Remote Logon button in SM59 does not work

Known problems:

189077 The remote login in SM59 does not work
51367 RFC logon under different user or client



Clicking on the Remote Logon button in SM59 returns no response:




It is necessary to ensure that the source and destination hosts should be able to successfully perform the two-way hostname<->IP lookup for the other host that is involved in the RFC connection.


Problems have occurred whereby the response from the RFC-call receiver to the sender gets stuck.

The sending system determines his own IP-address via the command'hostname' on operating system level. This IP-address is send within the RFC protocol to the receiving system. NAT and other IP-address translations in the firewall are not working on RFC level. The receiver sends a response back to this IP-address, so this IP-Address has to be known on receiver side.
Solution:

• Don't use IP-address translations in your firewall. Use firewall and saprouter instead, if possible
• Define a IP-address routing on the receiving system to route the IP-address to the correct address.
