Jerry Vonau's not only Canajun, he also has PAPAL powers (!) exposing a 
serious bug blocking Jamaica's XO-1.5s (Release 11.2.0 for now) from 
registering with their XS 0.7 _unless_ live DNS is turned on.

Workaround:


1) Turn on DNS in /etc/named-xs.conf.in then run:
[root at schoolserver ~]# nano /etc/named-xs.conf.in
     changing this line...
     forwarders {196.2.1.2; 196.2.1.3;};
     to this line...
forwarders { 192.168.1.1; };
[root at schoolserver ~]# xs-domain-config
[root at schoolserver ~]# service named restart


2) Turn off all Internet except pings for our 4- and 5- year olds, at 
XS's firewall:
[root at schoolserver ~]# nano /etc/sysconfig/olpc-scripts/iptables-xs.in
     # COMMENTED OUT THESE LINES BELOW, TO BLOCK KIDS FROM INTERNET
     # -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
     # -A FORWARD -o @@WAN@@ -j ACCEPT
[root at schoolserver ~]# xs-setup-network
[root at schoolserver ~]# service iptables restart
[root at schoolserver ~]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere            state 
RELATED,ESTABLISHED
ACCEPT     icmp --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere
ACCEPT     tcp  --  anywhere             anywhere            state NEW 
tcp dpt:ssh
ACCEPT     all  --  anywhere             anywhere            state NEW
REJECT     all  --  anywhere             anywhere            reject-with 
icmp-host-prohibited

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     icmp --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere
REJECT     all  --  anywhere             anywhere            reject-with 
icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination


3) APACHE WOULD NOT START; was misconfigured, so...
[root at schoolserver ~]# mv /etc/httpd/conf.d/munin.conf 
/etc/httpd/conf.d/munin.conf.SAVE
[root at schoolserver ~]# service httpd restart


4) Jerry hasn't yet figured out why ejabberd (collaboration) isn't 
working, but will try to hack thru these error msgs with me tomorrow, 
when I can get back inside the school:
[root at schoolserver ~]# service moodle restart
