-====== 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.

-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

-==== 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

-======  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

-====== 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

-==== 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>
