VPN - What Kind Of Processing Power And RAM
Sep 24, 2007
I am planning to set up a VPN server for a group of about 4 people who will use it as an "internet proxy" for *all* their internet connectivity. (They live in a country where internet activity is severely restricted (and monitored), and I think a VPN would be a good solution for them.)
However, I have no idea what kind of processing power or system resources are needed for this kind of situation. Is a simple VPS ok? How much memory would be good? How about server speed?
The server will be linux (probably CentOS) and will use OpenVPN.
I'm thinking that there probably doesn't need to be a whole lot of raw CPU power or RAM, but maybe I'm wrong?

I have a client which run an active CMS and the server is utilizing the swap space at the moment. It is running on 6GB memory and a Xeon processor now. Is there anything that I could do before going for hardware upgrade? The apache and mysql keep exhausting the memory during peak hours.

do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.

What kind of spec would I need for serving direct/hotlinking 100mb+ files? I've looked all over the place but couldn't find anything.
And let say a sudden spike of 400+ people and they are downloading a file [url]simultaneously that is 100mb+ in size.
How much ram would I require?

I'm not quite sure how much of Ram I need for my vps, But I'm going to get
1GB Vps from wiredtree.com
Anyone can tell me what kind of website I would be able to run on such an VPS? If it's just wordpress driven website...
Maybe anyone can share how much traffic your site have and how much ram it's using?
At the moment I have website with about 40k uniques/day and ~100k pageloads per day hosted on shared hosting but they have gave me 3days to find another hosting because they say I use to much of their traffic...

current LSN customers (if possible) check what kind of hardware is their server?
I am looking @ Q9550 offer they have.
If somebody could check MB, RAM, HDD models.
Also, is there anyone on their 10TB plan?
Do they really allow customers to do this BW?

I'm just posting a little topic here to see what kind of demand numbers and opinions I might get for the Hybrid VPS industry. Hybrid as in semi-dedicated, being packages like 2GB ram, 25% guaranteed processor, etc. "Semi Dedicated" if you will. I've been considering opening up a sub-company of GeekLayer for a few weeks now that sold fully managed xen virtual private server "hybrids", although be it with a slight twist.

i have about 80 domains with godaddy and about 30-40 with 1and1. i have two hosting packages with 1and1 a "home" package and a "business" package. i have a main site up on the business package right now. the home package has tons of files from an old forum that really could just be wiped out.
My question is that i have a few sites being developed right now. 3-4 to be exact, can i host them all on the same package? i want each to not be a sub of anything. What do i do? Calling tech support yielded worthless answers. Do i need a different type of account?

What kind of raid array can I use while it's being rebuilt?
For instance if a HDD fails, on my servers I need to take the server down in order to rebuild the array. I'd like to be able to rebuild the array without the users to notice it.

I had a pretty hectic week dealing with these 3 customers with ddos problems and got to try a few different ddos datacenters for each of them.
First I got these two anime sites, I put them on mine and a friends staminus box as soon as their dns resolved 1000s of ips came through sending syn on port 80, it would just knock port 80 out filling up contrack table, etc. Id ban a few hundred ips and some ranges 100s more would come. In the bandwidth it only shows about 200kbs incoming as well.
We had put in an emergency ticket with staminus and was told bascially we are idiots and that only 4 packets per second were coming into the server, I was looking at the tcpdump and the kernel was dropping 10-20 thousand packets a second just from the ips id banned.
So after a day or two of this of saying we didnt have an attack I moved them to a gigeservers vps I got from funtoosh at sh3lls.net As soon as I moved the sites over there it stopped dead so giges filters automatically picked it up. So either staminus doesnt protect against that type or what. It seemed like a a regular syn flood.
So for customer 3, this person has had numerous problems dealing with ddos. He says that the attacker has this tool that exploits the verlisign dc++ hub, that it takes over and has every user send ddos to the server of their choice.
he had been on sharktech a few months per my reccomendation, he said they could not stop the attacks. he came to me said this was his last resort, so I said well surely staminus would stop it. As soon as his dns resolved on staminus server it got destroyed, nothing got filtered, couldnt even login the box. I didnt have access to staminus portal so I couldnt file a ticket, I had went in their irc again and could not get them to nullroute the ip, understandable since I didnt have access to the ticket system. So I immediatly deleted his dns and the attacks came for up to 12 hours hitting the ip he used to be on.
Id ban thosands , entire /8 ranges and it would just reload and start hitting again.
These syn floods sent very little data at slow intervals so i see why it was so hard to filter.
SO then I move him to gigeservers vps, his site is now up 12 hours, in netstat you would see teh occasional ip coming in and sending syn then closing connection so I thought it had it filtered. We was celebrating, as soon as we did I relaized I put my foot in my mouth as the attacks started full scale there. Nothing i really could do software wise as the vps kept running out of memory So I just had funtoosh remove the ip.
My client the victim was hanging out in their dc++ hub at zerohour.mafiahub.net and pasting ne the logs translating from romanian on how they commanded the attacks. But supposedly they can connect to any dc++ hub and use this tool to take it over and have every user on the hub send ddos. The tool and exploit they are using is private thank god so it seems only a few romanian hacking groups have this.
This kind of attack could not be filtered at sharktech, staminus, or gigeservers I had tried it on softlayer first, had them add it to ddos guard, it knocked Both my servers offline that was on same subnet. It sends very small packets and slow intervals, there is absolutely nothing you can do software wise.
Just giving everyone a heads up on what kind of methods are being used. If someone does think their hosting can block these attacks via hardware or software id be more then happy to give you the customers name, and they do not care to pay as long as the attacks can be filtered.

I using RHES 4 + cPanel.
I have MySQL 5.x, and PHP 4.4.6.
I noticed that all sites on the server, can not parse php files, tried restarting httpd, recompiling using apache update or easyapache script, and the problem stills.
index.php is at DirectoryIndex, also Addtype shows php extension active at httpd.conf.
but, when I type "php -v" from the shell, i got this message:
Code:
php: /usr/lib/libmysqlclient.so.14: version `libmysqlclient_14' not found (required by php)
I found someone with the same problem, tested the solution posted there but it doesnt seems to solve this issue.

I have a dedicated that is oversized for the task (Q6600, 8gig RAM, Sata Raid-10 array), which is running a medium/small vBulletin site.
I have thought about providing free image hosting for the members, so I could have 100-300 people hosting sig images and other graphics on the server, which they in turn would link into forums and other places which could create quite a few requests for those graphics.
Is there anyway to quantify what type of load this static, image hosting would create?
The server currently is typically around .05 to .1 server load with nearly flatlined CPU's.

I am wondering, when you are offering MSSQL server in a dedicated server, would you quote your customer a Per Subscriber License? or Per CPU license? It has big big differences. What is the common practice? I have an headache studying the complicated license usage details.

I used a script to block some unwanted countries from accessing my site. In total I had about 3000 lines with ipranges. Now I just went ahead and put this on one of the servers, one that I really don't need the traffic on. But I am wondering what kind of affect this may have on the speeds. Will it really affect it more then a few ms? And anything else I should maybe worry about? Except maybe the loading time at reboots.

im running centos and have a fairly high-end server. yet my services seem to be running a bit sluggish. is there a way to differntiate if its the server or the connection?
using free -m -t im only using half of my ram
(i dont know the command to check how much of my processors im using). im going to assume that that is also 50% or below. if any one has this command please let me know. if its not either of those im guessing its either bad routing be bounced everywhere, or some more localize like datacenter issue, bad router or something.
on a side note whast the command to restart sftp?

I have a hosting provider who cannot provide enough ram to run my one time PHP script (gallery2) (and has a automatic background program kill my task)
So I would like to use processing and ram outside of that server.. via one of my other web servers.. (Dual 1 Ghz, 1 gb of ram) the thing is that the servers got plenty of power but not as much space..
So the ideal solution.. would be to utilize it's power while having it access the hard drive/data remotely and processing it remotely... using the internet/ssh to do this..
Does anyone first off know that this is possible?
2ndly what would be some of the commands?

I want to host a torrent search engine (not a torrent site with actual torrents hosted, only a search engine).
It has to be really fast. I have a few questions?
What hosting is required for this site to be lightning fast? Most of it is due to the coding of the site but how much of it is reliant of the server? Any suggestions?
Also, is it better to start small and upgrade as more visitors come? Or is it just better to get a big server?

I'm wondering what kind of prices you would be looking at for some private data center space, maybe in the InfoMart or one of Internaps data centers - somewhere in Texas though, preferably Dallas. Is there any kind of rough monthly price I should expect? Maybe a standard per sq ft charge?
Also, if you rent a private "suite" does that include office space, or would that still be needed separately? How much would it be to get a small (100 to 500 sq ft) office in the infomart?
Cabinet Suite (Internap only it seems), and private suites would be considered. Possibly a cage or private rack, but not preferred.

I have a windows 2003 VPS and I'm not satisfied with the HD I/O speed, and before I mention what speeds I am getting I just want to see what people say should be plausible. I want to know if I am thinking I should get more out of the VPS then I really should.
Anyway, I used this program from ATTO to benchmark:
short-media.com/download.php?d=108
Called ATTO Disk Benchmark
If anyone is willing, run it on your VPS and post a screenshot. It's a standalone .exe, no install needed.

I work for an academic department which utilizes one web server, and has few issues with processing time and/or speed during the year. However, there is one point during the year when there is a need for a significant number of processing transactions, which opens all at once at a certain time on a certain day for everyone, that the web server cannot handle and is currently not occurring.
I need to find a service that can handle this. Basically, we would just need to insert info into a database (or whatever input form works) and then later export that data into a text file to be inserted by us at a later time. This is not credit card processing, which is why I'm posting. However, this would need to be secure. We only need the use of the servers and a database.
