Hana Express edition - Error connect to R Rserve

Hi,

after installing the HXE environment I wanted to set up the R connectivity according to

http://go.sap.com/developer/how-tos/hxe-connect-hxe-using-r.html

The R installation is done on a Opensuse 13.1 system (which is not supported) but all installation and configuration steps look good, except remote connection to Rserve.

Test after starting R serve on local Rservelhost:

telnet localhost 30020 -> connection seems ok

output:

Trying ::1...

telnet: connect to adress ::1: connection refused

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

Rsrv 0103QAP1

____________

now from a remote system:

telnet rservehost 30020 -> connection refused

ssh standard port is open and remote logon possible

Firewall on the Rserve system is stopped.

Anybody who can advice which settings on the Rserve system need to be adjusted to connect the Hana box to the Rserve box?

Thanks and kind regards,

Axel

for whatever reasons Rserve didnt start remote enabled. enhancing the start command with --RS-enable-remote solved the problem.
