Hi Ryu

Thanks for your reply

so we did do that - it seems that the path to MIDASYS needs to be defined on the localhost too ? Anyhow the program does not run complaining that it is unable to read from the online database -

[HGUIExample,ERROR] [ROMEPrint.cpp:177:ROMEPrint::Error,ERROR] Can not read run status from the online database

So the ODB cannot be read through this port ? Do you have an example of running ROME through an ssh tunnel via an intermediary (gateway) machine ?

many thanks
Farrukh

Hello,

I think you need to use SSH port forwarding,

On C, you open a terminal and type a command like,
   ssh -L 21175:A:1175 B
1175 is the MIDAS server port number.
For avoiding the connection being terminated, you may better to type a command to keep the communication, for
example,
   top

Then, on C, you configure ROME to connect to localhost and port number is 21175, and start the ROME analyzer.
