^ I think this is both incorrect and unnecessary.
For correctness it should be DHCPDARGS="wlan0";
But as long as wlan0 is assigned to the 172.18.96.0 network then you do not
need to limit the configuration to an interface.
What are you using for a configuration:
-WAN - eth0 - XS - eth1 - switch - AP - XO?
-WAN - etho - XS - wlan1(1)- XO? In which case, what are you using to share the
wlan connection?
When the XO does connect, what does it receive for an IP address?

[Server-devel] DNS/DHCP configuration questions/issues
Dear XS fellows,
We are currently configuring the XS server for the deployment in
Madagascar and have some issues on the DNS/DHCP.
Could you resume the main part of the DNS/DHCP config on the XS (using
2 interfaces : eth0 for WAN uplink, wlan0 for LAN wifi delivering IPs,
DNS to XOs)
=>We dont seem to have the domain and nameserver propagated to the
/etc/resolv.conf of the XOs
=>Our /etc/dhcp-xs.conf is :
#
# School server 1 DHCP Server Configuration file.
#
ddns-update-style interim;
#ignore client-updates;
option domain-name "nosykomba.org";
option domain-name-servers 172.18.96.1;
option ntp-servers 172.18.96.1;
DHCPDARGS=wlan0
subnet 172.18.96.0 netmask 255.255.224.0 {
option routers 172.18.96.1;
option subnet-mask 255.255.224.0;
option broadcast-address172.18.127.255;
# this is the whole range we have available - 8K addresses
# range 172.18.96.2 172.18.127.254;
# instead, we'll save 510 addresses for later.
range 172.18.96.2 172.18.125.254;
# the other /24s:
# -> 172.18.126.0/24 for static IP addresses
#for printers, AP management consoles, etc.
# -> 172.18.127.0/24 for temporary addresses for
#XO activation
# As this subnet is wired or wifi a/b/g, these lease
#times are on the long side
default-lease-time 10800;
max-lease-time 21600;
}
Our best regards,

Re: [Server-devel] Database error troubleshooting
Regarding below, on the Moodle forum I was advised to try deleting the Moodle config.php file (after backing up) and it would then bring up the install page to regenerate it. However, when I test this on my local XS (0.6) it says install.php not found. Looking for tips how to regenerate the database connection. David Subject: Re: [Server-devel] Database error troubleshooting Would appreciate any more tips on why the Moodle database connection is in error. My resource person in PNG has repeated tests on the XS and confirms service postgresql status and service httpd status both report postmaster/httpd services are running OK, but the Moodle home pages states database error. I can research this error for default Moodle installations but don't know if there are any specifics related to the XS Moodle configuration.

We already established disk space is OK. It's a default 0.6 installation. service postgresql status - gives "postmaster is stopped" service httpd restart - stops and starts up OK it pings the FQDN and the shortcut schoolserver OK on the XS and an XO using Terminal. Any help with this appreciated. It is difficult to have to reinstall it, as no-one there has the skills.

The reason that I ask, is that I imagine if the Unix domain socket was missing due to an accident, rebooting would start the database server component again and create the Unix domain socket. But I'm really not sure what other conditions might lead to the same symptom. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
