Leginon

h1. An example of working port-forwarding configuration

h2. (Paraphrased from description by Brian J. Gibbens)

For those interested, this is how I set up Leginon on the TF20 in the

Kornberg lab at Stanford with the following configuration:

Local network (192.168.xxx.xxx in this example) can not be accessed directly through

institute network that has internet access before port forwarding.

h2. The computer hosts involved in this port-forwarding configuration:

# *ScopePC* (Windows) - The computer controlling the microscope

** connected only to local network

** Static local IP addresses (192.168.200.99 in this example) is set to this host.

# *SupportPC* (Windows) - The computer provided by FEI to protect *ScopePC* while allow RAPID system support from them through internet.

** Two network cards are on this computer.

** Local network Static IP address (192.168.200.100 in this example)

** Outbound institute network Static IP address (137.131.204.250 in this example)

# *LeginonMain* (Linux) - The computer that runs Leginon processing/database/storage.  Could be multiple.  Here assumes just 1

** Institute network Static IP address (137.131.204.500 in this example)

*Ethernet cables should be connected like in the figure above.*

h2. TCP/IP Gateway Settings on *ScopePC*

This should be set to the local IP address of the *SupportPC* like this:

h2. Firewall settings on *SupportPC*

** allow communication to both *ScopePC* and *LeginonMain*.

h2. Hosts file addition if needed

--Appropriate IP addresses and hostnames added to the hosts files

(C:/WINDOWS/System32/drivers/etc/hosts.txt on Windows PC's and

/etc/hosts on Linux).

* On *ScopePC* - list both hostnames of *SupportPC* and *LeginonMain*

* On *SupportPC* - list both hostnames of *ScopePC* and *LeginonMain*

* On *LeginonMain* - list only hostname of *SupportPC* since all communication from *ScopePC* to *LeginonMain* through *SupportPC* will appear to

come from *SupportPC*

h2. Install port forwarding program AUTAPF which allows needed host/port specification on *SupportPC*

Below is a screen shot of how we configured AUTAPF for a test at NRAMM.  The hosts are represented as follows:

localdefcon3:  the microscope PC running leginon client/launcher

defcon3:  the support PC with AUTAPF installed

amilab7:  the remote linux running main leginon
