You may also get the ports from svn:
svn co svn://svn.freebsd.org/base/releng/9.1 /usr/src
svn up /usr/src


== Adding IP Alias ==
=== FreeBSD ===
Add an alias IP of 10.1.1.2. Alias IPs all have a netmask of 255.255.255.255.


  ifconfig re0 10.1.1.2 netmask 255.255.255.255 alias
=== Upgrade FreeBSD ===
  # mv /usr/src /usr/src.old
# svn co svn://svn.freebsd.org/base/release/9.1.0 /usr/src


If you want the changes to be persistent, add the following to <code>/etc/rc.conf</code>
To build and install 9.1-RELEASE:
  ifconfig_re0_alias0="10.1.1.2 netmask 255.255.255.255 alias"
# mergemaster -p
# cd /usr/src
# make buildworld
# make buildkernel
# make installkernel
# reboot
# cd /usr/src
# make installworld
# mergemaster -iU
  # reboot


== Set a Gateway (Traffic Forwarder) ==
== User Management ==
=== Linux ===
route add -net 10.10.2.0/24 dev INSIDE
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth2 (outside) -j MASQUERADE
iptables -A FORWARD -i eth1 -j ACCEPT


=== FreeBSD ===


== Upgrading pkgconfig to pkg-config on FreeBSD ==
Create a new user with a home directory /home/username:
upgrade from pkgconf
portmaster -o devel/pkgconf devel/pkg-config
 
== 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>
pw useradd -n username -s /bin/sh -m
  /usr/local/etc/rc.d/<service> restart
   


If you are trying to restart NFS, you may do either:
Remove a user and their home directory:
/etc/rc.d/nsfd restart
kill -HUP `cat /var/run/mountd.pid`


=== Solaris / SunOS ===
  pw userdel -n username -r
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


Create a new group


== wget to console ==
pw groupadd groupname


Use the <code>-O -</code> option to output contents to the console.
Show group


  wget -O - http://google.ca
  pw groupshow groupname


== sed ==
Set user to group
=== Simple search / replace ===


  sed 's/<search>/<replace>/g'
  pw groupmod groupname -M username,user2,user3


=== remove HTML tags ===
Add user to group
pw groupmod groupname -m user4


sed -e 's/<[^>]*>//g' <file>
