490 Part III . Choosing and Installing a Linux Distribution . Logical Volume Management tools For file systems created with LVM, there are lvm and evms tools. (Logical volume management lets you add space to areas of a file system without changing the physical partitions.) . Security tools Check whether the data on your system has been compromised with tools such as chkrootkit (to check for software installed by hackers to let them access your system), as well as clamav and clamd (to scan for existing and incoming viruses). Use nmap (scan network computers for open ports) and nc (the Netcat utility for checking connections to remote hosts) for checking network security. . Backup tools As you might expect, this distribution contains standard Linux tools for archiving data (tar, cpio, dump, rar, and so on) and compressing data (such as bzip2, gzip, and compress). Likewise, it contains standard tools for copying your data over the network (scp, sftp, ftp, and so on). Because System Rescue CD doesn t include a graphical interface, it can get a lot of commands into about 100MB of disk space. Some of the tools however, such as the midnight commander (mc command) file manager, provide a GUI-like interface from a regular Linux shell via the ncurses libraries. The System Rescue CD image is included on the CD that comes with this book. Refer to Appendix A for information on copying and burning the System Rescue CD image to CD. KNOPPIX Security Tools Distribution The Knoppix-STD goes lightweight on the window manager to go heavyweight on the diagnostic tools. The distribution contains hundreds of tools that can be used for repairing and assessing computer and network security (see http://knoppixstd. org). Instead of a full GNOME desktop, Knoppix-STD uses the Fluxbox window manager. It will run on lesser machines, but you ll get a usable GUI on almost any Pentium-class machine with at least 64MB of RAM. With at least 640MB of RAM, you can run the entire distribution from RAM (type knoppix toram to boot it to run entirely from RAM). With Knoppix-STD running in RAM, the system operates faster and your CD or DVD drive is available for other purposes. Go to the project s Tools page (www.knoppix-std.org/tools.html) to find out about more features in the project. Or go to the download page (www.knoppixstd. org/download.html) to download and try it yourself. The Inside Security Rescue Toolkit INSERT (Inside Security Rescue Toolkit) is another KNOPPIX derivative that includes features from Damn Small Linux as well. INSERT bills itself as a disaster recovery and network analysis system. It contains a more compact set of tools to fit On the CD-ROM
