You may also get the ports from svn:

  mdconfig -d -u md0
  svn up /usr/src




== Adding IP Alias ==
=== Upgrade FreeBSD ===
=== FreeBSD ===
# mv /usr/src /usr/src.old
Add an alias IP of 10.1.1.2. Alias IPs all have a netmask of 255.255.255.255.
  # svn co svn://svn.freebsd.org/base/release/9.1.0 /usr/src
 
  ifconfig re0 10.1.1.2 netmask 255.255.255.255 alias
 
If you want the changes to be persistent, add the following to <code>/etc/rc.conf</code>
ifconfig_re0_alias0="10.1.1.2 netmask 255.255.255.255 alias"

To build and install 9.1-RELEASE:
=== Linux ===
  # mergemaster -p
route add -net 10.10.2.0/24 dev INSIDE
  # cd /usr/src
echo 1 > /proc/sys/net/ipv4/ip_forward
  # make buildworld
iptables -t nat -A POSTROUTING -o eth2 (outside) -j MASQUERADE
  # make buildkernel
  iptables -A FORWARD -i eth1 -j ACCEPT
  # make installkernel
 
  # reboot
 
  # cd /usr/src
== Upgrading pkgconfig to pkg-config on FreeBSD ==
  # make installworld
  upgrade from pkgconf
  # mergemaster -iU
portmaster -o devel/pkgconf devel/pkg-config
  # reboot
 
== Restarting Services ==
=== Linux ===
Use any one of:
  /etc/init.d/<service> restart
  /etc/init.d/<service> stop && /etc/init.d/<service> start
  service <service> restart
 
=== FreeBSD ===
Usually, the startup scripts are located in <code>/etc/rc.d</code>
  /etc/rc.d/<service> restart
 
However, if it is 3rd party software, they are located in <code>/usr/local/etc/rc.d</code>
  /usr/local/etc/rc.d/<service> restart
 
If you are trying to restart NFS, you may do either:
  /etc/rc.d/nsfd restart
  kill -HUP `cat /var/run/mountd.pid`
 
=== Solaris / SunOS ===
The startup scripts are located in <code>/lib/svc/method/<service></code>
/lib/svc/method/<service> restart
svcadm restart <service>
 
Example: To restart ssh, do any one of:
svcadm restart ssh
svcadm restart svc:/network/ssh
/lib/svc/method/sshd restart

Upgrade FreeBSD

# mv /usr/src /usr/src.old
# svn co svn://svn.freebsd.org/base/release/9.1.0 /usr/src

To build and install 9.1-RELEASE: 

# mergemaster -p
# cd /usr/src
