State and justify the attributes you'd like to receive upon successful approval and completion of this project.

  • attribute1: why you feel your pursuit of this project will gain you this attribute
  • attribute2: why you feel your pursuit of this project will gain you this attribute
  • etc…

Procedure

The actual steps taken to accomplish the project. Include images, code snippets, command-line excerpts; whatever is useful for intuitively communicating important information for accomplishing the project.

Installation:

  • OpenBSD Installation Guide
  • File Sets: The complete OpenBSD installation is broken up into a number of file sets:
    • bsd: The kernel (required)
    • bsd.mp: The multi-processor kernel (only on some platforms)
    • bsd.rd: The ramdisk kernel; a live OpenBSD environment that runs entirely in memory. This can be used to perform a complete installation, an upgrade to a newer version, or for disaster recovery.
    • baseXX.tgz: The base system (required)
    • compXX.tgz: The compiler collection, headers and libraries
    • manXX.tgz: Manual pages
    • gameXX.tgz: Text-based games
    • xbaseXX.tgz: Base libraries and utilities for X11 (requires xshareXX.tgz)
    • xfontXX.tgz: Fonts used by X11
    • xservXX.tgz: X11's X servers. This set is rarely needed if you don't intend to run X.
    • xshareXX.tgz: X11's man pages, locale settings and includes

Configuration:

Base System:

  • Default shell: ksh
    ksh first reads /home/user/.kshrc then /home/user/.profile. The .profile file is read only once by the login ksh instance, while the .kshrc file is read by each new ksh instance.
  • Initialization files:
    • user: ~/.profile
    • host/all users: /etc/profile
    • hardware/software: /etc/environment
    • shell: ~/.kshrc
      • Example .kshrc:
        EDITOR=vim
EMAIL=user@example.com
HISTFILE=~/.ksh_history
HISTSIZE=10000
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8
\#LC_CTYPE=en_US.UTF-8
PKG_PATH=ftp://openbsd.mirror.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/
ALT_PKG_PATH=http://openbsd.mirror.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)
\# color prompt: [$TIME]{$USER@$HOST}($PWD)$>
RST="\e[00m"; RED="\e[1;91m"; GRN="\e[1;92m"; BLU="\e[1;94m"; MAG="\e[1;95m"; CYN="\e[1;96m"

    PS1="[$BLU\A$RST]$RED{$RST$CYN\u@\h$RST$RED}($RST$MAG\w$RST$RED)\\$>$RST "
else
    PS1="[$BLU\A$RST]$GRN{$RST$CYN\u@\h$RST$GRN}($RST$MAG\w$RST$GRN)\\$>$RST "
fi
unset RST RED GRN BLU MAG CYN
export EDITOR EMAIL HISTFILE HISTSIZE LC_ALL LANG PKG_PATH ALT_PKG_PATH PS1

\# reload .kshrc
alias reload='. ~/.kshrc'
alias cp='cp -i'
alias ls='ls -A --color=auto'
alias ll='ls -aFhl --color=auto'
alias mv='mv -i'
alias rm='rm -i'
      • Enable execution of .kshrc:
        $ echo "export ENV=${HOME}/.kshrc; export ENV" >> .profile

Kernel:

Building the System from Source:

Networking:

Initial Steps: 

## Edit system hostname
$ doas vi /etc/myname
## Configure gateway IP address
$ doas vi /etc/mygate
## Configure the DNS IP address
$ doas vi /etc/resolv.conf

Wired: 

## Configure static IP address and network mask: (em0 used as example)
$ doas vi /etc/hostname.em0

Wireless: 

## Configure static IP address and network mask: (urtw0 used as example)
$ doas vi /etc/hostname.urtw0
## wpa_supplicant instructions
## Installation
$ doas pkg_add -ivvv wpa_supplicant
## Usage: (urtw0 used as example)
# Scan for WiFi APs:
$ doas ifconfig urtw0 up
$ doas ifconfig urtw0 scan
 
# Connect to a WPA Network:
$ ifconfig urtw0 nwid AP-SSID wpakey $uPPP3R_$3CURE_p@$$WoRD
$ dhclient urtw0
 
# Connect to a WPA Network with spaces in the BSSID: (Single quotes)
$ ifconfig urtw0 nwid 'AP-SSID with Spaces' wpakey $uPPP3R_$3CURE_p@$$WoRD
$ dhclient urtw0
 
# Connect to a WPA Network with symbols in the BSSID: (Double quotes)
$ ifconfig urtw0 nwid "AP-SSID_w!th_$ymb01$" wpakey $uPPP3R_$3CURE_p@$$WoRD
$ dhclient urtw0
 
## Monitor Mode:
# Show wireless card information:
$ doas dmesg | grep 'urtw0'
# Show Media Options:
$ ifconfig urtw0 media
# ENABLE Monitor Mode:
$ doas ifconfig urtw0 mediaopt monitor
# DISABLE Monitor Mode:
$ doas ifconfig urtw0 -mediaopt monitor

Packages/Ports/Source:

Packages:

  • Install a package:
    $ doas pkg_add -imVvvvvv package_name | tee package_name.txt
  • Remove a package:
    $ doas pkg_delete -aimVvvvvv <package_name>
  • Update a single package:
    $ doas pkg_add -umVvvvvv <package_name>
  • Update installed packages:
    $ doas pkg_add -umVvvvvv
  • Useful Packages:
    • Package Management:
      • pkg_mgr: A high-level, user-friendly package browser for OpenBSD. It allows the user to install, uninstall, search & browse available packages using a simple curses interface. It relies on sqlports for its internal database, pkg_add(1), pkg_info(1) and pkg_delete(1) for package operations.
    • Terminal Multiplexers: byobu, screen, tmux

Ports:

Upgrading/Updating:

Initial Steps:

  • Add path:
    $ vi .profile
export PKG_PATH=ftp://openbsd.mirror.frontiernet.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/
export ALT_PKG_PATH=http://openbsd.mirror.frontiernet.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/
$ doas vi /root/.profile
export PKG_PATH=ftp://openbsd.mirror.frontiernet.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/
export ALT_PKG_PATH=http://openbsd.mirror.frontiernet.net/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/

Upgrading:

  • -release: The version shipped every six months.
  • -current: The development branch.
  • -stable: The -release branch, plus patches found on the errata page.
    • Using cvs:
      • Fetching the -stable trees:
        $ cd /usr
$ cvs -qd anoncvs@anoncvs.example.org:/cvs checkout -rOPENBSD_6_3 -P src
      • Updating the -stable trees:
        $ cd /usr/src
$ cvs -q up -Pd
        • Specify the branch with the -r command
        • All the trees (src, ports, xenocara, www) should be checked out and updated at the same time.
      • Fetching the -current trees:
        $ cd /usr
$ cvs -qd anoncvs@anoncvs.example.org:/cvs checkout -P src
      • Updating the -current trees:
        $ cd /usr/src
$ cvs -q up -Pd

Updating:

  • Firmware: using fw_update(1):
    $ doas fw_update -v
  • System:
  • Four active source repositories:
    • src - source code for the base system
    • ports - the ports tree
    • www - web pages
    • xenocara - xenocara
  • Preloading the source code tree:
    $ cd /tmp
$ wget http://mirrors.mit.edu/pub/OpenBSD/6.3/src.tar.gz
$ wget http://mirrors.mit.edu/pub/OpenBSD/6.3/sys.tar.gz
$ wget http://mirrors.mit.edu/pub/OpenBSD/6.3/ports.tar.gz
$ wget http://mirrors.mit.edu/pub/OpenBSD/6.3/xenocara.tar.gz
$ cd /usr/src
$ tar xvfz /tmp/sys.tar.gz
$ tar xvfz /tmp/src.tar.gz
$ cd /usr
$ tar xvfz /tmp/ports.tar.gz
$ tar xvfz /tmp/xenocara.tar.gz
$ rm /tmp/*.tar.gz

  • Unmounting the USB drive:
    $ doas umount /mnt/usb

Code

Upon completion of the project, if there is an applicable collection of created code, place a copy of your finished code within <code> </code> blocks here. 

/*
 * hello.c - A sample "Hello, World!" program
 * 
 * written by NAME for COURSE on DATE
 *
 * compile with:
 *   gcc -o hello hello.c
 *
 * execute with:
 *   ./hello
 */
 
#include <stdio.h>
 
int main()
{
    printf("Hello, World!\n");    // Output message to STDOUT
    return(0);
}

Execution

Again, if there is associated code with the project, and you haven't already indicated how to run it, provide a sample run of your code: 

lab46:~/src/cprog$ ./hello
Hello, World!
lab46:~/src/cprog$

Reflection
