======UNIX Project 2: OpenBSD Installation and Configuration:======


=====Objectives=====


=====Prerequisites=====


=====Background=====


=====Scope=====


=====Attributes=====
  * **Create a //ppp// directory**: //ppp// stands for //Patches//, //Ports//, and //Packages//. Whenever a patch, port, or package is installed, I find it useful to pipe the output to **tee** and place it in this directory. If something went wrong when installing a package, I can check the text file for any warnings or errors. Also, If I am not sure if a particular patch is installed, I can just look in this directory.

=====Procedure=====
After installation, there are some things that need to be configured before it can be used. Items prefixed with a **$** can be executed as the **user** and items prefixed with a **#** must be executed as **root**. Some configuration options must be done for **both** the normal user and the root user:
  * **Update the firmware**:
    * # fw_update | tee ~/ppp/fw_update.txt
  * **A more informative shell prompt**:
    * $ vi ~/.profile
    * export PS1='[$PWD]: $'
    * Save and exit.
  * **Enable the mouse in the terminal**:
    * $ vi /etc/rc.conf
    * $ wsmoused_flags=YES
    * # vi /etc/rc.conf
    * # wsmoused_flags=YES
    * # reboot
  * **Configure Networking**:
    * **IP addresses and network mask**:
      * # vi /etc/hostname.em##
    * **Gateway IP address**:
      * # vi /etc/mygate
    * **DNS IP address**:
      * # vi /etc/resolv.conf
    * **Edit the hostname**:
      * # vi /etc/myname
  * **Install and configure wireless**:
    * # CHANGE TO DOAS
    * # pkg_add -ivvv wpa_supplicant | tee /home/user/ppp/wpa_supplicant.txt
      * **Scan for WiFi networks**:
        * # ifconfig <device> up
        * # ifconfig <device> scan
      * **Connect to a //WPA// WiFi Network**:
        * # ifconfig <device> nwid <SSID> wpakey <PASS>
        * # dhclient <device>
      * **Connect to a //WPA// WiFi Network with __spaces__ in the //BSSID//**:
        * # ifconfig <device> nwid '<SSID_with_spaces>' wpakey <PASS>
        * # dhclient <device>
      * **Connect to a //WPA// WiFi Network with __symbols__ in the //BSSID//**:
        * # ifconfig <device> nwid "<SSID_with_$ymbol$>" wpakey <PASS>
        * # dhclient <device>
      * **Monitor Mode**: **Note:** Hardware must support //Monitor Mode//.
        * # dmesg | grep "<device>"
        * # ifconfig <device> media
        * # ifconfig <device> mediaopt monitor         To enable.
        * # ifconfig <device> -mediaopt monitor        To disable.
  * **Correct the System Time**:
    * **This is optional**. Sometimes this step is need to correct the system time:
      * # ln -fs /usr/share/zoneinfo/America/New_York /etc/localtime
  * **Add Upgrade and Update paths**:
    * $ vi ~/.profile
    * $ export PKG_PATH=ftp://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -m)
    * $ export ALT_PKG_PATH=http://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -m)
    * Save and exit.
    * # vi ~/.profile
    * # export PKG_PATH=ftp://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -m)
    * # export ALT_PKG_PATH=http://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -m)
    * Save and exit.
    * # reboot
===== Additional Steps =====
==== Install and set bash as the login shell: ====
  * # CHANGE TO DOAS
  * # pkg_add -ivvv bash | tee /home/user/ppp/bash.txt
  * # chsh -s /usr/local/bin/bash         (for the //root// user.)
  * # chsh -s /usr/local/bin/bash user    (for the //user// user.)
  * # exit

==== Patching: ====
  * # cd /tmp
  * # wget .../src.tar.gz
  * # wget .../sys.tar.gz
  * # cd /usr/src
  * # tar xvfz /tmp/src.tar.gz
  * # tar xvfz /tmp/sys.tar.gz
  * # cd /tmp
  * # rm src.tar.gz && sys.tar.gz
  * # wget .../*.patch.sig
  * # signify -Vep /etc/signify/openbsd-##-*.pub -x ###.patch.sig \<enter>
  * > -m - | (cd /usr/src && patch -p0)
  * **To recompile the patched software:**
    * # cd <dir>
    * # make obj
    * # make depend
    * # make
    * # make install
  * **To recompile a patched kernel:**
    * # cd /usr/src/sys/arch/`machine`/conf
    * # KK=`sysctl -n kern.osversion | cut -d# -f1`
    * # config $KK
    * # cd ../compile/$KK
    * # make
    * # make install

==== Installing Packages: ====
  * # CHANGE TO DOAS
  * # pkg_add -ivvv <package_name> | tee package_name.txt

==== List installed Packages: ====
  * # pkg_info
  * # pkg_info | grep "package_name"

==== Update installed Packages: ====
  * # pkg_add
  * # pkg_add -u
  * # pkg_add -u <package_name>

==== Useful Packages: ====
  * **clamav**
  * **dnscrypt-proxy**
  * **gnupg**
