SNMP can be a hidden gem that seems to be overlooked sometimes during penetration testing. It is really cool the information you can obtain just using snmpwalk from the command line however the information can be lengthy and unless you are an SNMP OID library or feel like googling a bunch of different stuff it really helps to have tools such as snmpcheck available.

I have been playing around with building RPM packages today on CentOS because I needed to upgrade curl and the latest version available on CentOS didn’t have the features I needed to use. One of the things that had come h up during the RPM build process and the RPM package installation process using yum was the fact that your RPM packages should be signed. Signing RPM packages gives them some validity and will allow others to install them without having to modify their yum.conf file.

I configured a WordPress plugin on my personal blog site to allow me to embed YouTube videos of my kids to share with the family. The plugin is called Youtube With Fancy Zoom and provides a great way to setup a gallery of YouTube thumbnails that when clicked on will open a YouTube movie in a overlay window. Anyway during configuring the plugin, videos, etc. I was logged in to YouTube and assumed everything was working properly. I emailed the new page to my wife to check out and she let me know that she was not able to view the videos because they were all labeled private. The message stating the YouTube videos were private along with how to share the videos with everyone are both detailed below.
