Yes , thereisn't the winsock unit. I don't know if in the FPC(Free Pascal Compiler)package there's !!
but the winsock delphi unit is only for WINDOWS, Lazarus is compatible also with Linux and others , i think it theresn't because the winsock unit isn't compatible with Linux .
If you see also in Kylix thereisn't the Winsock unit .
