Lab 3.2
Hi,
I am unable to complete Lab 3.2 step #6, access the BUI. I completed the workaround steps listed in the Lab 2 discussion however I am still unable to connect. Are we still waiting for Labs 3 & 4 to be fixed by the infrastructure team?
Thanks,
Christopher

I completed this only two days ago and it was successful. Click quit and start the lab again ?
I did not need to use and workarounds.

Christopher,
These steps were tested and worked since the roll-out of the new lab environment. Not to say that a new issue could not have happened since then. What is the issue you are finding? Is it a particular error or other situation that may help with the troubleshooting?

I may be experiencing another user error however I am still unable to login. After the script (stack.sh) finishes running I try to use the IP address of my host to access the BUI, 192.168.97.2 . The error I receive in my browser is "This site can't be reached." I am also unable to ping the IP address of my host from my workstation.
I found the following warnings in the stack.sh.log but not sure if they are preventing me from reaching the BUI

Hello Christopher,
There are two things to look at:
First: It would seem you are using the internal IP address to gain access instead of the public IP address. The 192.168.0.0 address range is protected and does not work across the Internet. If there is no exit trap statement in the ./stack.sh logs then chances are the horizon system is working, but you are not requesting the proper IP.
If you were to look at the output of the ip a command you should find your public IP address under fhe eth0 interface as seen in this example I have just run in the labs: 192.237.213.211 (your public IP will be different)
ubuntu@devstack-cc:~$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN grou p default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast sta te UP group default qlen 1000 link/ether bc:76:4e:04:c0:77 brd ff:ff:ff:ff:ff:ff inet 192.237.213.211/24 brd 192.237.213.255 scope global eth0 valid_lft forever preferred_lft forever inet6 2001:4800:7813:516:be76:4eff:fe04:c077/64 scope global valid_lft forever preferred_lft forever inet6 fe80::be76:4eff:fe04:c077/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast sta te UP group default qlen 1000 link/ether bc:76:4e:04:c0:cd brd ff:ff:ff:ff:ff:ff inet 10.100.32.14/20 brd 10.100.47.255 scope global eth1 valid_lft forever preferred_lft forever inet6 fe80::be76:4eff:fe04:c0cd/64 scope link valid_lft forever preferred_lft forever 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast sta te UP group default qlen 1000 link/ether bc:76:4e:04:c0:70 brd ff:ff:ff:ff:ff:ff inet 192.168.97.1/24 brd 192.168.97.255 scope global eth2 valid_lft forever preferred_lft forever inet6 fe80::be76:4eff:fe04:c070/64 scope link valid_lft forever preferred_lft forever
Second: I'm unsure which lab you are having this issue with. I would guess from the 192.168.97.2 ip address you used that you are on the compute-node system right after adding it to the cloud.. If you have just run the ./stack.sh script on this node to join the cluster, the services running on compute-node would depend on what was enabled in the local.conf. The example local.conf file we use in the book for the compute-node does not load horizon on the compute-node. It only enables enough for nova to spawn instances and use storage. Please go to the public address (again eth0) of your devstack-cc node and try to find the horizon BUI at the its public IP address.
If either of these does not work please reply with the entire output of your ip a command and we can try to troubleshoot further.

Thanks for responding. Sadly I did not properly follow the directions.
On your local system open a browser and point it at the public IP Address of your devstack-cc node.
I was trying to use the public IP Address of the compute-node.
Thank you,
Christopher

LFS252 Labs -> cannot access Horizon dashboard in Lab# 2 Task# 5:
ubuntu@devstack-cc:~/devstack$ ip a s eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
inet 166.78.156.39/24 brd 166.78.156.255 scope global eth0
trying Horizon Dashboard:
http://166.78.156.39/dashboard/auth/login/?next=/dashboard/ -> Not Found
http://166.78.156.39 -> gives Apache page (so Apache appears to be running on the devstack node, just not Horizon.?..)
- what am I missing?
