How To Use 2 Windows VPSs For Higher Reliability
Oct 3, 2007
In order to increase the reliability of a audio streaming service I am thinking to take the action I describe below.
1. Buy two Windows VPSs with WMS installed.
2. Register a domain name (i.e audiostream.com) with 4 nameservers: ns1.ip1_vps1, ns2.ip2_vps1, ns3.ip1_vps2, ns4.ip2_vps2.
3. Create all publishing points (streams) on both servers.
Normaly VPS1 should serve all clients. In case VPS1 goes down, VPS2 should jump in and serve all clients-connections. As soon as VPS1 becomes available (ns1 & ns2 start responding again), VPS1 starts serving all new connections.
Load balancing or any other kind of advanced load, traffic, etc management is not important.
Then we have the following cases:
1. VPS1 is down , which means that VPS2 should take charge.
2. VPS1 is up (ns, http, ftp services), but WMS1 is down (crashed). Means that the playlist (asx) file should be built so that it also includes the IP, port & publishing points of VPS2. This should be done because ns1 & ns2 will answer without any problem, but WMS1 will be crashed and won't serve any media connections, thus ASX will look for the next available stream in the playlist.
Do you think that the above is possible. Is this gonna work?

Why are there many people setting their TTL to higher values rather than lower ones? By setting it lower, won't it propagate faster?

Normally on our slowest day of the week, RAM usage is around 20%-25%. We see RAM usage increase as more users hit the site, thus, RAM usage historically, has been tied to public bandwidth. Recently, RAM usage has been hitting 32%-35% on our slowest day of the week (as indicated by bandwidth usage). I am guessing that something is keeping apache threads opened and/or a cron-driven process which invokes httpd isn't finishing for whatever reason. This is only my guess after some research and looking at whm reporting and top. With my limited server knowledge, these are only my guesses.
1. What could be causing this increase RAM usage?
2. How do we find out what is causing it?
3. We did recently installed the OpenX ad server but there are no ads being served, we just implemented the CRON job for testing purposes. Maybe this could be the cause but how do we tell?

which type of CPU would be better for a web server that will run Windows, PHP, ColdFusion, mail, DNS, and IIS. Would a dual core CPU with a higher clock speed do better than a quad core CPU with lower clock speed? For instance, would a dual core 3 Ghz processor do better than a quad core at 2.4Ghz?

Do any of you know the best way to build a high reliability e-mail system?
I currently have Interworx as the default Control panel but are happy to change to Cpanel or otherwise. The iworx HA is not that good as if the cluster manager fails you loose everything.
I guess my only option is to do what most companies do and hope for the best - but have a good disaster recovery plan.

We are trying to use the new Wordpress toolkit, but when we try to install an instance it says this:
Contact your service provider for assistance. Upgrade the system PHP CLI to version 5.3.0 or later, or set the correct path to the PHP CLI in the clipath option of the php_handler utility for a custom PHP handler.
Screenshot:
Now that would not be a problem if the requirements were not met, but there are installed PHP versions that are higher than 5.3 and the website is configured to us these versions...
# /usr/local/psa/bin/php_handler --list
id: display name: full version: version: type: cgi-bin: php-cli: php.ini: custom:
2 5.5.14 5.5.14 5.5 fastcgi /usr/local/php5514-cgi/bin/php-cgi /usr/local/php5514-cgi/bin/php /usr/local/php5514-cgi/etc/php.ini true
3 5.3.29 5.3.29 5.3 fastcgi /usr/local/php5329-cgi/bin/php-cgi /usr/local/php5329-cgi/bin/php /usr/local/php5329-cgi/etc/php.ini true
cgi 5.2.17 5.2.17 5 cgi /usr/bin/php-cgi /etc/php.ini false
fastcgi 5.2.17 5.2.17 5 fastcgi /usr/bin/php-cgi /etc/php.ini false
module 5.2.17 5.2.17 5 module /usr/bin/php-cgi /etc/php.ini false
The website is using this version, and the PHP CLI is defined in the php_handler tool
I must be missing something obvious.

is it really worth the money nowadays to put in SCSI or SAS instead of SATAII (single disk, non-raid here), IF reliability is the only concern (i.e. NOT i/o performance) during the usual 3 year life time of a server?
Actually, I was pretty amazed by the sata reliability, in the past 3 years the only hdd failure was two sata on a mismatched mobo, which didn't support SATAII (a lot of read/write error, eventually died). Although we have 0% scsi and sas failure.

to colocate a 1U in the DC metro area for $100/month for a small non-profit I work with. The service necessary is pretty basic -- 1Mbps or so would do (preferably unmetered so we're not on the hook for overage charges), 1 or 2 IPs would be fine, and the only real service necessary (besides steady power and connectivity, of course) would be the occasional remote reboot and 24/7 facility access.
I've come close to settling on Crosslink Internet (web site at www dot crosslink net, silly system won't let me post the URL directly because I'm new), because they're the only place I've found that can meet that price point. Before I commit, though, I wanted to hear from you guys:
* Are they a reliable ISP? They sound sort of low-budget over the phone, and while that's not necessarily a valid indicator of reliability, it makes me nervous.
* Are there any other decent ISPs in the Northern VA vicinity that could meet this price point that you guys would suggest over Crosslink?

I currently have a Signature VPS with Servint and although I have found their customer service good and am getting concerned about my VPS's reliability. This is the only VPS I have experience with.
At the beginning of the year I was experiencing downtime at least once every couple of weeks and for at least 20 mins each time. Sometimes my VPS was down for over an hour. Most of the time the explanantion I received was a "Kernal Panic". Then for the last month and a half things have been good with no downtime, until today when my VPS went down again for about 50 mins.
So here I am asking what is normal downtime?
Is the downtime I am experiencing the norm and would I get the same reliability from any provider?
Would a dedicated server tend to be more reliable than a VPS?
I am considering moving to a dedicated server at LiquidWeb, not because I need the resources but I am wondering if reliability would improve. I am willing to pay for reliability! Any advice as to whether this would be a good move?

I currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.
Here's the overview of the VPSs:
LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL
Virpus VPS- 384MB RAM, 61 sites with moderate usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL
Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.

I would really like to know which hard drive brand you have had the best success with in regards to server hard drive reliability. Is it Seagate or Western Digital? Or is it one of the other brands? Please vote. This poll is specifically regarding SATA2 hard drive experiences in servers. Please do not factor in SCSI hard drives.

what's going inside my provider Powervps/Defender hosting, they are offering now 25% OFF of new customers + triply bandwidth.
Curent customers are not allowod to get this offer, until they order a new VPS and cancel the older.
I'm asking, because i feel, it's samething, why they don't go upgarading the account throughly with keeping IPs and data..? why do old customers need to cancel the old VPS then they go get a new VPS..?
are Old VPSs powerfully then the newest..? any informations...?

Is there any conventional wisdom on WHT about which shared hosting providers have highly reliable email service?
The provider I have now has very good web hosting service but their email services tend to bitbucket far too much mail for comfort. Reliable delivery and reception for the half a dozen emails I might send/receive a day (it's a personal use site) is I hope not too much to ask without needing to pay and arm and a leg for the privilege.

Last month I order 2 Xen VPSs from Xenvz.co.uk and use them for VPN proxy.
But a few days ago, xenvz stopped one vps and state "This is because it is spreading the Conficker virus.". I'm a little surprise because there's only 10+ users on this vps. Most of them use VPN for visting Youtube or P2P download or gaming. And Conficker virus can only run on Windows, but all my vps is running on Debian.
Maybe someone had download something that contain Conficker virus?
Anyway, I had to move a few users to another vps yesterday.
But xenvz stop my another vps today for the same reason!
I really do not know whether or not one of my user is spreading or other reason, but as I know, Conficker virus had affected thousands of hosts in the past. If someone download or being affect by conficker for any reason, provider then stop their host, I'm afraid thousands of sites would down.

Requires a dedicated server in Europe.
Requirements:
1) Processor: Intel Core 2 Duo 2,2 GHz;
2) RAM: 2024 MB DDRAM;
3) Hard Drive: 2x 250 GB SATA (can be smaller);
4) Traffic: At least 1000 GB or unrestricted;
5) Port: 100 Mbit / sec. (ideally 1000 Mbit / sec.);
6) IP-Addresses: 2.
Mandatory conditions:
1) A great date-center;
2) Operational and anglophone support;
3) Ability to establish a panel, for example: ISPmanager.
Recommended requirements:
1) Protection against DDoS-attacks;
2) The ability to administer the server, a company that provides services to lease (regular updates, round-the-clock monitoring, etc.).
The server is designed for the site, which will:
1) Forum;
2) Video and audio materials (up to 20 spots, for up to 10 minutes each), which can be viewed directly on the site using flash-player or download. Clips will not be frequently changed or supplemented;
3) Downloading developed software, up to 0.5 Mb;
4) Download documentation formats: DOC and PDF, up to 2 Mb;
All audio, video and documentation for its own production.
Additional information:
The number of visitors, initially to 10000 per month (probably much less or slightly more, not yet known) The audience will be visitors from the following countries: Ukraine, Russia, Poland, UK, Germany, France, USA and Canada.
Budget:
up to $ 200 a month. But if such amount is not sufficient for the entry requirements, are ready to revise the budget.
Need a really high-quality channel of communication and operational support, etc. Perhaps for these tasks, you recommend other requirements to a server and placing the territory? Check your real council.
Also look in the direction of affordable rental server and utilization of services: Akamai Technologies. If someone has experience working with Akamai, I ask, share their views. Should I use it for such a project?
A lot of information has been revised to servers in Germany, UK and USA. But the single answer, yet to be found.

I'm completely torn on going the absolute budget route vs spending more for something that'll allow easy upgradeability in the future. I basically need lots of space but file sending-- media like mp3s, video, etc.
it'll be raid 5 and I'll need at least 2-3TB initially but the ability to expand would be nice.
option 1:
nice chassis with plenty of hotswap bays with sas expanders
expensive sas raid card
option 2:
cheap chassis to serve "immediate" needs and go with more later.
not sure what I'd use as a card? maybe even onboard?
regarding reliability: I once saw a database of failure rates of different models. raptor was the most reliable of the "desktop" drives. anyone have the link? I'm wondering of the seagate ES drives are worth the extra money vs the non-ES drives. they're supposedely more reliable and the "server versions" of sata drives.

Most VPS offerings have "burstable" memory allocations. I get how you can do this with most things -- letting a VPS access more CPU cycles can be done pretty easily, and a 10 Mbps line burstable to 100 Mbps makes sense.
But how does the guest OS handle all of a sudden having more memory? Since a lot of VPS guests run without modification, how does this work? Does the typical Linux system support dynamic changes in RAM? I can only imagine that dealing with "un-bursting" is even more complex: suppose I have 128MB, burst to 512, but then the host node tries to reclaim some of it. Is the system smart enough to seamlessly swap out to disk when RAM "disappears?" I'd fully expect a kernel panic when the system's RAM shrinks in size, particularly when the RAM was in use.
I'm curious about exactly how all of this is managed. Given that 95% of VPS hosts give a burstable range of RAM, what exactly manages this? Is the virtualization platform handling this and somehow "tricking" the kernel, or is the guest system able to deal with changing RAM allocations? And, if the latter, is this a standard feature of the Linux kernel, or are guest OS mods still necessary to deal with burstable RAM?

With Windows 2003 server, there are comprehensive lists of what you need to do to secure the server before use. For Windows 2008, I wonder is there such a list? Or is it true as what I heard from Microsoft that it is already secured out of the box?
Anyone has any resources on the hardening or preparation of 2008 for server hosting uses?

I'm making a reasonably uninformed comparison here. Since Windows Vista is noted to be more resource intensive and slower than Win XP, are we right in assuming that Windows 2008 is slower than Windows 2003?
For instance, with two boxes with an identical hardware setup but the two different server OSes, will the same application like, say MySQL run slower on the Win 2008 machine?

There seem to be strong forum rules in place about the kinds of posts that hosters can make.
But from my perspective it is somehow leaving a large gap in useful information I would like to know that I can't quite put my finger on right now.
So I would like to get responses from Windows hosters in this thread without violating any forum spam guidelines and I sure hope I'm not wasting my time here with this concept but here goes...
So, the topic:
Ultimately, the thing Windows Web Hosters are providing is the delivery of information that has been constructed by developers using program code they have assembled using a large array of mostly .NET technology.
The reason the Hoster is providing Windows hosting is that a sufficiently large enough population of Web Developers have been attracted to some aspect of the Windows technology stack.
And there is certainly lots of innovative and interesting technology that attracts developers to focus on .NET in just the same way that there is also interesting technology in the Linux world.
So here's the problem. It appears as if the Windows hosting companies with the odd exception have almost no interest in Windows and .NET technology.
But if they actually did have such an interest, it is not clear how they would communicate it for discussion here at WHT because of the spam rules and of course trying to communicate anything at all about hosting on the general internet is just swamped by spam. The noise level is just insane!
So I am hoping that such a discussion can take place in this thread by asking some very specific questions:
1. What interesting Microsoft technology have you researched, tested or played with lately?
2. What programs or scripts have you personally developed lately to investigate .NET 3.5 features?
3. What do you think of XBAP delivery from the net and why do you think it hasn't caught on in a larger way since it sure delivers a richer client experience than Flash or even Silverlight.
4. What do you think of Azure and will Microsoft let hosters be part of the cloud anytime soon? Can you think of useful or interesting Azure mashups from a hosting perspective?
5. Have you tried any totally silly and insane things with the .NET runtime inside of SQL Server 2005/2008 that would give your DB guys a heart attack?
6. Have you tried out the Google systems where you give your employees 20% of company time to play around with personal projects like this?

Latest Update 12.0.18 Update 12 appears to have removed PHP 5.4 and PHP 5.5 from my dropdown under hosting settings.
The only PHP that is left is PHP 5.3
Yet, the updates and upgrades page still lists PHP 5.4 and PHP 5.5 as installed.
Also PHP is still working on the virtual websites that were previously enabled with either 5.4 or 5.5, but not able to change using the Plesk Panel.
Given that Parallels has broken the Panel in that latest automatic update I'd hope it can be resolved ASAP.
I can't even find any references in the KB about Plesk 12 on Windows regarding PHP versions
I can even give feedback about the broken patch as every feedback channel requires paid support.

Prior to using plesk, I had a few sites that had SSL certificates installed, the old fashioned way (manually through IIS). I have now setup those domains in plesk, and I need to somehow make PLESK aware of these SSL certificates.Right now, I setup the domain in plesk, give it a dedicated IP, and allow SSL connections. It chooses the default certificate and my already installed in IIS SSL certificate isnt listed.
Is there any way I can get it listed? I went to the add an SSL area, and it seems that this area is only good for generating new SSL certificates, but mine is good for another 1+ years.The bummer is that for some reason, anytime I make any type of change to the site in plesk, that it seems to overwrite the SSL bindings and changes my manual changes to the correct certificate (through iis) back to the default certificate.
