How To
Recover your Mac after Software Update freeze PDF Print E-mail

If you've been amongst the many thousands of Mac users who suffered a system freeze or crashes after a recent update, there is hope. Most of the news report centered around users who upgraded from 10.5.5 to 10.5.6. As I am still using 10.4.11, I will provide one way to recover your system if you've suffered the Apple version of the Blue Screen of Death.

I had used the typically solid Software Update mechanism to acquire the latest security fixes for my wife's Mac Book. 126MB later, and a quick reboot, and...nothing...watch the little wheel spin for hours...grrr.

Steps taken:

1) Reboot the Mac to the install CD that you darned well better have. ;-) Should be labeled Mac OS X Install Disk 1.

2) On another system download the appropriate stabdalone update package. In my case, as we have an Intel-based Mac Book running 10.4.11 I grabbed Security Update 2008-008 (Client Intel). Once downloaded, I put the package file on a USB drive and headed back to the Mac.

3) Open Terminal on your Mac.

4) Assuming your harddrive is /Volumes/Macintosh\ HD and the security update on the USB drive is /Volumes/Security\ Update\ 2008-008/SecUpd2008-008Intel.pkg execute the following command via Terminal:

/Volumes/Macintosh\ HD/usr/sbin/installer -pkg /Volumes/Security\ Update\ 2008-008/SecUpd2008-008Intel.pkg -target /Volumes/Macintosh\ HD

5) Reboot and you should be good to go.

 

 

 
 
Install VMWare on Ubuntu PDF Print E-mail

Installing VMWare on Ubuntu can be a pain in the butt. Here a few steps that may help.

Updated 11/6/08 for VMWare Server 1.07 on Ubuntu Intrepid Ibex running the 2.6.27-7-generic kernel.

No need to rewrite what is already well documented. See VMWare Server 1.0.7 on Ubuntu 8.10 "Intrepid" (2.6.27.-7-generic)

Sometimes after the upgrade you may need to run sudo apt-get install linux-headers-`uname -r` where uname -r has been run to give you your running kernel.

These steps are best for 64-bit installations.

We'll assume you've downloaded VMWare Server 1.07, unpacked it, and changed to the vmware-server-distrib directory.

1) Install xinetd and ia32-libs
sudo apt-get install xinetd ia32-libs

2) Run the VMWare installation program.
./vmware-install.pl
The installation script automatically runs the belwo mentioned config script but if your installation effort fails, you may need to run it again.
./vmware-config.pl


3) Execute vmware as root or normal user; you may end up receiving the following libgcc error.

vmware
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_3.4' not found (required by /usr/lib32/libcairo.so.2)
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib32/libstdc++.so.6)
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_3.4' not found (required by /usr/lib32/libcairo.so.2)
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib32/libstdc++.so.6)
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_3.4' not found (required by /usr/lib32/libcairo.so.2)
/usr/lib/vmware/bin/vmware: /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib32/libstdc++.so.6)

4) For the easy fix, rename libgcc_s.so.1:

cd /usr/lib/vmware/lib/libgcc_s.so.1
sudo mv libgcc_s.so.1 libgcc_s.so.1-bak
This forces VMWare to use libgcc_s.so.1 from /usr/lib rather than the VMWare version.

5) Run vmware again, this time error free.

Updated 1/7/10.

James Affeld'a Snort rule clinic is here.

In addition, Marty Roesch's Writing Snort Rules is a great starting point.

Both are a bit dated but are extraordinarily good for developing the fundamentals.
