Impossible to run MSSQL on Linux, which is what the server files require, you can however install freetds (apt-get install free-tds) if you're using ubuntu, which most people here probably use. FreeTDS are a set of libraries to be able to allow linux to natively "talk" to the Microsoft SQL Server . (I'm not sure if the package name is free-tds, use apt-cache search TDS - should come up). Also, i wouldn't recommend using the MainSrv DBSrv Auth etc on Linux, running it via Wine will be very unstable. The best way to do it is if you only have a linux server, Download VMWare for linux and install a Windows VM - problem solved.
