ERROR service 'sapgw00' unknown

You need to maintain your services file.

sapgw00     3300/tcp

sapgw00s    4800/tcp

Hi Juan,

Thanks for support and let me know how to maintain the services file as am unaware of it?.Additionally let me know some link or note for doing this method.?

The bottomline is that i have to establish the RFC connectivity to Non-sap application(Interfaces link team).i have given the Jco specicfic for OS/platform.And now the Non-sap application are not able to ping to listeners.And,i have configured the programID/RFC with gateway services.

Please provide me your solutions
