VPS5 is dead

Hi

I am using VPS 5 on node DC-2, server ID is 5146, which recently went unresponsive.
I am unable to reboot, power down or power up the VPS via the panel, it shows the VM as running, virtual console does not work either.

've made a good bit of headway on my open source site, and as my posts rise I'll soon be able to host my site on 1 vps with a good top level domain perhaps even some surplus of resources.

I'm learning oodles and accustoming myself with the rigors of maintaining an online server. While I'm posting here daily, I'm also checking my access logs, restarting services as needed, and altering configurations to maximize performance. It's my hope that within the next few weeks or maybe a month I'll be live and stable enough to give back to the community that gives so much to me.

Is there any particular service members would like to see? I don't have anything in the budget for big commercial software like whcms or cpanel. Any service I offer needs to be small and easy to maintain, at least in the beginning.

Some ideas I've had so far:

1 would be to offer free shell accounts with 1 open port per user. No web hosting but would come with local database access, cron, local file storage, and whatever scripting/developing tools I can figure out how to set up. There's not very many of these hosts left and they always come with tons of restrictions.

2 would be to offer free database hosting. There are tons of free web hosts out there, more than you can shake a stick at. While using these free hosts for the last few years, one thing I've become very aggravated about is poor database hosting: connection timeouts and low execution times being the major flaws. I'd be happy if I could give even 1 person an unrestricted database they could use for a good cause.

3 hosting a chat server for public use. Which reminds me I still need to figure out that anope issue with the ports *makes note*

4 I could give people hosting for an open source project of their choice, provided I can get it working. A wordpress blog, forums, or wikipedia or something similar.

5 Mirror repositories of some of my favorite open source projects. The sky is pretty much the limit here.

When choosing these services, my primary goals are

A: I want a service that's high quality. If I have to add each member manually and do all the configs myself I can live with that. What I don't want is an automated service that gets spammed with users so badly that I'm unable to offer a quality service. No matter what service(s) I offer, I intend to add users slowly to see how the server handles additional load. I do not intend to make any public offerings at this time, but will restrict access to responsible members of the communities that support me.

B: I want a service that is somewhat unique, or at least one that there aren't thousands of others like it. This kind of detracts from #3 and number #5

C: I want a service that will challenge me to grow and learn, but that isn't beyond my skillset to maintain. It won't help anyone out if I'm offering free databases and I get hacked and bring down the network. I never went to school for any of this stuff and all I know is what I've managed to teach myself over the years. Still, I think I can accomplish some good service with my 15 years experience using open source tools, and hopefully not screw it up too badly if the community is there to catch me when I make a mistake.

Now, if you've managed to make it through all of that, I'm welcome to know what services everyone else would like to see. Try to make it fall within the outlines of my goals, not too common, not too difficult, but something useful and unique.

As always questions, comments, suggestions are always appreciated.

I fully admit that I've got plenty to learn and the experience with a vps is quite new to me.

One thing I am very uneducated in is network security. I have a basic understanding of access rules and permissions, but beyond that, what can one do to protect one's data?

I've had the vps for a few days now, and I've been mainly focusing on getting the config files just right. I found that after I got wordpress running my apache daemon's became very bloated, so I dropped php mem limit from 128 to 32mb, which helped a LOT. Also I realized that I don't need to leave the ftp server on, I can use it when installing files then stop it, which also saves me some resources. I think in time with a bit of tinkering I can get a setup just right to serve fast pages and services even on a small free vps.

However, I'm wondering what vulnerabilities I might have that I'm unaware of, and other people are too!

I looked at my apache logs today and saw several people poking around.

Several HTTP HEAD requests from Russia 185.xx.xx.xx (5 diff ips)
A couple GET requests from Amazonaws 54.xx.xx.xx (just 1 ip 4 queries including a get of my wordpress readme.html)
Scary GET request from Poland (GET http://testp4.pospr.waw.pl/testproxy.php HTTP/1.1")

The last one definitely looks to me like some sort of vulnerability probe.

I banned the poland IP, as well as the amazon IP (I don't like people testing nor viewing my readme without asking first) but for now I've left the Russian IPs alone. Deny rules at the top of IPtables

The requests *seem* innocent enough and were just producing 403 and 500 errors. But I don't know... maybe they were doing a network scan for desktop vulnerabilities and that's why the errors were produced? Maybe next time they'll search for server vulnerabilities?
Maybe they're all completely normal search engine requests?

I'm wondering if I took appropriate action in banning the ones I did, if I should ban the rest of them, or if there is further action that I should have taken, or any general thoughts/opinions/suggestions/comments someone with more experience might have.

I know everyone has opinion, and people will often disagree but also that people use different devices to connect, and oftentimes what looks great on one screen looks terrible on another.

While I wouldn't classify the post4vps index as terrible, I feel like it needs a little bit of work. I don't really like the way the description is tightly packed in on the left, and the thread count/post count take up such a large area. Better for me if the description took up a large area and the thread/post count were much smaller.

In closing I want to thank you for the services you provide and I hope this suggestion is useful. Enclosed is a screenshot. I've scaled it to 800x600, hopefully this is an appropriate size to not overburden the forums.

Introduction
VPS 5 is hosted by https://cobalthost.net/ and was given to me during the last VPS giveaway. It's located in Canada and uses VMWare as visualization technology, which offers great performance and flexibility. Specs seem fine, especially 50GB diskspace and unlimited traffic.
Specs in detail:

Disk Space 50 GB
RAM: 2 GB RAM
IP Addresses: 1x IPv4
Virtualization: VMWare
Monthly Traffic: Unlimited
Location: Canada
Control Panel: Cobalt Panel
Connection: 100 MBit/s

Detailed Specs
The VPS has 2 Xeon Cores

Code:
sysctl hw.model

hw.model: Intel(R) Xeon(R) CPU           E5335  @ 2.00GHz

Xeon looks awesome on first glance, but if you look it up, it is a 9 year old CPU and that shows, as we will see in later benchmarks.
http://ark.intel.com/products/28443/Inte...33-MHz-FSB

Installation
cobalthost is using their own Panel, which fulfills the basic needs, shows cpu/ram/hdd usage and offers the usual suspects like reboot/reinstall etc.
CPU Usage is always wrong in the panel, mobil version does not work. Installation works, which is most important.
One can choose to install on DC-2 or DC-3, since nowhere i can see the utilization of either node or see what hardware is in it it's is a gamble.
I first chose DC-3, which was a mistake. It is so slow that there can be only 2 reasons for it. a) it has like hundreds of VMs running, or b) the hw is dying (as in faulty), possible the hdds.
Booting a VM takes up to 5 minutes, installing ~30 minutes.
So i reinstalled on DC-2, which works better, boot and install times are normal. Installation went without issues. Their install script leaves a /bin/npasswd script back and a non working rc.local entry in case of debian. On FreeBSD i could not find any artifacts but 2 installed packages.
There is a slight installation bug with FreeBSD, which i already reported. (swap missing), also it installs on UFS2 instead of ZFS, which is a bummer but should do for most tasks.
One cool with with cobalthost is that you can have as many VPSs as you have resources for, so with 2 cores you can do 2 VPSs. Very cool.

Benchmark
Since i am running FreeBSD the usually FreeVPS benchmark script won't work, so i had to improvise and used unixbench.

Now that looks kind of horrible. As a small comparison a FreeBSD VM on an older core i3 under load in production had a Final Score of "231". FreeBSD VM in an older Xeon also in production with load on it did "362".

Now that is also right up the raspberry pis disks speed as well. In all fairness, doing the test during different hour yield better results at around 12-30MB/s

That should be enough to get a rough idea and be able to compare with his/her own VPS/Desktop

Network:
Now the specs say 100mbit, but in reality it is connected with gbit, which is nice. Speeds inside Canada are good, ok to the USA and not so good to Europe but that was to be expected.

upload speeds are worse, why that may be, i think everyone can guess. Generally the speeds are good enough for any personal use, for me at least its enough.
My VPN does 15mbit (compressed) to my home link, which is enough for my VPN related activities. Also enough for mumble/teamspeak or a small private website.

VPS Usage
I mainly use it for playing around with Operatingsystems and run a mumble and an OpenVPN server, both private for myself. Maybe i'll use to backup some stuff, since the 50GB disk space is nice.

Reliability
Can not say much about that yet, for now it has been stable, if it ever goes down i will update this thread.

Conclussion
Well that is a mixed bag, it is very old, dying hardware and probably over sold into oblivion. So if you are looking for a VPS where you actually have to run something that needs power or disk speeds from this century you are out of luck. A quad core CPU for half their customers(DC-3 has 6 cores i think) is simply not enough, also the apparent lack of a storage for the VMs other than the included HDDs on the old server shows, very much so. If you are looking for a VPS to do some private stuff, test your code, learn linux, run some small daemons or anything similar like that it does its job, after all it's free and for free it's good, can't really complain. For anyone looking to invest their own money i would suggest to look for another hoster.
