dhcpd.conf how to secure so only known and allowed clients will be given dhcpd IP address leases
It's really simple and just a matter of the following line within the subnet declaration.

range 10.25.20.11 10.25.20.254;

Asterisk Agent Login Problem
Asterisk Agent Login ProblemUsing the AgentCallbackLogin function I couldn't login
I knew I had my agents setup properly in agents.conf so why couldn't I login?
The reason is because agents.conf was missing the [b:994d7a34af][agents][/b:994d7a34af] context!
I just added [agents] above the existing agent declarations and then I was able to login as expected.
It took a lot of figuring out and reading though!........

Using a Mac OSX DMG Image in Windows and Converting to Standard ISO Format use dmg2iso
The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard? Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso
I'll only cover theLinux version although the Windows pre-built binary works the same way.
Download dmg2iso here for free (from the author's website)
It's just silly and doesn't make sense that Ubuntu doe........
