Here is how to start VNC from command line on your macintosh (say, via ssh) and then connect to your Macintosh from a Windows VNC client
Server side (SSH to your mac):
Step 1: -- set privs
Badabing:~ rob$ sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -configure -allowAccessFor -allUsers -privs -all
Starting...
Setting allow all users to YES.
Setting all users privileges to 1073742079.
Done.
Step 2: -- Allow VNC clients
Badabing:~ rob$ sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -configure -clientopts -setvnclegacy -vnclegacy yes
Starting...
Set the client options.
Done.
Step 3: -- Set VNC password (change it at the end of the line (i.e. don't use supersecret))
Badabing:~ rob$ sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -configure -clientopts -setvncpw -vncpw supersecret
Starting...
Set the client options.
Done.
Step 4: -- Restart service
Badabing:~ rob$ sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -restart -agent -console
Starting...
Stopped ARD Agent.
Stopped VNC Privilege Proxy
Stopped RFB Register MDNS
Done.
Badabing:~ rob$
Step 5: -- Client side config
Windows (Client Side)
I installed the tightVNC viewer.
Enter IP address in the VNC Server field. Click "Options" Change Encoding to Hextile. Click ok.
Click Connect.
Enjoy.

Create ISO CD/DVD image using OSX
Create ISO CD/DVD image (.iso) with Mac OS X
1. Insert CD/DVD source
2. Fire up a Terminal, you can then determine the device that is you CD/DVD drive using the following command:
$ drutil status
Vendor Product Rev
MATSHITA DVD-R UJ-835E GAND
Type: DVD-ROM Name: /dev/disk1
Cur Write: 8x DVD Sessions: 1
Max Write: 8x DVD Tracks: 1
Overwritable: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Free: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Used: 364:08:27 blocks: 1638627 / 3.36GB / 3.13GiB
Writability:
Book Type: DVD-ROM
3. Umount the disk with the following command:
$ diskutil unmountDisk /dev/disk1
Disk /dev/disk1 unmounted
4. Create the ISO file with the dd utility (may take some time):
$ dd if=/dev/disk1 of=file.iso bs=2048
5. Test the ISO image by mounting the new file (or open with Finder):
$ hdid file.iso
6. The ISO image can then be burnt to a blank CD/DVD.

Cisco VPN Error 51 workaround
Cisco VPN Error 51 workaround
Macintosh OSX
Have you have ever encountered the following error when launching the Cisco VPN Client on your mac:
Error 51: Unable to communicate with the VPN subsystem.
Please make sure that you have at least one network interface that is currently active and has an IP address and start this application again.
The problem stems from another network interface (like firewire or a third party network interface such as VMware or Hamachi) stepping on the cisco VPN interface.
Over the years, I have worked around this problem in several ways... all of which are not as graceful as:
sudo SystemStarter restart CiscoVPN
Anyway, just wanted to save you reboots and or frustration should it ever come up for you...
You could even make an alias out of it by add the following line to your .bash_profile
alias resetcisco='sudo SystemStarter restart CiscoVPN'
then (on next login) you could just type "resetcisco".

Put two IP addresses on one NIC
Here is how to have two IPs using one network card in linux.
In the directory /etc/sysconfig/networking/devices
Create the following new file by typing "vi ifcfg-eth0:0"
DEVICE=eth0:0
BOOTPROTO=none
IPADDR=192.168.1.23 # your second IP
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
TYPE=Ethernet
ONPARENT=yes
Next, in the directory /etc/sysconfig/networking/profiles/default
create the same file again by typing "vi ifcfg-eth0:0"
DEVICE=eth0:0
BOOTPROTO=none
IPADDR=192.168.1.14 # your second IP
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
TYPE=Ethernet
ONPARENT=yes
now, bounce networking with "service networking restart" and use ifconfig to see if the net interface shows up...

Xbox360 ushare
Here's how to get ushare to work with your xbox360:
This will allow you to stream video (movies) form your ubuntu box to your xbox360.
sudo apt-get ushare
sudo gedit /etc/ushare.conf
Verify (or change 3 things):
(your interface)
USHARE_IFACE=eth0
(the directory with your media)
USHARE_DIR=/home/user/media
(enable xbox support)
USHARE_ENABLE_XBOX=yes
Save the file...
We need to add -x to the ushare daemon when it is launched...
so edit:
sudo gedit /etc/rc3.d/s20ushare
Near the top, add the following line:
USHARE_OPTIONS=-x
save the file...
then bounce the service.
sudo invoke-rc.d ushare stop
sudo invoke-rc.d ushare start
(in my experience, if your use sudo invoke-rc.d ushare restart, it will respawn too quickly... you can add a sleep statement in the restart script... or just to what I did above)
Restart your xbox360... enjoy.
