Bootchart is a software for performance analysis and visualization of the GNU/Linux boot process. Resource utilization and process information are collected during the boot process and can later be displayed in a PNG, SVG or EPS-encoded chart.

The boot process is modified to start the boot logger (/sbin/bootchartd) instead of /sbin/init. The boot logger will run in background and collect information from the proc file system (/proc/[PID]/stat, /proc/stat and /proc/diskstats).

The statistics are logged to a virtual memory file system (tmpfs). Once the boot process completes (denoted by the existence of specific processes), the log files are packaged to /var/log/bootchart.tgz.

The log package can later be processed using a Java application which builds the process tree and renders a performance chart. The chart may then be analyzed to examine process dependency and overall resource utilization. A renderer web form is also available on the project web site.

The chart can then be analyzed to examine process dependency and overall resource utilization.

Runing:

1. Install bootchartd and the bootchart renderer. See INSTALL for details.

2. Modify your boot loader (GRUB/LILO) if necessary. Alternatively, change the kernel command line interactively upon reboot.
Reboot.

3. Verify that /var/log/bootchart.tgz was created and contains the log files.

4. Render the chart by running:

$ java -jar bootchart.jar

Alternatively (if no Java Development Kit is installed to build the JAR package), the web renderer may be used.

To use the web renderer from a script, run:
curl --form format=svg --form log=@/var/log/bootchart.tgz
http://bootchart.klika.si:8080/bootchart/render > bootchart.svgz

(optionally replacing the svg/bootchart.svgz pair with png/bootchart.png or eps/bootchart.eps.gz)

5. View the generated image and analyze the chart.
SVG images may be viewed using any of the following programs:
- rsvg-view (librsvg; GNOME)
- svgdisplay (ksvg; KDE)
- Gimp (using the gimp-svg plugin)
- Inkscape
- Squiggle (Batik; http://xml.apache.org/batik/)

To get help for additional options, run:

$ java -jar bootchart -h

How it works:

Logger Startup

The boot logger (/sbin/bootchartd) is run by the kernel instead of /sbin/init. This can be achieved by modifying the GRUB or LILO kernel command line, e.g.:

/boot/grub/menu.lst
[...]
title Fedora Core (2.6.10) - bootchart
root (hd0,1)
kernel /vmlinuz-2.6.10 ro root=/dev/hda1 init=/sbin/bootchartd
initrd /initrd-2.6.10.img

The installation script and RPM package will try to add the boot loader entry automatically.

The boot logger will start itself in the background and immediately run the default init process, /sbin/init. The boot process will then continue as usual.

Data Collection

Since the root partition is mounted read-only during boot, the logger needs to store data in memory, using a virtual memory file system (tmpfs).

As soon as the /proc file system is mounted — usually early in the sysinit script — the logger will start collecting output from various files:
/proc/stat system-wide CPU statistics: user, system, IO and idle times
/proc/diskstats system-wide disk statistics: disk utilization and throughput
(only available in 2.6 kernels)
/proc/[PID]/stat information about the running processes: start time, parent PID, process state, CPU usage, etc.

The contents of these files are periodically appended to corresponding log files, every 0.2 seconds by default.

The logger will try to detect the end of the boot process by looking for specific processes. For example, when in runlevel 5 (multi-user graphical mode), it will look for gdmgreeter, kdm_greet, etc. As soon as one of these processes is found running, the logger will stop collecting data, package the log files and store them to /var/log/bootchart.tgz.

Optional Process Accounting

In most cases, the output from /proc/[PID]/stat files suffices to recreate the process tree. It is possible however, that a short-lived process will not get picked up by the logger. If that process also forks new processes, the logger will lack dependency information for these "orphaned" processes — meaning that they might get incorrectly grouped by the chart renderer.

When truly accurate dependency information is required, process accounting may be utilized. If configured, the kernel will keep a log file with detailed information about processes. BSD process accounting v3 includes information about the process PID and parent PID (PPID) — effectively enabling an accurate reconstruction of the process tree.

To enable process accounting, the kernel needs to be configured to include CONFIG_BSD_PROCESS_ACCT_V3, under:

[ ] General setup
[ ] BSD Process Accounting
[ ] BSD Process Accounting version 3 file format

The GNU accounting utilities (package psacct or acct) also need to be installed. The boot logger will use the accton command to enable process accounting; it will include the accounting log in the tarball.

Visualization

The log tarball is later passed to the Java application for parsing and rendering the data. The CPU and disk statistics are used to render stacked area and line charts. The process information is used to create a Gantt chart showing process dependency, states and CPU usage.

A typical boot sequence consists of several hundred processes. Since it is difficult to visualize such amount of data in a comprehensible way, tree pruning is utilized. Idle background processes and short-lived processes are removed. Similar processes running in parallel are also merged together.

Finally, the performance and dependency charts are renderer as a single image in either PNG, SVG or EPS format.

FCCU GNU/Linux Forensic Bootable CD is a bootable CD based on KNOPPIX that contains a lot of tools suitable for computer forensic investigatins, including bash scripts.
FCCU GNU/Linux Forensic Boot CDs main purpose is to create images of devices prior to analysis, and it is used by the Belgian Federal Computer Crime Unit.
Main features:
- This CD is based on KNOPPIX by Klauss Knopper.
- It is a remaster that I made to use at my work as a computer forensic investigator.
- Its main purpose is to create images copies of devices before analyse.
- It does not use a lot of cpu cycles for unnecessary programs, that is why it drops you to a shell right after the boot.
- It recognizes lots of hardware (Thanks to Klauss Knopper).
- It leaves the target devices unaltered (It does not use the swap partitions found on the devices).
- It contains a lot of tools with forensic purpose.
Enhancements:
- This release adds a new set of tools that allow an investigator to capture the memory from another host trough the Firewire bus, even if the target host is an MS Windows box.
- A new tool to retrieve images from Thumbs.db (MS win thumbnails cache) was added.
- Rdd, a new forensic image acquisition tool, was added.
- A lot of other tools were added and upgraded.

yoursql project is a mysql version fingerprint tool written in C.

This will only work on hosts that actually let you connect, if you are blocked by an ACL, this wont work.

slakbootIBS (Slackware Interactive Boot Scripts) is an enhanced set of replacement boot scripts for the Slackware Linux distribution.

Slackware Interactive Boot Scripts includes a set of control and dispatch tools for configuring and booting with colorized interactive scripts. The new boot process allows the operator to select or skip start-up components in realtime.

It facilitates debugging of startup problems and allows operators to maintain a common baseline to support several local configurations or multiple servers with a single set of scripts.
