Earlier this evening I needed to install a newer version of libpcap on a CentOS Linux server. The current version available via the yum package manager is libpcap version 0.9.4-15 and I needed something newer than libpcap version 0.9.7. I ended up not being able to find a yum repository or RPM package that included a version newer than 0.9.4-15 so I decided to upgrade to the latest stable version of libpcap currently available which is libpcap version 1.1.1. Below are directions on downloading libpcap, installing it, and then verifying it is installed.
The rar command can be useful on Linux to not only compress a file but also split the file into multiple parts during the compression. This will make the files easier to transfer to other servers or easier for other people to download. First rar needs to be installed which can done on CentOS using the directions below. After that we describe how to easily compress and break a file into multiple chunks using one simple rar command.
Earlier I was working on a clients Mac OSX laptop and needed to login remotely without the hassle of setting a password and then removing it when I was done. The article below will describe not only how to enable SSH from a terminal window on the Macintosh laptop itself but also how to configure SSH so it will allow remote login via SSH without a password.
While messing around with a client’s laptop this afternoon I needed to enable SSH and decided to not only do it via the CLI but locate the method to do it via the Mac OSX Desktop as well. Enabling SSH via the OSX GUI can be done via the Sharing sub section of System Preferences by checking one box. Below is information on how to launch OSX System Preferences, navigate to enabling services in Sharing, and then enabling SSH.
Dmitry or Deepmagic Information Gathering Tool is an all in one host information tool included in Backtrack 4’s Information Gathering section. Personally I prefer doing most info gathering using tools built into Linux however it is nice to run a tool like this in the background and come back later if you are multi-tasking. Before getting into the details of Dmitry please see this article relating to a Segmentation Fault that can occur with Dmitry on Backtrack 4.
