do not show a "Register Again" option, except on that 1 single
machine that registered successfully back on Saturday.
<br>
<br>
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.
<br>
<br>
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.
<br>
<br>
Anything else I can try?
<br>
<br>
<br>
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. <br>

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.<br>
<br>
Workaround:<br>
<br>
<br>
1) Turn on DNS in /etc/named-xs.conf.in then run:<br>
[root@schoolserver ~]# nano /etc/named-xs.conf.in<br>
changing this line...<br>
forwarders {196.2.1.2; 196.2.1.3;};<br>
to this line...<br>
forwarders { 192.168.1.1; };<br>
[root@schoolserver ~]# xs-domain-config<br>
[root@schoolserver ~]# service named restart<br>
<br>
<br>
2) Turn off all Internet except pings for our 4- and 5- year olds,
at XS's firewall:<br>
[root@schoolserver ~]# nano
/etc/sysconfig/olpc-scripts/iptables-xs.in<br>
# COMMENTED OUT THESE LINES BELOW, TO BLOCK KIDS FROM INTERNET<br>

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