SuperBox Troubleshooting: Onsite Networks

Onsite Network settings troubleshooting. For example, some sites block internet access of client PCs or have different subnets, etc.

Before proceeding to troubleshoot Offload Calculation Server connectivity issues, verify the following:

  • The Offload Calculation Server is powered on (connected to a power supply with the power button on).

  • The Offload Calculation Server is connected to the LAN (Local Area Network) or to a local Router (not hub).

If the Offload Calculation Server is powered on but does not seem to be powered, there might be a hardware failure. If the Offload Calculation Server power light is not on, or the Offload Calculation Server cooling fan doesn’t work, contact your local Cimatron Provider or Reseller for further instructions.

If Offload Calculation Servers are not available due to onsite networks settings, for example some sites block internet access of client PCs or have different subnets, etc., try checking the following:

Client or Offload Calculation Seat has a Non-Microsoft Windows Firewall

Client or Offload Calculation Seat has Blocked Internet Communications

Connection through Wireless

ESET NOD32 Antivirus

Client or Offload Calculation Seat Connection Does Not Support TCP/IPv4

Client and Offload Calculation Seat are connected on different subnets

Network does not support Dynamic IP

Client or Offload Calculation Seat has a Non-Microsoft Windows Firewall

Disable the client's personal firewall (the Microsoft Windows firewall and the network firewalls are handled automatically).

If Offload Calculation Seats are available, you need to allow access on the personal firewall by adding the following port numbers to the firewall "Exception" list:

  • HTTP-In 36127 (System)

  • UDP-In 36128 (CimRemoteRedConsolHost.exe)

  • UDP-In 36129 (CimRemoteWorker.exe)

Client or Offload Calculation Seat has Blocked Internet Communications

General requirements:

  1. The Offload Calculation Seat should be in the Domain.

  2. It is important to have enough disk space on the Offload Calculation Seat disk. See the Offload Calculation Server - Hardware-Software Requirements file that can be found on the Cimatron installation media.

On the client computer, create the file SuperBoxList.dat in the data directory listing the IPs of the Offload Calculation Seats.

Connection through Wireless

The Offload Calculation Seat must be connected directly to the router. It has no wireless connectivity.

A client may connect wireless to the network.

For performance reasons, it is strongly advised that the Offload Calculation Seat is connected with the fastest connection method.

When using a wireless network with slow connectivity (below 10 Mbps), operations may end unsuccessfully due to interruptions in data transfer.

 

ESET NOD32 Antivirus

Some users have reported issues using the Offload Calculation Seat if they are using older versions of the ESET NOD32 Antivirus software.

The ESET NOD32 Antivirus program has a problem handling basic HTTP data that is moved across the network between a client and an Offload Calculation Seat, since the antivirus program continuously scans the traffic. This problem results in a very slow connection, up to the point where calculations abort after one minute. To solve this issue, uncheck the HTTP Scan option and restart all Cimatron processes.

Client or Offload Calculation Seat Connection Does Not Support TCP/IPv4

Verify that the TCP/IPv4 option is set.

From the Windows Control Panel, select Network and Internet > Network and Sharing Center. Press the Properties button for the connection you are working with.

Verify that this option is checked for the used connection.

Client and Offload Calculation Seat are Connected on Different Subnets

The client and Offload Calculation Seat must be connected to the same subnet.

If the client has more than one network connection (for example, LAN, Wi-Fi, LAN2), verify that the client has an active connection on the same subnet as the Offload Calculation Seat. Usually different connections are connected to different subnets.

If Offload Calculation Seats are not available, they may be connected outside of the network firewall (or on a different VLAN).

Network does not support Dynamic IP

If the network does not support dynamic IP or if the router cannot be configured to allow the Offload Calculation Seat to get a fixed IP, set the Offload Calculation Seat with a static IP.

If the Offload Calculation Seat is a Cimatron device, follow the next steps to configure the Offload Calculation Seat with a static IP:

Prepare a file by the name StaticIP.dat.

The file should include the following data in the exact format:

IP       = 10.1.1.1

Subnet   = 255.255.255.0

Gateway  = 196.10.100.1

Move/copy the file to the root folder of a USB flash drive and connect it to the Offload Calculation Seat.

Restart the Offload Calculation Seat.

To reset the Offload Calculation Seat back to be DHCP enabled, place the string DHCP in the StaticIP.dat file, and restart the Offload Calculation Seat.

The Cimatron SuperBox as a Software (SBaS) can be configured manually to a static IP.

Note: For the Cimatron device, the USB should be a 'simple' 2.0 USB that does not require special driver installation.

Some functionality may be dependent on the product package. Contact your Reseller if you require a license.
