That single XO-1.5 registered successfully (back on Saturday)
regardless whether its My Settings -> Network -> Server was set to
schoolserver.providence.uwimona.edu.jm or was not set to anything at all.
As of Monday/now however, XO-1.5s cannot similarly register, no matter
if My Settings -> Network -> Server is set or not, even with
schoolserver.providence.uwimona.edu.jm remaining pingable.
Anything else I can try?
Aside: all XO-1.5s are running 11.2.0, and if we can resolve this
register-then-backup dilemma, our intent is to reflash all to 11.3.1.
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@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@schoolserver ~]# xs-domain-config
[root@schoolserver ~]# service named restart
2) Turn off all Internet except pings for our 4- and 5- year olds, at
XS's firewall:
[root@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@schoolserver ~]# xs-setup-network
[root@schoolserver ~]# service iptables restart
[root@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

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@schoolserver ~]# mv /etc/httpd/conf.d/munin.conf
/etc/httpd/conf.d/munin.conf.SAVE
[root@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:
