Run 32 bit compiler on 64 bit Ubuntu Server 14.04

Firstly, install 32 environmrnt;

         sudo apt - get install libc6 : i386

Before installing ia32-libs with the source:

sudo - i
cd / etc / apt / sources . List . d
echo "deb http://archive.ubuntu.com/ubuntu/ main restricted universe multiverse raring"  > ia32 - libs - raring . List
apt - get Update
apt - get install ia32 - libs
rm ia32 - libs - raring . List
apt - get Update

When installing gcc to compile some libraries need:

sudo apt - get install gcc - multilib

Problem on Wireshark Dissector installation

After run make, the make command output is ( in 'openflow/utilities/wireshark_dissectors/openflow' directory):

  
 In file included from /usr/include/glib-2.0/glib/galloca.h:34:0,
                  from /usr/include/glib-2.0/glib.h:32,
                  from packet-openflow.c:19:
 /usr/include/glib-2.0/glib/gtypes.h:34:24: fatal error: glibconfig.h: File or directory ot found
 compilation terminated.
 make: ** [packet-openflow.o] Erro 1

Solution:

openflow at ubuntu:~$ find /usr -name glibconfig.h
/usr/lib/i386-linux-gnu/glib-2.0/include/glibconfig.h

On Ubuntu, adding `pkg-config --cflags glib-2.0` (note backquotes), 

or the output of said command, to CFLAGS, should fix it. Otherwise, just make sure you pass in the correct include directory.

i.e. 

-I/usr/include/glib-2.0

-I/usr/lib/x86_64-linux-gnu/glib-2.0/include

add above 2 lines in Makefile (openflow/utilities/wireshark_dissectors/openflow), under CFLAGS

Accessing file in VM (ubuntu) from ESXi Datastore

1. Select the files to be moved from local device to ESXi server datastore.
   
   
   
2. Make sure that the files are .iso format
3. Upload to ESX. data-store
   
   
   
   
4. Then, goto VM (Ubuntu)
5. Select the CD/DVD and ESXi datastore, where .iso file is located
   
   
   
6. In the datastore, select on .iso file
   
7. Now, goto terminal in Ubuntu

                                               mount /dev/cdrom /mnt/cdrom

Now files located in .iso file will be available to Ubuntu.

Collecting SDN forwarder port status at SDN Controller

This is to gather the port status of every switch or forwarder at SDN controller.

Register the port_stats_in function:

        ...


def handle_portstats_in(self, dpid, stats):

    Parameters in stats: port_no, rx_packets, tx_packets, rx_bytes, tx_bytes, rx_dropped, tx_dropped,       rx_errors, tx_errors, rx_frame_err, rx_over_err, rx_crc_err, collisions
    """
    print "Port Stats received...."
    print "Port stats in from datapath", longlong_to_octstr(dpid)[6:]
    for item in stats:
print '\t',item['port_no'],':',item['tx_packets'],':',item['rx_packets']

Adding Hard Disk to ESXi 5.1 Server

The ESXi 5.1 doesn't support RAID configuration, there for better to use RAID 0 for minimum number of hard disk and add the remaining hard disk through vSphere Client.

The steps is as follows:

host > storage > add storage > Disk/LUN > next
