I have a farm solution wsp which I want to add and deploy on a client's SharePoint farm.
Now I don't have remote access to this SharePoint machine but do have full admin rights to its central admin and related site collection, and can open the central admin and all sites through my machine.
Now as per my knowledge a farm solution is added to the SharePoint farm and not to the site collection, but I could not find any screen in central admin from which I can add my solution.
This is the case with both SharePoint 2010 and SharePoint 2013 servers.
What are the possibilities?
Basically, it sounds like you need to add and deploy a farm solution only using central admin? I don't think that is possible. If you look step one from MSDN
