The local port 21175 may be too large, please replace 21175 by, for example, 8175.
You can specify the host name and the port number in your config XML for your ROME program like, <Online>
<Host>localhost:8175</Host>
</Online>
Can you connect the MIDAS experiment from the host B with using other midas applications, e.g odbedit ?
Can you try odbedit -h A -e EXP (replace EXP with your experiment name)
If you can not connect, I think there is a problem which is not related to ROME.
Can you also check if you can connect the MIDAS experiment from the host C with using other midas applications, e.g odbedit, after establishing the SSH tunnel ?
Can you try odbedit -h localhost:8175 -e EXP (replace EXP with your experiment name)

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

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.
