[Server-devel] fresh 0.6 install

Fri Oct 2 11:39:40 EDT 2009

In the end I've decided to try another fresh install.

I think my main problem was in assuming that if a second nic is present in 
the box, that the install would configure it for the lan even if there is 
nothing connected to it, since fc picks it up as present.  (Still seems like 
a desireable feature to me if possible)

This time the three nics have the following connections:

eth0 - connected to switch connected to adsl (as before)
eth1 - connected to lan port on ap (no connection on this nic before) (this 
is a Belkin F5D7230-4 Ver. 7000; dhcp turned off, on 192.168.2.  It's not in 
ap mode, but I don't use the wan port)
eth2 - connected to switch (port is a mirror so not connected to anything)

did install

ran /etc/sysconfig/olpc-scripts/domain_config testschool.org

rebooted

dhcpd is running
ejabberd is running

my laptop can connect to the ap and receives ip address 172.18.96.2!!

service network status shows eth0, eth1, eth2, lanbond0 configured and eth0, 
eth1, lanbond0 active.
