= Setting up NetFPGA hosts: Ubuntu 10.04 = 
Current Ubuntu NetFPGAs run Ubuntu version 8.04 and !OpenFlow ver. 1.0. Here we try to move to newer distributions w/ !OpenFlow Ver. 1.0. The hardware we use here is the NetFPGA cube, another version of the NetFPGA pre-built solution. A user named 'test' with root privs was added for this purpose.    

Setup of the NetFPGA using earlier distributions can be found in the Diaries.   

'''Linux distro:''' [[BR]]
Ubuntu Server 10.04, w/ xfce4 WM [[BR]]
kernel: 2.6.32-21-generic-pae 

'''Packages:''' [[BR]]
NetFPGA base 2.1.0 [[BR]]
Tunneling OpenFlow NetFPGA 1.0.0

'''Host info:''' [[BR]]
node1-1: 192.168.202.8  [[BR]]    
node1-2: 192.168.202.164    

=== Installing Ubuntu. ===

1. set boot priority of CD drive to 1st
2. If desktop edition, boot as a live CD and install from there. Trying direct install just resulted in the system starting up BusyBox (9.10) or just proceeding to live CD Mode (10.04). Server edition can be installed directly w/out issues.   

=== Setup: NetFPGA drivers. ===
'''1. dependencies.'''[[BR]]
There is an updated dependency list:

  * ncurses-dev
  * libnet1-dev
  * libxml-simple-perl
  * libio-interface-perl
  * liblist-moreutils-perl
  * liberror-perl
  * libnet-rawip-perl
  * sun-java6-jre
  * sun-java6-jdk
  * libpcap0.8-dev

in 10.04, sun-java6-jre, jdk are obsoleted and moved to the partner repository. This repository can be added w/ the following (ref: https://help.ubuntu.com/community/Repositories/CommandLine):

 1. copy "deb http://archive.canonical.com/ lucid partner" sans quotes to /etc/apt/sources.list
 1. run apt-get update. 
 1. run apt-get as usual for the packages. 

'''2. Kernel memory allocation. '''[[BR]]
Ubuntu versions beyond 8.04 (assume anything w/ kernels beyond v 2.6.28) use GRUB 2. GRUB 2 gets rid of menu.lst, so kernel memory must be allocated via the following method (ref. http://ohioloco.ubuntuforums.org/showthread.php?p=8229620):

Add "vmalloc=512m" to the following line in /etc/default/grub so it looks like this: 
{{{
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=512m"
}}}
Then run `update-grub` to regenerate /boot/grub/grub.cfg with the new parameter (you never want to modify grub.cfg directly).

'''3. Symlinks.'''[[BR]][[BR]]
The steps are the same as before...Make sure to slap things into /usr/lib before linking. 

'''4. Edit files.'''
 * edit "usleep 250" to "sleep 0.00025" in /test_loopback_drop/run.pl 
 * edit /home/netfpga/NF2/projects/router_kit/sw/rkd.cc to include limits.h

'''5. Setting Variables.'''[[BR]]
Scripts seemed broken, so manually export'd all of them. Specifics of variables pulled from README in base package root directory.  
{{{
export NF_ROOT=/home/test/netfpga (wherever your netfpga base files are) 
export NF_DESIGN_DIR="${NF_ROOT}/projects/reference_router" (whatever directory project is in)
export PERL5LIB="${NF_DESIGN_DIR}/lib/Perl5:${NF_ROOT}/lib/Perl5:${PERL5LIB}" (from ${NF_ROOT}/bin/nf_profile)
}}}

'''6. Moment of truth.'''[[BR]]
`make` then `make install clean`. 

check for nf2 module with `lsmod | grep nf2`: 
{{{
nf2                    13425  0 
}}} 
and for nf2cn, n=0:3 with `ifconfig -a`.
