomains, etc.
Recently I've tested the usage of domain keys on my plesk 12 server. The feature works without problems. I'm wondering however if it's possible to activate the domain keys by a service plan or subscription model. If not, for all my domains (65) I've to activate them manually and for each domain iIll create in the future I have to activate it too.
I want to use scp to backup files, however I find most tutorials confusing as to which computer is the remote and the local. Is the local the one you are logged into via ssh command, or the computer from which you logged into ssh.
Lets say I am on my Windows computer. I open up putty, and login to the ssh connection of a remote linux computer. What scp command do I enter into the ssh terminal to copy a file from D:ackup of the windows computer to /home/backup of the linux computer?
I am getting ready to install APF, I have read multiple articles, but am still confused with the following parameters and what needs to be included in each:
having my own dedicated server. I have apf installed and I wanted to see how it blocked IPs so I had a friend, whoes IP I knew, help me. I added his IP to the deny_hosts.rules, thinking that would block him from my server, but it did not. Now, mind you, the way I added his IP was to simply use an editor and add his IP to the bottom of the list. Then I got to thinking, does teh apf only load the rules every so often? If so, how can I tell when or how often the rules load? ALso, do I need to add an IP using apr -d IPNUMBER in order for the apf to recognize it? I'd appreciate some info on how the apf works and how I can add IPs myself that I want to add and be sure that they are being blocked.
I am going to place my first physical server to a server room. I wish to use it also as an nameserver for my domains and I am missing some basic principle there. I can probably configure BIND etc, but how will the servers upper in the hierarchy learn that this is a nameserver for certain domains? To start with, I have several empty domains (they are not hosted and so far using nameservers of a big company).
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....
I have a basic understanding of their role and how they work in general (mapping domain names to ip addresses).
I'll start with my setup/scenario: Plesk - (dedicated company server - serving parent site via WHMCS) ResellerClub - (domain registrar) Cpanel/WHM - (shared server)
1. What would be the recommendation for a new hosting provider when it comes to name server(s)?
2. Do most who have limited resources use the BIND service on each WHM shared server itself? So if you have umpteen shared servers you would have umpteen name servers, as well?
2a. If so is it preferred/recommended to ultimately use completely separate/dedicated server(s) for DNS services for all shared servers? What is common?
3. If using the WHM shared server itself is the common practice, what are its pros and cons?
For the last week or two my VPS keeps getting added to blacklists.
Yesterday I noticed that a website on the server was forward mail from a contact form to the clients AOL account, obviously scripts were completing the form on the website and that was being sent to AOL, who would of obviously blacklisted the IP.
I've stopped that now, but we're still getting black listed. I've had my VPS provider get exim to record the path that sent the e-mail, and there are no scripts on the server sending out mails that I should be worried about.
Some questions to help me.
How can you identify an outgoing e-mail? is it by the character '=>'? If so, is it normal for there to be e-mails being sent out: 2007-08-23 19:04:10 1IOH2K-00038j-Jg => /dev/null <shaun[at]sr8.co.uk> F=<aaron_straubegnvu[at]yahoo.com> R=central_filter T=**bypassed** S=0 QT=6s DT=0s 2007-08-23 19:04:10 1IOH2K-00038j-Jg Completed QT=6s
I'm puzzled as to why the server keeps being blacklisted, when I can't really see any problems in the log file?
The CBL website (which blacklisted us) says we were added at around 19:00GMT, so I've checked the logs for that time and can't really find much.
On the server there is one account with an autoresponder set as that person is away on holiday.
I recently went from dedicated to Dotster VPS to cut down on price and also because I do not have as many of clients I once had.
I chose their cPanel Premium [url]
Soon after I realized via the Virtuozzo Panel, that I have limits on everything . I was pretty upset that none of these limits were posted anywhere on Dotsters site and its a surprise not welcomed.
I want to post some images so maybe you can tell me if their limits are reasonable or if they are way off.
[url]
I had them actually raise my diskinodes from 400/500k to 600/700k and also my quotaugidlimit from 100 to 200.
For some reason I have 162 ugid's but i have only restored 23 or so accounts on this server, with no other special things running besides the standards. Shouldn't I be around under 100 ugid's?
So my main problems that I have is the folowing limits:
diskinodes: I have only 35 gigs used of the 50 allocated, their initial quota of 500,000 seemed low. now they bumped be to 700,000 and i'm almost there.
quotaugidlimit: for only having 23 accounts it's crazy to believe that I had to have their initial limit raise to 200. I have noticed a lot more users like #2121, #13232, #124312 and so on compaired to my dedicated server. My dedicated had about 5, this VPS shows about 30 or so.
kmemsize: their limit is 18,022,400 bytes, which I always seem to be reaching.
privvmpages: hard limit is 292,912 and i'm usually exceeding this one.
Here is a screenshot of my QoS: [url]
Also, I noticed once I reach/exceed limits, the first things to be shutdown is my webmail and cpanel and so on, but the sites stay up Is there a way of setting up which resources are shut down in what order? To have mail up is the biggest request. I rather have ftp and cpanel down first.
I am really not happy with what is going on and gaining some user feedback would be great. I really wish Dotster had a complete breakdown of limits, before I bought.
I want to understand the mechanics of a DDOS attack. I have been doing a lot of reading about them this weekend.
The way I am understanding it, a DDOS attack is done at the network level. It may be requesting that pages from a given website, or websites, are served up, but it basically will effect the entire network. So if 'page display' requests are made to a website(s) that is hosted at ABC Hosting (example only), to the tune of 15GBs then I have to assume that the network will be terribly degraded. If that is so, wouldn't other servers also get taken out?
I believe the architecture of the internet is something like this (example only):
I use Munin to monitor the health of our servers, I can tell by looking at the graphs there's nothing to worry about, however, I'm struggling to baseline acceptable performance.what would be classed as 'normal' output for some of the more relevant munin graphs.
I've been looking at the Apache* modules and this is the output from one of our servers:
average of: 300 accesses per minute, 6 busy servers and 4.10MB a minute volume
max of: 1400 accesses per minute, 81 busy servers and 51MB a minute volume
This is a dedicated box running one site.
We have another box that is running approximately 30 sites
average of: 30 accesses per minute, 1 busy server and a 500K a minute volume
max of: 322 accesses per minute, 11 busy servers and a 4MB a minute volume.
These servers are pretty much the same spec, dual core 64Bit, 4GB of ram, two SATA disks in RAID1.
I'd like to seek help on how to read eximlog file. I saw the below inside eximlog. I'm wondering now because realemail@domain.com does not exist on this user emailaddress when I browse his cpanel. Now who is sending it? the only correct info is the pixelxl which is the user.
I use my dedicated server to host my own large site and web forum, and I want to stop hosting my own email server so I don't have to manage it. I want to use Google Apps for Your Domain to manage my email, pointing my MX records to Google. However, I am not clear on how this will effect PHP scripts sending email on my server. My vBulletin installation sends 1,000+ email notifications every day, which far exceeds Google's 500/day sending limit, so I obviously can't use their SMTP servers. If I'm sending mail from my own server via PHP, though, and my MX records point to Google's, how can vBulletin send an email from an address at my domain? I've been reading up on how email works, but I just can't seem to figure out how this works...
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...

I see that there are some connections from my server to some remote mySQL server, and I am curios to know which script is running them. (192.168.30.98:40493 207.45.xxx.xx:3306 5339/httpd)
I try through lsof but it is not that it points directly to the website running this connection.
I've been working with Linux lately and been wondering how Linux (Fedora/CentOS) manages its memory usage efficiency.
What I've been noticing is, Linux uses quite a lot of memory for just a single application. For example, Firefox-bin uses like around 100mb of memory.
At the same time around, when KDE/Desktop Environment aren't installed, Linux uses very small memory for non-GUI applications, such as those of hosting-related services.
Isn't using 100mb of memory for a browser application a bit too much? Is the memory information under "top" command represents the physical memory available? Is there any difference in performance when in physical server compared to virtual server (virtuozzo for example)?
I don't know anything about CPU. According to BlueHost, they offer 40 seconds of CPU processing within a 60 second period. Our sites are mainly forums and blogs. For the next year, at most, we'll have 200 unique users a day, we're guessing. Do you think running something like WordPress or forum software would be too much with BlueHost's restrictions? We will focus on 10 sites during this time, so it'll be about 2,000 unique visitors a day across our entire account.
