Hi,

I’m trying to set up two render nodes – the 1st machine is a Windows 7 machine and the 2nd machine is a Linux/Ubuntu 12.04 machine. I've had Maxwell installed on the Windows machine for a while now and it’s been running without any problems. Maxwell and the Maxwell network components seem to be installed correctly on the Linux machine and start up without any errors. I’m trying to use the Linux machine as a render node and run the Network Manager and Monitor on the Windows machine. When I start the Network Monitor, it doesn’t see the render node on the Linux machine. I can ping each machine so there is basic network connectivity.

Not sure what I need to do next to have the Windows based Network Monitor see the Linux render node. Any help would be greatly appreciated!

Thanks,
Mike

do you have set an inbound fw rule on the win machine?
also make sure the port for communication (preferences in node/monitor and manager) is set to the same number

A common cause is a firewall running on the Linux box. I think that the default Ubuntu installation sets up a firewall and closes everything except ports 80 (http) , 22 (ssh-sftp) and maybe another one or two. The maxwell network system uses ports from 45454 to 45474 (user selectable in Preferences). Check that these ports are not being used by any service (see the contents of /etc/services and check that port 45454 isn't used).

Thanks Polynurb and Miguel!

I disabled the Linux firewall (machines are not connected to the Internet) and everything seems to be working. Interestingly, the Ubantu desktop guide says the firewall is disabled by default…

I'm new to Linux so lots to learn!
