10      FreeBSD(stable):  
       o read more about BSD package systems (pkg, cvsup)  
         x for simple package installation/de-installation use pkg  
           x install downloaded package:  
               :# pkg_add <package>-<version>.tgz  
           x install package via remote server(only if package is available as *latest*):  
                 pkg_add -r <package>.tgz  
         x using cvsup  
           x newbies could use cvsupit (not what it really does..)  
               :# pkg_add -r cvsupit.tgz  
             - cvsupit will proberly ask you for the default values it  
               place at /etc/cvsupfile, which is used by cvsup  
             - after that it will start cvsup to update your system  
           x if /etc/cvsupfile already exists and you know what you do,  
              this command will update your system (maybe run it via cron...):  
               :# /usr/local/bin/cvsup -g -L 2 /etc/cvsupfile  
       o whats about daemon start-stop scripts (like at linux: /etc/init.d/) ?  
       x configure and compile custom kernel:  
         x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html  
         x create custom kernel conf-file  
           - cd usr/src/sys/i386/conf/  
           - copy default kenrnel GENERIC to eg MYKERNEL  
           - edit/modify MYKERNEL  
         x configure sources(really?)  
           - run /usr/sbin/config MYKERNEL  
         x build kernel  
           - cd ../../MYKERNEL  
           - make depend  
           - make  
           - make install  
       x use packet fiters (firewall):  
         x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html  
         x some options at the kernel have to be enabled:  
         <pre style="font-size:10px">  
           options IPFIREWALL                       #Compiles into the kernel the code for packet filtering.  
           options IPFIREWALL_VERBOSE    #Enables code to allow logging of packets through syslogd.  
                                                                   # Without this option, even if you specify that packets should be logged in the filter rules,  
                                                                   #  nothing will happen.  
           options IPFIREWALL_VERBOSE_LIMIT=10      #Limits the number of packets logged through syslogd on a per entry basis.  
                                                                                     # You may wish to use this option in hostile environments in which you want to log firewall activity,  
                                                                                     # but do not want to be open to a denial of service attack via syslog flooding.  
                                                                                     # When a chain entry reaches the packet limit specified, logging is turned off for that particular entry.  
                                                                                     # To resume logging, you will need to reset the associated counter using the ipfw(8) utility:  
                                                                                     #        ipfw zero 4500  
                                                                                     #    Where 4500 is the chain entry you wish to continue logging.  
           options IPFIREWALL_DEFAULT_TO_ACCEPT     #This changes the default rule action from ``deny'' to ``allow''.  
                                                                                         # This avoids the possibility of locking yourself out if you happen to boot a kernel with IPFIREWALL support but have not configured your firewall yet.  
                                                                                         # It is also very useful if you often use ipfw(8) as a filter for specific problems as they arise.  
                                                                                         # Use with care though, as this opens up the firewall and changes the way it works.  
          </pre>  
         x firewall is enabled at /etc/rc.conf (or /etc/rc.conf.local)  
              firewall_enabled = "YES"  
              firewall_type = "<firewall_type>"  
           x <firewall_type> is either a case at /etc/rc.firewall (/etc/rc.firewall6 for ipv6)  
              or some custom file to read rules from.  
           x  Use firewall_type = "OPEN" for default policy 'OPEN' (allow all)
