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".

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)..
