The Eternal Value of Privacy

This article, written by Bruce Schneier, was in Wired Magazine in 2006. Even though time has passed, this is the best explanation as to why privacy - my privacy and your privacy - is so very important. I’ve always had a hard time explaining it, and when I reference this article, I always have a hard time finding it again.

The most common retort against privacy advocates — by those in favor of ID checks, cameras, databases, data mining and other wholesale surveillance measures — is this line: “If you aren’t doing anything wrong, what do you have to hide?” Continue reading ‘The Eternal Value of Privacy’ »

Cisco VPN - Error 51: Unable to communicate with the VPN subsystem

Running Cisco VPN on OS-X I would get “Error 51: Unable to communicate with the VPN subsystem” whenever I would try to connect. I tried rebooting, moving from Wireless to Wired (and rebooting in between), and nothing would work. However,

sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart

seems to fix the issue.

Sending mail from CentOS on Slicehost

When I first set up CainManor on slicehost, e-mail wasn’t working. The solution, based on this thread, was to install postfix.

apt-get install postfix  -Install postfix

edit /etc/postfix/main.cf

mydomain = cainmanor.com
myorigin = cainmanor.com
mynetworks_style = host

service postfix start -start the service to see if it works as expected.

chkconfig –list postfix - make sure it will start on boot.  The default install takes care of this

Considerations when moving SAV CE v10 from UNC to HTTP updates

I didn’t see this documented anywhere, but you have to create the following MIME types on your web server when you move to HTTP updates as your transport.

IS Manager -> <your server> -> Default Web Site -> Your Directory -> properties.

Go to http header -> MIME Types. Add

.m25 application/binary (for v10)
.x86 application/binary (for v8 & v9)

Easy way to ping a range of IP Addresses

nmap -sP 10.1.1.0/24

When I need to find an open IP, this is a decent way to do it. I wish there were a way to find IPs that don’t respond, but this works for now. This won’t work if your network bans ICMP traffic, or your host doesn’t respond, but is alive.
