Open Stack

Guys,

I followed this guide:
https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst
to
build my latest cloud (PoC) and, from within my Instances, I'm facing some
connectivity issues, like this:

---
Instance ip config
---
ubuntu at ubu-1:~$ ip r
default via 10.100.1.1 dev eth0  metric 100
10.100.1.0/24 dev eth0  proto kernel  scope link  src 10.100.1.5
---

---
Test #1 - ping google - okay...
---
root at ubu-1:~# ping -c 1 google.com
PING google.com (74.125.234.110) 56(84) bytes of data.
64 bytes from gru03s08-in-f14.1e100.net (74.125.234.110): icmp_req=1 ttl=57
time=75.7 ms
---

---
Test #2 - install ruby gem "bundler" - not okay...
---
root at ubu-1:~# gem install bundler
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    too many connection resets (
http://production.cf.rubygems.org/gems/bundler-1.3.5.gem)
---

Also, I can ping rubygems server, look:

---
root at cir-1:~# ping production.cf.rubygems.org
PING d2chzxaqi4y7f8.cloudfront.net (54.230.58.161) 56(84) bytes of data.
64 bytes from server-54-230-58-161.gru1.r.cloudfront.net (54.230.58.161):
icmp_req=1 ttl=56 time=5.09 ms
---

And I can telnet it too!

---
root at cir-1:~# telnet production.cf.rubygems.org 80
Trying 54.230.58.161...
Connected to d2chzxaqi4y7f8.cloudfront.net.
Escape character is '^]'.
^]quit
---

But "gem install bundler" always fails...

>From within ubu-1's gateway, the "network node" with l3 agent + namespaces,
"gem install bundler" works as expected...

Weird thing is, I can run "apt-get update / upgrade" without any issues on
"ubu-1" instance... Everything is just opened to the Internet...

All tenants have this weird problem... I tried different setups but, can't
figure it out by myself... I appreciate any help!

I'm running tcpdump at the network node, while trying to run "gem install
bundler" from within "ubu-1" instance:

---
root at network:~# ip netns exec qrouter-475257b2-836c-43a1-98a8-8f29ae1ce1b5
tcpdump -i qr-7a44c1d0-7e
---

Output:
---
02:27:42.279268 IP 10.100.1.5 > server-54-230-58-171.gru1.r.cloudfront.net:
ICMP 10.100.1.5 unreachable - need to frag (mtu 1454), length 556

>From within network node (ubu-1 instance gateway), gem install it works...

---
root at network:~# gem install bundler
Fetching: bundler-1.3.5.gem (100%)

Any thoughts?! Apparently, the package didn't goes back to the Instance...
But I don't know how to fix it...    =P

I tried a lots of variants of this setup (playing with quantum networks,
routers and Floating IPs) but, no success... I can't run "gem install
bundler" form within any Instance... But I can navigate, use apt-get update
and etc...    :-/

NOTE: I noted that the rubygems is hosted at the AWS + CloudFront, and, the
IP of it keep changing... It differs a bit from this mail and pastebin that
I posted.

NOTE 2: The ubu-1 have no Floating IP attached to it, I'm trying to run
"gem install bundler" from VNC console after changing "ubuntu" user
password... Everything here is based on Ubuntu 12.04.2 + Grizzly from UCA,
including Instances (ubu-1) and servers (network, controller, node, etc)...

Tks!
