FreeBSD Tweaks

Maybe useful to some…

• avahi & multicast dns

  pkg install -y avahi-app nss_mdns

• enable avahi daemon in rc.conf:

  avahi_daemon_enable="YES"

• modify the hosts: line in nsswitch.conf:

  hosts: files dns mdns

• by default root shell is csh and user is sh - edit .shrc to get prettier prompt

    PS1="`whoami`@\H:\w\$ "

• (IF using slim) to enable x environment after slim login, create ~/.xinitrc for each user:

    exec /usr/local/bin/mate-session

1. 'git log' output does not show colorized output
   • can see the escape sequence
   • so, as user, type

     git config --global core.pager "ls -r"

Note DHCP client is dhclient - simply run dhclient <interface> when booting to console and using something like USB tethering.

Configure (wireless) network interface (in case was not done during installation)

• FreeBSD has network interface name - based on the driver name (e.g. sis, re)
  • to find this, use pciconf -lv
• for normal wired connection (e.g. re0), add to 'rc.conf'

  ifconfig_re0="DHCP"

• for a wireless connection (e.g. ath0), add in

  wlan_ath0="wlan0"
  ifconfig_wlan0="DHCP"

• for a secured wireless connection (e.g. WPA protected), add in

  wlan_ath0="wlan0"
    ifconfig_wlan0="WPA SYNCDHCP"

  also, append '/ etc/wpa_supplicant.conf'

    network={
        ssid="the_ssid"
        psk="the_psk"
    }

• not sure why but wlan0 was not auto-created?
  • from official handbook, do ifconfig wlan0 create wlandev ath0
  • to start up and scan, do ifconfig wlan0 up scan
  • or just scan, do ifconfig wlan0 list scan

Driver for ASUS E5450 Graphics Card (based on Radeon 5450?)

• install driver

  pkg install -y xf86-video-ati

• to load on startup, edit rc.conf:

  kld_list="radeonkms"

For Intel Graphics (Asus H81M-K Motherboard)

• install driver

  pkg install -y xf86-video-intel

• to load on startup, edit rc.conf:

  kld_list="i915kms"

• install something? (for kernel?)

  pkg install -y drm-kmod

  • some older ones require drm-fake-kmod instead

Web Server (Apache)

• find apache package(s)

  pkg search apache2 | grep -e "^apache2"

• install apache package(s)

  pkg install -y php56 mod_php56 php56-mbstring php56-mcrypt php56-zlib php56-curl php56-gd php56-json

• to load on startup, edit rc.conf:

  apache24_enable="YES"

• default document path is /usr/local/www/apache24/data/

Server Script (PHP)

• find php package(s)

  pkg search php5 | grep -e "^php5"

• install php package(s)

  pkg install -y apache24

• configure /usr/local/ etc/apache24/Includes/php.conf:

    <IfModule dir_module>
      DirectoryIndex index.php index.html
      <FilesMatch "\.php$">
        SetHandler application/x-httpd-php
      </FilesMatch>
      <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
      </FilesMatch>
    </IfModule>

• copy template configuration file # cp /usr/local/ etc/php .ini-production /usr/local/ etc/php .ini

Data-base (mysql/mariadb)

• install package(s)

  pkg install mariadb103-server mariadb103-client php56-mysqli

• to load on startup, edit rc.conf:

  mysql_enable="YES"

• by default, it listens to remote request at port 3306. to check:

  # lsof -i4 -i6
  # sockstat -4 -6

• to allow local access only, edit rc.conf:

  mysql_args="--bind-address=127.0.0.1"

• now, to make sure all is okay:

  # lsof -i4 -i6 | grep mysql
  # netstat -an | grep 3306
  # sockstat -4 -6 | grep 3306

This is nice to have in / etc/ fstab when device assignment may change (e.g. usb drive on different machine may be assigned differently)

For ufs,

# tunefs -L <label> /dev/da0p?

To check if assigned,

# ls /dev/ufs

For swap,

# glabel label <label> /dev/da0p?

To check if assigned,

# ls /dev/label

Then, / etc/ fstab entry can be like,

/dev/label/<label>	none	swap	sw	0	0
/dev/ufs/<label>	/		ufs		rw	1	1

Show partition

# gpart show

Resize partition

# gpart resize -i 3 da0

Not really gpart stuff, but don't forget to grow FS to fit new size

# growfs /dev/da0p3

At the moment, full R/W access for Ext2, Journal-less for Ext3 and R/O for Ext4.

# kldload ext2fs
# mount -t ext2fs /dev/<slice> <mount-path>
