So you only back up for crashes? No hardware failures or user errors ever occur? Please tell me you are not responsible for data in a company setup. If so, what would be the best approach? RTFM - the documentation of your virtual host technology. VPS backup is trivial from the host level and supported by every visualization technology ever produced for ...

Assign a second IP address to the same VPS. Problem solved! Oh but wait, you can't do that on Digital Ocean. Lesson learned: Know your providers. Know your needs. Don't use providers that don't meet your needs, or work around their limitations.

You appear to have configured multiple A records. The domain points at both 184.168.221.55 (GoDaddy) and 94.23.211.117 (OVH). Delete the GoDaddy record and you should be fine (note: DNS gets cached, so it may take a few minutes to a few hours for it to stop happening). Right now, you've accidentally implemented http://en.wikipedia.org/wiki/Round-robin_DNS.

First: Thank you all for your help regarding this issue. Second: Due to circumstances, we were no longer able to wait and decided to reload a different back-up, which seemed to work. We were unable to determine what exactly caused the error due to the new back-up that worked didn't have any differences with the one that failed and we thus consider it to be ...

Yes you can, you just need to install vnc4server, tightvnc or realvnc. I use windows 7 on my desktop with tightvnc viewer as well as my windows 8 laptop.

To see true load inside the containers, you'll need an agent running inside the containers that can inspect process details that Dom0 tools don't have easy access to. Pick a monitoring tool of your choosing and use that to monitor both your host and your guests.

Without more information on your platform, it's a little difficult to speculate. However if you can SSH in from another machine, check the iptables rules with iptables -L as root. You may see rules under a "fail2ban" chain or something like that, which relate to your machine's IP address. They will end in DROP or REJECT, and they'll be the rules you'll need ...

Could try doing an nmap of the server to see what ports are open on the network. You should see port 22 open.

I see apt-get is your package manager. If you are using Debian Sid or Testing, these break OpenVZ compatibility with their core packages (kernel, systemD stuff) almost constantly. After the third go around I just switched to Fedora.

check if the server is able to ping its default gateway check if the ping works to server from outside if ping works , then do a tcpdump on the interface to check if the NIC on the server is receiving any traffic try ssh from with in the server -- ssh localhost #if this does not work - sshd itself might be broken

Based on your problem description it would appear that Netbeans includes an ssh client which only supports these older key exchange algorithms that modern OpenSSH server versions do not have enabled by default. The normal ssh client installed on your system, however, does support some key exchange algorithm that is enabled by default on the OpenSSH server. ...

Generally your home machine will run circles over this low end VPS - but that low end VPS is exactly that: Low end. I am sure you will find VPS offers that are a lot moew powerfull from your provider. Virtualization has many advantages, but it will not magically make a low end VPS faster than a typical higher end desktop. OTOH some tasks do not need that ...

The advantage of a VPS (presuming with a lightweight and GUI-less operating system and the purpose of solely being used to run your application) is that it has allocated power and performance for your app and it's system and nothing besides that. Your household desktop needs to boot into a performance heavy graphical operating system as well as it runs tons ...

Is kernel module nf_conntrack exist at /lib/modules//kernel/net/netfilter/ and loaded? If exist try: modprobe nf_conntrack

The issue was a mixed issue. It was performance on the VPS both also on index on mongodb. I added correct index and it fix some of the issue but had still some slow queries due to the slow CPU. So moved to a dedicated server and everything got fixed, answering under 80 ms now, instead for 22 sec. The VPS was overloaded with clients so my CPU was 60-70% ...

Do I need to change the hostname of the VPS? A system can only have 1 hostname but many DNS names can be pointed towards it, but there is no technical requirement that favours one of those additional DNS records over the current hostname. If you do change the hostname, just ensure that the reverse DNS records is updated accordingly. Do I ...

If you are running PHP on Apache, I don't think so. If you are running Tomcat like i am, then yes, Java threads will run on each CPU. So it very much depends on what you are doing. Of course, if you have a web server and database, then each should be able to run on a different CPU, and that should improve performance as well. I am running 512Mb server on ...

Most of OpenBSD’s internal daemons are already privilege separated and chrooted.
