Hi,

I would like to make some simple network simulations

I've tried to make run few (under Linux or Windows)

Kathara
GNS3
EVE-NG (3.1 GB ! to download )
omnetpp
ns-3
Cisco Packet Tracer (Not FLOSS, if I'm not mistaken )

The only one that I managed to install, run and use (set some nodes) was sadly the Cisco Packet Tracer ...

They other have their install process way to much complex or with such layer of dependency or more simply they way the works is too complex (running side VM for each nodes etc..) make it challenging to installing.

Do youn know a FLOSS Network Simulator , this is easy to install ?

Thanks.

In the same boat as the other poster, its been like 10 years.

I used GNS3 and Cisco VIRL way back in the day.

Depending on your use case, you can pretty far with just docker and some Linux packages. I've done GRE, BGP, OSPF, ISIS, Open vSwitch. That's Linux networking though. If you're trying to prep for a specific vendor's cert, it might not meet your needs.

Does look like someone had success running virtual devices in docker that might be of interest: https://github.com/vrnetlab/vrnetlab
