 +====== 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.

 +==== Tuning Power Laptops ==== 
 +[[https://​wiki.freebsd.org/​TuningPowerConsumption]]
 +
 +====== First step after installation FreeBSD ======
 +
 +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-update install
 +</​code>​
 +====== Desktop Environments ====== ​
 +
 +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>​
 +
 +Enable components for kernel in etc/rc.conf
 +
 +You need to run desktop
 +
 +<​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>​
 +
 +If you don't have fuse.ko module in the kernel
 +you use this command

 +
 +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.

 +
 +====== ​ Debug ports ====== ​
 +
 +Just put the following in /​etc/​make.conf and then recompile the ports

 +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

 +====== 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 10.3 - More information on page https://​www.freebsd.org/​releases/​10.3R/​errata.html
 +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>​
