As many people who follow this site may know I recently switched from Linux to Windows 7 as my daily operating system. This morning I saved a file as the default “save” in word instead of “save as” which is what I normally do. I then looked in my users My Documents directory and the file wasn’t there. At this point I was perplexed and a little annoyed so I ran a search for the file and found it in C:/Users/Public/My Documents which is not where I wanted it to go. I am not sure whether this was user error and I just somehow set up my system wrong or if this is the default Windows 7 behavior. Either way I decided to out line how I straightened it out.
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. Below I describe how to generate a GPG key to be used to sign RPM packages created using the rpmbuild command. First below is a message that will be received when attempting to install unsigned packages using yum with the default yum configuration.
Not enough random bytes available. Please do some other work to give the OS a chance to collect more entropy! (Need 283 more bytes)
When working to create a GPG key to sign some RPM packages I was building I ran into a message I had never seen before. I was building the RPM packages on an older server with not a lot of power which I am assuming contributed to my issue. The error is noted below but basically means you need to generate a lot of random bytes which are used to create a unique key. Within the error it states that the computer needs to collect more entropy so below I explain the error in more detail, what entropy means, why more entropy is needed, and how to generate as much as possible in a short amount of time to finish generating the GPG key.
Today I was working on a Vista laptop and I encountered the error “page failed to load” while trying to open many of the control panel icons. I thought at first maybe the permissions for the user were screwed up even though the user was an administrator. So next I enabled the administrator account and booted into that only to find that the issue was still there. The problem was specifically happening when I tried to select user accounts. In my searching I found may so called “solutions” but none of them survived a reboot. Below I show how I repaired the file system to fix this error.
It seems like, recently, there have been a whole lot of Internet Explorer vulnerabilities in the wild and even more virus’s running rampant on the internet. After having removed quite a few this week I decided to do a short write up on a tool I use quite often when working with, and trying too analyze malware. The tool is called Sandboxie.
