Hello, I am new to tryton and gnuhealth system. I want to setup gnuhealth with tryton on three PC which has ubuntu 22.04 version and use same wifi connection. I install gnuhealth system on three PC with tryton and postgresql. I consider one as a main server and another two as a local server. Now i want to insert patient data or other data on a local server and want to the data is available on main server.I want it as a distributed system.Is it possible?if possible than please help me by giving your suggestion.

Hello Tarannom, you could probably receive more specific advice on GNU Health mailing lists: [GNU Health - Mailing Lists [Savannah]](https://savannah.gnu.org/mail/?group=health) . To federate data between several HMIS instances you may want to have a look at the federation server: [GNU Health/Federation Technical Guide - Wikibooks, open books for an open world](https://en.wikibooks.org/wiki/GNU_Health/Federation_Technical_Guide) ---

To me for only three clients federation sounds a bit overdone. I’s go with three clients and a single server. Anyhow, I never user GNU Health, so maybe it has some specialties which recommend federation even in small setup? ---

I consider one as a main server and another two as a local server. I think you misunderstand how Tryton works. Tryton uses the [Client-Server](https://en.wikipedia.org/wiki/Client%E2%80%93server_model) model. So you setup a server and install Tryon-server on it. On the PC’s you install only the Tryton-client. In short: As you said you have one as ‘main-server’. The other PC’s can connect directly to the ‘main-server’. Use in the login dialog as ‘hostname’ the ip-address or the name from your ‘main-server’. ---

Is it a kind of experiment ? any real requirement behind such a synchronization need ? ---

Thanks for suggestion. But i don’t want to directly connect to the main server from another device. I want to insert/delete data in one database server and that change of information will be updated to main database server. ---

Yes. At this moment I want to develop such a system so that it could be use for large companies in future. ---
