Transparency is our Mission

Netmonic Webseite Version 4.0

April 4th, 2009

Netmonic 4.0

Dieses Wochenende wurde die neue Netmonic Webseite live geschalten. Inhaltlich neu konzipiert und von unserem Grafiker, Daniel Marian, neu gestaltet, werden die Netmonic Produkte, Cloud Server und Remote Office, deutlicher positioniert, um die Vorteile für unsere Kunden klarer darzustellen.

Die öffentliche Webseite und das Management-Interface wurden explizit getrennt. Daher ist das Management-Interface jetzt auch direkt unter https://manage.netmonic.com erreichbar.

Die Mission “neue Webseite” konnte, von der Idee bis zur Implementierung, in 21 Tagen (und Nächten ;-) ) umgesetzt werden.

Großen DANK an alle Mitarbeiter!

Btw, we are also working on supporting this distribution: ;-)

Scale Server Statistics

January 2nd, 2009

our new feature “scale server statistics” is ready to use.

This feature enables you to monitor

  • cpu load,
  • uptime,
  • disk usage,
  • network traffic and even
  • host cpu load and
  • host uptime of the host, your scale server is running on.

You can select the period to display in the graph with the quicklinks or the two date selectors on top of each category.

selector

If you change selection an AJAX-request updates the appropriate category and displays new data.

Now to the graphs

In each graph the following values are stated:

  • Current is the last value collected.
  • Average,
  • Minimum and
  • Maximum are the respective values for the selected period.

Each graph is updated once per minute and the data is stored for 1 year.

Guest Statistics

cpu

CPU-Load is displayed as percentage proportion of how many seconds you used the cpu between measurement points. If you needed more than one CPU, the value can go over 100 percent. So an utilization of 100 percent says, you needed one CPU during the whole measurement period.

uptime

Shows how long your scale server is up in seconds.

IO Statistics

io

Shows how many blocks your scale server wrote/read to/from the respective disk.

Traffic Statistics

traffic

Shows you for each network interface how many bytes per second you sent/received.

Host Statistics

Here you can see the load average and uptime of your host.

host_load

host_uptime

New Virtual Machine Images

November 27th, 2008

We published a few new virtual machine images today:

  • Fedora Core 10
  • Ubuntu Intrepid
  • ArchLinux 2008.06
  • CentOS 5.2

Spam Filter related Outage

August 22nd, 2008

Last night one of our spam filters stopped processing incoming emails. This resulted in a delivery delay for all emails processed by this server.

There were no Emails lost during the outage.

We apologize for the inconvenience! 

OpenSSL Vulnerability CVE-2008-0166

May 16th, 2008

A weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system. This particularly affects the use of encryption keys in OpenSSH, OpenVPN and SSL certificates.

Basically this means that all SSL-Keys need to be regenerated.

We have already updated all our internal systems and virtual machine images, so all virtual machines built after today are already patched.

For older virtual machines, you have to regenerate the SSH-Keys.

For Debian and Ubuntu machines do the following:

Debian:
aptitude update
aptitude upgrade && aptitude dist-upgrade

Ubuntu 7.10 & 8.04:
aptitude update
aptitude safe-upgrade && aptitude full-upgrade

This will download fixed packages and regenerate the SSH Keys for you.

Because we generate all SSH-Keys on Debian bases systems, even for other distributions, you’ll have to update your SSH-Keys on Fedora, CentOS and ArchLinux as well. On these distributions it’s enough to delete the SSH Keys and then restart the SSH daemon:

rm /etc/ssh/ssh_host_[rd]sa_key
/etc/init.d/ssh restart

Bought a EMC DMX2000

May 15th, 2008

To get closer to our target architecture we need a fast, highly available and scalable SAN storage.

And therefore we bought a EMC DMX 2000 with 42terrabytes :-) 

After integrating this into our infrastructure, high available xen vms can be offered. Your XEN VM has no longer a dependency to a single server, it is now independent and can be moved in a running state.

Some facts:
42 terrabytes
288 * 146GB HD
32GB Cache
8 Fiber directors
 

See you guys to check this out (available in 8 weeks)

Reverse DNS for Virtual Machines

May 5th, 2008

As of today, you can now set the reverse DNS records for your virtual machines.


Wir haben heute ein neues Feature online geschalten und zwar kann man ab sofort die Reverse DNS Einträge für virtuelle Maschinen setzen.

New DNS Server

May 2nd, 2008

Tonight we added a third DNS server, ns3.netmonic.com to our infrastructure. The server is located in the USA and provides added redundancy for your domains.


Wir haben heute Nacht einen dritten DNS Server, ns3.netmonic.com, zu unserer Infrastruktur hinzugefügt. Der Server steht in der USA und bietet dadurch erhöhte Ausfallsicherheit für Ihre Domains.
