Hello,

I installed Houdini20.5..332 on Rocky Linux 9.4 and when I try to start hkey from the terminal, it starts but I get the following warning: "License server is not running".

I have already installed the Linux packages described in the following page, but the warning still appears.

Linux package requirements for Houdini 20.5 [www.sidefx.com]

I think you don't have the appropriate service running.
Also when installing the software and the licence server, Houdini had to create the directory /usr/lib/sesi.

sudo systemctl status sesinetd.service

Thanks for your reply.

I recall that I once experienced a similar problem to the link below when using Houdini 19.5 on Rocky Linux 9.3.

At that time, Houdini did not support Rocky Linux yet, but I found that Houdini 20.5 supports Rocky Linux, so I am in the process of trying it out.

Almost solved..

I executed the following command

sudo systemctl enable sesinetd.service
sudo systemctl daemon-reload
sudo systemctl start sesinetd.service

Now I can run hkey, but even after installing the license, I get a DIAGNOSTIC message "Could not open the license file", so I have to give access to the license file, and Houdini 20.5 will now run on Rocky Linux 9.4.
