Project README

Nyancat CLI

Nyancat rendered in your terminal.



Nyancat is available in the following distributions:

And also on some BSD systems:


First build the C application:

make && cd src

You can run the C application standalone.


To use the telnet server, you need to add a configuration that runs:

nyancat -t

We recommend openbsd-inetd, but both xinetd and systemd work as well. You should be able to use any other compatible inetd flavor too.

Distribution Specific Information


Debian and Ubuntu provide the nyancat binary through the nyancat package. A nyancat-server package is provided to automatically setup and enable a nyancat telnet server upon installation. I am not the maintainer of these packages; please direct any questions or bugs to the relevant distribution's bug tracking system.
