Using local network card

I decided to connect the ROC directly to the second 1 Gigabit ethernet card on the host in order to avoid setting up a firewall which makes our sys admin guys happy and allows CODA to work.

I had to tell the ROC to alias the new host names in the boot script

so in the file CODA/bootscripts/roc1.boot

I added the line

hostAdd "daq1","10.1.1.1"

You can do this on the roc as well and then on the ROC you can check the lookup tables using the command

-> hostShow                                                                     
hostname         inet address       aliases                                     
--------         ------------       -------                                     
localhost        127.0.0.1                                                      
roc1             10.1.1.2

value = 0 = 0x0

ROC won't load VxWorks Kernel

If you have anout output to stdout from a .cshrc or .tcshrc login script then the ROC will have trouble loading the kernel.

I ran into this one when I deciced to "source CODA/setup" in order to define my CODA environmental variables when I log in. The setup script did a "echo" and this caused the ROC to stop loading the kernel. When I was watching via minicom all I saw was the word "Loading...".
