Comment 6 for bug 717166

Hi Dan,

I was looking at it... here are the messages logged in the cc.log for DHCPD:

[Tue Mar 22 20:19:59 2011][027210][EUCADEBUG ] refresh_instances(): node 10.55.55.3 idle since 1300839443: (156/300) seconds

I then looked at the syslog, and what I see is this:

And, indeed, the /var/lib/eucalyptus/net/euca-dhcpd.conf does not contain any reference to the 10.55.55.0/24 range:

# automatically generated config file for DHCP server
default-lease-time 1200;
max-lease-time 1200;
ddns-update-style none;

shared-network euca {
subnet 172.19.1.0 netmask 255.255.255.224 {
  option subnet-mask 255.255.255.224;
  option broadcast-address 172.19.1.31;
  option domain-name-servers 10.55.55.1, 10.55.55.100;
  option routers 172.19.1.1;
}

host node-172.19.1.4 {
  hardware ethernet D0:0D:46:86:07:8D;
  fixed-address 172.19.1.4;
}
}

This is an all-in-one install, BTW.
