wireless hotspot

This was available in f18 and I had started my testing but as I wiped both systems to run
f19 that is what I actually tested. Both computers had working wired network
connections and alfa usb wireless cards.

Computer that will be the hotspot.
I installed hostapd with yum and then edit /etc/sysconfig/hostapd last line insert -dd between the double quotes
for verbose messages.


Click the network icon on the top bar, scroll to the bottom and select network settings.

Select the wireless interface from the left hand side, if the card is capable you
should see a hotspot button. If your curious open the system log
select messages to see what activating the hotspot does.

Once the hotspot button is selected the Network Settings for the wifi interface
will change to show Network Name (ssid), Security type WEP and a
WEP key which in my case was 10 alphanumeric chars.


From the computer that wants to connect to the hotspot. Open network settings
and look for the hotspot ssid. Oddly it showed a very poor signal strength which
I ignored and connected.


ipv4 addr on the hotspot 10.42.0.1
ipv4 addr on the remote 10.42.0.75
ipv6 addresses work with ping6, ssh -6 without any additional configuration



Hardware that was tested:

Two alfa usb wireless cards from data-alliance.net that I plan to use as wnics or
access points.

this card uses a realtek chip but requires a dual usb connection for the added
power.

this card uses and atheros chip and only requires a single usb connection.
