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.

Packet tracer is definitely not OSS nor free as in speech. But it is probably your best bet for something to get started with. You can go on netacad and get it for free together with the self-paced introduction to packet tracer course. I'm not trying to shrill for Cisco, they're a soulless company that exploits their position to extort insane prices. But PT is kinda nice, IF! all you want is to build simple networks and you don't care about being vendor agnostic or only running FOSS.

PS: and cisco? 2900€ for a 24port l3 switch? GTFO, a mikrotik crs326 can do the same and is 200€ and it doesn't require a DNA-center to enable licensing, why? BECAUSE IT DOESN'T REQUIRE ADDITIONAL LICENSES!!1!one!
