Hello Experts,
I have an Eclipse Mars Installation (I also tried Luna) on my MAC OSX machine and want to connect to a CAR System.
I can log in in the SAP Gui 7.40, but not in Eclipse.
I get the Error Message:
Anmeldung an System *** fehlgeschlagen (hostname 'My Computer Name' unknown)
I have added an entry to the /etc/hosts file with 127.0.0.1 My Computer Name, as mentioned here: Hi Experts. I can not add the Sap System into Eclipse
Edit: Here is the error Log
com.sap.adt.communication.exceptions.CommunicationException: hostname 'My Computer Name' unknown; Destination data=System Id [client=800, language=EN, systemConfiguration=Name={null} | SystemId=System ID | Host=Server | Server=null | SystemNumber=null | MessageServerService=18152 | Description=null | Group=PUBLIC | Origin=null | PreferredLanguage=null | PartnerName=null | SNCType=SNC_DISABLED | MessageServer=lServer | PreferredClient=null | PreferredUser=null | Router=null, user=User]
