Setup NFS server on Ubuntu:
   . sudo apt-get install nfs-kernel-server
   . Create a folder for sharing
      . mkdir PATH_TO_SHARE
      . chmod -R 777 PATH_TO_SHARE
   . Edit /etc/exports
      . sudo vi /etc/exports
      . add following line and save
         PATH_TO_SHARE *(rw,sync,insecure,no_root_squash,no_all_squash)
   . Refresh updated /etc/exports
      . sudo exportfs -r
   . Restart NFS server
      . /etc/init.d/nfs-kernel-server restart
   . Check shared NFS folders
      . showmount -e localhost


Connect to NFS server on Ubuntu from Mac OS X
[Finder]
   . Cmd + K (Finder -> Go -> Connect to Server )
     . nfs://IPOfUbuntu:/PATH_TO_SHARE
[Terminal]
   . Check what folders have been shared
      . showmount -e IPOfUbuntu
   . Create a mount point
      . mkdir MOUNT_POINT
   . Mount nfs to local MOUNT_POINT folder
      . sudo mount -o resvport,rw -t nfs IPOfUbuntu:/PATH_TO_SHARE MOUNT_POINT

How to check the CPU model of your Mac

Open the terminal, run the following command

sysctl -n machdep.cpu.brand_string

ffplay rtsp command

ffplay -i rtsp://url

To force ffplay to use TCP, add "-rtsp_transport tcp" right after ffplay.
E.g. ffplay -rtsp_transport tcp -i rtsp://url

Sharing folders between VMware host and guest O.S.

1. Install VMware Tools. See http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1022048 and http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1022525
     . Virtual Machine -> Install VMware Tools
           sudo mkdir /mnt/vmtools
           sudo mount /dev/sr0 /mnt/vmtools
           cd /mnt/vmtools
           tar zxvf VMwareTools-x.x.x.tar.gz -C /tmp
           cd /tmp/vmware-tools-distrib
           sudo ./vmware-install.pl -d
           sudo reboot

2. Configure share folder
     . Go to settings of the guest VM -> Sharing
           Setup the sharing folder

3. The location of the shared folder will be in /mnt/hgfs or /media/psf/
