| Free tier | 'Learn Linux from the safety of your chair using a remote private linux machine with root access.' Machines are booked from a queue: 'Your position in the queue, your speed in getting a machine, the amount of time you get using a machine, and the things you can do with the machine once you have one are all related to the information you give during registration. This can range from 10 minutes of machine time, up to 2 hours of guaranteed time with automatic time extensions if the site is quiet (which is called HOLD time in the interface).' unit minutes; metered on wall-clock |
|---|
| Price | none stated |
|---|
| Limits | - retention-clamped 10 minutes to 2 hours of guaranteed machine time, extended only when the site is quiet source
- retention-clamped the VM is shut down within a few minutes if no browser window has a control panel on it source
- volume-quota 7 server nodes of 192 GB RAM and 1 TB disk each, modelled for about 140 concurrent users source
- per-ip-shaping (binding) no outbound traffic; the guest is sandboxed to the virtual network source
|
|---|
| Binding | per-ip-shaping No outbound network means the machine cannot fetch a package, reach an API or carry a tunnel, which removes most uses before the two-hour clock even matters. |
|---|
| Identity | email no card, no phone, no document. |
|---|
| Egress | 'Firstly, the machines are sandboxed from the internet, so no outgoing traffic is supported.' and 'Free users are basically sandboxed to the virtual network.' There is no outbound path at all. free allowance: none |
|---|
| Per-object cap | 'You are allowed to have only one account per person on this site.' |
|---|
| Retention | 'This previous image approach is not precise and reliable (sometimes it will not give you your most up-to-date image when you request it). It tried hard to keep your work between reboots, but this is not guarenteed.' The disk files are deleted by the daemon 'as and when required'. |
|---|
| Interface | ssh SSH to the guest through a browser JavaScript terminal or a real SSH client at ssh [address removed], plus VNC for the images that run a desktop. Root on the guest; the images include AlmaLinux 10, Kali 2024-4, Caine Forensics and Windows 7. |
|---|
| Tooling | a browser, or any SSH client; VNC for the desktop images |
|---|
| Composes with | A root VM for a two-hour lab, with no account cost and no card, but no outbound network: useful for learning and for offline compute, useless for a tunnel or a monitor. |
|---|
| Reliability | The site's own front page carries a live 'Status: Stable' line and also the notice 'Patching and rebooting underway', so the service is maintained but not always up; the operator states it is a privilege rather than a right and that response time may be long. |
|---|
| Notes | The disqualifier is explicit and repeated on the vendor's own page: 'no outgoing traffic is supported'. That makes it a lab for learning Linux, which is what it says it is, and not a machine for a user's stack. A second constraint is the control-panel reap: the VM dies within minutes if no browser window is showing a control panel, so it cannot run unattended even inside the two-hour window. The per-VM shape is unpublished. The front page showed a transient 'Having a disaster' error block on the same read, so the service is live but rough. |
|---|
| Evidence note | documented The no-egress rule, the queue, the 10-minute to 2-hour window, the control-panel reap, the node count and the email requirement are all quoted from linuxzoo.net's own technical and how-to pages read. The per-VM vCPU, RAM and disk allocation is not published on any page read; only the host nodes' totals are. |
