All the following services are present by default on all servers.

NTP Server

Network Time Protocol (NTP) is configured by default on every server. The system time is synchronized with our NTP servers and set to the UTC timezone.

You can execute the ntpq -p command on your server to see the details list of peers known to the NTP server.

root@c1-X-Y-Z-T:~# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================       4 u   15   64    7    0.311    2.796   2.392
 golem.canonical      2 u   13   64    7   15.250    6.745   2.095

DNS Server

Every server are configured to use our DNS servers to resolve domain name.


Every Ubuntu server uses the following mirror for fast updates as is it close to your servers.

Additional upstart jobs

The following scripts and configurations ensure that your server works properly on our infrastructure.

  • /etc/init/ssh-keys.conf Fetches ssh-keys associated with your account in /root/.authorized_keys
  • /etc/init/sync-kernel-modules.conf Synchronizes kernel modules

Additional files

Often you will want to automate your server configuration based on data unavailable before start.

For instance, if you use server tags to configure your monitoring, you can retrieve this data using the following executables.

  • /usr/local/bin/oc-metadata: Executable which retrieves server metadata (TEXT).
  • /usr/local/bin/oc-metadata-json: Executable which retrieves server metadata (JSON).
  • /usr/local/sbin/oc-sync-kernel-module: Executable which synchronizes kernel modules.
