+====== BSD OS Systems ======
+====== FreeBSD ======
+**FreeBSD** is a freely available and open source implementation of the Berkeley version of the UNIX operating system.This system is in the same family of operating systems as Solaris, AIX, HP-UX, and Digital UNIX. The original UNIX operating system can trace its roots back to the 1960s. The designers of UNIX created a design so flexible and powerful that even 30 years later, UNIX (and thus FreeBSD as well) remains one of the most versatile, well-respected operating systems available. It runs on the following platforms: **AMD64, ARM, ARM64, I386, MIPS, PC98, PPC, SPARC, XBOX, RPI, PICO**. FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.

+The first step after installation system is good download security patches for the operating system
+and download new files for operating system and install.
+<code>
+freebsd-update fetch install
+shutdown -r now
+</code>
+Next step is to update ports collection for the operating system.
+for updating information for FreeBSD ports developers is /usr/ports/CHANGES
+<code>
+portsnap auto
+or
+portsnap fetch
+portsnap extract
+</code>
+Update ports is east command
+<code>
+portsnap fetch update
+</code>
+Security audit for package and FreeBSD
+<code>
+pkg audit -F
+</code>
+====== Apply security patches FreeBSD update, upgrade ======
+==== Apply security patches ====
+<code>
+freebsd-update fetch
+freebsd-update install
+</code>
+==== Upgrade FreeBSD ====
+<code>
+freebsd-update fetch
+freebsd-update upgrade -r 11.0-RELEASE or other version

+FreeBSD has several desktop environments - Xfce4, Mate, Gnome3, Cinnamon, KDE, Lumina
+==== How install Mate desktop ====
+<code>
+pkg install mate-desktop mate xorg slim
+</code>
+Enable components for kernel in etc/rc.conf
+You need enable this component:
+<code>
+zfs_enable="YES"  - if you use ZFS file system
+hald_enable="YES"
+dbus_enable="YES"
+slim_enable="YES"
+</code>
+if you want to enable crash dump, if don't you write "NO"
+<code>
+dumpdev="AUTO"
+</code>
+Next step is create file .xinitrc in /root/ and /home/user/ with command
+<code>
+exec mate-session
+</code>
+  and reboot.
+==== How install Xfce desktop ====
+<code>
+pkg install xfce4-desktop xfce xorg slim
+</code>

+zfs_enable="YES"  - if you use ZFS file system
+hald_enable="YES"
+dbus_enable="YES"
+slim_enable="YES"
+</code>
+if you want to enable crash dump, if don't you write "NO"
+<code>
+dumpdev="AUTO"
+</code>
+Next step is create file .xinitrc in /root/ and /home/user/ with command
+<code>
+exec startxfce4
+</code>
+  and reboot.
+==== How to set slim theme ====
+<code>
+# pkg install slim-themes
+# cd /usr/local/share/slim/themes
+# fetch http://daemon-notes.com/downloads/assets/themes/slim-freebsd.tar.bz2
+# tar jxvf slim-freebsd.tar.bz2
+# rm slim-freebsd.tar.bz2
+Edit and set /usr/local/etc/slim.conf
+#current_theme       default
+current_theme       freebsd
+</code>
+==== Optimus on Freebsd ====
+Comment out Nvidia-related parts from your [[ https://www.freebsd.org/cgi/man.cgi?xorg.conf | xorg.conf ]]:
+<code>

+<code>
+kld_list='i915kms'
+</code>
+==== NTPD ====
+==== NTPD synchronize ====
+<code>
+ntpdate_enable="YES"
+ntpdate_hosts="in.pool.ntp.org"
+</code>
+Or manually update time and date
+<WRAP center round important 60%>
+securelevel on 2 then you cannot set time only about second.
+</WRAP>
+<code>
+ntpdate -b pool.ntp.org
+sudo service ntpd start
+</code>
+==== Disable Beep ====
+<code>
+# sysctl hw.syscons.bell=0
+# reboot
+</code>
+or if you use XFCE
+<code>
+set bell-style none
+</code>
+==== Enable sudo ====
+You must edit sudoers file
+<code>
+visudo
+</code>
+==== Change standard shell to fish ====
+You must add line in /etc/shells for example fish shell
+<code>
+/usr/local/bin/fish
+</code>
+Change shell and path your favorite shell
+<code>
+chsh -s /usr/local/bin/fish
+</code>
+=== Aliases ===
+[[http://bin63.com/cool-bash-aliases-for-freebsd | Cool aliases ]]
+=== Paths for shell ===
+If you need PATH for example compiler or some options
+<code>
+# ASAN settings
+set -x ASAN_SYMBOLIZER_PATH /usr/local/llvm50/bin/llvm-symbolizer
+set -x ASAN_OPTIONS verbosity=1
+set -x ASAN_OPTIONS symbolize=1
+set -x ASAN_OPTIONS detect_stack_use_after_scope=1
+# UBSAN settings

+</code>
+==== Mount Devices ====
+==== Mount msdosfs ====
+<code>
+# ls /dev/da*
+# mount_msdosfs /dev/da0 /media/usb
+</code>
+==== Mount ext2/ext3/ext4 ====
+Fuse-ext2 mounts an ext2/ext3/ext4 partition or image file
+For control kernels fuse modules is command:
+<code>
+kldstat
+</code>
+If you don't have fuse.ko module in the kernel
+you use this command
+<code>
+kldload fuse
+</code>
+Then mount your partition
+<code>
+fuse-ext2  /dev/your_partition /media/
+</code>
+==== Mount NTFS ====
+For mounting ntfs file system you must kernel module loaded.
+For control kernels fuse modules is command:
+<code>
+kldstat
+</code>
+and load FUSE kernel module:
+<code>
+kldload fuse
+</code>
+and then you can mount ntfs filesystem.
+<code>
+# ls /dev/da*
+# ntfs-3g  /dev/your_partition  /mnt/
+</code>
+==== Automounting Removable Media ====
+Uncomment in config file in /etc/auto_master
+<code>
+/media		-media		-nosuid
+</code>
+Add lines to /etc/devd.conf
+<code>
+notify 100 {
+	match "system" "GEOM";
+	match "subsystem" "DEV";
+	action "/usr/sbin/automount -c";
+};
+</code>
+Reload service

+service automount reload
+service devd restart
+</code>
+and added configuration /etc/rc.conf
+<code>
+autofs_enable="YES"
+</code>
+======  Portmaster ======
+<code>
+portmaster -L - Check all update for ports
+portmaster -a - Upgrade ports
+portmaster -af - Rebuild of installed application
+</code>
+======  Debug ports ======
+Just put the following in /etc/make.conf and then recompile the ports
+you want to include debug symbols:
+<code>
+WITH_DEBUG=	yes
+</code>
+more information
+<code>
+/usr/ports/Mk/bsd.port.mk
+</code>
+====== Compiling programs ======
+==== Python3, Py3-QT5 ====
+First thing is to add version python to /etc/make.conf .If you haven't this file you must create.
+This conf file is for every compilation in system.
+<code>
+DEFAULT_VERSIONS+= python=3.5 python3=3.5
+</code>
+Next step is compile with default version python3.5
+<code>
+sudo portmaster python3
+</code>
+===== How to setup MYSQL Database =====
+The first step is the installation
+<code>
+sudo pkg install mysql56-server
+</code>
+next step is enable in /etc/rc.conf
+<code>
+sudo sysrc mysql_enable=yes
+</code>
+Remember to run mysql_upgrade the first time you start the MySQL server after an upgrade from an earlier version.
+Now start MYSQL Server
+<code>
+sudo service mysql-server start
+</code>
+then set database
+<code>
+sudo mysql_secure_installation
+</code>

+====== Troubleshooting with FreeBSD ======
+===== SSH =====
+==== Too many authentication failures ====
+If You are not able to authenticate via ssh and message "Too many authentication failures" is logged in /var/log/auth.log you probably have more than 2 keys loaded in your ssh agent that are failing to authenticate. To solve this unload keys you are not using from ssh agent (ssh-add -d path/ ssh-add -D), use ssh -i path_to_key or create an appropriate section in your ~/.ssh/config with IdentityFile.
+===== BOOT on FreeBSD =====
+ ==== Fatal double fault FreeBSD 10.3 - i386 , FreeBSD 11 - i386  ====
+{{:project:freebsd:img_20170101_174458_hdr.jpg?600|}}
+The fatal double fault is a problem on FreeBSD - i386 with ZFS file system.
+As described in /usr/src/UPDATING entry 20121223, rebuilding the kernel with options KSTACK_PAGES=4 has been observed to resolve the boot-time crash.
+This, however, is not an ideal solution for inclusion in the GENERIC kernel configuration, as increasing KSTACK_PAGES
+implicitly decreases available usermode threads in an environment that is already resource-starved.
+You must do this steps for new kernel:
+<code>
+# mkdir -p /usr/src
+# svnlite co svn://svn.freebsd.org/base/releng/10.2 /usr/src
+# make -C /usr/src kernel-toolchain
+# printf "include GENERIC\noptions KSTACK_PAGES=4\n" > /usr/src/sys/i386/conf/ZFS
+# make -C /usr/src buildkernel KERNCONF=ZFS
+# make -C /usr/src installkernel KERNCONF=ZFS
+</code>

+For FreeBSD 11.0 - More information on page https://www.freebsd.org/releases/11.0R/errata.html
+==== How to boot from live CD ====
+If you have a problem with boot on FreeBSD and cannot run the system.
+{{:project:freebsd:img_20170101_174458_hdr.jpg?600|}}
+Back to FreeBSD menu and choose option 3. ( Escape to loader prompt )
+For help in command line is command help or ? (list of commands )
+help set are options for the command set
+{{:project:freebsd:img_20170102_192147_hdr.jpg?600|}}
+For boot from CD is commnad
+<code>
+set boot_cdrom (for mount filesystem)
+boot
+</code>
+{{:project:freebsd:img_20170105_201210_hdr.jpg?600|}}
+Look for a mounted filesystem with command mount.If you haven't zfs filesystem mounted you must run command and connect zpool :
+<code>
+zpool import -f zroot
+</code>
