• Cloned VM/Server/Computer in Linux won't boot and goes to initramfs busybox Solution


    This is mainly for if you've done something silly like trying to clone a Live, running VM image. In this example, the VM initially finds grub and tries to boot but is kicked straight into initramfs rescue mode/busybox right after this. If you've done this "silly" thing, you could have dataloss but a lot of times just using fsck will fix it as you are guaranteed at best to have some corruption and inconsistencies in the filesystem. My theory is that some files wer........

  • 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?
