Not picking up public ips

[oldhoot]

In spite of the eucalyptus.local.conf file appearing correct, my instances are launching with the public ip equal to the local ip. Any suggestions as to where to look as to why?

[raymdt]

What VNET_MODE do you use?
can you post your eucalyptus.conf , eucalyptus.localconf and /var/run/eucalyptus/net/euca-dhcp.conf ?

If you are sure that the available public's Ip range is unused then override the
VNET_PUBLICIPS in eucalyptus.conf and restart with CLEAN=1 (may be the Node too).

Hi your config is a bit tricky,
you should first try to make your UEC work before dealing with complex network settings.

What ist the right DNS Address? ( 172.16.230.115 or 169.154.151.130)
Can you use another ip range for public ip's ? (ex. 10.xxx.xxx.xxx or 192.168.xxx.xxx) So you can better see the difference between privates an public ip's.

Edit the local.conf ( if it still not works ) then make a clean restart.

Please read this ( The section about MANAGED_VLAN )

At this stage my intent is not to be tricky and my cloud is working, meaning I can log into instances I create (assuming I use the private IP). I will draw a picture of where I'm heading and get back to you.

[oldhoot]

Didn't answer your question.....

DNS should be 172.16.230.115. And am I reading correctly in that I should try editing the .local.conf file directly? But I guess I remain confused. The local.conf file has the right public IP range, why isn't it being used and passed to the instances? And where did the dhcp configuration get the 172.19.1.0 subnet from?

[oldhoot]

Here's a picture of what I'm trying to assemble. All addresses shown are the actual physical addresses of the connections (no virtual). I really don't care what the virtual subnet is just so I can manage instances from the client computer over the 172.16.230.0 subnet. The 10.10.10.0 subnet is the very private 10GigE link I ultimately want to test.

And am I reading correctly in that I should try editing the .local.conf file directly

I tried it today on my both "Test-clouds" then made a clean restart and there was no problem. I did it because i was curious to know what would happen ( I experience a lot with my Test-clouds , so i can learn more about UEC )

So, do it only if you know what you do -

Did you tried to use another ip range (10.xxx.xxx.xxx or 192.168.xxx.xxx) for public IP?

[raymdt]

Now i understand what you mean

So, try to use subnetz 192.168.0.0 for your private Ips (Eucalyptus will configure a 192.168.1.1 route on your frontend) Just activate IP FORWARDING AND MASQUERADE on your Frontend

172.16.230.201 -....... 210 for public ips

Also, put this in you eucalyptus.local.conf and eucalyptus.conf file

VNET_ADDRSPERNET="32"
VNET_SUBNET="192.168.0.0"
VNET_NETMASK="255.255.255.0"
VNET_DNS="172.16.230.115"
VNET_PUBLICIPS="172.16.230.201-172.16.230.210"

do stop eucalyptus-cc CLEAN=1 then start eucalyptus CLEAN=1
and it should work.

Thanks for the help. I'll be back with results.
