Squid apparently is not well suited to serve up cached pages when no internet
access is
available. It was recommended that I use WWWOFFLE for this situation. Here is
the
process I used to get it installed and running on my 0.6 XS server:
- Make sure that squid is turned off
> /etc/sysconfig/olpc-scripts/TURN_SQUID_OFF
> service iptables restart
- Create a directory for downloads (optional) and download and install the
wwwoffle file
> mkdir /downloads
> cd /downloads
> wget http://dl.atrpms.net/all/wwwoffle-2.8b-2.0.1.el5.i386.rpm
> yum --nogpgcheck localinstall
/downloads/wwwoffle-2.8b-2.0.1.el5.i386.rpm
- When the installation finishes you need edit the wwwoffle.conf file to
configure it for the XS
>ed /etc/wwwoffle.conf
- Change the line " http-port = 8080" to " http-port = 3128" using the
search "/" and change "c" commands as follows:
/http-port / (search till you get to the line " http-port =
8080")
c
http-port = 3128
^c (<control-c> stops the changing)
- In a similar manner search for and change the following in the LocalHost
section:
" localhost" to "YourDomain.org" (In my case this is
"asilong.org")
- Add a line in the "LocalNet" section to get:
LocalNet
{
*.YourDomain.org (In my case this is "*.asilong.org")
- Add a line in the "AllowConnectedHosts" section to get:
AllowedConnectedHosts
{
172.18.96.* (Add any other AP IP groups as needed)
- Write the changes "w" to save them and quit the editor "q"
w
q
- Start the wwwoffle daemon
> wwwoffled -c /etc/wwwoffle.conf
> wwwoffle -online (For when your internet connection is online)
> wwwoffle -offline (For when your internet connection is offline)
- Turn your XO proxy settings on using Browse and going to the URL about:config
- filter the word "proxy" and double-click to adjust the settings to:
network.proxy.http (172.18.0.1)
network.proxy.http_port (3128)
network.proxy.type (1)
Teachers can now download pages of interest and then students can access them
quickly, even if the server has no internet connection simply by putting
wwwoffle -offline.
Give this a try if your internet service is intermittent, or you are paying by
the GB for
your data download.
