So, I seem to have everything working but one final piece. When I ssh to the external ip of the instance it logs me into the controller not the nodes xen instance. I can log into it via its internal ip no problem. It seems IPTables is not forwarding the packets. How can I debug this? Here are my details:

Euc 5.1.1 x86_64
CentOS 5.3
MANAGED NO-VLAN

Should I have IPTables running or will Euc start it like it does the dhcp server? Aany help you can give would be great.

Thanks,

Aimon

Re: Controller not routing "external" ip to node "internal" ip

Aimon,

Lets take a look at the state of iptables when you encounter this behavior; please try to replicate the scenario, then send us the output of the following commands:

on the front-end:

iptables -t nat -n -L
iptables -n -L
ip addr show dev (VNET_INTERFACE)
brctl show
ps ax | grep dhcpd

on the node:

brctl show

With this information, we should be able to narrow down the problem.

Thanks,
-dan

Ok, so I found another ticket with a user having same issue. The problem is actually a bug in 1.5.1. I upgraded to 1.5.2 and it works beautifully now. Now I just need to find out how to set hostnames as they are all localhost :D.

Hello,

I am having a similar problem in Eucalyptus 1.5.1 in MANAGED mode.
Could you post a link to this bug?

Hi Aimon,

I upgraded to 1.5.2 but the problem is still there.... :(

Perhaps I didn't do the upgrade correctly? I can try again, I suppose.

Do you know if there is a way to check the current Eucalyptus version?

Hello,

on recent version (1.5.2) you can use euca_conf --version to tell the Eucalyptus version.

Graziano,

I tried the euca_conf --version command and --version was not recognized.

Somehow the upgrade to 1.5.2 did not work.
I'll try upgrading again.

Thanks,

Erika
