FreeBSD wifi ap

Antud õpetus räägib kuidas enda wifi kaarti sisaldab FreeBSD ruuter muuta wifi ruuteriks ehk access point'iks

Muudame r.conf'i /etc kataloomas Enne peame kindlaks tegema enda wifi kaardi nime. Antud näites on see wi0

pccard_enable="YES" # Set to YES if you want to configure PCCARD devices.
pccard_ifconfig="inet 10.0.0.2 netmask 255.255.255.0"

Need read on vajalikud ainult siis kui kasutate pcmci kaarti üle ISA silla nagu mina

ipnat_enable="YES"
ipnat_rules="/etc/ipnat.conf"

dhcpd_enable="YES"
dhcpd_flags="-q"                              # command option(s)
dhcpd_conf="/usr/local/etc/dhcpd.conf"      # configuration file
dhcpd_ifaces="wi0"                             # ethernet interface(s)

/etc/ipnat.conf'i nat'i tegemine. Võrgukaart millest tuleb internet masinasse on ed0

#nati pordid
map ed0 192.168.0.0/24 -> 0.0.0.0/32 portmap tcp/udp 40000:65000
map ed0 192.168.0.0/24 -> 0.0.0.0/32

installime isc-dhcpd3-server ja teeme talle konfiguratsiooni /usr/local/etc/dhcpd.conf

default-lease-time 21600;
max-lease-time 7200;
ddns-update-style none;
log-facility local7;
ignore client-updates;

subnet 192.168.3.0 netmask 255.255.255.0 {
  range 192.168.3.5 192.168.3.200;
  option subnet-mask 255.255.255.0;
  option broadcast-address 192.168.3.255;
  option routers 192.168.3.1;
  option domain-name-servers 194.126.115.18, 194.126.101.34;
}

# This script was created off suggestions found in:

# For more information on the controls used in this script, PLEASE
# 'man wicontrol' - it is chock full of important settings/info.
# Remember also that 'wicontrol' is used for wi based PC Cards. If
# for example, you are using an Aeronet card, your actual command
# will be 'ancontrol'. Again, make sure to man xxxcontrol for the 
# proper documentation.  

# Set the channel of the wireless network to 5
wicontrol -f 5 

# Set the wifi adapter to infrastructure mode - i.e. we do not
# want the network set in ad hoc mode.
wicontrol -p 1

# Set the extension of BSS to IBSS. Currently, the switch -c that 
# changes that setting doesn't completely work for wicontrol but 
# should in the future. Refer to 'man wicontrol' for more information.
wicontrol -c 1

# name the server and AP (this is primarily used for diagnostic 
# controls see 'man wicontrol').
wicontrol -s "myap"

# Seadistame wep võtme (muuda endale sobivaks)
wicontrol -k "12345"

# Lubame WEP'i
wicontrol -e 1

# Muudame SSID nime enda wifiruuteril
ifconfig wi0 ssid "myap"

# Anname wifi kaardile ip. See hakkab olema nüüd gw ip edaspidi kõigile klientidele
ifconfig wi0 inet 192.168.3.1 netmask 255.255.255.0
