Hi, what can i do to set multiplayer game on Master of Orion II on LINUX ?
Is possible find some players by network?
I must install TEN program or i need only a set for ip in some way?

It's a DOS game which uses IPX for networking, aiui.

DosBox should have IPX support built in, so it's just a matter of configuration. GOG provides some configs, I haven't tried them tho. https://www.gog.com/forum/master_of_orion_series/moo_ii_online_dosbox_guide/post2

Never played MoO2, but TEN.net is a very ancient paid multiplayer service that is quite defunct.

Reminded me of the days as a child I played ARC, Duke 3d & Shadow Warrior shareware on it. Good times.

ok, IPX i did try and work fine by server and client Master of Orion II ,but i did think the possible to connect to list of Master of Orion II online games by GOG server...

All DOS era games and most GameSpy era games are now LAN only, since their online modes have gone under a long long time ago. That being said there are ways to play LAN games "online", but they are outside of GOG's scope. Would be a cool Galaxy feature though, I agree.
