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...

[root@mail default]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:13:72:52:3A:2C

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.

OSX Leopard hamachi auto start

For those of you waiting to have a Leopard compatible gui for hamachi... This should help for now. This will get you up and running with the command line.


The following should start tuncfg on boot (as root) and then hamachi will start up on login.


First install the leopard tun/tap drivers.

You need to make sure that Xcode tools are installed (you can install them from your leopard disc -- find them under optional installs) or them from Apple's Developer connection. If this is not installed you will get an error when attempting to use "make".

You will them be able to install hamachi.

After you get hamachi working properly from the command line.... use the follow (very rough) steps to get it to auto-start for you.




Here's what I did:



created directory:

sudo mkdir /Library/BootScripts

created file:

sudo vi /Library/BootScripts/loadtuncfg.sh

filecontents of loadtuncf.sh

----- snip -----

#!/bin/bash

sleep 30
/usr/sbin/tuncfg

------- end of snip ------

sudo chmod 755 /Library/BootScripts/loadtuncfg.sh
(file is owned by root:admin on my machine)


created file:

sudo vi /Library/LaunchDaemons/com.loadtuncfg.launchd.loadtuncfg.plist



file contents of com.loadtuncfg.launchd.loadtuncfg.plist:


-------snip---------

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
 <dict>
  <key>Label</key>
  <string>com.loadtuncfg.launchd.loadtuncfg</string>
  
  <key>KeepAlive</key>
  <false/>
 
  <key>ProgramArguments</key>
  <array>
   <string>/Library/BootScripts/loadtuncfg.sh</string>
   <string>run</string>
  </array>

  <key>RunAtLoad</key>
  <true/>
 </dict>
 </plist>

----------end of snip -----


All of the above should start tuncfg on boot (after 30 sec delay).




Now to start hamachi after local user login...

Make sure to change "yourusername" to the user that you use. Even in the .plist file below.




created directory: (notice not using sudo)

mkdir /Users/yourusername/Library/LoginScripts/

created file: (notice not using sudo)

vi /Users/yourusername/Library/LoginScripts/loadhamachi.sh

file contents of loadhamachi.sh:

-------- snip --------

#!/bin/bash
sleep 40
hamachi start
hamachi login
hamachi go-online yournetworkname

---- end of snip -----

chmod 755 /Users/yourusername/Library/LoginScripts/loadhamachi.sh
(file is owned by yourusername:yourusername)

created directory: (notice not using sudo and directory may already exist)

mkdir /Users/yourusername/Library/LaunchAgents


created file: (notice not using sudo)

vi /Users/yourusername/Library/LaunchAgents/com.loadhamachi.launchd.loadhamachi.plist

file contents of com.loadhamachi.launchd.loadhamachi.plist:

--- snip ----

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
 <dict>
  <key>Label</key>
  <string>com.loadhamachi.launchd.loadhamachi</string>
  
  <key>KeepAlive</key>
  <false/>
 
  <key>ProgramArguments</key>
  <array>
   <string>/Users/yourusername/Library/LoginScripts/loadhamachi.sh</string>
   <string>run</string>
  </array>

  <key>RunAtLoad</key>
  <true/>
 </dict>
 </plist>

------ end of snip ------

file is 644 (as created and owned by youusername)


Now reboot...

tuncfg will load in 30 seconds after boot up..

hamachi will load 40 seconds after login.. (delayed longer to ensure that tuncfg loaded)..

Dreambox tricks

For a dreambox 500 et al:


Setup the dreambox CDK environment with these steps. I used RHEL 5 but I am sure the fedora or others would work fine. Prerequisites here can be found here: cvs.tuxbox.org/cgi-bin/viewcvs.cgi/tuxbox/cdk/doc/INSTALL.en?rev=HEAD


export CVS_RSH=ssh
cvs -d anoncvs@cvs.tuxbox.org:/cvs/tuxbox -z3 co -P -rdreambox .

cd cdk
chmod 755 prepare
./prepare dm500
make checkout
make core
(when it bombed on nptl-0.60.tar.bz2)
cd Archive
wget http://ftp.devil-linux.org/pub/devel/sources/1.2/nptl-0.60.tar.bz2
cd ..
