Primary DNS Servers vpsFree.cz operates shared DNS servers that you can use as authoritative servers for your domains. The setup process is as follows: * In the DNS -> Primary Zones menu, create a zone for your domain. The zone name is simply the domain name, usually a second-level domain, but you can delegate higher-level domains as well.

What Do I Get as a Member? CPU: 8 cores In the default state, we do not limit processor time for any VPS – if you need to compile something or you are at peak traffic, you have the full processing power at your disposal. All VPS have a specific priority setting so that they don’t interfere with each other. The processing time of the physical machine processors is evenly distributed among the VPS that currently need it.

Control groups (cgroups) - systemd 258

Control groups (cgroups) Control groups (cgroups) in Linux are used to account and limit resources of groups of processes. For example, cgroups are used to account CPU usage and let us configure quotas and memory limits. cgroups are one of the foundation blocks of vpsAdminOS: every VPS has its own cgroup and can of course create its own nested cgroups. This is usually handled by the init system and so you don't work with cgroups directly.

aither (aither@undisclosed.example.com) — 2025-08-16T12:29:55+00:00

Incident/abuse reports When IP addresses from our network are the source of spam or are attacking other systems, we often receive abuse notices. We're forwarding these notices to individual members who should then secure their VPS. The notices may also be precautionary when services which are known to be exploitable are available from the public Internet.
