Concurrent RPC server
===

I need to create a concurrent RPC server which is capable of handling multiple requests from client simultaneously.  

Using rpcgen compiler in linux (which is based on sun rpc), it does not support -A option which creates stubs for concurrent servers. ( -A option is available in solaris)  

Appreciate if someone can provide some idea on this:  
1. What is the way to create concurrent RPC server in linux. Some googling suggests making changes in stub, which isn't a good idea.  
2. Any other RPC packages available - alternative to sun rpc.
