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

building network that has internet access before port forwarding.

# TECNAI_COMPUTER (Windows XP) not connected to network, but connected

directly to Tecnai F20 and to TF20SUPPORT_COMPUTER (Windows XP) through two separate network cards. Static local IP addresses (168.128.xxx.xxx in this example) should be set on these. Local IP address of the TF20SUPPORT_COMPUTER 168.128.200.100 in the example figure) was added to the TCP/IP settings on the network on the TECNAI_COMPUTER that connects to the TF20SUPPORT_COMPUTER.

# TF20SUPPORT_COMPUTER has two network cards and two IP addresses.  One is connected to building network, the other is connected to the TECNAI_COMPUTER as mentioned above.

# WEBSERVER_DATABASE_COMPUTER (Suse 11.1 Linux) with MySQL, PHP, and Samba share for drive mapping on PC's. Connects to TF20SUPPORT_COMPUTER through building network.

--Norton firewall settings on TF20SUPPORT_COMPUTER configured to allow

communication to both '1' and '3'.

--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). '2' and '3' listed in hosts file on '1'; '1' and

'3' listed in hosts file on '2'; and '2' only listed in hosts file on

'3' since all communication from '1' to '3' through '2' will appear to

come from '2'.

--Program for port forwarding (AUTAPF) installed on TF20SUPPORT_COMPUTER

and set up to forward all appropriate ports to IP address of the router

on TECNAI_COMPUTER that connects to TF20SUPPORT_COMPUTER.
