VisIt Host File Help

[jameskress]

We have a system that both ParaView and VisIt were unable to connect a client server session to, for reasons the admin team was unable to explain. We are now replacing that system, and HPE is helping resolve the connection issues for ParaView on that machine. We finally have system settings fixed in such a way that we were able to craft a ParaView pvsm file that allows an interactive session.

I would like to translate this pvsm into a VisIt host file, but am struggling, as it seems quite different from the other host files we have. On the ParaView docs our new pvsm most closely matches "7.5.17. Case Seventeen: Secured Reverse Connection from a Server trough SSH tunnel"

The bit I am struggling with is how I can specify the address of the port forwarding call, as it is different from the host name. When looking at the logs it seems that potentially if I can change the -host that VisIt uses I might be able to get the reverse connection to establish. sw/vis2/shaheen3.2024.03/visit-src-3.3.3/install/3.3.3/linux-x86_64/bin/engine_par -dir /sw/vis2/shaheen3-visit -forcestatic -idle-timeout 480 -noloopback -sshtunneling -host login5 -port 28112 -key d7751bcec9f78abb4309

Currently I am able to connect to the system and the vcl and mdserver start fine. I select a file and launch a job, but the job it unable to connect back. The ParaView pvsm that works on this system is below. Any ideas on how VisIt can support Case 17 from the ParaView docs?

Cheers,
